This work was carried out to study the effect of adding drinking water with either, copper sulfate, ascorbic acid or drinking cooled water on growth performance (live body weight,body weight gain, feed intake, feed conversion and water consumption), digestibility coefficients of nutrients, carcass traits, some physiological parameters and economical efficiency of growing NZW rabbits under Egyptian summer conditions. Ninety six weanling New Zealand White (NZW) male rabbits at five weeks of age and nearly similar average body weight (650.3 ±3.7 g) were randomly divided into eight treatment groups (twelve rabbits in each group), and then each group was subdivided into four replicates, each of three rabbits. The rabbits were assigned to drinking water as follow: the 1 st group was given fresh tap water without any additives as a control. The 2 n d, 3 r d and 4 t h groups were given tap fresh water supplemented with copper sulfate at levels of 40, 80 and 120 mg/L drinking water, respectively. The 5 t h, 6 t h and 7 t h groups were given tap fresh water supplemented with ascorbic acid at levels of 250, 500 and 750 mg/L drinking water, respectively. The 8 t h group was given cooled drinking water (CW) at 10-15 degree C. Results showed that supplementation of 40 or 80 mg copper sulfate/L or 500 mg ascorbic acid/L to heat-stressed rabbits drinking water improved final live body weight, body weight gain, daily water consumption, feed conversion ratio, performance index and economical efficiency. Hot carcass percentage was significantly (P<0.01) decreased with 80 mg/L copper sulfate and increased significantly (P<0.01) due to supplementation the drinking water with 250 mg ascorbic acid/L. Cooled water (10-15 degree C) improved significantly (P<0.01) each of final body weight, body weight gain, feed conversion ratio, performance index, economical efficiency and decreased significantly (P<0.01) each of hot carcass %, dressed weight %, heart %, total giblets %, rectal

Evidence pertaining to the role of dietary factors in carcinogenesis comes from both epidemiological studies and laboratory experiments. In 1982, the Committee on Diet, Nutrition, and Cancer of the National Research Council conducted a comprehensive evaluation of this evidence. That assessment as well as recent epidemiological and laboratory investigations suggest that a high fat diet is associated with increased susceptibility to cancer of different sites, particularly the breast and colon, and to a lesser extent, the prostate. Current data permit no definitive conclusions about other dietary macroconstituents including cholesterol, total caloric intake, protein, carbohydrates and total dietary fiber. Specific components of fiber, however, may have a protective effect against colon cancer. In epidemiological studies, frequent consumption of certain fruits and vegetables, especially citrus fruits and carotene-rich and cruciferous vegetables, is associated with a lower incidence of cancers at various sites. The specific components responsible for these effects are not clearly identified, although the epidemiological evidence appears to be most consistent for a protective effect of carotene on lung cancer and less so for vitamins A and C and various cancer sites. The laboratory evidence is most consistent for vitamin A deficiency and enhanced tumorigenesis, and for the ability of various nonnutritive components in cruciferous vegetables to block in-vivo carcinogenesis. The data for minerals and carcinogenesis are extremely limited, although preliminary evidence from both epidemiological and laboratory studies suggests that selenium may protect against overall cancer risk. 402 references.

The present work was designed and carried out at food irradiation research department , National Center for Radiation Research and Technology (NCRRT), Nasr City, Cairo , Egypt , in co-operation with animal production department, faculty of agriculture, Moshtohor, Benha University. The main target of the present study was to evaluate, improve and upgrade the utilization of olive cake and the possibility of replacing part of (clover hay) in rabbits diets by either non-or irradiated processed olive cake with gamma irradiation at dose levels of 20 and 60 kGy . The performance of growing rabbits digestibility, nutritive values of experimental diets, alongside some blood haematological and biochemical parameters, violability rate and economical efficiency were also studied. The growing rabbits were fed on diets without olive cake by - product (control diet) , or with 15% raw or processed olive cake at the above mentioned radiation dose (20 and 60 kGy) from cobalt-60 radioisotopes. Accordingly, a total of 4 experimental diets were used. The experimental diets were formulated to be iso-nitrogenous ( ∼ 17% CP), iso - caloric (∼2500 kcal DE/kg diet) and to , satisfy the nutrients requirements of growing rabbits according to agriculture ministry decree (1996)
Full Text Available Specific knowledge of the nutritive value of raw materials is fundamental to formulate balanced diets for rabbits and allows greater use of by-products and non-conventional feedstuffs. This paper examines the feeding value of sun-dried brewers’ grain and maize silage (whole plant for fattening rabbits. Twenty-four individually caged 8-wk-old rabbits were used to determine the digestibility. Both wet products were sun-dried and ground before being incorporated into a basal diet. The inclusion level at the expense of all basal ingredients amounted to 30%. Basal diet and both experimental diets were fed ad libitum to 8 rabbits during the 4-d balance trial. The determined digestibility of protein, fat, crude fibre and neutral detergent fibre digestibility amounted to 76.2 and 77.2%; 86.5 and 99.1%; 8.1 and 8.3% and 28.0 and 13.5%, respectively, for brewers’ grain and maize silage. The digestible energy content amounted to 11.66 MJ/kg dry matter (DM (brewers’ grain and 11.10 MJ/kg DM (maize silage. Both by-products have potential as alternative feedstuff in rabbit diets. However, further experiments are necessary to determine the effect of ensilaging the whole maize plant, as a significantly lower (P<0.001 feed intake was observed.
The paper stresses the difficulties to establish nutritional standard due to the fact that non-existent previous parameters because it is an new type of accident, becoming necessary an elaboration and use of nutritional plans coherent with probable demands, needs and complications of the patients. It is shown how that was accomplished without any prejudice to the other inpatients. The role of the nutritionists in all evolutional phase of the contaminated persons is described ed, introducing many types of diets used in accordance with individual and general demands. One case in which parenteral nutrition was utilized is analysed. The patients discharge from hospital conditions is explained and was a fact that all patients gained weight, concluding the writer says that was not possible to perform a deeper evaluation because of the great risk of contamination always present.

Nutrition is an important "modifiable" factor in the development and maintenance of bone mass and in the prevention of osteoporosis. The improvement of calcium intake in prepuberal age translates to gain in bone mass and, with genetic factor, to achievement of Peak Bone Mass (PBM), the higher level of bone mass reached at the completion of physiological growth. Individuals with higher PBM achieved in early adulthood will be at lower risk for developing osteoporosis later in life. Achieved the PBM, it is important maintain the bone mass gained and reduce the loss. This is possible adopting a correct behaviour eating associated to regular physical activity and correct life style. The diet is nutritionally balanced with caloric intake adequate to requirement of individual. This is moderate in protein (1 g/kg/die), normal in fat and the carbohydrates provide 55-60% of the caloric intake. A moderate intake of proteins is associated with normal calcium metabolism and presumably does'nt alter bone turnover. An adequate intake of alkali-rich foods may help promote a favorable effect of dietary protein on the skeleton. Lactose intolerance may determinate calcium malabsorption or may decrease calcium intake by elimination of milk and dairy products. Omega3 fatty acids may "down-regulate" pro-inflammatory cytokines and protect against bone loss by decreasing osteoclast activation and bone reabsorption. The diet is characterized by food containing high amount of calcium, potassium, magnesium and low amount of sodium. If it is impossible to reach the requirement with only diet, it is need the supplement of calcium and vitamin D. Other vitamins (Vit. A, C, E, K) and mineral (phosphorus, fluoride, iron, zinc, copper and boron) are required for normal bone metabolism, thus it is need adequate intake of these dietary components. It is advisable reduce ethanol, caffeine, fibers, phytic and ossalic acid intake. The efficacy of phytoestrogens is actually under investigation. Some
Full Text Available Measuring the quality of the nutritional resources available to wild herbivores is critical to understanding trophic regulation processes. However, the direct assessment of dietary nutritional characteristics is usually difficult, which hampers monitoring nutritional constraints in natural populations. The feeding ecology of ruminant herbivores has been often assessed by analyzing fecal nitrogen (FN concentrations, although this method has been less evaluated in other taxa. This study analyzed the suitability of FN as an indicator of ingesta quality in the European rabbit (Oryctolagus cuniculus, which is a keystone lagomorph species in Mediterranean ecosystems and of great conservation interest. Firstly, domestic O. cuniculus were used to evaluate under experimental conditions the accuracy of total FN and the metabolic FN as diet quality indicators of forages with characteristics similar to those available under natural conditions. Secondly, the accuracy of Near-Infrared Spectroscopy (NIRS to calculate FN was tested using partial least squares regression. Thirdly, a pilot field study was conducted to monitor FN dynamics from wild O. cuniculus in three different habitats during wet and drought periods. A strong association was found between diet type and total FN and metabolic FN (Pseudo-R(2 ≥ 0.89. It was also found that NIRS calibrations were accurate for depicting nitrogen concentrations (R(2 > 0.98 between NIRS and chemical results. Finally, the seasonal FN dynamics measured in the field were consistent with current knowledge on vegetation dynamics and forage limitations in the three habitats. The results support the use of NIRS methods and FN indices as a reliable and affordable approach to monitoring the nutritional quality of rabbit habitats. Potential applications include the assessment of the mechanistic relationships between resource limitations and population abundance, e.g., in relation to natural drought cycles and to habitat

Kefiran is an exopolysaccharide produced by Lactobacillus kefiranofaciens, and has been proposed to have many health-promoting properties. We investigated the antiatherogenic effect of kefiran on rabbits fed a high-cholesterol diet. Male New Zealand White rabbits were fed a 0.5% cholesterol diet without (control group, n = 7) or with kefiran (kefiran group, n = 8) for eight weeks. The aorta was analyzed by histochemistry and atherosclerotic lesions were quantified. Lipids and sugars in serum were measured. Foam cell formation of RAW264.7 by βVLDL derived from both groups of rabbits was also investigated. Cholesterol, triglyceride and phospholipids levels of serum and lipoprotein fractions were not significantly different between these groups. Atherosclerotic lesions of the aorta in the kefiran group were statistically lower than those of the control group, with marked differences in the abdominal aorta. T-lymphocytes were not detectable in the aorta of the kefiran group. Cholesterol contents in stools were almost identical in both groups. Cholesterol content in the liver of the kefiran group was statistically lower than in the control group. Galactose content of βVLDL derived from the kefiran group was higher, and the lipid peroxidation level was much lower than in the control group. RAW264.7 macrophages treated with βVLDL from the kefiran group showed a more spherical shape and accumulated statistically lower cholesterol than macrophages treated with βVLDL from the control group. Orally derived kefiran is absorbed in the blood. Kefiran prevents the onset and development of atherosclerosis in hypercholesterolemic rabbits by anti-inflammatory and anti-oxidant actions.

The ends of human chromosomes are protected by DNA-protein complexes termed telomeres, which prevent the chromosomes from fusing with each other and from being recognized as a double-strand break by DNA repair proteins. Due to the incomplete replication of linear chromosomes by DNA polymerase, telomeric DNA shortens with repeated cell divisions until the telomeres reach a critical length, at which point the cells enter senescence. Telomere length is an indicator of biological aging, and dysfunction of telomeres is linked to age-related pathologies like cardiovascular disease, Parkinson disease, Alzheimer disease and cancer. Telomere length has been shown to be positively associated with nutritional status in human and animal studies. Various nutrients influence telomere length potentially through mechanisms that reflect their role in cellular functions including inflammation, oxidative stress, DNA integrity, DNA methylation and activity of telomerase, the enzyme that adds the telomeric repeats to the ends of the newly synthesized DNA.

The voluntary dry matter intake (DMI) of several grass and legume diets, and the amount of dry matter (DM), nitrogen, fibre, and energy assimilated from each diet (i.e. the digestibility coefficients) are presented for the wild European rabbit Oryctolagus cuniculus. The DMI may be predicted from DM% and percentage of total nitrogen (on a DM basis) for a high DM diet (90-95%) but the general relationship may stand for fresh forage also. The metabolizable energy of a diet is correlated with DMI through the DM% and the percentage of nitrogen and fibre in the diet on a DM basis. The DM digestibility coefficient is correlated with fibre content. The wild rabbit's high efficiency of protein digestibility and low fibre digestibility compared with ruminants is also a characteristic of the domestic rabbit. It is suggested that the proportions of different nutrients required by wild rabbits are similar to those required by domestic animals.

Full Text Available A total of 70 five-month-old female New Zealand White rabbits were assigned in a completely randomized design, over three reproductive cycles, with two treatments: a reference diet and a half-simplified diet containing 79.83% cassava byproduct. The study evaluated body weight and feed intake of does, feed cost, number and total body weight of kits at kindling and weaning per female during three cycles, number and percentage of mortality/female/cycle, and weight gain of kits from birth to weaning. No interaction was observed between the diets and among the reproductive cycles for any evaluated characteristics. The body weight of does at the moment of weaning was similar in both groups for all three reproductive cycles. However, does fed the half-simplified diet had lower feed intake during the three reproductive cycles and, consequently, more reproductive flaws. The number of kits at weaning, body weight of kits at kindling and weaning, weight gain of kits from birth to weaning, and total body weight of kits at weaning were lower for the group of does fed the half-simplified diet and, consequently, there was a higher number and percentage of dead kits in this group. The total numbers of kits at kindling and weaning and total body weight of kits at birth during all three reproductive cycles were similar between the groups; however, total body weight of weaning rabbits was higher for the animals receiving the reference diet. It is possible to conclude that although the use of the half-simplified diet decreases the reproductive performance of does, it reduces feed cost per kg of body weight by 23.63% compared with the reference diet, proving to be a viable nutritional option for rabbit production.

Full Text Available This study aimed to evaluate the effect of feeding dried foliage (leaves and petioles of Acacia saligna, Leucaena leucocephala or Moringa oleifera on the performance, digestibility, N utilisation, caecal fermentation and microbial profiles in New Zealand White (NZW rabbits. One hundred weaned male NZW rabbits weighing 819.2±16.6 g and aged 35±1 d were randomly allocated into 4 groups of 25 rabbits each. Rabbits were fed on pelleted diets containing 70% concentrate mixture and 30% Egyptian berseem (Trifolium alexandrinum hay (Control diet or one of the other 3 experimental diets, where 50% of berseem hay was replaced with A. saligna (AS, L. leucocephala (LL or M. oleifera (MO. Compared to Control diet, decreases in dry matter (DM; P=0.004, organic matter (P=0.028, crude protein (CP; P=0.001, neutral detergent fibre (P=0.033 and acid detergent fibre (P=0.011 digestibility were observed with the AS diet. However, DM and CP digestibility were increased by 3% with the MO diet, and N utilisation was decreased (P<0.05 with AS. Rabbits fed AS and LL diets showed decreased (P=0.001 average daily gain by 39 and 7%, respectively vs. Control. Feed conversion was similar in Control and MO rabbits, whereas rabbits fed AS diet ate up to 45% more feed (P=0.002 than Control rabbits to gain one kg of body weight. Caecal ammonia-N was increased (P=0.002 with LL, while acetic acid was decreased (P=0.001 with AS diet vs. other treatments. Caecal E. coli and Lactobacillus spp. bacteria counts were decreased with MO by about 44 and 51%, respectively, vs. Control. In conclusion, under the study conditions, tree foliage from M. oleifera and L. leucocephala are suitable fibrous ingredients to be included up to 150 g/kg in the diets of growing rabbits, and can safely replace 50% of berseem hay in diets of NZW rabbits without any adverse effect on their growth performance. Foliage from M. oleifera had a better potential as a feed for rabbits than that from L

An experiment was performed to determine whether boron had a beneficial effect on bone strength and composition in rabbits with apparent adiposity induced by a high energy diet. Sixty female New Zealand rabbits, aged 8 months, were randomly divided into five groups with the following treatments for seven months: control 1, fed alfalfa hay only (5.91 MJ/kg); control 2, high energy diet (11.76 MJ and 3.88 mg boron/kg); B10, high energy diet+10 mg/kg body weight boron gavage/96 h; B30, high energy diet+30 mg/kg body weight boron gavage/96 h; B50, high energy diet+50mg/kg body weight boron gavage/96 h. Bone boron concentrations were lowest in rabbits fed the high energy diet without boron supplementation, which suggested an inferior boron status. Femur maximum breaking force was highest in the B50 rabbits. Tibia compression strength was highest in B30 and B50 rabbits. All boron treatments significantly increased calcium and magnesium concentrations, and the B30 and B50 treatments increased the phosphorus concentration in tibia of rabbits fed the high energy diet. The B30 treatment significantly increased calcium, phosphorus and magnesium concentrations in femur of rabbits fed the high energy diet. Principal component analysis of the tibia minerals showed that the three boron treatments formed a separate cluster from controls. Discriminant analysis suggested that the concentrations of the minerals in femur could predict boron treatment. The findings indicate boron has beneficial effects on bone strength and mineral composition in rabbits fed a high energy diet. Copyright © 2012 Elsevier GmbH. All rights reserved.

Full Text Available Pulps from different citrus fruits are relevant agro-industrial co-products in the Mediterranean area in terms of amounts produced and availability. Moreover, part of the product is dehydrated, which increases its interest in monogastric species such as rabbits. Seventy eight samples from various Spanish producers using several types of fresh fruits (orange, tangerine, lemon and pomelo and different processing methods of orange and tangerine samples (either fresh or dried after adding Ca(OH2 were analysed for their chemical composition and in vitro digestibility. Average dry matter (DM contents of ash, neutral detergent fibre, acid detergent fibre, acid detergent lignin (ADL, soluble fibre, crude protein (CP, insoluble neutral and acid detergent CP, ether extract and gross energy were 49.0, 226, 139, 12.1, 213, 71.2, 13.1, 4.2, 30.5 g and 17.8 MJ/kg DM, respectively. Mean DM and CP in vitro digestibility were 86.7 and 95.6%, respectively. Digestible energy was estimated to be 15.1 MJ/kg DM. A high variability (coefficient of variation from 17% for CP to 60% for ADL was observed among the samples for most of the traits studied, which was partially explained by the effects of type of fruit and processing. Lemon pulps had on average higher ash and fibre but lower sugar contents than the other pulps. Dehydration processes increased ash content (almost double than for fresh pulp due to lime addition. As regards the current results, citrus pulp has potential for use in rabbit diets as a source of energy and soluble fibre.

Simple Summary In addition to hay or forage in the diet pet rabbits are commonly fed a supplementary food as a muesli (granular mix), pellets, or extruded croquettes. This study aimed to determine if form of this supplementary diet (pelleted vs. extruded) or composition (muesli) had an effect on the diets total tract digestibility and cecal fermentation patterns. Rabbits had slightly higher intake when fed extruded and pelleted diets compared to muesli. Digestibility results were inconsistent between estimation methods. The extruded diet was more digestible than pelleted according to the total collection digestibility method, but according to internal marker acid insoluble ash the pelleted diet was the most digestible. Both the extruded and pelleted diet had similar fermentation patterns, with lower cecal pH and greater proportions of butyrate. Our findings suggest that diet composition, rather than form, may have a greater impact on nutrient utilization by rabbits. Abstract Fifteen New Zealand rabbits were randomly assigned to one of 3 dietary treatment groups of 5 animals each and fed pelleted, extruded, or muesli diets in a completely randomized design experiment. Rabbits were placed in individual cages with ad libitum access to water and food for 45 days acclimation followed by 30 days experimental period. Feed intake of rabbits fed pelleted and extruded diets was greater (p digestibility among the treatments was inconsistent when comparing results obtained from total fecal collection and AIA (please define) as an internal marker. Rabbits fed extruded and pelleted diets had lower (p < 0.05) cecal pH (6.42 and 6.38 vs. 7.02, respectively), and higher (p < 0.05) production of SCFA (18.5 and 19.0 vs. 11.7 mM, respectively) than those fed muesli. The fermentation products from rabbits fed pelleted and extruded diets had a greater proportion of butyrate and less propionate than rabbits fed muesli. The results of this study indicate that the basal dietary composition

In this paper, we report on the effects of a diet containing cloned-cattle meat on the reproductive parameters in pregnant rabbits. The artificially inseminated rabbits (gestation day 0) were fed a diet containing 5% or 10% of normal or cloned-cattle meat during the gestation period. Rabbits fed commercial pellet (no additional supplementations) were used as the control. Supplementation of cloned-cattle meat diets did not have any toxicologically significant effects on reproductive performance in dams (body weight, clinical signs, organ weight, and cesarean section analysis). And it also did not affect on fetal development (body and placental weight, and external, visceral and skeletal findings) compared to the controls. The only difference was a food consumption in the first week of gestation for all meat-based diet groups (pmeat. Copyright (c) 2010 Elsevier Ltd. All rights reserved.

Hypercholesterolemia is an important risk factor linked to the alteration of blood hematology and clinical chemistry associated with the development and progression of atherosclerosis. Previous studies have demonstrated the safety and potential health benefits of Baccaurea angulata (BA) fruit. We hypothesized that the oral administration of BA fruit juice could ameliorate the alteration in the hematological and biochemical biomarkers of diet-induced hypercholesterolemic rabbits. The aim of this study was to investigate the effects of different doses of BA juice on the hematological and biochemical biomarkers in normo- and hypercholesterolemic rabbits. Thirty-five healthy adult New Zealand White rabbits were assigned to seven different groups for 90days of diet intervention. Four atherogenic groups were fed a 1% cholesterol diet and 0, 0.5, 1.0, and 1.5mL of BA juice per kg of rabbit daily. The other three normal groups were fed a commercial rabbit pellet diet and 0, 0.5, and 1.0mL of BA juice per kg of rabbit daily. Baseline and final blood samples after 90days of repeated administration BA juice were analyzed for hematological parameters while serum, aortic and hepatic lysates were analyzed for lipid profiles and other biochemical biomarkers. The alteration of the hemopoietic system, physiological changes in serum and tissues lipid profiles and other biochemicals resulting from the consumption of a high-cholesterol diet were significantly (Pjuice. Improvements of the biomarkers in rabbits were dose-dependent, markedly enhanced at the highest dose of juice (1.5mL/kg/day). The results suggest potential health benefits of the antioxidant-rich BA fruit juice against hypercholesterolemia-associated hematological and biochemical alterations in the rabbit.

Atherosclerosis is the most common disease of large and medium-sized arteries linked to oxidative stress, dyslipidemia as well as chronic inflammation. The aim of this study was to evaluate the potential health benefits of Baccaurea angulata (BA) fruit juice on the aorta of diet-induced hypercholesterolemic rabbits, to detect an accumulation of fatty streak and evaluate the percentage of atherosclerotic lesion accrued. Thirty-five healthy male adults New Zealand White rabbits were assigned to seven different groups. Four groups were fed 1% cholesterol diet and 0, 0.5, 1.0, and 1.5 mL of BA fruit juice per kg of rabbit daily (atherogenic groups), while the other three groups were fed commercial rabbit pellet and 0, 0.5, and 1.0 mL of juice per kg of rabbit daily (normocholesterolemic groups) for 90 days. The thoracic and abdominal aorta between the heart origin and bifurcation into iliac arteries of all the rabbits were carefully removed and analyzed accordingly. The supplementation of the high-cholesterol diet of hypercholesterolemic rabbits with only 0.5 mL BA/kg rabbit per day significantly (p < 0.001) improved aortic lipid profile, attenuated aortic fatty streak development and reduced intima thickening. Higher BA doses used (1.0 and 1.5 mL/kg rabbit per day) also significantly (p < 0.001) decreased further the development of aortic fatty streaks, reduced the thickening of the tunica intima layer and preserved endothelial healing following arterial injury. Therefore, BA fruit is a potential novel functional food with effective anti-inflammatory, anti-atherogenic and hypocholesterolemic activities.
Full Text Available Soluble fibre (SF is an important nutrient to enhance fermentative activity and gut health in rabbits. The main source of SF in rabbit diets is sugar beet pulp (SBP, whereas, due to its high content of SF (34%, dried chicory pulp (ChP could be an alternative to SBP. In a fattening trial with 192 hybrid weanlings 32 d old weighing 837±45 g, chicory pulp was used in replacement of SBP to study effects on production performances and slaughter characteristics. Rabbits were fed one of 4 iso-energetic (9.65 MJ digestible energy/kg and isonitrogenous (15.6% crude protein diets: a negative control (NC diet with a low dietary SF content (7.3%, a positive control diet with quite a high SBP level (13.5% and SF content (10.6% and 2 diets with respectively 10% and 20% of chicory pulp (ChP10: 9.9% SF and ChP20: 13.7% SF. The SF content was measured as the difference between total dietary fibre and neutral detergent fibre, the latter corrected for ash and protein content. Each dietary treatment consisted of 12 replicates of 4 rabbits. Weight gain was high (on av. 54 g/d and comparable for the NC, SBP and ChP diets. However, feed conversion ratio was improved (P<0.05 with the ChP20 diet compared to the NC diet (2.88 vs. 2.97. Mortality was low and not influenced by the dietary treatment. Slaughter data were very similar and no effect of the SF level on caecal weight or slaughter yield was observed. It was concluded that chicory pulp is a good alternative soluble fibre source in balanced diets for rabbits and can be used at least up to 20% inclusion rate.

Full Text Available This study aimed to evaluate the effects of a probiotic and/or prebiotic additive on the nutrient digestibility of diets for growing rabbits. Twenty 50-day-old rabbits were used. A completely randomized experimental design, with five treatments and four replicates each, was used. The applied treatments (T were the following: T1 = negative control diet (no growth promoter; T2 = diet with antibiotic, positive control (0.05% zinc bacitracin; T3 = diet with probiotic (0.15% Bacillus subtillis at a concentration of 109 UFC/g; T4 = diet with prebiotic (0.15% phosphorylated mananoligossaccharide at 30%; and T5 = diet with symbiotic (probiotic + prebiotic. The experimental period lasted 12 days, seven for adaptation to the experimental diets and to the cages, and five days of feces collection. The apparent digestibility coefficients of dry matter, organic matter, crude protein, neutral detergent fiber, acid detergent fiber, mineral matter, and ether extract were calculated. The addition of a probiotic and of a symbiotic to the rabbit diet resulted in digestibility similar to that of animals fed diets containing antibiotics or no additive at all. The best digestibility results were obtained with the prebiotic.

Full Text Available This study aimed to evaluate the nutrient digestibility of growing rabbits fed diets with different levels of either Leucaena leucocephala (LLM or Moringa oleifera (MOLM leaf meals and also to compare total collection and TiO2 marker methods for estimating digestibility. A total of 30 California growing rabbits (1.81±0.19 kg live weight on average were randomly distributed into five experimental groups of six rabbits each and were housed in individual cages. The groups were control, 30% LLM, 40% LLM, 30% MOLM, and 40% MOLM. All groups received pelleted diets for two weeks; diets also contained 4 g/kg titanium dioxide as dietary marker. Daily feed intake was recorded during the whole experimental period and total feces were collected daily and weighed individually during four days. The results showed that there were no difference (p>0.05 in feed, dry matter (DM, organic matter (OM, crude protein (CP, digestible energy, and crude fiber (CF intake between the control group and the other experimental groups. The apparent digestibility values of DM, OM, CP, CF, acid detergent fiber, and gross energy were the highest for control group (p = 0.001, meanwhile MOLM diets had generally higher nutrient digestibility coefficients than LLM diets. Increasing the inclusion level of leaf meal in the diet from 30% to 40% improved the digestibility of CF from 45.02% to 51.69% for LLM and from 48.11% to 55.89% for MOLM. Similar results for apparent nutrient digestibility coefficients were obtained when either total collection or indigestible marker method was used. In conclusion, the digestibility of MOLM containing diets were better than LLM diets, furthermore TiO2 as an external marker could be used as a simple, practical and reliable method to estimate nutrients digestibility in rabbit diets.
Full Text Available The aim of this study was to investigate potential hypoglycaemic and hypolipidemic effects of Plantago ovata husk included in the diet, in healthy and diabetic rabbits. We also examined the effects of this fiber in other biochemical parameters. Two groups of 18 rabbits were used. The first group was fed with standard chow and the second with chow supplemented with Plantago ovata husk (3.5 mg/kg/day. On day 14 diabetes mellitus was induced by the intravenous administration of alloxan (80 mg/kg. After an oral glucose load (3 g, glucose, insulin, and other biochemical parameters were determined on day 14 (healthy rabbits and on day 28 (diabetic rabbits. In healthy rabbits, fiber did not modify glucose or insulin levels but decreased significantly total cholesterol, LDL-cholesterol, atherogenic index, and glycosylated hemoglobin. In diabetic rabbits, fiber was more beneficial in mild diabetics than in severe diabetics with significant decreases in glucose levels and increases in insulin concentrations. In these animals fiber caused an important reduction in cholesterol, indicating a beneficial effect of Plantago ovata husk in diabetic rabbits. Although further studies in patients are necessary, we think that Plantago ovata husk offers interesting perspectives to be administered to patients with diabetes mellitus.

This study aimed to investigate the influence of decreased functional load on the medial pterygoid muscle during mastication in rabbits fed with a liquid-diet. Medial pterygoid muscles from 54 rabbits (solid- and liquid-diet groups, n=48; unweaned group, n=6) were histochemically examined at 4, 9, 12, 18, and 33 weeks after birth. Six fiber types (I, IC, IIC, IIA, IIAB, and IIB) were distinguished via mATPase staining. Significant increases in the diameters of all fiber types were seen up to 33 weeks of age in the solid-diet group; however, no significant increase was noted in fiber types I and IC, from 4 to 33 weeks of age, in the liquid-diet group. The proportion of slow fibers increased up to 12 weeks followed by an increase in the number of fast fibers in the solid-diet group, whereas in the liquid-diet group, the number of slow fiber declined after weaning. Liquid-diet consumption caused muscle fiber atrophy and an increase in the number of fast fibers during early developmental stages after weaning. Furthermore, the growth pattern of the medial pterygoid muscle in the liquid-diet group was different from that in the solid-diet group. Copyright © 2017 Elsevier Ltd. All rights reserved.
Full Text Available The present study aimed to investigate the anti-hyperlipidemic effects of sesame in a high-fat fed rabbit model. Animals were randomly divided into four groups of eight animals each for 60 days as follows: normal diet, hypercholesterolemic diet (1% cholesterol, hypercholesterolemic diet (1% cholesterol + sesame seed (10%, and hypercholesterolemic diet (1% cholesterol + sesame oil (5%. Serum concentrations of total cholesterol, LDL-C, HDL-C, triglycerides, apoA and apoB, SGOT, SGPT, glucose and insulin were measured at the end of supplementation period in all studied groups. Hypercholesterolemic feeding resulted in a significant elevation of TC, TG, LDL-C, HDL-C, SGOT and SGPT as compared to the normocholesterolemic diet group (P0.05. In contrast, rabbits supplemented with sesame oil were found to have lower circulating concentrations of TC, LDL-C, HDL-C, SGOT and SGPT (P0.05. Supplementation with sesame oil, but not sesame seed, can ameliorate serum levels of lipids and hepatic enzymes in rabbits under a high-fat diet.
Full Text Available The effects on performance and digestibility in growing rabbits were studied by comparing 3 diets containing increasing inclusion rates of amaranth (Amaranthus dubius Mart. ex Thell.: 0 (A0, 160 (A16 and 320 g/kg (A32 diet. Diets were formulated isoproteic and isocaloric to meet the nutrient requirements of growing rabbits. One hundred and thirteen weaned New Zealand White rabbits (mean±standard deviation weight: 760±102 g, individually caged, were randomly assigned to one of the 3 experimental diets. Rabbits were fed ad libitum from 35 to 87 d of age, and health status and performance traits were onitored. The coefficients of total tract apparent digestibility of the diets were measured between 42 and 46 d of age in 12 rabbits per treatment. Amaranthus dubius contained 209 g/kg dry matter (DM of crude protein and 398 g/kg DM of neutral detergent fibre. There were no significant differences between treatments in weight gain (mean 21.6 g/d and live weight at the end of the fattening period (mean 1883 g. Daily feed intake was higher (P<0.05 in A0 than in A16 and A32 diets (85.4 vs. 73.7 and 69.9 g/d, respectively, and feed conversion rate improved with increased inclusion of A. dubius in the diet (from 3.84 to 3.28 for A0 and A32 diets, respectively; P<0.05. Health status was not affected by the amaranth inclusion rate. Total tract apparent digestibility showed high values, with no differences among diets except for ether extract. Thus, A. dubius could be considered as an alternative source of protein and fibre for rabbit feeding in tropical and subtropical regions.

In a series of experiments carried out on young and adult rabbits the effect of isocaloric low protein diets containing 4% or 8% protein compared with a diet containing 21% protein on Obeliscoides cuniculi infection was studied. The pathogenesis, resistance and local immunity were assessed after single infections with 10,000 larvae or reinfection with 5000 larvae. Live weight gain was reduced in young and adult rabbits fed the low protein diets, but the establishment of parasites was not substantially influenced by protein deprivation. However, development of worms in the histotrophic phase and parasite fecundity were impaired in association with the low protein diet. Moreover, mild anaemia as well as changes in the mucosal immune response as a result of infection were related to the level of dietary protein. (author). 30 refs, 6 figs, 5 tabs

The aim of this study was to evaluate the effect of the level of alfalfa in the diet on feed intake and digestibility of two types of rabbits, wild (Oryctolagus cuniculus algirus) vs. domestic (O. cuniculus cuniculus). Ten wild (W; mean LW = 927 g) and 10 domestic (D; mean LW = 4,645 g) adult rabbit does were fed ad libitum two pelleted diets: a control diet (C) with 15% of dehydrated alfalfa hay (as feed basis) and a test diet (A) with 36% of dehydrated alfalfa hay (as feed basis), according to a change-over design. Wild does dry matter (DM) intake per kg live weight (BW) was 55% higher (p .05) was found when intake was expressed per kg 0.75 BW (ca. 56 g DM) and tended to be higher (p = .07) in D does when expressed per kg 0.67 BW (62 g vs. 55 g DM). Domestic does showed a higher (p digestibility (3; 2; 3; 3 percentage points respectively) than W does. The amount of nutrients and energy digested by D does was lower per kg BW (p .05) and tended to be higher per kg 0.67 BW (p .05) the feed intake nor the diet digestibility. This study suggests that W rabbits exhibit a higher intake per kg BW and a lower digestibility than their D counterparts, which results in similar digestible nutrient and energy intake per kg BW powered to 0.75. The nutritive value of dehydrated alfalfa for rabbits, evaluated through intake and digestibility, seems to be equivalent to their base diets (forage plus concentrate). © 2017 Blackwell Verlag GmbH.

Using content analysis, this study evaluated the aging content and context in 11 nutrition sub-specialty textbooks: community nutrition (n = 3), diet therapy (n = 4), and nutrition and aging (n = 4). Pages with paragraphs on aging were identified in community nutrition and diet therapy textbooks, and 10% random samples of pages were evaluated in nutrition and aging textbooks. Paragraphs were assigned to one of four categories: gerontology, nutrition as primary, nutrition as secondary, or tertiary prevention. A total of 310 pages was qualitatively analyzed using NUD*IST 5 software and quantitatively with percentages. Only 7% of community nutrition and 2% of diet therapy pages were devoted to aging. There was little integration of aging beyond the chapters on aging. Community nutrition had the most gerontology (30%) and primary prevention (43%) content. Diet therapy and nutrition and aging had more secondary prevention (33% and 42%, respectively) and tertiary prevention (27% each) content. Some important databases and studies were absent. Of the 1,239 ageism words, 10% were positive, 53% neutral, and 36% negative. Photographs were generally positive. Women, but not minorities, reflected current older adult demographics. Future textbook editions should address aging more comprehensively and positively to better prepare dietitians for the job market. Recommendations for authors, course instructors, and publishers are given.

Gluten-free diet (GFD) is the cornerstone treatment for celiac disease (CD). GFD implies a strict and lifelong elimination from the diet of gluten, the storage protein found in wheat, barley, rye and hybrids of these grains, such as kamut and triticale. The absence of gluten in natural and processed foods, despite being the key aspect of GFD, may lead to nutritional consequences, such as deficits and imbalances. The nutritional adequacy of GFD is particularly important in children, this the a...
Full Text Available Acacia senegal L. (Fabaceae seeds are essential ingredient of “Pachkutta,” a specific Rajasthani traditional food. The present study explored antiatherosclerotic and cardioprotective potential of Acacia senegal seed extract, if any, in hypercholesterolemic diet-induced atherosclerosis in rabbits. Atherosclerosis in rabbits was induced by feeding normal diet supplemented with oral administration of cholesterol (500 mg/kg body weight/day mixed with coconut oil for 15 days. Circulating total cholesterol (TC, HDL-cholesterol (HDL-C, LDL-cholesterol (LDL-C, triglycerides, and VLDL-cholesterol (VLDL-C levels; atherogenic index (AI; cardiac lipid peroxidation (LPO; planimetric studies of aortal wall; and histopathological studies of heart, aorta, kidney, and liver were performed. Apart from reduced atherosclerotic plaques in aorta (6.34±0.72 and increased lumen volume (51.65±3.66, administration with ethanolic extract of Acacia senegal seeds (500 mg/kg/day, p.o. for 45 days to atherosclerotic rabbits significantly lowered serum TC, LDL-C, triglyceride, and VLDL-C levels and atherogenic index as compared to control. Atherogenic diet-induced cardiac LPO and histopathological abnormalities in aorta wall, heart, kidney, and liver were reverted to normalcy by Acacia senegal seed extract administration. The findings of the present study reveal that Acacia senegal seed extract ameliorated diet-induced atherosclerosis and could be considered as lead in the development of novel therapeutics.

To explore associations between the nutritional quality of diet at age 16 years and academic performance in students from Santiago, Chile. We assessed the nutritional quality of diet, using a validated food frequency questionnaire, in 395 students aged 16.8 ± 0.5 years. Depending on the amount of saturated fat, fibre, sugar and salt in the foods, diet was categorized as unhealthy, fair or healthy. Academic performance was assessed using high school grade-point average (GPA) and tests for college admission in language and mathematics. Academic results on or above the 75th percentile in our sample were considered good academic performance. We tested associations between nutritional quality of diet and good academic performance using logistic regression models. We considered sociodemographic, educational and body-mass index (BMI) factors as potential confounders. After controlling for potential confounding factors, an unhealthy diet at age 16 years was associated with reduced academic performance. Compared to participants with healthy diets, those with unhealthy diets were significantly less likely to perform well based on language tests (odds ratio, OR: 0.42; 95% confidence interval, CI: 0.18-0.98) mathematics tests (OR: 0.35; 95% CI: 0.15-0.82) or GPA (OR: 0.22; 95% CI: 0.09-0.56). In our sample, excessive consumption of energy-dense, low-fibre, high-fat foods at age 16 years was associated with reduced academic performance.

Four vitamins are fat-soluble (vitamin A, O E, and K) and the nine others (vitamins of the B-complex and vitamin C) are water-soluble. The water-soluble vitamins and vitamin K are normally synthesised by the rabbit's digestive flora; but in cases of high risk of digestive disorders (e.g. just after weaning), dietary supplementation may be advisable. In addition, a vitamin C supplementation (...

Full Text Available The primary goal of palliative cancer care is typically to relieve suffering and improve quality of life. Most approaches to diet in this setting have focused only on eating as many calories as possible to avoid cachexia. However, as the concept of palliative care has evolved to include all aspects of cancer survivorship and not just end of life care, there is an increasing need to thoughtfully consider diet and nutrition approaches that can impact not only quality of life but overall health outcomes and perhaps even positively affect cancer recurrence and progression. In this regard, there has been a recent emphasis in the literature on nutrition and cancer as an important factor in both quality of life and in the pathophysiology of cancer. Hence, the primary purpose of this paper is to review the current data on diet and nutrition as it pertains to a wide range of cancer patients in the palliative care setting.

The traditional assumption that children's nutritional deficiencies are essentially due either to overall food scarcity or to a lack of family resources to purchase available food has been increasingly questioned. Parental characteristics represent 1 type of noneconomic factor that may be related to variability in children's diets and nutritional status. We report evidence on the relation of 2 parental characteristics, maternal education level and maternal intelligence, to infant and toddler diet and nutritional status. Our sample consisted of 241 low-income Peruvian mothers and their infants assessed from 3 to 12 mo, with a further follow-up of 104 of these infants at 18 mo of age. Using a nonexperimental design, we related measures of level of maternal education, maternal intelligence, and family socioeconomic status to infant anthropometry, duration of exclusive breast-feeding, adequacy of dietary intake, and iron status. Results indicated unique positive relations between maternal education level and the extent of exclusive breast-feeding. Significant relations between maternal education and offspring length were partially mediated by maternal height. There also were unique positive relations between maternal intelligence and quality of offspring diet and hemoglobin level. All findings remained significant even after controlling for family socioeconomic characteristics. This pattern of results illustrates the importance of parental characteristics in structuring the adequacy of offspring diet. Maternal education and intelligence appear to have unique influences upon different aspects of the diet and nutritional status of offspring.

Full Text Available The objective was to evaluate the effect of nutritional density and season on the performance of young rabbit does before the first mating. Forty-eight females from the Botucatu Genetic Group were used in each season (warm or cool, starting at the age of 70 days, housed in groups of four per cage up to 119 days, and reared individually from 120 to 140 days of age. The high-density diet was formulated to contain, on a 90% DM basis, 18.4% CP, 16.5% ADF and 2,500 kcal DE kg-1; whereas the low-density diet was formulated to contain 14.7% CP, 24% ADF and 2,000 kcal DE kg-1. The experiment was conducted according to a 2x2 factorial design (two diets x two seasons with repeated measures (weeks. The high-density diet promoted lower feed intake, higher final weight, and higher daily weight gain, adjusted for constant intake. But these facts alone do not warrant using a high-density diet for growing rabbit does, because it could have a negative impact during the reproductive phase. In the warm season, there was a reduction in feed intake and an improvement in feed efficiency. Along time, however, the mean body weight of does was similar in the two seasons.

Livestock farming incurs large and varied environmental burdens, dominated by beef. Replacing beef with resource efficient alternatives is thus potentially beneficial, but may conflict with nutritional considerations. Here we show that protein-equivalent plant based alternatives to the beef portion of the mean American diet are readily devisible, and offer mostly improved nutritional profile considering the full lipid profile, key vitamins, minerals, and micronutrients. We then show that replacement diets require on average only 10% of land, 4% of greenhouse gas (GHG) emissions, and 6% of reactive nitrogen (Nr) compared to what the replaced beef diet requires. Applied to 320 million Americans, the beef-to-plant shift can save 91 million cropland acres (and 770 million rangeland acres), 278 million metric ton CO2e, and 3.7 million metric ton Nr annually. These nationwide savings are 27%, 4%, and 32% of the respective national environmental burdens.

The WHO asserts that the global food price crisis threatens public health and jeopardizes the health of the most disadvantaged groups such as women, children, the elderly and low-income families. Economic factors play a crucial role and could affect personal nutrition status and health. Economic decision factors such as food price and income do influence people's food choices. Moreover, food costs are a barrier for low income-families to healthier food choices. Several studies indicate that diet costs are associated with dietary quality and also food safety. Food prices have surged over the past couple of years (2007-9) and raised serious concerns about food security around the world. Rising food prices are having severe impacts on population health and nutritional status. Therefore, people who change their diet pattern for economic reasons may develop a range of nutritionally-related disorders and diseases, from so-called over-nutrition to or with under-nutrition even within the one household. This is likely to increase with growing food insecurity. Presently, economics is not integrated with mainstream nutrition science or practice, other than in "home economics", but it can enable greater understanding of how socioeconomic status may interplay with human nutritional status and health and how these situations might be resolved. Collaborative, cross-disciplinary nutritional economics research should play a greater role in the prevention and management of food crises.

Gluten-free diet (GFD) is the cornerstone treatment for celiac disease (CD). GFD implies a strict and lifelong elimination from the diet of gluten, the storage protein found in wheat, barley, rye and hybrids of these grains, such as kamut and triticale. The absence of gluten in natural and processed foods, despite being the key aspect of GFD, may lead to nutritional consequences, such as deficits and imbalances. The nutritional adequacy of GFD is particularly important in children, this the age being of maximal energy and nutrient requirements for growth, development and activity. In recent years, attention has focused on the nutritional quality of gluten-free products (GFPs) available in the market. It is well recognized that GFPs are considered of lower quality and poorer nutritional value compared to the gluten-containing counterparts. The present review focuses on the nutritional adequacy of GFD at the pediatric age, with the aim being to increase awareness of the potential complications associated with this diet, to identify strategies in order to avoid them and to promote a healthier diet and lifestyle in children with CD.

Tests are being conducted on NASA's rodent Food Bar in preparation for long-term use as the rat and mouse diet aboard the International Space Station. Nutritional analyses are performed after the bars are manufactured and then repeated periodically to determine nutritional stability. The primary factors analyzed are protein, ash, fat, fiber, moisture, amino acids, fatty acids, and minerals. Nutrient levels are compared to values published in the National Research Council's dietary requirements for rodents, and also to those contained in several commonly used commercial rodent lab diets. The Food Bar is manufactured from a powdered diet to which moisture is added as it is processed through an extruder. The bars are dipped into potassium sorbate, vacuum-sealed, and irradiated. In order to determine nutrient changes during extrusion and irradiation, the powdered diet, the non-irradiated bars, and the irradiated bars are all analyzed. We have observed lower values for some nutrients (iodine, vitamin K, and iron) in the Food Bars compared with NRC requirements. Many nutrients in the Food Bars are contained at a higher level than levels in the NRC requirements. An additional factor we are investigating is the 26% moisture level in the Food Bars, which drops to about 15% within a week, compared to a stable 10% moisture in many standard lab chow diets. In addition to the nutritional analyses, the food bar is being fed to several strains of rats and mice, and feeding study and necropsy results are being observed (Barrett et al, unpublished data). Information from the nutritional analyses and from the rodent studies will enable us to recommend the formulation that will most adequately meet the rodent Food Bar requirements for long-term use aboard the Space Station.

To investigate osseointergration of titanium implants into the tibia of rabbits, which were fed a low calcium diet and irradiated. To prepare the experimental model, control group was fed a normal diet and experimental group was fed a low calcium diet for 4 weeks. And then, titanium implants were inserted into the tibia of each rabbit. Experimental group was subdivided into two groups; low calcium diet/non-irradiation group and low calcium diet/irradiation group. The low calcium diet/irradiation group was irradiated with a single absorbed dose of 15 Gy at the 5th postoperative days. On the 12th, 19th, 33rd, 47th, and 61st days after implantation(1, 2, 4, 6, and 8 weeks after irradiation), the bone formation in the bone-implant interface area was examined by light microscopy and fluorescent microscopy. 1. In the control group, there began to form woven bone in the bone-implant interface area on the 12th days after implantation. As the experimental time was going on, the amount of bone which was in contact with the implant was increased. 2. In the low calcium diet/non-irradiation group, there began to form woven bone in the bone-implant interface area on the 19th days after implantation. Although the amount of bone which was in contact with the implant was increased as the experimental time was going on, the extent of increased bone was slightly weak as compared with control group. 3. In the low calcium diet/irradiation group, there began to form woven bone incompletely in the bone-implant interface area on the 19th days after implantation, but there were vascular connective tissues in the bone- implant interface area over the entire experimental period. 4. In the control group and low calcium diet/non-irradiation group, bone labeling bands were observed on the 33rd days after implantation, which suggests that the bone formation and remodeling was in process, but interstitial bone remodeling was not observed in the low calcium diet/irradiation group.

Endothelial lipase (EL) is a key determinant in plasma high-density lipoprotein-cholesterol. However, functional roles of EL on the development of atherosclerosis have not been clarified. We investigated whether hepatic expression of EL affects plasma lipoprotein metabolism and cholesterol diet-induced atherosclerosis. We generated transgenic (Tg) rabbits expressing the human EL gene in the liver and then examined the effects of EL expression on plasma lipids and lipoproteins and compared the susceptibility of Tg rabbits with cholesterol diet-induced atherosclerosis with non-Tg littermates. On a chow diet, hepatic expression of human EL in Tg rabbits led to remarkable reductions in plasma levels of total cholesterol, phospholipids, and high-density lipoprotein-cholesterol compared with non-Tg controls. On a cholesterol-rich diet for 16 weeks, Tg rabbits exhibited significantly lower hypercholesterolemia and less atherosclerosis than non-Tg littermates. In Tg rabbits, gross lesion area of aortic atherosclerosis was reduced by 52%, and the lesions were characterized by fewer macrophages and smooth muscle cells compared with non-Tg littermates. Increased hepatic expression of EL attenuates cholesterol diet-induced hypercholesterolemia and protects against atherosclerosis. © 2017 American Heart Association, Inc.

The gluten-free diet has traditionally been accepted as a healthy diet, but there are articles advocating that it may have some nutritional deficiencies. The current study assesses whether there was any change in the contributions of calories, essential elements, proportion of fatty acids, vitamins, minerals and fiber in children who were diagnosed with celiac diseases, comparing the diet with gluten prior one year after diagnosis with the diet without gluten to the year of diagnosis. The level of clinical or analytical impact that nutritional deficits could have was also assessed. A prospective,descriptive, observational study in which information was collected from a dietary survey, anthropometric and analytical data at pre-diagnosis of celiac disease and following a gluten diet and one year after celiac disease diagnosis, under gluten-free diet. A total of 37 patients meet the study criteria. A decrease in the intake of saturated fatty acids was found, with an increase of monounsaturated fatty acids and an increase in the intake of phosphorus in the diet without gluten. A deficient intake of vitamin D was found in both diets. Clinically, at year of gluten-free diet there was an improvement in weight and size. Analytically, there was an improvement in hemoglobin, ferritin, vitamin D, and parathyroid hormone in plasma. The gluten-free diet has minimal deficiencies, similar to those present in the diet with gluten, with an improvement in the lipid profile by increasing the proportion of monounsaturated fatty acids to the detriment of saturated fatty acids.

The Mediterranean dietary pattern, through a healthy profile of fat intake, low proportion of carbohydrate, low glycemic index, high content of dietary fiber, antioxidant compounds, and anti-inflammatory effects, reduces the risk of certain pathologies, such as cancer or Cardiovascular Disease (CVD). Nutritional adequacy is the comparison between the nutrient requirement and the intake of a certain individual or population. In population groups, the prevalence of nutrient inadequacy can be assessed by the probability approach or using the Estimated Average Requirement (EAR) cut-point method. However, dietary patterns can also be used as they have moderate to good validity to assess adequate intakes of some nutrients. The objective of this study was to review the available evidence on the Nutritional Adequacy of the Mediterranean Diet. The inclusion of foods typical of the Mediterranean diet and greater adherence to this healthy pattern was related to a better nutrient profile, both in children and adults, with a lower prevalence of individuals showing inadequate intakes of micronutrients. Therefore, the Mediterranean diet could be used in public health nutrition policies in order to prevent micronutrient deficiencies in the most vulnerable population groups. PMID:24394536

The aim of the present study was to assess the food intakes and nutritional status of children with food allergies following an elimination diet. We conducted a cross sectional study including 96 children (mean age 4.7 ± 2.5 years) with food allergies and 95 paired controls (mean age 4.7 ± 2.7 years) without food allergies. Nutritional status was assessed using measurements of weight and height and Z scores for weight-for-age, height-for-age and weight-for-height. Nutrient intakes assessment was based on a 3-day diet record. Children with food allergies had weight-for-age and height-for-age Z scores lower than controls (0.1 versus 0.6 and 0.2 versus 0.8 respectively). Children with 3 or more food allergies were smaller than those with 2 or less food allergies (p = 0.04). A total of 62 children with food allergies and 52 controls completed usable diet records. Energy, protein and calcium intakes were similar in the two groups. Children with food allergies were smaller for their age than controls even when they received similar nutrient intakes. Nutritional evaluation is essential for the follow up of children with food allergies. © 2010 John Wiley & Sons A/S.

Full Text Available Aim: To analyse the influence of parents' belief in nutrition myths on the frequency of their serving certain foods to their children. Design: Cross-sectional study. Methods: Survey carried out with 297 respondents - parents of children aged 5-18 years. The data collection took place between September 2013 and December 2014. The questionnaire focussed on 14 nutrition myths related to selected foods (milk, dairy products, meat, offal, fruit, vegetables, eggs, fish, legumes, soya, and flour dishes. At the same time, the parents reported the frequency of their serving the monitored foods to their children. In the statistical analysis, Spearman's rank correlation coefficient was used. Results: For nine nutrition myths we found significant negative coefficients between a certain nutrition myth and the frequency of the serving of the food. The nutrition myths related to the consumption of fish (r = -0.328, eggs (r = -0.203, soya (r = -0.301; -0.290, offal (r = -0.155, meat (r = -0.128, milk (r = -0.272; -0.254, and fruit/vegetables (r = -0.104. Conclusion: The belief in nutrition myths appears to be a determinant modifying parental behaviour and subsequently the quality of children's diets.

The beneficial effect of Spirulina (Spirulina platensis) on tissue lipid peroxidation and oxidative DNA damage was tested in the hypercholesterolemic New Zealand White rabbit model. After hypercholesterolemia was induced by feeding a high cholesterol (0.5%) diet (HCD) for 4 weeks, then HCD supplemented with 1% or 5% Spirulina (SP1 or SP5, respectively) was provided for an additional 8 weeks. Spirulina supplementation significantly reduced the increased lipid peroxidation level in HCD-fed rabbits, and levels recovered to control values. Oxidative stress biomarkers such as glutathione, glutathione peroxidase, glutathione reductase, and glutathione S-transferase were significantly improved in the liver and red blood cells of rabbits fed SP1. Furthermore, SP5 induced antioxidant enzyme activity by 3.1-fold for glutathione, 2.5-fold for glutathione peroxidase, 2.7-fold for glutathione reductase, and 2.3-fold for glutathione S-transferase in liver, compared to the HCD group. DNA damage in lymphocytes was significantly reduced in both the SP1 and SP5 groups, based on the comet assay. Findings from the present study suggest that dietary supplementation with Spirulina may be useful to protect the cells from lipid peroxidation and oxidative DNA damage.

Full Text Available Abstract Background Vascular calcification is implicated in myocardial infarction, instability and rigidity of the aortic wall, and bioprosthetic failures. Although an increase in the calcium (Ca content in atherogenic diets has been shown to decrease atherosclerosis in rabbits, whether Ca supplementation and deficiency can affect atherosclerosis-related aortic calcification remains unknown. Results New Zealand White male rabbit littermates were fed an atherogenic diet containing 0.5% cholesterol and 2% peanut oil. The Ca content of the diet, which normally contains 1%, was adjusted to 0.5 or 3%. Segments of thoracic aortas were dissected from rabbits for histological evaluations and Ca and Pi determinations. Rabbits with calcium supplementation were maintained for 4 months, whereas those with calcium deficiency were maintained for 2 1/2 months due to severe icterus beyond this stage. The ratios of intimal to medial areas and calcified to intimal areas were used to semi-quantify lesion accumulation and calcification, respectively. Icterus was estimated from the extent of yellowing of the skin, sclera, and mucous membranes along with gross evidence of hepatic lipidosis and/or biliary obstructions. Statistical analysis of 16 matched littermates shows that Ca supplementation significantly decreased the lesions by 41% (p Conclusion Ca supplementation to an atherogenic diet inhibits atherosclerosis, aortic calcification, and icterus, whereas a Ca deficient-diet promotes them.

This study aimed to evaluate the nutrient digestibility of growing rabbits fed diets with different levels of either Leucaena leucocephala (LLM) or Moringa oleifera (MOLM) leaf meals and also to compare total collection and TiO2 marker methods for estimating digestibility. A total of 30 California growing rabbits (1.81±0.19 kg live weight on average) were randomly distributed into five experimental groups of six rabbits each and were housed in individual cages. The groups were control, 30% LLM, 40% LLM, 30% MOLM, and 40% MOLM. All groups received pelleted diets for two weeks; diets also contained 4 g/kg titanium dioxide as dietary marker. Daily feed intake was recorded during the whole experimental period and total feces were collected daily and weighed individually during four days. The results showed that there were no difference (p>0.05) in feed, dry matter (DM), organic matter (OM), crude protein (CP), digestible energy, and crude fiber (CF) intake between the control group and the other experimental groups. The apparent digestibility values of DM, OM, CP, CF, acid detergent fiber, and gross energy were the highest for control group (p = 0.001), meanwhile MOLM diets had generally higher nutrient digestibility coefficients than LLM diets. Increasing the inclusion level of leaf meal in the diet from 30% to 40% improved the digestibility of CF from 45.02% to 51.69% for LLM and from 48.11% to 55.89% for MOLM. Similar results for apparent nutrient digestibility coefficients were obtained when either total collection or indigestible marker method was used. In conclusion, the digestibility of MOLM containing diets were better than LLM diets, furthermore TiO2 as an external marker could be used as a simple, practical and reliable method to estimate nutrients digestibility in rabbit diets.

Objective To evaluate the perinatal effects of a prenatal therapy based on intra-amniotic nutritional supplementation in a rabbit model of intrauterine growth restriction (IUGR). Methods IUGR was surgically induced in pregnant rabbits at gestational day 25 by ligating 40–50% of uteroplacental vessels of each gestational sac. At the same time, modified-parenteral nutrition solution (containing glucose, amino acids and electrolytes) was injected into the amniotic sac of nearly half of the IUGR fetuses (IUGR-T group n = 106), whereas sham injections were performed in the rest of fetuses (IUGR group n = 118). A control group without IUGR induction but sham injection was also included (n = 115). Five days after the ligation procedure, a cesarean section was performed to evaluate fetal cardiac function, survival and birth weight. Results Survival was significantly improved in the IUGR fetuses that were treated with intra-amniotic nutritional supplementation as compared to non-treated IUGR animals (survival rate: controls 71% vs. IUGR 44% p = 0.003 and IUGR-T 63% vs. IUGR 44% p = 0.02), whereas, birth weight (controls mean 43g ± SD 9 vs. IUGR 36g ± SD 9 vs. IUGR-T 35g ± SD 8, p = 0.001) and fetal cardiac function were similar among the IUGR groups. Conclusion Intra-amniotic injection of a modified-parenteral nutrient solution appears to be a promising therapy for reducing mortality among IUGR. These results provide an opportunity to develop new intra-amniotic nutritional strategies to reach the fetus by bypassing the placental insufficiency. PMID:29466434

Full Text Available Insufficient supply, high prices and competition with the human food and biofuel industries means there is a continuous demand for alternative energy sources for poultry. As a result, cassava is becoming an increasingly important ingredient in poultry diets, largely due to its high availability. Efficient use of cassava products has been shown to reduce feed costs of poultry production. The utilisation of cassava is, however, limited by a number of factors, including its high fibre and low energy content and the presence of anti-nutritional factors, primarily hydrocyanic acid (HCN. With correct processing the inclusion level of cassava in poultry diets could be increased. Extensive research has been conducted on cassava products for poultry, but there is still a lack of consistency amongst the measured nutritive values for cassava and its products, hence variation exists in results from poultry studies. This paper reviews the nutrient composition of cassava products and its value as an alternative energy source in poultry diets.

Full Text Available Metabolic syndrome (MetS has become one of the main concerns for public health because of its link to cardiovascular disease. Murine models have been used to study the effect of MetS on the cardiovascular system, but they have limitations for studying cardiac electrophysiology. In contrast, the rabbit cardiac electrophysiology is similar to human, but a detailed characterization of the different components of MetS in this animal is still needed. Our objective was to develop and characterize a diet-induced experimental model of MetS that allows the study of cardiovascular remodeling and arrhythmogenesis. Male NZW rabbits were assigned to control (n = 15 or MetS group (n = 16, fed during 28 weeks with high-fat, high-sucrose diet. We measured weight, morphological characteristics, blood pressure, glycaemia, standard plasma biochemistry and the metabolomic profile at weeks 14 and 28. Liver histological changes were evaluated using hematoxylin-eosin staining. A mixed model ANOVA or unpaired t-test were used for statistical analysis (P<0.05. Weight, abdominal contour, body mass index, systolic, diastolic and mean arterial pressure increased in the MetS group at weeks 14 and 28. Glucose, triglycerides, LDL, GOT-AST, GOT/GPT, bilirubin and bile acid increased, whereas HDL decreased in the MetS group at weeks 14 and 28. We found a 40% increase in hepatocyte area and lipid vacuoles infiltration in the liver from MetS rabbits. Metabolomic analysis revealed differences in metabolites related to fatty acids, energetic metabolism and microbiota, compounds linked with cardiovascular disease. Administration of high-fat and high-sucrose diet during 28 weeks induced obesity, glucose intolerance, hypertension, non-alcoholic hepatic steatosis and metabolic alterations, thus reproducing the main clinical manifestations of the metabolic syndrome in humans. This experimental model should provide a valuable tool for studies into the mechanisms of cardiovascular

Calliandra calothyrsus Meissn is one of a highly protein source of forage, however, it is not widely used for non ruminant feed because it contains antinutritional substances in the form of condensed tannin. Tannin can bind proteins, this tannin-protein complexes are difficult to be digested in the gastrointestinal tract, then will be defecated outside the body. To optimize the utilization of calliandra in the diet, pineapple peels were added as a source of protease (bromelain). Beside of waste utilization, it is expected that bromelain can degrade the tannin-protein complexes thereby reducing the negative effects of tannins. This research is a feeding experiment on male rabbit (Lepus sp), five weeks old. The diet formulation is prepared according to the standardized diet of the local rabbit. This experiment used a Completely Randomized Design (CRD) with four treatments i.e. control group which were only given commercial feed (R0), commercial feed contained 15% of Calliandra leaf meal and 30% of pineapple peel (R1), commercial feed contained 30% of Calliandra leaf meal and 30% of pineapple peel (R2), and commercial feed contained 45% of Calliandra and 30% of pineapple peel (R3). The treatment was done for three months. The results of this study on the reproduction of male rabbits showed that the increase of calliandra leaf meal level in a diet containing 30% of pineapple peels affected the testicular histology, and also decreased the diameter of seminiferous tubule and blood testosterone levels of male rabbits.

Brassica phytochemicals exert a broad spectrum of health-promoting activities. The aim of this study was to investigate the possible beneficial effects of a cauliflower leaf powder (CLP)-enriched diet to prevent inflammation and oxidative stress resulting from injection of lipopolysaccharide (LPS) into rabbits. Animals (24 rabbits) were randomly divided into two groups and fed with a standard diet (SD) or a standard diet supplemented with a 100 g kg -1 diet of CLP. After 60 days, six rabbits of both groups received a LPS injection (100 μg per kg body weight). Serum samples collected after 90 min of LPS injection were assessed for their content of both inflammatory biomarkers such as tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and matrix-metalloproteinases (MMP-2 and MMP-9) and oxidative stress biomarkers such as thiobarbituric acid reactive substances (TBARS), glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT). LPS increased the levels of TNF-α, IL-6, and TBARS as well as MMP-2 and MMP-9 activities, whereas it decreased the GSH levels and SOD and CAT activities. In conclusion, preventive supplementation with CLP can protect rabbits from the inflammation and oxidative stress induced by LPS.
Full Text Available The rapid rise of obesity during the past decades has coincided with a profound shift of our living environment, including unhealthy dietary patterns, a sedentary lifestyle, and physical inactivity. Genetic predisposition to obesity may have interacted with such an obesogenic environment in determining the obesity epidemic. Growing studies have found that changes in adiposity and metabolic response to low-calorie weight loss diets might be modified by genetic variants related to obesity, metabolic status and preference to nutrients. This review summarized data from recent studies of gene-diet interactions, and discussed integration of research of metabolomics and gut microbiome, as well as potential application of the findings in precision nutrition.
Full Text Available This study investigated the effect of chestnut tannins on meat quality in broiler rabbits. 72 commercial hybrid rabbits (mean body weight 740 g, 32 days old were fed for 49 days with three diets containing 0%, 0.5% and 1.0% of a commercial chestnut wood extract (ENC®, Sil- vachimica srl, respectively. Eight rabbits per group were slaughtered at 12 weeks of age and at 24h post-mortem pH and colour were measured on the carcass. Moreover, both sides of m. longis- simus thoracis (LT were dissected. Left side was used for cooking losses whereas the other side was used for the determination of fatty acid profile and lipid oxidation. Data were statistically analyzed by one-way ANOVA. No differences were found in pH, colour and cooking losses, as well as the fatty acid profile of LT muscle and its relative health indexes. Concerning the antioxidant effect, the ENC shows a positive and significant effect at the inclusion level of 0.5%. In conclusion, the ENC has not undesirable side effects on the meat quality of rabbits, although further studies will be necessary to find the optimal diet inclusion level of ENC to elicit a stronger antioxidant effect in the rabbit meat.

Energy restricted meal plans may compromise nutrient intake. This study used diet modelling to assess the nutritional adequacy of energy restricted meal plans designed for weight management in young obese women. Diet modelling of 6000 kJ/d animal protein based meal plans was performed using Australian nutrient databases with adequacy compared to the Australian Nutrient Reference Values (NRVs) for women (19-30 years). One diet plan was based on the higher carbohydrate (HC) version of the Australian Guide to Healthy Eating for women 19-60 years. An alternative higher protein (HP) plan was adapted from the CSIRO Total Wellbeing Diet. Vegan and lacto-ovo versions of these plans were also modelled and compared to the appropriate vegetarian NRVs. Both animal protein diets met the estimated average requirement (EAR) or adequate intake (AI) for all nutrients analysed. The recommended dietary intake (RDI) was also satisfied, except for iron. HC met 75±30% and HP 81±31% of the iron RDI when red meat and iron fortified cereal were both included three days a week, and remained below the RDI even when red meat was increased to seven days. Iron for the modified vegan (57±5% HC; 66±4% HP) and lacto-ovo (48±6% HC; 59±7% HP) plans was below the RDI and zinc below the EAR for the vegan (76±8% HC; 84±9% HP) plans. The 6000 kJ/d animal protein meal plans met the RDI for all nutrients except iron. Iron and zinc failed to meet the vegetarian RDI and EAR respectively for the vegan plans.
Full Text Available Abstract INTRODUCTION: Atherosclerosis and cardiovascular diseases are the most common causes of death in western countries. The beneficial effect of ascorbic acid on various organs has been reported. The present study was conducted to determine the effect of ascorbic acid on the right and left coronary arteries of male rabbits fed with high-cholesterol diet. methods: Twenty white male rabbits (mean weight: 950 g were weighed and randomly divided into two groups. For 40 days, group 1 (n=10 was given a high-cholesterol (1% diet, group 2 (n=10 was fed with a high-cholesterol diet and ascorbic acid (100 mg/kg. Then both of the groups were weighed and the animals were sacrificed. The right and left coronary arteries were dissected and then fixation, tissue processing, histological sectioning and H & E staining were carried out and sections were studied by light microscopy. The results were analyzed by using the Mann Whitney test. results: Group 2 which received ascorbic acid had no fatty streaks in their coronary arteries. Significant difference in mean weight was observed before and after the diet in both groups (P<0.05. CONCLUSIONS: Histopathological study of the coronary arteries showed that the rabbits which received ascorbic acid diet did not develop fatty streaks. Thus ascorbic acid exerts an apparently inhibitory effect on fatty streak formation and may slow down or prevent atherosclerosis by countering the side effects of a high-fat meal. Keywords: Ascorbic acid, cholesterol, coronary arteries.
Full Text Available Background: A new herbal drug setarud (IMODTM containing selenium, carotene, and flavonoids, was expected to have positive effects on lipid metabolism and liver functions, due to the nature of its primary components. This study was designed to determine effectiveness of the drug in reducing the risk of development of diet-induced hypercholesterolemia in laboratory animals. Methods: Two groups of male rabbits (n=10 per group as: intact and control groups on regular chow, were fed a high-cholesterol diet, and two experimental groups were maintained on the same diet and treated with different daily doses (0.02 g/kg and 0.04 g/kg of setarud (brand name IMOD®, Pars Roos, Iran. The treatment groups were then compared with the intact and control groups and with one another for the effects of the drug which was determined by changes in blood sugar, serum lipid levels, and liver function tests. Results: Results showed that drug had important benefits in alleviating the impact of high-cholesterol diet on serum lipids and liver function markers in drug-treated groups relative to hyperlipidemic controls (p < 0.001. A more favorable modification of total cholesterol and triglyceride levels and the atherogenic index was found in animals, which received 0.04 g/kg drug, as compared to the 0.02 g/kg dose group (p < 0.05. Assessment of serum total protein, albumin, transaminases, and bilirubin levels showed that no changes in liver function of control and drug-treated animals during the period of the study. Conclusion: From the results of this study it may concluded that setarud has dose-dependent positive effects on liver and lipid metabolism and may acts as an effective anti-hyperglycemic agent.

Full Text Available To investigate the effect of low dose amlodipine v/s nifedipine on serum cholesterol profile of rabbits receiving standard diet. Methods: Fourty Newzealand rabbits were selected for the study. Their cholesterol profile was estimated at the beginning of the study. Rabbits were grouped into 4 groups receiving standard diet (control group, standard diet + vehicle propylene glycol, standard diet + nifedipine dissolved in propylene glycol and standard diet + amlodipine dissolved in propylene glycol. Along with standard diet they were treated with respective drugs for ten weeks. At the end of ten weeks serum cholesterol profile was estimated. Results: The cholesterol profile was estimated at the beginning and at the end of ten weeks. Total cholesterol in the amlodipine group decreased from 97±4.06 mg/dl to 90±4.2 mg/dl and HDL-Cholesterol increased from 32.01±4.40 mg/dl to 37±4.60 mg/dl after 10 week treatment but these changes were not significant. LDL cholesterol decreased significantly in rabbits with low dose of amlodipine from 55.42±3.32 mg/dl to 32.40±3.22 mg/dl and. In the nifedipine group there was a slight increase in total cholesterol from 102.49±5.16 mg/dl to 106±5.39 mg/dl, HDL cholesterol from 34.10±2.80 to 35.16±2.82 mg/dl and LDL cholesterol also increased from 56.20±2.20 mg/dl to 59.00±2.20 mg/dl after 10 week treatment. Conclusion: The study shows amlodipine produces favorable alterations in serum cholesterol profile

To study the effect of balanced diet on the nutrition status of primary schoolchildren in the mountain area in November 2004. All the subjects aged 7-9 years old were divided into intervention group and control group. The balanced diet was provided for the intervention group and the control group was maintained on their usual diet for 30 days in December. The anthropometric and nutritional status of the subjects were checked before and after the study. The growth and nutritional status of the intervention group improved significantly. However the unbalanced diet in the control group affects the normal growth of the children because the usual diet can not meet the nutrient requirement. The nutrition intervention can improve the growth and nutritional status of the primary schoolchildren in the mountain area.

The present study was designed to test the modulatory effect of dietary quercetin on follicle population, apoptosis, in vitro maturation rate and quality of oocytes in heat stressed female rabbits. A total of thirty-four New Zealand White heat stress (HS) exposed female rabbits were either fed with quercetin supplemented diet (QU-HS) or non-supplemented (HS) diet. Firstly, laparotomy was performed for oocyte retrieval and then, oocyte grading and COCs dimensional assessments were conducted. The A and B-grade oocytes were submitted for in vitro maturation. Thereafter, the ovaries were collected from rabbits and were processed for follicular population estimation and granulosa cells apoptosis. The results showed that follicle number, retrieved oocytes and A-grade oocytes were higher in QU-HS, comparatively. A significant difference was observed in A-grade oocytes dimensions between QU-HS and HS treatment groups. The oocyte maturation rate was same across the groups. The quercetin supplementation significantly improved primordial and antral stage follicles. A greater number of apoptotic cells were observed in primary and antral follicles in the HS group. In conclusion, the quercetin provision improves the follicular development, minimize granulosa cells apoptosis, and maintain the oocyte competence in HS rabbits. Copyright © 2017.

Despite known risks of prenatal nutritional deficiencies and studies documenting increased prevalence of poor dietary intake among nonpregnant alcohol abusers, the nutritional status of heavy drinking pregnant women remains largely unstudied. Animal models have found interactions between prenatal ethanol exposure and micronutrients, such as choline, folate, B12, and iron, and human studies have reported that lower maternal weight and body mass confer increased fetal alcohol-related risk. One hundred and twenty-three heavy drinking Cape Coloured pregnant women and 83 abstaining controls were recruited at their first antenatal clinic visit. At 3 prenatal study visits, each gravida was interviewed about alcohol, smoking, and drug use and weight, height, and arm skinfolds were measured. Dietary intakes of energy, protein, fat, and major micronutrients were assessed from three 24-hour recall interviews. The majority of women gained less than the recommended 0.42 kg/wk during pregnancy. Whereas methamphetamine use was associated with smaller biceps skinfolds, an indicator of body fat, alcohol consumption was not related to any anthropometric indicator. Alcohol was related to higher intake of phosphorus, choline, and vitamins B12 and D. Alcohol, cigarette, and methamphetamine use were related to lower vitamin C intake. Insufficient intake was reported by >85% of women for 10 of 22 key nutrients, and >50% for an additional 3 nutrients. Alcohol consumption during pregnancy was not associated with meaningful changes in diet or anthropometric measures in this population, suggesting that poor nutrition among drinkers does not confound the extensively reported effects of prenatal alcohol exposure on growth and neurobehavior. The poor gestational weight gain and high rates of insufficient intake for several nutrients in both the alcohol-exposed and control groups are also of public health importance.

Full Text Available The aim of this study was to determine the effect of the live yeast Saccharomyces cerevisiae on the growth performance, caecal ecosystem and overall health of growing rabbits. A control diet was formulated (crude protein: 15.9%; neutral detergent fibre: 31.6% and another diet obtained by supplementing the control diet with 1 g of Saccharomyces cerevisiae (6.5×109 colony-forming units per kg of diet. Ninety 35-d old rabbits were allotted into 3 groups: TT (rabbits offered the supplemented diet from 17 d of age onwards, CT (rabbits offered supplemented diet from 35 d and CC (rabbits fed non-supplemented diet. Body weight (BW and feed intake were measured weekly and mortality was controlled daily. At 35, 42 and 77 d of age, 6 rabbits from each group were slaughtered and digestive physiological traits, serum clinical chemistry parameters, fermentation traits, and the composition of caecal microbiota examined. At 42 and 56 d of age, 10 rabbits from each group were injected intraperitoneally with 100 μg/animal of ovalbumin and blood samples were collected for examination of plasma immunological parameters. Throughout the experiment (5-11 wk, weight gain and feed intake (37.8 and 112.6 g/d, on av. were not affected by yeast, except for weight gain in the first week after weaning, which was the highest in TT animals among the 3 groups (48.1 vs. 43.9 and 44.2 g/d for TT, CC and CT, respectively; P=0.012. This may be due to the increased trend in feed intake (P=0.072 in the TT group (96.4 g/d compared to the others. Mortality (5/90 was low and did not differ among the 3 groups.

To estimate the concern for a healthy diet and the nutrition knowledge of undergraduate students of a pharmacology and biochemistry program and their associations with the variables of interest. This cross-sectional study administered the Nutrition Knowledge Scale and the How is your diet? questionnaire to 381 students. The associations between concern for a healthy diet and nutrition knowledge and between these two factors and the demographic variables were measured by the chi-square test (χ2) or Fisher's exact test. The significance level was set at 5%. The mean age of the students was 20.6 (standard deviation [SD] = 2.7) years; 78.2% were female students; their mean body mass index was 22.6 (SD = 3.7) kg/m²; and 73.5% had an appropriate body mass index-related nutritional status. Most students fell within the category "pay attention to your diet" (77.1%) and "moderate nutrition knowledge" (79.7%). Concern for a healthy diet was significantly associated with program year (p = 0.024), socioeconomic class (p = 0.012), and physical activity (p Concern for a healthy diet was not associated with nutrition knowledge (p = 0.808). Physically inactive, first-year students from socioeconomic class B (US$ 1,046 - 1,872) were less concerned with a healthy diet. Such concern was not related to the students' nutrition knowledge.

To evaluate commercial complete canned cat foods according to their composition, labeling and nutritional characteristics. A total of 21 commercial complete canned compound feeds for adult cats were analyzed for crude nutrients, minerals, vitamins, selected amino acids and taurine. The analyzed parameters were compared to the internal set of standards of the European Pet Food Industry Federation (FEDIAF). The energy content was calculated and compared with the labeled recommendations regarding the amounts of diet that should be fed. Analyzed nutrients were compared with the labeled nutrients according to the regulations of the EU food and feed law (directive EU regulation 767/2009). In many cases, the labeled feeding protocols did not match the calculated daily energy requirements. In eight complete foods, the recommended daily feed amounts were underestimated and four recommendations exceeded energy requirements of adult cats. In 12 complete foods, the calcium and phosphorus contents were threefold higher than the respective requirement. In 16 of 21 complete foods, substantial discrepancies were observed between the recommendations and the analyzed trace elements. In particular, selenium contents exceeded the selenium requirement more than threefold. The vitamin, arginine and taurine contents showed no significant discrepancies to the recommendations. With respect to the labeled nutrients, there were only minor deviations from the regulations of the European law. In general, healthy adult cats are adequately supplied with energy and nutrients when feeding commercial canned complete diets for cats. In cases of body weight loss or gain, the labelled feed amounts should be questioned. The high phosphorus contents are an issue of concern, because a high phosphorus intake can potentially increase the risk for urinary stones and particularly for older cats the risk for renal insufficiency. Furthermore, it is recommended to decrease the high selenium levels by the

A major uncertainty in estimating energy budgets and population densities of extinct animals is the carrying capacity of their ecosystems, constrained by net primary productivity (NPP) and digestible energy content of that NPP. The hypothesis that increases in NPP of land plants due to elevated atmospheric CO2 contributed to the unparalleled size of the sauropods, the largest ever land animals, has recently been rejected, based on modern studies on herbivorous insects. However, the nutritional value of plants grown under elevated CO2 levels might be very different for vertebrate megaherbivores with more complex digestive systems and different protein:energy requirements than insects. Here we show that the metabolisable energy (ME) value of five species of potential dinosaur food plants does not decline consistently with increasing CO2 growth concentrations, with maxima observed at 1200 ppm CO2. Our data potentially rebut the hypothesis of constraints on herbivore diet quality in the Mesozoic due to CO2 levels.

In this study, the effects of the inclusion of artichoke bracts (AB) in rabbit diets on the carcass characteristics and rabbit meat quality were studied. A total of 120 rabbits aged 38 days were used and divided into three groups that were fed with different isonitrogenous and isocaloric diets supplemented with AB at 0%, 5% and 10%. The animals were single housed in wire cages at a temperature of 22±2°C and had free access to clean drinking water. At 96 days of age, 12 rabbits/group were slaughtered in an experimental slaughterhouse without fasting. The carcass was weighed and the weights of the skin and full gastrointestinal tract were recorded. Carcasses were chilled at +4°C for 24 h in a refrigerated room. The chilled carcass weight (CCW), dressing out percentage (CCW as percentage of slaughter weight), and the ratio of the head and liver were determined as a percentage of CCW. The reference carcass weight was also calculated. Carcasses were halved and the two longissimus dorsi (LD) muscles were excised. The left LD muscle was divided into two parts. The fore part was used to measure pH, colour and cooking losses. The hind part of the left LD was vacuum-packed, frozen at -20°C and then freeze-dried. Proximate composition, fatty-acid profile and thiobarbituric acid-reactive substances values were determined on freeze-dried samples. Results showed that carcass characteristics, LD muscle traits and its oxidative status were not affected by the AB supplementation, except for the meat ether extract content that increased from 0.68% to 0.94% on fresh matter basis with the increase of the AB supplementation (P<0.01). The α-linolenic acid proportion decreased with the increase of the AB supplementation from 3.58% to 2.59% in the LD muscle and from 4.74% to 3.62% in the perirenal fat, whereas the n-6/n-3 ratio increased significantly with increasing AB inclusion from 7.15 to 10.20 in the LD muscle and from 6.68 to 9.35 in the perirenal fat (P<0.01). Furthermore, no

Previous research has shown the beneficial effects of aqueous extract of Piper sarmentosum (P.s) on atherosclerosis. The first stage in atherosclerosis is the formation of foam cell. The aim of this study was to investigate the effect of the methanol extract of P.s on fatty streaks by calculating neointimal foam cell infiltration in rabbits fed with high cholesterol diet. Thirty six male New Zealand white rabbits were divided equally into six groups: (i) C: control group fed normal rabbit chow; (ii) CH: cholesterol diet (1 % cholesterol); (iii) PM1: 1 % cholesterol with methanol extract of P.s (62.5 mg/kg); (iv) PM2: 1 % cholesterol with methanol extract of P.s (125 mg/kg); (v) PM3: 1 % cholesterol with methanol extract of P.s (250 mg/kg); (vi) SMV group fed 1 % cholesterol supplemented with Simvistatin drug (1.2 mg/kg). All animals were treated for 10 weeks. At the end of the treatment, the rabbits were fasted and sacrificed and the aortic tissues were collected for histological studies to measure the area of the neointimal foam cell infiltration using software. The thickening of intima ratio of atherosclerosis and morphological changes by scanning electron microscope were measured. The results showed that the atherosclerotic group had significantly bigger area of fatty streak compared to the control group. The area of fatty streak in the abdominal aorta was significantly reduced in the treatment groups which were similar with the SMV group. Similarly, there was a reduction in the number of foam cell in the treatment groups compared to the atherosclerotic group as seen under scanning microscope. In conclusion, histological study demonstrated that the methanol extract of the P.s could reduce the neointimal foam cell infiltration in the lumen of the aorta and the atherosclerotic lesion.

Full Text Available Fumonisin B1-contaminated maize-based diets have been reported to be mycotoxic in animal species, yet more validated data and biomarkers are needed. In this study, Fumonisin B1 (FB1 infected yellow-maize was used to formulate Diets 1, 2 and 3, containing 1,700, 1,800 and 1,900µg FB1/kg diet, respectively. Sixty sexually matured bucks and does were used, but only the bucks were fed the FB1-contaminated diets for eight weeks. At the end of the feeding trial, the treated bucks were mated to the dry does that were fed FB1-free yellow maize-based diet. Effects on testis and live weight, feed utilisation, conception rate, embryo development and spermatozoa production per gram testis were monitored. Results indicated significant depression (P<0.05 in feed intake, from 546.77±12.09g/week in Diet 1 with the lowest FB1 concentration, to 509.84±21.98g/week in Diet 3 with the highest FB1 concentration in the diets. Weight gain was drastically reduced (P<0.05 from 34.13±9.32g/week in Diet 1 to 20.38±22.13g/week in Diet 3. Meanwhile, some of the untreated does were pregnant in all the treatments, indicating that FB1 concentration at 2.0mg/kg diet may not be spermaticidal and there were no abnormalities in the embryos. It was observed that the paired testis weight value in Diet 1 (3.06±0.31 was not significantly different (P>0.05 from that of Diet 3 (2.94±0.23. The testicular elements were distorted by the dietary FB1, but did not follow a definite pattern. Spermatozoa production per gram testis values (31.1 – 37.3 x 106 recorded were much higher than 24 x 106 for a healthy rabbit buck. Consequently, FB1 concentration < 2.0mg/kg diet may not affect the fertility potentials of bucks orally dosed for a relatively short period. This observation further elucidates earlier discoveries that FB1 is not a reproductive toxicant. Hence, the United States Food and Drug Administration proposed a guideline of 2.0mg total fumonisins/kg diet, to be adopted with

In New South Wales (NSW), a new suite of nutrition standards for menus and specifications for therapeutic diets to be used in hospitals has been developed. These standards were required to facilitate centralised menu planning and food production, with the move to management of most hospital food services by HealthShare NSW, a state-wide business unit of NSW Health. The standards also aim to improve communication between health professionals, particularly with the increasing use of computerised meal-ordering systems. Nutrition standards have been developed for adult, paediatric and mental health inpatients, and specifications for 147 different adult and paediatric therapeutic diets. There is still significant variation in the nutrition standards for nutrition and therapeutic diets in hospitals across the Australian states, and a move to a more nationally harmonised approach would be welcome. Further research is required to examine the impact of these standards on operating efficiency and patient care outcomes.
Full Text Available Early weight gain induced by high-fat diet has been identified as a predictor for cardiac disease, one of the most serious public health problems. Our goal is to study the influence of a HFD on biochemical, oxidant stress parameters, and the cardiac ultrastructure in both male and female prepubertal models. Experiments were carried on 24 prepubertal New Zealand white rabbits, randomly assigned to male and female control (MC and FC, resp. or HFD (MHFD and FHFD, resp. groups (n=6 for 3 months. Body and heart weights and some biochemical and oxidative stress parameters such as lipids, calcium, CKMB, MDA, uric acid, ascorbic acid, and AOA are evaluated in plasma and the left ventricle. Under HFD effect, plasma parameters, such as lipids (TL, PL, and LDL-C, MDA, and CK-MB, increase more significantly in male than in female groups, when AA decreases. Some cardiac parameters such as TG and UA increase, when AA and AOA decrease; these variations are more significant in FHFD. In both male and female rabbits, HFD caused changes in heart ultrastructure, junctional complexes, mitochondria size and form, and so on. Early HFD feeding induced overweight, oxidative stress, and metabolic alterations in plasma and the heart of prepubertal rabbits, whereas lipotoxicity has especially a negative impact on male plasma but affects more the female heart ultrastructure.

Assessment of the impact of dental function on diet and nutritional status requires robust methodologies and a standardised approach to increase accuracy of results and to facilitate cross study comparisons. The objectives of this paper are: to report the outcomes of a consensus workshop that critically reviewed publications reporting on dietary methodologies in relation to the impact of oral health on nutrition; to highlight future directions for research and; to make recommendations for appropriate use of methodologies for future research. Data relevant to nutrition and dental status published from 1980 to 2005 in English were presented at the consensus workshop for discussion and appraisal. Relevant papers were retrieved through PubMed. Relevant texts were obtained from the library at Newcastle University, UK. A purposive sample of original articles that illustrated the application of a range of nutritional methodologies to the study of oral health impacts was identified. Original flagship texts on nutritional methodologies were reviewed. Numerous studies have shown an association between loss of teeth and inferior diet. Further research is required to elucidate the impact of novel approaches to prosthetic rehabilitation and the impact of contemporaneous dietary and dental intervention on diet, nutritional status, disease progression and quality of life. The recommendation of the consensus workshop was that future studies should adopt a comprehensive approach to the assessment of nutrition that encompasses measurement of diet, body composition, biochemical indices of intake and levels of nutrients, and functional biomarkers of disease.
Full Text Available Introduction : Diet plays a significant role in the prevention and treatment of arterial hypertension. Appropriate diet makes it possible to maintain adequate body weight and improve biochemical blood parameters. The aim of the study was to assess nutritional status of arterial hypertension patients in terms of their diet. Material and methods: The study involved 55 patients diagnosed with arterial hypertension aged 45-70 years. Diet was evaluated using a 24-hour 7-day diet recall interview. In the course of the diet recall interview arterial pressure was measured three times at regular times, after a 15-minute rest period, and the recorded values were averaged. Nutritional status was assessed based on anthropometric measurements (height, body weight, waist circumference, hip circumference and the resulting nutrition status indexes, i.e. BMI (body mass index, WHR (waist-hip ratio as well as values of biochemical blood parameters. Conclusions : It was found that a considerable proportion of patients are overweight or obese, have an inappropriate lipid profile and elevated blood glucose levels. Daily food rations (DFR were inappropriately balanced. Daily food rations were deficient in energy, carbohydrates, dietary fibre, PUFA and folates. It was found that inadequate diet was correlated with nutritional status, lipid profile parameters and arterial blood pressure.

Rabbits are also herbivores which efficiently convert fodder to food. They are prolific and converter of plant proteins of little or no use to people as food into high-value animal protein. Rabbit meat is high in protein, low in calories and low in fat and cholesterol contents, being considered as a delicacy and a healthy food product. Feeding rabbits with concentrates is expensive and therefore in order to reduce cost of production, hence the use of rumen content in this study as alternative feedstuff without competition. A total of thirty six (36) weaner rabbits (oryctalagus cuniculus) of different body weight and age where use in this experiment to determine the effects of replacing rumen content with or without enzyme supplementation for groundnut cake. This feeding trial which lasted for 8 weeks was carried out in order to determine the replacement value of groundnut cake with rumen content with or without enzyme in the diet of weaner rabbit. A 3x2 factorial experiment was adopted such that there where three (3) replacement level of rumen content (0, 25 and 50 %) for groundnut cake by two supplemental level (no enzyme and enzyme supplement). The results showed that increased inclusion level of rumen content has significant effects (p 0.05) with weight gained value of 7.62,7.44 and 7.36 g respectively. Similarly there was a significant (p 0.05) of the treatment on urinary nitrogen. Significant (p 0.05) of the supplementation on the nitrogen intake. The interaction between the varying levels of rumen content supplementation had significant effects (p < 0.05) on the feacal nitrogen, feed intake and feed to gain ratio but no significant (p < 0.05) effects on interaction of nitrogen intake. In conclusion, since the results from this study showed no negative effects on the performance of the experimental animals, the test ingredient can be used as alternative feedstuff at a lower inclusion level so as to reduce production cost and expand

Food habit studies are among the first steps used to understand wildlife-habitat relationships. However, these studies are in themselves insufficient to understand differences in population productivity and life histories, because they do not provide a direct measure of the energetic value or nutritional composition of the complete diet. Here, we developed a dynamic model integrating food habits and nutritional information to assess nutritional parameters of brown bear (Ursus arctos) diets among three interior ecosystems of North America. Specifically, we estimate the average amount of digestible energy and protein (per kilogram fresh diet) content in the diet and across the active season by bears living in western Alberta, the Flathead River (FR) drainage of southeast British Columbia, and the Greater Yellowstone Ecosystem (GYE). As well, we estimate the proportion of energy and protein in the diet contributed by different food items, thereby highlighting important food resources in each ecosystem. Bear diets in Alberta had the lowest levels of digestible protein and energy through all seasons, which might help explain the low reproductive rates of this population. The FR diet had protein levels similar to the recent male diet in the GYE during spring, but energy levels were lower during late summer and fall. Historic and recent diets in GYE had the most energy and protein, which is consistent with their larger body sizes and higher population productivity. However, a recent decrease in consumption of trout (Oncorhynchus clarki), whitebark pine nuts (Pinus albicaulis), and ungulates, particularly elk (Cervus elaphus), in GYE bears has decreased the energy and protein content of their diet. The patterns observed suggest that bear body size and population densities are influenced by seasonal availability of protein an energy, likely due in part to nutritional influences on mass gain and reproductive success.

Full Text Available Helicobacter pylori colonizes the stomachs of greater than 50% of the world’s human population making it arguably one of the most successful bacterial pathogens. Chronic H. pylori colonization results in gastritis in nearly all patients; however in a subset of people, persistent infection with H. pylori is associated with an increased risk for more severe disease outcomes including B-cell lymphoma of mucosal-associated lymphoid tissue (MALT lymphoma and invasive adenocarcinoma. Research aimed at elucidating determinants that mediate disease progression has revealed genetic differences in both humans and H. pylori which increase the risk for developing gastric cancer. Furthermore, host diet and nutrition status have been shown to influence H. pylori-associated disease outcomes. In this review we will discuss how H. pylori is able to create a replicative niche within the hostile host environment by subverting and modifying the host-generated immune response as well as successfully competing for limited nutrients such as transition metals by deploying an arsenal of metal acquisition proteins and virulence factors. Lastly, we will discuss how micronutrient availability or alterations in the gastric microbiome may exacerbate negative disease outcomes associated with H. pylori colonization.

The objective of this research was to assess adherence to the Healthy Eating Index-2010 of mothers and their adolescents (11-14 years old) and to examine the role of the home environment as a mediator of maternal nutrition knowledge and adolescent diet quality. It is hypothesized that mothers with greater knowledge impact the diet quality of their adolescents by creation of healthier home environments. A sample of 206 mother-adolescent dyads separately completed the Multidimensional Home Environment Scale, a Food Frequency Questionnaire, and a Nutrition Knowledge Scale. Body mass index-for-age percentiles were derived from weight and height measurements obtained by researcher; diet quality was estimated via the Healthy Eating Index (HEI)-2010. Percent of maximum score on nutrition knowledge for both mothers and adolescents were poor, with lowest scores on recommendations of healthy eating and physical activity (48% and 19%, respectively). A model of maternal nutrition knowledge (independent variable) and adolescent diet quality (dependent variable) indicated that greater knowledge was associated with higher scores on total fruit (p = 0.02), whole grains (p = 0.05), seafood and plant proteins (p = 0.01), and overall diet quality (p empty calories (p = 0.01). Inclusion of the home environment as a mediator yielded significant estimates of the indirect effect (β = 0.61, 95% CI: 0.3-1.0). Within the home environment, psychological (β = 0.46), social (β = 0.23), and environmental (β = 0.65) variables were all significant mediators of nutrition knowledge on diet quality. These results emphasize the importance of maternal nutrition knowledge and the mediating effect of the home environment on the diet quality of adolescents. Copyright © 2016 Elsevier Ltd.

Full Text Available Background: The aim of the present study is to evaluate the role of flaxseed in non-alcoholic fatty liver disease, as well as on the lipid profile in rabbits submitted to hypercholesterolemic diet. Subject and Methods: 32 male rabbits, weighing approximately 1.5kg and averaging four months of age, were distributed into three groups. Group 1 received standard food plus 0.5% of cholesterol from dried egg, during 8 weeks. Group 2 obtained the same diet in the first 4 weeks, and 8mg/kg of ground flaxseed was added in the remaining weeks. Lastly, group 3 was fed with the previous group’s increased diet throughout the entire period. In the follow-up, the animals were euthanized, and liver blades were prepared to evaluate the histopathologic study. The evaluation score of NAFLD (ESN, as well as plasma levels of total cholesterol, LDLcholesterol, HDL-cholesterol, triglycerides and body weight, were all determined. Results: Increased levels of total cholesterol were obtained in both groups, with the smallest variation found in G3 (p=0.002. This variation was also found when the levels of LDLcholesterol were assessed (p=0.001. There was a reduction of triglyceride levels at the end of the study in G3 (p=0.008. A variation was noticed between the ESN groups, but the induced reduction was not statistically significant. Conclusion: Further studies are necessary, in order to elucidate the effects of flaxseed in NAFLD as well as in diseases that have risk factors for the development of the disease

'Wholesome Nutrition' is a concept of sustainable nutrition that was developed at the University of Giessen in the 1980s. In this concept, health and the ecologic, economic, social and cultural dimensions of nutrition are equally important. In 1992 at the UN-Conference on Environment and Development in Rio de Janeiro the definition of 'Sustainable Development' comprised the dimensions environment, economy and society. Additionally to these three 'classical' dimensions of sustainability, we included 'health' as the fourth dimension because nutrition has far reaching effects on human health. The fifth dimension, 'culture', became part of the sustainability dialogue since many years; the respective cultural background influences food habits. Presently, mankind has to cope with huge global challenges such as poverty and food insecurity in low-income countries as well as climate change. Therefore the objective is to identify prospects for actions to respond to these global challenges. The concept of 'Sustainable Nutrition' analyses the food supply chain at all stages from input-production and primary production to processing, distribution, preparation, consumption and waste disposal. The present analysis leads to the following seven principles: preference of plant-based foods, organic foods, regional and seasonal products, preference of minimally processed foods, Fair Trade products, resource-saving housekeeping and enjoyable eating culture. This concept is based on holistic thinking and has the potential to reduce the global challenges in the field of nutrition. Scientists, stakeholders, multipliers and consumers are asked to consider environmental, economic, social and cultural aspects in addition to the biological (health) aspects.
Full Text Available After decades-old efforts to nudge consumers towards healthier lifestyles through dietary guidelines, diet-related diseases are on the rise. In addition, a growing share of U.S. consumers proactively chooses nutritional supplements as an alternative preventative way of maintaining good health, a $25.5 billion industry in the United States. This paper investigates possible linkages between the economics of consumer supplement choices and the relationship to important dietary and health outcomes. We use National Health and Nutrition Examination Survey (NHANES data to estimate the impact of nutritional supplements intake on respondent's body weight outcomes, controlling for diet quality.: The focus of this article is to determine whether nutritional supplements takers differ from non-takers with regard to their health outcomes when controlling for differences in diet quality, based on individual Healthy Eating Index (HEI-2010 score. The analysis applies treatment effects estimators that account for the selection bias and endogeneity of self-reported behavior and diet-health outcomes. The analysis demonstrates a negative association between supplement intake and BMI but no significant effect on an individual's diet quality. Our findings suggest that individuals proactively invest into their health by taking nutritional supplements instead of improving diet quality through more nutritious food choices. Our results provide important contributions to the literature on a key food policy issue. Knowledge of the determinants of supplement demand in the context of strong diet-health trends should also be helpful to stakeholders in the U.S. produce sector in their competition over consumer market share.

Full Text Available The objective was to evaluate the effect of the interaction of diet density in the rearing phase×diet density in the reproductive phase on carcass composition, pregnancy rate, and litter performance of primiparous rabbit does. The experiment followed a 2×2×2 factorial (2 seasons, 2 diet densities in the rearing phase and 2 diet densities in reproductive phase, that is, from mating to weaning of the first litter. The reference diet (RD contained 184 g/kg of crude protein (CP, 165 g/kg of acid detergent fibre (ADF and 10.5 MJ/kg of digestible energy (DE. The low-density diet (LD had 147 g/kg of CP, 24 g/kg of ADF and 8.4 MJ/kg of DE. The treatments were applied from 70 d of age until weaning of the first litter at 35 d of age. Ninety-six females from the Botucatu Genetic Group (24 females/experimental group were mated at 142 d of age. On day 12 of gestation, 23 does were slaughtered to evaluate weights of carcass, organs and dissectible fat, and embryo implantation rate. No effects of diet density in the rearing or in the reproductive phases were detected on feed intake of does during the reproductive phase. Does fed LD during the rearing phase showed lower body weight at mating (3574±47 vs. 3866±43 g, P=0.0001 and during most of the reproductive phase, but they lost less weight in the peripartum. Perirenal fat was lighter in these does (72.8±10.0 vs. 102.1±9.6 g, P=0.048 and they showed a lower pregnancy rate (76.1 vs. 91.7%, P=0.045. The does fed RD in the reproductive phase were heavier during this phase (4055±40 g vs. 3887±41 g, P=0.0044. The does fed LD in rearing phase and RD in the reproductive phase showed larger litters at weaning, due to decreased kit mortality, than those fed RD in both phases (6.16±0.47 vs. 3.93±0.71, P=0.0361. Litters were lighter at weaning when LD was fed in the reproductive phase (3582±201 vs. 4733±187, P<0.0001. Feeding a low-density diet during the rearing phase and a reference diet during the

The objective of this study was to ascertain the knowledge of students on the composition of a healthy diet, daily nutritional requirements and the importance of regular exercise. A cross-sectional survey using a self-administered questionnaire with closed and open-ended questions to assess students 'knowledge on diet, nutrition and exercise was conducted. The study group were students of Tswaing High School in Pretoria, South Africa, who were in attendance on a particular day when the study was conducted and who consented to participate in the study Only 500 students of the school participated in the study Results showed that 77% of the students do not have adequate knowledge on diet, nutrition and exercise while 23% of the students showed satisfactory knowledge. Approximately 26% and 16% of the students reported that they participated in rigorous and moderate exercise respectively The study also showed that the majority of the students were however not engaged in physical activities. Students at Tswaing High School do not have adequate knowledge on nutrition, diet and exercise. Their views on what exercise entails were found not to be satisfactory. Programmes/ information or seminars that could assist to inform students on the importance of diet and exercise are therefore suggested.

Full Text Available ABSTRACT Objective: To assess the dietary intake and overall diet quality of female soccer players before the competitive games. Methods: This descriptive and cross-sectional study included 21 women aged 20.8±4.5 years from a professional soccer team. Their nutritional status and dietary adequacy during the training period, before competition season, were assessed. Dietary intake was assessed by three 24-hour recalls, one food frequency questionnaire, and the Healthy Eating Index, an overall diet quality index based on food group intake. Results: The athletes have shown proper nutritional status, but a diet deficient in energy due largely to low carbohydrate intake. On the other hand, the intakes of protein, fatty acids, and sodium were above the recommended intakes, even for athletes. Diet quality assessment by the Healthy Eating Index - 2010 resulted in a mean score of 54.6 points of a maximum of 100, indicating a need of improving the overall diet quality. Conclusion: The study found that the dietary patterns of female football players were both quantitatively and qualitatively inappropriate. A nutritional intervention is indicated to improve diet quality, with the inclusion of various foods, such as whole grains, fruits, vegetables, dairy products, and better protein quality, along with a reduction in saturated fats, sodium, and added sugar.

To determine the prevalence of nutrients less than or greater than accepted standards in commercially available enteral diets for cats, and to identify contamination incidence in enteral diets for cats. Prospective cross-sectional study. University teaching hospital. Seven commercial enteral diets for cats. Labels were evaluated to determine if diets were intended to be nutritionally complete and balanced. One diet under storage techniques partially representative of clinical conditions was sampled on days 0, 1, 3, 5, and 7 of storage for aerobic bacterial culture. All 7 diets were analyzed for key nutrients and results were compared to Association of American Feed Control Officials (AAFCO) Nutrient Profiles for Adult Cats for maintenance and National Research Council recommended allowance (NRC-RA). From label information, 4 diets were classified as complete and balanced and 3 diets were classified as not complete and balanced. All 7 diets had at least 1 nutrient less than the AAFCO minimums and the NRC-RA. The total number of nutrients less than AAFCO minimums ranged from 3 to 9 (median = 4), with iron, potassium, and manganese being the most common. Concentrations of some nutrients were undetectable. None of the samples tested had a positive aerobic culture at baseline (day 0) or on subsequent samples from days 1, 3, 5, and 7 under any storage condition. None of the diets analyzed met all of the minimum nutrient concentrations. While short-term feeding may not be of concern for an individual patient, clinicians should be aware of potential nutritional limitations when feeding enteral diets to ill or injured cats. © Veterinary Emergency and Critical Care Society 2015.

Nutrition is an important part of recovery for hospitalized patients. The aim of this study was to assess the nutritional adequacy of meals provided to and consumed by patients prescribed a therapeutic diet. Patients (N = 110) prescribed a therapeutic diet (texture-modified, low-fiber, oral fluid, or food allergy or intolerance diets) for medical or nutritional reasons were recruited from six wards of a tertiary hospital. Complete (24-h) dietary provisions and intakes were directly observed and analyzed for energy (kJ) and protein (g) content. A chart audit gathered demographic, clinical, and nutrition-related information to calculate each patient's disease-specific estimated energy and protein requirements. Provisions and intake were considered adequate if they met ≥75% of the patient's estimated requirements. Mean energy and protein provided to patients (5844 ± 2319 kJ, 53 ± 30 g) were significantly lower than their mean estimated requirements (8786 ± 1641 kJ, 86 ± 18 g). Consequently, mean nutrition intake (4088 ± 2423 kJ, 37 ± 28 g) were significantly lower than estimated requirements. Only 37% (41) of patients were provided with and 18% (20) consumed adequate nutrition to meet their estimated requirements. No therapeutic diet provided adequate food to meet the energy and protein requirements of all recipients. Patients on oral fluid diets had the highest estimated requirements (9497 ± 1455 kJ, 93 ± 16 g) and the lowest nutrient provision (3497 ± 1388 kJ, 25 ± 19 g) and intake (2156 ± 1394 kJ, 14 ± 14 g). Hospitalized patients prescribed therapeutic diets (particularly fluid-only diets) are at risk for malnutrition. Further research is required to determine the most effective strategies to improve nutritional provision and intake among patients prescribed therapeutic diets. Copyright © 2017 Elsevier Inc.

Insects and other invertebrates form a portion of many living and extinct primate diets. We review the nutritional profiles of insects in comparison with other dietary items, and discuss insect nutrients in relation to the nutritional needs of living primates. We find that insects are incorporated into some primate diets as staple foods whereby they are the majority of food intake. They can also be incorporated as complements to other foods in the diet, providing protein in a diet otherwise dominated by gums and/or fruits, or be incorporated as supplements to likely provide an essential nutrient that is not available in the typical diet. During times when they are very abundant, such as in insect outbreaks, insects can serve as replacements to the usual foods eaten by primates. Nutritionally, insects are high in protein and fat compared with typical dietary items like fruit and vegetation. However, insects are small in size and for larger primates (>1 kg) it is usually nutritionally profitable only to consume insects when they are available in large quantities. In small quantities, they may serve to provide important vitamins and fatty acids typically unavailable in primate diets. In a brief analysis, we found that soft-bodied insects are higher in fat though similar in chitin and protein than hard-bodied insects. In the fossil record, primates can be defined as soft- or hard-bodied insect feeders based on dental morphology. The differences in the nutritional composition of insects may have implications for understanding early primate evolution and ecology. Copyright © 2014 Elsevier Ltd. All rights reserved.

The digestive and metabolic utilization of protein (50% lactoalbumin + 50% casein) and fat (43.0% butter, 29.5% olive oil, 14.7% soy oil, 9.8% MCT and 3.0% lecithin) provided by two commercial diets used in clinical enteral nutrition (normoproteic, 16.1% protein and 20.8% fat, and hyperproteic, 23.1% protein and 14.9% fat), was studied in adult rats (mean body weight 180 g). The diet containing the greater amount of protein improved the digestive utilization of nitrogen, and although nitrogen retention was optimal, it failed to rise further when the dietary protein supply was increased. The digestive utilization of fat in both diets was excellent.

Exposure to maternal obesity or a maternal diet rich in fat during development may have adverse outcomes in offspring, such as the development of obesity and hypertension. The present study examined the effect of a maternal high-fat diet (m-HFD) on offspring blood pressure and renal sympathetic nerve activity, responses to stress, and sensitivity to central administration of leptin and ghrelin. Offspring of New Zealand white rabbits fed a 13% HFD were slightly heavier than offspring from mothers fed a 4% maternal normal fat diet (Pfat pad mass (P=0.015). Mean arterial pressure, heart rate, and renal sympathetic nerve activity at 4 months of age were 7%, 7%, and 24% greater, respectively (Pfat diet rabbits, and the renal sympathetic nerve activity response to airjet stress was enhanced in the m-HFD group. m-HFD offspring had markedly elevated pressor and renal sympathetic nerve activity responses to intracerebroventricular leptin (5-100 µg) and enhanced sympathetic responses to intracerebroventricular ghrelin (1-5 nmol). In contrast, there was resistance to the anorexic effects of intracerebroventricular leptin and less neuronal activation as detected by Fos immunohistochemistry in the arcuate (-57%; Pfat diet rabbits. We conclude that offspring from mothers consuming an HFD exhibit an adverse cardiovascular profile in adulthood because of altered central hypothalamic sensitivity to leptin and ghrelin.

in spite of the high incidence/prevalence of iron deficiency anemia (IDA) and the beneficial effects derived from the consumption of goat milk, scarce is known about the recovery of the anemia following a balanced diet accompanied by the intake of goat milk of goat. The aim of the current study is to assess, in rats with experimentally induced nutritional iron deficiency anemia, the effects of goat or cow milk-based diets, supplied during 30 days, on the recovery of the anemia and the efficiency of regeneration of the hemoglobin. 40 male Wistar albino rats newly weaned were divided at random in two experimental groups and they were fed ad libitum for 40 days with AIN-93G diet, either with normal iron content (control group, 45 mg/kg diet), or low iron content (anaemic group, 5 mg/kg diet). Samples of blood form the caudal vein were collected for the hematologic control of the anemia. Later, both experimental groups (control and iron deficient) were fed for 30 days with goat or cow milk- based diets. After finishing the experimental period and previous anesthesia the animals were withdrawn by canulation of the abdominal aorta, and the obtained blood was gathered in tubes with EDTA as anticoagulant for the later determination of hematologic parameters and the efficiency of regeneration of the hemoglobin. after the consumption of a diet with low iron content during 40 days, the rats were anaemic, with a concentration of hemoglobin, hematocrit, serum iron, mean corpuscular volume (MCV), serum ferritin and low transferrin (p hemoglobin was higher in control and anaemic rats fed goat milk-based diet in comparison with those fed cow milk-based diet (p hemoglobin, and to the best nutritive utilization of iron in the animals that consumed the goat milk-based diet thanks to the excellent nutritional characteristics of this type of milk. the consumption during 30 days of goat or cow milk-based diets favors the recovery of the iron deficiency anemia, especially with the goat
Full Text Available Two experiments were carried out in order to estimate the nutritional value and the performance of growing rabbits fed different levels of pearl millet (ADR 7010. In the digestibility trial, nutritional values of pearl millet were determined in 22 45-day-old New Zealand White rabbits, allotted in a completely randomized design, subjected to two treatments - a reference diet and a test diet with 70% of its volume composed of reference diet and 30% of pearl millet - and 11 replications. The apparent digestibility values of dry matter, crude protein, neutral detergent fiber and gross energy of the pearl millet were 88.7, 85.4, 24.4 and 75.0%, respectively. In the performance trial, 120 32-day-old New Zealand White rabbits were used. Rabbits were allotted in a completely randomized design and subjected to six treatments, with 10 replications and two animals for each experimental unit. The diets were formulated with increasing levels of pearl millet (20, 40, 60, 80 and 100%, substituting the corn in the reference diet, according to the digestible energy. No differences were observed in daily feed intake, daily weight gain, feed conversion, carcass traits and feed cost per kilogram of rabbit. Regardless of the amount of corn substituted, pearl can replace corn in diets for growing rabbits.

It is the position of the American Dietetic Association that the total diet or overall pattern of food eaten is the most important focus of a healthful eating style. All foods can fit within this pattern, if consumed in moderation with appropriate portion size and combined with regular physical activity. The American Dietetic Association strives to communicate healthful eating messages to the public that emphasize a balance of foods, rather than any one food or meal. Public policies that support the total diet approach include the Dietary Guidelines for Americans, MyPyramid, the DASH Diet (Dietary Approaches to Stop Hypertension), Dietary Reference Intakes, and nutrition labeling. The value of a food should be determined within the context of the total diet because classifying foods as "good" or "bad" may foster unhealthful eating behaviors. Alternative approaches may be necessary in some health conditions. Eating practices are dynamic and influenced by many factors, including taste and food preferences, weight concerns, physiology, lifestyle, time challenges, economics, environment, attitudes and beliefs, social/cultural influences, media, food technology, and food product safety. To increase the effectiveness of nutrition education in promoting sensible food choices, food and nutrition professionals should utilize appropriate behavioral theory and evidence-based strategies. A focus on moderation and proportionality in the context of a healthful lifestyle, rather than specific nutrients or foods, can help reduce consumer confusion. Proactive, empowering, and practical messages that emphasize the total diet approach promote positive lifestyle changes.

Maternal nutrition knowledge has frequently been identified as an important target for nutrition promotion interventions. The aim of the present study was to investigate whether maternal nutrition knowledge is more strongly associated with the mother's own diet or that of her child. Cross-sectional multivariate linear regression with interactions analyses of survey data. Socio-economically disadvantaged neighbourhoods in Victoria, Australia. Five hundred and twenty-three mothers and their children who participated in the Resilience for Eating and Physical Activity Despite Inequality (READI) study, a cross-sectional survey study conducted in 2009 among women and their children residing in socio-economically disadvantaged neighbourhoods. In adjusted models, for three (vegetable, chocolate/lollies and soft drink consumption) out of the seven dietary outcomes assessed, there was a significant association between maternal nutrition knowledge and maternal diet, whereas for the children's diets none of the seven outcomes were associated with maternal nutrition knowledge. Statistical comparison of regression coefficients showed no difference between the maternal nutrition knowledge-maternal diet association and the maternal nutrition knowledge-child diet association. Promoting maternal nutrition knowledge may represent an important avenue for improving diet in mothers from socio-economically disadvantaged neighbourhoods, but more information is needed on how and when this knowledge is translated to benefits for their children's diet.

Texture modified diet is a significant loss of the organoleptic qualities of the feed, so often associated with suboptimal intake and can increase the risk of malnutrition in people with chewing or swallowing difficulties. It is known that these diets based on traditional ground, have varying nutritional adequacy. The emergence of numerous commercial products lyophilized or ready to eat, with a wide variety of nutritional value, according to the range and recipe is concerned, represent an important step in the normalization of nutritional value and food security in people with dysphagia. This review discussed the possible advantages or disadvantages compared to traditional ground, and the possibilities of inclusion in the menu of hospitals and nursing homes.

Autism is a neurodevelopmental disorder with symptoms arising that are apparent throughout the patient's lifespan. Autism Spectrum Disorders (ASD) are characterised by impaired social and communication interactions as well as restricted, repetitive interests and behaviour. Currently in Poland, about 50 000 people suffer from autism, of which 1/5 are children. Epidemiological studies show that the incidence of autism is increasing, which may be due to the diagnostic category of ASD having been developed. Of vital importance in the treatment of autism, is early diagnosis which is conducive to more rapidly improving the quality of patients' health. It is believed that both genetic and environmental factors may affect the development of the disease. Moreover, expert opinion emphasises the importance of making an adequate diagnosis when the first symptoms of autism start appearing which can be both psychological, gastro-intestinal and metabolic ones. Conventional treatment is based on the combination of behavioural and dietary therapy together with pharmacotherapy. For example, adapting an appropriate diet could help alleviate the disease severity, as well as the psychological and gastrointestinal symptoms. Much scientific research has indicated that pathogenesis of autism may have a beginning already in foetal life. During pregnancy, specialists should take special heed of metabolic disorders, which can increase the risk ofASD in children. One of the dietician's tasks are to properly assess the nutritional status of mothers before and during pregnancy, thereby allowing changes in nutrition to be made wherever necessary in order that metabolic indicators be improved. Thus an important part of autism therapy is the improving patient's nutritional status to prevent the onset of gastrointestinal symptoms. Adopting diets and tailored to individual disease symptoms, is linked to the nutritional requirements and food preferences of the patient. Specialists also emphasise that

Full Text Available Consumption of unhealthy diets is exacerbating the burden of age-related ill health in aging populations. Such diets can program mammalian physiology to cause long-term, detrimental effects. Here, we show that, in Drosophila melanogaster, an unhealthy, high-sugar diet in early adulthood programs lifespan to curtail later-life survival despite subsequent dietary improvement. Excess dietary sugar promotes insulin-like signaling, inhibits dFOXO—the Drosophila homolog of forkhead box O (FOXO transcription factors—and represses expression of dFOXO target genes encoding epigenetic regulators. Crucially, dfoxo is required both for transcriptional changes that mark the fly’s dietary history and for nutritional programming of lifespan by excess dietary sugar, and this mechanism is conserved in Caenorhabditis elegans. Our study implicates FOXO factors, the evolutionarily conserved determinants of animal longevity, in the mechanisms of nutritional programming of animal lifespan.

It is the position of the Academy of Nutrition and Dietetics that the total diet or overall pattern of food eaten is the most important focus of healthy eating. All foods can fit within this pattern if consumed in moderation with appropriate portion size and combined with physical activity. The Academy strives to communicate healthy eating messages that emphasize a balance of food and beverages within energy needs, rather than any one food or meal. Public policies and dietary patterns that support the total diet approach include the 2010 Dietary Guidelines for Americans, DASH (Dietary Approaches to Stop Hypertension) Diet, MyPlate, Let's Move, Nutrition Facts labels, Healthy People 2020, and the Dietary Reference Intakes. In contrast to the total diet approach, classification of specific foods as good or bad is overly simplistic and can foster unhealthy eating behaviors. Alternative approaches are necessary in some situations. Eating practices are dynamic and influenced by many factors, including taste and food preferences, weight concerns, physiology, time and convenience, environment, abundance of foods, economics, media/marketing, perceived product safety, culture, and attitudes/beliefs. To increase the effectiveness of nutrition education in promoting sensible food choices, skilled food and nutrition practitioners utilize appropriate behavioral theory and evidence-based strategies. Focusing on variety, moderation, and proportionality in the context of a healthy lifestyle, rather than targeting specific nutrients or foods, can help reduce consumer confusion and prevent unnecessary reliance on supplements. Proactive, empowering, and practical messages that emphasize the total diet approach promote positive lifestyle changes. Copyright © 2013 Academy of Nutrition and Dietetics.

Impairment of growth has been reported in food-allergic children. It is not known whether this is related to the extent of food allergies. We sought to compare growth, nutritional status, and nutrient intake in children with food allergy either avoiding cow's milk or avoiding cow's milk and wheat, which are staples of the diet in young children. Infants and young children with challenge-proven allergy were recruited to this prospective study. They were strictly avoiding their allergic food triggers, either cow's milk, or cow's milk and wheat. They were counseled by a dietitian specialized in food allergies on food avoidance diets and nutritionally adequate supplementation at regular intervals. A 3-day food diary was kept. Children's height, weight, and laboratory data for nutritional parameters were monitored at 8-month intervals. A total of 18 patients avoiding milk and 28 patients avoiding milk and wheat were evaluated at an average of 12, 21, and 28 months of age. During the follow-up, the markers of nutritional status, nutrient intake or height for age, and weight for height were comparable between the two groups, although the means for anthropometric measures were below the average for age in both groups. The extent of food elimination diet has no impact on growth or nutritional status of food-allergic children, when diet is adequately supplemented. Close physician and dietitian follow-up are essential for food-allergic children when avoiding one or more foods, which are staples of the diet. © 2015 John Wiley & Sons A/S.

Background Rapid developments in technology have encouraged the use of smartphones in health promotion research and practice. Although many applications (apps) relating to diet and nutrition are available from major smartphone platforms, relatively few have been tested in research studies in order to determine their effectiveness in promoting health. Methods In this article, we summarize data on the use of smartphone applications for promoting healthy diet and nutrition based upon bibliographic searches in PubMed and CINAHL with relevant search terms pertaining to diet, nutrition, and weight loss through August 2015. Results A total of 193 articles were identified in the bibliographic searches. By screening abstracts or full-text articles, a total of three relevant qualitative studies and 9 randomized controlled trials were identified. In qualitative studies, participants preferred applications that were quick and easy to administer, and those that increase awareness of food intake and weight management. In randomized trials, the use of smartphone apps was associated with better dietary compliance for lower calorie, low fat, and high fiber foods, and higher physical activity levels (p=0.01-0.02) which resulted in more weight loss (p=0.042-<0.0001). Discussion Future studies should utilize randomized controlled trial research designs, larger sample sizes, and longer study periods to better establish the diet and nutrition intervention capabilities of smartphones. There is a need for culturally appropriate, tailored health messages to increase knowledge and awareness of health behaviors such as healthy eating. Smartphone apps are likely to be a useful and low-cost intervention for improving diet and nutrition and addressing obesity in the general population. Participants prefer applications that are quick and easy to administer and those that increase awareness of food intake and weight management. PMID:26819969

Purdue University, as well as the Johnson and Kennedy Space Centers and NASA Ames Research Center, are investigating approximately 5-10 plants that will be grown hydroponically to provide not only the energy and nutrients, but also the oxygen for humans habitating in Mars and lunar bases. The growth and nutritional status of rats fed either a control diet (adequate in all macro- and micronutrients) or a strict vegetarian diet consisting of 5 (vegan-5) or 10 (vegan-10) candidate crop species were investigated. In addition, vegan-10 diets were supplemented with mineral and/or vitamin mix at a level similar to the control diets to assess the effect of supplementation on nutrient status. The assessment of inedible plant material as an alternative food source was also investigated. Results of this study demonstrated that consumption of the vegan-10 diet significantly improved weight gain of rats compared to that for rats fed the vegan-5 diet. Mineral supplementation, at a level present in the control diet, to the vegan-10 diet improved growth and nutrient status, but growth was significantly lower compared to the control-fed rats. Inclusion of inedible plant material, high in ash content, improved some indices of nutrient status, without improving growth.

The present study investigated nutritional programming in Atlantic salmon to improve utilisation of a vegetable-based diet. At first exogenous feeding, fry were fed either a marine-based diet (Diet Mstimulus, 80% fishmeal (FM)/4% fish oil (FO)) or a vegetable-based diet (Diet Vstimulus, 10% FM/0% FO) for 3 weeks. Subsequently, all fish were then fed under the same conditions with a commercial, marine-based, diet for 15 weeks and thereafter challenged with a second V diet (Diet Vchallenge, 10% FM/0% FO) for 6 weeks. Diploid and triploid siblings were run in parallel to examine ploidy effects. Growth performance, feed intake, nutrient utilisation and intestinal morphology were monitored. Fish initially given Diet Vstimulus (V-fish) showed 24 % higher growth rate and 23 % better feed efficiency compared with M-fish when later challenged with Diet Vchallenge. There was no difference in feed intake between nutritional histories, but increased nutrient retentions highlighted the improved utilisation of a V diet in V-fish. There were generally few significant effects of nutritional history or ploidy on enteritis scores in the distal intestine after the challenge phase as only V-triploids showed a significant increase (Pnutritional programming and the ability to respond better when challenged later in life may be attributed to physiological and/or metabolic changes induced by the stimulus. This novel study showed the potential of nutritional programming to improve the use of plant raw material ingredients in feeds for Atlantic salmon.
Full Text Available Background. Nutrition is one of the most important determinants of kidney stone formation. This study was designed to evaluate lithogenic factors in diet of patients with renal calculi. Materials and methods. 40 stone-formers without metabolic disorders stimulating stone formation (e.g. hyperparatyroidism, primary hyperoxaluria were invited to the study. Antropometric measurements of nutritional status (BMI, WHR, analysis of body composition (BIA, quality and quantitative analysis of patients’ eating habits (3-day food records were conducted. Results. Half of patients were overweight or obese. Their diets contained high amounts of protein, fat, phosphorus, vitamin C and low amounts of fluid, calcium, magnesium, potassium, vitamin B6. Protein consumption was positively correlated with uric acid intake in diets (r = 0.78, and body weight with dietary fat intake (r = 0.58 and uric acid intake (r = 0.55. Conclusions. Complete treatment of nephrolithiasis should include nutritional therapy. No change in customary diets of patients with renal calculi can stimulate lithogenesis process.

A balanced diet informed by sound nutrition knowledge is key for operational readiness and the health of military personnel. Unfortunately, research suggests that military personnel have inadequate dietary intakes. This study assessed general nutrition knowledge, diet quality and their association in Australian military personnel. A convenience sample of male military personnel (n 211) including Army soldiers and officers completed a validated general nutrition knowledge questionnaire (GNKQ) and FFQ. The GNKQ assessed knowledge of dietary guidelines (Section A), sources of nutrients (Section B), choosing everyday foods (Section C) and diet-disease relationships (Section D). The Australian Recommended Food Score (ARFS) was used to assess diet quality from FFQ data. Statistical analyses included the χ 2 test, Spearman's correlation test, t test, median test, ANCOVA and ordinal logistic regression. The mean total GNKQ score was 52·7 %. Participants performed best on Section A (58·5 %) followed by Sections B (57·3 %) and C (57·0 %) and worst on Section D (31·0 %). Overall, officers scored significantly higher than soldiers (58·7 v. 51·9 %, P=0·001). Age was weakly but positively correlated with GNKQ total scores (r 0·307; Pdiet quality are recommended in this population, especially in soldiers.

The Ghanaian population suffers from a double burden of malnutrition. Cost of food is considered a barrier to achieving a health-promoting diet. Food prices were collected in major cities and in rural areas in southern Ghana. Linear programming (LP) was used to calculate nutritionally optimized diets (food baskets (FBs)) for a low-income Ghanaian family of four that fulfilled energy and nutrient recommendations in both rural and urban settings. Calculations included implementing cultural acceptability for families living in extreme and moderate poverty (food budget under USD 1.9 and 3.1 per day respectively). Energy-appropriate FBs minimized for cost, following Food Balance Sheets (FBS), lacked key micronutrients such as iodine, vitamin B12 and iron for the mothers. Nutritionally adequate FBs were achieved in all settings when optimizing for a diet cheaper than USD 3.1. However, when delimiting cost to USD 1.9 in rural areas, wild foods had to be included in order to meet nutritional adequacy. Optimization suggested to reduce roots, tubers and fruits and to increase cereals, vegetables and oil-bearing crops compared with FBS. LP is a useful tool to design culturally acceptable diets at minimum cost for low-income Ghanaian families to help advise national authorities how to overcome the double burden of malnutrition.

There has been an alarming worldwide increase of obese people in recent years. Currently, there is no consensus on whether patients that are scheduled to undergo bariatric surgery should lose weight before the intervention. The objective of this research is to analyse the influence of pre-surgery loss of weight in the nutritional parameters of patients. Fifty patients that were scheduled to undergo bariatric surgery followed a very low caloric diet during 4 weeks prior to the surgery. The nutritional parameters were analysed at 3 specific moments: before starting the diet, at the moment of surgery (when the diet was concluded) and one month after the surgery. Average values for hemoglobin, albumina and lymphocytes were kept within the range of normal values at all moments, even though the decrease of those parameters was statistically significant throughout the study (P<.05). By following the very low caloric diet, less than 9.5% of the sample suffered anaemia. Loss of weight prior to surgery does not have a significant influence in the nutritional parameters of the patient. These results would support the indication of losing weight for patients that are considered candidates for bariatric surgery. Copyright © 2014 AEC. Publicado por Elsevier España, S.L.U.

Full Text Available Abstract Patients who need prolonged domiciliary enteral nutritional therapy may benefit from handmade diets. However, the preparation of such diets might cause insecurity with regard to their nutritional composition and physical-chemical properties. Current study analyzes the osmolality and Hydrogen-Ion concentration (pH on handmade enteral diets. To this purpose, six formulas and two juices, prescribed on discharge from hospital, were analyzed physically and chemically. Osmolality and pH were respectively determined by cryoscopy and potentiometry. Most formulations were classified as isosmolar (with less than 400 mOsm/kg solvent, and only one was classified as slightly hyperosmolar, with rates ranging from 356.7 to 403.5 mOsm/kg solvent. On average, the standard formula presented higher osmolality than similar ones prepared for hyperglycemia. Among the juices, only one registered hyperosmolar concentration of 595.54 mOsm/kg solvent. All formulas presented pH rates classified as low acidity, ranging between 6.1 and 6.6, while the two juices had the lowest results, 4.73 and 4.66 each. The blend of ingredients used in handmade formulas and juices studied presented acceptable osmolality and pH rates for a safe administration and absence of gastrointestinal complications. Data showed here are consistent with an appropriate and healthy diet and contributed towards success in domiciliary enteral nutritional therapy.
Background Prices are an important determinant of food choices. Consequently, food price policies (subsidies and/or taxes) are proposed to improve the nutritional quality of diets. The aim of the present study was to explore the impact of food price policies on the expenditures and nutritional quality of the food baskets chosen by low- and medium-income households. Methods Experimental economics was used to examine two price manipulations: i) a fruit and vegetable price subsidy named “fruit and vegetables condition”; ii) a healthy-product subsidy coupled with an unhealthy-product tax named “nutrient profile condition”. The nutrient profiling system called SAIN,LIM was used. This system classifies each individual food according to its overall nutritional quality which then allows for a food item to be taxed or subsidized. Women from low- (n = 95) and medium-incomes (n = 33) selected a daily food basket, first, at current prices and then at manipulated prices. The redistributive effects of experimental conditions were assessed by comparing the extent of savings induced by subsidies and of costs generated by the tax on the two income groups. Energy density (kcal/100 g), free sugars (% energy) and the mean adequacy ratio (MAR) were used as nutritional quality indicators. Results At baseline (before price manipulations), low-income women selected less expensive and less healthy baskets than medium-income ones. After price manipulations expenditures for both income group decreased significantly, whereas, the nutritional quality improved (energy density decreased, the MAR increased). Additionally, the redistributive effects were less favourable for low-income women and their nutritional quality improvements from baseline were significantly lower. Conclusion Low-income women derived fewer financial and nutritional benefits from implemented food subsidies and taxes than medium-income women. This outcome suggests that food price policies may improve diet

The objective of the study was to assess nutritional and health status as well as nutritional knowledge in urban middle-aged Malaysian women. The impact of menopause on diet and health indices was also studied. The study included 360 disease free women, non users of HRT,aged > or =45 years with an intact uterus recruited from November 1999 to October 2001. Personal characteristics, anthropometric measurements and blood sample were acquired followed by clinical examination. Nutrient intake and nutritional knowledge was determined by a quantitative FFQ and KAP. The findings showed that urban middle-aged women, aged 51.65+/-5.40 years had energy intakes (EI) 11% below RDA, consisting of 53% carbohydrates, 15% protein and a 32% fat which declined with age. The sample which comprised of 42.5% postmenopausal women had a satisfactory diet and healthy lifestyle practices. Premenopausal women consumed more dietary fat (6%) with other aspects of diet comparable to the postmenopausal women. Iron intake was deficient in premenopausal women, amounting to 56% RDA contributing to a 26% prevalence of anaemia. Overall, calcium intake reached 440 mg daily but dairy products were not the main source. The postmenopaused had a more artherogenic lipid profile with significantly higher total cholesterol (TC) and LDL-C, but more premenopausal women were overweight/obese (49% versus 35%). EI was the strongest predictor for BMI and waist circumference (WC), with WC itself an independent predictor of fasting blood sugar and TC with BMI strongly affecting glucose tolerance. High nutritional knowledge was seen in 39% whereas 20% had poor knowledge. Newspapers and magazines, followed by the subject's social circle, were the main sources of nutritional information. Nutritional knowledge was positively associated with education, household income, vitamin/ mineral supplementation and regular physical activity but inversely related to TC. In conclusion, middle-aged urban women had an adequate diet
Accumulation of low density lipoprotein associated cholesterol in calcifying vesicle fractions correlates with intimal thickening in thoracic aortas of juvenile rabbits fed a supplemental cholesterol diet
Culley Nathan C
Full Text Available Abstract Background It has been shown that calcifying vesicles play an important role in aortic calcification and that cholesterol content in the isolated vesicle fraction is increased when rabbits are fed supplemental cholesterol diets. Whether lipoprotein-associated cholesterols and other lipids are also increased in the vesicle fraction and whether the increase correlates with atherosclerosis remain unknown. Results Fourteen juvenile male rabbits fed an atherogenic diet containing 0.5% cholesterol and 2% peanut oil for 3 months developed varying degrees of hypercholesterolemia and intimal thickening in the ascending thoracic aorta. The correlation between these two parameters was insignificant, and likely attributable to the use of small numbers of rabbits in this study. Despite this lack of correlation, we demonstrate that the accumulation of cholesterol in calcifying vesicle fractions obtained from the collagenase-digested aorta fragments correlates well with intimal thickening (r2 = 0.98, p Conclusion When limited numbers of rabbits are used, LDL-C accumulation in calcifying vesicle fractions is a better biomarker for atherosclerosis than LDL-C levels in the serum. The close association of LDL-C with calcifying vesicles may play an important role in atherosclerosis and calcification.
There is little if any evidence that nutrition during the time of tooth formation has any clinically significant effect on caries susceptibility of erupted teeth in man. Caries, erosion and demastication are not nutritional diseases. They are, however, diet-related diseases because erupted teeth are subject to local chemical and mechanical effects of the diet contacting the teeth. Caries is the result of a chronic undermining demineralisation of the teeth by organic acids that are produced by the bacteria of the dental biofilm while fermenting carbohydrates from the human diet. Dental erosion is the result of a chronic localised loss of dental hard tissue etched away from the surface by acids derived from the diet or from gastric reflux. The physicochemical grounds of de- and remineralisation of teeth are explained using detailed diagrams. Initial caries lesions without cavitation of the surface can remineralise (heal) under conditions of low cariogenic diet and good oral hygiene. However, once the surface has broken and cavitation occurred, there is no alternative to restorative dental therapy because remineralisation is no more possible.

We used scat analysis to determine diets and relative nutritional values of diets for black bears (Ursus americanus Pallas, 1780) in Rocky Mountain National Park, Colorado, from 2003 to 2006, and compared foods consumed and nutritional components to identify important sources of fecal gross energy (GE), crude fat (CF), and fecal nitrogen (FN) in annual and seasonal diets. Patterns of use of food classes followed typical seasonal patterns for bears, although use of animal matter was among the highest reported (>49% annually). Use of animal matter increased after spring, although crude protein levels in bear diets were always >25%. GE was typically lowest for grasses and other herbaceous plants and highest for ants and ungulates; FN was strongly positively related to most animal sources, but negatively correlated with vegetative matter; and CF showed the strongest positive relationship with ungulates and berries, with the latter likely influenced by the presence of seeds. Compared with historic data (1984-1991), contemporary diets included substantially greater prevalence of anthropogenic foods, which likely contributed to increases in size, condition, and productivity of the contemporary bear population. Management strategies are needed to increase quantity and quality of natural foods while minimizing dependence on anthropogenic sources.

In Germany, the "Dietary Schedule for the 1st year of life" and the "Optimised Mixed Diet" for children and adolescents serve as scientifically based and generally applicable dietary concepts throughout the period of growth and development. Vegetarian diets as the lacto-ovo-vegetarian diet (exclusion of meat, fish) and the vegan diet (exclusion of all food groups of animal origin) need to be evaluated for their potential to safely meet the high and specific requirements for growth and development. In this regard, high-quality studies are needed. In individuals on lacto-ovo-vegetarian diets, the safe supply with critical nutrients should be checked by thorough dietary history, possibly additional laboratory tests in risk situations like pregnancy, infancy and toddlerhood. Children on pure vegan diet need ongoing elaborate dietary strategies and continuous supplementation at any age, similar to nutritional management in children with metabolic disorders. A vegan diet is disadvised during all periods with intense growth and development. © Georg Thieme Verlag KG Stuttgart · New York.

The burden of non-communicable chronic disease (NCD) in India is increasing. Diet and body composition 'track' from childhood into adult life and contribute to the development of risk factors for NCD. Little is known about the diet patterns of Indian children. We aimed to identify diet patterns and study associations with body composition and socio-demographic factors in the Mysore Parthenon Study cohort. We collected anthropometric and demographic data from children aged 9.5 years (n = 538). We also administered a food frequency questionnaire and measured fasting blood concentrations of folate and vitamin B12. Using principal component analysis, we identified two diet patterns. The 'snack and fruit' pattern was characterised by frequent intakes of snacks, fruit, sweetened drinks, rice and meat dishes and leavened breads. The 'lacto-vegetarian' pattern was characterised by frequent intakes of finger millet, vegetarian rice dishes, yoghurt, vegetable dishes and infrequent meat consumption. Adherence to the 'snack and fruit' pattern was associated with season, being Muslim and urban dwelling. Adherence to the lacto-vegetarian pattern was associated with being Hindu, rural dwelling and a lower maternal body mass index. The 'snack and fruit' pattern was negatively associated with the child's adiposity. The lacto-vegetarian pattern was positively associated with blood folate concentration and negatively with vitamin B12 concentration. This study provides new information on correlates of diet patterns in Indian children and how diet relates to nutritional status. Follow-up of these children will be important to determine the role of these differences in diet in the development of risk factors for NCD including body composition. © 2013 The Authors.

Certain food groups are often rejected during chemotherapy (CT) due to the side effects of treatment, which may interfere with adequate diet and nutritional status. The aim of this study was to evaluate the treatment impact on the diet and nutritional status of women with breast cancer (BC). In this prospective longitudinal study, conducted in 2014-2015, 55 women diagnosed with BC, with a mean age 51.5±10.1 years, were followed and data were collected at three different times. Anthropometric and dietary assessments were performed, the latter by applying nine 24h dietary recalls, by using the Brazilian Healthy Eating Index Revised (BHEI-R), and calculating the prevalence of inadequacy by the EAR cut-off point method. Regarding the BHEI-R analysis, the majority of women had a "diet requires modification', both at the beginning (T0, 58.2%, n = 32) and during treatment (T1, 54.5%, n = 30). However, after the end of the CT, the greater percentage of patients (T2, 49.1%, n = 27) were classified as having an "inadequate diet", since the Total Fruit consumption as well as the Dark Green and Orange Vegetable and Legume consumption decreased significantly during treatment (p = 0.043 and p = 0.026, respectively). There was a significant reduction in the intake of macro and micronutrients, with a high prevalence of inadequacy, of up to 100%, for calcium, iron, phosphorus, magnesium, niacin, riboflavin, thiamin, vitamin B6, vitamin C and zinc. Assessment of the nutritional status indicated that 56% (n = 31) of patients were overweight at these three different times. Weight, BMI and Waist Circumference increased significantly, indicating a worse nutritional status, and there was a correlation between poor diet quality and higher values for BMI, Waist-Hip Ratio and Waist-to-Height Ratio.

Full Text Available Olive cake is one of the main agro-industrial co-products in the Mediterranean area of Spain, with high availability almost all year round. In addition, most of the product is dehydrated, which increases its interest in monogastric species such as rabbits. Nineteen samples from various Spanish oil mills using different processing methods were analysed for their chemical composition and in vitro digestibility. The average composition was [in dry matter (DM basis]: ash (9.64%, neutral detergent fibre (52.0%, acid detergent fibre (36.8%, acid detergent lignin (19.1%, crude protein (CP (11.3%, insoluble neutral (8.0% and acid detergent crude protein (5.15%, ether extract (10.9% and gross energy (21.9 MJ/kg. DM and CP in vitro digestibility were, on av., 53.4 and 41.4% respectively. High variability was observed among the samples for most of the traits studied. Fibrous fractions were highly correlated among them and negatively with ether extract content, whereas CP was little related to other feed components. A stepwise regression analysis allowed us to determine regression equations to predict DM and CP in vitro digestibilities from chemical composition (R2=0.80 and 0.91, respectively. As regards the current results, olive cake has potential use for rabbits as a source of insoluble fibre and lignin. Crude samples (not oil extracted combined with sieving to retain the smaller particles have an additional interest, because of their higher energy value and significant supply of high quality fat.

To verify acceptance of hospital diets as to the nutritional status among patients admitted to the Oncology/Hematology Unit of a tertiary care hospital. A cross-sectional study conducted among 100 patients, aged ≥ 18 years, of both genders. Body mass index and subjective global nutritional evaluation by patients were used to detect the nutritional status. The rest-ingestion index was used to evaluate diet acceptance, and the reasons for non-acceptance were identified by means of a questionnaire. Data were expressed in means and standard deviation, or medians and percentages. Comparisons were made using the Student's t test, Wilcoxon Mann-Whitney test, and Pearson's χ² test. A total of 59% of patients were males, and mean age was 51.6±13.5 years. According to the global subjective nutritional evaluation done by the patients themselves, 33% of the participants were considered malnourished and the body mass index detected 6.3% of malnutrition. The main symptoms reported were lack of appetite, xerostomia (dry mouth), constipation, dysgeusia, odor-related nausea, and early satiety. The rest-ingestion index was approximately 37% and significantly greater among the malnourished relative to the well-nourished (58.8 versus 46.4%; p=0.04). The primary reasons reported for non-acceptance of the diet offered were lack of flavor, monotonous preparations, large quantities offered, lack of appetite, and inappropriate temperature of the meal. A high the rest-ingestion index was seen among the patients with cancer, especially those who were malnourished according to the global nutritional evaluation produced by the patient.

The "Garaulet" Method (Mediterranean Diet, therapy of behavior and nutritional education), has shown to be effective in the treatment of the obesity. To evaluate and to compare the quality of the diets ingested before and during the treatment by means of Index-of-Feeding-Healthful (IAS) and its relationship with others variables. The sample was of 450 patients (383 women, 67 men), age 39.3 + 11.5 years and 31.2 + 5.3 of IMC. IAS of" before" and "during" treatment was calculated with a 24 h-recall previous to the treatment and a Seven-days-dietary-record questionnaire during treatment. The IAS consists of 10 variables that include cereal consumption, fruits, vegetables, dairy products and meats and other variables related to the nutritional guidelines for the Spanish population (SENC, 2004). Habitual dietary habits of the patients were acceptable with an IAS of 67 9 ± 13. However, lipids (43.9 ± 8.4%) and saturated fats (67.4 ± 20.1%) intakes were higher than recommended, while monounsaturated fats were lower (27.8 ± 15.1%). The IAS varied with the BMI and was significantly lower among obese subjects (65.1 ± 11.6) as compared to overweight (69.2 ± 13.9) (P IAS of 91.4 ± 9.8). IAS of the women studied was better (92.3 ± 9.0) than the one of men (86.4 ± 11.8) (P IAS (92.1 ± 9.2) during the treatment that those that did not reach it (87.9 ± 11.7) (P < 0.05). In this Spanish population, the diet studied, is useful to promote weight loss through the introduction of changes in dietary habits towards the reincorporation of the Mediterranean cultural tradition.

Interest in vegetarian diets is growing in Italy and elsewhere, as government agencies and health/nutrition organizations are emphasizing that regular consumption of plant foods may provide health benefits and help prevent certain diseases. We conducted a Pubmed search, up to September, 2015, for studies on key nutrients (proteins, vitamin B12, iron, zinc, calcium, vitamin D, and n-3 fatty acids) in vegetarian diets. From 295 eligible publications the following emerged: Vegetarians should be encouraged to supplement their diets with a reliable source of vitamin B12 (vitamin-fortified foods or supplements). Since the plant protein digestibility is lower than that of animal proteins it may be appropriate for vegetarians to consume more proteins than recommended for the general population. Vegetarians should also be encouraged to habitually consume good sources of calcium, iron and zinc - particularly vegetables that are low in oxalate and phytate (e.g. Brassicaceae), nuts and seeds, and calcium-rich mineral water. Calcium, iron, and zinc bioavailability can be improved by soaking, germination, and sour-dough leavening that lower the phytate content of pulses and cereals. Vegetarians can ensure good n-3 fatty acid status by habitually consuming good sources of a-linolenic acid (walnuts, flaxseeds, chia seeds, and their oils) and limiting linoleic acid intake (corn and sunflower oils). Well-planned vegetarian diets that include a wide variety of plant foods, and a reliable source of vitamin B12, provide adequate nutrient intake. Government agencies and health/nutrition organizations should provide more educational resources to help Italians consume nutritionally adequate vegetarian diets. Copyright © 2017.

Mental, neurological and substance-use disorders presently represent the greatest global burden of disease. Likewise, depression and other psychopathologies are elevated risk comorbidities of other health hazards, such as obesity. Nutrition has been implicated in behaviour, mood and in the pathology and treatment of mental illness. In this brief editorial, we aim to set the scale of the problem in context and overview advances and recent evidence linking nutrition to psychological outcomes. The purpose of the 2016 Nutrition Society Winter Meeting, 'Diet, nutrition and mental health and wellbeing' was to review where the evidence is strong, where there are unmet needs for research and to draw together the communities working in this area to share their findings. The papers presented demonstrated clear advancements that are being made in this field. The meeting illustrated compelling support for nutrition as a modifiable risk factor. The present research in the field and evidence presented at the 2016 Nutrition Society Winter Meeting lead us to postulate that even interventions with relatively modest effect sizes may plausibly and significantly curtail the disease burden of mental and neurological disease by food- and nutrient-based approaches.

Serious nutritional and contamination risks may be involved in the preparation of blenderized tube-feeding diets and in the handling of commercial diets. Their nutritional and microbiological quality in home settings is unknown. The objective of this study was to assess the nutritional and microbiological quality of commercial enteral and homemade blenderized whole foods diets intended to adult patients in home nutritional therapy. In a cross sectional study, 66 samples of commercial (CD) and noncommercial (NCD) enteral diets were collected at the homes of patients in home enteral nutritional therapy, 33 of each type. Commercial diets were either powder (PCD; n = 13) or liquid (LCD; n = 20). The samples were analyzed in laboratory to assess their nutritional and microbiological quality. Anthropometric data of mid upper arm circumference (MUAC) and triceps skinfold (TST) thickness were obtained from the patients' medical records. NCD presented significantly lower values for protein, fat, fiber, carbohydrate and energy while water content was significantly higher. PCD and LCD did not show any statistically significant differences between them. In the NCD, the values measured for macronutrients and energy corresponded to less than 50% of the prescribed values (except for fat). In CD, protein value was about 20% more than the prescribed value; fat and energy values corresponded to approximately 100% of the prescription, while carbohydrate corresponded to 92%. Regardless the type of the diet, prevalence of undernutrition was high in both groups though patients of the NCD presented a higher percentage. Samples of NCD complied significantly less with the microbiological standards; only 6.0% complied with the standard for coliform bacteria. Escherichia coli was detected in 10, 2, and 2 samples of NCD, PCD and LCD, respectively. Homemade blenderized enteral diets showed low values of energy and macronutrients, delivered less than 50% of the prescribed values and had

To compare diet quality scores between adult non-meat eaters and meat eaters, and to compare the consumption of diet components across quintiles of diet quality. Cross-sectional analysis. The Healthy Eating Index-2010 (HEI-2010) and Alternative Healthy Eating Index-2010 (AHEI-2010) were used to assess mean diet quality. Differences in consumption of diet components between quintiles of diet quality were tested using post hoc Wald tests and z tests. The National Health and Nutrition Examination Survey (NHANES), 2007-2012. The sample consisted of 16810 respondents aged≥18 years, including 280 individuals who reported not consuming meat, poultry, game birds or seafood on two non-consecutive days of dietary recall. Dietary data were obtained from one dietary recall per individual. Non-meat eaters had substantially greater HEI-2010 and AHEI-2010 scores than meat eaters (Pempty calories and unsaturated:saturated fatty acids. Mean consumption across AHEI-2010 quintiles demonstrated different (Pempty calories, and increased consumption of nuts and legumes, PUFA and vegetables, as a way to improve overall dietary quality.

Hemodialysis patients' ability to access food that is both compatible with a renal diet and affordable is affected by the local food environment. Comparisons of the availability and cost of food items suitable for the renal diet versus a typical unrestricted diet were completed using the standard Nutrition Environment Measures Survey and a renal diet-modified Nutrition Environment Measures Survey. Cross-sectional study. Twelve grocery stores in Northeast Ohio. Availability and cost of food items in 12 categories. The mean total number of food items available differed significantly (P ≤ .001) between the unrestricted diet (38.9 ± 4.5) and renal diet (32.2 ± 4.7). The mean total cost per serving did not differ significantly (P = 0.48) between the unrestricted diet ($5.67 ± 2.50) and renal diet ($5.76 ± 2.74). The availability of renal diet food items is significantly less than that of unrestricted diet food items, but there is no difference in the cost of items that are available in grocery stores. Further work is needed to determine how to improve the food environment for patients with chronic diseases. Copyright © 2017 National Kidney Foundation, Inc. Published by Elsevier Inc.

Human milk feeding is encouraged for all infants; however, the mammary gland depends on maternal dietary intake of vitamins A, B1, B2, B6, B12, D, docosahexaenoic acid (DHA), choline, and iodine. Nutrition support team knowledge of maternal feeding guidelines for these nutrient sources can therefore impact infant intake. We hypothesized that these key nutrients for lactation in the mother's diet would be less than the dietary guidelines in the United States. This was a secondary analysis of nutrition data collected during a randomized, controlled trial. Dietary records were analyzed from 16 mothers (13 with singleton and 3 with multiple births) completing the study. Mean dietary intakes of selected nutrients were calculated and compared with the current dietary reference intakes. Mean maternal dietary intake for singletons was significantly (P vitamin A (58%), vitamin D (44%), and choline (58%);) DHA comprised only 5% of the current expert recommendation. Based on singleton recommendations, mothers to twins consumed an adequate intake except for DHA. Women providing breast milk for singleton preterm infants did not consume dietary reference intakes for key nutrients. Twin mothers' diets were adequate except for DHA, but these guidelines are based on singleton pregnancies and remain poorly understood for twin needs. The nutrition support team can have a unique role in maternal dietary education to impact human milk nutrient delivery to the infant. © 2018 American Society for Parenteral and Enteral Nutrition.

Everyday great amounts of food are produced, processed, transported by the food industry and consumed by us and these activities have direct impact on our health and the environment. The current food system has started causing strain on the Earth's natural resources and that is why sustainable food production systems are needed. This review article discusses the need for sustainable diets by exploring the interactions between the food industry, nutrition, health and the environment, which are strongly interconnected. The most common environmental issues in the food industry are related to food processing loss, food wastage and packaging; energy efficiency; transportation of foods; water consumption and waste management. Among the foods produced and processed, meat and meat products have the greatest environmental impact followed by the dairy products. Our eating patterns impact the environment, but the environment can impact dietary choices as well. The foods and drinks we consume may also affect our health. A healthy and sustainable diet would minimise the consumption of energy-dense and highly processed and packaged foods, include less animal-derived foods and more plant-based foods and encourage people not to exceed the recommended daily energy intake. Sustainable diets contribute to food and nutrition security, have low environmental impacts and promote healthy life for present and future generations. There is an urgent need to develop and promote strategies for sustainable diets; and governments, United Nations agencies, civil society, research organisations and the food industry should work together in achieving this. © The Author(s) 2016.

To assess the results of a nutritional education programme developed by using available local resources to improve diet quality and decrease overweight and obesity prevalence among children. A longitudinal intervention study by means of nutritional education (INFADIMED) in children (aged 3-7 years) from Vilafranca del Penedès (Barcelona, Spain), recruited from preschool centres and primary schools, with an intervention or INFADIMED group (n=319; 50.2% female) and a control group (n=880; 49.8% female). Weight, height and body mass index were measured in both groups at the beginning and at the end of the programme. Adherence to the Mediterranean diet was also assessed using the KIDMED test. Consumption of fruit or juices, vegetables, yogurt and/or cheese, pasta or rice, and nuts increased, while skipping breakfast, consumption of bakery products for breakfast, and/or consumption of sweets several times per day decreased in the INFADIMED group. INFADIMED also changed, from the beginning to the end of the study, the adherence to a Mediterranean diet: high (39.2% to 70.5%), acceptable (49.2% to 28.2%), and low (11.6% to 1.3%). Approximately 2.6% of the participants in the control group and 11.3% of the participants in the INFADIMED group who were overweight and obese changed to normal weight (odds ratio: 4.08; 95% confidence interval: 2.37-7.04). INFADIMED is a nutritional education programme with benefits on both diet quality and overweight and obesity prevalence among children. Copyright © 2017 SESPAS. Publicado por Elsevier España, S.L.U.

For the majority of European adults, who neither smoke nor drink excessively, the most significant controllable risk factors affecting their long-term health are what they eat, and how physically active they are. Scientists are supposed to clarify to policy makers and health professionals the usefulness of their health messages. However, to be able to do that, a more detailed understanding is needed of the basic mechanisms behind the effects on health of diet and physical activity and, especially, the two in combination. Further, better methods for assessment of nutrition and physical activity in the population have to be developed, and more and better baseline data have to be collected. Increased and more efficient interventions are then needed. People trained and competent in the new discipline of Public Health Nutrition are required. Through the stimulating support that the European Commission, as well as other national and international partners, are presently giving to the development of Public Health Nutrition across Europe, we can hope for an increased mobility, networking and understanding between European nutrition and physical activity professionals. This will most likely result in greater and better policy making, strategy development, implementation and evaluation. We now have a great possibility to develop the integrated field of preventive nutrition and health enhancing physical activity.

Feed restriction after weaning is widely used in meat rabbit farms to promote health and reduce mortality, but this practice impacts negatively on rabbit growth and slaughter performance. This study compared a 3-week post-weaning feed restriction with ad libitum medicated feeding, evaluating effects on feed intake, growth, health, carcass and meat quality of rabbits of two genotypes: Italian White pure breed and Hycole hybrid×Italian White crossbred. A total of 512 rabbits at 36 days of age, of both sexes and two genotypes, were divided into four homogeneous groups assigned, from 36 to 57 days of age, to different feeding programmes (FP): restricted non-medicated (R-N), ad libitum non-medicated (L-N), restricted medicated (R-M) and ad libitum medicated (L-M). The diets were medicated with oxytetracycline (1540 mg/kg) and colistin sulphate (240 mg/kg). The restriction, performed by giving 70, 80 and 90 g/day of feed for the 1st, 2nd and 3rd week, was followed by ad libitum feeding in the successive 5 weeks, up to slaughter at 92 days of age. Restricted feeds were ingested at a level of 64% of the feed intake recorded in the ad libitum fed rabbits; it was significantly associated, regardless of medication and rabbit genotype, with a lower feed intake (-22 to -24 g dry matter/day) during the entire experiment, compensatory growth and a lower feed conversion ratio in the ad libitum period, and a lower final live weight (-150 g) than ad libitum feeding (Pmeat quality, except for a tendency towards a higher cooking loss and less fat; crossbred meat was higher in L* (+1.3; Pmeat. Under the conditions of this study, a 3-week restricted feeding after weaning resulted to be a suitable alternative, also for high growth potential genotypes, to the antibiotics to preserve rabbit health. The production of lighter carcasses could be compensated partly by the lower feed conversion ratio showed by restricted rabbits.

Although the positive association between pre-pregnancy overweight and obesity with excessive gestational weight gain is well known, it is not clear how pre-pregnancy weight status is associated with gestational weight gain through maternal diet during pregnancy. This study aimed to examine the relationship between pre-pregnancy weight status and diet quality and maternal nutritional biomarkers during pregnancy. Our study included 795 U.S. pregnant women from the National Health and Nutrition Examination Survey, 2003-2012. Pre-pregnancy body mass index (BMI) was calculated based on self-reported pre-pregnancy weight and height. The cutoff points of pregnancy was assessed by the Healthy Eating Index (HEI)-2010 based on a 24-h recall. Multivariable logistic regressions were used to estimate the odds ratios (OR) and 95% confidence intervals (CI). For all pregnant women included in this study, the mean HEI-2010 (±standard error of the mean (SEM)) was 50.7 (±0.9). Women with obese pre-pregnancy BMI demonstrated significantly lower HEI-2010 compared to those with underweight and normal pre-pregnancy BMI, respectively. In an unadjusted model, women with pre-pregnancy obesity BMI had increased odds for being in the lowest tertile of HEI-2010 (33.4 ± 0.5) compared to those with underweight pre-pregnancy BMI (OR 5.0; 95% CI 2.2-11.4). The inverse association between pre-pregnancy overweight and obesity status and diet quality during pregnancy persisted even after we controlled for physical activity levels (adjusted OR (AOR) 3.8; 95% CI 1.2-11.7, AOR 5.4; 95% CI 2.0-14.5, respectively). Serum folate concentration (ng/mL) was significantly higher in underweight women compared to overweight women (23.4 ± 1.7 vs. 17.0 ± 0.8, p pregnancy weight status and diet quality and maternal nutritional biomarkers during pregnancy. Poor diet quality as measured by HEI-2010 was shown among overweight and obese women. Nutrition education and interventions need to be targeted to those

The etiology of metabolic syndrome (MetS) is complex and involves the interplay between environmental, lifestyle and genetic determinants. MetS in men can be associated with a biochemical pattern of partial hypogonadotropic hypogonadism (HH). A similar pattern has been noted in both men and women with a variety of acute illnesses and chronic diseases, and there is ongoing debate regarding whether this phenomenon might adaptive (e.g. diverting resources from reproduction into survival), or maladaptive (e.g. anemia, sarcopenia, osteopenia and fatigue of androgen-deficiency amplify and widen the adverse consequences of the original disease-trigger). In women with hypothalamic amenorrhea (HA-HH secondary to chronic bioenergetic deficit from dietary restriction and/or intensive exercise), a genetic link to congenital HH (CHH) was recently established; women carrying monoallelic CHH gene mutations will typically not develop CHH, but are significantly more susceptible to HA. However, the male reproductive axis seems to be more resistant to similar environmental insults. In contrast, MetS-associated HH (mHH) is specifically a male phenomenon; the reproductive phenotype of females with MetS tending instead towards hyperandrogenism, rather than hypogonadism. The underlying pathogenic mechanisms responsible for mHH have not been clearly identified and, as yet, there has been no investigation of a potential role for CHH mutation carriage in its etiology. Over the decades, the use of either genetic- or diet-induced obesity and/or MetS animal models has greatly helped to illuminate the complex etiology of metabolic dysregulation, but the strong relationship between obesity/MetS and mHH in males has been largely neglected, with little or no information about the regulation of reproductive function by metabolic factors under conditions of bioenergetic excess. However, the pathogenic link between MetS and HH in males has been recently investigated in an animal model of high fat

Increasing consumer knowledge of the link between diet and health has raised the awareness and demand for functional food ingredients. Meat and its derivatives may be considered functional foods to the extent that they contain numerous compounds thought to be functional. This review will attempt to outline the excellent nutritional and dietetic properties of rabbit meat and offer an overview of the studies performed on the strategies adopted to improve the functional value of rabbit meat. Dietary manipulation has been seen to be very effective in increasing the levels of essential FA, EPA, DHA, CLA, branched chain FA, vitamin E, and selenium in rabbit meat. Dietary fortification with vitamin E or natural products such as oregano essential oil, chia seed oil, and Spirulina platensis microalga seem promising in improving the oxidative stability of rabbit meat while also adding functional ingredients.

Background and Objectives: Metabolic changes in postprandial stage, especially after consumption of high fat meal cause atherosclerosis and increase the risk of cardiovascular diseases. Apple cider vinegar is an acidic juice with useful medicinal effects. In this research; we investigated acute effects of apple cider vinegar intake on some of the biochemical atherosclerosis risk factors in high cholesterol fed rabbits.
Methods: Thirty two male New Zealand rabbits were randomly divided into four groups: normal diet group, high cholesterol diet group (%1cholesterol, %1 cholesterol with 5ml apple cider vinegar group, %1 cholesterol with 10ml apple cider vinegar group. The C-Reactive Protein (CRP, low density lipoprotein (LDL-C, high density lipoprotein (HDL-C, total cholesterol (TC, malondialdehyde (MDA, oxidized-LDL (OxLDL, serum glutamic pyruvic transaminase (SGPT, serum glutamic oxaloacetate transaminase (SGOT, nitrite, nitrate, glucose, fibrinogen triacylglycerol (TG, apolipoprotein A (ApoA1, apolipoprotein B (ApoB100 were all measured before the experiment and three hours after feeding with these treatment diets.
Results: In high cholesterol diet fibrinogen, nitrite, glucose, OxLDL, MDA and CRP showed a significant increase compared to normal diet. Significant differences were observed between both groups of apple cider vinegar by fibrinogen in comparison with hypercholesterolemic diet. Using 10ml apple cider vinegar with cholesterolemic diet caused a significant reduction in Ox-LDL, MDA and glucose in comparison with hypercholesterolemic diet. Moreover, the consumption of 5ml apple cider vinegar with cholesterolemic diet caused a significant decrease in LDL-C and TC compared to hypercholesterolemic diet. No significant difference was found between apple cider vinegar taking groups and

Analysis of stable carbon and nitrogen isotopes from soft or mineralized tissues is a direct and widely-used technique for modeling diets. In addition to its continued role in paleodiet analysis, stable isotope analysis is now contributing to studies of physiology, disease, and nutrition in archaeological and living human populations. In humans and other animals, dietary uptake and distribution of carbon and nitrogen among mineralized and soft tissue is carried out with varying efficiency due to factors of internal biology. Human pathophysiologies may lead to pathology-influenced isotopic fractionation that can be exploited to understand not just skeletal health and diet, but physiological health and nutrition. This study reviews examples from human biology, non-human animal ecology, biomedicine, and bioarchaeology demonstrating how stable isotope analyses are usefully applied to the study of physiological adaptation and adaptability. Suggestions are made for future directions in applying stable isotope analysis to the study of nutritional stress, disease, and growth and development in living and past human populations.

Adoption of the recommended breast-feeding and complementary feeding behaviors and access to the appropriate quality and quantity of foods are essential components of optimal nutrition for infants and young children between ages 6 and 24 mo. Iron, zinc and vitamin B-6 are deficient in complementary food diets in Bangladesh, Ghana, Guatemala, Mexico and Peru. Low intakes of iron are consistent with a high prevalence of anemia seen in this age group. The adequacy of observed intakes for calcium, vitamin A, thiamin, folate and vitamin C depends on the age range in question and the set of requirements used in the assessment. The lipid content of many complementary food diets is low. In addition to providing essential fatty acids, lipids are needed for the absorption of fat-soluble vitamins and also enhance the texture, flavor and aroma of foods, which may lead to increased intake. The relative roles of palatability, micronutrient deficiency and morbidity-induced anorexia in the appetite of infants and young children are not known. However, even among children who were growth retarded and had a total energy deficit compared with requirements, up to 25% of food offered was not consumed. This indicates that dietary quality rather than quantity is the key aspect of complementary food diets that needs to be improved. Targeted fortification or the production of complementary foods fortified with micronutrients and of an adequate macro- and micronutrient composition is one approach to help meet nutritional requirements during the vulnerable period of 6-24 mo.

of less healthy foods (sugar-sweetened beverages). Further studies are needed to test whether this conclusion holds within a more comprehensive assessment of environmental and nutritional health impacts. Conclusions This case study provides the first quantitative epidemiology-based estimate......Purpose While there has been considerable effort to understand the environmental impact of a food or diet, nutritional effects are not usually included in food-related life cycle assessment (LCA). Methods We developed a novel Combined Nutritional and Environmental Life Cycle Assessment (CONE......-LCA) framework that evaluates and compares in parallel the environmental and nutritional effects of foods or diets. We applied this framework to assess human health impacts, expressed in Disability Adjusted Life Years (DALYs), in a proof-of conceptcase study that investigated the environmental and nutritional...

Nutritional intakes of food bank recipients and consequently their health status largely rely on the availability and quality of donated food in provided food parcels. In this cross-sectional study, the nutritional quality of ninety-six individual food parcels was assessed and compared with the Dutch nutritional guidelines for a healthy diet. Furthermore, we assessed how food bank recipients use the contents of the food parcel. Therefore, 251 Dutch food bank recipients from eleven food banks throughout the Netherlands filled out a general questionnaire. The provided amounts of energy (19 849 (sd 162 615) kJ (4744 (sd 38 866) kcal)), protein (14·6 energy percentages (en%)) and SFA (12·9 en%) in a single-person food parcel for one single day were higher than the nutritional guidelines, whereas the provided amounts of fruits (97 (sd 1441) g) and fish (23 (sd 640) g) were lower. The number of days for which macronutrients, fruits, vegetables and fish were provided for a single-person food parcel ranged from 1·2 (fruits) to 11·3 (protein) d. Of the participants, only 9·5 % bought fruits and 4·6 % bought fish to supplement the food parcel, 39·4 % used all foods provided and 75·7 % were (very) satisfied with the contents of the food parcel. Our study shows that the nutritional content of food parcels provided by Dutch food banks is not in line with the nutritional guidelines. Improving the quality of the parcels is likely to positively impact the dietary intake of this vulnerable population subgroup.

A strict, lifelong gluten-free diet is the cornerstone for management of coeliac disease. Elimination of gluten from the diet may be associated with nutritional imbalance; however, the completeness of this diet in energy and macro- and micronutrients in children is not well described. Understanding the nutritional adequacy of the gluten-free diet in children during this critical period of growth and development when dietary intake is strongly influential is important. Children, regardless of whether they have eliminated gluten from their diet, have a tendency to consume excess fat and insufficient fibre, iron, vitamin D and calcium, compared to recommendations. In the context of a gluten-free diet, these imbalances may be worsened or have more significant consequences. Paediatric studies have demonstrated that intakes of folate, magnesium, zinc and selenium may decrease on a gluten-free diet. Nutritional inadequacies may be risks of a gluten-free diet in a paediatric population. The potential implications of these inadequacies, both short and long term, remain unclear and warrant further investigation and clarification.
The role of nutrition in modulating Alzheimer disease (AD) remains uncertain. Persons ingesting a Mediterranean-type diet appear to be less likely to develop AD. Epidemiologically, food combinations rich in antioxidant vitamins reduced the risk of AD. Combination formulas (eg, Souvenaid) appear to have small effects on cognition. B-vitamin supplements were mostly disappointing with inconsistent findings, except in countries where bread is not fortified with folate. They were generally negative, as were studies investigating omega-3 fatty acid supplementation. Based on this review, a Mediterranean diet and/or a combination supplement, such as Souvenaid, appear to be the most beneficial approaches with the least possible adverse effects to slowing the progression of AD.

Epidemiological evidence linking diet—one of the most important modifiable lifestyle factors—and risk of Alzheimer’s disease (AD)—the most common cause of dementia—is rapidly increasing. However, the biological mechanisms underlying the relationship between dietary nutrients, brain aging, and risk of AD are largely unexplored. Recent studies using brain imaging and biological markers of AD have begun to clarify how diet and nutrition modulate risk of AD in cognitively normal individuals, especially those at increased genetic risk. Such knowledge is critical prior to implementing dietary recommendations for prevention and treatment of disease. PMID:26167396

Diet plays an important role in preventing oral diseases including dental caries, dental erosion, developmental defects, oral mucosal diseases and, to a lesser extent, periodontal disease. This paper is intended to provide an overview of the evidence for an association between diet, nutrition and oral diseases and to clarify areas of uncertainty. Undernutrition increases the severity of oral mucosal and periodontal diseases and is a contributing factor to life-threatening noma. Undernutrition is associated with developmental defects of the enamel which increase susceptibility to dental caries. Dental erosion is perceived to be increasing. Evidence suggests that soft drinks, a major source of acids in the diet in developed countries, are a significant causative factor. Convincing evidence from experimental, animal, human observational and human intervention studies shows that sugars are the main dietary factor associated with dental caries. Despite the indisputable role of fluoride in the prevention of caries, it has not eliminated dental caries and many communities are not exposed to optimal quantities of fluoride. Controlling the intake of sugars therefore remains important for caries prevention. Research has consistently shown that when the intake of free sugars is cariogenic, this is not supported by epidemiological data, which show that high intakes of starchy staple foods, fruits and vegetables are associated with low levels of dental caries. Following global recommendations that encourage a diet high in starchy staple foods, fruit and vegetables and low in free sugars and fat will protect both oral and general health.
Background The cardiovascular and other health benefits and potential harms of protein and micronutrient deficiency of vegetarian diets continue to be debated. Methods Study participants included urban migrants, their rural siblings and urban residents (n = 6555, mean age - 40.9 yrs) of the Indian Migration Study from Lucknow, Nagpur, Hyderabad and Bangalore. Information on diet (validated interviewer-administered semi-quantitative food frequency questionnaire), tobacco, alcohol, physical activity, medical histories, as well as blood pressure, fasting blood and anthropometric measurements were collected. Nutrient databases were used to calculate nutrient content of regional recipes. Vegetarians ate no eggs, fish, poultry and meat. Using multivariate linear regression with robust standard error model, we compared the macro- and micro-nutrient profile of vegetarian and non-vegetarian diets. Results Vegetarians, (32.8% of the population), consumed greater amounts of legumes, vegetables, roots and tubers, dairy and sugar, while non-vegetarians had a greater intake of cereals, fruits, spices, salt (p Vegetarians had a higher socioeconomic status, and were less likely to smoke, drink alcohol (p vegetarians consumed more carbohydrates (β = 7.0 g/day (95% CI: 9.9 to 4.0), p vegetarian diets were found to be adequate to sustain nutritional demands according to recommended dietary allowances with less fat. Lower vitamin B12 bio-availability remains a concern and requires exploration of acceptable dietary sources for vegetarians. PMID:24899080

Full Text Available Two centuries ago Heinrich Einhof developed the so-called Weende method (crude fibre, to first deals with the fibre content of the feeds for ruminants, and proposes to isolate a residue called the "crude fibre". Then, dietary fibre concepts evolve and differ in animal feeding compared to human nutrition and health. Animal nutritionists deal with various fibre sources, often from whole plants (forages, by products of seeds processing, and recover a larger range of polysaccharidic components, including other polymers, such polyphenolic (lignins, tannins or polylipidic compounds (cutins. Dietary fibres are generally defined as polysaccharides and associated substances resistant to mammal enzyme digestion and absorption that can be partially or totally fermented in the gut. However, today this topic is still subjected to very active research, because of the complexity of the physical structure and chemical composition of the plant cell walls, and in the wide and different physiological effects of these different constituents. The importance of dietary fibre in animal feeding is due to its influence on rate of passage, mucosa functionality and its role as substrate for gut microbes performances and digestive health. This review will describe the definition and different structure of fibres and cell wall constituents and their analytical methods.
Full Text Available The aim of our study was to determine the changes in the fatty acid composition of rabbit meat, if palm fat (99% of saturated fatty acids (SFA, as a source of fat in rabbit diet, was replaced with linseed oil (71% of polyunsaturated fatty acids (PUFA, containing 52% of α-linolenic acid (n-3 PUFA. The Ganoderma lucidum or olive leaves were added in the diet as potential antioxidant in order to protect the PUFA against oxidation. 48 SIKA rabbits were randomly divided by mass and gender in four groups: CONT- 6% palm fat, CONT+ 6% linseed oil, REISHI 6% linseed oil and 1% Ganoderma lucidum, OLIVE 6% linseed oil and 1% olive leaves. After 22 days of the experimental procedure, the samples of back muscle were taken and divided in 7 portions. One was for fatty acid determination, other six for malondialdehyde (MDA determination after different storage condition; fresh, 6 days at 4°C or 3 months at -20°C, raw or cooked (60 minutes, 85°C. Addition of linseed oil resulted in a significant higher proportion of PUFA (n-3 PUFA and monounsaturated fatty acid (MUFA and lower proportion of SFA in the back muscle, but the oxidative stability of meat was reduced, since the level of MDA was significantly higher. After cooking, the level of MDA increased in all the groups, but more in the groups with linseed oil in the diet, the addition of Ganoderma lucidum or olive leaves slightly decreased the level of MDA, but the difference was not significant.

The primary aim of this study was to examine the self-reported, routine clinical practice behaviors of Australian optometrists with respect to advice regarding smoking, diet and nutritional supplementation. The study also sought to assess the potential influence of practitioner age, gender, practice location (major city versus regional), therapeutic-endorsement status and personal nutritional supplementation habits upon management practices in these areas. A survey was electronically distributed to Australian optometrists (n = 4,242). Respondents anonymously provided information about their personal demographics and lifestyle behaviors (i.e., age, gender, practice location, therapeutic-endorsement status, smoking status, nutritional supplement intake) and routine patient management practices with respect to advice across three domains: smoking, diet and nutritional supplementation. Multivariate logistic regression analyses were performed to assess for potential effects of the listed factors on practitioner behavior. A total of 283 completed surveys were received (completed survey response rate: 6.7%). Fewer than half of respondents indicated routinely asking their patients about smoking status. Younger practitioners were significantly (p smoking behaviors, but this did not extend to counseling for smoking cessation. Almost two-thirds of respondents indicated routinely counseling patients about diet. About half of practitioners specified routinely asking their patients about nutritional supplement intake; this form of questioning was significantly more likely if the respondent was female (p smoking status, diet and nutritional supplement behaviors, being key modifiable lifestyle risk factors with long-term implications for eye health.

Unhealthy eating is more prevalent among women and people with a low socioeconomic status. Policies that affect the price of food have been proposed to improve diet quality. The study's objective was to compare the impact of food price policies on the nutritional quality of food baskets chosen by low-income and medium-income women. Experimental economics was used to simulate a fruit and vegetable subsidy and a mixed policy subsidizing healthy products and taxing unhealthy ones. Food classification was based on the Score of Nutritional Adequacy of Individual Foods, Score of Nutrients to Be Limited nutrient profiling system. Low-income (n = 95) and medium-income (n = 33) women selected a daily food basket first at current prices and then at policy prices. Energy density (ED) and the mean adequacy ratio (MAR) were used as nutritional quality indicators. At baseline, low-income women selected less healthy baskets than medium-income women (less fruit and vegetables, more unhealthy products, higher ED, lower MAR). Both policies improved nutritional quality (fruit and vegetable quantities increased, ED decreased, the MAR increased), but the magnitude of the improvement was often lower among low-income women. For instance, ED decreased by 5.3% with the fruit and vegetable subsidy and by 7.3% with the mixed subsidy, whereas decreases of 13.2 and 12.6%, respectively, were recorded for the medium-income group. Finally, both policies improved dietary quality, but they increased socioeconomic inequalities in nutrition. © 2016 S. Karger AG, Basel.

15-Lipoxygenase (15-LO) has been implicated in the pathogenesis of atherosclerosis because of its localization in lesions and the many biological activities exhibited by its products. To provide further evidence for a role of 15-LO, the effects of PD 146176 on the development of atherosclerosis in cholesterol-fed rabbits were assessed. This novel drug is a specific inhibitor of the enzyme in vitro and lacks significant non specific antioxidant properties.PD 146176 inhibited rabbit reticulocyt...

To review studies examining the nutritional value of street foods and their contribution to the diet of consumers in developing countries. The electronic databases PubMed/MEDLINE, Web of Science, Cochrane Library, Proquest Health and Science Direct were searched for articles on street foods in developing countries that included findings on nutritional value. From a total of 639 articles, twenty-three studies were retained since they met the inclusion criteria. In summary, daily energy intake from street foods in adults ranged from 13 % to 50 % of energy and in children from 13 % to 40 % of energy. Although the amounts differed from place to place, even at the lowest values of the percentage of energy intake range, energy from street foods made a significant contribution to the diet. Furthermore, the majority of studies suggest that street foods contributed significantly to the daily intake of protein, often at 50 % of the RDA. The data on fat and carbohydrate intakes are of some concern because of the assumed high contribution of street foods to the total intakes of fat, trans-fat, salt and sugar in numerous studies and their possible role in the development of obesity and non-communicable diseases. Few studies have provided data on the intake of micronutrients, but these tended to be high for Fe and vitamin A while low for Ca and thiamin. Street foods make a significant contribution to energy and protein intakes of people in developing countries and their use should be encouraged if they are healthy traditional foods.

There is increasing evidence of the multiple effects of diets on public health nutrition, society, and environment. Sustainability and food security are closely interrelated. The traditional Mediterranean Diet (MD) is recognized as a healthier dietary pattern with a lower environmental impact. As a case study, the MD may guide innovative inter-sectorial efforts to counteract the degradation of ecosystems, loss of biodiversity, and homogeneity of diets due to globalization through the improvement of sustainable healthy dietary patterns. This consensus position paper defines a suite of the most appropriate nutrition and health indicators for assessing the sustainability of diets based on the MD. In 2011, an informal International Working Group from different national and international institutions was convened. Through online and face-to-face brainstorming meetings over 4 years, a set of nutrition and health indicators for sustainability was identified and refined. Thirteen nutrition indicators of sustainability relating were identified in five areas. Biochemical characteristics of food (A1. Vegetable/animal protein consumption ratios; A2. Average dietary energy adequacy; A3. Dietary Energy Density Score; A4. Nutrient density of diet), Food Quality (A5. Fruit and vegetable consumption/intakes; A6. Dietary Diversity Score), Environment (A7. Food biodiversity composition and consumption; A8. Rate of Local/regional foods and seasonality; A9. Rate of eco-friendly food production and/or consumption), Lifestyle (A10. Physical activity/physical inactivity prevalence; A11. Adherence to the Mediterranean dietary pattern), Clinical Aspects (A12. Diet-related morbidity/mortality statistics; A13. Nutritional Anthropometry). A standardized set of information was provided for each indicator: definition, methodology, background, data sources, limitations of the indicator, and references. The selection and analysis of these indicators has been performed (where possible) with

The SELEVER study is designed to evaluate the impact of an integrated agriculture-nutrition package of interventions (including poultry value chain development, women's empowerment activities, and a behavior change communications strategy to promote improved diets and feeding, care, and hygiene practices) on the diets, health, and nutritional status of women and children in Burkina Faso. This paper presents the rationale and study design. The impact evaluation involves a cluster randomized controlled trial design that will be implemented in 120 rural communities/villages within 60 communes supported by SELEVER in the Boucle de Mouhoun, Centre-Ouest, and Haut-Bassins regions of Burkina Faso. Communities will be randomly assigned to one of three treatment arms, including: (1) SELEVER intervention group; (2) SELEVER with an intensive WASH component; and (3) control group without intervention. Primary outcomes include the mean probability of adequacy of diets for women and children (aged 2-4 years at baseline), infant and young child feeding practices of caregivers of children aged 0-2 years, and household poultry production and sales. Intermediate outcomes along the agriculture and nutrition pathways will also be measured, including child nutrition status and development. The evaluation will follow a mixed-methods approach, including a panel of child-, household-, community-, and market-level surveys, and data collection points during post-harvest and lean seasons, as well as one year after implementation completion to examine sustainability. To our knowledge, this study is the first to rigorously examine from a food systems perspective, the simultaneous impact of scaling-up nutrition-specific and nutrition-sensitive interventions through a livestock value-chain and community-intervention platform, across nutrition, health, and agriculture domains. The findings of this evaluation will provide evidence to support the design of market-based nutrition
Full Text Available Maternal environment during early developmental stages plays a seminal role in the establishment of adult phenotype. Using a rabbit model, we previously showed that feeding dams with a diet supplemented with 8% fat and 0.2% cholesterol (HH diet from the prepubertal period and throughout gestation induced metabolic syndrome in adult offspring. Here, we examined the effects of the HH diet on feto-placental phenotype at 28 days post-coïtum (term = 31 days in relation to earlier effects in the blastocyst (Day 6. At 28 days, both male and female HH fetuses were intrauterine growth retarded and dyslipidemic, with males more affected than females. Lipid droplets accumulated in the HH placentas' trophoblast, consistent with the increased concentrations in cholesteryl esters (3.2-fold, triacylglycerol (2.5-fold and stored FA (2.12-fold. Stored FA concentrations were significantly higher in female compared to male HH placentas (2.18-fold, p<0.01, whereas triacylglycerol was increased only in HH males. Trophoblastic lipid droplet accumulation was also observed at the blastocyst stage. The expression of numerous genes involved in lipid pathways differed significantly according to diet both in term placenta and at the blastocyst stage. Among them, the expression of LXR-α in HH placentas was reduced in HH males but not females. These data demonstrate that maternal HH diet affects the blastocyst and induces sex-dependent metabolic adaptations in the placenta, which appears to protect female fetuses from developing severe dyslipidemia.

The activation of the sympathetic nervous system through the central actions of the adipokine leptin has been suggested as a major mechanism by which obesity contributes to the development of hypertension. However, direct evidence for elevated sympathetic activity in obesity has been limited to muscle. The present study examined the renal sympathetic nerve activity and cardiovascular effects of a high-fat diet (HFD), as well as the changes in the sensitivity to intracerebroventricular leptin. New Zealand white rabbits fed a 13.5% HFD for 4 weeks showed modest weight gain but a 2- to 3-fold greater accumulation of visceral fat compared with control rabbits. Mean arterial pressure, heart rate, and plasma norepinephrine concentration increased by 8%, 26%, and 87%, respectively (Pdiet rabbits and was correlated to plasma leptin (r=0.87; Pfat accumulation through consumption of a HFD leads to marked sympathetic activation, which is related to increased responsiveness to central sympathoexcitatory effects of leptin. The paradoxical reduction in hypothalamic neuronal activation by leptin suggests a marked "selective leptin resistance" in these animals.

The number of studies comparing nutritional quality of restrictive diets is limited. Data on vegan subjects are especially lacking. It was the aim of the present study to compare the quality and the contributing components of vegan, vegetarian, semi-vegetarian, pesco-vegetarian and omnivorous diets. Dietary intake was estimated using a cross-sectional online survey with a 52-items food frequency questionnaire (FFQ). Healthy Eating Index 2010 (HEI-2010) and the Mediterranean Diet Score (MDS) were calculated as indicators for diet quality. After analysis of the diet questionnaire and the FFQ, 1475 participants were classified as vegans (n = 104), vegetarians (n = 573), semi-vegetarians (n = 498), pesco-vegetarians (n = 145), and omnivores (n = 155). The most restricted diet, i.e., the vegan diet, had the lowest total energy intake, better fat intake profile, lowest protein and highest dietary fiber intake in contrast to the omnivorous diet. Calcium intake was lowest for the vegans and below national dietary recommendations. The vegan diet received the highest index values and the omnivorous the lowest for HEI-2010 and MDS. Typical aspects of a vegan diet (high fruit and vegetable intake, low sodium intake, and low intake of saturated fat) contributed substantially to the total score, independent of the indexing system used. The score for the more prudent diets (vegetarians, semi-vegetarians and pesco-vegetarians) differed as a function of the used indexing system but they were mostly better in terms of nutrient quality than the omnivores.

To assess the dietary habits of Balearic Islands' consumers who are successful in meeting current nutritional recommendations, to find clues for the development of future food-based dietary guidelines (FBDG) that would be relevant to this population. Cross-sectional nutritional survey carried out in the Balearic Islands between 1999 and 2000. Dietary habits were assessed by means of 24-hour recall (two non-consecutive days: warm and cold season) and a food-frequency questionnaire in a random sample (n=1200, aged 16-65 years) living in private households. Differences in percentage of compliers with the intermediate nutritional objectives for the Spanish population and differences in food consumption patterns between genders and between high (above the upper quartile of intake) and low (below the lower quartile of intake) consumers of fat, saturated fatty acids (SFA), fibre, and fruit and vegetables were analysed. Gender differences were observed in nutrient and energy intakes, as well as in attainment of the recommendations. Less than 25% of the population reached the intermediate nutritional recommendations for iodine, fruit, carbohydrates, SFA, fibre and vegetables. Low fat/SFA and high fruit and vegetables/fibre consumers kept a diet in line with the traditional Balearic diet and prevailing dietary pyramids, which ensured better compliance with the nutritional goals. The intermediate nutritional objectives for the Spanish population could be achieved through maintenance of the traditional Balearic diet, a Mediterranean-type diet in the Balearic population. Therefore, this dietary model could be used to develop FBDG relevant to this population.

To determine diet and nutrition practices and the economic and social situation in homes with premature infants. A descriptive cross-sectional study of 100 preterm infants 30 to 36 weeks gestational age, using data obtained on weight, length and head circumference at birth, and whether they were from rural or urban communities. The mothers of premature infants were given a questionnaire to find out the diet and nutrition status, and the economic and social situation in the families. The preterm infants were recruited from Maternal and Child Hospital of Leon, Guanajuato. The mean gestational age was 34 weeks (26 to 36). The mean weight, length, and head circumference at birth were: 2,007 g (659 to 3,750 g), 43.7 cm (30 to 52 cm) and 32.4 cm (28 to 35.5 cm), respectively. Almost all mothers (98%) wished to breastfeed. More than a quarter (26%) of mothers consumed soda drinks twice a week, and preferred processed food instead of preparing it at home. Fresh fruit was consumed on seven, four, and three days per week by 43%, 13%, and 21% of mothers, respectively. These amounts were similar for vegetables, legumes and cereals. Almost all (91%) referred to consuming tortillas every day. The average monthly income was 1,000 to 4,000 pesos (62.5-250 €) in most cases. Drinking water and electricity services were scarce. Most patients did not have drinking water or electricity services, as well as being on a low income. Diets were inadequate both in quality and type of food. The accessibility to foods was limited. These situations will have an impact on the growth and development of preterm infants. Copyright © 2011 Asociación Española de Pediatría. Published by Elsevier España. All rights reserved.

Full Text Available Objectives. The goal of this study is to describe modifiable lifestyle variables associated with reduced rate of Parkinson’s disease (PD progression. Methods. The patient-reported outcomes in PD (PRO-PD were used as the primary outcome measure, and a food frequency questionnaire (FFQ was used to assess dietary intake. In this cross-sectional analysis, regression analysis was performed on baseline data to identify the nutritional and pharmacological interventions associated with the rate of PD progression. All analyses were adjusted for age, gender, and years since diagnosis. Results. 1053 individuals with self-reported idiopathic PD were available for analysis. Foods associated with the reduced rate of PD progression included fresh vegetables, fresh fruit, nuts and seeds, nonfried fish, olive oil, wine, coconut oil, fresh herbs, and spices (P<0.05. Foods associated with more rapid PD progression include canned fruits and vegetables, diet and nondiet soda, fried foods, beef, ice cream, yogurt, and cheese (P<0.05. Nutritional supplements coenzyme Q10 and fish oil were associated with reduced PD progression (P=0.026 and P=0.019, resp., and iron supplementation was associated with faster progression (P=0.022.

Earlier studies have documented high prevalence of undernutrition, morbidity and mortality among Chenchus, a tribal population in Telangana and Andhra Pradesh, India. The present study was carried out to assess diet and nutritional status of Chenchus and cause of death. A total of 42 Chenchu villages (gudems) were covered using systematic random sampling procedure. In each gudem, all the households with at least one child under the age of five years were covered for various investigations. Weighment diet survey was carried out on a sub-sample of households. In addition, information on cause of death in the selected 42 gudems was collected for past one year using verbal autopsy method. A total of 1396 subjects of all age groups were covered for various investigations. The intakes of food and nutrients were lower than the recommended levels. The prevalences of underweight, stunting and wasting among under five children were 42 per cent (CI: 37.9-46.1), 53 and 13 per cent, respectively, while 41 per cent (CI: 37.8-47.2) men and 42 per cent (34.4-47.8) women had chronic energy deficiency (BMIpopulation was comparable with other tribal and rural counterparts in Andhra Pradesh, however, the crude death rate (11.7/1000) was higher among the Chenchus. Steps may be taken to promote consumption of balanced diet and utilization of optimal healthcare facilities to control morbidity and mortality.
The media are one of the main arenas in which nutrition information is framed and developed. Research has shown a predominantly individualistic framing of diet-related health issues such as obesity, type-2 diabetes and coronary heart disease in international media coverage. These issues are framed as personal, 'lifestyle' issues rather than requiring policy or structural change. In addition, research has shown a tendency in nutrition research and media coverage of it, to emphasize individual ...

Previous studies have suggested that intermittent exposure to hydrogenated vegetable shortening yields a binge/compensate pattern of feeding in rats. The present study was designed to assess whether rats would exhibit similar patterns of intake when given intermittent access to a nutritionally complete high-fat diet. Four groups of rats received varying exposure to either hydrogenated vegetable shortening or high-fat diet for 8 consecutive weeks. Animals were given daily and intermittent acce...

Full Text Available Background: There is increasing evidence of the multiple effects of diets on public health nutrition, society and environment. Sustainability and food security are closely inter-related. The traditional Mediterranean Diet (MD is recognized as a healthier dietary pattern with a lower environmental impact. As a case study, the MD may guide innovative inter-sectorial efforts to counteract the degradation of ecosystems, loss of biodiversity and homogeneity of diets due to globalization, through the improvement of sustainable healthy dietary patterns.This consensus position paper defines a suite of the most appropriate nutrition and health indicators for assessing the sustainability of diets based on the MD.Methods: In 2011, an informal International Working Group from different national and international institutions was convened. Through online and face-to-face brainstorming meetings over four years, a set of nutrition and health indicators for sustainability was identified and refined.Results: Thirteen nutrition indicators of sustainability relating were identified in five areas: •Biochemical characteristics of food (A1. Vegetable/animal protein consumption ratios; (A2. Average dietary energy adequacy; (A3. Dietary energy density score; (A4. Nutrient density of diet: •Food Quality (A5. Fruit and vegetable consumption/intakes; (A6. Dietary diversity score: •Environment (A7. Food biodiversity composition and consumption; (A8. Rate of Local/regional foods and seasonality; (A9. Rate of eco-friendly food production and/or consumption: •Lifestyle (A10. Physical activity/Physical inactivity prevalence; (A11.

In recent years, obesity has become a serious public health crisis in the United States. Although the problem of obesity is being addressed through a variety of strategies, the use of mobile apps is a relatively new development that could prove useful in helping people to develop healthy dietary habits. Though such apps might lead to health behavior change, especially when relevant behavior change theory constructs are integrated into them, the mechanisms by which these apps facilitate behavior change are largely unknown. The purpose of this study was to identify which behavior change mechanisms are associated with the use of diet- and nutrition-related health apps and whether the use of diet- and nutrition-related apps is associated with health behavior change. A cross-sectional survey was administered to a total of 217 participants. Participants responded to questions on demographics, use of diet and nutrition apps in the past 6 months, engagement and likability of apps, and changes in the participant's dietary behaviors. Regression analysis was used to identify factors associated with reported changes in theory and separately for reported changes in actual behavior, after controlling for potential confounding variables. The majority of study participants agreed or strongly agreed with statements regarding app use increasing their motivation to eat a healthy diet, improving their self-efficacy, and increasing their desire to set and achieve health diet goals. Additionally, majority of participants strongly agreed that using diet/nutrition apps led to changes in their behavior, namely increases in actual goal setting to eat a healthy diet (58.5%, 127/217), increases in their frequency of eating healthy foods (57.6%, 125/217), and increases in their consistency of eating healthy foods (54.4%, 118/217). Participants also responded favorably to questions related to engagement and likability of diet/nutrition apps. A number of predictors were also positively

Sugar content in foods cannot be distinguished from added sugar, although it is true that this added sugar brings mainly energy and no other essential nutrients. On the other hand, in the context of diet, sugar helps make it more varied and palatable allowing including foods that may otherwise not be would consume, thus indirectly contributing to the intake of other nutrients. Having interest in knowing the possible relationship between a high intake of sugars and the decrease in micronutrients intake, we noted that the nutrient density of the diet might be influenced by factors such as the high presence of sugar added to food. It seems that this nutritional dilution produced by adding sugar to food is, in general, not very significant and, often, offset by the fortification in micronutrients that we usually can find in many sugary products. After a detailed analysis of the published studies on the subject, it has been found that there is no a clear evidence of the hypothetical micronutrient dilution that would occur by adding sugar to the diet. On the other hand, given that the addition of sugar to the diet doesn't seem to report any remarkable advantages from the point of view of the intake of micronutrients; It seems reasonable to promote a moderate consumption of foods and sugary drinks, so in that way, they become an important extra energy source. It should also be borne in mind that the addition of sugar to the diet does not seem remarkable report any advantage in terms of intake of micronutrients. For this reason, it seems logical that the consumption of sugary food and sweet drinks will be moderate given the ease of consumption and the likelihood of their becoming a major source of energy. Finally, it is concluded on the need for further research on the mechanisms underlying that, up to now showed no, possible displacement of micro-nutrients and other food components of the diet that could occur in cases of consumption of foods with a high sugar content, as
Full Text Available The influence of substrate pre-digestion and donors’ diet on in vitro caecal fermentation of different substrates in rabbits was investigated. Eight crossbreed rabbits were fed 2 experimental diets containing either low (LSF; 84.0 g/kg dry matter [DM] or high soluble fibre (HSF; 130 g/kg DM levels. In vitro incubations were conducted using batch cultures with soft faeces as inoculum and four fibrous or fibre-derived, low-starch and low-protein substrates: D-cellobiose (CEL, sugar beet pectin (PEC, sugar beet pulp (SBP and wheat straw (WS. Substrates in half of the cultures were subjected to a 2-step pepsin/pancreatin in vitro digestion without filtration, and the whole residue (soluble, insoluble and added enzymes was incubated at 39°C. Gas production was measured until 144 h, and volatile fatty acid (VFA production at 24 h incubation was determined. Cultures without substrate (blanks were included to correct gas production values for gas released from endogenous substrates and added enzymes. Pre-digestion had no influence on in vitro gas production kinetic of WS, and only reduced the time before gas production begins (lag time; by 31%; P=0.042 for SBP, but for both substrates the pre-digestion decreased the molar proportion of acetate (by 9%; P≤0.003 and increased those of propionate and butyrate (P≤0.014. For CEL, the pre-digestion increased the gas and total VFA production (by 30 and 114%, shortened the lag time (by 32%, and only when it was combined with LSF inoculum 38 percentage units of acetate were replaced by butyrate (P≤0.039. Treatments had a minor influence on in vitro fermentation traits of SBP pectin. The results showed that the pre-digestion process influenced the in vitro caecal fermentation in rabbits, but the effects were influenced by donors’ diet and the incubated substrate. Pre-digestion of substrate is recommended before conducting in vitro caecal fermentations. The level of soluble fibre in the donors’ diet

To estimate the dietary share of ultra-processed foods and to determine its association with the overall nutritional quality of diets in Brazil. Cross-sectional. Brazil. A representative sample of 32 898 Brazilians aged ≥10 years was studied. Food intake data were collected. We calculated the average dietary content of individual nutrients and compared them across quintiles of energy share of ultra-processed foods. Then we identified nutrient-based dietary patterns, and evaluated the association between quintiles of dietary share of ultra-processed foods and the patterns' scores. The mean per capita daily dietary energy intake was 7933 kJ (1896 kcal), with 58·1 % from unprocessed or minimally processed foods, 10·9 % from processed culinary ingredients, 10·6 % from processed foods and 20·4 % from ultra-processed foods. Consumption of ultra-processed foods was directly associated with high consumption of free sugars and total, saturated and trans fats, and with low consumption of protein, dietary fibre, and most of the assessed vitamins and minerals. Four nutrient-based dietary patterns were identified. 'Healthy pattern 1' carried more protein and micronutrients, and less free sugars. 'Healthy pattern 2' carried more vitamins. 'Healthy pattern 3' carried more dietary fibre and minerals and less free sugars. 'Unhealthy pattern' carried more total, saturated and trans fats, and less dietary fibre. The dietary share of ultra-processed foods was inversely associated with 'healthy pattern 1' (-0·16; 95 % CI -0·17, -0·15) and 'healthy pattern 3' (-0·18; 95 % CI -0·19, -0·17), and directly associated with 'unhealthy pattern' (0·17; 95 % CI 0·15, 0·18). Dietary share of ultra-processed foods determines the overall nutritional quality of diets in Brazil.

To assess the compatibility between reduction of diet-related greenhouse gas emissions (GHGE) and nutritional adequacy, acceptability and affordability dimensions of diet sustainability. Dietary intake, nutritional composition, GHGE and prices were combined for 402 foods selected among those most consumed by participants of the Individual National Study on Food Consumption. Linear programming was used to model diets with stepwise GHGE reductions, minimized departure from observed diet and three scenarios of nutritional constraints: none (FREE), on macronutrients (MACRO) and for all nutrient recommendations (ADEQ). Nutritional quality was assessed using the mean adequacy ratio (MAR) and solid energy density (SED). France. Adults (n 1899). In FREE and MACRO scenarios, imposing up to 30 % GHGE reduction did not affect the MAR, SED and food group pattern of the observed diet, but required substitutions within food groups; higher GHGE reductions decreased diet cost, but also nutritional quality, even with constraints on macronutrients. Imposing all nutritional recommendations (ADEQ) increased the fruits and vegetables quantity, reduced SED and slightly increased diet cost without additional modifications induced by the GHGE constraint up to 30 % reduction; higher GHGE reductions decreased diet cost but required non-trivial dietary shifts from the observed diet. Not all the nutritional recommendations could be met for GHGE reductions ≥70 %. Moderate GHGE reductions (≤30 %) were compatible with nutritional adequacy and affordability without adding major food group shifts to those induced by nutritional recommendations. Higher GHGE reductions either impaired nutritional quality, even when macronutrient recommendations were imposed, or required non-trivial dietary shifts compromising acceptability to reach nutritional adequacy.

Adolescence represents an important period for the development of executive functions, which are a set of important cognitive processes including attentional control. However, very little is known regarding the associations of nutrition with components of executive functions in adolescence. Thus, the aim of this study was to investigate associations of dietary patterns and macronutrient composition with attention capacity in European adolescents. This cross-sectional study included 384 (165 boys and 219 girls) adolescents, aged 12·5-17·5 years, from five European countries in the Healthy Lifestyle in Europe by Nutrition in Adolescence study. Attention capacity was examined using the d2 Test of Attention. Dietary intake was assessed through two non-consecutive 24 h recalls using a computer-based self-administered tool. Three dietary patterns (diet quality index, ideal diet score and Mediterranean diet score) and macronutrient/fibre intakes were calculated. Linear regression analysis was conducted adjusting for age, sex, BMI, maternal education, family affluence scale, study centre and energy intake (only for Mediterranean diet score). In these adjusted regression analyses, higher diet quality index for adolescents and ideal diet score were associated with a higher attention capacity (standardised β=0·16, P=0·002 and β=0·15, P=0·005, respectively). Conversely, Mediterranean diet score or macronutrient/fibre intake were not associated with attention capacity (P>0·05). Our results suggest that healthier dietary patterns, as indicated by higher diet quality index and ideal diet score, were associated with attention capacity in adolescence. Intervention studies investigating a causal relationship between diet quality and attention are warranted.

Background: The nutritional and weight status of the mother influences not only her own health and foetal growth, but also the offspring’s future risk of diet-related chronic diseases. Given the rise in the proportion of pregnant women globally with overweight and diet-related chronic diseases, efforts to promote a healthy diet and weight management in pregnancy are urgently needed. Pregnant women may be motivated to eat healthily and be more receptive for nutrition-related information. Howev...

Position Statement: The International Society of Sports Nutrition (ISSN) bases the following position stand on a critical analysis of the literature regarding the effects of diet types (macronutrient composition; eating styles) and their influence on body composition. The ISSN has concluded the following. 1) There is a multitude of diet types and eating styles, whereby numerous subtypes fall under each major dietary archetype. 2) All body composition assessment methods have strengths and limitations. 3) Diets primarily focused on fat loss are driven by a sustained caloric deficit. The higher the baseline body fat level, the more aggressively the caloric deficit may be imposed. Slower rates of weight loss can better preserve lean mass (LM) in leaner subjects. 4) Diets focused primarily on accruing LM are driven by a sustained caloric surplus to facilitate anabolic processes and support increasing resistance-training demands. The composition and magnitude of the surplus, as well as training status of the subjects can influence the nature of the gains. 5) A wide range of dietary approaches (low-fat to low-carbohydrate/ketogenic, and all points between) can be similarly effective for improving body composition. 6) Increasing dietary protein to levels significantly beyond current recommendations for athletic populations may result in improved body composition. Higher protein intakes (2.3-3.1 g/kg FFM) may be required to maximize muscle retention in lean, resistance-trained subjects under hypocaloric conditions. Emerging research on very high protein intakes (>3 g/kg) has demonstrated that the known thermic, satiating, and LM-preserving effects of dietary protein might be amplified in resistance-training subjects. 7) The collective body of intermittent caloric restriction research demonstrates no significant advantage over daily caloric restriction for improving body composition. 8) The long-term success of a diet depends upon compliance and suppression or

To assess intergenerational associations between dental caries and nutritional status, oral hygiene habits, and diet. A cross-sectional study was conducted with three generations of 54 families. Inclusion criteria were senior citizens with an adult son/daughter who also had a child (five to 12 years old). Dental caries was assessed using the decayed, missing, filled, primary teeth (dmft) and permanent teeth (DMFT) indexes. Nutritional status was evaluated using the body mass index (BMI), waist circumference, and percentage of body fat. Dietary habits, oral hygiene habits, and socioeconomic status were evaluated using a structured questionnaire. Children/adolescents with higher BMI had a lower dmft/DMFT index, and those who never or almost never consumed fruits and vegetables as snacks had a higher dmft/ DMFT index. When parents did not visit the dentist regularly, children/adolescents had more teeth affected by dental caries. When parents consumed sugar two or more times between meals, the number of affected teeth in children/adolescents increased. When children/ adolescents had a higher body mass index and they consumed fruits/vegetables as snacks more frequently, their caries experiences were lower. When their parents' did not visit the dentist regularly and they consumed sugar between meals more frequently, the children's caries experiences were higher.

There is a great deal of spatial and temporal variation in the availability and nutritional quality of foods eaten by animals, particularly in temperate regions where winter brings lengthy periods of leaf and fruit scarcity. We analyzed the availability, dietary composition, and macronutrients of the foods eaten by the northern-most golden snub-nosed monkey (Rhinopithecus roxellana) population in the Qinling Mountains, China to understand food choice in a highly seasonal environment dominated by deciduous trees. During the warm months between April and November, leaves are consumed in proportion to their availability, while during the leaf-scarce months between December and March, bark and leaf/flower buds comprise most of their diet. When leaves dominated their diet, golden snub-nosed monkeys preferentially selected leaves with higher ratios of crude protein to acid detergent fiber. While when leaves were less available, bark and leaf/flower buds that were high in nonstructural carbohydrates and energy, and low in acid detergent fiber were selected. Southern populations of golden snub-nosed monkey can turn to eating lichen, however, the population studied here in this lichen-absent area have adapted to their cool deciduous habitat by instead consuming buds and bark. Carbohydrate and energy rich foods appear to be the critical resources required for the persistence of this species in temperate habitat. The dietary flexibility of these monkeys, both among seasons and populations, likely contributes to their wide distribution over a range of habitats and environments. © 2018 Wiley Periodicals, Inc.
Full Text Available Our objective was to determine gender differences in the impact of a nutritional intervention based on the self-determination theory and promoting the Mediterranean diet on changes in eating-related self-determined motivation and adherence to the Mediterranean diet. Changes in eating-related self-determined motivation were larger in men than in women in response to the intervention and at follow-up, but the magnitude of change decreased with time in both genders. Changes in eating-related self-determined motivation were positively associated with changes in the Mediterranean diet adherence in response to the intervention and at follow-up in men only, suggesting that the nutritional program seems to fit better men than women.

Diet and nutrition, particularly among low-income groups, is a key public health concern in the UK. Low levels of fruit and vegetable consumption, and obesity, especially among children, have potentially severe consequences for the future health of the nation. From a public health perspective, the UK government's role is to help poorer families make informed choices within healthy frameworks for living. However, the question is - to what extent are such policies in accordance with lay experiences of managing diet and nutrition on a low-income? This paper critically examines contemporary public health policies aimed at improving diet and nutrition, identifying the underlying theories about the influences on healthy eating in poor families, and exploring the extent to which these assumptions are based on experiential accounts. It draws on two qualitative systematic reviews - one prioritizing low-income mothers' accounts of 'managing' in poverty; and the other focusing on children's perspectives. The paper finds some common ground between policies and lay experiences, but also key divergencies. Arguably, the emphasis of public health policy on individual behaviour, coupled with an ethos of empowered consumerism, underplays material limitations on 'healthy eating' for low-income mothers and children. Health policies fail to take into account the full impact of structural influences on food choices, or recognize the social and emotional factors that influence diet and nutrition. In conclusion, it is argued that while health promotion campaigns to improve low-income families' diets do have advantages, these are insufficient to outweigh the negative effects of poverty on nutrition.

Context Dietary guidance for children emphasizes fruit over fruit juices but little is known about the potential nutritional and economic impact of substituting fruit for juice. Objective To estimate the nutritional and economic effects of substituting whole fruit for juice in the diets of children in the US. Design Secondary analyses using the 2001-2004 National Health and Nutrition Examination Survey (NHANES) and a national food price database. Energy, nutrient intakes and diet cost were estimated before and after fruit juices were completely replaced with fruit in three models that emphasized fruits that were fresh, low-cost, and widely-consumed and a fourth model that partially replaced juice with fruit, capping juice at recommended levels. Setting A nationwide, representative sample of children in the US. Participants 7,023 children ages 3-18. Main Outcome Measures Difference in energy, nutrient intakes and diet cost between observed and modeled diets. Results For children who consumed juice, replacement of all juice servings with fresh, whole fruit led to a projected reduction in dietary energy of 233 kJ/day (−2.6% [95% CI −5.1, −0.1%]), an increase in fiber of 4.3 grams/day (+31.1% [95% CI 26.4, 35.9%]) and an increase in diet cost of $0.54/day (+13.3% [95% CI 8.8, 17.8%]). Conclusions Substitution of juice with fresh fruit has the potential to reduce energy intake and improve the adequacy of fiber intake in children’s diets. This would likely increase costs for schools, childcare providers and families. Cost impacts could be minimized by selecting processed fruits but fewer nutritional gains would be achieved.

Full Text Available To explore the dietary changes needed to achieve nutritional adequacy across income levels at constant energy and diet cost.Individual diet modelling was used to design iso-caloric, nutritionally adequate optimised diets for each observed diet in a sample of adult normo-reporters aged ≥20 years (n = 1,719 from the Individual and National Dietary Survey (INCA2, 2006-2007. Diet cost was estimated from mean national food prices (2006-2007. A first set of free-cost models explored the impact of optimisation on the variation of diet cost. A second set of iso-cost models explored the dietary changes induced by the optimisation with cost set equal to the observed one. Analyses of dietary changes were conducted by income quintiles, adjusting for energy intake, sociodemographic and socioeconomic variables, and smoking status.The cost of observed diets increased with increasing income quintiles. In free-cost models, the optimisation increased diet cost on average (+0.22 ± 1.03 euros/d and within each income quintile, with no significant difference between quintiles, but with systematic increases for observed costs lower than 3.85 euros/d. In iso-cost models, it was possible to design nutritionally adequate diets whatever the initial observed cost. On average, the optimisation at iso-cost increased fruits and vegetables (+171 g/day, starchy foods (+121 g/d, water and beverages (+91 g/d, and dairy products (+20 g/d, and decreased the other food groups (e.g. mixed dishes and salted snacks, leading to increased total diet weight (+300 g/d. Those changes were mostly similar across income quintiles, but lower-income individuals needed to introduce significantly more fruit and vegetables than higher-income ones.In France, the dietary changes needed to reach nutritional adequacy without increasing cost are similar regardless of income, but may be more difficult to implement when the budget for food is lower than 3.85 euros/d.

Develop the Index of Nutritional Purchasing Power Parity (Nut3-CiO) as an instrument to compare the caloric costs of a healthy versus an unhealthy diet between regions or cities in a country over time. Indices of caloric prices were constructed and the "law of one price" was used to derive the Nut3-CiO index. Caloric inflation rates were obtained using basic descriptive statistics. The Nut3-CiO was applied in the major cities of Mexico during the period from January 1996 to December 2010. The statistical behavior of the Nut3-CiO revealed that, in Mexican cities, products for a typical diet are less expensive than products for a healthy diet. The findings showed a cyclical behavior to the index, a high correlation between inflation for the typical diet and inflation for the market basket, and a high persistence of prices. The Nut3-CiO index makes it possible to periodically compare the price differential of two types of diets-typical and healthy-between cities in a single country. This instrument could help health authorities identify the cities where it is easier or more difficult for consumers to access a typical or healthy diet in terms of cost. Furthermore, it makes it possible to estimate the percentage adjustment necessary in each city to attain levels of nutritional purchasing power parity.
Full Text Available Background: The importance of adequate nutritional support in burned patients cannot be overemphasised. For adequate long-term compliance by the patients, diet should be formulated in accordance with their pre-burn dietary habits, religious beliefs, and tastes. Patients and Methods: A study was conducted in 42 consecutive patients suffering from 10% to 50% of 2 nd and 3 rd degree thermal burns with the aim to compare nutritional status, clinical outcome, and cost-effectiveness of vegetarian and non-vegetarian diets. The patients were divided into two groups depending upon their pre-injury food habits. Total calories were calculated by Curreri formula. Both groups were compared by various biochemical parameters, microbiological investigations, weight , status of wound healing, graft take, and hospital stay and they were followed for at least 60 days postburn. Results: The results were comparable in both groups. Vegetarian diet was found to be more palatable and cost-effective. Conclusion: Vegetarian diet is a safe and viable option for the patients suffering from burn injury. The common belief that non-vegetarian diet is superior to vegetarian diet is a myth.

Full Text Available Poor diet quality is implicated in almost every disease and health issue. And yet, in most advanced market economies diet quality is poor, with a minority meeting guidelines for healthy eating. Poor diet is thus responsible for substantial disease burden.Societies have at their disposal a range of strategies to influence diet behaviors. These can be classified into; i population level socio-educational approaches to enhance diet knowledge; ii pricing incentives (subsidies on healthy foods, punitive taxes on unhealthy foods; iii regulations to modify the food environment, and iv the provision of clinical dietetic services. There is little evidence that societies are active in implementing the available strategies. Advertising of ‘junk foods’ is largely unchecked, contrasting with strict controls on advertising tobacco products, which also attract punitive taxes. Access to dieticians is restricted in most countries, even in the context of universal health care. In Australia in 2011 there were just 2,969 practicing dieticians/nutritionists or 1.3 clinicians per 10,000 persons, compared with 5.8 physiotherapists per 10,000 persons, 14.8 general practitioners (family physicians per 10,000 persons or 75 nurses per 10,000 persons.Given the major role of diet in health it is time to implement comprehensive national nutrition strategies capable of effecting change. Such strategies need to be multi-component, incorporating both public health approaches and expanded publicly funded dietetic services. Access to individualized dietetic services is needed by those at risk, or with current chronic conditions, given the complexity of the diet message, the need for professional support for behavior change and to reflect individual circumstances. The adoption of a comprehensive nutrition strategy offers the promise of substantial improvement in diet quality, better health and wellbeing and lower health care costs.
Importance of taste, nutrition, cost and convenience in relation to diet quality: Evidence of nutrition resilience among US adults using National Health and Nutrition Examination Survey (NHANES) 2007-2010.

Concerns with taste, nutrition, cost, and convenience are said to be key influences on food choices. This study examined the importance of food-related attitudes in relation to diet quality using US national level data. Interactions by socioeconomic status (SES), gender and race/ethnicity were tested. Analyses of 8957 adults from National Health and Nutrition Examination Survey (NHANES 2007-2010) were conducted in 2014-15. Perceived importance of taste, nutrition, cost, and convenience in dietary choices were assessed using 4-point Likert scales. Education and family income-to-poverty ratio (FIPR) were SES indicators. Healthy Eating Index (HEI-2010), a measure of adherence to 2010 dietary guidelines, was the diet quality measure. Survey-weighted regressions examined associations between attitudes and HEI, and tested for interactions. Taste was rated as "very important" by 77.0% of the US adults, followed by nutrition (59.9%), cost (39.9%), and convenience (29.8%). However, it was the perceived importance of nutrition that most strongly predicted HEI (β: +8.0 HEI scores among "very important" vs. "not at all important"). By contrast, greater importance for taste and convenience had a weak inverse relation with HEI (β: -5.1 and -1.5 respectively), adjusting for SES. Significant interactions were observed by race/ethnicity, but not SES and gender. Those who prioritized nutrition during food shopping had higher-quality diets regardless of gender, education and income in the US. Certain racial/ethnic groups managed to eat healthy despite attaching importance to cost and convenience. This is the first evidence of nutrition resilience among US adults using national data, which has huge implications for nutrition interventions. Published by Elsevier Inc.

Brief nutrition screening tools are desired for research and practice. Seniors in the Community: Risk Evaluation for Eating and Nutrition (SCREEN-II, 14 items) and the abbreviated version SCREEN-II-AB (8 items) are valid and reliable nutrition screening tools for older adults. This exploratory study used a retrospective cross-sectional design to determine the construct validity of a subset of 3 items (weight loss, appetite, and swallowing difficulty) currently on the SCREEN-II and SCREEN-II-AB tools. Secondary data on community-dwelling senior males (n = 522, mean ± SD age = 86.7 ± 3.0 years) in the Manitoba Follow-up Study (MFUS) study were available for analysis. Participants completed the mailed MFUS Nutrition Survey that included SCREEN-II items and questions pertaining to self-rated health, diet healthiness, and rating of the importance of nutrition towards successful aging as the constructs for comparison. Self-perceived health status (F = 14.7, P importance to aging (ρ = 0.10, P = 0.03) were correlated with the 3-item score. Inferences were consistent with associations between these construct variables and the full SCREEN-II. Three items from SCREEN-II and SCREEN-II-AB demonstrate initial construct validity with self-perceived health status and diet healthiness ratings by older males; further exploration for criterion and predictive validity in more diverse samples is needed.

Full Text Available Introductions: Irritable bowel syndrome (IBS is one of the most prevalent functional gastrointestinal disorders in the population. It is a complex and multifactorial disease in which biological, psychological and social factors act at multiple levels on the disease. Diagnosed according to ROMA IV and characterized mainly by abdominal pain and change in bowel habits, it does not have a standard treatment, so it focuses on minimizing gastrointestinal symptoms. The FODMAP diet has been appeared as an effective treatment of IBS. Objectives: The main objective of this study was to test the efficacy of the FODMAP diet in its different phases of nutrition therapy in order to reduce gastrointestinal symptoms and to increase quality of life. Methods: A prospective experimental study with duration of twelve weeks was designed under one case, a 35-year-old woman suffering from IBS for 7 years. The dietary treatment was divided into three phases, which was being realised with 12 different diets, dietary education and dietary advice, assessment symptoms, quality of life, type of stool, diet adherence and satisfaction about the nutrition therapy. Results: The gastrointestinal symptoms and quality of life improved in comparison to the start of the study, as well did the stool in outbreak crisis and routinely situations. By contrast, no relation between the reintroduced foods that produced symptoms with FODMAP’s content was found. Conclusions: The nutritional treatment of FODMAP diet is an effective treatment for IBS because it reduces the gastrointestinal symptoms, increases the quality of life and the control of the patient towards the diet.

To estimate the nutritional and economic effects of substituting whole fruit for juice in the diets of children in the United States. Secondary analyses using the 2001-2004 National Health and Nutrition Examination Survey and a national food prices database. Energy intakes, nutrient intakes, and diet costs were estimated before and after fruit juices were completely replaced with fruit in 3 models that emphasized fruits that were fresh, inexpensive, and widely consumed and in a fourth model that partially replaced juice with fruit, capping juice at recommended levels. A nationwide, representative sample of children in the United States. A total of 7023 children aged 3 to 18 years. Systematic complete or partial replacement of juice with fruit. Difference in energy intakes, nutrient intakes, and diet costs between observed and modeled diets. For children who consumed juice, replacement of all juice servings with fresh, whole fruit led to a projected reduction in dietary energy of 233 kJ/d (-2.6% difference [95% CI, -5.1% to -0.1%]), an increase in fiber of 4.3 g/d (31.1% difference [95% CI, 26.4%-35.9%]), and an increase in diet cost of $0.54/d (13.3% difference [95% CI, 8.8%-17.8%]). Substitution of juice with fresh fruit has the potential to reduce energy intake and improve the adequacy of fiber intake in children's diets. This would likely increase costs for schools, childcare providers, and families. These cost effects could be minimized by selecting processed fruits, but fewer nutritional gains would be achieved.
Full Text Available Our case involved a 58-year-old man with a medical history of moderately differentiated esophageal squamous cell carcinoma. Positron emission tomography (PET and computed tomography (CT scan revealed a tumor in the upper two-thirds of the esophagus, with a maximal length of 14.4 cm and at least 6 enlarged lymph nodes. Concurrent chemoradiotherapy (CCRT was performed on June 12, 2015, and a chest CT 2 weeks later revealed partial tumor response and shrinkage of the right upper paratracheal lymph node. The patient (cT3N3MO, stage III c underwent esophagectomy with gastric tube reconstruction, lymph node dissection, and jejunostomy on July 6, 2015. Bodyweight (BW loss occurred because of inadequate calorie intake. The nutrition support team (NST commenced an intervention and estimated the patient's malnutrition status from the BW loss (>8% in 3 months, body mass index (BMI, 21 kg/m2, triceps skinfold thickness (TSF, 5.7 mm, arm circumference (AC, 20 cm, and serum albumin level (2.7 g/dL. The NST administered an enteral nutrition formula with an elemental diet (Peptamen through enterostomy feeding, and provided meals according to the patient's digestive ability. The Scored Patient-Generated Subjective Global Assessment (PG-SGA improved from 13 to 5, and energy support increased from 10 to 30 kcal/kg BW, with the BMI rising from 21 to 22 kg/m2, TSF from 5.7 to 7.0 mm, AC from 20 to 21.7 cm, and serum albumin level from 2.7 to 3.1 g/dL. The patient's wound healed completely.

The study also sought to assess the potential influence of practitioner age, gender, practice location (major city versus regional, therapeutic-endorsement status and personal nutritional supplementation habits upon management practices in these areas.A survey was electronically distributed to Australian optometrists (n = 4,242. Respondents anonymously provided information about their personal demographics and lifestyle behaviors (i.e., age, gender, practice location, therapeutic-endorsement status, smoking status, nutritional supplement intake and routine patient management practices with respect to advice across three domains: smoking, diet and nutritional supplementation. Multivariate logistic regression analyses were performed to assess for potential effects of the listed factors on practitioner behavior.A total of 283 completed surveys were received (completed survey response rate: 6.7%. Fewer than half of respondents indicated routinely asking their patients about smoking status. Younger practitioners were significantly (p < 0.05 less likely to enquire about patients' smoking behaviors, but this did not extend to counseling for smoking cessation. Almost two-thirds of respondents indicated routinely counseling patients about diet. About half of practitioners specified routinely asking their patients about nutritional supplement intake; this form of questioning was significantly more likely if the respondent was female (p < 0.05. Practitioners who recommended nutritional supplements most commonly did so for age-related macular degeneration (91.2% and dry eye disease (63.9%. The primary source of evidence used to guide practitioners' nutrition-related patient management was reported to be peer-reviewed publications.These findings

Half of examined patients appraised nutrition variety as good but at the same time claimed the there was not enough fruits and vegetables.
Full Text Available Diet-related adaptive gene (DRAG polymorphisms identified in specific populations are associated with chronic disorders in carriers of the adaptive alleles due to changes in dietary and lifestyle patterns in recent times. Mexico’s population is comprised of Amerindians (AM and Mestizos who have variable AM, European (EUR and African genetic ancestry and an increased risk of nutrition-related chronic diseases. Nutritional advice based on the Mexican genome and the traditional food culture is needed to develop preventive and therapeutic strategies. Therefore, we aimed to provide a prevalence profile of several DRAG polymorphisms in the Mexican population, including Central West (CW Mexico subpopulations. Geographic heat maps were built using ArcGIS10 (Esri, Redlands, CA, USA software, based on the published data of the MTHFR C677T (rs1801133, ABCA1 Arg230Cys (rs9282541, APOE T388C (rs429358/C526T (rs7412, LCT C-13910T (rs4988235 polymorphisms and AMY1 copy number variation (CNV. Also, new data obtained by allelic discrimination-real-time polymerase chain reaction (RT-PCR assays for the MTHFR, ABCA1, and APOE polymorphisms as well as the AMY1 CNV in the CW Mexico subpopulations with different proportions of AM and EUR ancestry were included. In the CW region, the highest frequency of the MTHFR 677T, ABCA1 230C and APOE ε4 adaptive alleles was observed in the AM groups, followed by Mestizos with intermediate AM ancestry. The LCT-13910T allele frequency was highest in Mestizos-EUR but extremely low in AM, while the AMY1 diploid copy number was 6.82 ± 3.3 copies. Overall, the heat maps showed a heterogeneous distribution of the DRAG polymorphisms, in which the AM groups revealed the highest frequencies of the adaptive alleles followed by Mestizos. Given these genetic differences, genome-based nutritional advice should be tailored in a regionalized and individualized manner according to the available foods and Mexican traditional food culture that

Full Text Available A portable Near Infrared Reflectance Spectroscopy (NIRS instrument was applied to 40 growing rabbits to determine body and tissue differences induced by experimental factors. The rabbits were examined at 2 live sites, in 7 warm carcass tissues and in longissimus dorsi muscle samples prepared in ethanol. For this purpose, the method was applied in a bi-factorial experiment concerning the dietary oil source (O (maize vs. palm oil and Curcuma longa (C supplementation (0 and 3 g/kg, respectively. Significant chemical differences emerged for palmitic, oleic and linoleic acids in the longissimus dorsi muscle due to the O factor and for linolenic acid due to the C factor. The NIRS spectra and chemical analyses were elaborated by the Partial Least Squares (PLS method, and the rsquares in cross-validation (R2cv were retained as measure of the unoriented differentiation between the levels of the planned factor for each landmark and fatty acid (FA profile. Multivariate PLS analysis of the FA muscular fat showed that the O factor induced strong differentiation (R2cv: 0.96, while less influence (0.33 was observed for the C factor. The model based on the NIRS radiation of the landmarks clearly shows the O factor effects, not only in the perirenal (0.90 and scapular (0.85 fats, but also in the belly (0.76, liver (0.73 and hind legs (0.72. Whereas the C effects were only expressed in the live animals (ears: 0.66 and abdominal wall: 0.58 and in post-mortem (liver: 0.60. It was concluded that a preliminary NIRS scan of the carcass and of live rabbits can point out the presence of intrinsic experimental effects concerning the lipid metabolism of polyunsaturated FA of the n-6 series (O factor and n-3 series (C factor.

Poor diet quality is implicated in almost every disease and health issue. And yet, in most advanced market economies diet quality is poor, with a minority meeting guidelines for healthy eating. Poor diet is thus responsible for substantial disease burden. Societies have at their disposal a range of strategies to influence diet behaviors. These can be classified into: (i) population level socio-educational approaches to enhance diet knowledge; (ii) pricing incentives (subsidies on healthy foods, punitive taxes on unhealthy foods); (iii) regulations to modify the food environment, and (iv) the provision of clinical dietetic services. There is little evidence that societies are active in implementing the available strategies. Advertising of "junk foods" is largely unchecked, contrasting with strict controls on advertising tobacco products, which also attract punitive taxes. Access to dieticians is restricted in most countries, even in the context of universal health care. In Australia in 2011 there were just 2,969 practicing dieticians/nutritionists or 1.3 clinicians per 10,000 persons, compared with 5.8 physiotherapists per 10,000 persons, 14.8 general practitioners (family physicians) per 10,000 persons or 75 nurses per 10,000 persons.

bacterial groups (Clostridium, Enterococcus, Streptococcus species) increased with time. We conclude that a switch from parenteral to enteral nutrition rapidly induces diet-dependent histopathological, functional, and proinflammatory insults to the immature intestine. Great care is required when introducing......-six preterm pigs were fed total parenteral nutrition (TPN) for 48 h followed by enteral feeding for 0, 8, 17, or 34 h with either colostrum (Colos, n = 20) or formula (Form, n = 31). Macroscopic NEC lesions were detected in Form pigs throughout the enteral feeding period (20/31, 65%), whereas most Colos pigs...... no histopathological lesions, increased maltase activity, and induced changes in gene expressions related to tissue development.

Systemic lupus erythematosus (SLE) is a chronic inflammatory and autoimmune disease characterised by multiple organ involvement and a large number of complications. SLE management remains complicated owing to the biological heterogeneity between patients and the lack of safe and specific targeted therapies. There is evidence that dietary factors can contribute to the geoepidemiology of autoimmune diseases such as SLE. Thus, diet therapy could be a promising approach in SLE owing to both its potential prophylactic effects, without the side effects of classical pharmacology, and its contribution to reducing co-morbidities and improving quality of life in patients with SLE. However, the question arises as to whether nutrients could ameliorate or exacerbate SLE and how they could modulate inflammation and immune function at a molecular level. The present review summarises preclinical and clinical experiences to provide the reader with an update of the positive and negative aspects of macro- and micronutrients and other nutritional factors, including dietary phenols, on SLE, focusing on the mechanisms of action involved.

The objective of this study was to determine whether dietary boron (B) affects the strength, density and mineral composition of teeth and mineral density of alveolar bone in rabbits with apparent obesity induced by a high-energy diet. Sixty female, 8-month-old, New Zealand rabbits were randomly assigned for 7 months into five groups as follows: (1) control 1, fed alfalfa hay only (5.91 MJ/kg and 57.5 mg B/kg); (2) control 2, high energy diet (11.76 MJ and 3.88 mg B/kg); (3) B10, high energy diet + 10 mg B gavage/kg body weight/96 h; (4) B30, high energy diet + 30 mg B gavage/kg body weight/96 h; (5) B50, high energy diet + 50 mg B gavage/kg body weight/96 h. Maxillary incisor teeth of the rabbits were evaluated for compression strength, mineral composition, and micro-hardness. Enamel, dentin, cementum and pulp tissue were examined histologically. Mineral densities of the incisor teeth and surrounding alveolar bone were determined by using micro-CT. When compared to controls, the different boron treatments did not significantly affect compression strength, and micro-hardness of the teeth, although the B content of teeth increased in a dose-dependent manner. Compared to control 1, B50 teeth had decreased phosphorus (P) concentrations. Histological examination revealed that teeth structure (shape and thickness of the enamel, dentin, cementum and pulp) was similar in the B-treated and control rabbits. Micro CT evaluation revealed greater alveolar bone mineral density in B10 and B30 groups than in controls. Alveolar bone density of the B50 group was not different than the controls. Although the B treatments did not affect teeth structure, strength, mineral density and micro-hardness, increasing B intake altered the mineral composition of teeth, and, in moderate amounts, had beneficial effects on surrounding alveolar bone.

Background: A rapid advance in enteral feeding is associated with necrotizing enterocolitis (NEC) in preterm infants. Therefore, minimal enteral nutrition (MEN) combined with parenteral nutrition (PN) is common clinical practice, but the effects on NEC and intestinal function remain poorly...... characterized. It was hypothesized that a commonly used MEN feeding volume (16-24 mL/kg/d) prevents NEC and improves intestinal structure, function, and microbiology in preterm pigs. Methods: After preterm birth pigs were stratified into 4 nutrition intervention groups that received the following treatments: (1...... later formula-induced gut dysfunction and NEC. However, in CF pigs, intestinal lesions were restricted to the colon, compared with all regions in OF and FF pigs, which indicated proximal protection of colostrum MEN.

To suggest methods for maintaining an adequate nutritional status for elderly patients with dementia by evaluating the relationships between oral status, physical and mental health, and feeding conditions. Feeding difficulties in dementia patients are related to food intake, and failure to eat may be associated with weight loss in long-term care facilities. The relationship between compromised oral function and diet is still unclear. A cross-sectional study of 94 elderly women with dementia (mean age 89.6 +/- 5.6 years) from a nursing home was undertaken to investigate their oral, physical and mental and nutritional status. There were significant differences in serum albumin (p = 0.0284), N-ADL (p = 0.0005), NM scale (p = 0.0004) and HDS-R (p = 0.0004) between denture wearers and non-denture wearers. However, there were no significant differences in body mass index between denture wearers and non-denture wearers. A suitable type of diet and assistance with feeding could maintain the nutritional status of elderly patients with dementia if they are still feeding themselves. The nutritional support team will benefit from the participation of a dentist.

Curcuma comosa has been known to have potential use in cardiovascular diseases, but its immunoregulatory role in atherosclerosis development and liver toxicity has not been well studied. We therefore investigated the effects of Curcuma comosa on the expression of atherosclerosis-related cytokine genes in rabbits fed a high-cholesterol diet. Twelve male New Zealand White rabbits were treated with 1.0% cholesterol for one month and were subsequently treated with 0.5% cholesterol either alone, or in combination with 5mg/kg/day of simvastatin or with 400mg/kg/day of Curcuma comosa powder for three months. The expression of IL-1, MCP-1, TNF-α, IL-10, and TGF-β in the isolated abdominal aorta and liver were determined by real-time RT-PCR. Liver toxicity was determined by hepatic enzyme activity. Curcuma comosa significantly decreased the expression of pro-inflammatory cytokines, leading to a stronger reduction in IL-1, MCP-1, and TNF-α expression compared to that was suppressed by simvastatin treatment. However, neither Curcuma comosa nor simvastatin affected the expression of anti-inflammation cytokines. In the liver, Curcuma comosa insignificantly decreased the expression of pro-inflammatory cytokines and significantly increased the expression of the anti-inflammatory cytokine IL-10 without altering the activity of hepatic enzymes. In contrast, simvastatin significantly increased the MCP-1 and TNF-α expressions and serum ALT level, without affecting the expression of anti-inflammatory cytokines. In this study, we demonstrated that Curcuma comosa exerts anti-inflammatory activity in the aorta and liver without causing liver toxicity, indicating that Curcuma comosa is a potential candidate as an alternative agent in cardiovascular disease therapy.

To compare the effects of a low-starch, high-fibre diet [LSHF; 51.6% neutral detergent fibre (NDF), 3.0% starch, 14.8% crude protein (CP)] and a high-starch, low-fibre diet (HSLF; 33.3% NDF, 20.0% starch, 19.6% CP) on the nutritional status of captive exotic ruminants, 16 mule deer (Odocoileus hemionus) were fed one of these two diets ad libitum with ≤25% alfalfa hay cubes from 10 days to 68 weeks of age. During five sampling periods beginning in November and spaced 6-12 weeks apart thereafter, feed intake, rumen and blood chemistry, faecal scores, growth and body condition were measured. Dry matter intake, digestible energy intake, time spent ruminating and feeding and blood acetate concentration were greater for deer fed LSHF (p 0.05). These findings show pelleted diets with less starch, more fibre, and reduced protein met the energy and protein requirements of growing mule deer, a medium-sized browsing ruminant, as well as traditional grain-based diets while more closely mimicking natural forages and stimulating a more natural feeding behaviour. © 2010 Blackwell Verlag GmbH.

The study aims were to (i) identify determinants of Nutrition Facts Panel (NFP) use and (ii) describe the association between NFP use and dietary intake among Latinos with type 2 diabetes. Baseline cross-sectional data from a clinical trial were used to assess the association between NFP use and dietary intake. Diet was measured using two methods: (i) a diet quality score (the Healthy Eating Index-2010) derived from a single 24 h recall and (ii) dietary pattern (exploratory factor analyses) from an FFQ. Multivariable logistic and non-parametric quantile regressions were conducted, as appropriate. Settings Hartford County, Connecticut, USA. Latino adults (n 203), ≥21 years of age, with diagnosed type 2 diabetes, glycosylated Hb≥7 %, and without medical conditions limiting physical activity. Participants' education level, diabetes-related knowledge and English speaking were positively associated with NFP use. At the higher percentiles of diet quality score, NFP use was significantly associated with higher diet quality. Similarly, NFP users were more likely to consume a 'healthy' dietary pattern (P=0·003) and less likely to consume a 'fried snack' pattern (P=0·048) compared with NFP non-users. The association between reported NFP use and diet quality was positive and significantly stronger among participants who reported consuming a healthier diet. While NFP use was associated with a healthier dietary pattern, not using NFP was associated with a less-healthy, fried snack pattern. Longitudinal studies are needed to understand whether improving NFP use could be an effective intervention to improve diet quality among Latinos with type 2 diabetes.

Full Text Available Objective: To assess the nutritional value of weight-loss diets disclosed in non-scientific magazines. Methods: A quantitative cross-sectional study carried out in two phases (first investigation in 2007; second investigation in 2009, in which 120 weight-loss diets were randomly selected from 24 magazines divided into three groups based on cost. The menus were evaluated with regard to calories, macronutrients and fiber, using the Diet Pro 2 program. The SPSS program (version 15.0 was used for statistical analysis, with the results expressed as mean, standard deviation and confidence intervals. Two-way analysis of variance (ANOVA with Tukey’s paired post hoc comparison was used for the quantitative study of the nutrients in each group of magazines and each phase of the study. The Student’s t-test was used for the comparisons of mean values obtained with the diets and established recommendations. The level of significance was set at 5.0%. Results: The energy supply was higher in 2007. Over time, mean protein content in the diets diminished, lipid content remained similar and glucose content increased. Based on the recommended values, the diets were characterized as hypoglycemic, high-protein and normolipidemic. The content of micronutrients was lower than recommended amounts in both years assessed. The fiber content increased in the second year in relation to the first, but did not reach the recommended level. Conclusion: Diets showed inadequacies of macro and micronutrients in the two studied years, with an imbalance between their components.

Microalgae, as primary producers of EPA and DHA, are among the most prominent alternative sources to fish oil for n-3 long-chain PUFA in animal and human nutrition. The present study aimed to assess technical, nutritional and fish health aspects of producing n-3-rich Atlantic salmon (Salmo salar) fish fillets by dietary supplementation of increasing levels of a DHA-producing Schizochytrium sp. and reduced or without use of supplemental fish oil. Atlantic salmon smolt were fed diets with graded levels of microalgae for 12 weeks, during which all fish showed high feed intake rates with postprandial plasma leptin levels inversely correlating with final mean fish body weights. Fish performance was optimal in all experimental treatments (thermal growth coefficient about 4·0 and feed conversion ratio 0·8-0·9), protein digestibility was equal in all diets, whereas dietary lipid digestibility inversely correlated with the dietary levels of the SFA 16 : 0. Fillet quality was good and similar to the control in all treatments in terms of n-3 long-chain PUFA content, gaping, texture and liquid losses during thawing. Histological fluorescence staining and immunofluorescence analysis of salmon intestines (midgut: base of intestine and villi) revealed significant effects on slime, goblet cell production and inducible nitric oxide synthase (iNOS) activity with increasing levels of dietary Schizochytrium sp. supplementation. Microarray analysis did not reveal any signs of toxicity, stress, inflammation or any other negative effects from Schizochytrium sp. supplementation in diets for Atlantic salmon.

Bone mass is influenced by genetic and environmental factors. Recent studies have highlighted associations between maternal nutritional status during pregnancy and bone mass in the offspring. We hypothesized that maternal calcium intakes and circulating micronutrients during pregnancy are related to bone mass in Indian children. DESIGN/SETTING/PARTICIPANTS/MAIN OUTCOME MEASURES: Nutritional status was measured at 18 and 28 wk gestation in 797 pregnant rural Indian women. Measurements included anthropometry, dietary intakes (24-h recall and food frequency questionnaire), physical workload (questionnaire), and circulating micronutrients (red cell folate and plasma ferritin, vitamin B12, and vitamin C). Six years postnatally, total body and total spine bone mineral content and bone mineral density (BMD) were measured using dual-energy x-ray absorptiometry (DXA) in the children (n = 698 of 762 live births) and both parents. Both parents' DXA measurements were positively correlated with the equivalent measurements in the children (P pregnancy (milk, milk products, pulses, non-vegetarian foods, green leafy vegetables, fruit) had higher total and spine bone mineral content and BMD, and children of mothers with higher folate status at 28 wk gestation had higher total and spine BMD, independent of parental size and DXA measurements. Modifiable maternal nutritional factors may influence bone health in the offspring. Fathers play a role in determining their child's bone mass, possibly through genetic mechanisms or through shared environment.

Gamma radiation is used to sterilize diets for specific pathogen-free (SPF) animals. Because a gamma-irradiated diet was linked to leukoencephalomyelopathy in SPF cats, we investigated the effects of ‘typical’ (28.9–34.3 kGy) and ‘high-end’ (38.4–48.7 kGy) doses of gamma irradiation and of pasteurization (at 107 °C for 15 min) on the amounts of fat; protein; carbohydrate (and taurine in cat diet); vitamins A, E, B1, B2, B6, and B12; and peroxide in commercially available dry cat, dog, and rodent diets. The only treatment-related changes occurred with vitamin A and peroxide. The typical and high-end doses of gamma irradiation reduced the vitamin A level of the cat diet to 42% and 30% of the untreated value, respectively—levels below recommended allowances for growth and reproduction. Only the higher irradiation dose reduced vitamin A in the rodent diet, and neither dose altered the canine diet. Pasteurization reduced the vitamin A content of the cat diet to 50% of its original level, which was within the recommended level for this species. Irradiation increased the peroxide content of all 3 animal diets: by approximately 11-fold with the typical dose and by 14- to 25-fold with the high-end dose. Therefore gamma irradiation can have profound, selective effects on the vitamin A and peroxide contents of dry diets, and caution is advised when feeding such diets long-term and exclusively to SPF animals, particularly cats. Furthermore, pasteurization (with its fewer deleterious effects) may represent an alternative method of decontaminating diets for rodents, dogs, and cats. PMID:19049256
Full Text Available Diet and nutrition have been reported to be associated with many common chronic diseases and blood-based assessment would be vital to investigate the association and mechanism, however, blood-based prospective studies are limited. The Harbin Cohort Study on Diet, Nutrition and Chronic Non-communicable Diseases was set up in 2010. From 2010 to 2012, 9,734 participants completed the baseline survey, including demographic characteristics, dietary intake, lifestyles and physical condition, and anthropometrics. A re-survey on 490 randomly selected participants was done by using the same methods which were employed in the baseline survey. For all participants, the mean age was 50 years and 36% of them were men. Approximately 99.4 % of cohort members donated blood samples. The mean total energy intake was 2671.7 kcal/day in men and 2245.9 kcal/day in women, the mean body mass index was 25.7 kg/m2 in men and 24.6 kg/m2 in women, with 18.4% being obese (≥ 28 kg/m2, 12.7% being diabetic, and 29.5% being hypertensive. A good agreement was obtained for the physical measurements between the baseline survey and re-survey. The resources from the cohort and its fasting and postprandial blood samples collected both at baseline and in each follow-up will be valuable and powerful in investigating relationship between diet, nutrition and chronic diseases and discovering novel blood biomarkers and the metabolism of these biomarkers related to chronic diseases.

The Mini Nutritional Assessment (MNA) is a well-validated instrument examining the nutritional status of older people. The aim of this study was to examine how older people's energy and nutrient intakes are associated with the MNA and to determine how sensitive and specific MNA is in identifying those having low energy and protein intakes. This cross-sectional study combined data from five nutritional studies (N=900): both home-dwelling and institutionalized older people without and with disabilities. Their nutritional status was assessed with MNA, and nutrient intakes were retrieved from 1 to 3day food diaries. Nutrient intakes were divided according to MNA status (normal nutritional status, at-risk of malnutrition, malnourished). Sensitivity, specificity, and likelihood ratios of MNA of various cut-off points were tested with recommended protein and energy intakes. ROC curves was constructed. Energy, protein and most nutrient intakes showed logical linear trends according to MNA classes. However, more than three-fourths of the participants with MNA>23.5 had lower than recommended protein intakes. Sensitivity of MNA ranged from 0.32 to 0.82 for recommended energy (F:1570kcal/d/M:2070kcal/d) and protein intakes (1.0g/kg BW or 1.2g/kgBW) cut-off points, and specificity from 0.75 to 0.25, respectively. AUC values were low (0.52-0.53). MNA status was consistently associated with nutrient intakes and diet quality. However, a high proportion of older people even with normal nutritional status had poor energy and protein intakes. Thus, MNA does not identify all those with poor nutrient intakes who may be at risk of developing malnutrition. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Full Text Available Based on data from the 2010–2011 Korean National Health and Nutrition Examination Survey, we investigated correlations between micronutrients in the diet of family members and the possible risk factors for children and adolescents consuming an inadequate diet. We examined two-generation households with children aged 2–18 years. The quality of the family diet with regard to the following nine nutrients (protein, calcium, phosphorous, iron, vitamin A, vitamin B1, vitamin B2, niacin, and vitamin C was assessed based on the Index of Nutritional Quality. Correlations between quality of diet and selected variables were analyzed using the Statistical Analysis for Genetic Epidemiology software, and those between diet quality and potential risk factors for poor diet in offspring were analyzed using multinomial logistic regression. Overall, calcium was the most commonly under-consumed micronutrient. More than half of sons and daughters showed insufficient vitamin A, vitamin C, and iron intake, and both mothers and fathers showed insufficiency with respect to vitamin A, vitamin B2, and vitamin C. The correlation between a poor diet in parents and that in offspring was 0.17 (p < 0.0001, and this correlation coefficient was higher between mothers and offspring than between fathers and offspring. Additionally, eating breakfast provided a significant protective effect against the risk of poor nutrition in offspring, even after adjusting for covariates. Our results add to evidence indicating that children should be encouraged to eat breakfast to improve the quality of their diet.

This study assessed the effects of different nutrition levels of diets on growth performance and carcass characteristics of Hainan black goat. Twenty-four goats were divided into six diet treatments, which consisted of two levels of crude protein (CP; 15 and 17 %) and three levels of digestive energy (DE; 11.72, 12.55, and 13.39 MJ/kg). The results revealed that 17 % CP significantly (P 0.05) on carcass characteristics of the goats. The mRNA expression levels of insulin-like growth factor 1 in muscle tissues increased with increasing CP and DE levels (P < 0.05).
Full Text Available Mediterranean Diet (MedDiet adherence has been proven to produce numerous health benefits. In addition, nutrigenetic studies have explained some individual variations in the response to specific dietary patterns. The present research aimed to explore associations and potential interactions between MedDiet adherence and genetic background throughout the Food4Me web-based nutritional intervention. Dietary, anthropometrical and biochemical data from volunteers of the Food4Me study were collected at baseline and after 6 months. Several genetic variants related to metabolic risk features were also analysed. A Genetic Risk Score (GRS was derived from risk alleles and a Mediterranean Diet Score (MDS, based on validated food intake data, was estimated. At baseline, there were no interactions between GRS and MDS categories for metabolic traits. Linear mixed model repeated measures analyses showed a significantly greater decrease in total cholesterol in participants with a low GRS after a 6-month period, compared to those with a high GRS. Meanwhile, a high baseline MDS was associated with greater decreases in Body Mass Index (BMI, waist circumference and glucose. There also was a significant interaction between GRS and the MedDiet after the follow-up period. Among subjects with a high GRS, those with a high MDS evidenced a highly significant reduction in total carotenoids, while among those with a low GRS, there was no difference associated with MDS levels. These results suggest that a higher MedDiet adherence induces beneficial effects on metabolic outcomes, which can be affected by the genetic background in some specific markers.

In spite of all the advances in sport nutrition and the importance of an adequate food intake in order to improve sport performance, both recreational and professional athletes forget frequently to include planning an optimum diet and fluid intake in their global strategy for performance. Physiological and metabolic adaptations produced as a consequence of physical exercise lead to the necessity of increasing caloric (in accordance to energy output) and protein (based on the trophic needs of the organism) intake. Likewise, paying major attention to vitamin and mineral intake, specifically B vitamins and zinc and chromium, is required, in order to optimize carbohydrate metabolism, the ultimate limiting factor for sport performance. During the training phase, 60% of calories should come from carbohydrates, protein intake should be 1.2-2 g/kg/day and athletes should follow the recommendations of the food guide pyramid. During the pre-, per- and post-competition phase the healthy aspect of the diet passes to a second level, in order to obtain good sport performance and to guarantee a fast and effective recovery. Again, carbohydrates with a high or medium glycaemic index and water are the nutrients which have to be calculated more thoroughly. In conclusion, athletes have to follow a diet that is adequate to their higher energy output and to their higher metabolic turnover. The food guide pyramid is a graphic expression which facilitates the comprehension and following of a healthy diet. In the present article, the authors introduce the pyramid adapted to the characteristics of sports nutrition, with easy-to-follow practical recommendations regarding the kind and amounts of foodstuffs that should be consumed in order to cover nutrient needs of people who exercise regularly.

Full Text Available Diet plays an important role in mammalian health and the prevention of chronic diseases such as cardiovascular disease (CVD. Incidence of CVD is low in many parts of Asia (e.g., Japan and the Mediterranean area (e.g., Italy, Spain, Greece, and Turkey. The Asian and the Mediterranean diets are rich in fruit and vegetables, thereby providing high amounts of plant bioactives including polyphenols, glucosinolates, and antioxidant vitamins. Furthermore, oily fish which is rich in omega-3 fatty acids is an important part of the Asian (e.g., Japanese and also of the Mediterranean diets. There are specific plant bioactives which predominantly occur in the Mediterranean (e.g., resveratrol from red wine, hydroxytyrosol, and oleuropein from olive oil and in the Asian diets (e.g., isoflavones from soybean and epigallocatechin gallate from green tea. Interestingly, when compared to calorie restriction which has been repeatedly shown to increase healthspan, these polyphenols activate similar molecular targets such as Sirt1. We suggest that a so-called “MediterrAsian” diet combining sirtuin-activating foods (= sirtfoods of the Asian as well as Mediterranean diet may be a promising dietary strategy in preventing chronic diseases, thereby ensuring health and healthy ageing. Future (human studies are needed which take the concept suggested here of the MediterrAsian diet into account.
Full Text Available The traditional diet in Greenland consists to a large extent of meat and organs of seal and other marine mammals, which is polluted by POPs and mercury. These substances are present in the blood of Greenlanders in concentrations well above international guidelines, and as these contaminants are suspected of having negative impacts on health, some action should be taken. On the other hand, traditional food is also an important source of health promoting micronutrients that are not provided by imported food in sufficient quantities, for example vitamin D, long chain n-3 fatty acids, and selenium, not to mention the traditional diet's function as a social glue that is perceived as important for Inuit identity in Greenland. The proportion of the total diet that comes from marine mammals is on a constant decrease, and especially children and young adults consume rather little seal and whale. The traditional food items are consequently being replaced by imported food, and among the imported food items several rather unhealthy items are popular, that is carbonated soft drinks with sugar, sweets, chips and farmed (red meat with a high content of saturated fat. Together with a decrease in physical activity, this dietary transition has resulted in a severe epidemic of overweight and diabetes. In giving advice to the public, the Greenland Board of Nutrition was therefore faced with the challenge to retain the benefits of the traditional diet while minimizing the contaminant exposure, and at the same time to counteract the effects of poor quality imported food. The Board tried to balance the known and suspected positive and negative aspects of the total diet in relation not only to physical health but to general wellbeing, and decided on 10 simple recommendations. As the consumption of traditional food becomes less prominent and as the consumption of food rich in empty calories increases, the guidelines are continuously revised and updated.

Age and acculturation may play a role in diet quality among Mexican Americans. This study examined diet quality in Mexican Americans by age and whether acculturation influences diet quality across different age groups, using data from the National Health and Nutrition Examination Survey (NHANES). Diet quality, measured by the Healthy Eating Index 2010, improved with age except in categories of dairy, sodium, and refined grains. More acculturation was associated with lower scores in overall diet quality and categories of vegetables, fruits, and sodium and empty calories across almost all ages, but higher scores in grain categories, especially in younger groups. A diet rich in fruits and vegetables but low in fat and sodium should be promoted among more acculturated Mexican Americans, and whole-grain foods should be promoted among young but less acculturated Mexican Americans.

The literature on community-based participatory research (CBPR) approaches for promoting healthy diet and nutrition and preventing and controlling obesity in African-American communities was systematically reviewed as part of the planning process for new research. CBPR studies of diet, nutrition, and weight management among African-Americans were identified from 1989 through October 31, 2015, using PubMed and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases and MeSH term and keyword searches. A total of 16 CBPR studies on healthy diet, nutrition, and weight management among African-Americans were identified; outcome evaluation results were available for all but two. Of the remaining 14 studies, 11 focused on adults, 1 on children, and 2 on both children and adults. Eight studies employed CBPR methods to address diet, nutrition, and weight management in church settings. Four had a cluster-randomized controlled design. Others had a pre-post test, quasi-experimental, or uncontrolled design. Only one study addressed four levels of the socioecological model; none addressed all five levels of the model. The studies identified in this review indicate that CBPR approaches can be effective for promoting healthy diet, nutrition, and weight management among African-American adults, but there is a need for additional studies with rigorous study designs that overcome methodologic limitations of many existing studies. There is only limited evidence for the effectiveness of CBPR approaches for promoting healthy eating and weight control among African-American children and adolescents. To address health disparities, additional CBPR studies are needed to promote healthy diet, nutrition, and weight management in African-American communities. Of particular interest are multilevel CBPR studies that include interventions aimed at multiple levels of the socioecological model.

Low socioeconomic status is associated with poor diet, food insufficiency, and poor child health. Hispanic households have disproportionately low incomes. Acculturation-related changes may augment the effects of poverty on children's diet and health. The goal was to determine the associations that acculturation, measured by parents' language use, and income have with dietary intakes and food insufficiency among Hispanic youths. Data on 2985 Hispanic youths aged 4-16 y were from the third National Health and Nutrition Examination Survey (1988-1994). Nutrient intake data were from one 24-h dietary recall. The analysis was controlled for demographic, socioeconomic, and program variables. Parents' exclusive use of Spanish was associated in bivariate analyses with differences in intakes of energy, protein, sodium, and folate and in percentages of energy from fat and saturated fat. When other factors were controlled for, less acculturation was associated with differences in intakes of energy and sodium and in percentages of energy from fat and saturated fat. Individuals in poorer households had higher intakes of energy, protein, sodium, and some micronutrients. Although not significant for all indicators of food insufficiency, consistent patterns showed that household food insufficiency decreased with less acculturation (odds ratio: 0.4; 95% CI: 0.2, 0.7 for adult meal size reduced) and increased with low income [odds ratio: 5.9 (3.0, 11.7) for not enough food and 5.4 (2.2, 13.4) for child meal size reduced]. Both acculturation and poverty have roles in children's diets and in household food insufficiency. Culturally specific public health and nutrition education should complement efforts to improve the financial security of low-income households.

Full Text Available Maternal nutrition is critical to the health of both mother and offspring, but there is a paucity of data on the nutritional adequacy of diets during pregnancy.Our objective was to identify to what extent pregnancy reduces the nutritional adequacy of the expecting mother's diet and if this nutritional gap can be resolved by simple quantitative or qualitative changes in the diet.We evaluated the observed overall nutritional adequacy of diets of French and American women of childbearing age participating in ENNS (n = 344 and NHANES (n = 563 using the probabilistic approach of the PANDiet system, resulting in a 100-point score. Then, we simulated the changes in the PANDiet scores of women of childbearing age who would remain on their diet during pregnancy. Finally, by either increasing the quantity of consumed foods or using eleven snacks recommended during pregnancy, we simulated the effect of a 150-kcal increase in the energy intake of French women.Observed PANDiet scores were equal to 59.3 ± 7.0 and 58.8 ± 9.3 points respectively in France and in the US. Simulation of pregnancy for women of childbearing age led to a decrease in nutritional adequacy for key nutrients during pregnancy and resulted in reducing PANDiet scores by 3.3 ± 0.1 and 3.7 ± 0.1 points in France and in the US. Simulated 150-kcal increases in energy intake proved to be only partially effective in filling the gap both when the quantity of food consumed was increased and when recommended snacks were used.The decrease in nutritional adequacy induced by pregnancy cannot be addressed by simply following generic dietary guidelines.

Biodiversity is key for human and environmental health. Available dietary and ecological indicators are not designed to assess the intricate relationship between food biodiversity and diet quality. We applied biodiversity indicators to dietary intake data from and assessed associations with diet quality of women and young children. Data from 24-hour diet recalls (55% in the wet season) of n = 6,226 participants (34% women) in rural areas from seven low- and middle-income countries were analyzed. Mean adequacies of vitamin A, vitamin C, folate, calcium, iron, and zinc and diet diversity score (DDS) were used to assess diet quality. Associations of biodiversity indicators with nutrient adequacy were quantified using multilevel models, receiver operating characteristic curves, and test sensitivity and specificity. A total of 234 different species were consumed, of which functional diversity, species richness (SR) showed stronger associations and better diagnostic properties with micronutrient adequacy. For every additional species consumed, dietary nutrient adequacy increased by 0.03 (P food biodiversity in diets. PMID:29255049

The present study aimed to assess whether dietetic intervention helps patients on fluid-only diets to meet their energy and protein requirements. This topic has not been previously investigated. A quasi-experimental study of 57 patients receiving fluid-only diets was conducted at The Townsville Hospital. The fluid consumption of participants was observed over 24 hours and was used to calculate total energy and protein intakes. The percentage of protein and energy requirements met was compared between patients receiving dietetic intervention and patients who were not. Patients receiving dietetic interventions met a higher percentage of their energy requirements (75.88) than the control group (18.10) based on median intakes (P diet type showed no change in effect. This study shows that dietetic intervention enabled patients on fluid-only diets to meet up to 80% more of their energy requirements and up to 95% more of their protein requirements. These results were consistent across age, BMI and fluid diet type. The significance of these differences has resulted in a change of clinical practice at the study hospital. All patients on fluid-only diets for three days or longer are now blanket referred for dietetic intervention. © 2017 Dietitians Association of Australia.

In view of the high prevalence of iron deficiency in preschool children and its consequences, this study was carried out to examine the effect of nutrition education and dietary modification on 438 two- to six-year-old nursery school children in Tehran in 1999. Sixty-two children who were judged anemic, iron-depleted, or having low iron stores were randomly allocated to "control," "dietary modification" (consuming one additional citrus fruit after lunch), and "nutrition education" (teaching the mothers proper eating patterns based on the food pyramid) groups. Food habits were surveyed, including 24-hour dietary recall and food frequency, as well as timing of consumption of special items; this survey was carried out for each child before and after intervention. After three months, blood samples were taken from the subjects. The prevalence of anemia, iron depletion, and low iron stores was 11.4, 62.8, and 15.1% respectively, with no significant differences observed in hemoglobin and percent transferrin saturation (%TS) between the groups. Mean+/-SD serum ferritin concentrations in "control," "diet modification," and "nutrition education" groups were 8.9+/-3.1, 9.5+/-3.7, and 6.9+/-2.3 microg/dL. The same figures at the end of intervention were 6.9+/-3.5, 11.2+/-5, and 10.7+/-5.9 microg/dL, respectively. Analysis of variance showed ferritin concentrations to be significantly different, in that there was a reduction in the control and elevation in the nutrition education groups. There was no significant difference in %TS before and after the intervention. During three months of intervention, changes in frequency of fruit and fruit juice intake after the meals in nutrition education and diet modification groups were significantly correlated to serum ferritin alteration. Frequency of fruit juice intake (rich in vitamin C) after meals (at least five times a week) can significantly increase serum ferritin within three months. Therefore, educating mothers of iron
Full Text Available In this work, we analysed the effect of aguamiel (sap from Agave salmiana on haematic biometry in rabbits as well as its antioxidant activity with the objective of determining its nutritional value. Nine male Landrace 55-day-old rabbits were sorted into three groups of three rabbits each, which had access to fresh aguamiel, boiled aguamiel and water instead of aguamiel. Commercial rabbit food was supplied ad libitum to each experimental unit. Fresh aguamiel promoted weight increases of about 13% by the seventh week. Haemoglobin counts increased by 4.5% and 9% when rabbits were fed with fresh and boiled aguamiel, respectively. Haematocrit counts increased from 2.6% to 5.3%. Mean corpuscular volume did not show a change. Mean corpuscular haemoglobin significantly increased up to 12% above that previously reported on rabbits. Observed Fe (fixed to transferrin, transferrin and ferritin content increased slightly when fresh aguamiel was included in the diet, as compared to the control. In bone, Fe increased 79.3% (boiled aguamiel while P increased 23.6% (fresh aguamiel. In antioxidant activity determination, the aguamiel showed 20% with respect to that found in coffee and/or grape juice (commercial beverages with a high antioxidant capability, 226.2 µmol gallic acid equivalent and 35.1 mg ascorbic acid in 250 mL, respectively. These results showed that aguamiel is an innocuous beverage to feed animals, conferring some beneficial properties, and it could be considered as a nutraceutical product.

The key to improving the health and well-being of Native Hawaiians is to understand the historical events that have caused change to their diet and nutrition, and identify the connection between food, life, and the land. The purpose of this article is to (a) present a review of the literature addressing nutrition and diet as it relates to health and well-being of Native Hawaiian kūpuna (elders) and (b) identify limitations and gaps to promote future research. This systematic literature review focused on 29 studies. Native Hawaiians have the highest body mass index levels, highest daily energy (kilocalorie) intake, and lowest multivitamin use. They have the highest prevalence of diabetes and hypertension compared with Whites. Traditional Hawaiian diet programs and family support were beneficial to improving health and well-being. Future research of traditional Hawaiian diet programs and revitalization of the culture may lead to improving the health and well-being of Native Hawaiians.

Lack of food composition data, recipe information and portion sizes for ethnic foods are commonly reported problems for dietary assessment of ethnic minority groups. One of the main aims of this study was to use food composition data to validate portion sizes, identify important sources of nutrients and describe the characteristics of the South Asian diet. The top five ethnic foods containing highest levels of selected nutrients were lamb balti (3mg/100g iron), lamb kebab (3.2mg/100g zinc), mixed dhal (62μg/100g folate), fish curry (1.4μg/100g vitamin D), ghee (968μg/100g retinol) and toor dhal (9.1g/100g dietary fibre). Typical adult South Asian diets included traditional cereals (chapatti, rice and paratha) and low consumption of meat dishes; with vegetable curries contributing most towards energy intake. A higher consumption of full fat milk and fruit juices by toddlers and school children were observed when compared with the National Diet and Nutrition Survey of the UK. Copyright © 2013.

Biomarkers for cardiometabolic risk (CMR) factors would be important tools to maximize the effectiveness of dietary interventions to prevent cardiovascular diseases. Thus, the aim of this work was to analyze stearoyl-CoA desaturase (SCD) indexes and n-6/n-3 fatty acids (FA) ratio as biomarkers of CMR induced by feeding rabbits on high fat diets (HFDs). Rabbits were fed either regular diet or 18 % fat in regular diet (HFD) or 1 % cholesterol diet (HD) or diet containing 1 % cholesterol and 18 % fat (HFD-HD) during 6 weeks. Body weights (BW), blood pressure, visceral abdominal fat (VAF) and glucose tolerance test were determined. Total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), triglycerides (TG), fasting glucose (FG), and FA levels from plasma were measured. SCD indexes were calculated as product/precursor ratios of individual FA. BW was similar in all diet groups. HD increased TC, LDL-C, HDL-C, and TG. HFD increased TG, VAF and FG, and decreased HDL-C. The addition of HFD to HD joined to dyslipidemia increased VAF and FG. SCD indexes were increased and n-6/n-3 was unchanged in HD. SCD indexes were reduced and n-6/n-3 FA ratio was increased in HFD and HFD-HD. CMR factors were correlated positively with n-6/n-3 FA ratio. Although VAF had a stronger correlation with n-6/n-3 FA ratio than with SCD indexes, VAF was associated independently to both markers. HFD simulating lipid composition of the average Western-style diet induced experimental rabbit models of normal-weight metabolic syndrome (MS). SCD indexes and n-6/n-3 were modified according to the type of dietary fat. Considering that VAF and CMR factors appear to be stronger associated to n-6/n-3 FA ratio than to SCD indexes, n-6/n-3 FA ratio may be a better biomarker of MS and CMR in normal-weight subjects than SCD indexes.

Supplying adequate human nutrition within ecosystem carrying capacities is a key element in the global environmental sustainability challenge. Life cycle assessment (LCA) has been used effectively to evaluate the environmental impacts of food production value chains and to identify opportunities for targeted improvement strategies. Dietary choices and resulting consumption patterns are the drivers of production, however, and a consumption-oriented life cycle perspective is useful in understanding the environmental implications of diet choices. This review identifies 32 studies that use an LCA framework to evaluate the environmental impact of diets or meals. It highlights the state of the art, emerging methodological trends and current challenges and limitations to such diet-level LCA studies. A wide range of bases for analysis and comparison (i.e., functional units) have been employed in LCAs of foods and diet; we conceptually map appropriate functional unit choices to research aims and scope and argue for a need to move in the direction of a more sophisticated and comprehensive nutritional basis in order to link nutritional health and environmental objectives. Nutritional quality indices are reviewed as potential approaches, but refinement through ongoing collaborative research between environmental and nutritional sciences is necessary. Additional research needs include development of regionally specific life cycle inventory databases for food and agriculture and expansion of the scope of assessments beyond the current focus on greenhouse gas emissions.

The study evaluated the partial substitution of soybean meal by faba beans (18%) or peas (20%) as additional protein sources in diets destined for typical Italian heavy pig production. It compared animal performances, meat quality, the presence of residual anti-nutritional factors (ANF) and phytoestrogens in plasma and meat and the possible effects on pig health, by evaluating oxidative, inflammatory and pro-atherogenic markers. The results showed that the productive performances, expressed as body weight and feed conversion ratio, of pigs fed with faba bean and pea diets were similar to those of pigs fed only the soybean meal. Meat quality of pigs fed with the three diets was similar in colour, water-holding capacity, tenderness and chemical composition. Despite the higher levels of phytoestrogen in the plasma of pigs fed only the soybean meal, phytoestrogen concentration in the muscle was equivalent to that of animals fed diets with faba beans, whereas pigs fed a diet with peas showed a lower concentration. Inflammation and pro-atherogenic parameters did not show significant differences among the three diets. Overall, the partial substitution of soybean meal by faba beans appears more interesting than with peas, particularly in relation to the higher amount of polyphenols in the diet and the highest concentration of phytoestrogens found in the plasma and muscle of animals, while the pyrimidine anti-nutritional compounds present in the diet did not appear to accumulate and had no effect on the growth performance of animals.

Improving diet and lifestyle is a critical component of the American Heart Association's strategy for cardiovascular disease risk reduction in the general population. This document presents recommendations designed to meet this objective. Specific goals are to consume an overall healthy diet; aim for a healthy body weight; aim for recommended levels of low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglycerides; aim for normal blood pressure; aim for a normal blood glucose level; be physically active; and avoid use of and exposure to tobacco products. The recommendations are to balance caloric intake and physical activity to achieve and maintain a healthy body weight; consume a diet rich in vegetables and fruits; choose whole-grain, high-fiber foods; consume fish, especially oily fish, at least twice a week; limit intake of saturated fat to foods with added sugars; choose and prepare foods with little or no salt; if you consume alcohol, do so in moderation; and when you eat food prepared outside of the home, follow these Diet and Lifestyle Recommendations. By adhering to these diet and lifestyle recommendations, Americans can substantially reduce their risk of developing cardiovascular disease, which remains the leading cause of morbidity and mortality in the United States.

The lifetime prevalence of kidney stones is around 10 % and incidence rates are increasing. Diet may be an important determinant of kidney stone development. Our objective was to investigate the association between diet and kidney stone risk in a population with a wide range of diets. This association was examined among 51,336 participants in the Oxford arm of the European Prospective Investigation into Cancer and Nutrition using data from Hospital Episode Statistics in England and Scottish Morbidity Records. In the cohort, 303 participants attended hospital with a new kidney stone episode. Cox proportional hazards regression was performed to calculate hazard ratios (HR) and their 95 % confidence intervals (95 % CI). Compared to those with high intake of meat (>100 g/day), the HR estimates for moderate meat-eaters (50-99 g/day), low meat-eaters (<50 g/day), fish-eaters and vegetarians were 0.80 (95 % CI 0.57-1.11), 0.52 (95 % CI 0.35-0.8), 0.73 (95 % CI 0.48-1.11) and 0.69 (95 % CI 0.48-0.98), respectively. High intakes of fresh fruit, fibre from wholegrain cereals and magnesium were also associated with a lower risk of kidney stone formation. A high intake of zinc was associated with a higher risk. In conclusion, vegetarians have a lower risk of developing kidney stones compared with those who eat a high meat diet. This information may be important to advise the public about prevention of kidney stone formation.

Intention-to-treat and per-protocol analyses provide complementary information about the usefulness of therapies. While intention-to-treat analyses of trials that tested low-protein diets remain debated, per-protocol analyses of the same trials show that low protein intake actually reduces the risk of kidney failure. Per-protocol analyses are notoriously open to bias but intention-to-treat analyses are less immaculate than commonly realized because they critically depend on adherence to the treatment being tested and therefore may not be directly relevant for informing clinical decisions when different degrees of adherence to therapy occur. Over the last 20 years new statistical techniques censoring patients at the time when they become uncompliant and that adjust for confounding attributable to incomplete adherence, i.e. for prognostic factors that predict adherence to treatment, have been developed. These techniques can be usefully applied to reanalyse the Modification Diet in Renal Disease (MDRD) and other trials. Intensive surveillance of patients on a low-protein diet is fundamental for early detection of malnutrition. However, the resources demanded by such surveillance are likely superior to the actual dietitians workforce dedicated to follow-up of the chronic kidney disease (CKD) population. Surveillance efforts may perhaps be preferentially devoted to preselected patients, i.e. patients that maintain good compliance and an adequate metabolic and nutritional status, while patients who are resistant to educational efforts and show persisting uncompliance may be reallocated to a diet with a higher protein content, which poses a lower risk of malnutrition and other adverse health outcomes.

The Cayumapu River's black-necked swan population in southern Chile lost its main dietary item, Egeria densa, during an environmental crisis which occurred in 2004 in the Carlos Andwanter Nature Sanctuary. The main goal of this study was to test the effect of diet on the physiologic response to this new ecologic challenge. The results revealed that the new diet of this population was composed primarily of roots and sedimentary microalgae, with chemical and energetic content similar to the diet of the control population. Nevertheless, the mean body mass of the Cayumapu River swans was 25% lower than that of control birds. In addition, the biochemical and hematologic profiles of the study population were indicative of malnutrition and a hyperferremic, hyperphosphatemic, and lymphopenic condition. Liver enzyme activities did not support that the malnutrition was a secondary consequence of liver dysfunction, as is expected under hemochromatosis or environmental toxics exposure.

Little is known about the fatty acid composition of foods eaten by wild primates. A total of 18 staple foods that comprise 97% of the annual dietary intake of the mountain gorilla (Gorilla beringei) were analyzed for fatty acid concentrations. Fruits and herbaceous leaves comprise the majority of the diet, with fruits generally having a higher mean percentage of fat (of dry matter; DM), as measured by ether extract (EE), than herbaceous leaves (13.0% ± SD 13.0% vs. 2.3 ± SD 0.8%). The mean daily EE intake by gorillas was 3.1% (DM). Fat provided ≈14% of the total dietary energy intake, and ≈22% of the dietary non-protein energy intake. Saturated fatty acids accounted for 32.4% of the total fatty acids in the diet, while monounsaturated fatty acids accounted for 12.5% and polyunsaturated fatty acids (PUFA) accounted for 54.6%. Both of the two essential PUFA, linoleic acid (LA, n-6) and α-linolenic acid (ALA, n-3), were found in all of the 17 staple foods containing crude fat and were among the three most predominant fatty acids in the diet: LA (C18:2n-6) (30.3%), palmitic acid (C16:0) (23.9%), and ALA (C18:3n-3) (21.2%). Herbaceous leaves had higher concentrations of ALA, while fruit was higher in LA. Fruits provided high amounts of fatty acids, especially LA, in proportion to their intake due to the higher fat concentrations; despite being low in fat, herbaceous leaves provided sufficient ALA due to the high intake of these foods. As expected, we found that wild mountain gorillas consume a diet lower in EE, than modern humans. The ratio of LA:ALA was 1.44, closer to agricultural paleolithic diets than to modern human diets. © 2013 Wiley Periodicals, Inc.

Feeding highly fermentable diets to ruminants is one strategy to increase energy intake. The increase in short-chain fatty acid (SCFA) production and reduced ruminal pH associated with highly fermentable diets imposes a challenge to the metabolism and the regulation of intracellular pH homeostasis of ruminal epithelia. The ruminal epithelia respond to these challenges in a coordinated manner. Whereas the enlargement of absorptive surface area is well documented, emerging evidence at the mRNA and transporter and enzyme activity levels indicate that changes in epithelial cell function may be the initial response. It is not surprising that gene expression analysis has identified pathways involved in fatty acid metabolism, ion transport, and intracellular homeostasis to be the pathways dominantly affected during adaptation and after adaptation to a highly fermentable diet. These findings are important because the intraepithelial metabolism of SCFA, particularly butyrate, helps to maintain the concentration gradient between the cytosol and lumen, thereby facilitating absorption. Butyrate metabolism also controls the intracellular availability of butyrate, which is widely regarded as a signaling molecule. Current data indicate that for butyrate metabolism, 3-hydroxy-3-methylglutaryl-CoA synthase and acetyl-CoA acetyltransferase are potential regulatory points with transient up- and downregulation during diet adaptation. In addition to nutrient transport and utilization, genes involved in the maintenance of cellular tight junction integrity and induction of inflammation have been identified as differentially expressed genes during adaptation to highly fermentable diets. This may have important implications on ruminal epithelial barrier function and the inflammatory response often associated with subacute ruminal acidosis. The objective of this review is to summarize ruminal epithelial adaptation to highly fermentable diets focusing on the changes at the enzyme and
Full Text Available The effect of replacing maize fraction of the diet of growing snails partially or wholly with bread waste (BW on performance characteristics and cost benefits was studied for 12 weeks. A total of 120 growing snails (Archachatina marginata of mean weight 83.67 ± 3.5g of about 3 months of age were randomly allotted to 4 dietary treatments, BW1, BW2, BW3 and BW4 in which maize fraction of the diet was replaced at 0, 50, 75 and 100% with BW respectively, in a completely randomized design replicated 3 times. The parameters measured were feed intake, weight gain, shell length, width and thickness. Feed conversion ratio and cost/weight gain were calculated. The results showed that significant differences were not observed in the mean total feed intake, weight gain and shell increment (P>0.05. The results also revealed that dietary treatments had no significant influence on the dressing percentage (P>0.05 which varied between 41.25 and 41.28%. The total feed cost and cost per weight reduced as the level of BW in the diet increased from 0 to 100%. The highest cost/ weight gain (CW of N223.2 was recorded in diet containing 0% BW while the lowest CW was recorded in diet containing 100%BW. Based on the present results maize fraction of snail’s diet could be replaced with bread waste up to 100% at reduced cost without any adverse effect on performance of growing snails.

Migration has an influence on health behavior and food intake. Dietary variety is a key component to high-quality diets because a single food item does not contain a variety of nutrients and may not reflect nutritional adequacy. We aimed to compare the dietary diversity scores (DDS), food variety scores (FVS), and nutrient adequacy levels of married Filipino immigrant women in Korea to those of Korean women. We matched the data of 474 participants aged 20-57 years from the Filipino Women's Diet and Health Study (FiLWHEL) by age category with those of married Korean women randomly selected from the Korea National Health and Nutrition Examination Survey (KNHANES). Dietary information in FiLWHEL and KNHANES were assessed through the 24-hour recall method. We calculated the DDS by summing the number of eleven food groups consumed (DDS 10 g if they consumed at least 10 g/day; DDS all if they consumed any amount) and the FVS by counting the number of food items consumed. For nutrient adequacy, we calculated the probability of adequacy (PA) and intake below the estimated average requirement (EAR). Filipino women had a lower DDS and FVS in comparison to Korean women. The means (±SDs) of DDS 10 g, DDS all, and FVS for Filipino women versus Korean women were 6.0 (±1.6) versus 6.8 (±1.5) (p Filipino women than for Korean women. The mean probability of adequacy (MPA) of nutrient intake of the nine selected nutrients was lower for Filipino women in comparison to Korean women. The mean (±SD) was 0.55 (±0.28) versus 0.66 (±0.26), respectively. Our findings showed that married Filipino immigrant women in Korea had lower dietary variety scores in comparison to Korean women. This was reflected in their nutritional adequacy. Nutrition education focusing on the promotion of eating a variety of foods may be needed for Filipino immigrant women in Korea.

Dietary diversity is associated with nutrient adequacy and positive health outcomes but indicators to measure diversity have focused primarily on consumption, rather than sustainable provisioning of food. The Nutritional Functional Diversity score was developed by ecologists to describe the contribution of biodiversity to sustainable diets. We have employed this tool to estimate the relative contribution of home production and market purchases in providing nutritional diversity to agricultural households in Malawi and examine how food system provisioning varies by time, space and socio-economic conditions. A secondary analysis of nationally representative household consumption data to test the applicability of the Nutritional Functional Diversity score. The data were collected between 2010 and 2011 across the country of Malawi. Households (n 11 814) from predominantly rural areas of Malawi. Nutritional Functional Diversity varied demographically, geographically and temporally. Nationally, purchased foods contributed more to household nutritional diversity than home produced foods (mean score=17·5 and 7·8, respectively). Households further from roads and population centres had lower overall diversity (PFunctional Diversity score is an effective indicator for identifying populations with low nutritional diversity and the relative roles that markets, agricultural extension and home production play in achieving nutritional diversity. This information may be used by policy makers to plan agricultural and market-based interventions that support sustainable diets and local food systems.

The aims of the study were to evaluate the quality of the diet of nondialysis-dependent patients with chronic kidney disease and to investigate the impact of dietary counseling in the quality of the diet of these patients. In the cross-sectional analysis, 3-day food records of 100 nondialysis-dependent patients with chronic kidney disease patients, in the first visit to the renal dietitians, were evaluated using the Diet Quality Index (DQI). Under-reporters were excluded. DQI is comprised by 10 components: 6 are food groups (fruits, vegetables, cereals, milk and dairy, meats and eggs, and legumes); 3 are nutrients (total fat, sodium, and cholesterol), and the last one is the diet variety. Each component is scored from 0 to 10, according to the adequacy of the Brazilian dietary guideline, and an overall score ranging from 0 (poor) to 100 (good) is obtained. In a subsample of 44 patients, a prospective analysis was performed to compare the DQI and its components before and after dietary counseling. The median DQI score was 68.6 (62.3-75.6; interquartile range), which means that most of the patients (92%) had a diet that "needs improvement" (DQI between 50 and 80 points). The DQI components with the lowest scores (lower adequacy) were sodium (0.0 [0.0-0.9]), dairy (3.9 [2.1-6.0]), and vegetables (6.0 [2.8-9.5]), whereas meat/egg, legumes, and cholesterol had the highest scores. Vegetables, legumes, and diet variety components were significantly lower in the lower tertiles of DQI. After a median follow-up of 25.0 (17.0-35.8) months comprising 6 (5-10) visits to the dietitian, energy, protein, and micronutrients intake were significantly reduced. The dietary counseling did not improve the overall DQI (after: 69.0 [69.0-74.8]; P = .95) and, a significant reduction in the score of legumes (from 10.0 [2.7-10.0] to 7.8 [4.7-10.0], P = .00) and diet variety (from 7.0 [5.3-10.0] to 6.0 [4.0-9.0], P = .02) components were observed.

Prader-Willi Syndrome (PWS) is a genetic disorder caused by the lack of expression of paternal alleles in the proximal region of the long arm of chromosome 15. Low inhibitory control and hyperphagia are two of the most severe neurobehavioral symptoms of the syndrome. The aim of the present study was to assess the efficiency of nutritional training program with the use hypocaloric diet for weight control in a group of five children and adolescents with PWS. The intervention program consisted of 10 sessions for parents' orientation during 8months. Patients had their anthropometric measures assessed (weight, height and body mass index - BMI). The main results indicate weight maintenance, height increase, and BMI decrease after intervention. These results were considered indicators of the program's efficiency.

The results of an analysis of gorilla diet in the Lopé Reserve, Gabon are presented. Samples were assayed for nutrients and plant secondary compounds (total phenols, condensed tannins and alkaloids) in an attempt to explain gorilla food choice. The diet is the most diverse so far analysed for gorillas; it seems to be a balance between sugary fruit, proteinaceous leaves, and relatively fibrous stems. Most fruits and herbaceous stems are succulent, but some drier, fibrous fruit and bark is also consumed. Seeds are another component of the diet, including unripe ones. Fruit, seeds, leaves and bark may all contain very high levels of total phenols and condensed tannins; but all herbaceous stems assayed contain low levels of these compounds. Alkaloids are not apparently a significant component of gorilla foods, and may be avoided. Gorillas at Lopé tend to avoid fatty fruit, and select leaves which are high in protein and low in fibre compared to the general vegetation. When fruit and preferred young leaves are scarce, proteinaceous barks and mature leaves, and sugary pith, are important sources of nutrients. We conclude that gorillas exploit the broad frugivore niche in West African lowland forests, and are part of the frugivore community there. What distinguishes them is their ability to eat large fibrous fruit, mature leaves and stems, and to overcome high levels of phenolics (we use "phenolics" as an umbrella term for both total phenols and condensed tannins). Gorilla diet at Lopé overlaps greatly with that of sympatric, frugivorous, primates, and resembles more closely that of chimpanzees than it does gorilla diet studied elsewhere in Africa.

The present experiment tested a dietary supplementation with linseed oil and selenium to growing rabbits. The basal diet (B) contained 3% sunflower oil, while it was substituted with 3% linseed oil in the experimental feed (S). The selenium (Se) content of the two diets was 0.10 vs. 0.46 mg/kg. Rabbits were fed with B diet from the age of 18 days. One group was fed with the B diet until 11 weeks of age (group B), whereas the experimental groups were fed with S diet for 1, 2, 3 or 4 weeks (groups S1, S2, S3 and S4, respectively), before slaughtering (11 weeks of age). Live performance and carcass traits of rabbits, fatty acid (FA) profile and selenium content of their hind leg (HL) and Longissimus thoracis et lumborum (LTL) meat were considered in this study. In addition, the effect of two different cooking methods on the nutritional value of the enriched HL meat was also assessed. The tested dietary supplementation only minimally affected the live performance and carcass traits of rabbits. The S supplementation significantly reduced the Σ n-6 FA and increased the Σ n-3 FA of the HL meat and LTL meat, compared to the B diet (p meat and LTL meat of S fed rabbits were significantly enriched in Se reaching a twofold increase in both meat cuts (p meat. The heat treatment affected cooking loss, Se and vitamin E contents as well as the oxidative status of the HL meat (p < 0.001), with the different cooking methods providing different results. In addition, even if the beneficial C20:5 n-3 and C22:6 n-3 decreased with cooking, the n-6/n-3 ratio remained unaffected.

Full Text Available Background : Growing up milks (GUM are milk-based drinks with added vitamins and minerals intended for children aged 12–36 months. Few data are available on the consumption of GUM and their role in the diets of young children. Objective : To determine the nutritional adequacy of two groups of 12–24-month-old Irish children by type of milk consumption (consumers or non-consumers of GUM. Design : Using data from a cross-sectional study of Irish children, the National Pre-School Nutrition Survey (2010–2011, two groups of children were defined. The groups included children aged 12–24 months with an average daily total milk intake of at least 300 g and consuming GUM (≥100 g/day together with cow's milk (n=29 or cow's milk only (n=56. Results : While average total daily energy intakes were similar in both consumers and non-consumers of GUM, intakes of protein, saturated fat, and vitamin B12 were lower and intakes of carbohydrate, dietary fibre, iron, zinc, vitamins C and D were higher in consumers of GUM. These differences in nutrient intakes are largely attributable to the differences in composition between GUM and cow's milk. For both consumers and non-consumers of GUM, intakes of carbohydrate and fat were generally in line with recommendations while intakes of protein, dietary fibre and most micronutrients were adequate. For children consuming cow's milk only, high proportions had inadequate intakes of iron and vitamin D; however, these proportions were much lower in consumers of GUM. Conclusions : Consumption of GUM reduced the risk of inadequacies of iron and vitamin D, two nutrients frequently lacking in the diets of young children consuming unfortified cow's milk only.

This study examined the association between nutritional awareness and diet quality, as indicated by energy density, dietary diversity and adequacy to achieve dietary recommendations, while considering the potentially important role of socioeconomic status (SES). Data were derived from 1351 subjects, aged 18-69 years and enrolled in the ORISCAV-LUX study. Energy density score (EDS), dietary diversity score (DDS) and Recommendation Compliance Index (RCI) were calculated based on data derived from a food frequency questionnaire. Nutritional awareness was defined as self-perception of the importance assigned to eating balanced meals, and classified as high, moderate, or of little importance. Initially, a General Linear Model was fit that adjusted for age, sex, country of birth, and body mass index (BMI). Furthermore, simultaneous contributions to diet quality of individual-level socioeconomic factors, education, and household income were examined across levels of nutritional awareness. Attributing high importance was associated inversely with energy density (p = 0.02), positively with both dietary diversity (p diet quality, with a minor component of variance explained by improved income. The impact of nutritional awareness on diet quality seems to be a promising area for both health promotion and health policy research.

Full Text Available Os efeitos de cinco fontes de fibra sobre a produção, composição química e a contribuição nutritiva dos cecotrofos em termos de matéria seca e proteína bruta foram estudados. Quarenta coelhas da raça Nova Zelândia branco foram alojadas em gaiolas metabólicas, por 12 dias, para adaptação às dietas. No 13º dia, para evitar a coprofagia, os animais receberam um colar de madeira por um período de 24 horas, procedendo-se à coleta dos cecotrofos de duas em duas horas. A dieta padrão tinha como principal fonte de fibra o feno de alfafa. As outras dietas foram caracterizadas pela substituição isométrica do feno de alfafa por feno de guandu (Cajanus cajan, palha de feijão, palha e sabugo de milho branco e o feno coast-cross (Cynodon dactylon. Foi observado efeito do tipo de dieta sobre a composição química dos cecotrofos e o teor de PB ingerida por cecotrofia, porém a produção de cecotrofos não diferiu entre dietas.The effects of five fiber sources on the production, chemical composition and cecotrophes nutritive contribution on dry matter and crude protein base were studied. Forty White New Zealand female rabbits were housed in metabolic cage for 12 days to adaptation to the diets. In the 13th day, to prevent coprophagy, the animals received a necklace of wood for a period of 24 hours, and the cecotrophes were collected every two hours. The standard diet had the alfalfa hay as a mainly fiber source. The other diets were characterized by isometric replacement of alfalfa hay by pigeon pea hay (Cajanus cajan, bean straw, white corn with cob and husks and coast-cross hay (Cynodon dactylon. Effect of diet type on cecotrophes chemical composition and crude protein content ingested by cecotrophy was observed, however the cecotrophes production was not different among diets.
Full Text Available Moringa has been acclaimed to be beneficial especially in livestock production. Its leaves and green fresh pods are said to be rich in carotene and ascorbic acid with a good profile of amino acids while its twigs are reported to be very palatable to ruminants and have appreciable crude protein levels. However, Moringa oleifera leaf meal (MOLM has been observed to contain higher pepsin and total soluble protein than other parts of the plant which makes it more suitable to monogastric animals. MOLM has been widely used in poultry production but with limited use in rabbits� diets; hence this study was conducted to determine the performance of weaner rabbits fed graded levels of MOLM. A total of 48 unsexed weaner rabbits of mean initial weight of 744.56�29.25 g were assigned to 4 experimental diets, namely T1, T2, T3 and T4 containing 0%, 15%, 30% and 45% MOLM, respectively, having 3 replicates and 4 animals per replicate. The results showed that the dry matter intake of T1-T4 ranged 53.17 - 55.31g/day. Though not significant, highest crude protein digestibility coefficient was recorded for experimental animals on diet T4 (71.36% followed by diets T1 (69.67%, T2 (69.17%, T3 (68.25%, respectively. The keel length for T1, T2, T3, and T4 rabbits were 225.39, 201.64, 246.66 and 217.26cm, respectively Rabbits fed 30% MOLM were found to be most profitable numerically (N1320.10 while the least profit was obtained with 0% MOLM with N1305.40. Hence, it can be concluded that Moringa oleifera leaf meal (MOLM can replace soya bean meal up to 45% in the nutrition of weaner rabbits.

Vultures are central-place foragers and need to optimize their foraging behaviour to offset travel costs by increasing their energy gain. This process is more obvious in certain vulture species that do not feed their young by regurgitation and so must carry food items back to the nest. The Bearded Vulture Gypaetus barbatus is the only species with a bone-diet based. We analysed the chemical composition of bones and the age-related changes in their nutritive value to assess the differences in energy content between bones of differing age, body part and species. We found differences between specific anatomical parts, species and the age of the bones. Fresh bones contain 108% as much energy as fresh meat and, interestingly, dry bones retain 90% of the protein found in fresh bones. Dry femurs weighing 140 g retain enough protein to be comparable to 111 g of fresh meat, in energy terms. Compared to meat-eating species, the specialized osteophagous diet of the Bearded Vulture seems to have certain advantages. A better understanding of nutrient levels in food remains could help to improve theoretical foraging models, assist in conservation management, and even improve our understanding of the use of bones by early hominids.

To compare the energy and macronutrient intake responses to equivalent energy deficits induced by diet (food restriction) and exercise in adolescents with obesity. Fourteen 12-15years old obese adolescents completed three experimental conditions (08:00am to 07:30pm) in a randomized crossover design: i) control session (CON); ii) diet-induced 25% energy depletion (Def-EI), iii) and an exercise-induced 25% energy depletion (Def-EX). The sessions order was either CON/Def-EI/Def-EX or CON/Def-EX/Def-EI as the deficit corresponded to 25% of the energy ingested at lunch on the control day (CON) and was imposed either by exercise (Def-EX) or diet (Def-EI). Ad libitum EI and macronutrients preferences were assessed at dinner and appetite sensations assessed using visual analogue scales. Mean BMI was 36.6±5.0kg/m 2 (z-BMI: 2.40±0.29). The individually calibrated 25% energy deficit represented 254±92kcal. Ad libitum EI was significantly higher during both Def-EX (971±225kcal) and Def-EI (949±246kcal) compared with CON (742±297) (pexercise and the control session (EI Def-EX - EI CON) (r=-0,643 pexercise- or diet-induced energy deficits could lead to similar EI compensation in obese adolescents but this EI compensation might be influenced by the magnitude of the deficit.

Full Text Available Oxidative stress is currently suggested to play as a pathogenesis in the development of diabetes mellitus. There are many reports indicating the changes in parameters of oxidative stress in diabetes mellitus. The role of dietary management in diabetes mellitus is to provide a proper balance of total nutrients while meeting the special dietary needs of the patient. Complex carbohydrates and dietary fiber help to delay the absorption of glucose from the intestinal tract and minimize postprandial fluctuation of glucose. The present study was designated to evaluate the effect of special antidiabetic diet treatment upon oxidative stress parameters in the initial stages of the development of diabetes. The findings of the present study suggest that special diet formula useful for prevention of progressive hyperglycaemia in aged provoked diabetes in dogs could not restore the imbalance of cellular defense mechanism provoked by streptozotocin. Soluble fiber in the diet may also prolong gastrointestinal transit time, allow greater water absorption, and promote the production of short chain fatty acids which nourish the intestinal mucosa.

The world has experienced a marked shift in the global BMI distribution towards reduced undernutrition and increased obesity. The collision between human biology, shaped over the millennia and modern technology, globalization, government policies and food industry practices have worked to create far-reaching energy imbalance across the globe. A prime example is the clash between our drinking habits and our biology. The shift from water and breast milk as the only beverages available, to a vast array of caloric beverages was very rapid, shaped both by our tastes and aggressive marketing of the beverage industry. Our biology, shaped over millennia by daily consumption of water and seasonal availability of food, was not ready to compensate for the liquid energies. Other dietary changes were similarly significant, particularly the shift towards increased frequency of eating and larger portions. The roles of the food and beverage production, distribution and marketing sectors in not only shaping our diet but also accelerating these changes must be understood. Apart from the role of beverages, there is much less consensus about the role of various components of our diet in energy imbalance. Understanding the determinants of change in the key components of our diet through an array of research provides insights into some of the options we face in attempting to attain a great balance between energy intake and expenditures while creating an overall healthier dietary pattern. A few countries are systematically addressing the causes of poor dietary and physical activity patterns and high energy imbalance. PMID:21092363

Evidence on the associations of dietary patterns with cognition in children is limited. Therefore, we investigated the associations of the Baltic Sea Diet Score (BSDS) and the Dietary Approaches to Stop Hypertension (DASH) score with cognition in children. The present cross-sectional study sample included 428 children aged 6-8 years (216 boys and 212 girls). The BSDS and the DASH score were calculated using data from 4 d food records, higher scores indicating better diet quality. Cognition was assessed by the Raven's Coloured Progressive Matrices (CPM) score, a higher score indicating better cognition. Among all children, the BSDS (standardised regression coefficient β = 0·122, P =0·012) and the DASH score (β = 0·121, P =0·015) were directly associated with the Raven's CPM score. Among boys, a lower BSDS (β = 0·244, Pcognition. In conclusion, a poorer diet quality was associated with worse cognition in children, and the relationship was stronger in boys than in girls.

Special Operations Forces (SOF) Soldiers deploy frequently and require high levels of physical and cognitive performance. Nutritional status is linked to cognitive and physical performance. Studies evaluating dietary intake and nutritional status in deployed environments are lacking. Therefore, this study assessed the effects of combat deployment on diet quality and serum concentrations of nutritional status markers, including iron, vitamin D, parathyroid hormone (PTH), glucose, and lipids, among elite United States (U.S.) Army SOF Soldiers. Changes from baseline to post-deployment were determined with a repeated measure within-subjects design for Healthy Eating Index-2010 (HEI-2010) scores, intake of foods, food groups, key nutrients, and serum nutritional status markers. Dietary intake was assessed with a Block Food Frequency Questionnaire. The association between post-deployment serum 25-hydroxy vitamin D (25-OH vitamin D) and PTH was determined. Analyses of serum markers were completed on 50 participants and analyses of dietary intake were completed on 33 participants. In response to deployment, HEI-2010 scores decreased for total HEI-2010 (70.3 ± 9.1 vs. 62.9 ± 11.1), total fruit (4.4 ± 1.1 vs. 3.7 ± 1.5), whole fruit (4.6 ± 1.0 vs. 4.2 ± 1.4), dairy (6.2 ± 2.7 vs. 4.8 ± 2.4), and empty calories (14.3 ± 3.2 vs. 11.1 ± 4.5) (P ≤ 0.05). Average daily intakes of foods and food groups that decreased included total dairy (P < 0.01), milk (P < 0.01), and non-juice fruit (P = 0.03). Dietary intake of calcium (P = 0.05) and vitamin D (P = 0.03) decreased. PTH increased from baseline (3.4 ± 1.6 vs. 3.8 ± 1.4 pmol/L, P = 0.04), while there was no change in 25-OH vitamin D. Ferritin decreased (385 ± 173 vs. 354 ± 161 pmol/L, P = 0.03) and soluble transferrin receptor increased (16.3 ± 3.7 vs. 17.1 ± 3.5 nmol/L, P = 0.01). There were no changes in glucose or lipids.

We developed a WASHOKU-modified DASH diet named DASH-JUMP. We previously reported the hypotensive effect of the DASH-JUMP diet in Japanese participants with untreated high-normal Blood Pressure (BP) or stage 1 hypertension. We aim to introduce the DASH-JUMP diet worldwide as a new lifestyle medicine. Accordingly, we prospectively assessed the nutritional characteristics of the DASH-JUMP diet. Participants were treated with the DASH-JUMP diet for 2 months. Then, for 4 months after the intervention, they consumed their usual diets. We conducted a nutritional survey using the FFQg nutrient questionnaire at baseline and after 1, 2, 3, and 6 months. We received completed questionnaires from 55 participants (28 men and 27 women; mean age 54.2 ± 8.0 years) and analyzed them. The DASH-JUMP diet is rich in green-yellow vegetables, seaweed, milk, and mushrooms, while it has low contents of meat, eggs, confectionery, oils and fats, pickles, shellfish boiled in sweetened soy sauce, and fruits. Nutrients significantly associated with the observed change in systolic BP were niacin (P = 0.005) and carbohydrate (P = 0.033). The results of the FFQg questionnaire revealed that participants who had an increased BP at 1 month after ceasing the intervention had eating habits that broadly imitated the DASH-JUMP diet at 4 months after ceasing the intervention. Therefore, the systolic and diastolic BP values at 4 months after ceasing the intervention decreased significantly compared to those at baseline. The DASH-JUMP diet may represent a new lifestyle medicine for reducing hypertension. Copyright© Bentham Science Publishers; For any queries, please email at firstname.lastname@example.org.
Food preference surveys (taste tests) were performed for 95 food items (which were selected from an original list of 150 items), and 21 menus were developed from the survey results. Each menu contains an entree, two side dishes, dessert, and a beverage. Food manufacturing specifications for freeze dried foods, frozen foods, and beverages are examined, and product labeling and packaging requirements are discussed. The nutritional value of the various foods is listed in tabular form, and sample product labels are shown. Cost estimates per serving are also included.

Minerals, though needed in small quantities, are essential to metabolic processes, and deficiencies can seriously threaten health, reproduction and survival. Despite this, few studies have measured mineral composition of wild primate foods and fewer have quantified mineral intake. Here we measured the concentration of nine minerals in 75 foods of diademed sifakas (Propithecus diadema; five groups) in habitats with varying levels of disturbance at Tsinjoarivo and estimated daily intakes using focal-animal feeding data and intake rates over one year. For six minerals (Ca, P, Na, Fe, Zn, and Cu), mean concentrations in foods fell short of the National Research Council's (NRC) recommendations for captive primates. Concentrations were highest in lianas, herbs, and epiphytes, and hemiparasites had exceptionally high Na. Leaves tended to have higher concentrations than fruits or flowers, but overlap was extensive. Mineral concentrations in daily diets varied little seasonally, but absolute intakes (g/day) were higher in the abundant season, due to the increase in food ingested. Disturbed habitat groups' diets had higher mineral concentrations for five minerals, but this translated into increased intakes only for Cu, as these groups ate less food overall. Overall, comparisons with percentage-based NRC recommendations suggests deficiencies, but this is contradicted by: (1) the fact that mass-specific intakes exceeded human recommendations, and (2) the lack of observed signs of deficiency. Ongoing efforts to quantify mineral consumption across wild primate populations and better understanding requirements on both a percentage and absolute basis will help in understanding effects on food selection, managing primate habitats and formulating captive diets. © 2017 Wiley Periodicals, Inc.

Full Text Available Animal nutrition has been severely challenged by the ban on antimicrobials as growth promoters. This has fostered the study of alternative methods to avoid colonisation by pathogenic bacteria as well as to improve the growth of animals and feed conversion efficiency. These new options should not alter the normal intestinal microbiota, or affect it as little as possible. The use of probiotics, which are live microorganisms that beneficially affect the host by improving its intestinal microbial balance, can be seen as a promising way to achieve that goal. In this study, New Zealand White rabbits were fed diets containing an autochthonous probiotic of Enterococcus spp., with the strains EaI, EfaI and EfaD, and Escherichia coli, with the strains ECI 1, ECI 2 and ECD, during a 25-d trial, to evaluate the impact of the probiotic on the faecal microbiota, including population dynamics and antimicrobial resistance profiles. A control group of rabbits, which was fed a diet containing a commonly used mixture of antimicrobials (colistin, oxytetracycline, and valnemulin, was also studied. To assess the colonisation ability of the mentioned probiotic, the faecal microbiota of the rabbits was characterised up to 10 d after the administration had ended. Isolates of enterococci and E. coli were studied for phylogenetic relationships using enterobacterial repetitive intergenic consensus (ERIC-PCR and pulse-field gel electrophoresis (PFGE, respectively. Although partially affected by an unexpected clinical impairment suffered by the rabbits in the experimental group, our results showed the following. The difference between the growth rate of the animals treated with antimicrobials and those fed the probiotic was not statistically significant (P> 0.05. The competitive exclusion product was present in the faecal samples in a large proportion, but stopped being recovered by culture as soon as the administration ended and the housing conditions were changed

Rapid assessment of the nutritional quality of diets ingested by grazing animals is pivotal for successful cow-calf management in east Mediterranean rangelands, which receive unpredictable rainfall and are subject to hot-spells. Clipped vegetation samples are seldom representative of diets consumed, as cows locate and graze selectively. In contrast, faeces are easily sampled and their near-IR spectra contain information about nutrients and their utilization. However, a pre-requisite for successful faecal near-infrared reflectance spectroscopy (FNIRS) is that the calibration database encompass the spectral variability of samples to be analyzed. Using confined beef cows in Northern and Southern Israel, we calibrated prediction equations based on individual pairs of known dietary attributes and the NIR spectra of associated faeces (n=125). Diets were composed of fresh-cut green fodder of monocots (wheat and barley), dicots (safflower and garden pea) and natural pasture collected at various phenological states over 2 consecutive years, and, optionally, supplements of barley grain and dried poultry litter. A total of 48 additional pairs of faeces and diets sourced from cows fed six complete mixed rations covering a wide range of energy and CP concentrations. Precision (linearity of calibration, R2cal, and of cross-validation, R2cv) and accuracy (standard error of cross-validation, SEcv) were criteria for calibration quality. The calibrations for dietary ash, CP, NDF and in vitro dry matter digestibility yielded R2cal values >0.87, R2cv of 0.81 to 0.89 and SEcv values of 16, 13, 39 and 31 g/kg dry matter, respectively. Equations for nutrient intake were of low quality, with the exception of CP. Evaluation of FNIRS predictions was carried out with grazing animals supplemented or not with poultry litter, and implementation of the method in one herd over 2 years is presented. The potential usefulness of equations was also established by calculating the Mahalanobis (H

As people age they become increasingly susceptible to chronic and extremely debilitating brain diseases. The precise cause of the neuronal degeneration underlying these disorders, and indeed normal brain ageing remains however elusive. Considering the limits of existing preventive methods, there is a desire to develop effective and safe strategies. Growing preclinical and clinical research in healthy individuals or at the early stage of cognitive decline has demonstrated the beneficial impact of nutrition on cognitive functions. The present review is the most recent in a series produced by the Nutrition and Mental Performance Task Force under the auspice of the International Life Sciences Institute Europe (ILSI Europe). The latest scientific advances specific to how dietary nutrients and non-nutrient may affect cognitive ageing are presented. Furthermore, several key points related to mechanisms contributing to brain ageing, pathological conditions affecting brain function, and brain biomarkers are also discussed. Overall, findings are inconsistent and fragmented and more research is warranted to determine the underlying mechanisms and to establish dose-response relationships for optimal brain maintenance in different population subgroups. Such approaches are likely to provide the necessary evidence to develop research portfolios that will inform about new dietary recommendations on how to prevent cognitive decline.

Growth and nutritional intake of children with cows' milk allergy and other food allergens has been thoroughly investigated in recent years across many different countries and age groups. An impaired growth in atopic children should not be attributed only to a high number of allergens and foods to be avoided, but to a general condition of 'sub-inflammation', which unfavorably affects the absorption and utilization of fuel and substrates. Atopic study participants may represent a good target for personalized nutrition and in this review we sought to outline many of the issues that should be taken into account when dietitians advise patients regarding food avoidance and expected effects on growth. The dietary management of food allergy requires appropriate dietary choices to maintain adequate growth, starting with special formulas in infancy. An emerging area of research is the fussy eating related to the exclusion of cow's milk and other foods during infancy and the long-term effects on eating habits and food preferences. Study participants with either mono or polyallergic diseases should ideally undergo the definition of their allergic and metabolic characteristics, to precisely adjust dietary interventions on an individual basis to support the genetic potential of growth and prevent unfavorable outcomes.

Alzheimer's disease (AD) rates in Japan and developing countries have risen rapidly in recent years. Researchers have associated factors such as the Western diet, obesity, alcohol consumption, and smoking with risk of AD. This paper evaluates whether the dietary transition might explain the rising trend of AD prevalence in Japan and in developing countries, evaluating other factors when possible. This study used two approaches to see whether dietary or other changes could explain AD trends in Japan and developing countries. One approach involved comparing trends of AD in Japan with changes in national dietary supply factors, alcohol consumption, and lung cancer mortality rates from zero to 25 years before the prevalence data. The second compared AD prevalence values for eight developing countries with dietary supply factors from zero to 25 years before the prevalence data. For Japan, alcohol consumption, animal product, meat and rice supply, and lung cancer rates correlated highly with AD prevalence data, with the strongest correlation for a lag of 15-25 years. In the eight-country study, total energy and animal fat correlated highly with AD prevalence data, with a lag of 15-20 years. Mechanisms to explain the findings include increased obesity for the eight countries, and increases in cholesterol, saturated fat, and iron from increases in animal products and meat supply for Japan. Evidently AD rates will continue rising in non-Western countries for some time unless we address major risk factors involving diet, obesity, and smoking.

With the increasing popularity of rabbits as household pets, the complexity of diagnostic and surgical procedures performed on rabbits is increasing, along with the frequency of routine surgical procedures. More practitioners are faced with the need to provide adequate analgesia for this species. Preemptive analgesia prior to planned surgical interventions may reduce nervous system changes in response to noxious input, as well as reduce postoperative pain levels and analgesic drug requirements. Concurrent administration of analgesic drugs to anesthetized rabbits undergoing painful procedures is warranted both pre- and intraoperatively as well as postoperatively. This article discusses the neuropharmacologic and pharmacologic aspects of pain in rabbits, and reviews current protocols for the use of analgesic drugs. Published by Elsevier Inc.
Full Text Available This study examined the association between nutritional awareness and diet quality, as indicated by energy density, dietary diversity and adequacy to achieve dietary recommendations, while considering the potentially important role of socioeconomic status (SES. Data were derived from 1351 subjects, aged 18–69 years and enrolled in the ORISCAV-LUX study. Energy density score (EDS, dietary diversity score (DDS and Recommendation Compliance Index (RCI were calculated based on data derived from a food frequency questionnaire. Nutritional awareness was defined as self-perception of the importance assigned to eating balanced meals, and classified as high, moderate, or of little importance. Initially, a General Linear Model was fit that adjusted for age, sex, country of birth, and body mass index (BMI. Furthermore, simultaneous contributions to diet quality of individual-level socioeconomic factors, education, and household income were examined across levels of nutritional awareness. Attributing high importance was associated inversely with energy density (p = 0.02, positively with both dietary diversity (p < 0.0001, and adequacy to dietary recommendations (p < 0.0001, independent of demographic factors, weight status and SES. Further adjustment for household income in the EDS-related multivariable model, reduced the β coefficient by 47% for the “moderate importance” category and 36% for the “high importance” category. Likewise, the β coefficient decreased by 13.6% and 10.7% in the DDS-related model, and by 12.5%, and 7.1% in the RCI-related model, respectively, across awareness categories. Nutritional awareness has a direct effect on diet quality, with a minor component of variance explained by improved income. The impact of nutritional awareness on diet quality seems to be a promising area for both health promotion and health policy research.

To determine whether an experiential nutrition education intervention focusing on spices and herbs ("Spice MyPlate") is feasible and improves diet quality and healthy eating attitudes among an urban and predominantly African-American sample of adolescents more than standard nutrition education alone. A nonrandomized controlled trial compared standard nutrition education in U.S. Department of Agriculture MyPlate guidelines (control group) with standard nutrition education plus adjuvant Spice MyPlate curriculum (intervention group). Data were collected at baseline and after 3, 6, and 10 weeks. Study setting was two public high schools in Baltimore, Maryland. A total of 110 students in grades 9 to 12 participated. The 6-week school-based intervention conducted during health class focused on cooking using spices and herbs to eat healthier diets according to MyPlate. Dietary intake reported on 3-day food records and healthy eating attitudes questionnaires was analyzed. Differences in diet quality and healthy eating attitudes between study groups were estimated by t-tests, Wilcoxon-Mann-Whitney tests, and covariate-adjusted regression models. Spice MyPlate was feasible and there were modest but significant improvements (p ≤ .05) in the Spice MyPlate group compared with control in whole grains (31.2 g/wk) and protein foods (13.2 ounces per week) intake, and attitudes toward eating vegetables, whole grains, lean protein, and low-fat dairy. Although randomized trials are needed, experiential nutrition education focusing on spices and herbs may help urban and predominantly African-American adolescent populations eat healthier diets. © The Author(s) 2016.

We describe the implementation of a 3-week dietary intervention in elite race walkers at the Australian Institute of Sport, with a focus on the resources and strategies needed to accomplish a complex study of this scale. Interventions involved: traditional guidelines of high carbohydrate (CHO) availability for all training sessions (HCHO); a periodized CHO diet which integrated sessions with low CHO and high CHO availability within the same total CHO intake, and a ketogenic low-CHO high-fat diet (LCHF). 7-day menus and recipes were constructed for a communal eating setting to meet nutritional goals as well as individualized food preferences and special needs. Menus also included nutrition support pre, during and post-exercise. Daily monitoring, via observation and food checklists, showed that energy and macronutrient targets were achieved: diets were matched for energy (~14.8 MJ/d) and protein (~2.1 g.kg/d), and achieved desired differences for fat and CHO: HCHO and PCHO: CHO = 8.5 g/kg/d, 60% energy; fat = 20% of energy; LCHF: 0.5 g/kg/d CHO, fat = 78% energy. There were no differences in micronutrient intakes or density between HCHO and PCHO diets; however, the micronutrient density of LCHF was significantly lower. Daily food costs per athlete were similar for each diet (~AUDS$27 ± 10). Successful implementation and monitoring of dietary interventions in sports nutrition research of the scale of the present study require meticulous planning and the expertise of chefs and sports dietitians. Different approaches to sports nutrition support raise practical challenges around cost, micronutrient density, accommodation of special needs and sustainability.
Full Text Available The winter diet of barren-ground caribou may affect adult survival, timing of parturition, neonatal survival, and postpartum mass. We used microhistological analyses and hormone levels in feces to determine sex-specific late-winter diets, pregnancy rates, group composition, and endocrine-based measures of physiological and nutritional stress. Lichens, which are highly digestible but contain little protein, dominated the diet (> 68% but were less prevalent in the diets of pregnant females as compared to non-pregnant females and males. The amount of lichens in the diets of pregnant females decreased at higher latitudes and as winter progressed. Pregnancy rates (82.1%, 95% CI = 76.0 - 88.1% of adult cows were within the expected range for a declining herd, while pregnancy status was not associated with lichen abundance in the diet. Most groups (80% were of mixed sex. Male: female ratios (62:100 were not skewed enough to affect the decline. Levels of hormones indicating nutritional stress were detected in areas of low habitat quality and at higher latitudes. Levels of hormones indicated that physiological stress was greatest for pregnant cows, which faced the increasing demands of gestation in late winter. These fecal-based measures of diet and stress provided contextual information for the potential mechanisms of the ongoing decline. Non-invasive techniques, such as monitoring diets, pregnancy rates, sex ratios and stress levels from fecal samples, will become increasingly important as monitoring tools as the industrial footprint continues to expand in the Arctic.

To test whether diets achieving recommendations from the UK's Scientific Advisory Committee on Nutrition (SACN) were associated with higher monetary costs in a nationally representative sample of UK adults. A cross-sectional study linking 4 d diet diaries in the National Diet and Nutrition Survey (NDNS) to contemporaneous food price data from a market research firm. The monetary cost of diets was assessed in relation to whether or not they met eight food- and nutrient-based recommendations from SACN. Regression models adjusted for potential confounding factors. The primary outcome measure was individual dietary cost per day and per 2000 kcal (8368 kJ). UK. Adults (n 2045) sampled between 2008 and 2012 in the NDNS. On an isoenergetic basis, diets that met the recommendations for fruit and vegetables, oily fish, non-milk extrinsic sugars, fat, saturated fat and salt were estimated to be between 3 and 17 % more expensive. Diets meeting the recommendation for red and processed meats were 4 % less expensive, while meeting the recommendation for fibre was cost-neutral. Meeting multiple targets was also associated with higher costs; on average, diets meeting six or more SACN recommendations were estimated to be 29 % more costly than isoenergetic diets that met no recommendations. Food costs may be a population-level barrier limiting the adoption of dietary recommendations in the UK. Future research should focus on identifying systems- and individual-level strategies to enable consumers achieve dietary recommendations without increasing food costs. Such strategies may improve the uptake of healthy eating in the population.

Results from studies evaluating the sustainability of diets combining environmental and nutritional aspects have been diverse; thus, greenhouse gas emissions (that is, carbon footprint (CF)) of diets in line with dietary recommendations in free-living individuals warrants further examination. Here, changes in dietary CF related to changes in food choice during a weight loss trial among lactating women who received a 12-week diet intervention based on the Nordic Nutrition Recommendations (NNR) 2004 were analyzed. The objective of this study was to examine if a diet intervention based on NNR 2004 results in reduced dietary CF. Changes in dietary CF were analyzed among 61 lactating women participating in a weight loss trial. Food intake data from 4-day weighed diet records and results from life cycle analyses were used to examine changes in dietary CF across eight food groups during the intervention, specified in the unit carbon dioxide equivalent (CO 2 eq/day). Differences in changes in dietary CF between women receiving diet treatment (D-group) and women not receiving it (ND-group) were compared. There was no difference in change in dietary CF of the overall diet between D- and ND-group (P>0.05). As for the eight food groups, D-group increased their dietary CF from fruit and vegetables (+0.06±0.13 kg CO 2 eq/day) compared with a decrease in ND-group (-0.01±0.01 kg CO 2 eq/day) during the intervention, P=0.01. A diet intervention in line with NNR 2004 produced clinically relevant weight loss, but did not reduce dietary CF among lactating women with overweight and obesity. Dietary interventions especially designed to decrease dietary CF and their coherence with dietary recommendations need further exploration.

Brazilian cuisine is much admired by present-day international chefs. However, in the nineteenth century, local ingredients and recipes were looked down upon by the Portuguese colonists, as well as by visiting European naturalists. This fact, together with medical and chemical views formulated throughout the 1800s, led locally trained doctors to attribute the occurrence of countless diseases that devastated Rio de Janeiro to local staple foods, particularly corn and manioc flour. In the first part of the present article, I review the dietary habits of Brazilians through the eyes of European naturalists who travelled across the country in the early nineteenth century. In the second part, I summarise the ideas formulated by French and German chemists on the components, and consequent nutritional value, of cereals and other sources of flour, and then analyse the appropriation of such ideas--particularly those of Justus Liebig--by Brazilian doctors and their adaptation to local conditions.

Nutrition in children has an important influence on health both in childhood and adulthood. Actions aimed at improving children's nutrition are essential, not only to the children and their families, but also to the whole society. The aim of the study was to present the results of nutrient intake before starting a nutrition and physical activity intervention programme, to investigate gender differences in nutrient intake and to discuss whether the preschoolers' nutrient intake is similar to the intake of their peers from other countries. Nutrient intake was estimated from seven-day weighed food records kept by parents and preschool staff individually for 122 4-6-year-old children who attended two preschools in Piła, north-western Poland. Nutrient intake was calculated using Dieta 4.0 computer programme including water intake and intake of nutrients from dietary supplements. Statistical analysis was performed using the IBM SPSS Statistics computer programme, version 21.0, according to gender. The study was approved by the Bioethics Committee of the Poznan University of Medical Sciences (reference number 886/08). Boys, in comparison to girls, were found to have statistically significantly higher intakes of total protein, total protein per kg of body weight, saturated fatty acids, total carbohydrates, available carbohydrates, lactose, sucrose, total water, vitamin A, beta-carotene, vitamin B 2 , vitamin B 12 , vitamin C, calcium, phosphorus, and magnesium. Statistically significantly higher percentage of girls than boys had intakes of vitamin E below AI. Gender was a significant factor of nutrient intake in the studied preschool children. The main nutritional concerns in the studied preschoolers' diets, irrespective of gender, are typical of the diets of preschool children from various parts of Europe and indicate the need to work out common nutritional strategies to improve preschoolers' nutrition across Europe to reduce future burden of diet-related diseases to the

Recent population dietary studies indicate that diets rich in ultra-processed foods, increasingly frequent worldwide, are grossly nutritionally unbalanced, suggesting that the dietary contribution of these foods largely determines the overall nutritional quality of contemporaneous diets. Yet, these studies have focused on individual nutrients (one at a time) rather than the overall nutritional quality of the diets. Here we investigate the relationship between the energy contribution of ultra-processed foods in the US diet and its content of critical nutrients, individually and overall. We evaluated dietary intakes of 9,317 participants from 2009 to 2010 NHANES aged 1+ years. Food items were classified into unprocessed or minimally processed foods, processed culinary ingredients, processed foods, and ultra-processed foods. First, we examined the average dietary content of macronutrients, micronutrients, and fiber across quintiles of the energy contribution of ultra-processed foods. Then, we used Principal Component Analysis (PCA) to identify a nutrient-balanced dietary pattern to enable the assessment of the overall nutritional quality of the diet. Linear regression was used to explore the association between the dietary share of ultra-processed foods and the balanced-pattern PCA factor score. The scores were thereafter categorized into tertiles, and their distribution was examined across ultra-processed food quintiles. All models incorporated survey sample weights and were adjusted for age, sex, race/ethnicity, family income, and educational attainment. The average content of protein, fiber, vitamins A, C, D, and E, zinc, potassium, phosphorus, magnesium, and calcium in the US diet decreased significantly across quintiles of the energy contribution of ultra-processed foods, while carbohydrate, added sugar, and saturated fat contents increased. An inverse dose-response association was found between ultra-processed food quintiles and overall dietary quality measured

The declining diversity of agricultural production and food supplies worldwide may have important implications for global diets. The primary objective of this review is to assess the nature and magnitude of the associations of agricultural biodiversity with diet quality and anthropometric outcomes in low- and middle-income countries. A comprehensive review of 5 databases using a priori exclusion criteria and application of a systematic, qualitative analysis to the findings of identified studies revealed that agricultural biodiversity has a small but consistent association with more diverse household- and individual-level diets, although the magnitude of this association varies with the extent of existing diversification of farms. Greater on-farm crop species richness is also associated with small, positive increments in young child linear stature. Agricultural diversification may contribute to diversified diets through both subsistence- and income-generating pathways and may be an important strategy for improving diets and nutrition outcomes in low- and middle-income countries. Six research priorities for future studies of the influence of agricultural biodiversity on nutrition outcomes are identified based on gaps in the research literature. © The Author(s) 2017.

Temporal dietary patterns, the distribution of energy or nutrient intakes observed over a period of time, is an emerging area of dietary patterns research that incorporates time of dietary intake with frequency and amount of intake to determine population clusters that may have similar characteristics or outcomes related to diet quality. We examined whether differences in diet quality were present between clusters of individuals with similar daily temporal dietary patterns. The first-day 24-hour dietary recall data from the cross-sectional National Health and Nutrition Examination Survey, 1999-2004, were used to determine proportional energy intake, time of intake, frequency of intake occasions, and mean diet quality. Data from 9,326 US adults aged 20 to 65 years were included. The mean diet quality, classified by the Healthy Eating Index-2005, of participant clusters with similar temporal dietary patterns derived on the basis of individual proportional energy intake, time of intake, and frequency of intake, were inferentially compared using multiple linear regression that controlled for potential confounders and other covariates (PDiet quality differences were present between US population clusters exhibiting similar daily temporal dietary patterns (Pdiet quality, demonstrating that elements beyond food and nutrient intake, such as time, can be incorporated with dietary patterns to determine links to diet quality that enhance knowledge of the complicated interplay of time and dietary patterns.

Full Text Available Migration of tribal population to urban areas may increase the risk of non-communicable chronic diseases. In this study an attempt was made to explore the risk factors influencing cardio vascular disease, hypertension and Type 2 diabetes among the tribal migrants living in urban areas. A population based cross sectional study was carried out on tribal migrants (n=138 men, n=137 women aged ≥30 years of low economic status, living in an urban slum (Kondapur of Hyderabad, Telangana, India. Blood lipids, glucose, homocysteine, glycated Haemoglobin, blood pressure and nutritional biochemical markers such as serum albumin, serum protein, Vitamin-D and haemoglobin were examined in a subsample of tribal migrants. The prevalence of overweight in men and women was 35.3% and 32.4% while general obesity was 14.3% and 24.3% respectively. In addition, high concentration of total cholesterol, low density lipo proteins (LDL, triglycerides, homocysteine and glycosylated haemoglobin in the study population was also observed. Duration of stay had no significant association with overweight and obesity. Majority of tribal migrants did not meet at least 50% of RDI of micro-nutrients such as iron (80-84%, vitamin A (81-83% and riboflavin (67-84%. Similar finding was observed with food groups such as leafy vegetables (84-91%, milk and milk products. However, the consumption of fat and protein was found to be ≥70% of RDA indicating transition in diet pattern. The present study shows urban life style and diets may predispose to higher incidence of diabetes, hypertension and atherosclerotic cardiovascular disease among tribal migrants living in urban areas.
Full Text Available Switzerland is a multilingual country located between Germany, France and Italy, which differ by dietary habits and related outcomes. We explored differences in food consumption as well as compliance to the Swiss food-based dietary guidelines (FBDG across the German-, French-, and Italian-speaking regions. The 2014–2015 nationwide cross-sectional survey was conducted among a stratified random sample of 2057 adults aged 18 to 75 years. Trained dietitians assessed food consumption via two non-consecutive 24-h dietary recalls using the international validated software GloboDiet®. Recorded foods and beverages were classified into six groups and 31 subgroups relevant for assessing compliance to the FBDG (Swiss Food Pyramid. Usual daily intake distributions were modelled and weighted for sampling design, non-response, weekdays and season. Participation rate was 38%. Significant differences across regions were observed in 18 of 31 food subgroups (p ≤ 0.01. Weighted mean daily intakes in the German-, French- and Italian-speaking regions were, respectively, 245 g, 155 g, 140 g for soft drinks, 273 g, 214 g, 135 g for coffee, 127 g, 72 g, 109 g for milk, 32 g, 45 g, 43 g for red meat, 18 g, 29 g, 34 g for fish/seafood, 8.1 g, 6.4 g, 3.7 g for butter, and 206 g, 214 g, 168 g for vegetables. The seven FBDGs were followed by <1% of the population. Four in 10 participants met ≥3 FBDG. Eighteen percent of participants ate ≥5 portions of fruit and vegetables a day, without regional differences. Food consumption substantially differed across the three linguistic regions of Switzerland. Adherence to FBDG was uniformly low. This highlights the potential influence of culture on diet. Nutritional education along with public health interventions are needed and may be most efficient if regionally targeted.

Entomopathogenic nematodes, Heterorhabditis indica and Steinernema riobrave, were tested for virulence and reproductive yield in Tenebrio molitor that were fed wheat bran diets with varying lipid- and protein-based supplements. Lipid supplements were based on 20% canola oil, peanut, pork or salmon, or a low lipid control (5% canola). Protein treatments consisted of basic supplement ingredients plus 0, 10, or 20% egg white; a bran-only control was also included. Some diet supplements had positive effects on nematode quality, whereas others had negative or neutral effects. All supplements with 20% lipids except canola oil caused increased T. molitor susceptibility to H. indica, whereas susceptibility to S. riobrave was not affected. Protein supplements did not affect host susceptibility, and neither lipid nor protein diet supplements affected reproductive capacity of either nematode species. Subsequently, we determined the pest control efficacy of progeny of nematodes that had been reared through T. molitor from different diets against Diaprepes abbreviatus and Otiorhynchus sulcatus. All nematode treatments reduced insect survival relative to the control (water only). Nematodes originating from T. molitor diets with the 0% or 20% protein exhibited lower efficacy versus D. abbreviatus than the intermediate level of protein (10%) or bran-only treatments. Nematodes originating from T. molitor lipid or control diets did not differ in virulence. Our research indicates that nutritional content of an insect host diet can affect host susceptibility to entomopathogenic nematodes and nematode fitness; therefore, host media could conceivably be optimized to increase in vivo nematode production efficiency.

The use of innovative technologies is deemed to improve dietary assessment in various research settings. However, their relative merits in nutritional epidemiological studies, which require accurate quantitative estimates of the usual intake at individual level, still need to be evaluated. To report on the inventory of available innovative technologies for dietary assessment and to critically evaluate their strengths and weaknesses as compared with the conventional methodologies (i.e. Food Frequency Questionnaires, food records, 24-hour dietary recalls) used in epidemiological studies. A list of currently available technologies was identified from English-language journals, using PubMed and Web of Science. The search criteria were principally based on the date of publication (between 1995 and 2011) and pre-defined search keywords. Six main groups of innovative technologies were identified ('Personal Digital Assistant-', 'Mobile-phone-', 'Interactive computer-', 'Web-', 'Camera- and tape-recorder-' and 'Scan- and sensor-based' technologies). Compared with the conventional food records, Personal Digital Assistant and mobile phone devices seem to improve the recording through the possibility for 'real-time' recording at eating events, but their validity to estimate individual dietary intakes was low to moderate. In 24-hour dietary recalls, there is still limited knowledge regarding the accuracy of fully automated approaches; and methodological problems, such as the inaccuracy in self-reported portion sizes might be more critical than in interview-based applications. In contrast, measurement errors in innovative web-based and in conventional paper-based Food Frequency Questionnaires are most likely similar, suggesting that the underlying methodology is unchanged by the technology. Most of the new technologies in dietary assessment were seen to have overlapping methodological features with the conventional methods predominantly used for nutritional epidemiology. Their

Food processing alters food from its natural state for safety, convenience, taste or palatability. Previous research suggests that industrially processed foods, and diets high in these products, tend to be less healthful. However, most previous work is based on household, rather than individual-level, data. Little has been reported on the relationship between processed food consumption and markers of health; or on socio-demographic correlates of processed food consumption. Our objective was to describe: the nutritional content of foods classified according to degree of processing; the nutritional content of diets with different relative intakes of processed foods; the socio-demographic characteristics of individuals with different relative intakes of processed foods; and the association between intake of processed foods and body weight. Secondary analysis of data from the UK National Diet and Nutrition Survey (2008-12), a large national cross-sectional study of diet. Dietary information was collected using four-day, unweighed, food-diaries. Foods were classified as: unprocessed or minimally processed (MPF; foods with no processing or mostly physical processes applied to single whole foods), processed ingredients (PI; extracted and purified components of single whole foods), or ultra-processed food products (UPF; products produced from industrial combining of MPF and PI). Two thousand one hundred seventy four adults were included. MPF and diets high in these foods, had the most healthful nutritional profile. UPF did not necessarily have the least healthful nutritional profile, but diets high in these foods did. Women, and older adults consumed more energy from MPF, and less from UPF. Those living in lower occupation social class households consumed less energy from MPF, but no more from UPF. Only higher intake of PI was consistently, inversely, associated with body weight. This is the first study to explore correlates of processed food consumption, using individual

Full Text Available Stereotype is a term designated to some generalized perceptions that people attri-bute to another individual, groups, objects and/or events. Objective: The purpose of this study was to evaluate the priorities that nutritionist and triathletes attributed to food to enhance the sport performance. Method: The sample was composed by 56 subjects, splited in two groups: Nutritionists (G1, n = 29 and Triathletes (G2, n = 27. The Intake Food Priority Question-naire (QPA, composed by food groups, was used to evaluate the importance of each food in the athletic performance. Results: To the data analysis, each food was grouped into one of the eight categories designed in nutrition pyramid. An arithmetic means were elaborated to categories and it was performed t tests for independent samples to compare nutritionists and triathletes priorities about each category. There were no differences between groups in Vegetables, Leguminous, Fruits and Sugar/Candies categories and, also, to the black coffee item. However, the triathletes overestimated the Cereals/Breads/Tubercle and Meat/Eggs categories and underestimated the Milk/Dairy Products and Oils/Fat categories. Conclusion: The triathletes overestimated some macronutrients (carbohydrates and proteins in detriment from another, like lipids.

To assess dietary intake of customers from out-home eating, and evaluate their energy and main nutrition closely related with chronic disease consumption in one dinner. On dinner time (lunch or supper), 2204 customers randomly selected in six middle-level table-service restaurants in Beijing, were investigated their food consumption by single-blind recording their ordered dishes weight before and after eating. According to the dish recipes, cooking way, and food composition database or measured data, food consumption and energy, protein, fat and sodium intake were evaluated. The mean intake of foods for a standardized man per dinner included 76 g cereals, 162 g vegetables, 11 g fruits, 128g meat, 50g fishery products, 10g eggs, 12 g legumes, 15 g pure energy food, 28 g oil, 7 g salt, 68. 1 g juice, and 7. 3 g alcohol, with 4648 kJ energy, 54. 6 g protein, 62. 3 g fat, 88. 0 g carbohydrate, 10. 7 g cholesterol and 2920 mg sodium. The percentage for energy suppliers were respectively protein 20. 7%, fat 52. 7%, carbohydrate 29. 4%. Contrast to 4180 kJ/1000 kcal energy intake, the food density for oil and salt was 2 times, and meat 3 times over that suggested by Chinese Dietary Pagoda. Out-home eating per dinner supplies nearly daily-need fat and sodium, that partially contributes to high intake of animal foods.

Full Text Available Five Holstein cows were distributed in a 5x5 latin square design to assess the effect of replacement levels of dry ground corn grain (DGCG by high moisture corn silage (HMCS on intake, total nutrient digestibility and plasma glucose, according to the following treatments: 1 100% DGCG; 2 75% DGCG and 25% HMCS; 3 50% DGCG and 50% HMCS; 4 25% DGCG and 75% HMCS; 5 100% HMCS. The experiment lasted 70 days, divided into five phases of 14 days each. The digestibility was obtained using chromic oxide (Cr2O3 as the indicator. Fecal samples were collected twice daily and blood samples were collected on the last day of each period before the first meal (0h and 2h, 4h, 6h and 12h after the meal. There was no effect (P>0.05 on the intake of dry matter (DM, neutral detergent fiber (NDF, acid detergent fiber (ADF and starch. The total apparent digestibility of DM, crude protein (CP, NDF and ADF were not affected (P>0.05 by the treatments, as well as the plasma glucose concentration. However, there was a decreased linear effect (P<0.05 for the protein intake and increased linear effect (P<0.05 for starch digestibility, as the level of HMCS was increased in the diets.

Fibromyalgia is a chronic rheumatic disease producing widespread pain, associated to a major comorbidity -irritable bowel syndrome. Low FODMAPS diet (low fermentable oligo-di-mono-saccharides and polyols diet) has been effective in controlling irritable bowel syndrome symptoms. Overweight is an aggravating factor for fibromyalgia. We studied effects of low fermentable oligo-di-mono-saccharides and polyols diets on fibromyalgia symptoms and weight status. A longitudinal study was performed on 38 fibromyalgia patients using a four-week, repeated assessment as follow: M1 = first assessments/presentation of individual low fermentable oligo-di-mono-saccharides and polyols diet; M2 = second assessments/reintroduction of FODMAPs; M3 = final assessments/nutritional counselling. The assessment instruments applied were: Fibromyalgia Survey Questionnaire (FSQ); Severity Score System (IBS-SSS); visual analogic scale (VAS). Body mass-index/composition and waist circumference (WC) were also measured. Daily macro-micronutrients and FODMAP intake were quantified at each moment of the study. The studied cohort was 37% overweight, 34% obese (average body mass-index 27.4 ± 4.6; excess fat mass 39.4 ± 7%). Weight, body mass-index and waist circumference decreased significantly (p body composition was observed. All fibromyalgiasymptoms, including somatic pain, declined significantly post-LFD (p fibromyalgia [Fibromyalgia survey questionnaire: M1 = 21.8; M2 = 16.9; M3 = 17.0 (p < 0.01)]. The intake of essential nutrients (fiber, calcium, magnesium and vitamin D) showed no significant difference. The significant reduction in FODMAP intake (M1 = 24.4 g; M2 = 2.6g; p < 0.01) reflected the "Diet adherence" (85%). "Satisfaction with improvement of symptoms" (76%), showed correlating with "diet adherence" (r = 0.65; p < 0.01). Results are highly encouraging, showing low fermentable oligo-di-mono-saccharides and polyols diets as a nutritionally balanced approach, contributing to weight loss
Full Text Available Unfavourable conditions throughout the period of parental care can severely affect growth, reproductive performance, and survival. Yet, individuals may be affected differently, depending on the developmental period during which constraints are experienced. Here we tested whether the nestling phase compared to the fledgling phase is more susceptible to nutritional stress by considering biometry, physiology, sexually selected male ornaments and survival using zebra finches (Taeniopygia guttata as a model species. As nestlings (day 0-17 or fledglings (day 17-35, subjects were raised either on low or high quality food. A low quality diet resulted in significantly elevated baseline corticosterone titres in both nestlings and fledglings. Subjects showed substantial compensatory growth after they had experienced low quality food as nestlings but catch-up growth did neither lead to elevated baseline corticosterone titres nor did we detect long term effects on biometry, male cheek patch, or survival. The compensation for temporally unfavourable environmental conditions reflects substantial phenotypic plasticity and the results show that costs of catch-up growth were not mediated via corticosterone as a physiological correlate of allostatic load. These findings provide new insights into the mechanisms and plasticity with which animals respond to periods of constraints during development as they may occur in a mistiming of breeding.

The objective of the study is to evaluate the nutritional quality of meals consumed away from home and its association with overall diet quality. Data was obtained from 834 participants of a Health Survey in São Paulo, Brazil. Food intake was measured by a 24-hour dietary recall applied telephonically using the Automated Multiple-Pass Method. Overall dietary quality was assessed by the Brazilian Healthy Eating Index Revised (B-HEIR) and the Meal Quality Index (MQI) was used to evaluate dietary quality of the main meals. The association between the B-HEIR and the MQI was assessed by linear regression analysis. The consumption of at least one of the three main meals away from home was reported for 32% of respondents (70 adolescents, 156 adults and 40 elderly). The average MQI score of lunch consumed away from home was lower than lunch consumed at home, with higher amounts of total and saturated fats. The average score of B-HEIR was 58 points and was associated with the MQI score, energy, meal consumption location and gender. Lunch consumed away from home presented the worst quality, being higher in total and saturated fat. However, the meals consumed at home also need improvement. Copyright © 2013 Elsevier Inc.

Full Text Available The aim of this study was to establish relationships between chemical and physical parameters of wheat with performance and digestibilities of feed components in broiler chickens fed on wheat-based diets. Ninety-four wheat samples were selected for inclusion in four bird trials. Birds were housed in individual wire metabolism cages from 7 to 28 d and offered water and feed ad libitum. Dry matter intake (DMI, liveweight gain (LWG and gain:feed were measured weekly. A balance collection was carried out from 14 to 21 d for determination of apparent metabolizable energy (AME, ME:gain, dry matter retention, oil and neutral detergent fibre (NDF digestibility. At 28 d the birds were humanely killed, the contents of the jejunum removed for determination of in vivo viscosity and the contents of the ileum removed for determination of ileal dry matter, starch and protein digestibility. When wheat parameters were correlated with bird performance data, it was found that specific weight was not significantly (p>0.05 related to bird performance. Bird DMI, LWG and gain:feed were best correlated (p<0.05 with the rate of starch digestion, although the coefficients of correlation (r were still low (0.246 to 0.523. A negative relationship (p<0.01 between AME and total (r = −0.432 and soluble (r = −0.304 non starch polysaccharide (NSP was observed in this study. Thousand grain weight (TG was positively correlated with DMI (r = 0.299, LWG (r = 0.343 and gain:feed (r = 0.371. When establishing multiple regression relationships, correlation coefficients greater than 0.8 were achieved for DMI, LWG, gain:feed and ileal crude protein digestibility. However, the economics involved in determining the parameters involved in the regressions make the process impractical.

Consumption of carbohydrate-containing foods leads to transient postprandial rises in blood glucose concentrations that vary between food types. Higher postprandial glycaemic exposures have particularly been implicated in the development of chronic cardiometabolic diseases. Reducing such diet-related exposures may be beneficial not only for diabetic patients but also for the general population. A variety of markers have been used to track different aspects of glycaemic exposures, with most of the relevant knowledge derived from diabetic patients. The assessment of glycaemic exposures among the non-diabetic population may require other, more sensitive markers. The present report summarises key messages of presentations and related discussions from a workshop organised by Unilever intended to consider currently applied markers of glycaemic exposure. The particular focus of the meeting was to identify the potential applicability of glycaemic exposure markers for studying dietary effects in the non-diabetic population. Workshop participants concluded that markers of glycaemic exposures are sparsely used in intervention studies among non-diabetic populations. Continuous glucose monitoring remains the optimal approach to directly assess glycaemic exposure. Markers of glycaemic exposure such as glycated Hb, fructosamine, glycated albumin, 1,5-anhydroglucitol and advanced glycation end products can be preferred dependent on the aspect of interest (period of exposure and glucose variability). For all the markers of glycaemia, the responsiveness to interventions will probably be smaller among the non-diabetic than among the diabetic population. Further validation and acceptance of existing glycaemic exposure markers applied among the non-diabetic population would aid food innovation and better design of dietary interventions targeting glycaemic exposure.
Working toward Healthy and Sustainable Diets: The “Double Pyramid Model” Developed by the Barilla Center for Food and Nutrition to Raise Awareness about the Environmental and Nutritional Impact of Foods

The Barilla Center for Food and Nutrition has produced an updated version of the traditional food pyramid based on the Mediterranean diet in order to assess the simultaneous impact that food has on human health and the environment. The Double Pyramid Model demonstrates how the foods recommended to be consumed most frequently are also those exerting less environmental impact, whereas the foods that should be consumed less frequently are those characterized by a higher environmental impact. The environmental impacts resulting from three different menus were compared. All menus were equally balanced and comparable in terms of nutrition, but they differed in relation to the presence of absence of animal flesh and animal products. The first dietary pattern (omnivorous) included both animal flesh and products; the second (lacto-ovo-vegetarian) included animal products (eggs and dairy) but no flesh; and the third (vegan) was solely plant-based. The results obtained suggest that a diet based on the principles of the Mediterranean diet, as suggested by the Double Pyramid, generates a lower environmental impact compared to diets that are heavily based on daily meat consumption.

Full Text Available Legumes are a rich source of various nutrients. In the Polish culture, one of the varieties of beans has a special significance. Due to the appearance of seeds – on the bright seeds there are dark red spots in the shape of the Piast eagle – at the times of annexation, it was recognised as a symbol of patriotism. Cultivation was therefore banned then by the authority. Today, this bean variety was entered on the list of traditional products in Poland. Bean in Poland is one of the twelve Christmas Eve dishes. Health benefits of legumes have been known since the ancient times in many countries. Anticancer properties are due to the presence of enzymes which affect the division, differentiation, and apoptosis cells in the body. Rich in phytoestrogens, especially isoflavones, they protect women against the development of hormone-dependent cancers and reduce the symptoms associated with menopause. Rich in fibre, they regulate the motility of the gastrointestinal tract and have prebiotic properties. They also reduce insulin resistance in type 2 diabetes. By influencing the expression of genes involved in β-oxidative fats and gluconeogenesis, lipogenesis, they reduce triglyceride levels, LDL cholesterol and increase the levels of HDL cholesterol. Moreover, they help to maintain a normal body weight and reduce high blood pressure. It is therefore recommended particularly for people suffering from the metabolic syndrome or predisposed to its occurrence. It is advised to increase the content of legumes in our diet because of the health benefits and taste.

In order to meet growing public health nutrition challenges in Central Eastern European Countries (CEEC) and Balkan countries, development of a Research Infrastructure (RI) and availability of an effective nutrition surveillance system are a prerequisite. The building block of this RI is an innovative tool called DIET ASSESS & PLAN (DAP), which is a platform for standardized and harmonized food consumption collection, comprehensive dietary intake assessment and nutrition planning. Its unique structure enables application of national food composition databases (FCDBs) from the European food composition exchange platform (28 national FCDBs) developed by EuroFIR (http://www.eurofir.org/) and in addition allows communication with other tools. DAP is used for daily menu and/or long-term diet planning in diverse public sector settings, foods design/reformulation, food labelling, nutrient intake assessment and calculation of the dietary diversity indicator, Minimum Dietary Diversity-Women (MDD-W). As a validated tool in different national and international projects, DAP represents an important RI in public health nutrition epidemiology in the CEEC region. Copyright © 2016 Elsevier Ltd.

A colony of New Zealand white rabbits has been developed which, when fed a cholesterol-supplemented diet, exhibit unusual resistance to hypercholesterolemia and atherosclerosis, disorders usually observed in normal cholesterol-fed rabbits. When resistant rabbits (RT) were fed a normal low cholesterol diet (ND), their plasma lipoprotein patterns were significantly different from those of normal rabbits (NR) fed the same diet. The low density lipoprotein cholesterol (LDL-c)/high density lipoprotein cholesterol (HDL-c) ratio and LDL-c/very low density lipoprotein cholesterol (VLDL-c) ratio were lower in the resistant rabbits. The hydrated density of HDL of the normal-responsive rabbits was greater than that of the resistant rabbits. LDL from resistant rabbits contained a lower proportion of esterified cholesterol and protein than LDL from normal rabbits. Peripheral mononuclear cells from resistant rabbits bound about 30% more 125 I-labeled rabbit LDL than mononuclear cells from normal rabbits. These results demonstrate that the plasma cholesterol levels of these animals is at least partly under genetic control and that compositional differences exist between the major plasma lipoprotein classes of normal and resistant rabbits even during the ingestion of low-cholesterol diet. The results indicate that at least a part of the difference in the cholesterolemic responses between the two rabbit groups is due to an enhanced LDL uptake by the mononuclear cells, and presumably by other somatic cells of the resistant group

Full Text Available In the context of limited marine resources, the exponential growth of aquaculture requires the substitution of fish oil and fishmeal, the traditional components of fish feeds by terrestrial plant ingredients. High levels of such substitution are known to negatively impact fish performance such as growth and survival in rainbow trout (Oncorhynchus mykiss as in other salmonids. In this respect, genetic selection is a key enabler for improving those performances and hence for the further sustainable development of aquaculture. We selected a rainbow trout line over three generations for its ability to survive and grow on a 100% plant-based diet devoid of both fish oil and fishmeal (V diet from the very first meal. In the present study, we compared the control line and the selected line after 3 generations of selection, both fed either the V diet or a marine resources-based diet (M diet. The objective of the study was to assess the efficiency of selection and the consequences on various correlated nutritional traits: feed intake, feed efficiency, digestibility, composition of whole fish, nutrient retention and fatty acid (FA profile. We demonstrated that the genetic variability present in our rainbow trout population can be selected to improve survival and growth. The major result of the study is that after only three generations of selection, selected fish fed the V diet grew at the same rate as the control line fed the M diet, whilst the relative reduction of body weight was 36.8% before the selection. This enhanced performance on the V diet seems to be mostly linked to a higher feed intake for the selected fish.

Monitoring the nutritional status of range cows is difficult. Near-infrared spectroscopy (NIRS) of feces has been used to predict diet quality in cattle. When fecal NIRS is coupled with decision support software such as the Nutritional Balance Analyzer (NUTBAL PRO), nutritional status and animal performance can be monitored. Approximately 120 Hereford and 90 CGC composite (50% Red Angus, 25% Tarentaise, and 25% Charolais) cows grazing in a single herd were used in a study to determine the ability of fecal NIRS and NutbalPro to project BCS (1 = thin and 9 = fat) under commercial scale rangeland conditions in central Arizona. Cattle were rotated across the 31,000 ha allotment at 10 to 20 d intervals. Cattle BCS and fecal samples (approximately 500 g) composited from 5 to 10 cows were collected in the pasture approximately monthly at the midpoint of each grazing period. Samples were frozen and later analyzed by NIRS for prediction of diet crude protein (CP) and digestible organic matter (DOM). Along with fecal NIRS predicted diet quality, animal breed type, reproductive status, and environmental conditions were input to the software for each fecal sampling and BCS date. Three different evaluations were performed. First, fecal NIRS and NutbalPro derived BCS was projected forward from each sampling as if it were a "one-time only" measurement. Second, BCS was derived from the average predicted weight change between 2 sampling dates for a given period. Third, inputs to the model were adjusted to better represent local animals and conditions. Fecal NIRS predicted diet quality varied from a minimum of approximately 5% CP and 57% DOM in winter to a maximum of approximately 11% CP and 60% DOM in summer. Diet quality correlated with observed seasonal changes and precipitation events. In evaluation 1, differences in observed versus projected BCS were not different (P > 0.1) between breed types but these values ranged from 0.1 to 1.1 BCS in Herefords and 0.0 to 0.9 in CGC. In

The aim of this study was to determine the knowledge and attitudes of pet rabbit owners at the time of buying their rabbit(s) and to investigate factors influencing the planned husbandry and housing of their rabbit(s). A questionnaire was used to assess the impact of demographics, knowledge and attitudes on the likelihood that respondents would neuter their rabbit(s), feed them an appropriate diet, house them in appropriately sized housing and provide them with an appropriate companion. Knowledge and attitudes were significant factors in whether respondents planned to neuter their rabbit(s) and provide them with an appropriate companion. The attribution of secondary emotions to rabbits was associated with plans to feed a mix-type diet. The majority of owners had carried out prior research into pet rabbits, but owners had a limited knowledge of the needs of rabbits, particularly with respect to their diet and social needs. Respondents who had decided to purchase a rabbit on the day were less likely to intend to get their rabbit neutered than those who had taken more time to decide to buy a rabbit.

Switzerland is a multilingual country located between Germany, France and Italy, which differ by dietary habits and related outcomes. We explored differences in food consumption as well as compliance to the Swiss food-based dietary guidelines (FBDG) across the German-, French-, and Italian-speaking regions. The 2014-2015 nationwide cross-sectional survey was conducted among a stratified random sample of 2057 adults aged 18 to 75 years. Trained dietitians assessed food consumption via two non-consecutive 24-h dietary recalls using the international validated software GloboDiet ® . Recorded foods and beverages were classified into six groups and 31 subgroups relevant for assessing compliance to the FBDG (Swiss Food Pyramid). Usual daily intake distributions were modelled and weighted for sampling design, non-response, weekdays and season. Participation rate was 38%. Significant differences across regions were observed in 18 of 31 food subgroups ( p ≤ 0.01). Weighted mean daily intakes in the German-, French- and Italian-speaking regions were, respectively, 245 g, 155 g, 140 g for soft drinks, 273 g, 214 g, 135 g for coffee, 127 g, 72 g, 109 g for milk, 32 g, 45 g, 43 g for red meat, 18 g, 29 g, 34 g for fish/seafood, 8.1 g, 6.4 g, 3.7 g for butter, and 206 g, 214 g, 168 g for vegetables. The seven FBDGs were followed by Nutritional education along with public health interventions are needed and may be most efficient if regionally targeted.

Mutually exclusive clusters of individuals were identified using the percentage of energy derived from foods of each of the 5-CNL colours as input variables. Three scenarios of substitution of foods for healthier alternative using the 5-CNL were tested. Food group and dietary intakes, socio-demographic and lifestyle data were compared across clusters using ANOVAs or Chi-square tests, as appropriate. We identified three mutually exclusive dietary profiles: 'Healthy' (N = 28 095, 29.3% of the sample, with high consumption of fruit, vegetables, whole cereals and fish; 'Western' (N = 33 386, 34.8%; with high consumption of sweetened beverages, breakfast cereal, cheese, fatty and sugary foods; 'Traditional' (N = 34 461, 35.1%, with high consumption of potatoes, bread, meat and dairy desserts. Overall, substitutions strategies led to an increase in the number of subjects reaching the recommended intakes in energy, macro and micronutrients. Increases were particularly high in the 'Western' pattern for lipids and saturates intakes: from 16.2% reaching the recommended amount for lipids (13.5% for saturates to 60.6% and 85.7% respectively.The use of the 5-CNL as an indicator of food choice meaningfully characterizes clusters of dietary habits and appears as an effective tool to help improving the nutritional quality of the diet.

Hypercholesterolemia represents a high risk factor for frequent diseases and it has also been associated with poor semen quality that may lead to male infertility. The aim of this study was to analyze semen and sperm function in diet-induced hypercholesterolemic rabbits. Twelve adult White New Zealand male rabbits were fed ad libitum a control diet or a diet supplemented with 0.05% cholesterol. Rabbits under cholesterol-enriched diet significantly increased total cholesterol level in the serum. Semen examination revealed a significant reduction in semen volume and sperm motility in hypercholesterolemic rabbits (HCR). Sperm cell morphology was seriously affected, displaying primarily a “folded head”-head fold along the major axe-, and the presence of cytoplasmic droplet on sperm flagellum. Cholesterol was particularly increased in acrosomal region when detected by filipin probe. The rise in cholesterol concentration in sperm cells was determined quantitatively by Gas chromatographic-mass spectrometric analyses. We also found a reduction of protein tyrosine phosphorylation in sperm incubated under capacitating conditions from HCR. Interestingly, the addition of Protein Kinase A pathway activators -dibutyryl-cyclic AMP and iso-butylmethylxanthine- to the medium restored sperm capacitation. Finally, it was also reported a significant decrease in the percentage of reacted sperm in the presence of progesterone. In conclusion, our data showed that diet-induced hypercholesterolemia adversely affects semen quality and sperm motility, capacitation and acrosomal reaction in rabbits; probably due to an increase in cellular cholesterol content that alters membrane related events.

This paper reviews and evaluates the available data on diet and nutritional status of Amerindians living in the tropical forests of Amazonia. The diets of most Amerindians are based on cassava and plantains/bananas, with high quality protein coming from fish, game and invertebrates. The composition of Amerindian diets is known for only a few groups. In these groups the dietary intake of households and adults appears to be adequate in energy and protein. However, the high bulk, low caloric den...

A colonic separation mechanism (CSM) is the prerequisite for the digestive strategy of coprophagy. Two different CSM are known in small herbivores, the 'wash-back' CSM of lagomorphs and the 'mucous-trap' CSM of rodents. Differences between these groups in their digestive pattern when fed exclusively hay were investigated in six rabbits (Oryctolagus cuniculus) and six guinea pigs (Cavia porcellus). Intake, digestibility (by total faecal collection), solute and particle mean retention times (MRT, using Co-EDTA and Cr-mordanted fibres) were measured. Rabbits selected less fibrous parts of the hay than guinea pigs, leaving orts with higher content of neutral detergent fibre [NDF; 721 ± 21 vs. 642 ± 31 g/kg dry matter (DM) in guinea pigs]. They also expressed a lower NDF digestibility (0.44 ± 0.10 vs. 0.55 ± 0.05 of total), a similar particle MRT (15 ± 3 vs. 18 ± 6 h), a longer solute MRT (51 ± 9 vs. 16 ± 4 h), and a lower calculated dry matter gut fill (19.6 ± 4.7 vs. 29.7 ± 4.1 g DM/kg body mass) than guinea pigs (p bacterial matter from the colonic digesta plug than the 'mucous-trap' CSM found in the guinea pigs. Related to metabolic body mass, rabbits therefore need a less capacious colon for their CSM where a more efficient bacteria wash-out is reflected in the lower fibre digestibility. A lighter digestive tract could contribute to a peculiarity of lagomorphs: their ability to run faster than other similar-sized mammals. © 2010 Blackwell Verlag GmbH.

Clinical inference suggests the prevalence of non-celiac gluten sensitivity is substantially higher than that of celiac disease in the USA. Unfortunately, there are currently no data supporting these claims. The authors analyzed nationally representative data to estimate the prevalence of adherence to a gluten-free diet among participants without celiac disease and also to characterize the demographics and general health status of these participants. The Continuous National Health and Nutrition Examination Survey (NHANES) 2009-2010 enrolled 7762 individuals representing the civilian, non-institutionalized, US population free of celiac disease. Participants responded to interviewer administered questionnaires regarding current adherence to a gluten-free diet. Prevalence estimates were computed using SAS survey procedures. There were 49 individuals who reported current adherence to a gluten-free diet reflecting a weighted prevalence of 0.548% (95% CI 0.206-0.889). The prevalence of a gluten-free diet was higher in females (0.58%) than males (0.37%), although this was not statistically significant (p = 0.34). Participants reporting a gluten-free diet were older (46.6 vs. 40.5 years, p = 0.005), had higher high-density lipoprotein, lower iron and lower body mass index. The estimated national prevalence of non-celiac gluten sensitivity is 0.548%, approximately half that of celiac disease. Future studies are merited in order to better understand the population burden of non-celiac gluten sensitivity.

Diet quality or macronutrient composition of total daily sodium intake (dNa) <2300 mg/day in the United States (US) is unknown. Using data from 2011-2014 NHANES (National Health and Nutrition Examination Survey), we examined 24-h dietary recalls ( n = 10,142) from adults aged ≥18 years and investigated how diet composition and quality are associated with dNa. Diet quality was assessed using components of macronutrients and Healthy Eating Index 2010 (HEI-2010). Associations were tested using linear regression analysis adjusted for total energy (kcal), age, gender, and race/ethnicity. One-day dNa in the lower quartiles were more likely reported among women, older adults (≥65 years old), and lower quartiles of total energy (kcal) ( p -values ≤ 0.001). With increasing dNa, there was an increase in the mean protein, fiber, and total fat densities, while total carbohydrates densities decreased. As dNa increased, meat protein, refined grains, dairy, and total vegetables, greens and beans densities increased; while total fruit and whole fruit densities decreased. Modified HEI-2010 total score (total score without sodium component) increased as dNa increased (adjusted coefficient: 0.11, 95% confidence interval = 0.07, 0.15). Although diet quality, based on modified HEI-2010 total score, increased on days with greater dNa, there is much room for improvement with mean diet quality of about half of the optimal level.

Full Text Available Diet-quality scores (DQS, which are developed across the globe, are used to define adherence to specific eating patterns and have been associated with risk of coronary heart disease and type-II diabetes. We explored the association between five diet-quality scores (Healthy Eating Index, HEI; Alternate Healthy Eating Index, AHEI; MedDietScore, MDS; PREDIMED Mediterranean Diet Score, P-MDS; Dutch Healthy Diet-Index, DHDI and markers of metabolic health (anthropometry, objective physical activity levels (PAL, and dried blood spot total cholesterol (TC, total carotenoids, and omega-3 index in the Food4Me cohort, using regression analysis. Dietary intake was assessed using a validated Food Frequency Questionnaire. Participants (n = 1480 were adults recruited from seven European Union (EU countries. Overall, women had higher HEI and AHEI than men (p < 0.05, and scores varied significantly between countries. For all DQS, higher scores were associated with lower body mass index, lower waist-to-height ratio and waist circumference, and higher total carotenoids and omega-3-index (p trends < 0.05. Higher HEI, AHEI, DHDI, and P-MDS scores were associated with increased daily PAL, moderate and vigorous activity, and reduced sedentary behaviour (p trend < 0.05. We observed no association between DQS and TC. To conclude, higher DQS, which reflect better dietary patterns, were associated with markers of better nutritional status and metabolic health.

Low adherence is frequently observed in patients with chronic kidney disease (CKD) who are following a low-protein diet. We have evaluated whether a specific nutrition education program motivates patients with CKD who do not yet receive dialysis to reduce their protein intake and whether such a program improves adherence to a low-protein diet over and above standard dietary counseling. This was a randomized controlled clinical trial conducted at the CKD outpatient clinic at Pedro Ernesto University Hospital, Rio de Janeiro, Brazil. This study included adult patients with an estimated glomerular filtration rate (eGFR) Patients were randomized to a normal counseling group (individualized dietary program: 0.6 to 0.75 g protein/kg/day or 0.6 to 0.8 g/kg/day for patients with diabetes and 25 to 35 kcal/kg/day with sodium restriction) or an intense counseling group (same dietary program plus nutrition education materials). The nutrition education material included 4 different actions to improve patient knowledge and understanding of the low-protein and low-sodium diet. Both groups were followed by means of individual monthly visits to the outpatient clinic for 4 months. We looked for a change in protein intake from baseline values as well as the adherence rate, assessed as a 20% decrease of the initial protein intake (by 24-hour food recall). Eighty-nine patients completed the study (normal counseling n = 46; intense counseling n = 43). The number of patients who adhered to a low-protein diet was high but did not differ between groups (in the last visit 69% vs. 48%; P = .48; intense vs. normal counseling, respectively). The reduction in protein intake from baseline values was greater for the intense counseling group compared with the normal counseling group (at the last visit, -20.7 g/day [-30.9%] vs. -10.5 g/day [-15.1%], intense vs. normal counseling, respectively; P = .04). An intense nutrition education program contributed to reducing protein intake in patients with

The associations between eating frequency and diet quality are inconclusive, which might be a result of different effects of meal frequency and snack frequency. This cross-sectional study examined the associations of eating frequency, meal frequency, and snack frequency with diet quality, based on data from the National Health and Nutrition Examination Survey 2003-2012. Dietary intake was assessed in 19,427 US adults aged 20 years or older, using two 24-hour dietary recalls. All eating occasions providing ≥50 kcal were divided into either meals or snacks on the basis of contribution to daily energy intake (≥15% or snack frequency (independent variables) with dietary intake variables (dependent variables). Higher eating frequency was modestly and positively associated with higher HEI-2010 in both men and women; one additional eating occasion per day increased HEI-2010 by 1.77 points in men and 2.22 points in women (both Psnack frequency were also modestly and positively associated with HEI-2010 in both sexes, irrespective of the definition of meals and snacks. However, the associations were stronger for meal frequency than for snack frequency; one additional meal per day increased HEI-2010 by 2.14 to 5.35 points, and one additional snack per day increased HEI-2010 by 1.25 to 1.97 points (all Psnack frequency were modestly associated with better diet quality.

Local market prices in rural Bangladesh were used to compute the costs of filling the nutrient gaps between actual intakes and safe nutrient requirements, and the costs of compliance with nutrition messages, for 78 lactating mothers and 61 weaning-age breastfed children. (The gap is the difference between the requirement and the amount of nutrient consumed.) To fill the mother's energy gap of approximately 1050 kcal (4393 kJ) would cost an additional 21% of the daily wage, or almost double the value of food she was presently eating. Given social reality, these costs would probably be much greater, as the mother would also need to increase the allocation of food to other household members. The weaning-age children's energy gap could theoretically be closed for less than one-third of the cost of improving the mothers' diets, or about 8% of the daily wage. The increase in food intake equivalent to 2% of the daily wage actually achieved through nutrition education resulted in a significant improvement in child weight gain, though not ideal. These findings suggest that, in the absence of programs which reduce economic barriers, it is economically feasible for families to close the nutrient gaps for weaning-age breastfed children in Bangladesh, but not for lactating women. Thus, education to improve women's diets should be incorporated into programs that make these improvements affordable, whereas education to improve weaning-age children's diets can be implemented with or without other program supports.

Rabbit meat is a highly digestible, tasty, low-calorie food, often recommended by nutritionists over other meats. Currently research in the rabbit sector is interested in developing feeding strategies aiming to further increase the nutritional value of rabbit meat as a "functional food" by including n-3 polyunsaturated fatty acids (n-3 PUFA), conjugated linoleic acid (CLA), vitamins and antioxidants in rabbit diets and assessing their effects on both raw and stored/processed meat quality properties. Our recent studies indicate that the dietary inclusion from 3 to 6% of linseed might be considered as a way to achieve the enrichment of the meat with α-linolenic acid and to guarantee satisfactory product stability during further processing and storage. Considering that 6% dietary linseed corresponds to a n-3 PUFA content of 8.5% of the total fatty acids and a lipid content of 4.7 g/100 g of leg meat, a content of 396 mg n-3 PUFA/100g meat can be estimated, which represents about 19% of the recommended daily allowance (RDA) for n-3 PUFA.

Spaceflight impacts human physiology, including well documented immune system dysregulation. Diet, immune function, and the microbiome are interlinked, but diet is the only one of these factors that we have the ability to easily, and significantly, alter on Earth or during flight. As we understand dietary impacts on physiology more thoroughly, we may then improve the spaceflight diet to improve crew health and potentially reduce spaceflight-associated physiological alterations. It is expected that increasing the consumption of fruits and vegetables and bioactive compounds (e.g., omega-3 fatty acids, lycopene, flavonoids) and therefore enhancing overall nutritional intake from the nominal shelf-stable, fully-processed space food system could serve as a countermeasure to improve human immunological profiles, the taxonomic profile of the gut microbiota, and nutritional status, especially where currently dysregulated during spaceflight. This interdisciplinary study will determine the effect of the current shelf-stable spaceflight diet compared to an "enhanced" shelf-stable spaceflight diet (25% more foods rich in omega-3 fatty acids, lycopene, flavonoids, and more fruits, and vegetables in general). The NASA Human Exploration Research Analog (HERA) 2017 missions, consisting of four 45-day missions with closed chamber confinement and realistic mission simulation in a high-fidelity mock space vehicle, will serve as a platform to replicate mission stressors and the effects on crew biochemistry, immunology, and the gut microbiome. Bio sampling of crewmembers is scheduled for selected intervals pre- and in-mission. Data collection also includes dietary intake recording. Outcome measures will include immune markers (e.g., peripheral leukocyte distribution, inflammatory cytokine profiles, T cell function), the taxonomic and metatranscriptomic profile of the gut microbiome, and nutritional status biomarkers and metabolites. Statistical evaluations will determine physiological
Yogurt consumption is associated with higher nutrient intake, diet quality and favourable metabolic profile in children: a cross-sectional analysis using data from years 1-4 of the National diet and Nutrition Survey, UK.
Hobbs, D A; Givens, D I; Lovegrove, J A
Yogurt consumption has been associated with higher nutrient intakes, better diet quality and improved metabolic profiles in adults. Few studies have investigated these associations in children. This study investigated the association of yogurt consumption with nutrient intakes, diet quality and metabolic profile in British children. Data from 1687 children aged 4-10 and 11-18 years of the National Diet and Nutrition Survey (NDNS) years 1-4 were analysed. Yogurt consumption was determined using a 4-day diet diary. Diet quality was assessed by the Healthy Eating Index 2010 (HEI-2010). Anthropometric measures, blood pressure, pulse pressure, plasma glucose, HbA1c, C-reactive protein, triacylglycerol, total cholesterol, high-and low-density cholesterol from NDNS were used. The highest tertile of yogurt consumption (T3) was associated with higher nutrient intakes, particularly for calcium (children 4-10 years: P consumption was associated with significantly lower pulse pressure in children aged 4-10 years and lower HbA1c concentration, being shorter and having a larger hip circumference in children aged 11-18 years, compared with non-yogurt consumers. This study suggests that British children who are yogurt consumers (> 60 g/day) have higher overall diet quality, nutrient intakes and adequacy, lower pulse pressure (children aged 4-10 years) and HbA1c concentrations (children aged 11-18 years), were shorter and had a smaller hip circumference (children aged 11-18 years).

Conclusion: NE programmes have been effective in positive behavior modifi-cation measured in terms of eating pattern and health quality. Thus, it is recommended that health professionals use multiple intervention strategies at community level to ensure improved outcomes. Political support is also required to create culturally sensitive methods of delivering nutritional programmes. Finally, as policy is dependent on program cost, nutritional programmes need to combine methods of cost analysis to show cost effectiveness of supplying adequate nutrition for women throughout the lifecycle.

A nutrient-dense diet is a critical aspect in attaining optimal exercise training and athletic performance outcomes. Although including safe and effective nutritional supplements in the dietary design can be extremely helpful in promoting adequate caloric ingestion, they are not sufficient for promoting adequate caloric ingestion based on individualized caloric expenditure needs without the proper diet. Specifically, a strategic and scientifically based nutrient-dense dietary profile should be created by qualified professionals to meet the sport/exercise-specific energy demands of any individual involved in select training intensity protocols. Finally, ingesting the right quantity and quality of nutrient dense calories at precise windows of opportunity becomes vital in attaining desired training and/or competitive performance outcomes.

Continuity is required for diet therapy, but it depends on patients. We examined the utility of a new tool, the customized online nutrition guidance system, in patients with nonalcoholic fatty liver disease (NAFLD). Seven patients plotted their body weight (BW) and marked a customized task card on completion for 90 days on a website. The instructors encouraged them by e-mail. BW, serum transaminase levels, and system usage were evaluated. The results showed that BW and serum alanine aminotransferase levels were significantly lower than at baseline. BW and task visualization as well as encouragement by e-mails were effective in ensuring continuity. Thus, this system is effective in keeping NAFLD patients motivated to continue their diet therapy.

Obesity is a public health problem that disproportionately affects low-income populations. Moreover, participation in Supplemental Nutrition Assistance Program (SNAP) has been associated with obesity among low-income women. The goal of this study was to determine the impact of intrapersonal, home environment, community and social factors on diet quality and body mass index (BMI) of low-income women participating in SNAP. This study also aimed to examine the role of these factors in mediating the relationship between food insecurity and diet quality, and BMI. A total of 152 women receiving SNAP benefits were recruited from low-income neighborhood centers and housing communities, and administered a demographics questionnaire, the United States adult food security scale, food frequency questionnaire, and multi-dimensional home environment scale (MHES). They also were measured for height and weight to calculate BMI. The Dietary Guidelines Adherence Index 2015 was used to measure diet quality. Regression analyses were conducted to determine the MHES subscales that were significant predictors of diet quality and BMI. The Preacher and Hayes mediation model was used to evaluate the mediation of the relationship between food insecurity and diet quality, and BMI by the MHES. Emotional eating resistance and favorable social eating behaviors were positively associated with diet quality; whereas emotional eating resistance, lower availability of unhealthy food at home, neighborhood safety and favorable social eating behaviors were inversely associated with BMI in women participating in SNAP. The MHES significantly mediated the relationship between food insecurity and BMI. These results emphasize the importance of intrapersonal, home environment, community and social factors in mediating the relationship between food insecurity and BMI in low-income women.

We examined whether acute and/or chronic skeletal muscle anabolism is impaired with a low-carbohydrate diet formulated to elicit ketosis (LCKD) vs. a mixed macronutrient Western diet (WD). Male Sprague-Dawley rats (9-10 wk of age, 300-325 g) were provided isoenergetic amounts of a LCKD or a WD for 6 wk. In AIM 1, basal serum and gastrocnemius assessments were performed. In AIM 2, rats were resistance exercised for one bout and were euthanized 90-270 min following exercise for gastrocnemius analyses. In AIM 3, rats voluntarily exercised daily with resistance-loaded running wheels, and hind limb muscles were analyzed for hypertrophy markers at the end of the 6-wk protocol. In AIM 1, basal levels of gastrocnemius phosphorylated (p)-rps6, p-4EBP1, and p-AMPKα were similar between diets, although serum insulin (P ketosis, as the LCKD-fed rats in AIM 2 exhibited ∼1.5-fold greater serum β-hydroxybutyrate levels relative to WD-fed rats (diet effect P = 0.003). This study demonstrates that the tested LCKD in rodents, while only eliciting mild nutritional ketosis, does not impair the acute or chronic skeletal muscle hypertrophic responses to resistance exercise.

Exposure to a maternal junk food (JF) diet in utero and during the suckling period has been demonstrated to increase the preference for palatable food and increase the susceptibility to diet-induced obesity in adult offspring. We aimed to determine whether the effects of prenatal exposure to JF could be ameliorated by cross-fostering offspring onto dams consuming a standard rodent chow during the suckling period. We report here that when all offspring were given free access to the JF diet for 7 weeks from 10 weeks of age, male offspring of control (C) or JF dams that were cross-fostered at birth onto JF dams (C-JF, JF-JF), exhibited higher fat (C-C: 12.3 ± 0.34 g/kg/day; C-JF: 14.7 ± 1.04 g/kg/day; JF-C: 11.5 ± 0.41 g/kg/day; JF-JF: 14.0 ± 0.44 g/kg/day; P food intake, had increased fat mass as percentage of body weight (C-C: 19.9 ± 1.33%; C-JF: 22.8 ± 1.57%; JF-C: 17.4 ± 1.03%; JF-JF: 22.0 ± 1.0%; P food preferences in females and susceptibility to diet-induced obesity in males can be prevented by improved nutrition during the suckling period.

Sausage samples were prepared using a five-level three-variable Central Composite Rotatable Design with 16 combinations, including two replicates of the center point, carried out in random order. The level of brisket fat (BF), soy protein isolate (SPI), and cornstarch (CS) in the sausage formulation ranged within 8.3–16.7%, 0.7–2.3%, and 1.3–4.7%, respectively. Increasing BF decreased moisture and ash contents but increased protein and fat contents of the sausages (p sausages (p sausages than CS. PMID:28706941

The Dietary Approaches to Stop Hypertension (DASH) diet is associated with lower blood pressure and reduced risk of cardiovascular disease among adults, but little is known about accordance with this dietary pattern or health benefits among children and adolescents. The objectives were to evaluate accordance with the DASH diet, differences over time, and the association with health attributes among a nationally representative sample of US children and adolescents. Cross-sectional data from the 2003-2012 National Health and Nutrition Examination Surveys (NHANES) were analyzed. Data from 9,793 individuals aged 8 to 18 years were examined. DASH accordance was estimated based on nine nutrient targets: total fat, saturated fat, protein, cholesterol, fiber, calcium, magnesium, potassium, and sodium; possible score range is 0 to 9. Accordance with the DASH diet across time was examined comparing the 2011-2012 to 2003-2004 NHANES surveys. The association between DASH score and weight status was examined using multinomial logistic regression, and the associations with waist circumference, systolic blood pressure, and diastolic blood pressure were examined using multivariable linear regression. Accordance with the DASH diet was low across the age groups, with a range of mean DASH scores from 1.48 to 2.14. There were no significant changes across time. DASH score was inversely associated with systolic blood pressure (mm Hg) among 14- to 18-year-olds (β=-.46; 95% CI -.83 to -.09) among the larger sample of participants who completed at least one dietary recall, but no significant differences were seen in other age categories. In the subsample of participants with both dietary recalls, a significant inverse association was seen between DASH score and systolic blood pressure for 11- to 13-year-olds (β=-.57; 95% CI -1.02 to -.12). There were no significant associations between this dietary pattern and weight status, waist circumference, or diastolic blood pressure. Few US

The aim of this paper is to provide a methodological approach to evaluate the nutritional sustainability of typical agro-food products, representing Mediterranean eating habits and included in the Mediterranean food pyramid. For each group of foods, suitable and easily measurable indicators were identified. Two macro-indicators were used to assess the nutritional sustainability of each product. The first macro-indicator, called 'business distinctiveness', takes into account the application of different regulations and standards regarding quality, safety and traceability as well as the origin of raw materials. The second macro-indicator, called 'nutritional quality', assesses product nutritional quality taking into account the contents of key compounds including micronutrients and bioactive phytochemicals. For each indicator a 0-10 scoring system was set up, with scores from 0 (unsustainable) to 10 (very sustainable), with 5 as a sustainability benchmark value. The benchmark value is the value from which a product can be considered sustainable. A simple formula was developed to produce a sustainability index. The proposed sustainability index could be considered a useful tool to describe both the qualitative and quantitative value of micronutrients and bioactive phytochemical present in foodstuffs. This methodological approach can also be applied beyond the Mediterranean, to food products in other world regions. © 2018 Society of Chemical Industry. © 2018 Society of Chemical Industry.

Background In developing countries, deficiencies in essential micronutrients are common, particularly in pregnant women. Although, biochemical indicators of diet and nutrition are useful to assess nutritional status, few studies have examined such indicators throughout pregnancy in women in developing countries. Methods The primary objective of this study was to assess the nutritional status of 78 Peruvian women throughout pregnancy for 16 different nutritional indicators including fat-soluble vitamins and carotenoids, iron-status indicators, and selenium. Venous blood samples from which serum was prepared were collected during trimesters one (n = 78), two (n = 65), three (n = 62), and at term via the umbilical cord (n = 52). Questionnaires were completed to determine the demographic characteristics of subjects. Linear mixed effects models were used to study the associations between each maternal indicator and the demographic characteristics. Results None of the women were vitamin A and E deficient at any stage of pregnancy and only 1/62 women (1.6%) was selenium deficient during the third trimester. However, 6.4%, 44% and 64% of women had ferritin levels indicative of iron deficiency during the first, second and third trimester, respectively. Statistically significant changes (p ≤ 0.05) throughout pregnancy were noted for 15/16 nutritional indicators for this Peruvian cohort, with little-to-no association with demographic characteristics. Three carotenoids (beta-carotene, beta-cryptoxanthin and trans-lycopene) were significantly associated with education status, while trans-lycopene was associated with age and beta-cryptoxanthin with SES (p Peruvian women was expected. It was surprising though not to find deficiencies in other nutrients. The results highlight the importance of continual monitoring of women throughout pregnancy for iron deficiency which could be caused by increasing fetal needs and/or inadequate iron intake as pregnancy

A 26-week nutrition intervention, including 4 weeks of nutrition education, combined with an increase in the content and bioavailability of dietary iron for 22 weeks was carried out in 34 intervention and 34 control adolescent girls suffering from mild iron deficiency anemia (IDA). In post-intervention, hemoglobin and serum ferritin were significantly higher in the intervention group, whereas the incidence of IDA was significantly lower in the intervention group compared to the control group. Nutrition knowledge scores were significantly higher in intervention girls compared to control girls. Dietary changes to improve available dietary iron can reduce iron deficiency anemia.

1. Four experimental diets containing 0, 0.5, 1.0 and 2.0% fermented pomegranate by-products (FPB) were supplied to 320d-old broilers to evaluate the effects of FPB on growth performance, nutritional composition, fatty acid profile and oxidative stability of meat. 2. Dietary supplementation of FPB linearly increased the weight gain and feed intake of broilers with linear reduction in feed conversion ratio. 3. The crude protein, iron, magnesium, and sodium content were linearly higher, whereas cholesterol was linearly lower in the breast meat of FPB-supplemented broilers. In thigh meat, linearly lower ether extract and cholesterol with higher moisture was noted in response to increasing levels of FPB. 4. The proportion of saturated fatty acids was both linearly and quadratically lower in breast and thigh meat, whereas those of monounsaturated fatty acids of breast (linear and quadratic) and n-3 fatty acids of breast and thigh (linear) meat was higher in the FPB-supplemented broilers. The n-6/n-3 ratio of breast meat was linearly lower in response to FPB supplementation. The hypocholesterolaemic to hypercholesterolaemic ratio of thigh meat was higher in the FPB-supplemented groups. 5. The thiobarbituric acid reactive substances and pH value were lower in the breast and thigh meat of FPB-supplemented broilers. 6. Thus, additive supplementation of the diet with up to 2% FPB improved the nutritional quality, fatty acid profile and shelf life of broiler meat.

Chronic diseases are currently the major cause of death and disability worldwide. Addressing the main causes of chronic diseases from a preventive perspective is imperative for half ing a continual increase in premature deaths. Physicians occupy a unique position to assist individuals with chronic disease prevention. Hence, medical school is an opportunity to prepare physicians for preventive interventions with patients at risk for developing chronic diseases. This study asserts that education on chronic disease prevention that targets tobacco cessation/prevention, nutrition/ diet, and exercise physiology/fitness is a key aspect of medical school curricula. However, many US medical schools do not include all 3 components in their curricula. This study investigates the extent to which medical school curricula include the above 3 areas. Two methods were utilized for the study: (1) a cross-sectional survey was given to the associate dean of academic affairs of 129 US medical schools and (2) relevant data were retrieved from the Association of American Medical Colleges. Findings support the notion that medical schools are in need of increased curricula covering tobacco prevention/cessation, nutrition/diet, and exercise physiology/fitness. Results indicate that exercise physiology/fitness was the area receiving the least attention in medical schools. Ultimately, this study's purpose was to provide a basis for determining whether inclusion of these 3 subjects in medical school curricula has any significant effect on training future doctors to meet the needs of growing numbers of individuals with chronic disease.
A Historical Review of Changes in Nutrition Standards of USDA Child Meal Programs Relative to Research Findings on the Nutritional Adequacy of Program Meals and the Diet and Nutritional Health of Participants: Implications for Future Research and the Summer Food Service Program.
Hopkins, Laura C; Gunther, Carolyn
The USDA child meal programs (CMPs) (National School Lunch Program (NSLP), School Breakfast Program (SBP), and Summer Food Service Program (SFSP) were established in 1946 (NSLP) and 1975 (SBP and SFSP) to improve the diet and nutritional health of US children. There is concern that participation in these programs may in fact be a contributor to the current childhood obesity epidemic. The purpose of this study was to determine if the CMPs are meeting their intended goal by reviewing the historical changes to nutrition standards of the CMPs in correspondence with the literature that examines the nutritional adequacy of meals served as part of these programs, as well as the dietary intakes and nutritional status of participants. Public Law and the Federal Register were reviewed and websites and online databases were systematically searched. NSLP and SBP first underwent updates to the nutrition standards in 1994 and subsequently 2010, whereas SFSP last underwent modifications in 2000. The majority of data, all collected prior to 2010, demonstrate that meals served as part of the NSLP and SBP are not meeting nutrition standards. In addition, the dietary intakes of NSLP and SBP participants are high in calories, fat, saturated fat, and sodium, and low in fiber. Studies examining the weight status and other nutrition-related health outcomes of NSLP and SBP participants have produced mixed results. In contrast, no studies published in the peer-reviewed literature have been conducted examining the nutritional adequacy of SFSP meals or the dietary intakes or nutritional health of SFSP participants. There are public reports available on the nutritionally adequacy of SFSP meals, however, they are severely outdated (1988 and 2003). Due to this dearth of information, a case study on a sample SFSP menu from summer 2015 was conducted; results showed that the meals are high in carbohydrate and protein content and insufficient in vegetable servings.

Full Text Available Foram avaliados o desempenho da desmama ao abate e as características de carcaça de 144 coelhos da raça Nova Zelândia Branco, oriundos de matrizes alimentadas com dietas referência ou semi-simplificada com 79,83% de subprodutos de mandioca, distribuídos em gaiolas, em esquema fatorial 2 x 3 (duas rações fornecidas às matrizes e láparos até a desmama versus três rações fornecidas aos animais da desmama até o abate com 12 repetições e dois animais por unidade experimental. As dietas fornecidas, após a desmama, consistiram de umareferência e duas semi-simplificadas com 81,63% de subprodutos de mandioca ensilados ou não antes da sua incorporação. Coelhos cujas mães foram alimentadas com dieta semi-simplificadas se apresentaram mais leves à desmama que os desmamados com dieta-referência. Observou-se menor consumo de ração para os coelhos que receberam a dieta maternidade semi-simplificada até a desmama, resultando em melhor conversão alimentar. Os pesos da carcaça e dos cortes comerciais foram maiores nos animais alimentados com as rações referência maternidade e referência crescimento. O uso de dietas semi-simplificadas com subprodutos de mandioca ensilados ou não, da desmama ao abate, reduziu o ganho de peso diário e o consumo de ração,porém melhorou a conversão alimentar e diminuiu o custo de ração. A utilização das rações semi-simplificadas apresenta-se como alternativa interessante para a produção de coelhos.This study evaluated the performance from weaning to slaughter and carcass characteristics of 144 New Zealand White rabbits, from does fed with a reference diet or half-simplified diet containing 79.83% cassava by-product, allocated in iron cages, in a 2 x 3 factorialarrangement (two diets used for does and litters until weaning versus three diets supplied for animals from weaning to slaughter with 12 replications and two animals per experimental unit.

This study explored the effects of supplemental dietary extra virgin olive oil (EVOO), gallic acid (GA), or lemongrass essential oil (LGEO) on growth performance, nutrient digestibility, carcass traits, lipid peroxidation, hematological, and antioxidative status in growing rabbits under heat stress conditions. A total of 48 male growing New Zealand White rabbits were randomly divided into four equal groups, which received a basal diet without any supplementation or supplemented with 15 g EVOO, 500 mg GA, or 400 mg LGEO/kg of diet, for eight consecutive weeks. Results revealed that the overall mean of temperature humidity index was 84.67 ± 0.35, reflecting a state of severe heat stress. Moreover, dietary supplementation with EVOO, GA, or LGEO significantly increased live body weight and daily body weight gain but decreased both feed conversion ratio and daily water consumption. Additionally, a significant increase in both organic matter and crude protein digestibility besides a remarkable elevation in the nutritive values of digestible crude protein, total digestible nutrients, and digestible energy, as well as an increase in the numbers of WBCs, lymphocytes, and heterophils was significant in EVOO-supplemented rabbits. Supplementation with EVOO, GA, or LGEO in the heat-stressed growing rabbit's diet enhanced catalase activity and reduced glutathione content, whereas EVOO-treated rabbits had the highest values. Also, malondialdehyde activity was reduced in response to all tested additives. In conclusion, these findings suggested that addition of EVOO, GA, or LGEO in growing rabbit's diet could be used effectively to alleviate negative impacts of heat stress load on performance, nutrient digestibility, oxidative status, and hemato-biochemical features. Furthermore, among these additives, EVOO achieved the best effects.
Enhancement of solubility and therapeutic potential of poorly soluble lovastatin by SMEDDS formulation adsorbed on directly compressed spray dried magnesium aluminometasilicate liquid loadable tablets: A study in diet induced hyperlipidemic rabbits
Mohd Javed Qureshi
Full Text Available The aim of present study was to formulate and evaluate a self-microemulsifying drug delivery systems (SMEDDS containing lovastatin and to further explore the ability of porous Neusilin® US2 tablet as a solid carrier for SMEDDS. SMEDDS formulations of varying proportions of peceol, cremophor RH 40 and transcutol-P were selected and subjected to in-vitro evaluation, including dispersibility studies, droplet size, zeta potential measurement and release studies. The results indicated that the drug release profile of lovastatin from SMEDDS formulations was statistically significantly higher (p-value < 0.05 than the plain lovastatin powder. Thermodynamic stability studies also confirmed the stability of the prepared SMEDDS formulations. The optimized formulation, which consists of 12% of peceol, 44% of cremophor RH 40, and 44% of transcutol-P was loaded into directly compressed liquid loadable tablet of Neusilin® US2 by simple adsorption method. In order to determine the ability of Neusilin® US2 as a suitable carrier pharmacodynamics study were also carried out in healthy diet induced hyperlipidemic rabbits. Animals were administered with both liquid SMEDDS and solid SMEDDS as well. From the results obtained, Neusilin® was found to be a suitable carrier for SMEDDS and was equally effective in reducing the elevated lipid profile. In conclusion, liquid loadable tablet (LLT is predicted to be a promising technique to deliver a liquid formulation in solid state.

Feeding programs promoting daily feed intake (DFI) stability in rabbit males could be useful to ensure successful coverage of their nutritional requirements and for continued production of quality semen. To evaluate two feeding systems designed to reduce DFI variability, 115 rabbit males at age 1.2 years were randomly assigned to three different treatments for 294 days: CS, animals fed ad libitum with a control diet (127-g starch and 281-g total soluble fiber [hemicellulose + soluble fiber] kg(-1) dry matter); SF, males fed ad libitum with diet enriched in soluble fiber (86-g starch and 330-g total soluble fiber kg(-1) dry matter); and R, animals fed with CS diet but daily restricted to maintenance requirements. Feed intake, body weight, body condition, and variability of DFI were controlled every 42 days, and individual semen volume and sperm motility, concentration, acrosome status, and abnormalities every 15 days. In six commercial farms, the number of females inseminated, pregnant and kindling, as well as the number of kits born alive, was registered for 15,893 inseminations with pooled semen from each treatment. DFI was significantly lower for R males than for the other treatments (on average, -12 ± 4 g/day; P fertility of their pooled semen. Copyright © 2016 Elsevier Inc. All rights reserved.

Full Text Available Abstract In a "nutrition transition", the consumption of foods high in fats and sweeteners is increasing throughout the developing world. The transition, implicated in the rapid rise of obesity and diet-related chronic diseases worldwide, is rooted in the processes of globalization. Globalization affects the nature of agri-food systems, thereby altering the quantity, type, cost and desirability of foods available for consumption. Understanding the links between globalization and the nutrition transition is therefore necessary to help policy makers develop policies, including food policies, for addressing the global burden of chronic disease. While the subject has been much discussed, tracing the specific pathways between globalization and dietary change remains a challenge. To help address this challenge, this paper explores how one of the central mechanisms of globalization, the integration of the global marketplace, is affecting the specific diet patterns. Focusing on middle-income countries, it highlights the importance of three major processes of market integration: (I production and trade of agricultural goods; (II foreign direct investment in food processing and retailing; and (III global food advertising and promotion. The paper reveals how specific policies implemented to advance the globalization agenda account in part for some recent trends in the global diet. Agricultural production and trade policies have enabled more vegetable oil consumption; policies on foreign direct investment have facilitated higher consumption of highly-processed foods, as has global food marketing. These dietary outcomes also reflect the socioeconomic and cultural context in which these policies are operating. An important finding is that the dynamic, competitive forces unleashed as a result of global market integration facilitates not only convergence in consumption habits (as is commonly assumed in the "Coca-Colonization" hypothesis, but adaptation to

Full Text Available The paper presents the most important parasitic infections of wild rabbits and hares, which harmful effect in this animal population is manifested as a gradual weakening of the immune system, reduction in fertility, weight loss and constant exhaustion. Order of Lagomorpha (hares or lagomorphs belongs to superorder of higher mammals which includes the family of rabbits (Leporidae which are represented in Europe as well as the family of whistleblowers (Ochotonidae which live only in North America and Northern regions of Asia. The most important representatives of Leporidae family are European hare (Lepus europeus and wild rabbit (Oryctolagus cuniculus. The most important endoparasitosis of hares and wild rabbits are: coccidiosis, encephalitozoonosis (nosemosis, toxoplasmosis, sarcocystosis, giardiasis, cryptosporidiosis, protostrongylosis, trichostrngylodosis, passalurosis, anoplocephalidosis, cysticercosis and fasciolosis. The most frequent ectoparasites of rabbits and wild hares are fleas, lice and ticks. Reduction in hare population, which is noticed in whole Europe including Serbia, is caused by changed living conditions, quantitatively and qualitatively insufficient nutrition, increased use of herbicides as well as various infectious diseases and the diseases of parasitic etiology. Since wild rabbits and hares pose a threat to health of domestic rabbits and people, knowledge of parasitic fauna of these wild animals is of extreme epizootiological and epidemiological importance.

Full Text Available This experiment was carried out to evaluate the effect of mixed algal diet on dietary profiles of copepods. The microalgae like Spirulina platensis, Chlorella vulgaris and Azolla pinnata were mass cultured in artificial medium for a period of 20 days, cells are harvested, dried, powdered and used as feed. The small freshwater cyclopoids Thermocyclops hyalinus were compared to Mesocyclops aspericornis a species of copepod genera commonly preferred by most of the fish larvae. Both species are easily maintained in culture, when fed with mixed algal diets of equal ratios (1:1:1. Biochemical composition, egg production ratios, growth performance and fatty acids profile of the two different species were analyzed after an experimental period of 15 days, all the nutritional values were found to be high and statistically variable. On the basis of biochemical composition, egg production ratio, growth performance, amino acids and fatty acids profile it is found that M. aspericornis was the suitable candidate for larval fish diets.

Two trials were carried out to compare the nutritional values of two Zambian indigenous plant protein sources--soy bean cake (SBC) and sunflower meal (SFM) in the diets of broilers and growing pigs. In trial 1, 120 one week old chickens (Abbor acre strain) were used. There were no differences (P > 0.05) between chickens on SBC and SFM in voluntary feed intake. Average daily gain of SBC chickens differed (P < 0.05) from those of SFM. The protein source had an effect (P < 0.05) on N retained [g/day]. Carcasses dry matter and crude protein were higher (P < 0.05) in SBC chickens, but ash, ether extract, Ca and P were the same as SFM. In trial 2, 12 Large white x Landrace growing barrows 1-2 months old were used. In this trial, SBC diet was consumed more than SFM. Pigs on SBC and SFM gained 0.526 and 0.284 g/head/day, respectively (P < 0.05). Nutrient digestibility was higher (P < 0.05) in SBC diet. Trial 1, demonstrated that SBC and SFM could be used for broilers without adverse effect on growth rate and body conformation. However, for growing pigs SBC is a better protein source than SFM in the tropical environment of Zambia. Finally, results obtained seem to suggest that SBC and SFM can be used as plant protein sources, but SFM is not an ideal plant protein source for growing pigs.
Full Text Available In many countries of Europe rabbit meat is consumed for its nutritional characteristics, (Dalle Zotte, 2014; Hernández and Gondret, 2006. Since the ban of the use of antibiotic as growth promoter, natural substances have been studied as alternative with antioxidant, anti-inflammatory, antimicrobic and antiviral properties. The aim was to evaluate the effect of a dietary supplementation with natural extract mixture in growing rabbit on growth performances, carcass characteristics and Longissimus lumborum (LL muscle parameters. The trial was performed at the Research Institute for Animal Production (Nitra, Slovak Republic and lasted 42 days. At 35 days of age, 144 New Zealand White rabbits were randomly selected and divided in 3 experimental groups (4 rabbits/cage. The first fed a basal diet, the second (T1 and the third one (T2 received 0.3% and 0.6% of natural extract mixture, containing polyphenols from plants and seaweeds. Dietary integration with natural extract improve (P<0.05 growth performances (ADG, FI and FC in T1 group. The fatty acid composition of LL muscle was positively affected (P=0.037 by natural extract supplementation with an increase of n-3 FA in T2 group than other treatments. Cholesterol content tended to be lower in T2 group (P=0.082 than T1 and C group (24.8 mg/100g T2 vs 34.6 mg/100g T1 vs 33.2 mg/100g C. Sensory analysis revealed that only the aroma was affected (P<0.05 by dietary treatments. Overall these results highlight that dietary supplementation with natural extract mixture, containing polyphenols from plants and seaweeds enhance growth performances, carcass weight, improving LL muscle nutritional parameters.

Terminal cancer-associated cachexia, characterized by a marked weight loss, anorexia, asthenia and anemia, is usually associated with a malnutrition status. To investigate whether a diet formulated with a crayfish enzymatic extract, enriched in essential amino acids, omega-3 fatty acids, and astaxanthin, would be effective for the treatment of cancer-associated cachexias, by decreasing mortality and morbidity rates in cachectic rats and/or improving survival. Two types of diet were used: a standard diet and one formulated with crayfish enzymatic extract. Rats were divided into two groups (24 animals per group): one without tumor (T-) and the other with tumor (T+) (AH-130 Yoshida ascites hepatoma). Each group was further divided into two subgroups (12 animals per subgroup). Two subgroups (T-(standard) and T+(standard)) were fed the standard diet and the other two (T-(CFEE) and T+(CFEE)) the crayfish enzymatic extract one for four weeks, after which different tissue and plasma parameters were studied. The implantation of the tumor resulted in a considerable loss of muscle and adipose tissue mass in both groups, but the loss of muscle and fat was lower in the group fed the crayfish enzymatic extract diet. There was also a concomitant increase in the plasma concentration of TNF-alpha, although the increase was smaller in the crayfish enzymatic extract-treated group. This study shows that although the treatment of cachetic rats with the crayfish enzymatic extract diet did not revert the cachexia, it increased survival (57.1% vs. 25.9% in the group treated with crayfish enzymatic extract and standard diets, respectively) and meliorated the cachexia symptoms--anorexia and body mass loss (muscle and adipose tissue).

The soldierâ s diet in the Civil War has been known as poor, and a number of illnesses and disorders have been associated with it. However, a nutritional analysis placed within the context of mid-nineteenth century American nutrition has been lacking. Such an approach makes clear the connection between illness and diet during the war for the average soldier and defines the importance of nutritionâ s role in the war. It also provides a bridge from the American diet to the soldier diet, ou...

Full Text Available Ever more evidence associates short sleep with increased risk of metabolic diseases such as obesity, which may be related to a predisposition to non-homeostatic eating. Few studies have concurrently determined associations between sleep duration and objective measures of metabolic health as well as sleep duration and diet, however. We therefore analyzed associations between sleep duration, diet and metabolic health markers in UK adults, assessing associations between sleep duration and 1 adiposity, 2 selected metabolic health markers and 3 diet, using National Diet and Nutrition Survey data. Adults (n = 1,615, age 19-65 years, 57.1% female completed questions about sleep duration and 3 to 4 days of food diaries. Blood pressure and waist circumference were recorded. Fasting blood lipids, glucose, glycated haemoglobin (HbA1c, thyroid hormones, and high-sensitivity C-reactive protein (CRP were measured in a subset of participants. We used regression analyses to explore associations between sleep duration and outcomes. After adjustment for age, ethnicity, sex, smoking, and socioeconomic status, sleep duration was negatively associated with body mass index (-0.46 kg/m2 per hour, 95% CI -0.69 to -0.24 kg/m2, p < 0.001 and waist circumference (-0.9 cm per hour, 95% CI -1.5 to -0.3cm, p = 0.004, and positively associated with high-density lipoprotein cholesterol (0.03 mmol/L per hour, 95% CI 0.00 to 0.05, p = 0.03. Sleep duration tended to be positively associated with free thyroxine levels and negatively associated with HbA1c and CRP (p = 0.09 to 0.10. Contrary to our hypothesis, sleep duration was not associated with any dietary measures (p ≥ 0.14. Together, our findings show that short-sleeping UK adults are more likely to have obesity, a disease with many comorbidities.

To examine the association between adherence to the Dutch Guidelines for a Healthy Diet created by the Dutch Health Council in 2006 and overall and smoking-related cancer incidence. Prospective cohort study. Adherence to the guidelines, which includes one recommendation on physical activity and nine on diet, was measured using an adapted version of the Dutch Healthy Diet (DHD) index. The score ranged from 0 to 90 with a higher score indicating greater adherence to the guidelines. We estimated the hazard ratios (HR) and 95 % confidence intervals for the association between the DHD index (in tertiles and per 20-point increment) at baseline and cancer incidence at follow-up. We studied 35 608 men and women aged 20-70 years recruited into the European Prospective Investigation into Cancer and Nutrition-Netherlands (EPIC-NL) study during 1993-1997. After an average follow-up of 12·7 years, 3027 cancer cases were documented. We found no significant association between the DHD index (tertile 3 v. tertile 1) and overall (HR = 0·97; 95 % CI 0·88, 1·07) and smoking-related cancer incidence (HR = 0·89; 95 % CI 0·76, 1·06) after adjustment for relevant confounders. Excluding the components physical activity or alcohol from the score did not change the results. None of the individual components of the DHD index was significantly associated with cancer incidence. In the present study, participants with a high adherence to the Dutch Guidelines for a Healthy Diet were not at lower risk of overall or smoking-related cancer. This does not exclude that other components not included in the DHD index may be associated with overall cancer risk.

To examine how different definitions of meals and snacks can affect the associations of meal frequency (MF) and snack frequency (SF) with dietary intake and adiposity measures. Based on 7 d weighed dietary record data, all eating occasions providing ≥210 kJ of energy were divided into meals or snacks based on contribution to energy intake (≥15 % or snacks, SF was associated with higher intakes of confectionery and alcohol, lower intakes of cereals, protein, fat and dietary fibre, and lower HDI (except for SF based on energy contribution in women) and MDS. After adjustment for potential confounders, MF based on time, but not MF based on energy contribution, was positively associated with BMI and waist circumference in men only. SF was positively associated with BMI and waist circumference, irrespective of the definition of snacks. Higher SF was consistently associated with lower diet quality and higher adiposity measures, while associations with MF varied depending on the definition of meals and sex.
