    Full Text Available Introduction: Diabetes, characterized by high blood glucose levels, is a serious chronic disease and antioxidant play an important role in the pathophysiology, complications, and management of the disease. Kudzu root, a traditional Chinese herbal medicine, has a long history of use for the treatment of headaches, cough, edema and extracts are a rich source of isoflavones and antioxidants property. The aim of this study was to evaluate the effect of the kudzu root on biochemical parameters in streptozotocin-induced diabetic rats. Methods: Male wistar rats were divided into four groups (n=32 including: Control, diabetic, diabetic rats treated with 100 mg/kg kudzu root extract, and diabetic rats treated with 50mg/kg kudzu root extract. Diabetes was induced by STZ intraperitoneally administration (50 mg/kg and kudzu root extract was gavaged at the dose of 50 and 100 mg/kg for five weeks. Blood biochemical factors and insulin serum levels were also assessed. Results: The results show that in STZ induced diabetic rats, the serum levels of FBS, total cholesterol (TC and triglyceride (TG increased whiles the levels of HDL and Insulin were decreased. Moreover in diabetic kudzu treatment groups, the serum levels of of FBS, total cholesterol (TC and triglyceride(TG decreased (P≤0.001 whiles the serum level of HDL and Insulin were increased. Conclusion: In addition the antioxidant effects, Kudzu root extract produced a significant anti-hyperglycemic effect on STZ-induced diabetic rats.

    Kudzu is an aggressive, nonnative vine that currently dominates an estimated 810,000 ha of mesic forest communities in the eastern United States. To test an integrated method of weed control, abundances of kudzu and other plant species were compared during 4 yr after six herbicide treatments (clopyralid, triclopyr, metsulfuron, picloram 1 2,4-D, tebuthiuron, and a nonsprayed check), in which loblolly pines were planted at three densities (0, 1, and 4 seedlings m22) to induce competition and potentially delay kudzu recovery. This split-plot design was replicated on each of the four kudzu-dominated sites near Aiken, SC. Relative light intensity (RLI) and soil water content (SWC) were measured periodically to identify mechanisms of interference among plant species. Two years after treatment (1999), crown coverage of kudzu averaged , 2% in herbicide plots compared with 93% in the nonsprayed check, and these differences were maintained through 2001, except in clopyralid plots where kudzu cover increased to 15%. In 2001, pine interference was associated with 33, 56, and 67% reductions in biomass of kudzu, blackberry, and herbaceous vegetation, respectively. RLI in kudzu-dominated plots (4 to 15% of full sun) generally was less than half that of herbicide-treated plots. SWC was greatest in tebuthiuron plots, where total vegetation cover averaged 26% compared with 77 to 111% in other plots. None of the treatments eradicated kudzu, but combinations of herbicides and induced pine competition delayed its recovery.

    There is a growing concern that dietborne metal toxicity might be important in aquatic ecosystems. However, the science behind this matter is insufficiently developed to explicitly and accurately account for this in metal regulation or risk assessment. We investigated the effects of a chronic exposure of Daphnia magna to an elevated level of Cu (3000 microg Cu/g dry wt) in their diet (the green alga Pseudokirchneriella subcapitata). Compared to daphnids fed with P. subcapitata containing a background of 10.6 microg Cu/g dry wt, daphnids fed for 21 days with this Cu-contaminated food accumulated a total copper body burden of 325 microg Cu/g dry wt, which is about 30-fold higher than the control body burden of 12.1 microg/g dry wt. The exposed daphnids experienced a 38% reduction of growth (measured as final dry body weight), a 50% reduction of reproduction (total number of juveniles produced per daphnid), and only produced three broods versus four broods by the control daphnids. Unlike most other studies, we were able to demonstrate that these effects were most likely not due to a reduced nutritional quality of the food, based on C:P ratios and fatty acid content and composition of the Cu-contaminated algae. Life-history analysis showed that time to first brood was not affected by dietary Cu, while the second and third broods were significantly delayed by 0.7 and 1.5 days, respectively. On the other hand, brood sizes of all three broods were significantly lower in Cu exposed daphnids, i.e. by 32-55%. The variety of effects observed suggest the possible, and perhaps simultaneous, involvement of several toxicity mechanisms such as increased metabolic cost, reduced energy acquisition (potentially via inhibition of digestive enzyme activity), targeted inhibition of reproduction (potentially via inhibition of vitellogenesis), and/or direct inhibition of molting. Further research is needed to differentiate between these postulated mechanisms of dietary Cu toxicity and to

    The progression and exacerbations of chronic obstructive pulmonary disease (COPD) are intimately associated with tobacco smoke/biomass fuel-induced oxidative and aldehyde/carbonyl stress. Alterations in redox signaling proinflammatory kinases and transcription factors, steroid resistance, unfolded protein response, mucus hypersecretion, extracellular matrix remodeling, autophagy/apoptosis, epigenetic changes, cellular senescence/aging, endothelial dysfunction, autoimmunity, and skeletal muscle dysfunction are some of the pathological hallmarks of COPD. In light of the above it would be prudent to target systemic and local oxidative stress with agents that can modulate the antioxidants/ redox system or by boosting the endogenous levels of antioxidants for the treatment and management of COPD. Identification of various antioxidant agents, such as thiol molecules (glutathione and mucolytic drugs, such as N-acetyl-L-cysteine, N-acystelyn, erdosteine, fudosteine, ergothioneine, and carbocysteine lysine salt), dietary natural product-derived polyphenols and other compounds (curcumin, resveratrol, green tea catechins, quercetin sulforaphane, lycopene, acai, alpha-lipoic acid, tocotrienols, and apocynin) have made it possible to modulate various biochemical aspects of COPD. Various researches and clinical trials have revealed that these antioxidants can detoxify free radicals and oxidants, control expression of redox and glutathione biosynthesis genes, chromatin remodeling, and ultimately inflammatory gene expression. In addition, modulation of cigarette smoke-induced oxidative stress and related cellular changes have also been reported to be effected by synthetic molecules. This includes specific spin traps like α-phenyl-N-tert-butyl nitrone, a catalytic antioxidant (ECSOD mimetic), porphyrins (AEOL 10150 and AEOL 10113), and a superoxide dismutase mimetic M40419, lipid peroxidation and protein carbonylation blockers/inhibitors, such as edaravone and lazaroids

    Investigation of the relationship between dietary patterns and some chronic noncommunicable diseases has become appealing in nutritional epidemiology. Some studies have reported potential associations between dietary patterns and the risk of chronic obstructive pulmonary disease; however, the results remain conflicting. Thus, we conducted this meta-analysis to pool the results of studies to clarify the associations between dietary patterns and the risk of chronic obstructive pulmonary disease. A literature search of MEDLINE and EBSCO databases was performed to identify relevant studies published from January 1990 up to June 2015. A total of 13 studies met the inclusion criteria and were included in this meta-analysis. The highest category of healthy/prudent dietary patterns when compared with the lowest category was apparently associated with a decreased risk (OR = 0.55; CI: 0.46, 0.66; P < 0.0001). An increase in the risk of chronic obstructive pulmonary disease was shown for the highest compared with the lowest categories of "unhealthy/western-style" dietary patterns (OR = 2.12; CI: 1.64, 2.74; P < (0.0001). The results of this meta-analysis indicate that different dietary pattern may be associated with the risk of chronic obstructive pulmonary disease. PMID:26678388

    These studies were performed to test the benefit of resistant starch on ulcerative colitis via prebiotic and butyrate effects. Butyrate, propionate, and acetate are produced in the colon of mammals as a result of microbial fermentation of resistant starch and other dietary fibers. Butyrate plays an important role in the colonic mucosal growth and epithelial proliferation. A reduction in the colonic butyrate level induces chronic mucosal atrophy. Short-chain fatty acid enemas increase mucosal generation, crypt length, and DNA content of the colonocytes. They also ameliorate symptoms of ulcerative colitis in human patients and rats injected with trinitrobenzene sulfonic acid (TNBS). Butyrate, and also to a lesser degree propionate, are substrates for the aerobic energy metabolism, and trophic factors of the colonocytes. Adverse butyrate effects occur in normal and neoplastic colonic cells. In normal cells, butyrate induces proliferation at the crypt base, while inhibiting proliferation at the crypt surface. In neoplastic cells, butyrate inhibits DNA synthesis and arrests cell growth in the G1 phase of the cell cycle. The improvement of the TNBS-induced colonic inflammation occurred earlier in the resistant starch (RS)-fed rats than in the RS-free group. This benefit coincided with activation of colonic epithelial cell proliferation and the subsequent restoration of apoptosis. The noncollagenous basement membrane protein laminin was regenerated initially in the RS-fed group, demonstrating what could be a considered lower damage to the intestinal barrier function. The calculation of intestinal short-chain fatty acid absorption confirmed this conclusion. The uptake of short-chain fatty acids in the colon is strongly inhibited in the RS-free group, but only slightly reduced in the animals fed with RS. Additionally, RS enhanced the growth of intestinal bacteria assumed to promote health. Further studies involving patients suffering from ulcerative colitis are necessary to

    Full Text Available The kudzu root is one of the earliest medicinal plants listed in traditional Chinese medicine. In this paper, chemical compositions changes of kudzu roots from one year old to five years old were analyzed with respect to puerarin, acid-insoluble polysaccharides, acid-soluble polysaccharides, reducing sugar, protein, free amino acids, and lipid. In addition, the puerarin content was determined by high performance liquid chromatography (HPLC method. The results showed that acid-soluble polysaccharides content of kudzu root increased with each growth period. In contrast, the acid-insoluble polysaccharides decreased significantly. The contents of reducing sugar and puerarin in kudzu root decreased significantly during its growth period. Beyond that, the contents of protein, free amino acids, and lipid in kudzu root ranged from 31.8 to 45.8 g/kg, 2.21 to 4.33 g/kg, and 32.2 to 76.9 g/kg, respectively. The trend of protein content coincided with the total content of free amino acids, in contrast to lipid. This paper provides a set of data and the select of kudzu root for the processing and development of new products of kudzu root.

    Kudzu is an exotic vine that threatens the forests of the southern U.S. Five herbicides were tested with regard to their efficacy in controlling kudzu, community recover was monitored, and interactions with planted pines were studied. The sites selected were old farm sites dominated by kudzu.These were burned following herbicide treatment. The herbicides included triclopyr, clopyralid, metsulfuron, tebuthiuron, and picloram plus 2,4-D. Pine seedlings were planted the following year. Regression equations were developed for predicting biomass and leaf area. Four distinct plant communities resulted from the treatments. The untreated check continued to be kudzu dominated. Blackberry dominated the clopyradid treatment. Metsulfron, trychlopyr and picloram treated sites resulted in herbaceous dominated communities. The tebuthiuron treatment maintained all vegetation low.

  13. Organic and Inorganic Dietary Phosphorus and Its Management in Chronic Kidney Disease

    Full Text Available Dietary phosphorus control is often a main strategy in the management of patients with chronic kidney disease. Dietary protein is a major source of phosphorus intake. Recent data indicate that imposed dietary phosphorus restriction may compromise the need for adequate protein intake, leading to protein-energy wasting and possibly to increased mortality. The two main sources of dietary phosphorus are organic, including animal and vegetarian proteins, and inorganic, mostly food preservatives. Animal-based foods and plant are abundant in organic phosphorus. Usually 40% to 60% of animal-based phosphorus is absorbed; this varies by degree of gastrointestinal vitamin-D-receptor activation, whereas plant phosphorus, mostly associated with phytates, is less absorbable by human gastrointestinal tract. Up to 100% of inorganic phosphorus in processed foods may be absorbed; ie, phosphorus in processed cheese and some soda (cola drinks. A recent study suggests that a higher dietary phosphorus-protein intake ratio is associated with incremental death risk in patients on long-term hemodialysis. Hence, for phosphorus management in chronic kidney disease, in addition to absolute dietary phosphorus content, the chemical structure (inorganic versus organic, type (animal versus plant, and phosphorus-protein ratio should be considered. We recommend foods and supplements with no or lowest quantity of inorganic phosphorus additives, more plant-based proteins, and a dietary phosphorus-protein ratio of less than 10 mg/g. Fresh (nonprocessed egg white (phosphorus-protein ratio less than 2 mg/g is a good example of desirable food, which contains a high proportion of essential amino acids with low amounts of fat, cholesterol, and phosphorus.

    Chronic diseases patients often require constant dietary control that involves complicated interaction among factors such as the illness stage, the patient's physical condition, the patient's activity level, the amount of food intake, and key nutrient restrictions. This study aims to integrate multiple knowledge sources for problem solving modeling and knowledge-based system (KBS) development. A chronic kidney disease dietary consultation system is constructed by using Web Ontology Language (OWL) and Semantic Web Rule Language (SWRL) to demonstrate how a KBS approach can achieve sound problem solving modeling and effective knowledge inference. For system evaluation, information from 84 case patients is used to evaluate the performance of the system in recommending appropriate food serving amounts from different food groups for balanced key nutrient ingestion. The results show that, excluding interference factors, the OWL-based KBS can achieve accurate problem solving reasoning while maintaining knowledge base shareability and extensibility. PMID:25451101

    The bean plataspid, Megacopta cribraria (F.), recently was discovered in the United States feeding on kudzu, Pueraria montana Lour. (Merr.) variety lobata (Willd.), an economically important invasive vine. We studied its biology on kudzu and its impact on kudzu growth. We also tested its ability to use other common forest legumes for oviposition and development. Flight intercept traps operated from 17 May 2010 to 31 May 2011 in a kudzu field near Athens, GA showed three peaks of adult flight activity suggesting there are two generations per year on kudzu. Vine samples examined for eggs from April 2010 to April 2011 and June to October 2011 showed two periods of oviposition activity in 2010, which coincided with the peaks in adult activity. In 2011, the second period of oviposition began on or before 24 June and then egg abundance declined gradually thereafter until late August when we recovered Dum. Cours.) G. Don had 122.2 and 108.4 eggs per plant, respectively. Kudzu and soybean were the only species M. cribraria completed development on. Plots protected from M. cribraria feeding by biweekly insecticide applications had 32.8% more kudzu biomass than unprotected plots. Our results show that M. cribraria has a significant impact on kudzu growth and could help suppress this pest weed. PMID:22525058

    Kudzu is an exotic vine that threatens forests in the southeastern United States. It can climb, overtop, and subsequently kill new seedlings or mature trees. Herbicides are commonly used to control kudzu; however, eradication might require retreatment for 3 to 10 yr in young stands and 7 to 10 yr for mature stands. Clopyralid, picloram, triclopyr, metsulfuron, and tebuthiuron exert various degrees of control, depending on soil type, meteorological conditions, herbicide formulation, seasonal application, characteristics of the kudzu stand, and frequency and number of herbicide. Field residue data for soil or leachate are lacking for all of these herbicides when they are used in actual forest regeneration programs in the Coastal Plain. These data are needed to assess the relative potential for the herbicides to leach into groundwater or to move off-site into sensitive ecological areas of the Coastal Plain in which sandy soils predominate and the groundwater tends to be shallow. As part of an integrated pest management program to control kudzu on forest regeneration areas at the Savannah River Site near New Ellenton, SC, five herbicides were evaluated from the standpoints of herbicide leaching, kudzu control, and plant community development. Three herbicide chemical families were represented. This included pyridinecarboxylic acid herbicides (clopyralid, picloram 1 2,4-D, and triclopyr), a sulfonylurea herbicide (metsulfuron), and a substituted urea herbicide (tebuthiuron).

    A possible relationship between Na+ intake and increased prevalence and mortality from asthma and chronic obstructive pulmonary disease (COPD) has been suggested but not clearly proven for several reasons (difficulty in assessing Na+ and K+ both by 24 h excretion and dietary recall, too small an effect of these ions on the pathology, and the role of potential confounders). We wanted to determine the relationship of Na+ and K+ intake, assessed by means of a 7 day recall, with chronic respiratory symptoms and bronchial responsiveness in a sample of the general population. Two hundred and five subjects were studied, with complete dietary and respiratory questionnaires, and baseline respiratory function tests, together with a subsample of 146 subjects who underwent histamine challenge. The 7 day recall consisted of two parts: the first assessed discretionary Na+; and the second assessed Na+ and K+ contained in food. The whole sample was split into two groups based on the levels of consumption, and the statistical analysis was performed contrasting the three lower quartiles vs the highest. Smoking habit, social economic status, age and body mass index (BMI) were not confounders for Na+ and K+ intake. The prevalence of symptomatic subjects and baseline respiratory function values were not significantly different in the two groups of quartiles for Na+ and K+. Baseline respiratory values and dose-response slope of the subsample were also not significantly different. We did not prove a relationship between these dietary factors and either bronchial responsiveness or chronic respiratory symptoms. Although we consider that our questionnaire is more reliable than other methods for Na+ and K+ assessment, several potential biases still remain.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7613539

    Full Text Available The goal of this project was to investigate the effects and possible developmental disease implication of chronic dietary TCDD exposure on global gene expression anchored to histopathologic analysis in juvenile zebrafish by functional genomic, histopathologic and analytic chemistry methods. Specifically, juvenile zebrafish were fed Biodiet starter with TCDD added at 0, 0.1, 1, 10 and 100 ppb, and fish were sampled following 0, 7, 14, 28 and 42 d after initiation of the exposure. TCDD accumulated in a dose- and time-dependent manner and 100 ppb TCDD caused TCDD accumulation in female (15.49 ppb and male (18.04 ppb fish at 28 d post exposure. Dietary TCDD caused multiple lesions in liver, kidney, intestine and ovary of zebrafish and functional dysregulation such as depletion of glycogen in liver, retrobulbar edema, degeneration of nasal neurosensory epithelium, underdevelopment of intestine, and diminution in the fraction of ovarian follicles containing vitellogenic oocytes. Importantly, lesions in nasal epithelium and evidence of endocrine disruption based on alternatively spliced vasa transcripts are two novel and significant results of this study. Microarray gene expression analysis comparing vehicle control to dietary TCDD revealed dysregulated genes involved in pathways associated with cardiac necrosis/cell death, cardiac fibrosis, renal necrosis/cell death and liver necrosis/cell death. These baseline toxicological effects provide evidence for the potential mechanisms of developmental dysfunctions induced by TCDD and vasa as a biomarker for ovarian developmental disruption.

    Full Text Available Abstract Alcoholic neuropathy is most likely result of dietary deficiency rather than direct neurotoxic effect of alcohol. A male alcoholic patient aged 34- years old with clear clinical sign of peripheral neuropathy was examined after his habit of six years chronic alcoholic drinking. Conduction velocities latencies and nerve action potential amplitudes was measured from median radial common peroneal and sural nerves on respective upper and lower limb and the results showed that there was decrease in conduction velocity of common peroneal and posterior tibial in lower limbs. However sensory nerve conduction SNCV of sural nerve right and left was normal in lower limb. Based on the results observed in our study we conclude that the combination of vitamin B12 uridine and cytidine can be safe and effective in the treatment of patients presenting alcoholic polyneuropathy. So the prognosis of alcoholic peripheral neuropathy is good and independent of age provided that intake of alcohol is withdrawn completely.

    Floor pen studies were conducted with 270 broiler chicks and 144 turkey poults, all 1 wk old, to evaluate the chronic effects of fumonisin B1 (FB1). A completely randomized design was used in both studies with six pen replicates of 15 chicks or eight pen replicates of six poults assigned to each of three dietary treatments from Weeks 1 to 7 (broilers) or to Week 14 (turkeys). Fusarium moniliforme (M-1325) culture material was added to a typical corn-soybean basal diet to supply 0, 25, or 50 mg FB1/kg diet. Feed intake, body weight gain, and feed conversion of chicks were not affected (P > 0.05) by FB1. Turkeys fed 50 mg FB1/kg had significantly (P 0.05) by FB1, other than those chicks fed 25 mg FB1/kg, which had lower (P Broilers fed 50 mg FB1/kg had decreased serum calcium and increased serum chloride when compared to broilers fed 0 or 25 mg FB1/kg. Hematology was not affected (P > 0.05) by dietary FB1. No lesions were present in any organ examined microscopically. Results indicate that 50 mg FB1/kg diet is detrimental to turkeys but is not toxic to broilers fed to market age. PMID:11885900

    Chronic wasting disease (CWD), the only known wildlife prion disease, affects deer, elk and moose. The disease is an ongoing and expanding problem in both wild and captive North American cervid populations and is difficult to control in part due to the extreme environmental persistence of prions, which can transmit disease years after initial contamination. The role of exogenous factors in CWD transmission and progression is largely unexplored. In an effort to understand the influence of environmental and dietary constituents on CWD, we collected and analyzed water and soil samples from CWD-negative and positive captive cervid facilities, as well as from wild CWD-endozootic areas. Our analysis revealed that, when compared with CWD-positive sites, CWD-negative sites had a significantly higher concentration of magnesium, and a higher magnesium/copper (Mg/Cu) ratio in the water than that from CWD-positive sites. When cevidized transgenic mice were fed a custom diet devoid of Mg and Cu and drinking water with varied Mg/Cu ratios, we found that higher Mg/Cu ratio resulted in significantly longer survival times after intracerebral CWD inoculation. We also detected reduced levels of inflammatory cytokine gene expression in mice fed a modified diet with a higher Mg/Cu ratio compared to those on a standard rodent diet. These findings indicate a role for dietary Mg and Cu in CWD pathogenesis through modulating inflammation in the brain. PMID:27216881

Catla catla, Labeo rohita and Cirrhina mrigala were exposed to chronic sub-lethal concentrations (1/3rd of LC50/LD50 of waterborne and dietary copper (Cu, cadmium (Cd, zinc (Zn, nickel (Ni and cobalt (Co, separately, in glass aquaria under constant water temperature (29oC, pH (7.5 and hardness (225 mgL-1 for 12 weeks. Waterborne and dietary exposures caused significantly variable accumulation of metals in three fish species that followed Zn>Ni>Cd>Co>Cu. Fish liver showed significantly higher tendency to accumulate Cu (69.64±25.35 µg g-1, Cd (68.93±21.65 µg g-1, Zn (91.46±29.53 µg g-1, Ni (74.64±18.61 µg g-1 and Co (22.65±20.56 µg g-1, followed by that of kidney and gills, with significant differences while muscle and bones exhibited significantly least tendency to accumulate all metals. Labeo rohita (31.63±2.43 µg g-1 and C. mrigala (31.43±13.70 µg g-1 exhibited significantly higher ability to amass metals than that of C. catla (27.96±10.28 µg g-1. Waterborne exposure caused significantly higher accumulation of metals in fish liver (72.69±27.91 µg g-1, followed by that in kidney, gills, skin, muscle, fins and bones with the average concentrations of 45.14±18.70, 39.47±21.13, 30.81±12.64, 22.65±17.34, 22.23±11.74 and 12.14±6.25 µg g-1, respectively. Dietary exposure resulted into significant escalation of metals in fish liver (58.23±32.44 µg g-1 while it was lowest in bones. Waterborne exposure caused significantly higher accumulation of all metals in fish body than that of dietary treatments.

    Full Text Available Objectives: Given the relationship between chronic periodontitis and high levels of oxidative stress, this review aims to clarify what role can played the dietary intake of different antioxidants in maintaining a healthy periodontium and in reducing chronic periodontitis risk, as well as possible use of dietary therapies based on them for this disease treatment. Methods: The database of the National Library of Medicine, Washington, DC (MEDLINE PubMed was used and all the studies in animals and humans are on the subject of interest in English writing online available from inception of the database until May 2015 were collected. Results: Antioxidants analyzed in this regard include vitamin C, vitamin A, carotenoids and some polyphenols, and coenzyme Q; as well as minerals iron, copper and zinc that are constituents of antioxidant enzymes. Still, there is a paucity of studies with few human studies, mostly observational. Among the various antioxidants, vitamin E and polyphenols seem to have more evidence for its beneficial effect, but in general the studies are insufficient to rule out or establish what antioxidants are useful and which are not. Conclusions: Overall, the data presented indicate that dietary antioxidants are beneficial for periodontal health, at least under certain circumstances. However more studies are needed to establish the relationship between chronic periodontitis and each specific antioxidant and to design useful dietary interventions for this disease management.

  7. Chronic dietary toxicity and carcinogenicity study with potassium perfluorooctanesulfonate in Sprague Dawley rats

    International Nuclear Information System (INIS)

    Highlights: ► A two-year dietary toxicity and cancer bioassay was conducted with K+PFOS in rats. ► Hepatocellular hypertrophy was the main microscopic non-neoplastic finding. ► Hepatocellular adenoma was increased in males and females fed the high dose. ► Males fed high dose for 1 year had increased thyroid follicular cell adenoma. ► The latter finding is of equivocal relationship to treatment. -- Abstract: To investigate toxicity and neoplastic potential from chronic exposure to perfluorooctanesulfonate (PFOS), a two-year toxicity and cancer bioassay was conducted with potassium PFOS (K+PFOS) in male and female Sprague Dawley rats via dietary exposure at nominal K+PFOS concentrations of 0, 0.5, 2, 5, and 20 μg/g (ppm) diet for up to 104 weeks. Additional groups were fed 20 ppm for the first 52 weeks, after which they were fed control diet through study termination (20 ppm Recovery groups). Scheduled interim sacrifices occurred on Weeks 4, 14, and 53, with terminal sacrifice between Weeks 103 and 106. K+PFOS appeared to be well-tolerated, with some reductions in body weight occurring in treated rats relative to controls over certain study periods. Male rats experienced a statistically significant decreased trend in mortality with significantly increased survival to term at the two highest treatment levels. Decreased serum total cholesterol, especially in males, and increased serum urea nitrogen were consistent clinical chemistry observations that were clearly related to treatment. The principal non-neoplastic effect associated with K+PFOS exposure was in livers of males and females and included hepatocellular hypertrophy, with proliferation of endoplasmic reticulum, vacuolation, and increased eosinophilic granulation of the cytoplasm. Statistically significant increases in hepatocellular adenoma were observed in males (p = 0.046) and females (p = 0.039) of the 20 ppm treatment group, and all of these tumors were observed in rats surviving to terminal

    Full Text Available Abstract Background Adoption of a healthy diet has been identified as the cornerstone in the prevention and management of chronic diseases. However, non-adherence to lifestyle changes raises an important issue since adherence level to dietary advice is a key determinant of the effectiveness of dietary treatment. Therefore, based on the results of a Cochrane systematic review on interventions for enhancing adherence to dietary advice for preventing and managing chronic diseases in adults, the aim of this study is to assess the importance and applicability of interventions enhancing adherence to dietary advice in the Canadian context. Methods/Design In phase 1, dietitians' opinion will be assessed through a Delphi study regarding the importance and the applicability in the Canadian context of the interventions found the most effective to enhance adherence to dietary advice through a Cochrane systematic review. In phase 2, findings of the Cochrane systematic review assessing the effects of interventions for enhancing adherence to dietary advice will be reported in a practical format on an online knowledge translation tool for dietitians and other health professionals. Discussion In recent years, there has been an increasing recognition of the failure to translate research findings into clinical practice. Therefore, knowledge translation efforts need to prioritize effective interventions that will be the most relevant for practice and end-users by adapting them to the local context. Our study will provide decision makers in the field of dietetic practice with essential knowledge on adherence for elaborating educational activities for academic or professional settings that will respond to dietitians' priorities in terms of importance and applicability to day-to-day practice.

    While acute treatment with beetroot juice (BRJ) containing nitrate (NO3 (-)) can lower systolic blood pressure (SBP), afterload, and myocardial O2 demand during submaximal exercise, effects of chronic supplementation with BRJ (containing a relatively low dose of NO3 (-), 400 mg) on cardiac output (CO), SBP, total peripheral resistance (TPR), and the work of the heart in response to dynamic exercise are not known. Thus, in 14 healthy males (22 ± 1 yr), we compared effects of 15 days of both BRJ and nitrate-depleted beetroot juice (NDBRJ) supplementation on plasma concentrations of NOx (NO3 (-)/NO2 (-)), SBP, diastolic blood pressure (DBP), mean arterial pressure (MAP), CO, TPR, and rate pressure product (RPP) at rest and during progressive cycling exercise. Endothelial function was also assessed via flow-mediated dilation (FMD). BRJ supplementation increased plasma NOx from 83.8 ± 13.8 to 167.6 ± 13.2 μM. Compared with NDBRJ, BRJ reduced SBP, DBP, MAP, and TPR at rest and during exercise (P < 0.05). In addition, RPP was decreased during exercise, while CO was increased, but only at rest and the 30% workload (P < 0.05). BRJ enhanced FMD-induced increases in brachial artery diameter (pre: 12.3 ± 1.6%; post: 17.8 ± 1.9%). We conclude that 1) chronic supplementation with BRJ lowers blood pressure and vascular resistance at rest and during exercise and attenuates RPP during exercise and 2) these effects may be due, in part, to enhanced endothelium-induced vasodilation in contracting skeletal muscle. Findings suggest that BRJ can act as a dietary nutraceutical capable of enhancing O2 delivery and reducing work of the heart, such that exercise can be performed at a given workload for a longer period of time before the onset of fatigue.

  12. Gene expression and pathologic alterations in juvenile rainbow trout due to chronic dietary TCDD exposure

    International Nuclear Information System (INIS)

    Highlights: •First report of the effects of dietary TCDD in juvenile trout smaller than 20 g. •TCDD uptake was estimated using published models and confirmed by GC. •First report of dietary TCDD-induced lesions in nasal epithelium in any species. •Several useful biomarkers are identified from microarray-based transcriptomics analysis. -- Abstract: The goal of this project was to use functional genomic methods to identify molecular biomarkers as indicators of the impact of TCDD exposure in rainbow trout. Specifically, we investigated the effects of chronic dietary TCDD exposure on whole juvenile rainbow trout global gene expression associated with histopathological analysis. Juvenile rainbow trout were fed Biodiet starter with TCDD added at 0, 0.1, 1, 10 and 100 ppb (ng TCDD/g food), and fish were sampled from each group at 7, 14, 28 and 42 days after initiation of feeding. 100 ppb TCDD caused 100% mortality at 39 days. Fish fed with 100 ppb TCDD food had TCDD accumulation of 47.37 ppb (ng TCDD/g fish) in whole fish at 28 days. Histological analysis from TCDD-treated trout sampled from 28 and 42 days revealed that obvious lesions were found in skin, oropharynx, liver, gas bladder, intestine, pancreas, nose and kidney. In addition, TCDD caused anemia in peripheral blood, decreases in abdominal fat, increases of remodeling of fin rays, edema in pericardium and retrobulbar hemorrhage in the 100 ppb TCDD-treated rainbow trout compared to the control group at 28 days. Dose- and time-dependent global gene expression analyses were performed using the cGRASP 16,000 (16K) cDNA microarray. TCDD-responsive whole body transcripts identified in the microarray experiments have putative functions involved in various biological processes including growth, cell proliferation, metabolic process, and immune system processes. Nine microarray-identified genes were selected for QPCR validation. CYP1A3 and CYP1A1 were common up-regulated genes and HBB1 was a common down

    , abundances of transcripts of cytochrome P450 side-chain cleavage (p450scc) and cytochrome P450 11B1 (cyp11b1) were not significantly different between controls and Se-Met exposed trout. Exposure to Se-Met affected accumulation and tissue partitioning of glycogen and triglycerides in liver and muscle as concentrations of these energy reserves were greater in muscle, but not liver. Concentrations of glycogen and triglycerides in muscle, but not in liver, were lesser following the handling stressor suggesting that the muscle energy reserves are an important source of energy required for recovery from the handling stressor. The results of the study demonstrate that chronic exposure to dietary Se-Met elicits a stress response, but prevents a cortisol response to a secondary handling stressor, most likely due to cortisol inactivation. Moreover, exposure to Se-Met has effects on concentrations of energy reserves that are important for providing the energy necessary to cope with a secondary stressor.

    Full Text Available Abstract Background Infection with HIV-1 results in marked immunologic insults and structural damage to the intestinal mucosa, including compromised barrier function. While the development of highly active antiretroviral therapy (HAART has been a major advancement in the treatment of HIV-1 infection, the need for novel complementary interventions to help restore intestinal structural and functional integrity remains unmet. Known properties of pre-, pro-, and synbiotics suggest that they may be useful tools in achieving this goal. Methods This was a 4-week parallel, placebo-controlled, randomized pilot trial in HIV-infected women on antiretroviral therapy. A synbiotic formulation (Synbiotic 2000® containing 4 strains of probiotic bacteria (1010 each plus 4 nondigestible, fermentable dietary fibers (2.5 g each was provided each day, versus a fiber-only placebo formulation. The primary outcome was bacterial translocation. Secondary outcomes included the levels of supplemented bacteria in stool, the activation phenotype of peripheral T-cells and monocytes, and plasma levels of C-reactive protein and soluble CD14. Results Microbial translocation, as measured by plasma bacterial 16S ribosomal DNA concentration, was not altered by synbiotic treatment. In contrast, the synbiotic formulation resulted in significantly elevated levels of supplemented probiotic bacterial strains in stool, including L. plantarum and P. pentosaceus, with the colonization of these two species being positively correlated with each other. T-cell activation phenotype of peripheral blood lymphocytes showed modest changes in response to synbiotic exposure, with HLA-DR expression slightly elevated on a minor population of CD4+ T-cells which lack expression of HLA-DR or PD-1. In addition, CD38 expression on CD8+ T-cells was slightly lower in the fiber-only group. Plasma levels of soluble CD14 and C-reactive protein were unaffected by synbiotic treatment in this study.

    Full Text Available Background: Changes in lifestyle, especially in different aspects of nutrition and physical activity, have been associated with change in the patterns of diseases, from contagious diseases to non-communicable diseases, and with the prevalence of chronic diseases. Accordingly, this study is carried out within the framework of National Plan to Care for Risk Factors of Non-communicable Diseases with the aim of comparing the dietary patterns and physical activity of people under study in Fars province during 2006-2007. Materials and Methods: Using the WHO Step-by-step Evaluation Model for Risky Factors, the present study determined fifty 20-person clusters, totally 1,000 people within the age group of 15-64 for each year as the research population. After identifying the applicable people, they were visited at their homes and the questionnaires were filled out for them. The necessary analysis was carried out using Version 6 of EPI-info and Version 10 of STATA software.Results: The findings of the present study indicated that men have more intense physical activity than women (p=0.001. The results also indicated a significant increase in consumption of fruit (p=0.01, vegetable (p=0.001, and fish (p=0.001 in 2007 as compared with 2006. The average number of the consumed vegetable units in women was higher than that of men (p=0.01.Conclusion: The findings of this study indicated that the average number of daily consumed units of fruit and vegetable as well as the frequencies of fish consumption per week was lower than the recommended amounts.

    Transient hypothyroidism induced by propyl-2-thiouracyl blocks postpartum Leydig cell development. In the present study, the effects of chronic hypothyroidism on the formation of this adult-type Leydig cell population were investigated, using a more physiological approach. Before mating, dams were put on a diet consisting of an iodide-poor feed supplemented with a low dose of perchlorate and, with their offspring, were kept on this diet until death. In the pups at day 12 postpartum, plasma thyroid-stimulating hormone levels were increased by 20-fold, whereas thyroxine and free tri-iodothyronine levels were severely depressed, confirming a hypothyroid condition. Adult-type progenitor Leydig cell formation and proliferation were reduced by 40-60% on days 16 and 28 postpartum. This was followed by increased Leydig cell proliferation at later ages, suggesting a possible slower developmental onset of the adult-type Leydig cell population under hypothyroid conditions. Testosterone levels were increased 2- to 10-fold in the hypothyroid animals between days 21 and 42 postpartum compared with the age-matched controls. Combined with the decreased presence of 5alpha-reductase, this implicates a lower production capacity of 5alpha-reduced androgens. In 84-day-old rats, after correction for body weight-to-testis weight ratio, plasma insulin-like factor-3 levels were 35% lower in the hypothyroid animals, suggestive of a reduced Leydig cell population. This is confirmed by a 37% reduction in the Sertoli cell-to-Leydig cell ratio in hypothyroid rats. In conclusion, we show that dietary-induced hypothyroidism delays but, unlike propyl-2-thiouracyl, does not block the development of the adult-type Leydig cell population. PMID:19033542

  19. Considerations when using longitudinal cohort studies to assess dietary exposure to inorganic arsenic and chronic health outcomes.

    2016-07-01

    Dietary arsenic exposure and chronic health outcomes are of interest, due in part to increased awareness and data available on inorganic arsenic levels in some foods. Recent concerns regarding levels of inorganic arsenic, the primary form of arsenic of human health concern, in foods are based on extrapolation from adverse health effects observed at high levels of inorganic arsenic exposure; the potential for the occurrence of these health effects from lower levels of dietary inorganic arsenic exposure has not been established. In this review, longitudinal cohort studies are evaluated for their utility in estimating dietary inorganic arsenic exposure and quantifying statistically reliable associations with health outcomes. The primary limiting factor in longitudinal studies is incomplete data on inorganic arsenic levels in foods combined with the aggregation of consumption of foods with varying arsenic levels into a single category, resulting in exposure misclassification. Longitudinal cohort studies could provide some evidence to evaluate associations of dietary patterns related to inorganic arsenic exposure with risk of arsenic-related diseases. However, currently available data from longitudinal cohort studies limit causal analyses regarding the association between inorganic arsenic exposure and health outcomes. Any conclusions should therefore be viewed with knowledge of the analytical and methodological limitations. PMID:27155067

    Full Text Available Functional foods provide health benefit beyond basic nutrition. Functional foods fortified with plant ingredients are well known. Ayurveda (Indian System of Medicine has found several ways in which the medicinal benefits of herbs can be conveyed via certain foods as carriers. Milk is one such carrier which has been effectively used to deliver phytochemicals for targeted health benefits. Indian Kudzu or Pueraria tuberosa Linn. (Fabaceae is an important medicinal plant of Ayurveda, and experiments suggest that it enhances the health benefits of milk when taken with milk as a carrier. Different milk combinations with P. tuberosa were prepared by homogenizing pasteurized toned milk with its ethanolic and hot water extracts and their stability with reference to pH and coagulation was studied over a period of 15 days. The combinations were also analyzed for puerarin, the major isoflavone C-glucoside present in P. tuberosa, through high-performance liquid chromatography using photo diode array detector. It was observed that there was no precipitate formation and the pH also did not change during the study period indicating their physical stability under the experimental conditions. Also there was no significant change in the content of puerarin during the study period, thereby indicating the chemical stability of the samples. These studies will be useful for developing milk nutraceuticals fortified with Indian Kudzu which has the potential to be included as an ingredient in health and functional foods.

    Full Text Available This study was carried out to evaluate the productivity and utilization efficiency of a mixed marandugrass (Brachiaria brizantha cv. Marandu, forage peanut (Arachis pintoi cv. Mandobi and tropical kudzu (Pueraria phaseoloides pasture, rotationally stocked at four daily forage allowance levels (6.6, 10.3, 14.3 and 17.9% of live weight, in order to define sward management targets for these mixtures. In each stocking cycle, dry matter (DM accumulation rates, defoliation intensity (%, grazing depth (% and grazed horizon (cm were evaluated. Sward targets were defined according to the sward condition that best conciliated the grass-legume balance and the equilibrium between forage production and utilization. Pastures submitted to higher forage allowance levels showed higher productivity, but were less efficiently utilized. It was not possible to establish sward management targets for marandugrass-tropical kudzu pastures. For marandugrass-forage peanut pastures the best sward state was set with forage allowance of 10.3% of live weight. Under rotational stocking, the following sward targets were suggested for these pastures in the Western Amazon: pre-grazing height of 30-35 cm (June to September or 45-50 cm (October to May and post-grazing sward height of 20-25 cm (June to September or 25-30 cm (October to May.

  2. Water stress, temperature, and light effects on the capacity for isoprene emission and photosynthesis of kudzu leaves

    International Nuclear Information System (INIS)

    Kudzu (Pueraria lobata (Willd) Ohwi.) is a vine which forms large, monospecific stands in disturbed areas of the southeastern United States. Kudzu also emits isoprene, a hydrocarbon which can significantly affect atmospheric chemistry including reactions leading to tropospheric ozone. Study of physiological aspects of isoprene emission from kudzu so the ecological consequences of isoprene emission can be better understood. Examinations: (a) the development of isoprene emission as leaves developed, (b) the interaction between photon flux density and temperature effects on isoprene emission, (c) isoprene emission during and after water stress, and (d) the induction of isoprene emission from leaves grown at low temperature by water stress or elevated temperature. Isoprene emission under standard conditions of 1000 micromol photons/m(2)/s and 30 degrees C developed only after the leaf had reached full expansion, and was not complete until up to two weeks past the point of full expansion of the leaf. The effect of temperature on isoprene emission was much greater than found for other species, with a 100 degrees C increase in temperature causing an eight-fold increase in the rate of isoprene emission. Isoprene emission from kudzu was stimulated by increases in photon flux density up to 3000 micromol photons/m(2)/s

    Full Text Available This study was carried out to evaluate the dynamics of sward condition and botanical composition of a mixed pasture of marandugrass (Brachiaria brizantha cv. Marandu, forage peanut (Arachis pintoi cv. Mandobi and tropical kudzu (Pueraria phaseoloides, rotationally stocked at four daily forage allowance levels (6.6, 10.3, 14.3 and 17.9% of live weight. Sward condition was characterized in each stocking cycle by measuring pre- and post-grazing sward height, forage mass and percentage of bare ground. Botanical composition (grass, forage peanut, tropical kudzu and weeds was evaluated before each stocking period. Swards under smaller forage allowances presented lower height, forage mass and ground cover. This condition favored the growth of forage peanut, which constituted 21.1, 15.2, 8.4 and 3.8% of forage mass in the last quarter of the experimental period, from the lowest to the highest forage allowance, respectively. Tropical kudzu was sensitive to all forage allowance levels and its percentage in the botanical composition was strongly reduced along the experimental period, especially during the dry season (July to September. Forage peanut cv. Mandobi and marandugrass form a more balanced mixture when pre-grazing sward height is maintained shorter than 45 cm. Tropical kudzu is intolerant to intensive grazing management systems when associated to marandugrass.

    The aim of this cross-sectional study was to investigate whether under-reporting of energy intake affects derived dietary patterns and the association between dietary patterns and self-reported chronic disease. Diets of 6204 women aged 50-69 years participating in the Norwegian Breast Cancer Screening Program were assessed using a 253-item FFQ. We identified dietary patterns using principal component analysis. According to the revised Goldberg cut-off method, women with a ratio of reported energy intake:estimated BMR<1·10 were classified as low energy reporters (n 1133, 18 %). We examined the associations between dietary patterns and self-reported chronic diseases by log-binomial regression, and the results are presented as prevalence ratios (PR) and CI. 'Prudent', 'Western' and 'Continental' dietary patterns were identified among all reporters and plausible reporters. The PR expressing the associations between the 'Western' and 'Prudent' dietary pattern scores and self-reported chronic diseases were consistently highest among plausible reporters except for joint/muscle/skeletal disorders. The largest difference in PR among plausible v. all reporters was found for the association between the 'Prudent' pattern and diabetes (PR for highest v. lowest tertile: PRall reporters 2·16; 95 % CI 1·50, 3·13; P trend<0·001; PRplausible reporters 2·86; 95 % CI 1·81, 4·51; P trend<0·001). In conclusion, our results suggest that under-reporting can result in systematic error that can affect the association between dietary pattern and disease. In studies of dietary patterns, investigators ought to consider reporting effect estimates both for all individuals and for plausible reporters. PMID:27265399

    Estimating dietary sodium intake is a key component of dietary assessment in the clinical setting of HF to effectively implement appropriate dietary interventions for sodium reduction and monitor adherence to the dietary treatment. In a research setting, assessment of sodium intake is crucial to an essential methodology to evaluate outcomes after a dietary or behavioral intervention. Current available sodium intake assessment methods include 24-hour urine collection, spot urine collections, multiple day food records, food recalls, and food frequency questionnaires. However, these methods have inherent limitations that make assessment of sodium intake challenging, and the utility of traditional methods may be questionable for estimating sodium intake in patients with HF. Thus, there are remaining questions about how to best assess dietary sodium intake in this patient population, and there is a need to identify a reliable method to assess and monitor sodium intake in the research and clinical setting of HF. This paper provides a comprehensive review of the current methods for sodium intake assessment, addresses the challenges for its accurate evaluation, and highlights the relevance of applying the highest-quality measurement methods in the research setting to minimize the risk of biased data.

    Chromium (Cr) is an essential metal and a nutritional supplement for both human and agricultural uses. It is also a pollutant from a variety of industrial uses. These uses can lead to elevated Cr levels in aquatic environments, where it can enter and affect aquatic organisms. Its accumulation and subsequent effects in fish have received relatively little attention, especially for chronic exposure. In the present study, Japanese medaka were chronically exposed to dissolved or dietary Cr(VI) for 3 months. Cr accumulation in liver, gills, intestine, and brain was evaluated. Effects on the antioxidant system, nervous system (acetylcholinesterase, AChE), digestive system (α-glucosidase, α-Glu), and tissue histology (liver and gills) were also assessed. Cr accumulation was observed in the intestine and liver of fish exposed to Cr-contaminated brine shrimp. However, chronic dissolved Cr exposure led to significant Cr accumulation in all organs tested. Analysis of the subcellular distribution of Cr in medaka livers revealed that 37% of the Cr was present in the heat stable protein fraction. The dissolved Cr exposure had pronounced effects on the antioxidant system in the liver, with an elevated ratio of reduced glutathione/oxidized glutathione (GSH/GSSG) and decreases in GSH and glutathione S-transferase (GST). The α-Glu activity in the intestine was significantly inhibited. In addition, Cr exposure caused histopathological alterations in the gills and liver. In general, the effects of dietary Cr were relatively minor, possible due to the much lower accumulation in the fish. Our results imply that Japanese medaka accumulate Cr mainly via uptake of dissolved Cr(VI). PMID:27162070

    Selenomethionine (Se-Met) is the major dietary form of selenium (Se). Detrimental effects have been associated with exposure to elevated dietary selenium. Previous studies have demonstrated effects of Se on the endocrine system, in particular effects on cortisol and thyroid hormones. However, no information is available regarding effects of Se on sex steroid hormones. In the present study, effects of dietary exposure to an environmentally relevant concentration (4.54 mg/kg wet weight (ww)) of Se-Met for 126 days on concentrations of sex steroid hormones in blood plasma of female rainbow trout were determined. Furthermore, the molecular basis for effects of Se-Met on plasma sex steroid hormone concentrations was investigated. Concentrations of androstenedione (A), estrone (E1), and estradiol (E2) were 39.5-, 3.8-, and 12.7-fold greater in plasma of treated females than the untreated controls, respectively. Testosterone (T) was detected only in plasma of treated females. The greater E2 concentration stimulated greater transcript abundance of vitellogenin (vtg) and zona-radiata protein (zrp). Female rainbow trout exposed to Se-Met had greater transcript abundance of key steroidogenic proteins and enzymes, including peripheral benzodiazepine receptor (pbr), cytochrome P450 side-chain cleavage (P450scc), and 3{beta}-hydroxysteroid dehydrogenase (3{beta}-hsd). Exposure to Se-Met did not affect transcript abundance of luteinizing hormone (lh) or follicle stimulating hormone (fsh). Similarly, there was no change in transcript abundance of luteinizing hormone receptor (lhr) or follicle stimulating hormone receptor (fshr). Long-term exposure to dietary Se-Met has the potential to stimulate vitellogenesis in female rainbow trout by directly stimulating ovarian tissue steroidogenesis. This is the first study to report effects of Se on sex steroid hormone production in fish.

  11. Dietary phosphorus excess: a risk factor in chronic bone, kidney, and cardiovascular disease?

    Science.gov (United States)

    Uribarri, Jaime; Calvo, Mona S

    2013-01-01

    There is growing evidence in the nephrology literature supporting the deleterious health effect of excess dietary phosphorus intake. This issue has largely escaped the attention of nutrition experts until this symposium, which raised the question of whether the same health concerns should be extended to the general population. The potential hazard of a high phosphorus intake in the healthy population is illustrated by findings from acute and epidemiologic studies. Acute studies in healthy young adults demonstrate that phosphorus intakes in excess of nutrient needs may significantly disrupt the hormonal regulation of phosphorus contributing to disordered mineral metabolism, vascular calcification, bone loss, and impaired kidney function. One of the hormonal factors acutely affected by dietary phosphorus loading is fibroblast growth factor-23, which may be a key factor responsible for many of the cardiovascular disease (CVD) complications of high phosphorus intake. Increasingly, large epidemiological studies suggest that mild elevations of serum phosphorus within the normal range are associated with CVD risk in healthy populations. Few population studies link high dietary phosphorus intake to mild changes in serum phosphorus due to study design issues specific to phosphorus and inaccurate nutrient composition databases. The increasing phosphorus intake due to the use of phosphorus-containing ingredients in processed food and the growing consumption of processed convenience and fast foods is an important factor that needs to be emphasized.

    Little is known about the propensity of crocodilians to bioaccumulate trace elements as a result of chronic dietary exposure. We exposed 36 juvenile alligators (Alligator mississippiensis) to one of four dietary treatments that varied in the relative frequency of meals containing prey from coal combustion waste (CCW)-contaminated habitats vs. prey from uncontaminated sites, and evaluated tissue residues and growth rates after 12 mo and 25 mo of exposure. Hepatic and renal concentrations of arsenic (As), cadmium (Cd) and selenium (Se) varied significantly among dietary treatment groups in a dose-dependent manner and were higher in kidneys than in livers. Exposure period did not affect Se or As levels but Cd levels were significantly higher after 25 mo than 12 mo of exposure. Kidney As and Se levels were negatively correlated with body size but neither growth rates nor body condition varied significantly among dietary treatment groups. Our study is among the first to experimentally examine bioaccumulation of trace element contaminants in crocodilians as a result of chronic dietary exposure. A combination of field surveys and laboratory experiments will be required to understand the effects of different exposure scenarios on tissue residues, and ultimately link these concentrations with effects on individual health.

    Non-communicable diseases with dietary implications, ischaemic heart disease, diabetes mellitus and cancers of the breast and colon are discussed in relation to their prevalence and mortality rates in peninsular Malaysia during the past few decades. The mortality rate due to diseases of the circulatory system has more than doubled since 1970, deaths due to ischaemic heart disease being the major cause. The prevalence of diabetes mellitus has risen from 0.65% in 1960 to about 4% currently. The mortality risk for both ischaemic heart disease and diabetes is highest in the Indian compared to Malay and Chinese populations. The Chinese show the highest mortality rate for cancers of the breast and colon. This could reflect, partly, because more people especially in the urban areas are seeking treatment and improved diagnosis. Empirical dietary data indicate an increase in the prevalence of hypercholesterolaemia among urban adults and overweight among urban and rural adults. Aggregate data from food balance sheets indicate increased availability of energy intake from fats and oils, sugar, and animal products, with concomitant decline in available energy from plant products. Continued public health education on the important linkage between diet and disease is called for. PMID:24323170

  16. Does chronic glycolysis accelerate aging? Could this explain how dietary restriction works?

    Science.gov (United States)

    Hipkiss, Alan R

    2006-05-01

    The mechanisms by which dietary restriction (DR) suppresses aging are not understood. Suppression of glycolysis by DR could contribute to controlling senescence. Many glycolytic intermediates can glycate proteins and other macromolecules. Methyglyoxal (MG), formed from dihydroxyacetone- and glyceraldehyde-3-phosphates, rapidly glycates proteins, damages mitochondria, and induces a prooxidant state to create a senescent-like condition. Ad libitum-fed and DR animals differ in mitochondrial activity and glycolytic flux rates. Persistent glycolysis in the unrestricted condition would increase the intracellular load of glycating agents (e.g., MG) and increase ROS generation by inactive mitochondria. Occasional glycolysis during DR would decrease MG and reactive oxygen species (ROS) production and could be hormetic, inducing synthesis of glyoxalase-1 and anti-glycating agents (carnosine and polyamines).

    Changes in metabolic state alter foraging behavior and food preference in animals. Here, I show that normally attractive food becomes repulsive to Caenorhabditis elegans if animals are chronically undernourished as a result of alimentary tract defects. This behavioral plasticity is achieved in two ways: increased food leaving and induction of aversive behavior towards food. A particularly strong food avoider is defective in the chitin synthase that makes the pharyngeal lining. Food avoidance ...

    Dietary exposure to pesticide residues may present a risk to public health, especially for sensitive populations such as pregnant women. To characterize this risk, this study assessed chronic dietary exposure to pesticide residues based on the French ELFE cohort. A self-administered food frequency questionnaire (FFQ) about the last three months of pregnancy filled in by pregnant women in 2011 was used in combination with occurrence data from French Total Diet Studies completed by the results of national monitoring programs on pesticide residues in food. The dietary intake of pesticides (μg/kg of body weight/day) was estimated for 14,099 pregnant women with a complete FFQ, for 317 substances under two occurrence scenarios to handle left-censored data: a lower-bound scenario (LB), where undetected results were set to zero, and an upper-bound scenario (UB), where undetected results were set to the detection limit if the substance was expected to be found in food and zero if it was not. The risk was assessed for 284 substances with a toxicological reference value (TRV) and a good coverage level of the diet potentially contributing to pesticide intake. The cumulative risk was also assessed for seven effects on nervous and thyroid systems using the hazard index and the Cumulative Assessment Groups defined by EFSA. Substances with the highest exposure levels under the LB scenario were, in decreasing order, imazalil, piperonyl butoxide, chlorpropham, thiabendazole, iprodione and propargite. Under the LB scenario, only for lindane did women have a statistically significant probability of exceeding the TRV (2.4%). Under the UB scenario, risk could not be excluded for nine other substances. A better management of left-censored data and more sensitive analyses of the main food contributors might help to refine the UB exposure and risk assessments. A statistically significant cumulative risk was found for neurochemical effects related to high intake levels of three

    Although interest in using probiotics to prevent and treat intestinal diseases is increasing, the effects of specific probiotic strains still remain unclear. Here, we assess the therapeutic effects of two probiotic strains, Lactobacillus rhamnosus NutRes 1 and Bifidobacterium breve NutRes 204 on a dextran sodium sulphate (DSS)-induced chronic murine colitis model. The chronic colitis was induced by two DSS treatment cycles with a rest period of 10 days (the remission or resolution phase). The probiotic supplementation was started during the resolution phase, after the first DSS treatment cycle, and continued until the end of the experiment. In addition to clinical observations made during the experiment, cellular infiltration was measured along with mRNA expression of pro-inflammatory cytokines, T cell-associated cytokines, and Toll like receptors (TLR) in the inflamed colon after second DSS treatment cycle. L. rhamnosus, but not B. breve, rapidly and effectively improved the DSS-induced bloody diarrhoea during the resolution phase. However, a contradictory effect by both probiotic strains on the faecal condition was found after re-induction of colitis. The worsening of the faecal condition was accompanied by a reduced number of neutrophils and increased expression of interferon-γ in the colons of DSS-treated mice. Furthermore, an increased expression of TLR2, TLR6 and pro-inflammatory markers including chemokine (C-C motif) ligand 2, interleukin (IL)-1β, tumour necrosis factor α and IL-6 was found in DSS-treated mice with L. rhamnosus supplementation. These results indicate that therapeutic administration of specific probiotics might be beneficial during the resolution phase of colitis. However, caution should be taken as specific probiotic treatments reduce neutrophil influx, which may be the reason of exacerbation of chronic colitis. PMID:26645352

    Brain food, e.g. L-tryptophan, antioxidative substances, B vitamins and magnesium are thought to be beneficial for obesity, inflammation and insulin resistance. In the present pilot study we hypothesised that a specific amino acid mixture with micronutrients improves the cardiometabolic situation of chronically stressed persons. Cardiovascular and metabolic parameters were analysed as per protocol in 32 patients. Chronic stress disorders in the same patients were assessed by a psychological neurological questionnaire (PNF). After dietary intervention a reduction of the fasting serum insulin concentrations occurred in the treatment group. An association was found between PNF values, insulin concentrations at baseline and an insulin reduction after 12 weeks. The results support the use of our specific dietary supplement for improved stress management and a decrease in metabolic dysfunction. PMID:26878772

    The endemic of chronic renal failure (CRF) emerged in 2002 in the farming provinces of Sri Lanka. An estimate of dietary cadmium intake was between 15 and 28 microg/kg body weight per week. The mean urinary cadmium in patients diagnosed with stage 5 kidney failure was 7.6 microg/g creatinine and 11.6 microg/g for asymptomatic persons. The agrochemical triple superphosphate (TSP) fertilizer containing 23.5-71.7 mg Cd/kg was the source of cadmium added to soils. Mean Cd content in cultivated vs. uncultivated soils in Anuradhapura district was 0.02 +/- 0.01 vs. 0.11 +/- 0.19 mg/kg while in Polonnaruwa district, it was 0.005 +/- 0.004 vs. 0.016 +/- 0.005 mg/kg. Prior to the Green Revolution, the amount of fertilizer used in rice cultivation in 1970 was 32,000 metric tons (Mts) rising to 74,000 Mts in 1975. Up to 68.9 Mts of Cd could have entered into the rice-cascade reservoir environment from TSP use since 1973. Diversion of the Mahaweli River in 1970-1980 further increased cadmium input. Cadmium transfer from Upper Mahaweli water to Polgolla was 72.13 kg/day. Cadmium content of the sediments from reservoirs collecting cadmium from irrigated TSP fertilized crop fields (rice and vegetables) was 1.8-2.4 mg/kg. PMID:20430069

    Multiple pathways including oxidative stress and mitochondrial damage are implicated in neurodegeneration during Parkinson's disease (PD). The current PD drugs provide only symptomatic relief and have limitations in terms of adverse effects and inability to prevent neurodegeneration. Therefore, there is a demand for novel compound(s)/products that could target multiple pathways and protect the dying midbrain dopaminergic neurons, with potential utility as adjunctive therapy along with conventional drugs. Turmeric is a spice used in traditional Indian cuisine and medicine with antioxidant, anti-inflammatory and potential neuroprotective properties. To explore the neuroprotective property of turmeric in PD, mice were subjected to dietary supplementation with aqueous suspensions of turmeric for 3 months, mimicking its chronic consumption and challenged in vivo with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Brain samples from untreated and treated groups were characterised based on mitochondrial complex I (CI) activity, protein nitration and tyrosine hydroxylase immunoreactivity. Chronic turmeric supplementation induced the enzyme activity of γ-glutamyl cysteine ligase, which in turn increased glutathione levels and protected against peroxynitrite-mediated inhibition of brain CI. These mice were also protected against MPTP-mediated protein nitration, CI inhibition and degeneration of substantia nigra neurons in the brain. We conclude that chronic dietary consumption of turmeric protects the brain against neurotoxic insults, with potential application in neurodegeneration. Further characterisation of the active constituents of turmeric that potentially promote neuroprotection could improve the utility of dietary turmeric in brain function and disease. PMID:21473798

    High phosphate intake is known to aggravate renal osteodystrophy along various pathogenetic pathways. Recent studies have raised the possibility that dysregulation of the osteocyte Wnt/β-catenin signaling pathway is also involved in chronic kidney disease (CKD)-related bone disease. We investigated the role of dietary phosphate and its possible interaction with this pathway in an experimental model of adynamic bone disease (ABD) in association with CKD and hypoparathyroidism. Partial nephrectomy (Nx) and total parathyroidectomy (PTx) were performed in male Wistar rats. Control rats with normal kidney and parathyroid function underwent sham operations. Rats were divided into three groups and underwent pair-feeding for 8 weeks with diets containing either 0.6% or 1.2% phosphate: sham 0.6%, Nx+PTx 0.6%, and Nx+PTx 1.2%. In the two Nx+PTx groups, serum creatinine increased and blood ionized calcium decreased compared with sham control group. They also presented hyperphosphatemia and reduced serum parathyroid hormone (PTH) and fibroblast growth factor 23 (FGF23) levels. Fractional urinary excretion of phosphate increased in Nx+PTx 1.2% rats despite lower PTH and FGF23 levels than in sham group. These biochemical changes were accompanied by a decrease in bone formation rates. The Nx+PTx 1.2% group had lower bone volume (BV/TV), higher osteoblast and osteocyte apoptosis, and higher SOST and Dickkopf-1 gene expression than the Nx+PTx 0.6% group. Nx+PTx 0.6% rat had very low serum sclerostin levels, and Nx+PTx 1.2% had intermediate sclerostin levels compared with sham group. Finally, there was a negative correlation between BV/TV and serum sclerostin. These results suggest that high dietary phosphate intake decreases bone volume in an experimental model of CKD-ABD, possibly via changes in SOST expression through a PTH-independent mechanism. These findings could have relevance for the clinical setting of CKD-ABD in patients who low turnover bone disease might be attenuated

The Nx+PTx 1.2% group had lower bone volume (BV/TV, higher osteoblast and osteocyte apoptosis, and higher SOST and Dickkopf-1 gene expression than the Nx+PTx 0.6% group. Nx+PTx 0.6% rat had very low serum sclerostin levels, and Nx+PTx 1.2% had intermediate sclerostin levels compared with sham group. Finally, there was a negative correlation between BV/TV and serum sclerostin. These results suggest that high dietary phosphate intake decreases bone volume in an experimental model of CKD-ABD, possibly via changes in SOST expression through a PTH-independent mechanism. These findings could have relevance for the clinical setting of CKD-ABD in patients who low turnover bone disease might

    It is well established that inherited human aldehyde dehydrogenase 2 (ALDH-2) deficiency reduces the risk for alcoholism. Kudzu plants and extracts have been used for 1,000 years in traditional Chinese medicine to treat alcoholism. Kudzu contains daidzin, which inhibits ALDH-2 and suppresses heavy drinking in rodents. Decreased drinking due to ALDH-2 inhibition is attributed to aversive properties of acetaldehyde accumulated during alcohol consumption. However not all of the anti-alcohol prop...

    Near-infrared (NIR) spectroscopy has been developed into an indispensable tool for both academic research and industrial quality control in a wide field of applications. The feasibility of NIR spectroscopy to monitor the concentration of puerarin, daidzin, daidzein and total isoflavonoid (TIF) during the extraction process of kudzu (Pueraria lobata) was verified in this work. NIR spectra were collected in transmission mode and pretreated with smoothing and derivative. Partial least square regression (PLSR) was used to establish calibration models. Three different variable selection methods, including correlation coefficient method, interval partial least squares (iPLS), and successive projections algorithm (SPA) were performed and compared with models based on all of the variables. The results showed that the approach was very efficient and environmentally friendly for rapid determination of the four quality indices (QIs) in the kudzu extraction process. This method established may have the potential to be used as a process analytical technological (PAT) tool in the future.

    Full Text Available Kudzú (P. phaseoloides and carrot (D. carota roots were transformed in this survey into different kinds of culture medium by using five different A. rhizogenes strains. These presented different behaviour both in carrot transformation by A. rhizogenes 15834, A.r.8196 and A.r.2659 strains as well as kudzu transformation by A.r.15834 and A.r.1724 strains. Transformed carrot root growth was increased in WM culture medium, whilst transformed kudzu root growth did not increase in either the same medium or in modified MS medium. Transformed carrot roots were used for G. intrarradices increase and sporulation; however, wild AMF strains, isolated from a mining area (the lower Cauca area of Antioquia, did not grow either in roots from this specie or those from kudzu, in spite of this plant having great affinity for wild AMF strains. The results represent an advance in the procedure for DNA isolation and keeping AMF collections, required for other research.

  12. Uneven dietary development: linking the policies and processes of globalization with the nutrition transition, obesity and diet-related chronic diseases

    Directory of Open Access Journals (Sweden)

    2006-03-01

    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

    The protective effect of aqueous extracts of three dietary spices, garlic, (Allium sativum), ginger (Zingiber officinale) and pepper (Capsicum frutescens) singly and combined was investigated using a rat model of chronic alcohol intake. Rats were given 30% ethanol, with or without aqueous extracts of garlic, ginger, pepper or mixture of the three administered at 200mg/kg body weight by oral gavage for 28 days. Lipid profile, lipid peroxidation, oxidative and antioxidative profiles of serum, faecal, liver, kidney, heart and brain tissues of the rats were analyzed. Alcohol treatment significantly elevated liver enzymes, lipid peroxidation, depleted antioxidant system and induced histopathological changes in the liver. These alterations were markedly ameliorated by treatment with aqueous extracts of the three spices singly or mixed at 200mg/kg body weight. These results suggest that aqueous extracts of garlic, ginger, pepper or a blend of the three protects against alcohol- induced hypercholesterolemia, lipid peroxidation, oxidative stress and liver damage.

    We examined nutrient transport in the intestines of mice exposed to chronic low-LET 137Cs gamma rays. The mice were whole-body irradiated for 3 days at dose rates of 0, 0.13 and 0.20 Gy/h, for total dose delivery of 0, 9.6 or 14.4 Gy, respectively. The mice were fed either a control diet or a diet supplemented with high levels of vitamins A, C and E. Our results showed that nutrient transport was perturbed by the chronic irradiation conditions. However, no apparent alteration of the macroscopic intestinal structures of the small intestine were observed up to day 10 after initiating irradiation. Jejunal fructose uptake measured in vitro was strongly affected by the chronic irradiation, whereas uptake of proline, carnosine and the bile acid taurocholate in the ileum was less affected. D-glucose transport did not appear to be inhibited significantly by either 9.6 or 14.4 Gy exposure. In the 14.4 Gy irradiated groups, the diet supplemented with high levels of vitamins A, C and E increased intestinal transport of fructose compared to the control diet (day 10; t test, P = 0.032), which correlated with elevated levels of vitamins A, C and E in the plasma and jejunal enterocytes. Our earlier studies with mice exposed acutely to 137Cs gamma rays demonstrated significant protection for transport of fructose, glucose, proline and carnosine. Taken together, these results suggest that high levels of vitamins A, C and E dietary supplements help preserve intestinal nutrient transport when intestines are irradiated chronically or acutely with low-LET gamma rays.

    Atlantic salmon (Salmo salar L.) parr were fed for 4 months on fish meal based diets supplemented with mercuric chloride (0, 10, or 100 mg Hg kg{sup -1} DW) or methylmercury chloride (0, 5, or 10 mg Hg kg{sup -1} DW) to assess the effects of inorganic (Hg) and organic dietary mercury on brain lipid peroxidation and neurotoxicity. Lipid peroxidative products, endogenous anti oxidant enzymes, brain histopathology, and overall behaviour were measured. Methylmercury accumulated significantly in the brain of fish fed 5 or 10 mg kg{sup -1} by the end of the experiment, and inorganic mercury accumulated significantly in the brain only at 100 mg kg{sup -1} exposure levels. No mortality or growth reduction was observed in any of the exposure groups. Fish fed 5 mg kg{sup -1} methylmercury had a significant increase (2-fold) in the antioxidant enzyme super oxide dismutase (SOD) in the brain. At dietary levels of 10 mg kg{sup -1} methylmercury, a significant increase (7-fold) was observed in lipid peroxidative products (thiobarbituric acid reactive substances, TBARS) and a subsequently decrease (1.5-fold) in anti oxidant enzyme activity (SOD and glutathione peroxidase, GSH-Px). Fish fed 10 mg kg{sup -1} methylmercury also had pathological damage (vacoulation and necrosis), significantly reduced neural enzyme activity (5-fold reduced monoamine oxidase, MAO, activity), and reduced overall post-feeding activity behaviour. Pathological injury started in the brain stem and became more widespread in other areas of the brain at higher exposure levels. Fish fed 100 mg Hg kg{sup -1} inorganic mercury had significant reduced neural MAO activity and pathological changes (astrocyte proliferation) in the brain, however, neural SOD and GSH-Px enzyme activity, lipid peroxidative products (TBARS), and post feeding behaviour did not differ from controls. Compared with other organs, the brain is particular susceptible for dietary methylmercury induced lipid peroxidative stress at relative low

    Waterborne Cu is toxic to Na(+) and Cl(-) regulation in freshwater fish, and Cu is taken up, at least in part, via the Na(+)-transport pathway in the gills. Therefore, we hypothesized that freshwater fish may mitigate the toxic effects of waterborne Cu by selecting a NaCl-enriched diet over a normal diet. We tested this hypothesis in juvenile rainbow trout (Oncorhynchus mykiss) by offering them the choice between NaCl-enriched (1.9 mmol g(-1)Na(+)) and normal (0.2 mmol g(-1)Na(+)) diets under a chronic waterborne Cu exposure of 55 microg L(-1) for a period of 28 days. Contrary to expectation, trout exhibited a preference for NaCl-enriched diet under control conditions, while exposure to chronic waterborne Cu severely disrupted their normal feeding pattern with an accompanying loss of preference for the NaCl-enriched diet. Waterborne Cu exposure also severely affected appetite and growth. Both appetite and growth gradually recovered with time, but remained significantly impaired relative to Cu-unexposed fish until the end of the exposure. Waterborne Cu exposure also significantly increased Cu accumulations in target organs (gill, liver, and gut), plasma and whole body. However, Cu accumulation decreased substantially towards the end of the exposure in target organs and whole body as well as in plasma in Cu-exposed fish with dietary choice relative to Cu-exposed fish with normal diet. These adjustments were concurrent with the gradual recovery of appetite, which also led to increased ingestion of the NaCl-enriched diet. Interestingly, this elevated dietary uptake of NaCl produced significant stimulation of Na(+) efflux in Cu-exposed fish. Subsequently, it also led to significant elevation of Na(+) levels in target organs and whole body, and restored the decrease of plasma Na(+) and Cl(-) levels in Cu-exposed fish. The NaCl supplemented diet appeared to be beneficial in compensating Na(+) and Cl(-) losses from the body induced by waterborne Cu. Overall, these results

    Full Text Available Abstract Background Targeted analgesic dietary interventions are a promising strategy for alleviating pain and improving quality of life in patients with persistent pain syndromes, such as chronic daily headache (CDH. High intakes of the omega-6 (n-6 polyunsaturated fatty acids (PUFAs, linoleic acid (LA and arachidonic acid (AA may promote physical pain by increasing the abundance, and subsequent metabolism, of LA and AA in immune and nervous system tissues. Here we describe methodology for an ongoing randomized clinical trial comparing the metabolic and clinical effects of a low n-6, average n-3 PUFA diet, to the effects of a low n-6 plus high n-3 PUFA diet, in patients with CDH. Our primary aim is to determine if: A both diets reduce n-6 PUFAs in plasma and erythrocyte lipid pools, compared to baseline; and B the low n-6 plus high n-3 diet produces a greater decline in n-6 PUFAs, compared to the low n-6 diet alone. Secondary clinical outcomes include headache-specific quality-of-life, and headache frequency and intensity. Methods Adults meeting the International Classification of Headache Disorders criteria for CDH are included. After a 6-week baseline phase, participants are randomized to a low n-6 diet, or a low n-6 plus high n-3 diet, for 12 weeks. Foods meeting nutrient intake targets are provided for 2 meals and 2 snacks per day. A research dietitian provides intensive dietary counseling at 2-week intervals. Web-based intervention materials complement dietitian advice. Blood and clinical outcome data are collected every 4 weeks. Results Subject recruitment and retention has been excellent; 35 of 40 randomized participants completed the 12-week intervention. Preliminary blinded analysis of composite data from the first 20 participants found significant reductions in erythrocyte n-6 LA, AA and %n-6 in HUFA, and increases in n-3 EPA, DHA and the omega-3 index, indicating adherence.

AD Tg mice on control diet without figs showed significant impairment in spatial learning ability compared to the wild-type mice on same diet and figs fed Tg mice as well. Significant increase in oxidative stress and reduced antioxidant status were observed in AD Tg mice. 4% figs treated AD Tg mice significantly attenuated oxidative damage, as evident by decreased lipid peroxidation and protein carbonyls and restoration of antioxidant status. Altered activities of membrane bound enzymes (Na+ K+ ATPase and acetylcholinesterase (AChE in AD Tg mice brain regions and was restored by figs treatment. Further, figs supplementation might be able to decrease the plasma levels of Aβ (1–40, 1–42 significantly in Tg mice suggesting a putative delay in the formation of plaques, which might be due to the presence of high natural antioxidants in figs. But this study warrants further extensive investigation to find a novel lead for a therapeutic target for AD from figs.

    Full Text Available Neonatal rats have a high intestinal lactase activity, which declines around weaning. Yet, the effects of lactose-containing products are often studied in adult animals. This report is on the residual, post-weaning lactase activity and on the short- and long-term effects of lactose exposure in adult rats. Acutely, the postprandial plasma response to increasing doses of lactose was studied, and chronically, the effects of a 30% lactose diet fed from postnatal (PN Day 15 onwards were evaluated. Intestinal lactase activity, as assessed both in vivo and in vitro, was compared between both test methods and diet groups (lactose vs. control. A 50%–75% decreased digestive capability towards lactose was observed from weaning into adulthood. Instillation of lactose in adult rats showed disproportionally low increases in plasma glucose levels and did not elicit an insulin response. However, gavages comprising maltodextrin gave rise to significant plasma glucose and insulin responses, indicative of a bias of the adult GI tract to digest glucose polymers. Despite the residual intestinal lactase activity shown, a 30% lactose diet was poorly digested by adult rats: the lactose diet rendered the animals less heavy and virtually devoid of body fat, whereas their cecum tripled in size, suggesting an increased bacterial fermentation. The observed acute and chronic effects of lactose exposure in adult rats cannot be explained by the residual intestinal lactase activity assessed.

    We tested the hypothesis that substitution of omega-3 fat for dietary omega-6 fat would reduce mortality and decrease Kupffer cell prostaglandin E2 (PGE2) production in a rat model of chronic sepsis. Rats were fed via gastrostomy for 12 days with isonitrogenous, isocaloric diets containing 15% of calories as either safflower oil (omega-6) or a 10:1 mixture of menhaden oil (omega-3) and safflower oil. After five days of feeding, animals received an intra-abdominal abscess of defined bacterial content. Survivors were killed on post-laparotomy day 6 in conjunction with liver perfusion and protease liver digestion for Kupffer cell isolation. Kupffer cell PGE2 production was measured by radioimmunoassay after 18 hours of cell culture and again after stimulation with 0 LPS, 10 ng/ml LPS, and 10 micrograms/LPS. Mortality was decreased in menhaden oil-fed animals compared with safflower oil-fed animals (16% vs. 35%). Kupffer cell PGE2 production was decreased in menhaden oil-fed animals at 18 hours (354 +/- 54 vs. 570 +/- 95 pg/0.1 ml; p = 0.09) and after stimulation with 10 micrograms/ml LPS (140 +/- 41 vs. 288 +/- 45 pg/0.1 ml; p = 0.03) compared with safflower oil-fed animals.

    Sub-chronic tryptophan depletion (SCTD) is proposed as an animal model for depression. Aims were to test the hypothesis and optimise the time of SCTD-induced depression-related behaviour and associated biochemical changes. Sprague Dawley rats were treated with a low tryptophan (TRP) containing diet for 0, 7 or 14 days. Peripheral and central neurochemical markers were measured. SCTD-induced depression-related behaviour was assessed by the forced swim test (FST). Model sensitivity to antidepressants was tested by concomitant treatment with paroxetine. SCTD-induced significant reductions in weight gain and measures of peripheral and central TRP. Corticosterone, aldosterone and kynurenine (K), increased whilst kynurenic acid (KA), an NMDA antagonist decreased. 5-HT(2) receptor binding Bmax was enhanced but was reversed by paroxetine. Corticosterone and aldosterone were significantly negatively-correlated to weight gain. SCTD increased floating time and reduced swimming time in the FST but were reversed by paroxetine. Aldosterone was increased at 7 and 14 days, whereas other changes maximised at 14 days. Aldosterone may be an early marker or causal link for depression development. Increased corticosterone and brain tissue 5-HT-receptor density may be correlates of depressive behaviour. Consequential increases in NMDA signalling through increased K/KA ratios suggest the model may be useful for testing novel antidepressants. PMID:22074993

    Recent work has shown that V accumulates in the kidney and is a potent inhibitor of Na+, K+-adenosinetriphosphatase (ATPase) in vitro. Thus, as a nutritionally required element, V may regulate cation transport. The effect of chronic intake of the metal on Na+, K+-ATPase in vivo has not been reported. In this study laying strain chickens were fed calcium orthovanadate for 15 mo from d 1 of age at levels of 0, 25, 50, and 100 ppm in the diet. Whole tissue homogenates and 13,000 X g fractions were analyzed for ATPase activities. Concentrations of V producing 50% inhibition of Na+, K+-ATPase activity ranged from 1.0 X 10(-5) M in liver to 1.8 X 10(-6) M in kidney, which was the most sensitive tissue tested in vitro. Mg2+ -ATPase was more resistant to V than Na+, K+-ATPase. Studies in vivo suggested a V-dependent inhibition of renal Na+, K+-ATPase. Correlation of enzyme specific activity and levels of V in kidneys suggested V-ATPase mediated alteration in renal function. PMID:6125598

    Two-year dietary studies were conducted to determine the chronic toxicity and its reversibility, and the carcinogenicity of P70(H) and P100(H) white mineral oils in Fischer-344 rats (F-344). The studies were identical in design and followed the Organization for Economic Cooperation and Development, Guidelines for Testing Chemicals, Guideline 453, 1981. Additional endpoints evaluated were: (1) extent of mineral hydrocarbon deposition in liver, kidneys, mesenteric lymph nodes, and spleen of female rats at 3, 6, 12, 18 and 24 months, and (2) reversibility of effects following cessation of exposure. Dietary concentration were 60, 120, 240, and 1,200 mg/kg/day, adjusted periodically to account for bodyweight changes. Study results were consistent with preceding subchronic studies. No treatment-related mortality, neoplastic lesions, or changes in clinical health, hematology, serum chemistry, or urine chemistry were evident in any group administered either white oil. Statistically significant higher food consumption was noted in the 1,200 mg/kg group males and females exposed to either white oil and statistically significant higher body weights were noted in the 1,200-mg/kg males during the latter portion of the P100(H) study. Higher mesenteric lymph node weights were accompanied by increased severity of infiltrating histiocytes. This occurred to a greater extent with the P70(H) than the P100(H) oil. No other histopathology of significance was observed. Mineral hydrocarbons were detected in the liver following exposure to either oil. Maximal concentrations of mineral hydrocarbons in the liver were similar with both oils but occurred more rapidly with the P70(H) oil. Liver mineral hydrocarbon content returned to near-background levels during the reversibility phase. In conclusion, lifetime exposer of F344 rats to P70(H) and P100(H) white oils resulted in only minimal findings and with no consequence to clinical health. Thus, under the conditions of these studies, the No

    Full Text Available Kudzu is a cover crop that has escaped cultivation in some subtropical and warm temperate regions. Kudzu has previously demonstrated broad intraspecific physiological plasticity while colonizing new environments. The objective of this paper was to investigate characteristics of kudzu leaflet anatomy that might contribute to its successful growth in climatically distinct environments, and to escape cultivation as well. Fresh and fixed leaflet strips of field-grown plants were analyzed. The lower epidermis of kudzu showed a higher frequency of stomata (147 ± 19 stomata mm-2 than the upper epidermis (26 ± 17 stomata mm-2. The average number of trichomes per square milimeter was 8 for both the upper and the lower epidermis. The average trichome length was 410 ± 200 mum for the upper epidermis and 460 ± 190 mum for the lower epidermis. Cuticle thickness was not considerably different between lower and upper epidermis. The leaflet blade consisted basically of two layers (upper and lower of unicellular epidermis, two layers of palisade parenchyma and one layer of spongy parenchyma. One layer of paraveinal mesophyll was found between palisade and spongy parenchyma. In conclusion, leaflets of kudzu present anatomical characteristics that might contribute to the broad physiological plasticity shown by kudzu.Kudzu é uma cultura de cobertura que se tornou invasiva em algumas regiões subtropicais e temperadas.

  1. Reduced dietary omega-6 to omega-3 fatty acid ratio and 12/15-lipoxygenase deficiency are protective against chronic high fat diet-induced steatohepatitis.

    Full Text Available Obesity is associated with metabolic perturbations including liver and adipose tissue inflammation, insulin resistance, and type 2 diabetes. Omega-6 fatty acids (ω6 promote and omega-3 fatty acids (ω3 reduce inflammation as they can be metabolized to pro- and anti-inflammatory eicosanoids, respectively. 12/15-lipoxygenase (12/15-LO enzymatically produces some of these metabolites and is induced by high fat (HF diet. We investigated the effects of altering dietary ω6/ω3 ratio and 12/15-LO deficiency on HF diet-induced tissue inflammation and insulin resistance. We examined how these conditions affect circulating concentrations of oxidized metabolites of ω6 arachidonic and linoleic acids and innate and adaptive immune system activity in the liver. For 15 weeks, wild-type (WT mice were fed either a soybean oil-enriched HF diet with high dietary ω6/ω3 ratio (11∶1, HFH, similar to Western-style diet, or a fat Kcal-matched, fish oil-enriched HF diet with a low dietary ω6/ω3 ratio of 2.7∶1 (HFL. Importantly, the total saturated, monounsaturated and polyunsaturated fat content was matched in the two HF diets, which is unlike most published fish oil studies in mice. Despite modestly increased food intake, WT mice fed HFL were protected from HFH-diet induced steatohepatitis, evidenced by decreased hepatic mRNA expression of pro-inflammatory genes and genes involved in lymphocyte homing, and reduced deposition of hepatic triglyceride. Furthermore, oxidized metabolites of ω6 arachidonic acid were decreased in the plasma of WT HFL compared to WT HFH-fed mice. 12/15-LO knockout (KO mice were also protected from HFH-induced fatty liver and elevated mRNA markers of inflammation and lymphocyte homing. 12/15-LOKO mice were protected from HFH-induced insulin resistance but reducing dietary ω6/ω3 ratio in WT mice did not ameliorate insulin resistance or adipose tissue inflammation. In conclusion, lowering dietary ω6/ω3 ratio in HF diet

  2. Body weight considerations in the B6C3F1 mouse and the use of dietary control to standardize background tumor incidence in chronic bioassays

    International Nuclear Information System (INIS)

    In B6C3F1 mice, the rate of body growth influences susceptibility to liver neoplasia and large variations in body weight can complicate the interpretation of bioassay data. The relationship between body weight and liver tumor incidence was calculated for historical control populations of male and female ad libitum-fed mice (approx. 2750 and 2300 animals, respectively) and in populations of male and female mice which had been subjected to forced body weight reduction due to either dietary restriction or exposure to noncarcinogenic chemicals (approx. 1600 and 1700, respectively). Resulting tumor risk data were then used to construct idealized weight curves for male and female B6C3F1 mice; these curves predict a terminal background liver tumor incidence of 15-20%. Use of dietary control to manipulate body growth of male B6C3F1 mice to fit the idealized weight curve was evaluated in a 2-year bioassay of chloral hydrate. Cohorts of mice were successfully maintained at weights approximating their idealized target weights throughout the study. These mice exhibited less body weight variation than their ad libitum-fed counterparts (e.g., standard deviations of body weight were 1.4 and 3.4 g for respective control groups at 36 weeks). Historical control body weight and tumor risk data from the two male mouse populations were utilized to predict background liver tumor rates for each experimental group of the chloral hydrate study. The predicted background tumor rates closely matched the observed rates for both the dietary controlled and ad libitum-fed chloral hydrate control groups when each mouse was evaluated according to either its weekly food consumption or its weekly change in body weight

    2013-01-01

    Full Text Available Aim. To investigate the role of AMPK activation and autophagy in mediating the beneficial effects of exercise and caloric restriction in obesity. Methods. Dietary-induced obesity mice were made and divided into 5 groups; one additional group of normal mice serves as control. Mice in each group received different combinations of interventions including low fat diet, caloric restriction, and exercise. Then their metabolic conditions were assessed by measuring serum glucose and insulin, serum lipids, and liver function. AMPK phosphorylation and autophagy activity were detected by western blotting. Results. Obese mice models were successfully induced by high fat diet. Caloric restriction consistently improved the metabolic conditions of the obese mice, and the effects are more prominent than the mice that received only exercise. Also, caloric restriction, exercise, and low fat diet showed a synergistic effect in the improvement of metabolic conditions. Western blotting results showed that this improvement was not related with the activation of AMPK in liver, skeletal muscle, or heart but correlates well with the autophagy activity. Conclusion. Caloric restriction has more prominent beneficial effects than exercise in dietary-induced obese mice. These effects are correlated with the autophagy activity and may be independent of AMPK activation.

    In a combined chronic toxicity/carcinogenicity study, groups of Crl:CD(SD) rats were fed 0 (2 control groups), 5000, 20,000, or 40,000 ppm (2R,4R)-monatin salt (hereafter "R,R-monatin") in the diet for up to one year in the chronic toxicity phase and up to two years in the carcinogenicity phase. There were no adverse effects on survival, incidence of palpable masses, neoplasms, organ weights, or ophthalmic examinations. The only notable effect was statistically significantly lower mean body weights and body weight gains in all treated groups generally throughout the study, which were most likely a result of caloric dilution of the test diets. Effects of long-term R,R-monatin ingestion by rats were predominantly focused on the urinary system (i.e., clinical pathology alterations indicative of electrolyte and pH imbalances, increased incidence of renal calculi, mineralization and bone hyperostosis, and increased severity of chronic progressive nephropathy). The no-observed-adverse-effect level (NOAEL) for R,R-monatin from the chronic toxicity phase was 20,000 ppm (equivalent to an exposure level of 1080 mg/kg bw/day for males and 1425 mg/kg/day for females) and from the carcinogenicity phase was 5000 ppm (equivalent to an exposure level of 238 and 302 mg/kg bw/day for males and females, respectively).

    Dietary components are important determinants of systemic inflammation, a risk factor for most chronic diseases. The Dietary Inflammatory Index (DII) was developed to assess dietary inflammatory potential. It was hypothesized that anti-inflammatory DII scores would be associated with "healthier" scores on other dietary indices. The Energy Balance Study is an observational study focusing on energy intake and expenditure in young adults; only baseline data were used for this analysis (n=430). The DII, as well as the Healthy Eating Index-2010 (HEI-2010), the Alternative Healthy Eating Index (AHEI), and the Dietary Approaches to Stop Hypertension Index (DASH) were calculated based on one to three 24-hour dietary recalls. General linear models were used to estimate least square means of the AHEI, HEI-2010, and DASH according to DII quartiles. Those with higher (ie, more proinflammatory) DII scores were more likely to be males, have less than a completed college education, and be younger. In addition, those with higher scores for cognitive restraint for eating or drive for thinness had lower (ie, anti-inflammatory) DII scores. Linear regression analyses indicated that as the DII increased, the AHEI, HEI-2010, and DASH dietary indices decreased (ie, became more unhealthy, all Pfactor for chronic disease. PMID:26923507

    Common dietary components including vitamins A and D, omega-3 and probiotics are now widely accepted to be essential to protect against many diseases with an inflammatory nature. On the other hand, high-fat diets are documented to exert multiple deleterious effects, including fatty liver diseases. Here we discuss the effect of dietary components on regulatory T cell (Treg) homeostasis, a central element of the immune system to prevent chronic tissue inflammation. Accordingly, evidence on the impact of dietary components on diseases in which Tregs play an influential role will be discussed. We will review chronic tissue-specific autoimmune and inflammatory conditions such as inflammatory bowel disease, type 1 diabetes mellitus, multiple sclerosis, rheumatoid arthritis and allergies among chronic diseases where dietary factors could have a direct influence via modulation of Tregs homeostasis and functions.

    Restoring natural forests after field abandon-ment is a land management objective that fosters the re-covery of forest biodiversity. We performed seeding and transplanting of native tree species 40 years after the abandonment of an arable field that became dominated by a dwarf bamboo (Pleioblastus chino (Franch. et Sav.) Makino) and by kudzu (Pueraria lobata (Willd.) Ohwi). By permutation tests, the removal of competing vegetation (gap creation) significantly increased the survival of three seeded species of Fagaceae and of eight transplanted spe-cies. In contrast, intact vegetation prevented most indi-viduals of all species from surviving for 1 year after planting. The lack of natural recruitment of Fagaceae in the nonseeded subplots indicated that seed limitation was a cause of the slow afforestation. Although litter accumula-tion in gaps at the time of seeding slightly increased sur-vival for late-germinating Quercus myrsinifolia Blume and Castanopsis sieboldii (Makino) Hatus. ex T. Yamaz. et Mashiba, the effect was not consistent among plots and was not statistically significant. Our results suggest that for successful afforestation using native trees in abandoned fields, it will be necessary to remove competitive native species to avoid severe limitations on microsite availability and that simultaneous tree establishment by seeding or transplanting should be implemented to accelerate the establishment of native tree species.

  7. Foods, Nutrients, and Dietary Patterns: Interconnections and Implications for Dietary Guidelines.

    2016-05-01

    Dietary guidelines provide evidence-based statements on food choices to meet nutritional requirements and reduce the risk of prevailing chronic disease. They involve a substantial amount of research translation, and their implementation has important health consequences. Foods, however, are complex combinations of nutrients and other compounds that act synergistically within the food and across food combinations. In addition, the evidence base underpinning dietary guidelines accesses research that reflects different study designs, with inherent strengths and limitations. We propose a systematic approach for the review of evidence that begins with research on dietary patterns. This research will identify the combinations of foods that best protect, or appear deleterious to, health. Next, we suggest that evidence be sought from research that focuses on the effects of individual foods. Finally, nutrient-based research should be considered to explain the mechanisms by which these foods and dietary patterns exert their effects, take into account the effects of ingredients added to the food supply, and enable assessments of dietary sufficiency. The consideration of individual nutrients and food components (e.g., upper limits for saturated fat, added sugar, and sodium) provides important benchmarks for evaluating overall diet quality. The concepts of core and discretionary foods (nutrient-rich and nutrient-poor foods, respectively) enable distinctions between foods, and this has implications for the relation between food policy and food manufacturing. In summary, evidence supporting healthy dietary patterns provides the foundation for the development of dietary guidelines. Further reference to individual foods and nutrients follows from the foundation of healthy dietary patterns. PMID:27184272

    Full Text Available Objectives: To assess the dietary habits and food avoidance-behavior in patients with Chronic Fatigue Syndrome (CFS. Methods: Cross-sectional pilot study with 28 patients diagnosed with severe CFS. Eating habits were assessed with a food frequency questionnaire and 3-day food records. We analyzed variables related to dietary restrictions induced by symptoms or external information. Results: The most prevalent restrictions were for dairy products and gluten-containing grains, with 22 and 15 restricting patients, respectively. Patients reported different digestive symptoms, which did not improve with the use of exclusion diets. Thirteen patients had received information against the intake of certain foods through different sources. Six cases of grains restriction and 11 of dairy were compatible with a counseling-induced pattern of exclusion. Conclusions: There is not a homogeneous pattern of food avoidance. Dietary restrictions should be based on a proven food allergy or intolerance. Dietary counseling should be based on sound nutritional knowledge.Objetivos: Valorar los hábitos dietéticos y la conducta de evitación alimenticia en pacientes con Síndrome de Fatiga Crónica.

    Dahl, Wendy J; Stewart, Maria L

    2015-11-01

    It is the position of the Academy of Nutrition and Dietetics that the public should consume adequate amounts of dietary fiber from a variety of plant foods. Dietary fiber is defined by the Institute of Medicine Food Nutrition Board as "nondigestible carbohydrates and lignin that are intrinsic and intact in plants." Populations that consume more dietary fiber have less chronic disease. Higher intakes of dietary fiber reduce the risk of developing several chronic diseases, including cardiovascular disease, type 2 diabetes, and some cancers, and have been associated with lower body weights. The Adequate Intake for fiber is 14 g total fiber per 1,000 kcal, or 25 g for adult women and 38 g for adult men, based on research demonstrating protection against coronary heart disease. Properties of dietary fiber, such as fermentability and viscosity, are thought to be important parameters influencing the risk of disease. Plant components associated with dietary fiber may also contribute to reduced disease risk. The mean intake of dietary fiber in the United States is 17 g/day with only 5% of the population meeting the Adequate Intake. Healthy adults and children can achieve adequate dietary fiber intakes by increasing their intake of plant foods while concurrently decreasing energy from foods high in added sugar and fat, and low in fiber. Dietary messages to increase consumption of whole grains, legumes, vegetables, fruits, and nuts should be broadly supported by food and nutrition practitioners. PMID:26514720

    International Nuclear Information System (INIS)

    The dietary life of humans varies with the environment where they live and has been changing with time. It has become possible to examine such changes by using stable carbon and nitrogen isotope composition as a chemical tool. The present report outlines recent developments in the application of this tool and compares the dietary ecologies of various human groups from the viewpoint of isotope geochemistry. The history of the application of this tool to dietary analysis is summarized first, and features of the carbon and nitrogen isotope composition in animals and their relations with the food chain are outlined. The dietary ecology of the current people is then discussed in relation to the isotope composition in food, the isotope composition in hair of the current people, and determination of food habit of specific groups of people from such isotope compositions. For prediction of dietary composition, the report presents a flow chart for an algorism which is based on the Monte Carlo method. It also outlines processes for analyzing food habits of people in the prehistoric age, focusing on distribution of isotope composition in humans over the world. (N.K.)

    Full Text Available Kudzu (Pueraria lobata is one of the earliest medicinal plants used to treat alcohol abuse in traditional Chinese medicine for more than a millennium. However, little is known about its effects on chronic alcoholic liver injury. Therefore, the present study observed the effects of puerariae radix extract (RPE on chronic alcoholic liver injury as well as Kupffer cells (KCs activation to release tumor necrosis factor alpha (TNF-α induced by gut-derived endotoxin in rats and macrophage cell line. RPE was observed to alleviate the pathological changes and lipids deposition in liver tissues as well as the serum alanine aminotransferase (ALT, aspartate aminotransferase (AST, and hepatic gamma-glutamyl transpeptidase (GGT activity. Meanwhile, RPE inhibited KCs activation and subsequent hepatic TNF-α expression and downregulated the protein expression of endotoxin receptors, lipopolysaccharide binding protein (LBP, CD14, Toll-like receptor (TLR 2, and TLR4 in chronic alcohol intake rats. Furthermore, an in vitro study showed that RPE inhibited the expression of TNF-α and endotoxin receptors, CD14 and TLR4, induced by LPS in RAW264.7 cells. In summary, this study demonstrated that RPE mitigated liver damage and lipid deposition induced by chronic alcohol intake in rats, as well as TNF-α release, protein expression of endotoxin receptors in vivo or in vitro.

    Limiting the saturated fatty acid (SAFA) consumption forms the basis of dietary fat recommendations for heart health, despite several meta-analyses demonstrating no link between dietary SAFA and the risk of cardiovascular disease (CVD). Three experts on dietary fat and health discussed the evidence of reducing SAFA intake at a symposium of the Federation of European Nutrition Societies in Berlin, Germany, October 23, 2015. Ronald P. Mensink, Maastricht University, the Netherlands, discussed the evidence linking dietary fatty acids and CVD risk. He emphasized the importance of the replacement nutrient(s) when SAFA intake is reduced. Julie Lovegrove, University of Reading, UK, addressed the question of whether higher intakes of unsaturated fatty acids are beneficial. She discussed the replacement of SAFA by polyunsaturated fatty acids (PUFA) and monounsaturated fatty acids (MUFA), noting the reduction in CVD risk with PUFA replacement and in CVD risk markers with MUFA replacement of SAFA. Ursula Schwab, University of Eastern Finland, Kuopio, Finland, discussed the importance of dietary patterns in achieving reduced risk of CVD, observing that several dietary patterns following the principles of a health-promoting diet and adapted to local customs, food preferences and seasonality are effective in reducing the risk of CVD, type 2 diabetes and other chronic diseases. This paper summarizes the symposium presentations. PMID:27251664

  12. Effects of dietary interventions on incidence and progression of CKD.

    Traditional strategies for management of patients with chronic kidney disease (CKD) have not resulted in any change in the growing prevalence of CKD worldwide. A historic belief that eating healthily might ameliorate kidney disease still holds credibility in the 21(st) century. Dietary sodium restriction to diet rich in fruits and vegetables and increased water consumption corresponding to a urine output of 3-4 l daily might slow the progression of early CKD, polycystic kidney disease or recurrent kidney stones. Current evidence suggests that a reduction in dietary net acid load could be beneficial in patients with CKD, but the supremacy of any particular diet has yet to be established. More trials of dietary interventions are needed, especially in diabetic nephropathy, before evidence-based recommendations can be made. In the meantime, nephrologists should discuss healthy dietary habits with their patients and provide individualized care aimed at maximizing the potential benefits of dietary intervention, reducing the incidence of CKD and delaying its progression to end-stage renal disease. Keeping in mind the lack of data on hard outcomes, dietary recommendations should take into account barriers to adherence and be tailored to different cultures, ethnicities and geographical locations.

    1993-01-01

    Studies of the dietary practices of athletes report that nutritional supplements are commonly used. Supplementation practices vary between sports and individual athletes; however, there is evidence that at least some athletes use a large number of supplements concurrently, often in doses that are very high in comparison with normal dietary intakes. In exploring supplementation practices we propose a classification system separating the supplements into dietary supplements and nutritional erogogenic aids. The dietary supplement is characterised as a product which can be used to address physiological or nutritional issues arising in sport. It may provide a convenient or practical means of consuming special nutrient requirements for exercise, or it may be used to prevent/reverse nutritional deficiencies that commonly occur among athletes. The basis of the dietary supplement is an understanding of nutritional requirements and physiological effects of exercise. When the supplement is used to successfully meet a physiological/nutritional goal arising in sport it may be demonstrated to improve sports performance. While there is some interest in refining the composition or formulation of some dietary supplements, the real interest belongs to the use or application of the supplement; i.e. educating athletes to understand and achieve their nutritional needs in a specific sports situation. The sports drink (carbohydrate-electrolyte replacement drink) is a well known example of a dietary supplement. Scientific attitudes towards the sports drink have changed over the past 20 years. Initial caution that carbohydrate-electrolyte fluids compromise gastric emptying during exercise has now been shown to be unjustified. Numerous studies have shown that 5 to 10% solutions of glucose, glucose polymers (maltodextrins) and other simple sugars all have suitable gastric emptying characteristics for the delivery of fluid and moderate amounts of carbohydrate substrate.

    • Recently, diet-disease relations have been recommended to be looked for through dietary pattern approach rather than traditional approach (nutrient or food-oriented approach. Dietary pattern analysis allows consideration of the entire diet, rather than individual foods or ingredients. This approach can be particularly useful when traditional analyses in nutritional epidemiology cannot move beyond weak associations. The dietary pattern approach is more realistic than the food-based or nutrient approach, in that inter-correlations and biological interactions between foods and nutrients confound the associations of a single food or nutrient with a certain chronic disease. Several studies provide evidence supporting use of the dietary pattern approach in nutritional epidemiology. Most of these studies indicate that empirically derived food intake patterns by statistical methods are related to chronic diseases. This review aims to provide more detailed information about the methods of measurement, advantages and disadvantages of the dietary pattern approach and to assess whether major dietary patterns are related to the prevalence of metabolic syndrome and insulin resistance.

    Full Text Available BACKGROUND: The association of dietary pattern with chronic diseases has been investigated widely in western countries. However, information is quite limited among children in China. Our study is aimed to identify the dietary patterns of Chinese children and examine their association with obesity and related cardiometabolic risk factors. METHODS: A total of 5267 children were selected using multistage random sampling from 30 primary schools of 5 provincial capital cities in China. Dietary intake was derived from 24 hour dietary recall for three consecutive days. Anthropometric measurements, glucose and lipid profiles were obtained. Factor analysis combined with cluster analysis was used for identifying major dietary patterns. The associations of dietary patterns with obesity and related cardiometabolic risk factors were examined by logistic regression analysis. RESULTS: Three mutually exclusive dietary patterns were identified, which were labeled as the healthy dietary pattern, the transitive dietary pattern, and the Western dietary pattern. Compared with children of the healthy dietary pattern, the multiple-adjusted odds ratios (95% confidence interval (CI of obesity were 1.11 (0.89-1.38 for children with the transitive dietary pattern and 1.80 (1.15-2.81 for children with the Western dietary pattern, which was 1.31 (95%CI 1.09-1.56 and 1.71 (95%CI: 1.13-2.56, respectively, for abdominal obesity. The Western dietary pattern was associated with significantly higher concentrations of low-density lipoprotein cholesterol (P<.001, triglycerides (P<.001, systolic blood pressure (P = 0.0435 and fasting glucose (P = 0.0082 and a lower concentration of high-density lipoprotein cholesterol (P = 0.0023, as compared with the healthy dietary pattern.

  1. Polyphenols as dietary supplements: A double-edged sword

    Full Text Available Keith R Martin, Christy L AppelNutrition Program, Healthy Lifestyles Research Center, College of Nursing and Health Innovation, Arizona State University, Mesa, AZ, USAAbstract: Increased consumption of fruits and vegetables is associated with a lower risk of chronic disease such as cardiovascular disease, some forms of cancer, and neurodegeneration. Pro-oxidant-induced oxidative stress contributes to the pathogenesis of numerous chronic diseases and, as such, dietary antioxidants can quench and/or retard such processes. Dietary polyphenols, ie, phenolic acids and flavonoids, are a primary source of antioxidants for humans and are derived from plants including fruits, vegetables, spices, and herbs. Based on compelling evidence regarding the health effects of polyphenol-rich foods, new dietary supplements and polyphenol-rich foods are being developed for public use. Consumption of such products can increase dietary polyphenol intake and subsequently plasma concentrations beyond expected levels associated with dietary consumption and potentially confer additional health benefits. Furthermore, bioavailability can be modified to further increase absorption and ultimately plasma concentrations of polyphenols. However, the upper limit for plasma concentrations of polyphenols before the elaboration of adverse effects is unknown for many polyphenols. Moreover, a considerable amount of evidence is accumulating which supports the hypothesis that high-dose polyphenols can mechanistically cause adverse effects through pro-oxidative action. Thus, polyphenol-rich dietary supplements can potentially confer additional benefits but high-doses may elicit toxicity thereby establishing a double-edge sword in supplement use.Keywords: antioxidant, bioavailability, flavonoids, polyphenols, supplement

    This study examined the effects of macronutrient diets on sleep quantity and quality. Using a repeated-measures, randomized crossover study design, 36 young adults served as their own control, and consumed high protein, carbohydrate, fat, and control diets. Treatment orders were counterbalanced across the dietary groups. Following consumption of the study diets, sleep measures were examined for within-subject differences. Fatty acid intakes and serum lipids were further analyzed for differences. Sleep actigraphs indicated wake times and wake minutes (after sleep onset) were significantly different when comparing consumption of macronutrient diets and a control diet. Post hoc testing indicated high carbohydrate intakes were associated with significantly shorter (p Sleep Quality Index© post hoc results indicated high fat intake was associated with significantly better (p sleep in comparison with the other diets. These results highlight the effects that dietary manipulations may have on sleep. PMID:27170039

  5. Is it dietary insulin?

    In humans the primary trigger of insulin-specific immunity is a modified self-antigen, that is, dietary bovine insulin, which breaks neonatal tolerance to self-insulin. The immune response induced by bovine insulin spreads to react with human insulin. This primary immune response induced in the gut immune system is regulated by the mechanisms of oral tolerance. Genetic factors and environmental factors, such as the gut microflora, breast milk-derived factors, and enteral infections, control the development of oral tolerance. The age of host modifies the immune response to oral antigens because the permeability of the gut decreases with age and mucosal immune response, such as IgA response, develops with age. The factors that control the function of the gut immune system may either be protective from autoimmunity by supporting tolerance, or they may induce autoimmunity by abating tolerance to dietary insulin. There is accumulating evidence that the intestinal immune system is aberrant in children with type 1 diabetes (T1D). Intestinal immune activation and increased gut permeability are associated with T1D. These aberrancies may be responsible for the impaired control of tolerance to dietary insulin. Later in life, factors that activate insulin-specific immune cells derived from the gut may switch the response toward cytotoxic immunity. Viruses, which infect beta cells, may release autoantigens and potentiate their presentation by an infection-associated "danger signal." This kind of secondary immunization may cause functional changes in the dietary insulin primed immune cells, and lead to the infiltration of insulin-reactive T cells to the pancreatic islets.

    The most widely spread eating habit is characterized by a reduced intake of dietary fiber, an increased intake of simple sugars, a high intake of refined grain products, an altered fat composition of the diet, and a dietary pattern characterized by a high glycemic load, an increased body weight and reduced physical activity. In this chapter the effects of this eating pattern on disease risk will be outlined. There are no epidemiological studies showing that the increase of glucose, fructose or sucrose intake is directly and independently associated with an increased risk of atherosclerosis or coronary heart disease (CHD). On the other hand a large number of studies has reported a reduction of fatal and non-fatal CHD events as a function of the intake of complex carbohydrates--respectively 'dietary fiber' or selected fiber-rich food (e.g., whole grain cereals). It seems that eating too much 'fast' carbohydrate [i.e., carbohydrates with a high glycemic index (GI)] may have deleterious long-term consequences. Indeed the last decades have shown that a low fat (and consecutively high carbohydrate) diet alone is not the best strategy to combat modern diseases including atherosclerosis. Quantity and quality issues in carbohydrate nutrient content are as important as they are for fat. Multiple lines of evidence suggest that for cardiovascular disease prevention a high sugar intake should be avoided. There is growing evidence of the high impact of dietary fiber and foods with a low GI on single risk factors (e.g., lipid pattern, diabetes, inflammation, endothelial function etc.) as well as also the development of the endpoints of atherosclerosis especially CHD.

    Schwedt, Todd J

    2014-01-01

    Chronic migraine is a disabling neurologic condition that affects 2% of the general population. Patients with chronic migraine have headaches on at least 15 days a month, with at least eight days a month on which their headaches and associated symptoms meet diagnostic criteria for migraine. Chronic migraine places an enormous burden on patients owing to frequent headaches; hypersensitivity to visual, auditory, and olfactory stimuli; nausea; and vomiting. It also affects society through direct and indirect medical costs. Chronic migraine typically develops after a slow increase in headache frequency over months to years. Several factors are associated with an increased risk of transforming to chronic migraine. The diagnosis requires a carefully performed patient interview and neurologic examination, sometimes combined with additional diagnostic tests, to differentiate chronic migraine from secondary headache disorders and other primary chronic headaches of long duration. Treatment takes a multifaceted approach that may include risk factor modification, avoidance of migraine triggers, drug and non-drug based prophylaxis, and abortive migraine treatment, the frequency of which is limited to avoid drug overuse. This article provides an overview of current knowledge regarding chronic migraine, including epidemiology, risk factors for its development, pathophysiology, diagnosis, management, and guidelines. The future of chronic migraine treatment and research is also discussed. PMID:24662044

    Full Text Available Dietary fi bre is a group of food components which is resistant to digestive enzymes and found mainly in cereals, fruits and vegetables. Dietary fi ber and whole grains contain a unique blend of bioactive components including resistant starches, vitamins, minerals, phytochemicals and antioxidants. Dietary fi ber which indigestible in human small intestinal, on the other hand digested completely or partially fermented in the large intestine, is examined in two groups: water-soluble and water insoluble organic compounds. Dietary fi ber can be separated into many different fractions. These fractions include arabinoxylan, inulin, pectin, bran, cellulose, β-glucan and resistant starch. Dietary fi bres compose the major component of products with low energy value that have had an increasing importance in recent years. Dietary fi bres also have technological and functional properties that can be used in the formulation of foods, as well as numerous benefi cial effects on human health. Dietary fi bre components organise functions of large intestine and have important physiological effects on glucose, lipid metabolism and mineral bioavailability. Today, dietary fi bers are known to be protective effect against certain gastrointestinal diseases, constipation, hemorrhoids, colon cancer, gastroesophageal refl ux disease, duodenal ulcer, diverticulitis, obesity, diabetes, stroke, hypertension and cardiovascular diseases. In this review the physicochemical and biological properties of dietary fi bers and their important implications on human health will be investigated.

    2015-03-01

    Characteristics of the Western diet that fueled the obesity epidemic may also impact kidney disease incidence and progression. Enlarging portion sizes over the past half century has been accompanied by increased intake of protein, sodium, and processed foods while consumption of fruits and vegetables has declined. Overall dietary patterns play a strong role for chronic disease risk including chronic kidney disease. While dietary patterns high in fresh fruits and vegetables and low in red meats, such as the Mediterranean diet, decrease the risk of chronic diseases, the Western diet, characterized by high intake of red meat, animal fat, sweets, and desserts and low intake of fresh fruits and vegetables and low-fat dairy products, increases risk of chronic diseases. In this article, we review the potential mechanisms whereby several key characteristics of the typical Western diet may impact kidney disease incidence and progression. We also discuss a public health policy initiative to improve dietary choices. Reducing protein intake to the recommended daily allowance of 0.8 g/kg/day and increasing intake of fruit and vegetables and fiber may mitigate kidney disease progression and reduce risk of cardiovascular disease and mortality.

  13. Dietary protein intake and human health.

    A protein consists of amino acids (AA) linked by peptide bonds. Dietary protein is hydrolyzed by proteases and peptidases to generate AA, dipeptides, and tripeptides in the lumen of the gastrointestinal tract. These digestion products are utilized by bacteria in the small intestine or absorbed into enterocytes. AA that are not degraded by the small intestine enter the portal vein for protein synthesis in skeletal muscle and other tissues. AA are also used for cell-specific production of low-molecular-weight metabolites with enormous physiological importance. Thus, protein undernutrition results in stunting, anemia, physical weakness, edema, vascular dysfunction, and impaired immunity. Based on short-term nitrogen balance studies, the Recommended Dietary Allowance of protein for a healthy adult with minimal physical activity is currently 0.8 g protein per kg body weight (BW) per day. To meet the functional needs such as promoting skeletal-muscle protein accretion and physical strength, dietary intake of 1.0, 1.3, and 1.6 g protein per kg BW per day is recommended for individuals with minimal, moderate, and intense physical activity, respectively. Long-term consumption of protein at 2 g per kg BW per day is safe for healthy adults, and the tolerable upper limit is 3.5 g per kg BW per day for well-adapted subjects. Chronic high protein intake (>2 g per kg BW per day for adults) may result in digestive, renal, and vascular abnormalities and should be avoided. The quantity and quality of protein are the determinants of its nutritional values. Therefore, adequate consumption of high-quality proteins from animal products (e.g., lean meat and milk) is essential for optimal growth, development, and health of humans. PMID:26797090

    Full Text Available Since their introduction in 1921, high-fat, low-carbohydrate "ketogenic" diets have been used worldwide for refractory childhood epilepsy. Approximately half of the children have at least half their seizures reduced, including 15% who are seizure free. The mechanisms of action of dietary therapies are under active investigation and appear to involve mitochondria. Once perceived as a last resort, modifications to initiation and maintenance, as well as the widespread use of pre-made ketogenic formulas have allowed dietary treatment to be used earlier in the course of epilepsy. For infantile spasms (West syndrome specifically, the ketogenic diet is successful about 50% of the time as a first-line treatment. New "alternative" diets such as the modified Atkins diet were created in 2003 and can be started more easily and are less restrictive. They may have particular value for countries in Asia. Side effects include constipation, dyslipidemia, growth slowing, acidosis, and kidney stones. Additionally, neurologists are studying ketogenic diets for conditions other than epilepsy, including Alzheimer's disease, autism, and brain tumors.

    Many laboratory studies and human epidemiological data suggest that most cancer deaths are attributable to lifestyle, including nutritional factors and tobacco and alcohol consumption. Tobacco consumption is causally related to cancer of the lung, mouth, larynx, esophagus, bladder, kidney, and pancreas. Nutrients and non-nutrient dietary components probably account for cancer of the colon, breast, prostate, and stomach. This report is based on literature and our own data pertaining to the role of dietary fat, calories, and fiber in the development of colon and breast cancer. We also discuss the evidence from epidemiological, mechanistic, and preclinical efficacy studies indicating a protective effect of micronutrients, non-nutrients, and certain antioxidants in food against oral and lung cancers. Given the continuing cancer burden and the relatively slow impact of proven cancer treatment strategies in reducing cancer mortality, it is essential to evaluate promising nutrients and non-nutrients in foods as chemopreventive agents in persons at increased risk for cancer. Development of reliable intermediate biomarkers is valuable for clinical chemoprevention intervention trials. The purpose of this report is to provide the reader with plausible approaches to cancer control. PMID:9349690

    Full Text Available Abstract Introduction Epidemiological studies have raised concerns about the role of dietary patterns on the risk of chronic diseases and also in the formulation of better informed nutrition policies. Objective The development of a dietary availability patterns according to geographic regions in Brazil. Methodology The 2002-2003 Brazilian Household Budget Survey was conducted in 48,470 households. Dietary availability patterns were identified by Principal Component Analysis using as a unit of analysis the survey's Primary Sampling Units (PSUs and purchased amounts for 21 food groups. Each of the extracted dietary availability patterns was regressed on socioeconomics categories. Results There were no differences in dietary availability patterns between urban and rural areas. In all regions, a rice and beans pattern was identified. This pattern explained 15% to 28% of the variance dependent on the region of the country. In South, Southeast and Midwest regions, a mixed pattern including at least 10 food groups explaining 8% to 16% of the variance. In the North region (Amazon forest included the first pattern was based on fish and nuts and then it was designed as regional pattern. In multiple linear regression the rice and beans pattern was associated with the presence of adolescents in the households, except for North region, whereas the presence of adolescents was associated with the Regional pattern. A mixed patterns were associated with a higher income and education (p Conclusion The rice and beans and regional dietary availability patterns, both considered healthy eating patterns are still important in the country. Brazil has taken many actions to improve nutrition as part of their public health policies, the data of the Household Budget Survey could help to recognize the different food choices in the large regions of the country.

  4. Gut microbiota and cardiometabolic outcomes: influence of dietary patterns and their associated components.

    Wong, Julia M W

    2014-07-01

    Many dietary patterns have been associated with cardiometabolic risk reduction. A commonality between these dietary patterns is the emphasis on plant-based foods. Studies in individuals who consume vegetarian and vegan diets have shown a reduced risk of cardiovascular events and incidence of diabetes. Plant-based dietary patterns may promote a more favorable gut microbial profile. Such diets are high in dietary fiber and fermentable substrate (ie, nondigestible or undigested carbohydrates), which are sources of metabolic fuel for gut microbial fermentation and, in turn, result in end products that may be used by the host (eg, short-chain fatty acids). These end products may have direct or indirect effects on modulating the health of their host. Modulation of the gut microbiota is an area of growing interest, and it has been suggested to have the potential to reduce risk factors associated with chronic diseases. Examples of dietary components that alter the gut microbial composition include prebiotics and resistant starches. Emerging evidence also suggests a potential link between interindividual differences in the gut microbiota and variations in physiology or predisposition to certain chronic disease risk factors. Alterations in the gut microbiota may also stimulate certain populations and may assist in biotransformation of bioactive components found in plant foods. Strategies to modify microbial communities may therefore provide a novel approach in the treatment and management of chronic diseases. PMID:24898225

    The increasing incidence of nutrition-related chronic diseases worldwide has raised people's awareness of dietary quality. Most existing studies on the topic of changing nutrition patterns measure dietary quality by single macronutrient indicators or anthropometric outcomes. However, such an approach is often too narrow to provide a picture of overall dietary quality and is sometimes even misleading. This study contributes to the existing literature by taking into account that the analysis of dietary quality comprises two dimensions: the adequate intake of vitamins and minerals, as well as the moderate intake of nutrients that increase the risk of chronic diseases. Thereby, we apply Grossman's health investment model to the analysis of the demand for dietary quality, explicitly addressing the different dimensions of dietary quality and the intertemporal character of health investments. We apply our approach to Russia using data from the Russia Longitudinal Monitoring Survey from 1996 to 2008. Our results show that intake levels of vitamins and minerals as well as saturated and total fatty acids increased after 1998 along with economic recovery, while the intake of fiber decreased. Our econometric results imply an income elasticity of vitamins and minerals of 0.051, and an income elasticity of fats of 0.073. Overall, our results are in line with an ongoing nutrition transition in the Russian Federation, which is marked by decreasing deficiencies in vitamins and minerals, as well as the increasing consumption of fats with its accompanying negative health consequences.

    Dietary supplements are widely used and offer the potential to improve health if appropriately targeted to those in need. Inadequate nutrition and micronutrient deficiencies are prevalent conditions that adversely affect global health. Although improvements in diet quality are essential to address these issues, dietary supplements and/or food fortification could help meet requirements for individuals at risk of deficiencies. For example, supplementation with vitamin A and iron in developing countries, where women of reproductive age, infants and children often have deficiencies; with folic acid among women of reproductive age and during pregnancy; with vitamin D among infants and children; and with calcium and vitamin D to ensure bone health among adults aged ≥65 years. Intense debate surrounds the benefits of individual high-dose micronutrient supplementation among well-nourished individuals because the alleged beneficial effects on chronic diseases are not consistently supported. Daily low-dose multivitamin supplementation has been linked to reductions in the incidence of cancer and cataracts, especially among men. Baseline nutrition is an important consideration in supplementation that is likely to modify its effects. Here, we provide a detailed summary of dietary supplements and health outcomes in both developing and developed countries to help guide decisions about dietary supplement recommendations.

    2010-12-01

    Full Text Available Advanced glycation end products (AGEs are a heterogeneous, complex group of compounds that are formed when reducing sugar reacts in a non-enzymatic way with amino acids in proteins and other macromolecules. This occurs both exogenously (in food and endogenously (in humans with greater concentrations found in older adults. While higher AGEs occur in both healthy older adults and those with chronic diseases, research is progressing to both quantify AGEs in food and in people, and to identify mechanisms that would explain why some human tissues are damaged, and others are not. In the last twenty years, there has been increased evidence that AGEs could be implicated in the development of chronic degenerative diseases of aging, such as cardiovascular disease, Alzheimer’s disease and with complications of diabetes mellitus. Results of several studies in animal models and humans show that the restriction of dietary AGEs has positive effects on wound healing, insulin resistance and cardiovascular diseases. Recently, the effect of restriction in AGEs intake has been reported to increase the lifespan in animal models. This paper will summarize the work that has been published for both food AGEs and in vivo AGEs and their relation with aging, as well as provide suggestions for future research.

    Objective To observe the bone morphology changes in chronic renal failure rats that were fed with different levels of dietary phosphorus for long time. Methods Twenty four S-D rats were divided into high-phosphorus diet (HP group), low phosphorus diet (LP group), model group, sham operation group (sham group) (n=6). 5/6 nephrectomy model of chronic renal failure were prepared. After 3 weeks, the first 3 groups received high phosphorus (P 1.2%, calcium 1.6%), low phosphorus (P 0.2%, calcium 0.5%) and normal phosphorus (P 0.9%, 1.2% calcium) diet. The sham group received normal phosphorus diet, too. After the serum creatinine levels were tested at week 27, the rats were sacrificed, and their femur were removed, fixed-embedded, and examined with Giemsa, Von Kossa staining. Trabecular bone volume calculation (TBV), osteoblast index (OBI), the osteoclast index (OCI) and osteoid volume (OV / TV) were measured, and the morphological changes of cortical bone were observed. By tetracycline double labeling technique, bone formation rate (MAR) was analyzed. Results The survival number in HP, LP, model group, and Sham group were 6, 3, 5, 6 respectively. In the model group, TBV, OBI, OCI, OV / TV were significantly increased compared with those in the sham group (20.2± 6.3 vs. 14.4±5.2, P < 0.05; 141.0±53.3 vs. 80.0±24.1, P < 0.05; 9.4±3.0 vs. 4.5±1.3, P < 0.01; 1.14±0.02 vs. 0.21±0.03, P < 0.01), and so were MAR (2.1±0.4 vs. 0.8±0.2, P < 0.01). These changes in high-dose HP group were even more evident than those in the model group (all P < 0.05), but the cortical bone porosity was increased. TBV, OCI, MAR in LP rats were significantly lower than those in the model group, but OV/TV increased. Conclusion long-term high-phosphorus diet in rats with chronic renal failure can significantly increase bone turnover rate, increase cancellous bone and cortical bone loss. Although long-term low phosphorus diet can effectively correct the increased rate

    Population studies have shown a strong association between dietary intake of polyphenols and reduced risk of cardiovascular disease. These associations have been confirmed to some extent by intervention studies which have shown improvements in vascular function and blood pressure with certain polyphenols or food extracts rich in polyphenols. The mechanisms involved in the bioactivity of dietary polyphenols is still under active investigation. It is unlikely that polyphenols act as antioxidants in vivo. Evidence suggests that dietary polyphenols or their metabolites act as signalling molecules and can increase nitric oxide bioavailability and induce protective enzymes. This review will outline some of the key issues in dietary polyphenol research that suggest mechanistic insights into the action of these bioactive compounds. There are a number of issues that remain to be resolved in bridging the gap between observational studies and intervention trials using food extracts or pure polyphenol compounds. PMID:27095227

The EFSA Comprehensive European Food Consumption Database was used to estimate chronic dietary exposure to iAs using 28 surveys from 17 European countries. According to the scenarios used for the treatment of left-censored data, mean dietary exposure among infants, toddlers and other children ranged from 0.20 to 1.37 μg/kg b.w. per day, while the 95th percentile dietary exposure estimates ranged from 0.36 to 2.09 μg/kg b.w. per day. Mean dietary exposure among the adult population (including adults, elderly and very elderly ranged from 0.09 to 0.38 μg/kg b.w. per day, and 95th percentile dietary exposure estimates ranged from 0.14 to 0.64 μg/kg b.w. per day. For all the age classes except infants and toddlers, the main contributor to dietary exposure to iAs was the food group ‘Grain-based processed products (non rice-based’, in particular, wheat bread and rolls. Other food groups that were important contributors to iAs exposure were rice, milk and dairy products (main contributor in infants and toddlers, and drinking water. The most important sources of uncertainty in the present assessment are related to the heterogeneity of the food consumption data, the conversion of tAs into iAs and to the treatment of the left-censored data.

    Phosphorus retention plays a pivotal role in the onset of mineral and bone disorders (MBD) in chronic kidney disease (CKD). Phosphorus retention commonly occurs as a result of net intestinal absorption exceeding renal excretion or dialysis removal. The dietary phosphorus load is crucial since the early stages of CKD, throughout the whole course of the disease, up to dialysis-dependent end-stage renal disease. Agreement exits regarding the need for dietary phosphate control, but it is quite ch...

    2016-08-01

    The objective of this study was to derive food-based dietary guidelines for the Dutch population. The dietary guidelines are based on 29 systematic reviews of English language meta-analyses in PubMed summarizing randomized controlled trials and prospective cohort studies on nutrients, foods and food patterns and the risk of 10 major chronic diseases: coronary heart disease, stroke, heart failure, diabetes, breast cancer, colorectal cancer, lung cancer, chronic obstructive pulmonary disease, dementia and depression. The committee also selected three causal risk factors for cardiovascular diseases or diabetes: systolic blood pressure, low-density lipoprotein cholesterol and body weight. Findings were categorized as strong or weak evidence, inconsistent effects, too little evidence or effect unlikely for experimental and observational data separately. Next, the committee selected only findings with a strong level of evidence for deriving the guidelines. Convincing evidence was based on strong evidence from the experimental data either or not in combination with strong evidence from prospective cohort studies. Plausible evidence was based on strong evidence from prospective cohort studies only. A general guideline to eat a more plant food-based dietary pattern and limit consumption of animal-based food and 15 specific guidelines have been formulated. There are 10 new guidelines on legumes, nuts, meat, dairy produce, cereal products, fats and oils, tea, coffee and sugar-containing beverages. Three guidelines on vegetables, fruits, fish and alcoholic beverages have been sharpened, and the 2006 guideline on salt stayed the same. A separate guideline has been formulated on nutrient supplements. Completely food-based dietary guidelines can be derived in a systematic and transparent way. PMID:27049034

    Gardiner, Joseph C; Dorgan, Joanne F; Rosen, Cliff J; Velie, Ellen M

    2010-01-01

    Background: The insulin-like growth factor (IGF) system is associated with the adult diet and chronic disease. Childhood diet may influence chronic disease through its effect on the IGF system; however, there is limited information describing the dietary predictors of the IGF system in adolescents. Objective: We examined associations between dietary food intake [fat, protein (animal and vegetable), carbohydrate, lactose, dietary fiber, calcium, zinc, and sodium] and serum IGF-I, IGF binding protein 1 (IGFBP-1), IGF binding protein 3 (IGFBP-3), and the IGF-I:IGFBP-3 molar ratio in adolescent females. Design: One hundred fifty-nine adolescent females in the Dietary Intervention Study in Children (age range: 14–18 y; 0.2–6.3 y postmenarche) were included. The dietary intake was assessed via three 24-h dietary recalls. IGF-related biomarkers were determined by using radioimmunoassays. Associations between dietary intakes and biomarkers were assessed with Pearson's correlations and multivariable linear regression. Dietary intakes and biomarkers were logarithmically transformed; thus, β coefficients represented percentages. Results: In analyses adjusted for energy, age, and time since menarche, significant correlations (P < 0.05) were as follows: IGF-I with total protein, lactose, calcium, and sodium; IGFBP-3 with total fat (inverse), lactose, fiber, and calcium; IGF-I/IGFBP-3 with lactose and calcium; and IGFBP-1 with vegetable protein. In multivariable analyses, significant predictors of IGF-I were energy (β = 0.14, P < 0.05) and calcium (β = 0.14, P < 0.01), the significant predictor of IGFBP-3 was calcium (β = 0.07, P < 0.05), and significant predictors of IGFBP-1 were vegetable protein (β = 0.49, P < 0.05) and body mass index–for-age percentile (β = −0.01, P < 0.001). Conclusion: This study provides evidence that dietary intake affects IGF-related biomarkers—particularly elevated calcium with IGF-I and IGFBP-3 and elevated vegetable protein with

    Endothelial dysfunction with impaired bioavailability of nitric oxide (NO) is the hallmark in the development of cardiovascular disease. Endothelial dysfunction leads to atherosclerosis, characterized by chronic inflammation of the arterial wall and stepwise narrowing of the vessel lumen. Atherosclerosis causes deprivation of adequate tissue blood flow with compromised oxygen supply. To overcome this undersupply, remodeling of the vascular network is necessary to reconstitute and sustain tissue viability. This physiological response is often not sufficient and therapeutic angiogenesis remains an unmet medical need in critical limb ischemia or coronary artery disease. Feasible approaches to promote blood vessel formation are sparse. Administration of pro-angiogenic factors, gene therapy, or targeting of microRNAs has not yet entered the daily practice. Nitric oxide is an important mediator of angiogenesis that becomes limited under ischemic conditions and the maintenance of NO availability might constitute an attractive therapeutic target. Until recently it was unknown how the organism provides NO under ischemia. In recent years it could be demonstrated that NO can be formed independently of its enzymatic synthesis in the endothelium by reduction of inorganic nitrite under hypoxic conditions. Circulating nitrite derives from oxidation of NO or reduction of inorganic nitrate by commensal bacteria in the oral cavity. Intriguingly, nitrate is a common constituent of our everyday diet and particularly high concentrations are found in leafy green vegetables such as spinach, lettuce, or beetroot. Evidence suggests that dietary nitrate supplementation increases the regenerative capacity of ischemic tissue and that this effect may offer an attractive nutrition-based strategy to improve ischemia-induced revascularization. We here summarize and discuss the regenerative capacity of dietary nitrate on the vascular system. PMID:26516419

  14. Antitumor Immunity and Dietary Compounds

    Directory of Open Access Journals (Sweden)

    Annalise R. Smith

    2013-12-01

    Full Text Available The mechanisms by which natural dietary compounds exert their antitumor effects have been the focus of a large number of research efforts in recent years. Induction of apoptosis by inhibition of cell proliferative pathways is one of the common means of cell death employed by these dietary compounds. However, agents that can activate an antitumor immune response in addition to a chemotherapeutic effect may be useful adjuvants or alternative therapies for the treatment of cancer. The focus of this review is to highlight representative dietary compounds, namely Withania somnifera, Panax ginseng, curcumin and resveratrol with special emphasis on their antitumor immune mechanism of action. Each of these dietary compounds and their sources has a history of safe human use as food or in herbal medicine traditions, potentially making them ideal therapeutics. Here we report the recent advances in the cellular immune mechanisms utilized by these compounds to induce antitumor immunity. Taken together, these findings provide a new perspective for exploiting novel dietary compounds as chemoimmunotherapeutic anti-cancer agents.

    Dietary supplement use among athletes to enhance performance is proliferating as more individuals strive for obtaining that chemical competitive edge. As a result the concomitant use of dietary supplements containing performance-enhancing substances of those falling in the categories outlined in the current review, can also be expected to rise. This despite ever-increasing sophisticated analytical methodology techniques being used to assay dietary supplement and urine samples in doping laboratories. The reasons for this include that a variety of these chemical entities, many of them on the prohibited drug list of the WADA, are being produced on commercial scales in factories around the world (ephedrine and pseudoephedrine, sibutramine, methylhexaneamine, prohormones, 'classic' anabolic steroids, clenbuterol, peptide hormones etc.), aggressive marketing strategies are being employed by companies and these supplements can be easily ordered via e.g. the internet. It can also be anticipated that there will be an increase in the number of supplements containing 'designer' steroids and other 'newer' molecules. Chromatographic techniques combined with mass spectrometry leading to identification of molecular fragments and productions will assist in determining these substances. To prevent accidental doping, information regarding dietary supplements must be provided to athletes, coaches and sports doctors at all levels of competition. The risks of accidental doping via dietary supplement ingestion can be minimized by using 'safe' products listed on databases, e.g. such as those available in The Netherlands and Germany.

    2010-08-01

    Chronic pancreatitis results in exocrine and endocrine dysfunction, affecting normal digestion and absorption of nutrients. In individuals with chronic pancreatitis, nutrition status may be further affected by poor dietary intake, often related to alcoholism. However, some deficiencies may be overlooked, potentially leading to nutrition-related problems with bone health and fatigue. The aim of this article is to describe the deficiencies that occur and to propose an evidence-based algorithm for the nutrition assessment and treatment of patients with chronic pancreatitis.

  20. Dietary Fats and Metabolic Syndrome

    Directory of Open Access Journals (Sweden)

    2013-12-01

    Full Text Available The quantity and quality of fats consumed in the diet can have important effects on prevention and/or improvement clustering metabolic abnormalities of the metabolic syndrome. Fatty acids as food ingredients regulate cholesterol homeostasis and concentrations of blood lipoproteins, and affect the levels of other cardiometabolic risk factors, such as blood pressure, haemostasis, and body weight, through various mechanisms. There is convincing evidence that exchanging dietary saturated fat with monounsaturated fat produces beneficial effects on metabolic control, i.a. it lowers LDL-cholesterol concentrations, improves the postprandial lipid profile and lowers the blood pressure. Serum fatty acid composition mainly reflects dietary fat intake, but also endogenous fatty acid synthesis catalyzed by desaturases. Furthermore, high fat intake and serum fatty acid profile may influence the progression of obesity and insulin sensitivity. This review highlights current dietary guidance of fats quality recommendation in health and cardio metabolic risk.

    Full Text Available The prevalence of overweight and obesity and their associated metabolic disorders are considered a major threat to the public’s health. While several diet and exercise programs are available for weight loss and prevention of weight regain, progress is often slow and disappointing. Recently, natural bioactive phytochemicals present in foods have been discovered for their potential health benefit effects on the prevention of chronic disorders such as cancer, cardiovascular disease, inflammatory and metabolic diseases including obesity.Polyphenols are a class of naturally-occurring phytochemicals, of which some such as catechins, anthocynines, resveratrol and curcumin have been shown to modulate physiological and molecular pathways that are involved in energy metabolism, adiposity, and obesity. The potential in vivo, beneficial effects of these polyphenols on adiposity and obesity as complementary agents in the up-regulation of energy expenditure have emerged by investigating these compounds in cell cultures, animal models of obesity and in some human clinical and epidemiological studies. In this brief review, the efficacy of the above-named polyphenols and their potential efficacy to modulate obesity and some associated disorders are discussed.

    2015-10-28

    Nonalcoholic fatty liver disease (NAFLD) has been identified as one of the most prevalent chronic liver disease in adults and children populations. NAFLD is usually associated with the metabolic syndrome (MS), which is chiefly related to insulin resistance and its consequences. Insulin resistance has a crucial role in the pathogenesis of hepatic steatosis and potentially nonalcoholic steatohepatitis (NASH). Because of the contemporary epidemics of MS and obesity, the burden of NAFLD is also expected to rise. Unhealthy diets, such as the so-called western diet, are enriched in fructose, trans-fatty acids and saturated fat and seem to be associated with the development of NAFLD. In human studies, certain dietary sugars, particularly fructose, are used as a substrate for lipogenesis leading to hepatic fatty infiltration, inflammation, and possibly fibrosis. Other investigations have shown that fat consumption especially cholesterol and trans/saturated fatty acids are also steatogenic and seem to increase visceral adiposity. The identification of specific dietary components that favor the development of NASH could be important for the management of this disorder. This review focuses on the effects of different dietary approaches to prevent and treat NAFLD emphasizing the macronutrients and energy composition. PMID:26523205

    The physiological functions of dietary fiber and its role in health promotion and risk reduction of some chronic diseases has been well documented. In the present investigation, the effect of three dietary fiber sources, oats (OA), barley (BA) and psyllium husk (PH) on glucose adsorption, diffusion and starch hydrolysis were studied using in vitro techniques by simulating gastrointestinal conditions and compared with the commercial dietary fiber sources wheat bran (WB), acarbose (ACB) and guar gum (GG). The glucose binding capacity of all the samples was higher than WB and ACB at 5 mM concentration. In all the samples, the diffusion of glucose was directly proportional to the time and diffusion rate was significantly lower (p ≤ 0.01) in the system containing various samples compared to control. Glucose dialysis retardation index (GDRI) was 100 for OA, BA and PH at 60 min, at 120 min the maximal GDRI was in PH. Whereas; WB and ACB exhibited maximal GDRI at 180 and 240 min. All of these mechanisms might create a concerted function in lowering the rate of glucose absorption and as a result, decrease the postprandial hyperglycemia. PMID:23572748

Unhealthy diets, such as the so-called western diet, are enriched in fructose, trans-fatty acids and saturated fat and seem to be associated with the development of NAFLD. In human studies, certain dietary sugars, particularly fructose, are used as a substrate for lipogenesis leading to hepatic fatty infiltration, inflammation, and possibly fibrosis. Other investigations have shown that fat consumption especially cholesterol and trans/saturated fatty acids are also steatogenic and seem to increase visceral adiposity. The identification of specific dietary components that favor the development of NASH could be important for the management of this disorder. This review focuses on the effects of different dietary approaches to prevent and treat NAFLD emphasizing the macronutrients and energy composition.

    Full Text Available Chronic nutrient overload accelerates the onset of several aging-related diseases reducing life expectancy. Although the mechanisms by which overnutrition affects metabolic processes in many tissues are known, its role on BAT physiology is still unclear. Herein, we investigated the mitochondrial responses in BAT of female mice exposed to high fat diet (HFD at different steps of life. Although adult mice showed an unchanged mitochondrial amount, both respiration and OxPHOS subunits were strongly affected. Differently, offspring pups exposed to HFD during pregnancy and lactation displayed reduced mitochondrial mass but high oxidative efficiency that, however, resulted in increased bioenergetics state of BAT rather than augmented uncoupling respiration. Interestingly, the metabolic responses triggered by HFD were accompanied by changes in mitochondrial dynamics characterized by decreased content of the fragmentation marker Drp1 both in mothers and offspring pups. HFD-induced inactivation of the FoxO1 transcription factor seemed to be the up-stream modulator of Drp1 levels in brown fat cells. Furthermore, HFD offspring pups weaned with normal diet only partially reverted the mitochondrial dysfunctions caused by HFD. Finally these mice failed in activating the thermogenic program upon cold exposure. Collectively our findings suggest that maternal dietary fat overload irreversibly commits BAT unresponsiveness to physiological stimuli such as cool temperature and this dysfunction in the early stage of life might negatively modulates health and lifespan.

    Full Text Available Oxidative stress promotes DNA damage and may also contribute to the development of chronic disease, including type 2 diabetes (T2DM, neurodegenerative diseases, cardiovascular diseases and cancer. Oxidative stress is a result of an imbalance between the production and accumulation of reactive species and the organism´s capacity to manage those using endogenous and exogenous antioxidants. Exogenous antioxidants obtained from the diet, mainly vitamin C, vitamin E, zinc, selenium and carotenoids have an important role in reducing oxidative stress and also DNA damage. Endogenous antioxidants include the enzymes catalase, glutathione peroxidase and superoxide dismutase. Nutrigenetics is a field of science that examines the interactions between diet and genetic variation. Individual genetic variation can affect proteins involved in the uptake, utilization and metabolism of dietary antioxidants. It may alter their serum levels and subsequent contribution to modulation of oxidative stress. The elucidation of interaction between genetic variations and antioxidant status may have important implications for public health through the identification of individuals and populations who could benefit from dietary intervention and supplementation with antioxidants. A greater understanding of which antioxidants could promote more protection and increase DNA repair may be important as a strategy to avoid the earlier development of chronic diseases.

  19. Dietary nutraceuticals as novel radioprotectors

    International Nuclear Information System (INIS)

    There is long standing need to protect humans from the deleterious effects of ionizing radiation in the event of radiation related calamities or otherwise. Various dietary ingredients have formed an integral part of daily human diets. Most of the ingredients used in the Indian diet possess medicinal properties. However, little attention has been paid to screen the radioprotective ability of dietary ingredients. It is possible that use of dietary agents could protect against the deleterious effects of ionizing radiations more effectively than other exotic synthetic agents simply because they are from natural biological sources, and may be more biocompatible than any other synthetic counterparts. Their acceptance for therapeutic purpose will be acceptable as they are part of daily human diets and do not have any known toxicity. This has been a stimulation to investigate the radioprotective ability of certain dietary ingredients including naringin and mangiferin in vivo and in vitro using micronuclei or survival assays. Treatment of mice with various doses of naringin or mangiferin reduced the symptoms of radiation-induced sickness including listlessness, irritability, lethargy, reduction in food and water intake, diarrhea, lacrimation, facial edema weight loss, emaciation, and epilation. Mice receiving various doses of naringin reduced the radiation-induced micronuclei formation and chromosome aberrations in bone marrow. Likewise, treatment of human peripheral blood lymphocytes with various concentrations of mangiferin reduced the radiation-induced DNA damage. The putative mechanisms of radioprotection are free radical scavenging, increased GSH accompanied by reduced lipid peroxidation. The use of dietary ingredients for radioprotection shall be encouraged as they are consumed daily and toxic implications are negligible. (author)

    2012-01-01

    Full Text Available There is consistent evidence linking excessive dietary sodium intake to risk factors for cardiovascular disease and chronic kidney disease (CKD progression in CKD patients; however, additional research is needed. In research trials and clinical practice, implementing and monitoring sodium intake present significant challenges. Epidemiological studies have shown that sodium intake remains high, and intervention studies have reported varied success with participant adherence to a sodium-restricted diet. Examining barriers to sodium restriction, as well as factors that predict adherence to a low sodium diet, can aid researchers and clinicians in implementing a sodium-restricted diet. In this paper, we critically review methods for measuring sodium intake with a specific focus on CKD patients, appraise dietary adherence, and factors that have optimized sodium restriction in key research trials and discuss barriers to sodium restriction and factors that must be considered when recommending a sodium-restricted diet.

    Full Text Available Abstract The subjective nature of self-reported dietary intake assessment methods presents numerous challenges to obtaining accurate dietary intake and nutritional status. This limitation can be overcome by the use of dietary biomarkers, which are able to objectively assess dietary consumption (or exposure without the bias of self-reported dietary intake errors. The need for dietary biomarkers was addressed by the Institute of Medicine, who recognized the lack of nutritional biomarkers as a knowledge gap requiring future research. The purpose of this article is to review existing literature on currently available dietary biomarkers, including novel biomarkers of specific foods and dietary components, and assess the validity, reliability and sensitivity of the markers. This review revealed several biomarkers in need of additional validation research; research is also needed to produce sensitive, specific, cost-effective and noninvasive dietary biomarkers. The emerging field of metabolomics may help to advance the development of food/nutrient biomarkers, yet advances in food metabolome databases are needed. The availability of biomarkers that estimate intake of specific foods and dietary components could greatly enhance nutritional research targeting compliance to national recommendations as well as direct associations with disease outcomes. More research is necessary to refine existing biomarkers by accounting for confounding factors, to establish new indicators of specific food intake, and to develop techniques that are cost-effective, noninvasive, rapid and accurate measures of nutritional status.

  10. Calcium binding by dietary fibre

    International Nuclear Information System (INIS)

    Dietary fibre from plants low in phytate bound calcium in proportion to its uronic-acid content. This binding by the non-cellulosic fraction of fibre reduces the availability of calcium for small-intestinal absorption, but the colonic microbial digestion of uronic acids liberates the calcium. Thus the ability to maintain calcium balance on high-fibre diets may depend on the adaptive capacity on the colon for calcium. (author)

    Dietary micronutrient deficiencies (MNDs) are widespread, yet their prevalence can be difficult to assess. Here, we estimate MND risks due to inadequate intakes for seven minerals in Africa using food supply and composition data, and consider the potential of food-based and agricultural interventions. Food Balance Sheets (FBSs) for 46 countries were integrated with food composition data to estimate per capita supply of calcium (Ca), copper (Cu), iron (Fe), iodine (I), magnesium (Mg), selenium (Se) and zinc (Zn), and also phytate. Deficiency risks were quantified using an estimated average requirement (EAR) 'cut-point' approach. Deficiency risks are highest for Ca (54% of the population), followed by Zn (40%), Se (28%) and I (19%, after accounting for iodized salt consumption). The risk of Cu (1%) and Mg (risks are generally lower in the north and west of Africa. Multiple MND risks are high in many countries. The population-weighted mean phytate supply is 2770 mg capita(-1) day(-1). Deficiency risks for Fe are lower than expected (5%). However, 'cut-point' approaches for Fe are sensitive to assumptions regarding requirements; e.g. estimates of Fe deficiency risks are 43% under very low bioavailability scenarios consistent with high-phytate, low-animal protein diets. Fertilization and breeding strategies could greatly reduce certain MNDs. For example, meeting HarvestPlus breeding targets for Zn would reduce dietary Zn deficiency risk by 90% based on supply data. Dietary diversification or direct fortification is likely to be needed to address Ca deficiency risks. PMID:24524331

  12. Dietary Supplementations as Neuroprotective Therapies: Focus on NT-020 Diet Benefits in a Rat Model of Stroke

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available Stroke remains the number one cause of disability in the adult population. Despite scientific progress in our understanding of stroke pathology, only one treatment (tissue plasminogen activator or tPA is able to afford benefits but to less than 3% of ischemic stroke patients. The development of experimental dietary supplement therapeutics designed to stimulate endogenous mechanisms that confer neuroprotection is likely to open new avenues for exploring stroke therapies. The present review article evaluates the recent literature supporting the benefits of dietary supplementation for the therapy of ischemic stroke. This article focuses on discussing the medical benefits of NT-020 as an adjunct agent for stroke therapy. Based on our preliminary data, a pre-stroke treatment with dietary supplementation promotes neuroprotection by decreasing inflammation and enhancing neurogenesis. However, we recognize that a pre-stroke treatment holds weak clinical relevance. Thus, the main goal of this article is to provide information about recent data that support the assumption of natural compounds as neuroprotective and to evaluate the therapeutic effects of a dietary supplement called NT-020 as in a stroke model. We focus on a systematic assessment of practical treatment parameters so that NT-020 and other dietary supplementations can be developed as an adjunct agent for the prevention or treatment of chronic diseases. We offer rationale for determining the optimal dosage, therapeutic window, and mechanism of action of NT-020 as a dietary supplement to produce neuroprotection when administered immediately after stroke onset. We highlight our long-standing principle in championing both translational and basic science approaches in an effort to fully reveal the therapeutic potential of NT-020 as dietary supplementation in the treatment of stroke. We envision dietary supplementation as an adjunct therapy for stroke at acute, subacute, and even chronic periods.

    Some plant-based diets lower the cardiometabolic risks and prevalence of hypertension. New evidence implies a role for the transient receptor potential vanilloid 1 (TRPV1) cation channel in the pathogenesis of cardiometabolic diseases. Little is known about impact of chronic TRPV1 activation on the...... regulation of vascular function and blood pressure. Here we report that chronic TRPV1 activation by dietary capsaicin increases the phosphorylation of protein kinase A (PKA) and eNOS and thus production of nitric oxide (NO) in endothelial cells, which is calcium dependent.

    Inflammatory bowel disease (IBD) including ulcerative colitis and Crohn's disease are chronic relapsing and remitting chronic diseases for which there is no cure. The treatment of IBD frequently requires immunosuppressive and biologic therapies which carry an increased risk of infections and possible malignancy. There is a continued search for safer and more natural therapies in the treatment of IBD. This review aims to summarize the most current literature on the use of dietary supplements for the treatment of IBD. Specifically, the efficacy and adverse effects of vitamin D, fish oil, probiotics, prebiotics, curcumin, Boswellia serrata, aloe vera and cannabis sativa are reviewed. PMID:26561079

    Full Text Available Chronic urticaria (CU is a disturbing allergic condition of the skin. Although frequently benign, it may sometimes be a red flag sign of a serious internal disease. A multitude of etiologies have been implicated in the causation of CU, including physical, infective, vasculitic, psychological and idiopathic. An autoimmune basis of most of the ′idiopathic′ forms is now hypothesized. Histamine released from mast cells is the major effector in pathogenesis and it is clinically characterized by wheals that have a tendency to recur. Laboratory investigations aimed at a specific etiology are not always conclusive, though may be suggestive of an underlying condition. A clinical search for associated systemic disease is strongly advocated under appropriate circumstances. The mainstay of treatment remains H1 antihistaminics. These may be combined with complementary pharmacopeia in the form of H2 blockers, doxepin, nifedipine and leukotriene inhibitors. More radical therapy in the form of immunoglobulins, plasmapheresis and cyclophosphamide may be required for recalcitrant cases. Autologous transfusion and alternative remedies like acupuncture have prospects for future. A stepwise management results in favorable outcomes. An update on CU based on our experience with patients at a tertiary care centre is presented.

    Full Text Available Given the public health importance of improving dietary behavior in chronic disease prevention in low- and middle-income countries it is crucial to understand the factors influencing dietary behavior in these settings. This study tested the validity of a conceptual framework linking individual and environmental factors to dietary behavior among Ecuadorian adolescents aged 10-16 years.A cross-sectional survey was conducted in 784 school-going Ecuadorian adolescents in urban and rural Southern Ecuador. Participants provided data on socio-economic status, anthropometry, dietary behavior and its determining factors. The relationships between individual (perceived benefits and barriers, self-efficacy, habit strength, and a better understanding of healthy food and environmental factors (physical environment: accessibility to healthy food; social environment: parental permissiveness and school support, and their association with key components of dietary behavior (fruit and vegetables, sugary drinks, breakfast, and unhealthy snack intake were assessed using structural equation modeling.The conceptual model performed well for each component of eating behavior, indicating acceptable goodness-of-fit for both the measurement and structural models. Models for vegetable intake and unhealthy snacking showed significant and direct effects of individual factors (perceived benefits. For breakfast and sugary drink consumption, there was a direct and positive association with socio-environmental factors (school support and parental permissiveness. Access to healthy food was associated indirectly with all eating behaviors (except for sugary drink intake and this effect operated through socio-environmental (parental permissiveness and school support and individual factors (perceived benefits.Our study demonstrated that key components of adolescents' dietary behaviors are influenced by a complex interplay of individual and environmental factors.

    Objective Given the public health importance of improving dietary behavior in chronic disease prevention in low- and middle-income countries it is crucial to understand the factors influencing dietary behavior in these settings. This study tested the validity of a conceptual framework linking individual and environmental factors to dietary behavior among Ecuadorian adolescents aged 10–16 years. Methods A cross-sectional survey was conducted in 784 school-going Ecuadorian adolescents in urban and rural Southern Ecuador. Participants provided data on socio-economic status, anthropometry, dietary behavior and its determining factors. The relationships between individual (perceived benefits and barriers, self-efficacy, habit strength, and a better understanding of healthy food) and environmental factors (physical environment: accessibility to healthy food; social environment: parental permissiveness and school support), and their association with key components of dietary behavior (fruit and vegetables, sugary drinks, breakfast, and unhealthy snack intake) were assessed using structural equation modeling. Results The conceptual model performed well for each component of eating behavior, indicating acceptable goodness-of-fit for both the measurement and structural models. Models for vegetable intake and unhealthy snacking showed significant and direct effects of individual factors (perceived benefits). For breakfast and sugary drink consumption, there was a direct and positive association with socio-environmental factors (school support and parental permissiveness). Access to healthy food was associated indirectly with all eating behaviors (except for sugary drink intake) and this effect operated through socio-environmental (parental permissiveness and school support) and individual factors (perceived benefits). Conclusion Our study demonstrated that key components of adolescents’ dietary behaviors are influenced by a complex interplay of individual and

    Although dietary diversity is universally recognized as a key component of healthy diets, there is still a lack of consensus on how to measure and operationalize it. This paper focuses on the issues of dietary diversity in developing countries. It also draws upon experience from developed countries to address the following questions: 1. How is dietary diversity conceptualized, operationalized, and measured, and how does it relate operationally to dietary quality? 2. Is there an association be...

    Full Text Available Background: One of the adipokines mostly secreted from adipose tissue is adiponectin. Adiponectin is well known as the anti-diabetic, anti-obesity and cardio-protective factor. Present study focused on the review the previous studies about relationship between adherence to healthy dietary pattern, independent of one or two special dietary components, and concentration of adiponectin. Materials and Methods: We searched in PubMed search engine from 2003 to July 2014 using the following key words: Healthy dietary pattern, mediterranean dietary pattern, dietary pattern, diet intervention and adiponectin and adipokines. Then, we recruited 10 articles to review in the present study. Results: Cohort studies that are examined this relationship among women showed the strong positive association in this regard. According to cross-sectional studies adherence to healthy dietary pattern like Mediterranian intervention with moderate weight loss had a positive association with concentration of adiponectin. Conclusion: It seems that adherents to the healthy dietary patterns have great levels of circulating adiponectin. However, it is not clear that whether the separate components of healthy dietary patterns like good sources of fats or protein or fibers mostly have important roles in these beneficial effects of such dietary patterns or not.

  12. Trends in dietary patterns of Latin American populations

    Full Text Available It is important to characterize the level and magnitude of changes in food consumption patterns in Latin American populations as they undergo demographic and developmental transitions because of the effects of such changes on the development and progression of chronic diseases. This paper examines trends in food intake across regions in Latin America. Although trends in apparent food consumption differ in magnitude and timing, the overall patterns of change are remarkably consistent. Intakes of total fat, animal products, and sugar are increasing, even while there have been rapid declines in the intake of cereals, fruit, and some vegetables. The costs of the increased prevalence of chronic disease associated with these dietary changes are already affecting health systems still coping with malnutrition and infectious disease. Because this pattern of change is predictable, it is important to learn from the experiences gained in countries that are more advanced in the transition. Efforts to educate the population on the importance of a healthy diet and to issue policies to improve the availability of a healthy food supply can help to reduce the rapid escalation of obesity and chronic diseases.

  16. Health effects of dietary phospholipids

    2012-01-01

    Full Text Available Abstract Beneficial effects of dietary phospholipids (PLs have been mentioned since the early 1900's in relation to different illnesses and symptoms, e.g. coronary heart disease, inflammation or cancer. This article gives a summary of the most common therapeutic uses of dietary PLs to provide an overview of their approved and proposed benefits; and to identify further investigational needs. From the majority of the studies it became evident that dietary PLs have a positive impact in several diseases, apparently without severe side effects. Furthermore, they were shown to reduce side effects of some drugs. Both effects can partially be explained by the fact that PL are highly effective in delivering their fatty acid (FA residues for incorporation into the membranes of cells involved in different diseases, e.g. immune or cancer cells. The altered membrane composition is assumed to have effects on the activity of membrane proteins (e.g. receptors by affecting the microstructure of membranes and, therefore, the characteristics of the cellular membrane, e.g. of lipid rafts, or by influencing the biosynthesis of FA derived lipid second messengers. However, since the FAs originally bound to the applied PLs are increased in the cellular membrane after their consumption or supplementation, the FA composition of the PL and thus the type of PL is crucial for its effect. Here, we have reviewed the effects of PL from soy, egg yolk, milk and marine sources. Most studies have been performed in vitro or in animals and only limited evidence is available for the benefit of PL supplementation in humans. More research is needed to understand the impact of PL supplementation and confirm its health benefits.

    2016-08-01

    The daily requirement of a 70-kg male for creatine is about 2 g; up to half of this may be obtained from a typical omnivorous diet, with the remainder being synthesized in the body Creatine is a carninutrient, which means that it is only available to adults via animal foodstuffs, principally skeletal muscle, or via supplements. Infants receive creatine in mother's milk or in milk-based formulas. Vegans and infants fed on soy-based formulas receive no dietary creatine. Plasma and muscle creatine levels are usually somewhat lower in vegetarians than in omnivores. Human intake of creatine was probably much higher in Paleolithic times than today; some groups with extreme diets, such as Greenland and Alaskan Inuit, ingest much more than is currently typical. Creatine is synthesized from three amino acids: arginine, glycine and methionine (as S-adenosylmethionine). Humans can synthesize sufficient creatine for normal function unless they have an inborn error in a creatine-synthetic enzyme or a problem with the supply of substrate amino acids. Carnivorous animals, such as lions and wolves, ingest much larger amounts of creatine than humans would. The gastrointestinal tract and the liver are exposed to dietary creatine in higher concentrations before it is assimilated by other tissues. In this regard, our observations that creatine supplementation can prevent hepatic steatosis (Deminice et al. J Nutr 141:1799-1804, 2011) in a rodent model may be a function of the route of dietary assimilation. Creatine supplementation has also been reported to improve the intestinal barrier function of the rodent suffering from inflammatory bowel disease. PMID:26874700

  3. Utilization of dietary glucose in the metabolic syndrome

    Directory of Open Access Journals (Sweden)

    Alemany Marià

    2011-10-01

    Full Text Available Abstract This review is focused on the fate of dietary glucose under conditions of chronically high energy (largely fat intake, evolving into the metabolic syndrome. We are adapted to carbohydrate-rich diets similar to those of our ancestors. Glucose is the main energy staple, but fats are our main energy reserves. Starvation drastically reduces glucose availability, forcing the body to shift to fatty acids as main energy substrate, sparing glucose and amino acids. We are not prepared for excess dietary energy, our main defenses being decreased food intake and increased energy expenditure, largely enhanced metabolic activity and thermogenesis. High lipid availability is a powerful factor decreasing glucose and amino acid oxidation. Present-day diets are often hyperenergetic, high on lipids, with abundant protein and limited amounts of starchy carbohydrates. Dietary lipids favor their metabolic processing, saving glucose, which additionally spares amino acids. The glucose excess elicits hyperinsulinemia, which may derive, in the end, into insulin resistance. The available systems of energy disposal could not cope with the excess of substrates, since they are geared for saving not for spendthrift, which results in an unbearable overload of the storage mechanisms. Adipose tissue is the last energy sink, it has to store the energy that cannot be used otherwise. However, adipose tissue growth also has limits, and the excess of energy induces inflammation, helped by the ineffective intervention of the immune system. However, even under this acute situation, the excess of glucose remains, favoring its final conversion to fat. The sum of inflammatory signals and deranged substrate handling induce most of the metabolic syndrome traits: insulin resistance, obesity, diabetes, liver steatosis, hyperlipidemia and their compounded combined effects. Thus, a maintained excess of energy in the diet may result in difficulties in the disposal of glucose, eliciting

    Full Text Available Abstract The aim of this work is to identify major food sources and dietary constituents of Senegalese adults. We conducted a cross-sectional study, using a single 24-hour dietary recall interview. Foods were classified into food groups based on similarities in nutrient content or use. Food groups included foods consumed individually, or as part of food mixtures such as stews, soups, or sandwiches. Median consumption (amount/day of each food was determined and examined by relevant subgroups. Participants were 50 healthy Senegalese men, aged 20-62 years recruited at the Hôpital Général de Grand Yoff in Dakar, Senegal and from Sendou village, a rural area outside Dakar. A total of 90 foods and beverages were identified and classified into 11 groups. Sixty-five percent of foods identified could be classified as meats, grains, or fruits/vegetables. Fruits and vegetables comprised 42% (38/90 of all foods; meats 12% (11/90; and grains 11% (10/90. Sauces (6%, 5/90, sweets (4%, 4/90, and desserts (4%, 4/90 were also reported. The most common fruits/vegetables reported were potato, carrot, mango, and lettuce; commonly reported grains were bread and rice; and commonly reported meats were fish, beef, and ox. There were no differences in reported daily intake of each food by age, ethnicity, education, or residence. Most foods reported were traditional to the Senegalese diet, despite the increasing availability of Western foods in Senegal.

    In this paper a mathematical model for human dietary exposure to polychlorinated biphenyls is postulated, based on the calculation of human exposure factors to PCBs via different members of the terrestrial food chain. On the basis of postulated model and experimental values for the atmospheric and soil concentration of PCBs it is possible to calculate the average daily exposure of a human organism to these ubiquitous environmental toxicants, which represent a constant threat to human health due to various chronic, developmental and genetic effects. Proposed model is the contribution to the development of exposure analysis, which is a part of a complex process of risk assessment, which gains its importance in the current situation of rapid development of industry and technology and the existence of innumerable anthropogenic hazardous chemicals.

Objectives: This study characterized dietary patterns in adolescents in urban area located in northeast of Brazil, relating it to the markers of a healthy diet. Methods: A cross-sectional study used two 24-hour recalls to assess dietary intake in 430 public school students from Natal-RN, Brazil. Principal component analysis was used to derive dietary patterns according to consumption of food based on weight (grams, energy (Kcal, or fiber (grams. These models resulted in a number of different main components, 7, 8 and 4, respectively (cumulative variance >70%; factor loadings >0.4. The association between independent variables and the factor scores of all components obtained was determined by the Prevalence Ratio (CI 95%. Results: The dietary patterns derived were: (1 Pure Traditional Food System, the highly representative pattern in young adolescents and the first component of the analytical models, (2 Combined and Risk Food System; extraction of total food weight and energy revealed markers of unhealthy diets based on high sugar, saturated fat, and salt consumption, and (3 Modified Traditional Food System represented by fiber; pattern 1 was observed within this model too. The associations observed, predominantly from the TFSm pattern, distinguished by sex, age and nutritional status. Conclusions: Patterns 1 and 3 are characterized by preserved regional food practices that prevent chronic disease, whereas pattern 2 is characterized by health risks. These inter-sectorial findings should be considered in the development of health care policies for children and adolescents.

    2013-11-01

    Diet-related chronic diseases are major public health concerns in England and the associated costs to the National Health Service and society are considerable. Poor diet and other lifestyle factors are estimated to account for about one-third of all deaths from CVD in England. UK dietary recommendations were set by the Committee on Medical Aspects of Food Policy and are now set by the Scientific Advisory Committee on Nutrition. For cardiovascular health, dietary recommendations are set for nutrients (saturated fat, trans-fat and carbohydrates), foods (fruits, vegetables and oily fish) and salt. The National Diet and Nutrition Survey demonstrates that the majority of the UK population have poor diets. Average intakes of saturated fat and salt are above recommendations while fruit, vegetables, fibre and oily fish are below recommendations. The Department of Health in England is committed to working to improve diet and lifestyle. Current work includes the Public Health Responsibility Deal, under which organisations pledge to increase fruits and vegetables and reduce levels of salt, trans-fat and energy in manufactured foods and menus, the provision of information to help improve food choice through better food labels and provision of information, including a NHS Choices website and the social marketing campaign Change4Life.

    Dietary supplements (DS) are easily available and increasingly used, and adverse hepatic reactions have been reported following their intake. To critically review the literature on liver injury because of DSs, delineating patterns and mechanisms of injury and to increase the awareness towards this cause of acute and chronic liver damage. Studies and case reports on liver injury specifically because of DSs published between 1990 and 2010 were searched in the PubMed and EMBASE data bases using the terms 'dietary/nutritional supplements', 'adverse hepatic reactions', 'liver injury'; 'hepatitis', 'liver failure', 'vitamin A' and 'retinoids', and reviewed for yet unidentified publications. Significant liver injury was reported after intake of Herbalife and Hydroxycut products, tea extracts from Camellia sinensis, products containing usnic acid and high contents of vitamin A, anabolic steroids and others. No uniform pattern of hepatotoxicity has been identified and severity may range from asymptomatic elevations of serum liver enzymes to hepatic failure and death. Exact estimates on how frequent adverse hepatic reactions occur as a result of DSs cannot be provided. Liver injury from DSs mimicking other liver diseases is increasingly recognized. Measures to reduce risk include tighter regulation of their production and distribution and increased awareness of users and professionals of the potential risks. PMID:21457433

    Full Text Available Maternal nutritional status during pregnancy will affect the outcomes for the mother and the baby. Many analyses of the relationship between diet and outcome are often based on a single or a few food items or nutrients. However, foods are not consumed in isolation and dietary patterns can be used to assess the whole diet consumed. The use of dietary pattern analysis to understand nutritional intake and pregnancy outcome is becoming more and more popular. Many published studies have showed the association between maternal dietary patterns and pregnancy outcome. This review examined articles about the relationship between maternal dietary patterns and pregnancy outcome. As a modifiable factor, dietary patterns may be more applicable to clinical and pregnant health interventions.

    Dietary patterns analysis is an emerging area of research. Identifying distinct patterns within a large dietary survey can give a more accurate representation of what people are eating. Furthermore, it allows researchers to analyse relationships between non-communicable diseases (NCD) and complete diets rather than individual food items or nutrients. However, few such studies have been conducted in developing countries including India, where the population has a high burden of diabetes and CVD. We undertook a systematic review of published and grey literature exploring dietary patterns and relationships with diet-related NCD in India. We identified eight studies, including eleven separate models of dietary patterns. Most dietary patterns were vegetarian with a predominance of fruit, vegetables and pulses, as well as cereals; dietary patterns based on high-fat, high-sugar foods and more meat were also identified. There was large variability between regions in dietary patterns, and there was some evidence of change in diets over time, although no evidence of different diets by sex or age was found. Consumers of high-fat dietary patterns were more likely to have greater BMI, and a dietary pattern high in sweets and snacks was associated with greater risk of diabetes compared with a traditional diet high in rice and pulses, but other relationships with NCD risk factors were less clear. This review shows that dietary pattern analyses can be highly valuable in assessing variability in national diets and diet-disease relationships. However, to date, most studies in India are limited by data and methodological shortcomings. PMID:27146890

    Dietary and lifestyle changes in Mexico have been linked to an increase in chronic diseases such as obesity and cardiovascular disease. Important dietary changes such as an increase in the consumption of energy-dense foods (high in oils, animal or processed fats, and sugars) have been recently reported. The objective of this study was to identify how key dietary energy sources correlated with other indexes of cardiovascular disease in a Mexican school-age population. From 2004 to 2006, a convenience sample (n=228) of 9- to 13-year-olds, 48.2% girls and 51.8% boys, from three public urban schools were included. Anthropometric, blood pressure, and dietary assessment (two multiple pass 24-hour recalls) were done. More than half of children did not meet the fruit and vegetable recommended intake. High-fat dairy foods (14% of total energy intake), refined carbohydrates (13.5%), red/processed meat (8.5%), added sugars/desserts (7%), corn tortilla (6.5%), and soft drinks/sweetened beverages (5%) were the highest dietary energy sources consumed. In a subgroup of children (n=185), a fasting blood sample was collected for biochemical analysis. A positive association was observed between glucose and diastolic blood pressure with the intake of soft drinks/sweetened beverages, insulin concentrations and the intake of white bread, and triglyceride concentrations with the intake of added fats. Unhealthful dietary energy sources are frequently consumed by these children. Culturally competent nutrition counseling should be offered to Mexican-American children and their families with a significant risk of cardiovascular disease. Efforts should be made to design and implement nutrition education and health promotion strategies in schools. PMID:20102853

    Crude lecithin, a mixture of mainly phospholipids, potentially helps to increase the systemic availability of dietary omega-3 polyunsaturated fatty acids (n-3 PUFA), such as docosahexaenoic acid (DHA). Nevertheless, no clear data exist on the effects of prolonged combined dietary supplementation of DHA and lecithin on RBC and plasma PUFA levels. In the current experiments, levels of DHA and choline, two dietary ingredients that enhance neuronal membrane formation and function, were determined in plasma and red blood cells (RBC) from rats after dietary supplementation of DHA-containing oils with and without concomitant dietary supplementation of crude lecithin for 2-3 weeks. The aim was to provide experimental evidence for the hypothesized additive effects of dietary lecithin (not containing any DHA) on top of dietary DHA on PUFA levels in plasma and RBC. Dietary supplementation of DHA-containing oils, either as vegetable algae oil or as fish oil, increased DHA, eicosapentaenoic acid (EPA), and total n-3 PUFA, and decreased total omega-6 PUFA levels in plasma and RBC, while dietary lecithin supplementation alone did not affect these levels. However, combined dietary supplementation of DHA and lecithin increased the changes induced by DHA supplementation alone. Animals receiving a lecithin-containing diet also had a higher plasma free choline concentration as compared to controls. In conclusion, dietary DHA-containing oils and crude lecithin have synergistic effects on increasing plasma and RBC n-3 PUFA levels, including DHA and EPA. By increasing the systemic availability of dietary DHA, dietary lecithin may increase the efficacy of DHA supplementation when their intake is combined. PMID:27038174

    2016-05-01

    Full Text Available The low-grade inflammation observed in obesity is a risk factor for cardiovascular diseases and insulin resistance. Among factors triggering such inflammation, recent works revealed the role of bacterial lipopolysaccharides (LPS, so-called endotoxins. LPS are naturally present in the gut via the intestinal microbiota. Recent studies show that they can induce in plasma a metabolic endotoxemia after the consumption of unbalanced hyperlipidic meals. This article reviews recent knowledge gained on the role of intestinal lipid absorption and the composition of dietary lipids on: (i the induction of metabolic endotoxemia, (ii the types of plasma transporters of LPS and (iii associated low-grade inflammation. Notably, lipids are present in foods under various physicochemical structures and notably in emulsified form. Our recent works reveal that such structure and the type of emulsifier can modulate postprandial lipemia; recent results on the possible consequences on metabolic endotoxemia will be discussed.

    Dietary intake provides valuable insights for mounting intervention programs for prevention of disease. With growing concern for adolescent obesity, the need to accurately measure diet becomes imperative. Assessment among adolescents is problematic as this group has irregular eating patterns and have less enthusiasm for recording food intake. Preliminary studies among adolescents suggest that innovative use of technology may improve the accuracy of diet information from young people. In this paper, we propose a novel food record method using a mobile device that will provide an accurate account of daily food and nutrient intake among adolescents. Our approach includes the use of image analysis tools for identification and quantification of food consumption. Images obtained before and after food is consumed can be used to estimate the diet of an individual. In this paper we describe our initial results and indicate the potential of the proposed system.

  20. Refeeding hypertension in dietary obesity

    International Nuclear Information System (INIS)

    A novel model of nutritionally induced hypertension in the rat is described. Dietary obesity was produced by providing sweet milk in addition to regular chow, which elicited a 52% increase in caloric intake. Despite 54% greater body weight gain and 139% heavier retroperitoneal fat pads, 120 days of overfeeding failed to increase systolic pressure in the conscious state or mean arterial pressure under urethan anesthesia. In contrast, mild hypertension developed in intermittantly fasted obese animals. The first 4-day supplemented fast was initiated 4 wk after the introduction of sweet milk, when the animals were 47 g overweight relative to chow-fed controls. Thereafter, 4 days of starvation were alternated with 2 wk of refeeding for a total of 4 cycles. A rapid fall in systolic blood pressure accompanied the onset of supplemented fasting and was maintained thereafter. With refeeding, blood pressure rose precipitously, despite poststarvation anorexia. Blood pressure tended to rise slightly over the remainder of the realimentation period. After the 4th supplemented fast, hypertension was sustained during 30 days of refeeding. Cumulative caloric intake in starved-refed rats fell within 2% of that in chow-fed controls. Refeeding hypertension appeared to be due to increased sympathetic nervous activity, since (1) cardiac β-adrenergic receptors were downregulated, as indicated by a 40% decrease in the maximum binding of [3H]dihydroalpranolol; and (2) the decrease in heart rate as a result of β-blockade was enhanced. Refeeding hypertension in the dietary obese rat may be a potential animal model for some forms of human obesity-related hypertension

  1. Dietary carbohydrates and endurance exercise.

    1985-05-01

    Antecedent diet can greatly influence both substrate utilization during exercise and exercise performance itself. A number of studies have convincingly demonstrated that short-term (three to seven days) adaptation to a low carbohydrate diet results in greatly reduced liver and muscle glycogen stores. While carbohydrate utilization after such a diet is reduced, the limited glycogen stores can severely limit endurance exercise performance. High carbohydrate diets on the other hand expand carbohydrate stores which can limit performance. However, long-term adaptation to a low carbohydrate diet can greatly alter muscle and whole body energy metabolism to drastically limit the oxidation of limited carbohydrate stores with no adverse effect on performance. Glycogen loading techniques can result in supercompensation of muscle stores. Exercise induced depletion of muscle glycogen is the most important single factor in this phenomenon. Following the exercise a low carbohydrate diet for two to three days after which a high carbohydrate diet is eaten seemingly has the same effect on increasing muscle glycogen stores as simply eating a high carbohydrate diet. The form of the dietary carbohydrate during glycogen loading should be high in complex carbohydrates; however, the type of dietary starch that effects the greatest rate of resynthesis has not been investigated. Rapid resynthesis of glycogen following exercise is at least in part due to increased insulin sensitivity. The enhanced glucose transport caused by the increased sensitivity provides substrate for glycogen synthase. How rapidly this enhanced sensitivity returns to pre-exercise levels in humans is uncertain.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3993621

    Full Text Available Background: Little is known about the effects of dietary acculturation in minority groups in the Nordic countries, including immigrants from non-Western societies. Methods: A search was performed in Medlin33e/PubMed and SweMed+ for articles published in 1990–2011. Results: A total of 840 articles were identified, with a final 32 articles used to tabulate results which were included in the primary analysis. High rates of vitamin D deficiency (23 articles were found in immigrants of non-Western origin; deficiency rates were very high among both pregnant and non-pregnant women, and also among children, with young children of immigrant parents showing 50 times higher risk for rickets when compared to children of indigenous parents. The risk of iron deficiency (two articles was high among immigrant women, while the results were inconclusive regarding children. High rates of dental caries (seven articles were found among pre-school and younger school children of immigrant origin, while the risk of caries was not as evident among older children. In a secondary analysis, including 48 articles (results not tabulated, overweight and obesity (14 articles were seen in many immigrant groups, resulting in a high prevalence of diabetes (2 review articles from a total of 14 original articles and incidence of coronary heart disease (CHD; seven articles. For hypertension (three articles, dyslipidemia (four articles, and dietary patterns among immigrants (10 articles, the results were contradictory. Conclusions: Risk of vitamin D deficiency is alarmingly high in the Nordic countries among immigrants of non-Western origin, especially among women. Dental caries is high among immigrant children aged 0–7 years due to a higher intake of sugary products. Overweight and obesity, associated with a higher risk of diabetes and CHD, are prevalent in many immigrant groups and need further attention.

  4. Dietary fibre: consensus and controversy.

    Bijlani, R L

    1985-01-01

    Technological advances have reduced and refined man's plant food intake and consequently brought about an unprecedented decline in his consumption of dietary fibre (DF). The emergence of certain diseases selectively in regions which have been affected the most by this dietary change has led to an enhanced awareness of the functions of DF. DF is a heterogeneous group of substances which resist digestion by the endogenous enzymes of the human gut, although they are fermented to a substantial extent by the bacterial flora of the large intestine. Chemically, DF essentially consists of nonstarch polysaccharides and lignin, and its major constituents are cellulose, hemicelluose, lignin and pectin. The physiological effects of DF are attributable largely to its physicochemical properties. DF primarily affects gastrointestinal (GI) function; its effects are observable at all stages from ingestion through defaecation. It restricts caloric intake, shows gastric and small intestinal transit, and affects the activity of digestive enzymes and release of GI hormones. Its overall impact is to reduce apparent digestibility of nutrients marginally but consistently. In the large intestine, DF accelerates transit, supports bacterial growth and serves to hold water. As a result, the faecal weight and water content increase, and the transit time generally becomes shorter. Secondary to its GI effects, DF attenuates postprandial glycaemia and has long term effects on glucose tolerance and lipoprotein metabolism. These effects have important implications in the aetiopathogenesis of constipation and its sequelae including diverticulosis, cholesterol gallstones, colorectal cancer, obesity, diabetes mellitus and atherosclerosis. DF has traditionally been used therapeutically for constipation; now its use in diabetes is also well established. Our appreciation of the role of DF in human nutrition has undergone a major change in the last two decades. From a redundant constituent of plant foods

    Soya isoflavones: genistein and daidzein are increasingly consumed in Western countries. Their beneficial effects are discussed considering nutrition and health in Asia. The present study aimed to check whether chronic ingestions, ethnic origin and dietary context can influence soya phyto-oestrogen bioavailability. Two prospective trials were carried out to blindly assess the pharmacokinetics after acute and chronic intake of soya-based cheese (45.97 (sd1.57) mg isoflavones) taken once a day for 10 d. Twelve healthy young Asians immersed for 2 months in France were randomised in a cross-over design to compare the influence of a Western v. Asian dietary context. The second trial partly nested in the first one, compared Asians under the Western diet to twelve healthy young male Caucasians under the same diet. All volunteers were non-equol producers. After an acute intake of soya in Western diet, Asians exhibited higher maximum concentration measured in plasma (Cmax) and area under the plasma concentration-time curve (AUC) for genistein and daidzein than Caucasians (P = 0.005, 0.006, 0.032 and 0.008, respectively). In Caucasians under Western diet, AUC and Cmax values significantly increased after chronic intake. This was not the case for daidzein in Asians whatever the dietary context. For the first time, it is evidenced that on acute intake of soya cheese, Asians absorb soya phyto-oestrogens better than Caucasians, regardless of whether the background diet is Western or Asian. On chronic ingestions, AUC and Cmax values were increased for daidzein and genistein in Caucasians but not in Asians. There are ethnic differences in isoflavone pharmacokinetic and bioavailability. This may influence health outcomes. PMID:19622188

    Certain nutritional components influence the cellular metabolism and interfere in the pathological inflammatory process, so that they may act as a coadjuvant in the treatment of many chronic inflammatory diseases, including rheumatoid arthritis (RA). Particularly, a wide range of evidence has demonstrated the beneficial roles of dietary phenolic compounds in RA because of their ability to modulate pro-oxidant and pro-inflammatory pathways reducing the onset of arthritic disease progression. These natural phenolic compounds can modulate both the action and the production of inflammatory mediators either directly or indirectly by modulating the action of other molecules involved in RA pathology. Subsequently, the purpose of this article is to review the main in vitro and in vivo studies in RA, which have documented interesting insights into the antioxidant, anti-inflammatory, and immunomodulatory properties of dietary phenolic compounds focusing on their molecular action mechanisms involved in RA. The observations reported above are promising and suggest that the dietary phenolic compounds may influence the course of RA, ameliorating the RA symptoms and downregulating the inflammation at the molecular level; however, most of the studies conducted to date have been preclinical. Thus, future studies should therefore focus more on understanding the efficacy of these phenolic compounds in humans and bringing them to the forefront of the treatment of chronic human diseases.

    Current United States regulatory policies allow for the addition of pharmacologically active substances in dietary supplements if derived from a botanical source. The inclusion of certain nootropic drugs, such as vinpocetine, in dietary supplements has recently come under scrutiny due to the lack of defined dosage parameters and yet unproven short- and long-term benefits and risks to human health. This study quantified the concentration of vinpocetine in several commercially available dietary supplements and found that a highly variable range of 0.6-5.1 mg/serving was present across the tested products, with most products providing no specification of vinpocetine concentrations.

    2015-04-01

    Full Text Available Fetal life is characterized by a tremendous plasticity and ability to respond to various environmental and lifestyle factors, including maternal nutrition. Identification of the role of dietary factors that can modulate and reshape the cellular epigenome during development, including methyl group donors (e.g., folate, choline and bioactive compounds (e.g., polyphenols is of great importance; however, there is insufficient knowledge of a particular effect of each type of modulator and/or their combination on fetal life. To enhance the quality and safety of food products for proper fetal health and disease prevention in later life, a better understanding of the underlying mechanisms of dietary epigenetic modulators during the critical prenatal period is necessary. This review focuses on the influence of maternal dietary components on DNA methylation, histone modification, and microRNAs, and summarizes current knowledge of the effect and importance of dietary components on epigenetic mechanisms that control the proper expression of genetic information. Evidence reveals that some components in the maternal diet can directly or indirectly affect epigenetic mechanisms. Understanding the underlying mechanisms of how early-life nutritional environment affects the epigenome during development is of great importance for the successful prevention of adult chronic diseases through optimal maternal nutrition.

    Dietary lipids modulate immunity, yet the means by which specific fatty acids affect infectious disease susceptibility remains unclear. Deciphering lipid-induced immunity is critical to understanding the balance required for protecting against pathogens while avoiding chronic inflammatory diseases. To understand how specific lipids alter susceptibility to enteric infection, we fed mice isocaloric, high-fat diets composed of corn oil (rich in n-6 polyunsaturated fatty acids [n-6 PUFAs]), olive oil (rich in monounsaturated fatty acids), or milk fat (rich in saturated fatty acids) with or without fish oil (rich in n-3 PUFAs). After 5 weeks of dietary intervention, mice were challenged with Citrobacter rodentium, and pathological responses were assessed. Olive oil diets resulted in little colonic pathology associated with intestinal alkaline phosphatase, a mucosal defense factor that detoxifies lipopolysaccharide. In contrast, while both corn oil and milk fat diets resulted in inflammation-induced colonic damage, only milk fat induced compensatory protective responses, including short chain fatty acid production. Fish oil combined with milk fat, unlike unsaturated lipid diets, had a protective effect associated with intestinal alkaline phosphatase activity. Overall, these results reveal that dietary lipid type, independent of the total number of calories associated with the dietary lipid, influences the susceptibility to enteric damage and the benefits of fish oil during infection.

    Globally, more than 800 million people are undernourished while >2 billion people have one or more chronic micronutrient deficiencies (MNDs). More than 6% of global mortality and morbidity burdens are associated with undernourishment and MNDs. Here we show that, in 2011, 3.5 and 1.1 billion people were at risk of calcium (Ca) and zinc (Zn) deficiency respectively due to inadequate dietary supply. The global mean dietary supply of Ca and Zn in 2011 was 684 ± 211 and 16 ± 3 mg capita-1 d-1 (±SD) respectively. Between 1992 and 2011, global risk of deficiency of Ca and Zn decreased from 76 to 51%, and 22 to 16%, respectively. Approximately 90% of those at risk of Ca and Zn deficiency in 2011 were in Africa and Asia. To our knowledge, these are the first global estimates of dietary Ca deficiency risks based on food supply. We conclude that continuing to reduce Ca and Zn deficiency risks through dietary diversification and food and agricultural interventions including fortification, crop breeding and use of micronutrient fertilisers will remain a significant challenge.

    Full Text Available Diet plays a vital role in the management of cancer because they are the source of important physiologically functional components. Scientific observations support the idea that dietary supplement can prevent breast cancer recurrences. Strong correlations are established between the high intake of saturated fat and the incidence of different types of cancer. It is found that chronic alcohol consumption is associated with increased risk of cancers of oral cavity, pharynx, esophagus, and larynx. Again, some evidences are also found regarding phosphorous, glutamate level in the body, and incidence of cancer. Different physiologically functional components are found in the dietary materials. Fibers, the major dietary components, have long been recognized for the unique properties in the treatment of cancer, which are related to its antineoplastic functions. Antioxidant rich diet has been added to the list of cancer-preventing dietary components. Also, recently published research has shown that natural carotenoids in the diet leads to a normalization of body epithelial cells and protects against the risk of stomach and esophagus cancer, and improves the immune system′s response. Again, fruit juices, processed vegetable juices, orange peel, green tea, vitamins, flavonoids, and trace materials have cancer inhibitory properties. Clearly, there has been increasing recognition of chemoprotective functions. Now, it can be recognized for another kind of functionality for the improvement of the health of mankind.

    Full Text Available Abstract Background Given the rise in obesity and associated chronic diseases, it is critical to determine optimal weight management approaches that will also improve dietary composition and chronic disease risk factors. Few studies have examined all these weight, diet, and disease risk variables in subjects participating in recommended multi-disciplinary weight loss programs using different dietary strategies. Methods This study compared effects of three dietary approaches to weight loss on body composition, dietary composition and risk factors for metabolic syndrome (MetS. In a 12-week trial, sedentary but otherwise healthy overweight and obese adults (19 M & 138 F; 38.7 ± 6.7 y; BMI 31.8 ± 2.2 who were attending weekly group sessions for weight loss followed either portion control, low energy density, or low glycemic index diet plans. At baseline and 12 weeks, measures included anthropometrics, body composition, 3-day food diaries, blood pressure, total lipid profile, HOMA, C-reactive protein, and fasting blood glucose and insulin. Data were analyzed by repeated measures analysis of variance. Results All groups significantly reduced body weight and showed significant improvements in body composition (p  Conclusion Different dietary approaches based on portion control, low energy density, or low glycemic index produced similar, significant short-term improvements in body composition, diet compositin, and MetS components in overweight and obese adults undergoing weekly weight loss meetings. This may allow for flexibility in options for dietary counseling based on patient preference.

    Full Text Available The interest in food rich in dietary fiber increased in the recent decades, and the importance of this food constituent has led to the development of a large market for fibre-rich products and ingredients. A high dietary fiber intake has been related to several physiological and metabolic effects. By-products of plant food processing represent a major disposal problem for the industry concerned, but they are also promising sources of compounds which may be used because of their favourable technological or nutritional properties. Soluble dietary fiber is those components that are soluble in water and includes pectic substances and hydrocolloids. Good sources of soluble fibers include fruits, vegetables, legumes, soybeans, psyllium seeds and oat bran. Insoluble dietary fiber is those components that are insoluble in water and includes cellulose, hemicellulose and lignin. Whole grains are good sources of insoluble fiber.

    2016-07-01

    A five-food item food frequency questionnaire (FFQ) and a 3-day food diary (3DFD) were used to estimate daily dietary calcium (Ca) intake in 32 patients aged 1-17 years. Median and IQR of Ca intake from 3DFD was 840 mg and 438 mg while from FFQ it was 700 mg and 987 mg, respectively. The non-parametrical Bland-Altman limits of agreement plot between two methods showed that most of the values fell between the limits of agreement at +794 mg and -388 mg. The FFQ had a specificity of 93% in identifying children who consumed inadequate amount of dietary Ca and a sensitivity of 78% in identifying children whose dietary Ca intake exceeded UK's Reference Nutrient Intake. Thus the FFQ allows rapid estimation of children with low daily dietary Ca intake in the clinic setting; however it does not replace 3DFD. PMID:26662924

  3. Need of integrated dietary therapy for persons with diabetes mellitus and “unhealthy” body constitution presentations

    2016-01-01

    From a perspective of Chinese medicine (CM), persons with unregulated “unhealthy” body constitution (BC) wil further develop chronic diseases, such as diabetes melitus (DM). Conventional dietary therapy with nutrition component has its limitations in the regulation of “unhealthy” BC. However, empirical evidence supports that “unhealthy” BC can be regulated with food natures and fl avors from a perspective of CM. Presentations of “unhealthy” BC types, such as Yin-defi ciency, Yang-defi ciency and Yin-Yang-defi ciency were found in persons with DM. It would be necessary to regulate the “unhealthy” BC presentations with integration of conventional dietary therapy and Chinese food therapy. The ultimate goal is to either stabilize glycaemic control or prevent the development of other chronic diseases leading to reduction of disease burden, such as disease-related poor quality of life, stress of healthcare professionals and the rising of healthcare cost.

  4. Cancer preventive role of selected dietary factors

    Directory of Open Access Journals (Sweden)

    Ray Amitabha

    2005-01-01

    Full Text Available Dietary behavior seems to be an important modifiable determinant for the risk of cancer. The evidences from several epidemiological studies suggest that higher intakes of fruits and vegetables have been associated with lower risk of cancer. Dietary phenolic and polyphenolic substances, terpenoids, dietary fibers, fish oils, some micronutrients present in foods of both plant and animal origin, and a reduction of caloric intake appear to inhibit the process of cancer development. Many dietary factors possess antioxidant and anti-inflammatory properties and cause induction of phase II enzymes like glutathione-S-transferases. It has been suggested that cruciferous vegetables play an important role in cancer prevention, and their chemopreventive effects are due to high glucosinolate content which under enzymatic hydrolysis produces bioactive compound isothiocyanates. Further, isothiocyanates of a wide variety of cruciferous vegetables are powerful inhibitors of carcinogenesis in experimental animal models. Several flavonoids present in fruits, tea, soya beans, etc. may be useful as cancer preventive agents. Similarly, ellagic acid, perillyl alcohol and resveratrol found in various fruits may have chemoprotective effect. Moreover, different vanilloids such as curcumin and gingerol have been shown to possess antioxidative properties. Nevertheless, in spite of several studies, still the effects of various ingredients are not clearly distinguished. In human, little convincing evidence has been established for the proposed protective effects of dietary constituents. It is an important future research goal to provide necessary evidences to support the chemopreventive role of different dietary factors, and also to clarify misunderstandings in this perplexing area.

    The use of image-based dietary assessment methods shows promise for improving dietary self-report among children. The Technology Assisted Dietary Assessment (TADA) food record application is a self-administered food record specifically designed to address the burden and human error associated with conventional methods of dietary assessment. Users would take images of foods and beverages at all eating occasions using a mobile telephone or mobile device with an integrated camera [e.g. Apple iPhone, Apple iPod Touch (Apple Inc., Cupertino, CA, USA); Nexus One (Google, Mountain View, CA, USA)]. Once the images are taken, the images are transferred to a back-end server for automated analysis. The first step in this process is image analysis (i.e. segmentation, feature extraction and classification), which allows for automated food identification. Portion size estimation is also automated via segmentation and geometric shape template modeling. The results of the automated food identification and volume estimation can be indexed with the Food and Nutrient Database for Dietary Studies to provide a detailed diet analysis for use in epidemiological or intervention studies. Data collected during controlled feeding studies in a camp-like setting have allowed for formative evaluation and validation of the TADA food record application. This review summarises the system design and the evidence-based development of image-based methods for dietary assessment among children. PMID:23489518

    Many chronic diseases, including obesity and cancer, are related to diet. Such diseases may be prevented and/or successfully treated by accurately monitoring and assessing food and beverage intakes. Existing dietary assessment methods such as the 24-hour dietary recall and the food frequency questionnaire, are burdensome and not generally accurate. In this paper, we present a user interface for a mobile telephone food record that relies on taking images, using the built-in camera, as the primary method of recording. We describe the design and implementation of this user interface while stressing the solutions we devised to meet the requirements imposed by the image analysis process, yet keeping the user interface easy to use.

    International Nuclear Information System (INIS)

    The toxicity of dietary exposure to artificially aged TiO2 nanomaterial (T-Lite™) used in sunscreen cream was studied on D. magna. Pseudokirchneriella subcapitata cultures were contaminated with TiO2-residues, obtained by artificial aging. Significant association of TiO2-residues on algae was detected by X-ray fluorescence spectromicroscopy. A D. magna dietary chronic exposure of these contaminated algae with TiO2-residues was performed. X-ray chemical imaging revealed that Ti was localized only in the digestive tract of the daphnia. Chronic exposure of daphnia to by-product of aged TiO2 nanoparticles brought by food induced low mortality but decreased growth and reproduction which can be partly related to the modification of the digestive physiology of daphnia. This study demonstrated that the assessment of the ecotoxicological impact of nanomaterials in aquatic environment should take into account the aging of these materials which can further influence their bioavailability for aquatic organisms. - Highlights: ► Pseudokirchneriella subcapitata were contaminated with artificially aged TiO2 nanocomposites. ► Contaminated algae were used to fed Daphnia magna in a chronic dietary test. ► Dietary chronic exposure of TiO2 nano-residues decreased growth and reproduction. ► These effects could be partly related to the modification of the digestive physiology of daphnids. - By-products of aged TiO2 nanoparticles used in sunscreen cream taken in by food induced significant reproductive effects that could be linked to digestive physiology alteration.

    At the present, there is a pandemic of chronic non-communicable disease (NCD) affecting most countries of the world. The World Health Organisation (WHO) has identified the main contributing determinants to be cardiovascular disease (CVD), diabetes, malignant cancer and chronic disease of the respiratory system. Unhealthy nutrition, as well as other adverse lifestyle health behaviour are recognised to be part of the prime factors responsible. According to WHO guidelines, a healthy lifestyle should include substituting saturated fatty acids (SFAs) with polyunsaturated fatty acids (PUFAs) together with eliminating trans-fatty acids from the diet and limiting the intake of refined carbohydrates in conjunction with increasing the consumption of fruit, vegetables, nuts and wholegrain cereal products. Recent studies on the relations between CVD prevention and dietary fats have been however unclear. The present study thus aims to provide a review of current evidence and opinion on the type of dietary fat most appropriate for preventing arteriosclerosis. The adoption of dated recommendations on the need to increase dietary PUFA in both Northern Europe and America has led to n-6 PUFAs being predominant in diets as compared to n-3 PUFAs. This disproportion may have caused mortality to rise, due to CVD, as a result of arteriosclerosis in these countries. In contrast, a traditional Mediterranean diet yields a PUFA n-6/n-3 ratio of 2:1, which is much lower than for the aforementioned northern countries. Some authors however consider that assessing this ratio is irrelevant and that decreasing n-6 PUFA may be harmful. Such differences of opinion leads to confusion in adopting an effective approach for arteriosclerosis management regarding dietary n-6/n-3 ratios. Moreover, recent studies have added much controversy to the notion that the characteristics of SFAs are responsible for arteriosclerosis. These found that replacing dietary SFAs with carbohydrates did not reduce the risk

    OBJECTIVE: To quantify the dietary calcium and vitamin D intake in adult renal-transplant recipients attending at a large teaching hospital in Ireland for follow-up. SETTING: Outpatient renal-transplant follow-up clinic. SUBJECTS: Fifty-nine adult renal transplant recipients (58% male) with a mean age of 46 years, a median transplant duration of 6 years, and a mean estimated glomerular filtration rate (eGFR) of 50 mL\\/min per 1.73 m2. Fifty-three percent were at National Kidney Foundation stage 3 chronic kidney disease, and 14% had stage 4 chronic kidney disease. INTERVENTION: This cross-sectional, observational study used a tailored food frequency questionnaire specific for calcium and vitamin D intake in Irish adults, which was completed during a face-to-face interview with each subject. MAIN OUTCOME MEASURE: The main outcome measure was the average daily dietary and supplemented calcium and vitamin D intake. RESULTS: The median interquartile range (IQR) dietary calcium intake was 820 mg\\/day (range, 576-1,177 mg\\/day), and was similar in men and women (recommended intake > or = 1,000 mg\\/day in adult men and nonmenopausal adult women, > or = 1,500 mg\\/day in menopausal women). Five participants received calcium supplementation. Overall, 59% of men and 64% of women had total calcium intakes below the recommended amounts. The median IQR estimated dietary vitamin D intake was 5.2 microg\\/day (range, 2.4-6.4 microg\\/day) in women, and 4.6 microg\\/day (range, 2.2-6.6 microg\\/day) in men (recommended intake, > or = 10 microg\\/day). Six subjects received vitamin D supplementation. Total vitamin D intakes were suboptimal in 91% of men and 87% of women. Dietary calcium and vitamin D intakes significantly correlated with each other, but neither was significantly related to eGFR category, and was similarly low in both presumed menopausal women and in the initial year posttransplantation. CONCLUSION: These findings suggest that dietary and total calcium and

    Otitis media occurs along a continuum. For example, otitis media with effusion characterized by fluid pathology can lead to chronic otitis media plus chronic mastoiditis, characterized by the presence of intractable tissue pathology such as cholesteatoma, cholesterol granuloma or granulation tissue. The literature defines chronic otitis media as having a tympanic membrane perforation and otorrhea. Amongst many other sequelae, which can result from the continuum, an important common one is chronic silent otitis media. This overlooked entity which includes pathology beneath an intact tympanic membrane is commonly seen in our human temporal bone laboratory and in patients. The clinical pathological correlates of this important disease are discussed herein. PMID:12021496

    Although nutrition has been advocated as a major determinant of healthy ageing (HA), studies investigating the link between dietary quality and HA are scarce. We investigated the association between adherence to French food-based and nutrient-based guidelines at midlife, as assessed by three dietary scores, and HA. HA was assessed in 2007-2009, among 2329 participants of the SUpplémentation en Vitamines et Minéraux AntioXydants study aged 45-60 years at baseline (1994-1995) and initially free of diabetes, CVD and cancer. HA was defined as not developing any major chronic disease, good physical and cognitive functioning, no limitations in instrumental activities of daily living, no depressive symptoms, no health-related limitations in social life, good overall self-perceived health and no function-limiting pain. Data from repeated 24-h dietary records provided at baseline permitted the computation of the modified French Programme National Nutrition Santé-Guideline Score (mPNNS-GS), the Probability of Adequate Nutrient Intake Dietary Score (PANDiet) and the Diet Quality Index-International (DQI-I). Associations of these scores with HA were assessed by logistic regression. In 2007-2009, 42 % of men and 36 % of women met our criteria of HA. After adjustment for potential confounders, higher scores of the mPNNS-GS (ORquartile 4 v. quartile 1 1·44; 95 % CI 1·10, 1·87; P trend=0·006) and the PANDiet (1·28; 95 % CI 1·00, 1·64; P trend=0·03) were associated with higher odds of HA. We observed no association between DQI-I and HA. In conclusion, this study suggests a beneficial long-term role of high adherence to both food-based and nutrient-based French dietary guidelines for a HA process. PMID:27301412

    Early identification of chronic kidney disease (CKD) provides an opportunity to implement therapies to improve kidney function and slow progression. The goal of this article is to review established and developing clinical therapies directed at slowing progression. The importance of controlling blood pressure will be discussed along with the target blood pressure that should be achieved in CKD patients. Therapy directed at inhibiting the renin-angiotensin-aldosterone system remains the mainstay of treatment with single-agent inhibition of this system being as good as dual blockade with fewer adverse effects. Other therapies that may be used include correction of metabolic acidosis, dietary protein restriction, and new models for delivering care to patients with CKD. Emerging therapies targeting endothelin, uric acid, kidney fibrosis, and oxidant stress hold promise for the future. PMID:25019022

    Diet therapy is an important factor in overall care of most GI patients. Historically, diets have been used unscientifically in many of these patients without positive results. Nutritional care and diet therapy are critical for two reasons. First, malnutrition is an expected sequelae to most, if not all, GI diseases or disorders. Failure to eat, digest, or assimilate nutrients can provoke malnutrition in just a few weeks, although careful assessment of anthropometric, clinical, biochemical, and nutritional history by a trained professional can protect against this. Diet therapy through the elimination of offending foods such as wheat gluten or lactose, or inclusion of specialized products such as medium chain triglycerides or elemental formulas, can sustain nutritional status. Dietary components such as insoluble fiber appear to have physiologic effects, while soluble fibers may have metabolic effects important to diabetes and cardiovascular disease. There is a high potential for malnutrition in Crohn's disease during active and remittent phases. Elemental enteral formulas or TPN are used during the active phase to ensure optimal nutritional status and bowel rest. Hyperalimentation using the GI tract during remittent stage maintains this. Avoiding offending foods by Crohn's patients is an acceptable practice as long as entire categories of foods are not deleted. Avoiding all foods containing gluten from wheat, rye, barley, and oats, however, is a crucial prerequisite to recovery from celiac disease. Gluten is commonly used as a stabilizer, emulsifier, and extender in the food industry and is not always shown on food labels. Careful consultation with a registered dietitian can identify hidden sources of gluten in the diet.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2647390

    Despite interventions designed to change behavior, many adolescents continue to consume unhealthy foods. Dietary patterns are important for disease prevention, making it necessary to understand the reasons for these poor choices. This cross-sectional study explored the relationship between perception of dietary practices and dietary behaviors among adolescents. Participants (n=15,283; mean age=15 years; 50.7% female) completed the 2004-2005 Texas School Physical Activity and Nutrition survey. Perception of dietary practices included fat content of foods usually eaten and healthiness of usual eating habits. Dietary behavior was measured by self-report of foods eaten the day before survey administration. Composite scores of unhealthy and healthy eating were created. Regression analyses examined whether perception of dietary practices was consistent with actual dietary behavior, controlling for sex, grade, and race/ethnicity, and accounting for the complex sampling design. Higher perceived fat content was associated with increased consumption of unhealthy foods, while higher perceived healthiness of eating was associated with increased consumption of healthy foods. For perceived fat content, the difference in the Healthy Eating Index between extreme categories was 26% (P<0.001), while the difference in the Unhealthy Eating Index between extreme categories was 81% (P<0.001). For perceived healthiness, the difference in the Healthy Eating Index between extreme categories was 23% (P<0.001), while the difference for the Unhealthy Eating Index was 44% (P<0.001). Self-perceptions of dietary practices were significantly associated with dietary behaviors, indicating awareness about the relative nutrient content of foods consumed. Interventions that move beyond dietary knowledge and create changes in the social and physical environment are needed. PMID:22027057

  7. Dietary Nitrate, Nitric Oxide, and Cardiovascular Health.

    Science.gov (United States)

    Bondonno, Catherine P; Croft, Kevin D; Hodgson, Jonathan M

    2016-09-01

    Emerging evidence strongly suggests that dietary nitrate, derived in the diet primarily from vegetables, could contribute to cardiovascular health via effects on nitric oxide (NO) status. NO plays an essential role in cardiovascular health. It is produced via the classical L-arginine-NO-synthase pathway and the recently discovered enterosalivary nitrate-nitrite-NO pathway. The discovery of this alternate pathway has highlighted dietary nitrate as a candidate for the cardioprotective effect of a diet rich in fruit and vegetables. Clinical trials with dietary nitrate have observed improvements in blood pressure, endothelial function, ischemia-reperfusion injury, arterial stiffness, platelet function, and exercise performance with a concomitant augmentation of markers of NO status. While these results are indicative of cardiovascular benefits with dietary nitrate intake, there is still a lingering concern about nitrate in relation to methemoglobinemia, cancer, and cardiovascular disease. It is the purpose of this review to present an overview of NO and its critical role in cardiovascular health; to detail the observed vascular benefits of dietary nitrate intake through effects on NO status as well as to discuss the controversy surrounding the possible toxic effects of nitrate.

  8. Estimating the Distribution of Dietary Consumption Patterns

    2014-02-01

    In the United States the preferred method of obtaining dietary intake data is the 24-hour dietary recall, yet the measure of most interest is usual or long-term average daily intake, which is impossible to measure. Thus, usual dietary intake is assessed with considerable measurement error. We were interested in estimating the population distribution of the Healthy Eating Index-2005 (HEI-2005), a multi-component dietary quality index involving ratios of interrelated dietary components to energy, among children aged 2-8 in the United States, using a national survey and incorporating survey weights. We developed a highly nonlinear, multivariate zero-inflated data model with measurement error to address this question. Standard nonlinear mixed model software such as SAS NLMIXED cannot handle this problem. We found that taking a Bayesian approach, and using MCMC, resolved the computational issues and doing so enabled us to provide a realistic distribution estimate for the HEI-2005 total score. While our computation and thinking in solving this problem was Bayesian, we relied on the well-known close relationship between Bayesian posterior means and maximum likelihood, the latter not computationally feasible, and thus were able to develop standard errors using balanced repeated replication, a survey-sampling approach.

    The effects of dietary cadmium (Cd) supplementation on growth, antioxidant capacity and accumulation of Cd in tissues (body wall, digestive tracts, and respiratory tree) of sea cucumber, Apostichopus japonicus, exposed to sub-chronic concentrations (0, 10, 50, 100, and 500mg Cd/kg dry weight) of Cd were investigated. In addition, the potential protective effects of vitamin C (L-ascorbic acid, AsA) against the effects of Cd on sea cucumbers were investigated. Sea cucumbers were exposed to dietary Cd for 30 days, after which another group of healthy sea cucumbers was supplied diet supplemented with mixed Cd and AsA for another 30 days. Cd exposure for 30 days resulted in increased Cd accumulation in tissues of sea cucumbers with exposure time and concentration. The order of Cd accumulation in organs was digestive tracts>respiratory tree>body wall. On day 30, the body weight gain (BWG) and specific growth rate (SGR) decreased significantly (P<0.05) in the 500mg Cd/kg treatment. Superoxide dismutase (SOD) activity, glutathione peroxidase (GSH-Px) activity and catalase (CAT) activity in the coelomic fluid of sea cucumbers decreased with increasing dietary Cd concentration, but malondialdehyde (MDA) content in the coelomic fluid increased. Providing diet supplemented with Cd and AsA indicated that although sea cucumbers exhibited signs of Cd toxicity, no death occurred in response to 50mg Cd/kg for 30 days. Based on these findings, five treatments were provided: 50mg Cd/kg+0mg AsA/kg, 50mg Cd/kg+ 3000mg AsA/kg, 50mg Cd/kg+ 5000mg AsA/kg, 50mg Cd/kg+10,000mg AsA/kg, and 50mg Cd/kg+15,000mg AsA/kg. The BWG and SGR of sea cucumbers fed the AsA supplemented diet mixed with Cd increased. Additionally, MDA levels in coelomic fluid were negatively correlated with dietary AsA levels, while antioxidant capacities (SOD, GSH-Px and CAT) were positively correlated with dietary AsA levels. Moreover, Cd accumulation in tissues decreased in response to dietary AsA supplementation of

    2006-01-01

    Full Text Available Introduction. The prevalence of chronic diseases in adolescence is constantly increasing, especially in the last two decades. Adolescence is a period of important changes: body growth and development, sexual development, development of cognitive abilities, change in family relations and between peers, formation of personal identity and personal system of values, making decisions on future occupation etc. Chronic diseases in adolescence. Chronic disorders affect all development issues and represent an additional burden for adolescents. The interaction between chronic disorders and various development issues is complex and two-way: the disease may affect development, and development may affect the disease. Developmental, psychosocial and family factors are of great importance in the treatment of adolescents with chronic disorders. Chronic disorders affect all aspects of adolescent life, including relations with peers, school, nutrition, learning, traveling, entertainment, choice of occupation, plans for the future. Physicians should keep in mind that chronic diseases and their treatment represent only one aspect of person's life. Adolescents with chronic diseases have other needs as well, personal priorities, social roles and they expect these needs to be recognized and respected. Adolescent health care should be adjusted to the life style of adolescents.

    We define chronic migraine as that clinical situation in which migraine attacks appear 15 or more days per month. Until recently, and in spite of its negative impact, patients with chronic migraine were excluded of the clinical trials. This manuscript revises the current treatment of chronic migraine. The first step should include the avoidance of potential precipitating/aggravating factors for chronic migraine, mainly analgesic overuse and the treatment of comorbid disorders, such as anxiety and depression. The symptomatic treatment should be based on the use of nonsteroidal anti-inflammatory agents and triptans (in this case ergotamine-containing medications. Preventive treatment includes a 'transitional' treatment with nonsteroidal anti-inflammatory agents or steroids, while preventive treatment exerts its actions. Even though those medications efficacious in episodic migraine prevention are used, the only drugs with demonstrated efficacy in the preventive treatment of chronic migraine are topiramate and pericranial infiltrations of Onabotulinumtoxin A.

    The dietary advice is a part of the global care for type 2 diabetes. First, overweight implies a caloric restriction. When poor glucose control is associated with weight gain, important errors are obvious (excess fat and sugar), providing more pills or insulin without correcting them is poorly effective, but promotes further weight gain. Normal body weight, or poor glucose control despite loss of weight, needs to reappraise the diagnosis: diabetes type, intercurrent disease. The cofactors of the "metabolic syndrom" are usually present, so saturated fat has to be reduced, while maintaining fish, fruits, vegetables and whole grain cereals. Blood pressure and dyslipidemia may need further counselling about dietary sodium, carbohydrates, cholesterol. When insulin, sulfonylurea or glinids are indicated, the dietary intake of carbohydrates has to be regular to avoid hypoglycemia. PMID:20465121

    Dietary intake provides valuable insights for mounting intervention programs for prevention of disease. With growing concern for adolescent obesity, the need to accurately measure diet becomes imperative. Assessment among adolescents is problematic as this group has irregular eating patterns and have less enthusiasm for recording food intake. Preliminary studies among adolescents suggest that innovative use of technology may improve the accuracy of diet information from young people. In this paper we describe further development of a novel dietary assessment system using mobile devices. This system will generate an accurate account of daily food and nutrient intake among adolescents. The mobile computing device provides a unique vehicle for collecting dietary information that reduces burden on records that are obtained using more classical approaches. Images before and after foods are eaten can be used to estimate the amount of food consumed.

  17. Underutilized sources of dietary fiber: a review.

    McKee, L H; Latner, T A

    2000-01-01

    Interest in the fiber content of foods has decreased in recent years as concerns about fat intake have increased. Fiber, however, remains an important component of the diet. Soluble dietary fiber, including pectic substances and hydrocolloids, is found naturally in foods such as fruits, vegetables, legumes and oat bran. Insoluble fiber, including cellulose and hemicellulose, is found in foods such as whole grains. Fiber supplementation has been used to enhance the fiber content of a variety of foods ranging from cereal-based products to meats, imitation cheeses and sauces. Products used to enhance fiber content of foods have traditionally come from cereals such as wheat, corn and oats. There are a variety of other products, however, such as fruits, vegetables, legumes and less commonly used cereals such as barley, which are potential sources of dietary fiber supplements. This article reviews research on some of these underutilized sources of dietary fiber. PMID:11086873

    2015-04-01

    Full Text Available microRNAs (miRNAs, a class of small RNAs, are important regulators of various developmental processes in both plants and animals. Several years ago, a report showed the detection of diet-derived plant miRNAs in mammalian tissues and their regulation of mammalian genes, challenging the traditional functions of plant miRNAs. Subsequently, multiple efforts have attempted to replicate these findings, with the results arguing against the uptake of plant dietary miRNAs in healthy consumers. Moreover, several reports suggest the potential for “false positive” detection of plant miRNAs in human tissues. Meanwhile, some research continues to suggest both the presence and function of dietary miRNAs in mammalian tissues. Here we review the recent literature and discuss the strengths and weaknesses of emerging work that suggests the feasibility of dietary delivery of miRNAs. We also discuss future experimental approaches to address this controversial topic.

    Dietary patterns derived by statistical procedures is a way to identify overall dietary habits in specific populations. The aim of this study was to identify and characterise dietary patterns in Swedish adults using data from the national dietary survey Riksmaten adults 2010-11 (952 women, 788 men). Principal component analyses were used and two patterns were identified in both sexes: a healthy pattern loading positively on vegetables, fruits, fish and seafood, and vegetable oils, and negatively on refined bread and fast food, and a Swedish traditional pattern loading positively on potatoes, meat and processed meat, full-fat milk products, sweet bakery products, sweet condiments and margarine. In addition, a light-meal pattern was identified in women with positive loadings on fibre-rich bread, cheese, rice, pasta and food grain dishes, substitute products for meat and dairy products, candies and tea. The healthy pattern was positively correlated to dietary fibre (r 0·51-0·58) and n-3 (r 0·25-0·31) (all Psugar (r 0·20-0·25) and the Swedish traditional also to SFA (r 0·13-0·21) (all P<0·0001); both patterns were in general negatively correlated to micronutrients. Dietary pattern scores were associated with, for example, age, physical activity, education and income. In conclusion, we identified three major dietary patterns among Swedish adults. The patterns can be further used for examining the association between whole diet and health outcomes. PMID:26490112

    2009-12-01

    Full Text Available Abstract Background The current food pyramid guidelines have been criticized because of their complexity and the knowledge required for users to understand the recommendations. Simplification of a dietary message to focus on a single key aspect of dietary quality, e.g., fiber intake, may make the message much easier to comprehend and adhere, such that respondents can achieve greater weight loss, better dietary quality and overall metabolic health. Methods and design This is a randomized controlled clinical trial with two equal sized arms. In total, 240 obese adults who meet diagnostic criteria for the metabolic syndrome will be randomized to one of the two conditions: 1 a high fiber diet and 2 the American Heart Association (AHA diet. In the high fiber diet condition, patients will be given instruction only on achieving daily dietary fiber intake of 30 g or more. In the AHA diet condition, patients will be instructed to make the several dietary changes recommended by the AHA 2006 guidelines. The trial examines participant weight loss and dietary quality as well as changes in components of the metabolic syndrome, inflammatory biomarkers, low-density lipoprotein cholesterol levels, insulin levels, and glycosolated hemoglobin. Potential mediators, i.e., diet adherence and perceived ease of the diet, and the intervention effect on weight change will also be examined. Discussions The purpose of this paper is to outline the study design and methods for testing the simple message of increasing dietary fiber. If the simple dietary approach is found efficacious for weight loss; and, improves dietary quality, metabolic health, and adherence, it might then be used to develop a simple public health message.

  13. [Chronic intestinal pseudo-obstruction].

    Science.gov (United States)

    Ohkubo, Hidenori; Inoh, Yumi; Fuyuki, Akiko; Nakajima, Atsushi

    2015-05-01

    Chronic intestinal pseudo-obstruction(CIPO) is a rare severe digestive disease in which clinical symptoms of intestinal obstruction appear without any mechanical cause. Pathophysiologically, CIPO shows ineffective intestinal propulsion due to an impairment of intestinal smooth muscle, enteric nervous system, and interstitial cells of Cajal(ICC). Sustained increased intra-bowel pressure often causes small intestinal malabsorption and bacterial translocation, and leads to malnutrition and blood stream infection (sepsis). Key points of the medical approach for CIPO are to improve nutritional status and reduce abdominal symptoms. Dietary cure and defecation control are the main options in mild cases, whereas home-parenteral-nutrition(HPN) and decompression therapy are often needed in severe cases. Stimulant laxatives, prokinetics and herbal medicine are usually used but often in fail. Percutaneous endoscopic gastrojejunostomy(PEG-J) tube may be burdenless compared to conventional ileus tube. Most important points in the management of this disease are to make a correct diagnosis as early as possible and avoid unnecessary surgery. However, no clear diagnostic criteria have been established so far. Manometry, scintigraphy, and full-thickness biopsy are the major examination for the CIPO diagnosis in the Western countries; however these specialized examinations are not popular in Japan. Therefore the Research Group(chief investigator, Atsushi Nakajima) proposed Japanese diagnostic criteria in 2009 to facilitate the diagnosis of this rare disease by the general physician. In 2013, we have reported that cine-MRI is a non-invasive diagnostic method for CIPO. Although further data are eagerly awaited, it can become a promising diagnostic tool in CIPO patients. Furthermore the Japanese criteria have been revised, and in 2014, the comprehensive criteria from a child to an adult have been devised. In 2015, CIPO is newly certified as Specified Rare and Intractable Disease which is

    Full Text Available Context Dietary proteins and amino acids can modulate pancreatic function. Objective Our aim was to estimate the levels of plasma amino acids in chronic pancreatitis patients and study their relationship with disease characteristics as well as exocrine and endocrine insufficiency. Patients One hundred and seventy-five consecutive adult patients with chronic pancreatitis: 84 patients with alcoholic chronic pancreatitis and 91 patients with tropical chronic pancreatitis. One hundred and thirteen healthy controls were also studied. Design Prospective study. Main outcome measures Disease characteristics and imaging features were recorded. Plasma-free amino acid levels were estimated using reverse-phase high-performance liquid chromatography. Polyclonal antibody ELISA was used to assess pancreatic fecal elastase-1. Results The majority of the plasma free amino acid levels decreased in chronic pancreatitis patients whereas glutamate, glycine, proline and lysine were elevated as compared to the controls. Multivariate logistic regression analysis revealed that the decrease in branched chain amino acid concentration was significantly associated with the presence of diabetes and low fecal elastase-1. In addition, a significant positive correlation was observed between branched chain amino acids and pancreatic elastase-1 (rs=0.724, P

  4. Interaction of Dietary Fatty Acids with Tumour Necrosis Factor Family Cytokines during Colon Inflammation and Cancer

    Directory of Open Access Journals (Sweden)

    Jiřina Hofmanová

    2014-01-01

    Full Text Available Intestinal homeostasis is precisely regulated by a number of endogenous regulatory molecules but significantly influenced by dietary compounds. Malfunction of this system may result in chronic inflammation and cancer. Dietary essential n-3 polyunsaturated fatty acids (PUFAs and short-chain fatty acid butyrate produced from fibre display anti-inflammatory and anticancer activities. Both compounds were shown to modulate the production and activities of TNF family cytokines. Cytokines from the TNF family (TNF-α, TRAIL, and FasL have potent inflammatory activities and can also regulate apoptosis, which plays an important role in cancer development. The results of our own research showed enhancement of apoptosis in colon cancer cells by a combination of either docosahexaenoic acid (DHA or butyrate with TNF family cytokines, especially by promotion of the mitochondrial apoptotic pathway and modulation of NFκB activity. This review is focused mainly on the interaction of dietary PUFAs and butyrate with these cytokines during colon inflammation and cancer development. We summarised recent knowledge about the cellular and molecular mechanisms involved in such effects and outcomes for intestinal cell behaviour and pathologies. Finally, the possible application for the prevention and therapy of colon inflammation and cancer is also outlined.

    Variation in ability to detect, recognize, and perceive sweetness may influence food consumption, and eventually chronic nutrition-related conditions such as overweight and obesity. The aim of this study was to investigate the associations between sweet taste function, anthropometry, and dietary intake in adults. Participants' (n = 60; mean age in years = 26, SD = ±7.8) sweet taste function for a range of sweeteners (glucose, fructose, sucrose, sucralose, erythritol, and Rebaudioside A) was assessed by measuring detection and recognition thresholds and sweetness intensity. Height, weight, and waist circumference were also measured, and participants also completed a Food Frequency Questionnaire. There was large inter-individual variation in detection, recognition and sweetness intensity measures. Pearson's correlation coefficient revealed no robust correlations between measures of sweet taste function, anthropometry, and dietary intake, with the exception of suprathreshold intensity, which was moderately correlated with total energy intake (r = 0.23-0.40). One-way analysis of variance revealed no significant differences between the most and least sensitive participants in terms of BMI, waist circumference, and dietary intake for all measures of sweet taste function and sweeteners (all p > 0.01). When stratified into BMI categories, there were no significant differences in any measure of sweet taste function between the normal weight and overweight/obese participants (all p > 0.01). Results show that that sweet taste function is not associated with anthropometry and sweetness intensity measures are the most appropriate measure when assessing links between sweet taste and food consumption.

    2015-06-01

    Until now, the literatures on the effects of food parenting practices and parents' own dietary behavior on children's dietary behavior have largely been independent from one another. Integrating findings across these areas could provide insight on simultaneous and interacting influences on children's food intake. In this narrative review, we provide a conceptual model that bridges the gap between both literatures and consists of three main hypotheses. First, parental dietary behavior and food parenting practices are important interactive sources of influence on children's dietary behavior and Body Mass Index (BMI). Second, parental influences are importantly mediated by changes in the child's home food environment. Third, parenting context (i.e., parenting styles and differential parental treatment) moderates effects of food parenting practices, whereas child characteristics (i.e., temperament and appetitive traits) mainly moderate effects of the home food environment. Future studies testing (parts of) this conceptual model are needed to inform effective parent-child overweight preventive interventions. PMID:25681294

    Allegri, C; Turconi, G; Cena, H

    2011-12-01

    This article reviews Western dietary attitudes and lifestyle choices by identifying the environmental, social and personal factors that determine said attitudes and choices. Environmental factors exert a major influence on, and complicate, dietary behavior, primarily by facilitating the consumption of meals away from home and by minimizing time dedicated to meal preparation and consumption. Social factors, from mass media to advertising and cultural traditions, also influence food intake, to an extent that is still underestimated. Ignorance of the real influence of environment and society on food choices could well blind consumers to the real significance of such choices. Accordingly, this review discusses differing aspects of emerging dietary trends and/or philosophies, and underlines their potentially harmful influence on health. Western countries are increasingly witnessing a dichotomy between the findings of nutritional science and the choices that dietary trends propose and impose. Coinciding with the obesity epidemic and the spread of other food-related diseases, this dichotomy calls for the development of effective preventive strategies. PMID:22526128

  18. Short Tools to Assess Young Children's Dietary Intake: A Systematic Review Focusing on Application to Dietary Index Research

    Directory of Open Access Journals (Sweden)

    Lucinda K. Bell

    2013-01-01

    Full Text Available Dietary indices evaluate diet quality, usually based on current dietary guidelines. Indices can therefore contribute to our understanding of early-life obesity-risk dietary behaviours. Yet indices are commonly applied to dietary data collected by onerous methods (e.g., recalls or records. Short dietary assessment instruments are an attractive alternative to collect data from which to derive an index score. A systematic review of studies published before April 2013 was conducted to identify short (≤50 items tools that measure whole-of-diet intake of young children (birth-five years and are applicable to dietary indices, in particular screening obesogenic dietary behaviours. The search identified 3686 papers of which 16, reporting on 15 tools (n=7, infants and toddlers birth-24 months; n=8, preschoolers 2–5 years, met the inclusion criteria. Most tools were food frequency questionnaires (n=14, with one innovative dietary questionnaire identified. Seven were tested for validity or reliability, and one was tested for both. Six tools (n=2, infants and toddlers; n=4, preschoolers are applicable for use with current dietary indices, five of which screen obesogenic dietary behaviours. Given the limited number of brief, valid and reliable dietary assessment tools for young children to which an index can be applied, future short tool development is warranted, particularly for screening obesogenic dietary behaviours.

    2014-10-01

    Full Text Available Introduction : Unhealthy dietary habits are a major risk factor for chronic diseases, particularly if adopted during early adulthood. In a study conducted on a large sample of university students from both public and private universities in Lebanon, we observed differences in obesity prevalence between males and females. Given this difference, the objective of this analysis was to define the different dietary patterns among university students, focusing on correlation with gender and body mass index (BMI. Methods : A cross-sectional study was carried out on 3384 students, using a proportionate cluster sample of Lebanese students from both public and private universities. Results : Three dietary patterns were identified among university youth namely, vegetarian/low calorie diet (mainly plant food while avoiding ‘western’ food, composite dishes, and bread; mixed diet (high consumption of plant food, followed by composite dishes, bread, and a low consumption of western type food, and finally the westernized diet (high consumption of white bread and western food, and a strong avoidance of plant food and composite dishes. We observed significant differences between males and females in terms of their reported food intake and dietary patterns. Females were particularly more prone to adopt the vegetarian/low calorie diet than males (ORa=1.69; p<0.001, while males were more likely to adopt a westernized diet (ORa=1.51; p<0.001, seemingly in private universities (p=0.053. Students with high income and obese students (BMI ≥ 30 kg/m2 were more likely to consume vegetarian/low calorie diets (P<0.05. Conclusion: Male university students, despite having a higher BMI, reported a higher consumption of food according to a westernized dietary pattern as compared to female university students in Lebanon, while the latter reported a higher adoption of a vegetarian diet. Health promotion programs are needed among university youth in Lebanon to address their

  20. Lipotoxicity: Effects of Dietary Saturated and Transfatty Acids

    Directory of Open Access Journals (Sweden)

    Débora Estadella

    2013-01-01

    Full Text Available The ingestion of excessive amounts of saturated fatty acids (SFAs and transfatty acids (TFAs is considered to be a risk factor for cardiovascular diseases, insulin resistance, dyslipidemia, and obesity. The focus of this paper was to elucidate the influence of dietary SFA and TFA intake on the promotion of lipotoxicity to the liver and cardiovascular, endothelial, and gut microbiota systems, as well as on insulin resistance and endoplasmic reticulum stress. The saturated and transfatty acids favor a proinflammatory state leading to insulin resistance. These fatty acids can be involved in several inflammatory pathways, contributing to disease progression in chronic inflammation, autoimmunity, allergy, cancer, atherosclerosis, hypertension, and heart hypertrophy as well as other metabolic and degenerative diseases. As a consequence, lipotoxicity may occur in several target organs by direct effects, represented by inflammation pathways, and through indirect effects, including an important alteration in the gut microbiota associated with endotoxemia. Interactions between these pathways may perpetuate a feedback process that exacerbates an inflammatory state. The importance of lifestyle modification, including an improved diet, is recommended as a strategy for treatment of these diseases.

  1. Epigenetic inheritance and evolution: A paternal perspective on dietary influences.

    Science.gov (United States)

    Soubry, Adelheid

    2015-07-01

    The earliest indications for paternally induced transgenerational effects from the environment to future generations were based on a small number of long-term epidemiological studies and some empirical observations. Only recently have experimental animal models and a few analyses on human data explored the transgenerational nature of phenotypic changes observed in offspring. Changes include multiple metabolic disorders, cancer and other chronic diseases. These phenotypes cannot always be explained by Mendelian inheritance, DNA mutations or genetic damage. Hence, a new compelling theory on epigenetic inheritance is gaining interest, providing new concepts that extend Darwin's evolutionary theory. Epigenetic alterations or "epimutations" are being considered to explain transgenerational inheritance of parentally acquired traits. The responsible mechanisms for these epimutations include DNA methylation, histone modification, and RNA-mediated effects. This review explores the literature on a number of time-dependent environmentally induced epigenetic alterations, specifically those from dietary exposures. We suggest a role for the male germ line as one of nature's tools to capture messages from our continuously changing environment and to transfer this information to subsequent generations. Further, we open the discussion that the paternally inherited epigenetic information may contribute to evolutionary adaptation. PMID:25769497

  2. Effect of Keishibukuryogan on Genetic and Dietary Obesity Models

    2015-01-01

    Full Text Available Obesity has been recognized as one of the most important risk factors for a variety of chronic diseases, such as diabetes, hypertension/cardiovascular diseases, steatosis/hepatitis, and cancer. Keishibukuryogan (KBG, Gui Zhi Fu Ling Wan in Chinese is a traditional Chinese/Japanese (Kampo medicine that has been known to improve blood circulation and is also known for its anti-inflammatory or scavenging effect. In this study, we evaluated the effect of KBG in two distinct rodent models of obesity driven by either a genetic (SHR/NDmcr-cp rat model or dietary (high-fat diet-induced mouse obesity model mechanism. Although there was no significant effect on the body composition in either the SHR rat or the DIO mouse models, KBG treatment significantly decreased the serum level of leptin and liver TG level in the DIO mouse, but not in the SHR rat model. Furthermore, a lower fat deposition in liver and a smaller size of adipocytes in white adipose tissue were observed in the DIO mice treated with KBG. Importantly, we further found downregulation of genes involved in lipid metabolism in the KBG-treated liver, along with decreased liver TG and cholesterol level. Our present data experimentally support in fact that KBG can be an attractive Kampo medicine to improve obese status through a regulation of systemic leptin level and/or lipid metabolism.

    Full Text Available INTRODUCTION Multiple sclerosis is an immune-mediated disease that produces chronic inflammation and neural degeneration. The disease progresses with acute attacks that result in myelin inflammation. This in turn increases oxidative stress and favors the appearance of reactive oxygen species. Reactive oxygen species damage neural cells causing apoptosis. The etiology of multiple sclerosis remains unknown and current therapy is aggressive and expensive. Recently, complementary and alternative medicine therapies have been proposed to control pathogenesis and symptoms of this disease. It is believed that these therapies help slow the progression of multiple sclerosis and improve survival. METHODS We conducted a MEDLINE/PubMed search using the following MeSH terms: diet, multiple sclerosis, antioxidants. We selected the main articles containing multiple sclerosis and diet. RESULTS We analyzed three case control studies that evaluated different dietary approaches in multiple sclerosis. For this review, we also included five experimental studies that studied the efficacy of lipoic acid in humans and rodents in diseases like multiple sclerosis, experimental autoimmune encephalomyelitis, and breast cancer.

    Full Text Available Flavonoids are ubiquitous in nature. They are also in food, providing an essential link between diet and prevention of chronic diseases including cancer. Anticancer effects of these polyphenols depend on several factors: Their chemical structure and concentration, and also on the type of cancer. Malignant cells from different tissues reveal somewhat different sensitivity toward flavonoids and, therefore, the preferences of the most common dietary flavonoids to various human cancer types are analyzed in this review. While luteolin and kaempferol can be considered as promising candidate agents for treatment of gastric and ovarian cancers, respectively, apigenin, chrysin, and luteolin have good perspectives as potent antitumor agents for cervical cancer; cells from main sites of flavonoid metabolism (colon and liver reveal rather large fluctuations in anticancer activity probably due to exposure to various metabolites with different activities. Anticancer effect of flavonoids toward blood cancer cells depend on their myeloid, lymphoid, or erythroid origin; cytotoxic effects of flavonoids on breast and prostate cancer cells are highly related to the expression of hormone receptors. Different flavonoids are often preferentially present in certain food items, and knowledge about the malignant tissue-specific anticancer effects of flavonoids could be purposely applied both in chemoprevention as well as in cancer treatment.

  5. Effect of Dietary Bioactive Compounds on Mitochondrial and Metabolic Flexibility

    2016-03-01

    Full Text Available Metabolic flexibility is the capacity of an organism to adequately respond to changes in the environment, such as nutritional input, energetic demand, etc. An important player in the capacity of adaptation through different stages of metabolic demands is the mitochondrion. In this context, mitochondrial dysfunction has been attributed to be the onset and center of many chronic diseases, which are denoted by an inability to adapt fuel preferences and induce mitochondrial morphological changes to respond to metabolic demands, such as mitochondrial number, structure and function. Several nutritional interventions have shown the capacity to induce changes in mitochondrial biogenesis/degradation, oxidative phosphorylation efficiency, mitochondrial membrane composition, electron transfer chain capacity, etc., in metabolic inflexibility states that may open new target options and mechanisms of action of bioactive compounds for the treatment of metabolic diseases. This review is focused in three well-recognized food bioactive compounds that modulate insulin sensitivity, polyphenols, ω-3 fatty acids and dietary fiber, by several mechanism of action, like caloric restriction properties and inflammatory environment modulation, both closely related to mitochondrial function and dynamics.

    Science.gov (United States)

    Stevens, Whitney W; Lee, Robert J; Schleimer, Robert P; Cohen, Noam A

    2015-12-01

    There are a variety of medical conditions associated with chronic sinonasal inflammation, including chronic rhinosinusitis (CRS) and cystic fibrosis. In particular, CRS can be divided into 2 major subgroups based on whether nasal polyps are present or absent. Unfortunately, clinical treatment strategies for patients with chronic sinonasal inflammation are limited, in part because the underlying mechanisms contributing to disease pathology are heterogeneous and not entirely known. It is hypothesized that alterations in mucociliary clearance, abnormalities in the sinonasal epithelial cell barrier, and tissue remodeling all contribute to the chronic inflammatory and tissue-deforming processes characteristic of CRS. Additionally, the host innate and adaptive immune responses are also significantly activated and might be involved in pathogenesis. Recent advancements in the understanding of CRS pathogenesis are highlighted in this review, with special focus placed on the roles of epithelial cells and the host immune response in patients with cystic fibrosis, CRS without nasal polyps, or CRS with nasal polyps.

    Lopes Roberto I

    2003-01-01

    Full Text Available Chronic penile strangulation is exceedingly rare with only 5 cases previously reported. We report an additional case of progressive penile lymphedema due to chronic intermittent strangulation caused by a rubber band applied to the penile base for 6 years. A 49-year-old man presented incapacity to exteriorize the glans penis. For erotic purposes, he had been using a rubber-enlarging band placed in the penile base for 6 years. With chronic use, he noticed that his penis swelled. Physical examination revealed lymphedema of the penis, phimosis and a stricture in the penile base. The patient was submitted to circumcision and the lymphedema remained stable 10 months postoperatively. Chronic penile incarceration usually causes penile lymphedema and urinary disturbance. Treatment consists of removal of foreign devices and surgical treatment of lymphedema.

    2016-01-27

    Neurofibrillary tangles (NFT) and β-amyloid plaques are the neurological hallmarks of both Alzheimer's disease and an unusual paralytic illness suffered by Chamorro villagers on the Pacific island of Guam. Many Chamorros with the disease suffer dementia, and in some villages one-quarter of the adults perished from the disease. Like Alzheimer's, the causal factors of Guamanian amyotrophic lateral sclerosis/parkinsonism dementia complex (ALS/PDC) are poorly understood. In replicated experiments, we found that chronic dietary exposure to a cyanobacterial toxin present in the traditional Chamorro diet, β-N-methylamino-l-alanine (BMAA), triggers the formation of both NFT and β-amyloid deposits similar in structure and density to those found in brain tissues of Chamorros who died with ALS/PDC. Vervets (Chlorocebus sabaeus) fed for 140 days with BMAA-dosed fruit developed NFT and sparse β-amyloid deposits in the brain. Co-administration of the dietary amino acid l-serine with l-BMAA significantly reduced the density of NFT. These findings indicate that while chronic exposure to the environmental toxin BMAA can trigger neurodegeneration in vulnerable individuals, increasing the amount of l-serine in the diet can reduce the risk.

  5. Chronic dysimmune neuropathies: Beyond chronic demyelinating polyradiculoneuropathy

    Directory of Open Access Journals (Sweden)

    Khadilkar Satish

    2011-01-01

    Full Text Available The spectrum of chronic dysimmune neuropathies has widened well beyond chronic demyelinating polyradiculoneuropathy (CIDP. Pure motor (multifocal motor neuropathy, sensorimotor with asymmetrical involvement (multifocal acquired demylinating sensory and motor neuropathy, exclusively distal sensory (distal acquired demyelinating sensory neuropathy and very proximal sensory (chronic immune sensory polyradiculopathy constitute the variants of CIDP. Correct diagnosis of these entities is of importance in terms of initiation of appropriate therapy as well as prognostication of these patients. The rates of detection of immune-mediated neuropathies with monoclonal cell proliferation (monoclonal gammopathy of unknown significance, multiple myeloma, etc. have been facilitated as better diagnostic tools such as serum immunofixation electrophoresis are being used more often. Immune neuropathies associated with malignancies and systemic vasculitic disorders are being defined further and treated early with better understanding of the disease processes. As this field of dysimmune neuropathies will evolve in the future, some of the curious aspects of the clinical presentations and response patterns to different immunosuppressants or immunomodulators will be further elucidated. This review also discusses representative case studies.

    Abstract Idiopathic chronic eosinophilic pneumonia (ICEP) is characterized by subacute or chronic respiratory and general symptoms, alveolar and/or blood eosinophilia, and peripheral pulmonary infiltrates on chest imaging. Eosinophilia is present in most cases, usually in excess of 1000/mm3. In absence of significant blood eosinophilia, a diagnosis of ICEP is supported by the demonstration of bronchoalveolar lavage eosinophilia. ICEP is typically associated with eosinophil counts higher than ...

    Fatty acid composition of the diet may influence cardiovascular risk from early childhood onwards. The objective of the present study was to perform a systematic review of dietary fat and fatty acid intakes in children and adolescents from different countries around the world and compare these with the population nutrient intake goals for prevention of chronic diseases as defined by the WHO (2003). Data on fat and fatty acid intake were mainly collected from national dietary surveys and from population studies all published during or after 1995. These were identified by searching PubMed, and through nutritionists at local Unilever offices in different countries. Fatty acid intake data from thirty countries mainly from developed countries were included. In twenty-eight of the thirty countries, mean SFA intakes were higher than the recommended maximum of 10 % energy, whereas in twenty-one out of thirty countries mean PUFA intakes were below recommended (6-10 % energy). More and better intake data are needed, in particular for developing regions of the world, and future research should determine the extent to which improvement of dietary fatty acid intake in childhood translates into lower CHD risk in later life. Despite these limitations, the available data clearly indicate that in the majority of the countries providing data on fatty acid intake, less than half of the children and adolescents meet the SFA and PUFA intake goals that are recommended for the prevention of chronic diseases.

    Full Text Available Abstract Background High intakes of phytochemical-rich foods have favorable effects on the prevention of chronic diseases. In this study we assessed the dietary phytochemical index (PI in relation to 3-year change in weight, waist circumference (WC, body adiposity index (BAI among Tehranian adults. Methods This longitudinal study was conducted in the framework of Tehran Lipid and Glucose Study, between 2006–2008 and 2009–2011, on 1938 adults, aged 19–70 y. The usual intake of participants was measured at baseline using a validated semi-quantitative food frequency questionnaire and dietary PI was calculated. Anthropometric measures were assessed both at baseline and 3 years later. Multiple regression models were used to estimate mean difference changes in anthropometrics associated with various dietary PI. Results The mean age of participants was 40.4 ± 13.0 y, at baseline, respectively. Mean weight gain was 1.49 ± 5.06 kg (1.65 ± 5.3 kg in men and 1.34 ± 4.9 kg in women during 3-year period. After adjustment for potential confounding variables including age at baseline, sex, BMI, educational levels, smoking, physical activity, total energy intake, dietary intake of carbohydrate, fat and protein, dietary intakes of whole grains in the highest quartile category of PI were inversely associated with 3-year changes in weight and WC (P for trend . Dietary intake of fruits in the highest quartile was also associated with lower weight gain during the study period (P for trend . There was significant inverse association between the highest quartile category of dietary PI with the 3-year changes in weight and BAI (P for trend . Conclusion Higher dietary PI could have favorable effects on prevention of weight gain and reduction of body adiposity in adults.

  10. Hypertension in Chronic Glomerulonephritis.

    Ihm, Chun-Gyoo

    2015-12-01

    Chronic glomerulonephritis (GN), which includes focal segmental glomerulosclerosis and proliferative forms of GN such as IgA nephropathy, increases the risk of hypertension. Hypertension in chronic GN is primarily volume dependent, and this increase in blood volume is not related to the deterioration of renal function. Patients with chronic GN become salt sensitive as renal damage including arteriolosclerosis progresses and the consequent renal ischemia causes the stimulation of the intrarenal renin-angiotensin-aldosterone system(RAAS). Overactivity of the sympathetic nervous system also contributes to hypertension in chronic GN. According to the KDIGO guideline, the available evidence indicates that the target BP should be ≤140mmHg systolic and ≤90mmHg diastolic in chronic kidney disease patients without albuminuria. In most patients with an albumin excretion rate of ≥30mg/24 h (i.e., those with both micro-and macroalbuminuria), a lower target of ≤130mmHg systolic and ≤80mmHg diastolic is suggested. The use of agents that block the RAAS system is recommended or suggested in all patients with an albumin excretion rate of ≥30mg/ 24 h. The combination of a RAAS blockade with a calcium channel blocker and a diuretic may be effective in attaining the target BP, and in reducing the amount of urinary protein excretion in patients with chronic GN.

    McCaskill, Michael L.; Hottor, Henry T.; Sapkota, Muna; Wyatt, Todd A.

    2016-01-01

    Background Slightly more than 5 % of the United States population heavily consumes ethanol, i.e., more than 14 drinks for men and 7 drinks for women a week. Chronic ethanol consumption can result in increased liver disease, reduced recovery from burn injury, and more frequent and severe respiratory infections. Chronic ethanol over-consumption also leads to vitamin D dysmetabolism and depletion. Vitamin D is a fat-soluble pro-hormone that regulates musculoskeletal health, cellular proliferation/differentiation, and innate and adaptive immune response. Methods In this study, C57BL/6 mice were fed 20 % ethanol in their water ad libitum for 7 weeks. Some mice were fed either a standard chow or a modified diet containing 0.15 μg/day of diallyl disulfide (DADS). Whole blood, lung tissue, and bronchial alveolar lavage fluid (BALF) were collected at sacrifice and analyzed for 25(OH) D3, 1,25 (OH)2D3, vitamin D receptor VDR, CYP2E1, and CYP27B1 levels. Results Ethanol reduced 25(OH) D3 and 1,25 (OH)2D3 in lung tissue and BALF on average 31 %. The largest ethanol-mediated reduction was in the 1,25 (OH)2D3 (42 %) measured in the BALF. Dietary supplementation of DADS restored BALF and lung tissue protein of 25(OH) D3 and 1,25(OH)2D3 to control levels. Chronic ethanol consumption also resulted in tissue increases of vitamin D response (VDR) protein, Cyp2E1, and reductions in vitamin D-activating enzyme CYP27B1. All three of these effects were attenuated by dietary supplementation of DADS. Conclusions In conclusion, the pulmonary metabolic disturbances mediated by chronic ethanol consumption as measured by 1,25(OH)2D3 protein levels, epithelial lining fluid, and lung tissue can be ameliorated by dietary supplementation of DADS in C57BL/6 mice.

  12. Nutrients, foods, dietary patterns and telomere length: Update of epidemiological studies and randomized trials.

    Identifying simple strategies to prevent or delay age-associated pathologies is a major public health concern. Attrition of telomeres, chromatin structures that help maintain genome stability, leads to cell death or senescence. Thus telomere length is a reliable hallmark of biological aging and the risk of developing age-related chronic diseases through common oxidation and inflammation mechanisms. Variability in telomere shortening that is independent of chronological age suggests that it is a modifiable factor, which may be explained in part by lifestyle variables such as smoking, adiposity, physical exercise, and diet. Here we summarize data from published studies focused on nutrition (nutrients, foods, and dietary patterns) and telomere length. Research on the topic is incipient and most data comes from epidemiologic studies, often cross-sectional in design. Consistent with well-known evidence of benefit or harm for chronic age-related diseases, dietary antioxidants and consumption of antioxidant-rich, plant-derived foods help maintain telomere length. In contrast, total and saturated fat intake and consumption of refined flour cereals, meat and meat products, and sugar-sweetened beverages relate to shorter telomeres. Data on alcohol and dairy products is controversial. There is evidence that adherence to the Mediterranean diet is associated with longer telomeres. Randomized clinical trials are limited to seafood-derived long-chain n-3 polyunsaturated fatty acids, with promising results. To fill the many gaps in our knowledge of the aging process and confirm nutrition as a useful tool to counteract biological aging more research is warranted, particularly observational studies using repeated measurements of telomere length and randomized trials of foods and dietary patterns with sequential telomere analyses.

    Hodge, James G; Barraza, Leila F

    2016-01-01

    In the United States, tens of thousands of Americans die each year of heart disease, stroke, or other chronic conditions tied to hypertension from long-term overconsumption of sodium compounds. Major strides to lower dietary sodium have been made over decades, but the goal of reducing Americans' daily consumption is elusive. The Food and Drug Administration (FDA) has been urged to consider stronger regulatory limits on sodium, especially in processed and prepared foods. Still, FDA categorizes salt (and many other sodium compounds) as "generally recognized as safe," meaning they can be added to foods when ingested in reasonable amounts. Legal reforms or actions at each level of government offer traditional and new routes to improving chronic disease outcomes. However, using law as a public health tool must be assessed carefully, given potential trade-offs and unproven efficacy. PMID:26890409

    Studies on the role of diet in the development of chronic diseases often rely on self-report surveys of dietary intake. Unfortunately, many validity studies have demonstrated that self-reported dietary intake is subject to systematic under-reporting, although the vast majority of such studies have been conducted in industrialised countries. The aim of the present study was to investigate whether or not systematic reporting error exists among the individuals of African ancestry (n 324) in five countries distributed across the Human Development Index (HDI) scale, a UN statistic devised to rank countries on non-income factors plus economic indicators. Using two 24 h dietary recalls to assess energy intake and the doubly labelled water method to assess total energy expenditure, we calculated the difference between these two values ((self-report - expenditure/expenditure) × 100) to identify under-reporting of habitual energy intake in selected communities in Ghana, South Africa, Seychelles, Jamaica and the USA. Under-reporting of habitual energy intake was observed in all the five countries. The South African cohort exhibited the highest mean under-reporting ( - 52·1% of energy) compared with the cohorts of Ghana ( - 22·5%), Jamaica ( - 17·9%), Seychelles ( - 25·0%) and the USA ( - 18·5%). BMI was the most consistent predictor of under-reporting compared with other predictors. In conclusion, there is substantial under-reporting of dietary energy intake in populations across the whole range of the HDI, and this systematic reporting error increases according to the BMI of an individual.

    Full Text Available Abstract Background Nonalcoholic fatty liver disease (NAFLD is a prevalent chronic liver disease in industrialized countries. The present study was undertaken to explore the preventive effect of dietary sea cucumber cerebroside (SCC extracted from Acaudina molpadioides in fatty liver rats. Methods Male Wistar rats were randomly divided into four groups including normal control group, NAFLD model group, and two SCC-treated groups with SCC at 0.006% and 0.03% respectively. The fatty liver model was established by administration of 1% orotic acid (OA to the rats. After 10d, serum and hepatic lipid levels were detected. And the serum alanine aminotransferase (ALT and aspartate aminotransferase (AST activities were also determined. Besides, to gain the potential mechanism, the changes of key enzymes and gene expressions related to the hepatic lipid metabolism were measured. Results Dietary SCC at the level of 0.006% and 0.03% ameliorated the hepatic lipid accumulation in fatty liver rats. SCC administration elevated the serum triglyceride (TG level and the ALT, AST activities in OA-fed rats. The activities of hepatic lipogenic enzymes including fatty acid synthase (FAS, malic enzyme (ME and glucose-6-phosphatedehydrogenase (G6PDH were inhibited by SCC treatment. And the gene expressions of FAS, ME, G6PDH and sterol-regulatory element binding protein (SREBP-1c were also reduced in rats fed SCC. However, dietary SCC didn't affect the activity and mRNA expression of carnitine palmitoyltransferase (CPT in liver. Besides, suppression of microsomal triglyceride transfer protein (MTP activity was observed in SCC-feeding rats. Conclusions These results suggested that dietary SCC could attenuate hepatic steatosis due to its inhibition of hepatic lipogenic gene expression and enzyme activity and the enhancement of TG secretion from liver.

    2016-08-01

    Focus groups (n = 7) were conducted with Chinese students (n = 43) studying in the USA to determine how acculturation and environmental factors influence dietary behavior and body mass index (BMI). This study used mixed methodology, collecting both qualitative (focus groups) and quantitative (24-h dietary recalls, food adoption scores, degree of acculturation, and height and weight measures) data. Themes emerging from focus group discussions were: a) dietary and social acculturation, b) factors influencing food intake, c) cultural importance of food, and d) changes in weight and BMI status. Environmental, behavioral, and cultural factors appear to have impacted the eating behaviors of the students. Because of the nature of the study, self-reported heights and weights were used to calculate BMI while living in China and actual heights and weights were taken for each student at the focus group to calculate current BMI after living in the USA. The majority of Chinese students (69% males; 85% females) experienced weight gain, resulting in an increased BMI based on weight/height data and as reported in focus group discussions. As a result, if students continue to gain weight, they may be at higher risk of developing chronic diseases in the future. Further, implemented dietary change may be transferred to other family members if students return to China. Results suggest that nutrition education should be provided to incoming foreign students during their orientation. PMID:27125431

    Osteoarthritis (OA) is a chronic, painful, degenerative and inflammatory disease that affects the synovial joints and leads finally to the loss of mobility. It is highly prevalent in dogs. Nowadays, no cure exists, and the pharmacological treatment is limited to clinical signs alleviation. Some positive beneficial effects have been highlighted with dietary supplements in the course of dog OA. The goals of this narrative review are to summarize the scientific data available in the literature on dietary supplements assessed in dog OA and to discuss some trails about how to improve several aspects of research and issues with dietary supplements, such as bioavailability and dosage regimen. Chondroitin sulphate, glucosamine, undenaturated type II collagen, avocado-soya bean unsaponifiables, curcumin and polyunsaturated fatty acids were studied in dog OA and therefore discussed in the present review. Most of them showed anticatabolic and anti-inflammatory effects. Unfortunately, few data exist concerning their pharmacokinetics. Their bioavailability is low, but new formulations are developed to enhance their gastrointestinal absorption. The clinical relevance of these new formulations compared to native forms should be demonstrated in good clinical trials. Even if further investigations are needed, dietary supplements should be considered in OA management. PMID:26205697

    We examined if stress associated changes in weight and dietary restraint are associated with changes in the composition of foods consumed. Participants were 38 healthy women on a taught postgraduate university course. Data were obtained at the beginning of the semester and 15 weeks later just prior to a written course exam (the stressor). By using a within subject design, we measured the composition of food consumed, body mass index (BMI), levels of dietary restraint and salivary cortisol. In the larger study from which these data were obtained, it was shown that the effect of increased cortisol secretion on weight gain was mediated by a reduction in dietary restraint. The present data show that increased cortisol secretion, reduced dietary restraint and increased caloric intake, account for 73% of the variance in change in BMI. Further regression analysis indicated that the change in dietary restraint mediated the effect of change in cortisol on change in BMI. Final analysis revealed that the effect of these changes in dietary restraint on weight are partially mediated by increased caloric intake from carbohydrate and saturated fat, that is, a change in dietary composition partially accounts for the link between increased cortisol secretion through heightened hypothalamic-pituitary-adrenal activity resulting in weight gain. These data are consistent with a 'comfort food hypothesis', as they suggest that chronic stress can promote reward associated behaviour through reduced dietary restraint and consumption of food containing more carbohydrate and saturated fat.
