    We aim to identify the prevalence of food insecurity and to ascertain the association between food insecurity and food intake. A cross-sectional survey. The study included users of a primary healthcare service in Belo Horizonte, Brazil, from 2013 to 2014. Socioeconomic, health, and food intake data were gathered using a questionnaire and the Brazilian Food Insecurity Scale. Individuals 20 years old or older (n = 2817). The prevalence of food insecurity among families with individuals under 18 years was 41.0%, and 26.4% in other households. After adjusting for potential confounders, the households in food insecurity with members under 18 years old, the consumption of fruits and vegetables (RP = 0.70, 95%IC: 0.58-0.84), and fruits (RP = 0.74, 95%IC: 0.59-0.93) was lower; and consumption of beans was higher (RP = 1.49, 95%IC: 1.06-2.09) compared to those with food security. In households without members under 18 years old, the consumption of fruits and vegetables (RP = 0.68, 95%IC: 0.58-0.79), fruits (RP = 0.61, 95%IC: 0.50-0.74), and beans (RP = 0.78, 95%IC: 0.63-0.97) was lower; and the consumption of tubers (RP = 1.36, 95%IC: 1.03-1.79) was higher. However, the state of food insecurity did not affect the consumption of ultra-processed foods, independently of age, sex, marital status, educational level, and employed status. Food insecurity negatively affected the fruit and vegetable consumption in both types of families tested. The consumption of beans was higher in households with children and adolescents, and the consumption of tubers was higher in households without children and adolescents. However, food insecurity did not change the intake of ultraprocessed foods. Copyright © 2018 Elsevier Inc. All rights reserved.

    Concern over micronutrient inadequacies in Uganda has prompted the introduction of mass fortification. To use food intake to determine nutrient inadequacies in children aged 24 to 59 months and nonpregnant women of reproductive age, and to model the adequacy of mass fortification. Data were collected by the 24-hour recall method in three regions. Usual nutrient intakes were calculated by adjusting actual intake distribution for the intraindividual variance. The impact of fortification on intake adequacy was simulated. The nutrients with the highest prevalence of inadequate intake across regions were vitamin A (30% to 99%), vitamin B12 (32% to 100%), iron (55% to 89%), zinc (18% to 82%), and calcium (84% to 100%). According to simulations, fortification of vegetable oil and sugar with vitamin A would reduce the prevalence of vitamin A inadequacy in the Western and Northern regions; in Kampala it would eliminate vitamin A inadequacy but would cause 2% to 48% of children to exceed the Tolerable Upper Intake Level (UL). The proposed fortification of wheat flour would reduce the prevalence of inadequate intakes of thiamine, riboflavin, folate, and niacin in Kampala, but would have little impact in the other two regions due to low flour consumption. Micronutrient fortification of vegetable oil and sugar in all regions and of wheat flour in Kampala would reduce the prevalence of micronutrient inadequacies. However, the wheat flour formulation should be modified to better meet requirements, and the vitamin A content in sugar should be reduced to minimize the risk of high intakes. Maize flour may be suitable for targeted fortification, but prior consolidation of the industry would be required for maize flour to become a good vehicle for mass fortification.

  3. Food intake of university students

    Full Text Available ABSTRACT This narrative literature review aimed to analyze the results of studies on the food intake of university students. A literature search was conducted in July 2014 and updated in July 2016 in the Scopus, MedLine/PubMed, and SciELO databases, using descriptors related to university students and food intake in English and Portuguese. Overall, 37 studies that analyzed university students’ food intake were included in this review, eight of which were conducted in Brazil. The results demonstrated that most university students have unhealthy eating behaviors, such as high intake of fast foods, snacks, sweets, soft drinks, and alcoholic beverages, and low intake of fruits, vegetables, fish, whole grains, and legumes. Undergraduate students of health sciences, such as nursing, nutrition, and medicine, did not have healthier diets. University students’ food intake was characterized as unhealthy, regardless of undergraduate program or sex, especially among students who left the parents’ home and became responsible for their own food. Therefore, there is a need of developing public policies that promote healthy eating habits among students, such as interventions to change their eating habits and increase their access to healthy foods at the university environment.

    Previous studies have focused on the effect of food advertisements on the caloric intake of children. However, the role of individual susceptibility in this effect is unclear. The aim of this study was to examine the role of impulsivity in the effect of advergames that promote energy-dense snacks on children's snack intake. First, impulsivity scores were assessed with a computer task. Then a randomized between-subject design was conducted with 261 children aged 7 to 10 years who played an advergame promoting either energy-dense snacks or nonfood products. As an extra manipulation, half of the children in each condition were rewarded for refraining from eating, the other half were not. Children could eat freely while playing the game. Food intake was measured. The children then completed questionnaire measures, and were weighed and measured. Overall, playing an advergame containing food cues increased general caloric intake. Furthermore, rewarding children to refrain from eating decreased their caloric intake. Finally, rewarding impulsive children to refrain from eating had no influence when they were playing an advergame promoting energy-dense snacks, whereas it did lead to reduced intake among low impulsive children and children who played nonfood advergames. Playing an advergame promoting energy-dense snacks contributes to increased caloric intake in children. The advergame promoting energy-dense snacks overruled the inhibition task to refrain from eating among impulsive children, making it more difficult for them to refrain from eating. The findings suggest that impulsivity plays an important role in susceptibility to food advertisements. Copyright © 2014 by the American Academy of Pediatrics.

  5. Slow food, fast food and the control of food intake.

    This Perspective focuses on two elements of our food supply and eating environment that facilitate high energy intake: a high eating rate and distraction of attention from eating. These two elements are believed to undermine our body's capacity to regulate its energy intake at healthy levels because they impair the congruent association between sensory signals and metabolic consequences. The findings of a number of studies show that foods that can be eaten quickly lead to high food intake and low satiating effects-the reason being that these foods only provide brief periods of sensory exposure, which give the human body insufficient cues for satiation. Future research should focus on the underlying physiological, neurological and molecular mechanisms through which our current eating environment affects our control of food intake.

    Though parental modeling is thought to play a critical role in promoting children's healthy eating, little research has examined maternal food intake and maternal food talk as independent predictors of children's food intake. The present study examines maternal food talk during a structured eating protocol, in which mothers and their children had the opportunity to eat a series of familiar and unfamiliar vegetables and desserts. Several aspects of maternal talk during the protocol were coded, including overall food talk, directives, pronoun use, and questions. This study analyzed the predictors of maternal food talk and whether maternal food talk and maternal food intake predicted children's food intake during the protocol. Higher maternal body mass index (BMI) predicted lower amounts of food talk, pronoun use, and questions. Higher child BMI z-scores predicted more first person pronouns and more wh-questions within maternal food talk. Mothers of older children used fewer directives, fewer second person pronouns, and fewer yes/no questions. However, maternal food talk (overall and specific types of food talk) did not predict children's food intake. Instead, the most robust predictor of children's food intake during this protocol was the amount of food that mothers ate while sitting with their children. These findings emphasize the importance of modeling healthy eating through action and have implications for designing interventions to provide parents with more effective tools to promote their children's healthy eating.

    Many questions must be considered with regard to consuming food, including when to eat, what to eat and how much to eat. Although eating is often thought to be a homeostatic behaviour, little evidence exists to suggest that eating is an automatic response to an acute shortage of energy. Instead, food intake can be considered as an integrated response over a prolonged period of time that maintains the levels of energy stored in adipocytes. When we eat is generally determined by habit, convenience or opportunity rather than need, and meals are preceded by a neurally-controlled coordinated secretion of numerous hormones that prime the digestive system for the anticipated caloric load. How much we eat is determined by satiation hormones that are secreted in response to ingested nutrients, and these signals are in turn modified by adiposity hormones that indicate the fat content of the body. In addition, many nonhomeostatic factors, including stress, learning, palatability and social influences, interact with other controllers of food intake. If a choice of food is available, what we eat is based on pleasure and past experience. This article reviews the hormones that mediate and influence these processes.

    Human exposure to cadmium (Cd) is associated with various diseases and high levels of Cd have been detected in Bangladeshi population warranting further research to identify the source of this exposure. In this study, Cd levels in 327 and 94 samples of Bangladeshi food and non-food samples, respectively, were determined using inductively coupled plasma mass spectrometry. This is the largest number of Bangladeshi food and nonfood samples investigated for their Cd content. High Cd levels were detected in leafy vegetables (mean 31 [SD 29]μg/kg). Of these vegetables, lal shak (Amaranthus tricolor) contained the highest Cd level (303 μg/kg [wet weight]; mean 100.5 [SD 95]μg/kg). Bangladeshi rice also showed significant concentration of Cd (mean 37.2 [SD 30]μg/kg). Of particular concern is the very high level of Cd detected in some puffed rice, which we attribute to the illegal practice of using urea for whitening the puffed rice. Tobacco leaves, which are commonly consumed during betel quid chewing by Bangladeshis, contain significant levels of Cd (mean 95 [SD 87]μg/kg). The total daily intake (TDI) of Cd from foods for Bangladeshis was estimated to be 34.55 μg/d. This is rather high when compared to the TDI of Cd for other populations. Our analysis reveals that this is mainly due to the very high intake of rice and vegetables, and lower consumption of animal products (which are low in Cd), by the Bangladeshis. We also determined the provisional maximum tolerable daily intake and target hazard quotients values for Cd. Clearly a more balanced diet is necessary to reduce the Cd intake in the Bangladeshi population, especially by reducing the very high intake of rice and certain leafy vegetables. Food manufacturing and agricultural practices needs to be altered to reduce the entry of Cd into the food chain. Exposure to high levels of Cd can be harmful to human health and this study provides a comprehensive analysis of Cd levels in a variety of food items from

    in their biosynthesis in specific tissues are not clarified. It has been suggested that endogenous anandamide could stimulate food intake by activation of cannabinoid receptors in the brain and/or in the intestinal tissue. On the other hand, endogenous OEA and PEA have been suggested to inhibit food intake by acting...... on receptors in the intestine. At present, there is no clear role for endogenous anandamide in controlling food intake via cannabinoid receptors, neither centrally nor in the gastrointestinal tract. However, OEA, PEA and perhaps also LEA may be involved in regulation of food intake by selective prolongation...... OEA is less clear. Prolonged intake of dietary fat (45 energy%) may promote over-consumption of food by decreasing the endogenous levels of OEA, PEA and LEA in the intestine....

    Malnutrition is common in acute care hospitals. During hospitalization, poor appetite, medical interventions, and food access issues can impair food intake leading to iatrogenic malnutrition. Nutritional support is a common intervention with demonstrated effectiveness. "Food first" approaches have also been developed and evaluated. This scoping review identified and summarized 35 studies (41 citations) that described and/or evaluated dietary, foodservice, or mealtime interventions with a food first focus. There were few randomized control trials. Individualized dietary treatment leads to improved food intake and other positive outcomes. Foodservices that promote point-of-care food selection are promising, but further research with food intake and nutritional outcomes is needed. Protected mealtimes have had insufficient implementation, leading to mixed results, while mealtime assistance, particularly provided by volunteers or dietary staff, appears to promote food intake. A few innovative strategies were identified but further research to develop and evaluate food first approaches is needed.

  14. [Food intake regulation - 2nd part].

    The review article summarizes the principles of hedonic regulation of food intake which represents the food intake independent on the maintenance of homeostasis. The theory describing hedonic regulation, so called Incentive Salience Theory, comprises three major processes: liking (positive attribution to food stimulus), wanting (motivation to gain it) and learning (identification of these stimuli and distinguishing them from those connected with aversive reaction). Neuronal reward circuits are the anatomical and functional substrates of hedonic regulation. They react to gustatory and olfactory (or visual) stimuli associated with food intake. A food item is preferred in case its consumption is connected with a pleasant feeling thus promoting the behavioural reaction. The probability of this reaction after repetitive exposure to such a stimulus is increased (learned preference). On the contrary, learned aversion after repetitive exposure is connected with avoidance of a food item associated with a negative feeling. Main mediators of hedonic regulation are endocannabinoids, opioids and monoamines (dopamine, serotonin). Dopamine in dorsal striatum via D2 receptors generates food motivation as a key means of survival, however in ventral striatum (nucleus accumbens) is responsible for motivation to food bringing pleasure. Serotonin via its receptors 5-HT1A a T-HT2C decreases intake of palatable food. It plays a significant role in the pathogenesis of eating disorders, particularly mental anorexia. There, a food restriction represents a kind of automedication to constitutionally pathologically increased serotonin levels. Detailed understanding of processes regulating food intake is a key to new pharmacological interventions in eating disorders.

    The digital photography of foods method accurately estimates the food intake of adults and children in cafeterias. When using this method, images of food selection and leftovers are quickly captured in the cafeteria. These images are later compared with images of 'standard' portions of food using computer software. The amount of food selected and discarded is estimated based upon this comparison, and the application automatically calculates energy and nutrient intake. In the present review, we describe this method, as well as a related method called the Remote Food Photography Method (RFPM), which relies on smartphones to estimate food intake in near real-time in free-living conditions. When using the RFPM, participants capture images of food selection and leftovers using a smartphone and these images are wirelessly transmitted in near real-time to a server for analysis. Because data are transferred and analysed in near real-time, the RFPM provides a platform for participants to quickly receive feedback about their food intake behaviour and to receive dietary recommendations for achieving weight loss and health promotion goals. The reliability and validity of measuring food intake with the RFPM in adults and children is also reviewed. In sum, the body of research reviewed demonstrates that digital imaging accurately estimates food intake in many environments and it has many advantages over other methods, including reduced participant burden, elimination of the need for participants to estimate portion size, and the incorporation of computer automation to improve the accuracy, efficiency and cost-effectiveness of the method. © 2013 The British Dietetic Association Ltd.

    The maintenance of the body weight at a stable level is a major determinant in keeping the higher animals and mammals survive. Th e body weight depends on the balance between the energy intake and energy expenditure. Increased food intake over the energy expenditure of prolonged time period results in an obesity. Th e obesity has become an important worldwide health problem, even at low levels. The obesity has an evil effect on the health and is associated with a shorter life expectancy. A complex of central and peripheral physiological signals is involved in the control of the food intake. Centrally, the food intake is controlled by the hypothalamus, the brainstem, and endocannabinoids and peripherally by the satiety and adiposity signals. Comprehension of the signals that control food intake and energy balance may open a new therapeutic approaches directed against the obesity and its associated complications, as is the insulin resistance and others. In conclusion, the present review summarizes the current knowledge about the complex system of the peripheral and central regulatory mechanisms of food intake and their potential therapeutic implications in the treatment of obesity.

Linda Rinaman and Yvonne Ulrich-Lai at the 2014 Neurobiology of Stress Workshop held in Cincinnati, OH. This symposium comprised research presentations by four neuroscientists whose work focuses on the biological bases for complex interactions among stress, food intake and emotion. First, Dr. Ulrich-Lai describes her rodent research exploring mechanisms by which the rewarding properties of sweet palatable foods confer stress relief. Second, Dr. Stephanie Fulton discusses her work in which excessive, long-term intake of dietary lipids, as well as their subsequent withdrawal, promotes stress-related outcomes in mice. Third, Dr. Mark Wilson describes his group’s research examining the effects of social hierarchy-related stress on food intake and diet choice in group-housed female rhesus macaques, and compared the data from monkeys to results obtained in analogous work using rodents. Lastly, Dr. Gorica Petrovich discusses her research program that is aimed at defining cortical–amygdalar–hypothalamic circuitry responsible for curbing food intake during emotional threat (i.e., fear anticipation) in rats. Their collective results reveal the complexity of physiological and behavioral interactions that link stress, food intake and emotional state, and suggest new avenues of research to probe the impact of genetic, metabolic, social, experiential, and environmental factors.

    The degree of food insecurity and dietary intake was examined in adult Colombians who are new immigrants to Canada and use a food bank. In-person surveys were conducted on a convenience sample of 77 adult Colombian immigrant food bank users in London, Ontario. Degree of food insecurity was measured by the Radimer/Cornell questionnaire, food intakes by 24-hour recall, sociodemographics, and questionnaires about changes in dietary patterns before and after immigration. Thirty-six men and 41 women participated in the study. Despite being highly educated, all respondents had experienced some form of food insecurity within the previous 30 days. The degree of food insecurity seems to be inversely associated with income and length of residency in Canada. Total daily energy intake was low, with a mean value of 1,568.3 +/- 606.0 kcal (6,217.5 +/- 2,336.4 kJ). In particular, a large proportion of participants consumed a diet low in fruits and vegetables (73%) and milk and dairy products (58%). Colombian immigrant food bank users new to Canada experience various degrees of food insecurity, which is associated with inadequate food intake. Interventions are needed to assist this population with adapting to society while concurrently sustaining healthy eating patterns.

The post-lunch questionnaire included questions about body mass index, exercise habits, motivation and dietary restraint. Results Participants exposed to exercise commercials reduced their caloric intake by 21.7% relative to the control condition. Additionally, watching exercise messages increased the perceived healthiness and liking of the meal. Although exercise habits and intentions did not moderate the effect of commercial condition on food intake, we also found that this intake reduction was driven by participants with higher body mass index levels. Conclusions These results imply that exercise messages may serve as a reminder of the link between food and physical activity and affect food consumption. It also highlights the need for increased awareness that these messages have powerful influences not only on exercise behavior, but also on closely related behaviors such as eating.

    Past research has shown that promotional messages such as food advertising influence food consumption. However, what has gone largely unexplored is the effect of exercise advertising on food intake. This study experimentally tested the effects of exposure to exercise commercials on food intake at a lunch meal as compared to the effects of control commercials. Prior to eating lunch, 125 participants (71 women, 54 men) watched 8 commercials, either all related to exercise or fitness (n=67) or neutral products (i.e. car insurance) (n=58). The meal consisted of a pasta dish with tomato sauce, salad and chocolate pudding. The post-lunch questionnaire included questions about body mass index, exercise habits, motivation and dietary restraint. Participants exposed to exercise commercials reduced their caloric intake by 21.7% relative to the control condition.

    In life-cycle assessment, the functional unit defines the unit for calculation of environmental indicators. The objective of the present study was to assess the influence of two functional units, 100 g and 100 kcal (420 kJ), on the associations between three dimensions for identifying sustainable foods, namely environmental impact (via greenhouse gas emissions (GHGE)), nutritional quality (using two distinct nutrient profiling systems) and price. GHGE and price data were collected for individual foods, and were each expressed per 100 g and per 100 kcal. Two nutrient profiling models, SAIN,LIM and UK Ofcom, were used to assess foods' nutritional quality. Spearman correlations were used to assess associations between variables. Sustainable foods were identified as those having more favourable values for all three dimensions. The French Individual and National Dietary Survey (INCA2), 2006-2007. Three hundred and seventy-three foods highly consumed in INCA2, covering 65 % of total energy intake of adult participants. When GHGE and price were expressed per 100 g, low-GHGE foods had a lower price and higher SAIN,LIM and Ofcom scores (r=0·59, -0·34 and -0·43, respectively), suggesting a compatibility between the three dimensions; 101 and 100 sustainable foods were identified with SAIN,LIM and Ofcom, respectively. When GHGE and price were expressed per 100 kcal, low-GHGE foods had a lower price but also lower SAIN,LIM and Ofcom scores (r=0·67, 0·51 and 0·47, respectively), suggesting that more environment-friendly foods were less expensive but also less healthy; thirty-four sustainable foods were identified with both SAIN,LIM and Ofcom. The choice of functional unit strongly influenced the compatibility between the sustainability dimensions and the identification of sustainable foods.

    Many methods for monitoring diet and food intake rely on subjects self-reporting their daily intake. These methods are subjective, potentially inaccurate and need to be replaced by more accurate and objective methods. This paper presents a novel approach that uses an electroglottograph (EGG) device for an objective and automatic detection of food intake. Thirty subjects participated in a four-visit experiment involving the consumption of meals with self-selected content. Variations in the electrical impedance across the larynx caused by the passage of food during swallowing were captured by the EGG device. To compare performance of the proposed method with a well-established acoustical method, a throat microphone was used for monitoring swallowing sounds. Both signals were segmented into non-overlapping epochs of 30 s and processed to extract wavelet features. Subject-independent classifiers were trained, using artificial neural networks, to identify periods of food intake from the wavelet features. Results from leave-one-out cross validation showed an average per-epoch classification accuracy of 90.1% for the EGG-based method and 83.1% for the acoustic-based method, demonstrating the feasibility of using an EGG for food intake detection.

    Most adults do not meet calcium intake recommendations. Little is known about how individual and family factors, including parenting practices that influence early adolescents' intake of calcium-rich foods, affect calcium intake of parents. This information could inform the development of effective nutrition education programs. To identify individual and family factors associated with intake of calcium-rich foods among parents of early adolescents (aged 10 to 13 years). A cross-sectional survey was used with 14 scales to assess attitudes/preferences and parenting practices regarding calcium-rich foods and a calcium-specific food frequency questionnaire (2006-2007). A convenience sample of self-reporting non-Hispanic white, Hispanic, and Asian (n=661) parents was recruited in nine states. Parents were the primary meal planner/preparer and completed questionnaires in homes or community settings. Predictors of calcium intake from three food groupings-all food sources, dairy foods, and milk. Multivariate regression analyses identified demographic, attitude/preference, and behavioral factors associated with calcium intake. Most respondents were women (∼90%) and 38% had a college degree. Education was positively associated with calcium intake from all three food groupings, whereas having an Asian spouse compared to a non-Hispanic white spouse was negatively associated with calcium intake only from all food sources and from dairy foods. Expectations for and encouragement of healthy beverage intake for early adolescents were positively associated with calcium intake from dairy foods and milk, respectively. Parental concern regarding adequacy of intake was negatively associated, whereas perception of health benefits from calcium-rich foods was positively associated with calcium intake from all food sources and from dairy foods. Between 20% and 32% of the variance in calcium intake from all food groupings was explained in these models. Individual factors and positive

    2016-01-01

    The sensory experience of eating is an important determinant of food intake control, often attributed to the positive hedonic response associated with certain sensory cues. However, palatability is just one aspect of the sensory experience. Sensory cues based on a food's sight, smell, taste and texture are operational before, during and after an eating event. The focus of this review is to look beyond palatability and highlight recent advances in our understanding of how certain sensory characteristics can be used to promote better energy intake control. We consider the role of visual and odour cues in identifying food in the near environment, guiding food choice and memory for eating, and highlight the ways in which tastes and textures influence meal size and the development of satiety after consumption. Considering sensory characteristics as a functional feature of the foods and beverages we consume provides the opportunity for research to identify how sensory enhancements might be combined with energy reduction in otherwise palatable foods to optimize short-term energy intake regulation in the current food environment. Moving forward, the challenge for sensory nutritional science will be to assess the longer-term impact of these principles on weight management. © 2015 World Obesity.

    The well-documented increases in obesity and unhealthy dietary practices substantiate the need for evidence-based tools that can help people improve their dietary habits. The current spread of mobile phone-embedded cameras offers new opportunities for recording food intake. Moreover, the act of taking pictures of food consumed may enhance visual consciousness of food choice and quantity. The present study aimed to assess the effect of using cell phone pictures to record food intake on energy intake and food choice in college students. The effectiveness and acceptability of cell phone picture-based diet recording also was assessed. A repeated measures crossover design was used. One group of participants entered their food intake online during 3 days based on their memory, although a second group recorded their food intake using cell phone pictures as their reference. Participants then crossed over to complete 3 more days of diet recording using the alternate method. Focus groups were conducted to obtain feedback on the effectiveness and acceptability of cell phone picture-based diet recording. Intake of meat and vegetable servings were significantly higher in the memory period compared with the cell phone period, regardless of the order. Results from the focus group indicated a positive attitude toward the use of cell phone pictures in recording food intake and an increased awareness of food choice and portion size. Cell phone pictures may be an easy, relevant, and accessible method of diet self-monitoring when aiming at dietary changes. Future trials should combine this technique with healthy eating education. © 2015 Sigma Theta Tau International.

    Full Text Available Water is essential for the proper functioning of the body. Even though a recommendation exists for adequate water intake for Koreans, studies identifying actual water intake from all beverages and foods consumed daily in the Korean population are limited. Thus, we estimated total water intake from both beverages and foods and its association with energy intake and eating behaviors in Korean adults. We used a nationally representative sample of 25,122 Korean adults aged ≥19 years, from the Korean National Health and Nutrition Examination Survey 2008–2012. We performed multiple regression analyses, adjusting for sociodemographic and health-related variables to investigate the contribution of overall energy and dietary intakes and eating behaviors to total water intake. The mean total water intake excluding plain water was 1071 g (398 g from beverages and 673 g from foods and the estimated plain water intake was 1.3 L. Among Korean adults, 82% consumed beverages (excluding plain water and these beverages contributed to 10% of daily energy intake and 32% of total water intake from beverages and foods. For every 100 kcal/day in energy intake, water intake consumed through beverages and foods increased by 18 g and 31 g, respectively. Water intake from beverages and foods was positively associated with energy from fat and dietary calcium, but inversely associated with energy density and energy from carbohydrates. When there was a 5% increase in energy intake from snacks and eating outside the home, there was an increase in water intake from beverages of 13 g and 2 g, respectively. Increased daily energy intake, the number of eating episodes, and energy intake from snacks and eating outside the home predicted higher water intake from beverages and foods.

    Data-reduction methods such as principal component analysis are often used to derive dietary patterns. However, such methods do not assess how foods are consumed in relation to each other. Gaussian graphical models (GGMs) are a set of novel methods that can address this issue. We sought to apply GGMs to derive sex-specific dietary intake networks representing consumption patterns in a German adult population. Dietary intake data from 10,780 men and 16,340 women of the European Prospective Investigation into Cancer and Nutrition (EPIC)-Potsdam cohort were cross-sectionally analyzed to construct dietary intake networks. Food intake for each participant was estimated using a 148-item food-frequency questionnaire that captured the intake of 49 food groups. GGMs were applied to log-transformed intakes (grams per day) of 49 food groups to construct sex-specific food networks. Semiparametric Gaussian copula graphical models (SGCGMs) were used to confirm GGM results. In men, GGMs identified 1 major dietary network that consisted of intakes of red meat, processed meat, cooked vegetables, sauces, potatoes, cabbage, poultry, legumes, mushrooms, soup, and whole-grain and refined breads. For women, a similar network was identified with the addition of fried potatoes. Other identified networks consisted of dairy products and sweet food groups. SGCGMs yielded results comparable to those of GGMs. GGMs are a powerful exploratory method that can be used to construct dietary networks representing dietary intake patterns that reveal how foods are consumed in relation to each other. GGMs indicated an apparent major role of red meat intake in a consumption pattern in the studied population. In the future, identified networks might be transformed into pattern scores for investigating their associations with health outcomes. © 2016 American Society for Nutrition.

    Food insecurity has detrimental effects on the mental, physical, and behavioral health of developing children. Few studies, however, have sought to determine whether associations exist between food insecurity and intake of vegetables, fresh or canned fruit, candy or cookies, French fries, fast food, water, milk, fruit juices, fruit drinks, soda, and sports drinks. To identify independent associations that exist between maternal food insecurity and food and drink intake among toddlers, population-based data from the 2006-2008 Oregon Pregnancy Risk Assessment Monitoring System follow-back survey (Oregon PRAMS-2) of 1,522 mothers of 2-year-old children were analyzed. Maternal food insecurity was defined as mothers' report of eating less because of lack of money for food. Typical weekly child food and drink intake was examined using polytomous logistic regression: 0-1 days/week, 2-3 days/week, and 4-7 days/week. Maternal food insecurity prevalence was 11.7 %. Compared to toddlers of food secure mothers, toddlers of food insecure mothers consumed vegetables (adjusted odds ratio [AOR] for 4-7 days/week = 0.31; 95 % confidence interval [CI] 0.12, 0.79) and fruit (AOR for 4-7 days/week = 0.25; 95 % CI 0.08, 0.75) fewer days of the week. Toddlers of food insecure mothers consumed soda (AOR for 4-7 days/week = 3.21; 95 % CI 1.12, 9.14) more days of the week. Maternal food insecurity is associated with weekly intake of certain foods and drinks. Among toddlers, consumption of fewer vegetables and fruit, and more soda may help explain the link between food insecurity and poor health.

    The relation between mother's diet and breastmilk composition is still an open issue. Nutritional inadequacies during lactation may affect the well-being of both the mother and the infant. For this reason breast feeding women usually pay attention about their alimentary practices and about their style of life during breast-feeding period. This research was conducted to verify the adequacy of lactating mother's diet in comparison with the Italian recommended daily assumption levels of nutrients (LARN 1996) for this category. We have also compared food intake of not breast feeding mothers with the LARN, and analyzed the differences between these groups of mothers. Forty-eight healthy infants were selected, 23 bottle fed, 25 breast fed. Mothers's diet in the previous 48 hours was investigated using a structured questionnaire. The data collected were processed using software Dietosystem to obtain the daily nutrient intakes. The wetnurses's diet in comparison with the LARN 1996 resulted hypocaloric and hyperproteic, deficient in Calcium, Iron, folic acid and vitamin E. Surprisingly not breast feeding mothers's intake of nutrients is closer to LARN levels than that of breast feeding mothers. Mothers are not informed enough about their alimentation during lactating period. Pediatricians must improve their knowledge about this subject and give the mothers the information they need to achieve the recommended food requirements.

    Full Text Available The aim of the present study was to record the percentage of children, adults and elderly women in Greece meeting food and micronutrient intake recommendations. Additionally, the present study was aiming to identify the main food contributors of micronutrient intakes and assess the degree up to which meeting food intake recommendations also ensures micronutrient intake adequacy. Dietary intake data from three studies conducted in Greece (on 9–13-year-old children; 40–60-year-old adults; and 50–75-year-old women were used to estimate mean intakes, the percentages of subjects meeting food and nutrient intake recommendations and the contribution of six core food groups to nutrient intake adequacy. The present study showed that more than 50% of children, adults and elderly women were failing to consume the recommended portions of vegetables, dairy and grains. Furthermore, children and adults consuming the recommended portions of individual core food groups had significantly lower percentages of inadequate micronutrient intakes compared to their counterparts not meeting food intake recommendations (p < 0.05. Nevertheless, even among those consuming the recommended portions from a specific core food group, the recommended intake of the corresponding micronutrient (for which this food group is the main contributor was not always met. Indicatively, 18.2%–44.1% and 4.2%–7.0% of the populations under study were not meeting calcium and vitamin C intake recommendations, although they were consuming the recommended portions of dairy and fruits, respectively. In conclusion, these findings highlight the importance for public health policy makers to take all necessary initiatives to support the population in achieving the recommended intakes from all core food groups, but also emphasize on food variety to ensure adequate intake for all micronutrients.

  7. Impact of Perceived Healthiness of Food on Food Choices and Intake.

    Healthy eating is an important determinant of health, but adherence to dietary guidelines remains a public health concern. Identifying factors that impact dietary habits is therefore important to facilitate healthy eating. One widely used strategy to help consumers make healthier food choices is nutrition information, such as labeling and claims. Despite the intention of these strategies to improve decision making, they can also be misunderstood or misinterpreted by consumers. The aim of this review is to explore food perceptions by examining how cognitive factors influence perceived healthiness of food, and the impact of perceived healthiness of food on food choices and intake. Overall findings of this review suggest that cognitive factors, such as type of food and branding, significantly contribute to judgmental bias and have an impact on perceived healthiness while not consistently or systematically influencing choice and intake.

  8. Divergent circuitry underlying food reward and intake effects of ghrelin: dopaminergic VTA-accumbens projection mediates ghrelin's effect on food reward but not food intake.

    Obesity has reached global epidemic proportions and creating an urgent need to understand mechanisms underlying excessive and uncontrolled food intake. Ghrelin, the only known circulating orexigenic hormone, potently increases food reward behavior. The neurochemical circuitry that links ghrelin to the mesolimbic reward system and to the increased food reward behavior remains unclear. Here we examine whether VTA-NAc dopaminergic signaling is required for the effects of ghrelin on food reward and intake. In addition, we examine the possibility of endogenous ghrelin acting on the VTA-NAc dopamine neurons. A D1-like or a D2 receptor antagonist was injected into the NAc in combination with ghrelin microinjection into the VTA to investigate whether this blockade attenuates ghrelin-induced food reward behavior. VTA injections of ghrelin produced a significant increase in food motivation/reward behavior, as measured by sucrose-induced progressive ratio operant conditioning, and chow intake. Pretreatment with either a D1-like or D2 receptor antagonist into the NAc, completely blocked the reward effect of ghrelin, leaving chow intake intact. We also found that this circuit is potentially relevant for the effects of endogenously released ghrelin as both antagonists reduced fasting (a state of high circulating levels of ghrelin) elevated sucrose-motivated behavior but not chow hyperphagia. Taken together our data identify the VTA to NAc dopaminergic projections, along with D1-like and D2 receptors in the NAc, as essential elements of the ghrelin responsive circuits controlling food reward behavior. Interestingly results also suggest that food reward behavior and simple intake of chow are controlled by divergent circuitry, where NAc dopamine plays an important role in food reward but not in food intake.

    Food composition databases (FCDBs) provide detailed information about the nutritional composition of foods. The conversion of food consumption into nutrient intake need a Food composition database (FCDB) which lists the mean nutritional values for a given food portion. The limitations of FCDBs are sometimes little known by the users. Multicentre studies have raised several methodology challenges which allow to standardize nutritional assessments in different populations and geographical areas for food composition and nutrient intake. Differences between FCDBs include those attributed to technical matters, such as description of foods, calculation of energy and definition of nutrients, analytical methods, and principles for recipe calculation. Such differences need to be identified and eliminated before comparing data from different studies, especially when dietary data is related to a health outcome. There are ongoing efforts since 1984 to standardize FCDBs over the world (INFOODS, EPIC, EuroFIR, etc.). Food composition data can be gathered from different sources like private company analysis, universities, government laboratories and food industry. They can also be borrowed from scientific literature or even from the food labelling. There are different proposals to evaluate the quality of food composition data. For the development of a FCDB it is fundamental document in the most detailed way, each of the data values of the different components and nutrients of a food. The objective of AECOSAN (Agencia Española de Consumo Seguridad Alimentaria y Nutrición) and BEDCA (Base de Datos Española de Composición de Alimentos) association was the development and support of a reference FCDB in Spain according to the standards to be defined in Europe. BEDCA is currently the only FCDB developed in Spain with compiled and documented data following EuroFIR standards. Copyright AULA MEDICA EDICIONES 2015. Published by AULA MEDICA.

  11. The bogus taste test: Validity as a measure of laboratory food intake

    OpenAIRE

    Because overconsumption of food contributes to ill health, understanding what affects how much people eat is of importance. The ?bogus? taste test is a measure widely used in eating behaviour research to identify factors that may have a causal effect on food intake. However, there has been no examination of the validity of the bogus taste test as a measure of food intake. We conducted a participant level analysis of 31 published laboratory studies that used the taste test to measure food inta...

  12. Reward systems and food intake: role of opioids.

    Humans eat for many reasons, including the rewarding qualities of foods. A host of neurotransmitters have been shown to influence eating behavior and some of these appear to be involved in reward-induced eating. Endogenous opioid peptides and their receptors were first reported more than 30 years ago, and studies suggesting a role of opioids in the regulation of food intake date back nearly as far. Opioid agonists and antagonists have corresponding stimulatory and inhibitory effects on feeding. In addition to studies aimed at identifying the relevant receptor subtypes and sites of action within the brain, there has been a continuing interest in the role of opioids on diet/taste preferences, food reward, and the overlap of food reward with others types of reward. Data exist that suggest a role for opioids in the control of appetite for specific macronutrients, but there is also evidence for their role in the stimulation of intake based on already-existing diet or taste preferences and in controlling intake motivated by hedonics rather than by energy needs. Finally, various types of studies indicate an overlap between mechanisms mediating drug reward and palatable food reward. Preference or consumption of sweet substances often parallels the self-administration of several drugs of abuse, and under certain conditions, the termination of intermittent access to sweet substances produces symptoms that resemble those observed during opiate withdrawal. The overconsumption of readily available and highly palatable foods likely contributes to the growing rates of obesity worldwide. An understanding of the role of opioids in mediating food reward and promoting the overconsumption of palatable foods may provide insights into new approaches for preventing obesity.

    Television viewing may contribute to obesity via promotion of sedentary behavior and exposure to food-related commercials. However, the mechanisms by which food-related commercials promote food intake are not well understood. Therefore, the purpose of the present study was to examine the impact of television advertisements on food intake according to sex and transportability, or the tendency to become engrossed in what one is viewing. Eighty-three undergraduate students, free of disordered eating symptoms, were stratified by sex and randomly assigned to one of three conditions (food-related advertisements, neutral advertisements, or no advertisements). They were then identified as high or low in transportability according to a median split. A significant interaction was found between advertisement condition and transportability such that those high in transportability ate more in the food than other advertisement conditions. A second interaction was found between sex and transportability with women high in transportability eating more food than women low in transportability irrespective of advertisement condition. No significant main effects of advertisement condition, sex, or transportability were found. Results suggest the importance of studying the impact of individual difference variables on the relationship between food-related advertising and food intake. Copyright © 2013 Elsevier Ltd.

    The National Health and Nutrition Survey 2006 (ENSANUT in Spanish) reported high rates of under-nutrition in children of Yucatan. Is food intake the main cause of under-nutrition in children of the state of Yucatan, Mexico? Identify the primary causes of under-nutrition in pre-school children in Yucatan. A sample of 111 children (59 girls and 52 boys) aged 1-4 years representing Yucatan was taken from a database of ENSANUT 2006 and another national survey, a federal poverty mitigation programme for the state of Yucatan, Mexico entitled "Oportunidades". A human ecology approach together with life history theory was used to analyse anthropometric indices and food intake data from the ENSANUT 2006 and "Oportunidades". Height and weight were significantly correlated to age and total food intake. No correlations were found between age and anthropometric indices or food intake rates. The children in the sample had adequate protein intake but deficient energy intake. No correlation was identified between nutritional status and food intake rates. Pre-schoolers with higher weight-for-height values achieved greater height-for-age. These relationships can be explained by life history theory in that energy intake was used either for maintenance (combating and recovering from infections) or growth. The poor relationship between food intake rates and nutritional status is probably explained by the interaction between high disease incidence and insufficient energy intake. These conditions are endemic in Yucatan due to widespread poor housing, water and sanitation conditions.

    An absence of food literacy measurement tools makes it challenging for nutrition practitioners to assess the impact of food literacy on healthy diets and to evaluate the outcomes of food literacy interventions. The objective of the present scoping review was to identify the attributes of food literacy. A scoping review of peer-reviewed and grey literature was conducted and attributes of food literacy identified. Subjects included in the search were high-risk groups. Eligible articles were limited to research from Canada, USA, the UK, Australia and New Zealand. The search identified nineteen peer-reviewed and thirty grey literature sources. Fifteen identified food literacy attributes were organized into five categories. Food and Nutrition Knowledge informs decisions about intake and distinguishing between 'healthy' and 'unhealthy' foods. Food Skills focuses on techniques of food purchasing, preparation, handling and storage. Self-Efficacy and Confidence represent one's capacity to perform successfully in specific situations. Ecologic refers to beyond self and the interaction of macro- and microsystems with food decisions and behaviours. Food Decisions reflects the application of knowledge, information and skills to make food choices. These interdependent attributes are depicted in a proposed conceptual model. The lack of evaluated tools inhibits the ability to assess and monitor food literacy; tailor, target and evaluate programmes; identify gaps in programming; engage in advocacy; and allocate resources. The present scoping review provides the foundation for the development of a food literacy measurement tool to address these gaps.

  17. Impression management and food intake. Current directions in research.

    Vartanian, Lenny R

    2015-03-01

    This paper reviews recent research on consumption stereotypes (judgments of others based on what they eat) and impression management (modifying one's eating behavior in order to create a particular impression). A major recent focus in the literature has been on masculinity and meat eating, with research showing that meat is strongly associated with masculinity, and that individuals who follow a meat-based diet are perceived as more masculine than are individuals who follow a vegetarian diet. Although direct evidence for impression management through food intake remains sparse, a number of methodological approaches (including priming techniques and ecological valid assessments) are described that could be used in future research to identify the motives underlying people's eating behavior. Consumption stereotypes and impression management may be important influences on people's eating behavior, but the complexities of how, when, and for whom these factors influence food intake are still not well understood.

    Strategies are needed to address the shortfall in children's dairy food and Ca intakes. The present review identified interventions targeting an increase in children's dairy food or Ca intakes, and determined characteristics associated with successful intervention. A systematic literature search identified fourteen intervention studies, published in English, between 1990 and 2010. Studies were evaluated for study population, setting and mode of delivery, dietary targets and outcome measures, measures of intervention intensity, intervention description, the use of behaviour change techniques and intervention effectiveness. Interventions targeting an increase in dairy food or Ca intake. Children aged 5-12 years. Ten of the fourteen studies were considered to be effective. Studies focusing on encouraging intake of dairy foods or Ca alone were all effective, compared with 55 % of studies promoting dairy within the context of a healthy diet. Effective interventions tended to be higher in intensity, provide dairy foods and were delivered across a variety of settings to a range of primary targets. The number of behaviour change techniques used did not differentiate effective and ineffective interventions, but the use of taste exposure and prompting practice appeared to be important for effective intervention. Interventions that target an increase in children's dairy food or Ca intake could potentially increase children's dairy food intake by about one serving daily. Research conducted outside the USA is needed. The review has identified some promising strategies likely to be part of effective interventions for improving dairy and Ca intakes in countries where children's intake is insufficient.

    The aim of this study was to investigate whether food reward plays a role in the stimulating effect of moderate alcohol consumption on subsequent food intake. In addition, we explored the role of oral and gut sensory pathways in alcohol's effect on food reward by modified sham feeding (MSF) or consumption of a preload after alcohol intake.In a single-blind crossover design, 24 healthy men were randomly assigned to either consumption of vodka/orange juice (20 g alcohol) or orange juice only, followed by consumption of cake, MSF of cake or no cake. Food reward was evaluated by actual food intake measured by an ad libitum lunch 45 min after alcohol ingestion and by behavioural indices of wanting and liking of four food categories (high fat, low fat, sweet and savoury).Moderate alcohol consumption increased food intake during the ad libitum lunch by 11% (+338 kJ, P = 0.004). Alcohol specifically increased intake (+127 kJ, P foods. Moreover, moderate alcohol consumption increased implicit wanting for savoury (P = 0.013) and decreased implicit wanting for sweet (P = 0.017) before the meal. Explicit wanting of low-fat savoury foods only was higher after alcohol followed by no cake as compared to after alcohol followed by cake MSF (P = 0.009), but not as compared to alcohol followed by cake consumption (P = 0.082). Both cake MSF and cake consumption had no overall effect on behavioural indices of food reward.To conclude, moderate alcohol consumption increased subsequent food intake, specifically of high-fat savoury foods. This effect was related to the higher food reward experienced for savoury foods. The importance of oral and gut sensory signalling in alcohol's effect on food reward remains largely unclear.

    2017-04-01

    Avoidant/restrictive food intake disorder (ARFID) is an entirely new diagnosis in the DSM-5. ARFID replaces "feeding disorder of infancy or early childhood," which was a diagnosis in the DSM-IV restricted to children 6 years of age or younger; ARFID has no such age limitations and it is distinct from anorexia nervosa and bulimia nervosa in that there is no body image disturbance. ARFID involves a complex and heterogenous etiology, which is reviewed herein. What is known to date regarding the characteristics and medical and psychiatric comorbidities of this patient population are described and compared to other eating disorders. Evaluation and management strategies are also discussed. No data yet exist regarding ARFID׳s prognosis and prevention; however, recommendations to guide parents in establishing appropriate infant and child feeding practices are provided.

  1. Food intake monitoring: an acoustical approach to automated food intake activity detection and classification of consumed food

    International Nuclear Information System (INIS)

    Päßler, Sebastian; Fischer, Wolf-Joachim; Wolff, Matthias

    2012-01-01

    Obesity and nutrition-related diseases are currently growing challenges for medicine. A precise and timesaving method for food intake monitoring is needed. For this purpose, an approach based on the classification of sounds produced during food intake is presented. Sounds are recorded non-invasively by miniature microphones in the outer ear canal. A database of 51 participants eating seven types of food and consuming one drink has been developed for algorithm development and model training. The database is labeled manually using a protocol with introductions for annotation. The annotation procedure is evaluated using Cohen's kappa coefficient. The food intake activity is detected by the comparison of the signal energy of in-ear sounds to environmental sounds recorded by a reference microphone. Hidden Markov models are used for the recognition of single chew or swallowing events. Intake cycles are modeled as event sequences in finite-state grammars. Classification of consumed food is realized by a finite-state grammar decoder based on the Viterbi algorithm. We achieved a detection accuracy of 83% and a food classification accuracy of 79% on a test set of 10% of all records. Our approach faces the need of monitoring the time and occurrence of eating. With differentiation of consumed food, a first step toward the goal of meal weight estimation is taken. (paper)

  9. The neurobiology of food intake in an obesogenic environment.

    Science.gov (United States)

    Berthoud, Hans-Rudolf

    2012-11-01

    The objective of this non-systematic review of the literature is to highlight some of the neural systems and pathways that are affected by the various intake-promoting aspects of the modern food environment and explore potential modes of interaction between core systems such as hypothalamus and brainstem primarily receptive to internal signals of fuel availability and forebrain areas such as the cortex, amygdala and meso-corticolimbic dopamine system, primarily processing external signals. The modern lifestyle with its drastic changes in the way we eat and move puts pressure on the homoeostatic system responsible for the regulation of body weight, which has led to an increase in overweight and obesity. The power of food cues targeting susceptible emotions and cognitive brain functions, particularly of children and adolescents, is increasingly exploited by modern neuromarketing tools. Increased intake of energy-dense foods high in fat and sugar is not only adding more energy, but may also corrupt neural functions of brain systems involved in nutrient sensing as well as in hedonic, motivational and cognitive processing. It is concluded that only long-term prospective studies in human subjects and animal models with the capacity to demonstrate sustained over-eating and development of obesity are necessary to identify the critical environmental factors as well as the underlying neural systems involved. Insights from these studies and from modern neuromarketing research should be increasingly used to promote consumption of healthy foods.

    Because overconsumption of food contributes to ill health, understanding what affects how much people eat is of importance. The 'bogus' taste test is a measure widely used in eating behaviour research to identify factors that may have a causal effect on food intake. However, there has been no examination of the validity of the bogus taste test as a measure of food intake. We conducted a participant level analysis of 31 published laboratory studies that used the taste test to measure food intake. We assessed whether the taste test was sensitive to experimental manipulations hypothesized to increase or decrease food intake. We examined construct validity by testing whether participant sex, hunger and liking of taste test food were associated with the amount of food consumed in the taste test. In addition, we also examined whether BMI (body mass index), trait measures of dietary restraint and over-eating in response to palatable food cues were associated with food consumption. Results indicated that the taste test was sensitive to experimental manipulations hypothesized to increase or decrease food intake. Factors that were reliably associated with increased consumption during the taste test were being male, have a higher baseline hunger, liking of the taste test food and a greater tendency to overeat in response to palatable food cues, whereas trait dietary restraint and BMI were not. These results indicate that the bogus taste test is likely to be a valid measure of food intake and can be used to identify factors that have a causal effect on food intake.

    2010-04-01

    A double-blind randomized intervention study has previously shown that a significant relationship exists between the consumption of various mixes of seven target additives by children and the onset of hyperactive behaviour. The present study set out to ascertain the pattern of intake of two mixes (A and B) of these seven target additives in Irish children and teenagers using the Irish national food consumption databases for children (n = 594) and teenagers (n = 441) and the National Food Ingredient Database. The majority of additive-containing foods consumed by both the children and teenagers contained one of the target additives. No food consumed by either the children or teenagers contained all seven of the target food additives. For each additive intake, estimates for every individual were made assuming that the additive was present at the maximum legal permitted level in those foods identified as containing it. For both groups, mean intakes of the food additives among consumers only were far below the doses used in the previous study on hyperactivity. Intakes at the 97.5th percentile of all food colours fell below the doses used in Mix B, while intakes for four of the six food colours were also below the doses used in Mix A. However, in the case of the preservative sodium benzoate, it exceeded the previously used dose in both children and teenagers. No child or teenager achieved the overall intakes used in the study linking food additives with hyperactivity.

    High prevalence of obesity and non-communicable diseases is a global public health problem, in which the quality of food environments is thought to play an important role. Current scientific evidence is not consistent regarding the impact of food environments on diet. The relationship between local food environments and diet quality was assessed across 10 Australian suburbs, using Australian-based indices devised to measure the two parameters. Data of dietary habits from the participants was gathered using a short questionnaire. The suburbs' Food Environment Score (higher being healthier) was associated with higher consumption of fruit (χ² (40, 230) = 58.8, p = 0.04), and vegetables (χ² (40, 230) = 81.3, p = 0.03). The Food Environment Score identified a significant positive correlation with four of the diet scores: individual total diet score (r s = 0.30, p food score (r s = 0.15, p Food Environment Index, higher being unhealthier) showed a significant association with higher consumption of salty snacks (χ² (24, 230) = 43.9, p = 0.04). Food environments dominated by food outlets considered as 'healthier' were associated with healthier population food intakes, as indicated by a higher consumption of fruit, vegetables, and water, as well as a lower consumption of junk food, salty snacks, and sugary drinks. This association suggests that healthier diet quality is associated with healthier food environments in regional Australia.

    Objective: To obtain concentrations of elements in Chinese current foods and their dietary intakes by adult man in order to provide a basis on intake parameters of Chinese Reference Man and make related hygienic evaluation. Methods: With mixed food sample method of total diet study, determination of element concentrations in constituent foods of diets for 4 areas with different diet types was carried out by using NAA, ICP-MS, ICP-AES, AAS and necessary QA measures, and estimation of their daily intakes and hygienic evaluation were also made. Results: The concentrations of 42 elements in 12 categories of foods, their intakes and hygienic evaluation for adult man were obtained. Conclusion: The data on element concentrations in Chinese foods and their dietary intakes were updated and widened. These data provided a new basis for developing the parameters of Chinese Reference Man and revealed some current hygienic problems. For example, from viewpoint of nutrition hygiene the Ca, Zn, and Cu intakes for Chinese Reference Man are insufficient, and from consideration of food hygiene the intakes of Pb,Cd and Na are excessive.. Especially, and Cd average daily intakes of Pb, Cd and Hg have been increased during recent years, those of Pb exceed their ADIs, which should be paid attention to

  15. Analysis of Total Food Intake and Composition of Individual's ...

    Science.gov (United States)

    EPA released the final report, Analysis of Total Food Intake and Composition of Individual’s Diet Based on USDA’s 1994-1996, 98 Continuing Survey of Food Intakes by Individuals (CSFII). The consumption of food by the general population is a significant route of potential exposure to hazardous substances that are present in the environment. For this reason, a thorough analysis of the dietary habits of the American public would aid in the identification of potential exposure pathways. To that end, the EPA developed per capita food intake rates for various food items and food categories using databases developed by the United States Department of Agriculture (USDA). These intake rates were incorporated into EPA's 1997 Exposure Factors Handbook. Since that time, EPA has recommended that the food intake study be updated and expanded to include a more comprehensive analysis of food intake. That analysis is presented in this document. The purpose of this study is to characterize the consumption of food by the people of the United States.

    Full Text Available Phosphorus intake in Europe is far above recommendations. We present baseline data from three human intervention studies between 2006 and 2014 regarding intake and excretion of phosphorus and calcium. All subjects documented their nutritional habits in weighed dietary records. Fasting blood samples were drawn, and feces and urine were quantitatively collected. Dietary phosphorus intake was estimated based on weighed dietary records and urine phosphorus excretions. Food sources were identified by allocation to defined food product groups. Average phosphorus consumption was 1338 mg/day and did not change from 2006 to 2014, while calcium intake decreased during this period (1150 to 895 mg/day. The main sources for phosphorus intake were bread/cereal products, milk/milk products and meat/meat products/sausage products and the main sources of calcium intake included milk/milk products/cheese, bread/cereal products and beverages. There was no difference between estimated phosphorus intake from the weighed dietary records and urine phosphorus excretion. In conclusion, we demonstrated constant phosphorus intakes far above the recommendations and decreasing calcium intakes below the recommendations in three German collectives from 2006 to 2014. Furthermore, we could show in case of usual intakes that an estimated phosphorus intake from urine phosphorus excretion is similar to the calculated intake from weighed dietary records.

  17. Food intake regulation in children. Fat and sugar substitutes and intake.

    Science.gov (United States)

    Birch, L L; Fisher, J O

    1997-05-23

    A series of experiments exploring children's responsiveness to manipulations of energy density and macronutrient content of foods have been reviewed to assess the nutritional impact of macronutrient substitutes on children's intake. In these experiments, the focus is on the extent to which the energy content of foods was a salient factor influencing children's food intake, and macronutrient substitutes were used as tools to investigate this issue. Therefore, although several different macronutrient substitutes have been used in this research, we do not have a parametric set of experiments systematically assessing the impact of a variety of macronutrient substitutes. Given this, what can we conclude from the existing data? When the energy density and macronutrient content of foods is altered through the use of macronutrient substitutes that reduce the energy content of foods, children tend to adjust for the missing energy, although this adjustment may be partial and incomplete. This suggests the possibility that when macronutrient substitutes are used to reduce the energy content of foods, children's energy intake may be reduced. This adjustment, however, will most likely be less than a "calorie for calorie" reduction. In addition, even among young children, there are individual differences in the extent to which children adjust their intake in response to macronutrient and energy manipulations. The data are more extensive and particularly clear for cases in which CHO manipulations are used to alter energy density, but there is evidence for adjustments in energy intake in response to alterations of the fat content of the diet. The compensation for energy is not macronutrient specific; that is, when the fat content of food is reduced to reduce energy density of foods, children do not selectively consume fat in subsequent meals. This means that manipulations of macronutrient content of foods that reduce foods' energy content may not result in alterations of energy

    Left ventricular wall stress has been investigated in a variety of populations, but the effect of food intake has not been evaluated. We assessed whether left ventricular wall stress is affected by food intake in healthy subjects. Twenty-three healthy subjects aged 25.6 ± 4.5 years were investigated. Meridional end-systolic wall stress (ESS) and circumferential end-systolic wall stress (cESS) were measured before, 30 minutes after, and 110 minutes after a standardised meal. Both ESS and cESS decreased significantly (P stress is affected by food intake in healthy subjects.

  1. Food intake rate and delivery strategy in aquaculture

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    In aquaculture, it is important to estimate in advance how much food cultured animals would take. The rate of food consumption by cultured animals to available food amount is defined as the food intake rate (FIR) in this paper. To some extents, FIR reflects the quality of food, the health of cultured animals and the delivery efficiency. In practice, it is difficult to estimate in advance the accurate quantity of food that cultured animal needs. Usually, food is provided more than the need by animals, causing excess food that may pollute water and environment. Our experiments in past years show that FIR at 80% is recommended.

Data on food and nutrient intakes from 3-day diet records over 10 years were used to estimate mean intakes and percent meeting Dietary Guidelines (DGA recommendations for food intakes and Institute of Medicine’s recommendations for vitamins and minerals. More than 90% of girls failed to consume the recommended amounts of fruit, vegetables and dairy; 75% consumed less than the recommended amounts in the “meat” group. The vast majority of girls of all ages had inadequate intakes of calcium, magnesium, potassium, and vitamins D and E. In contrast, they consumed >750 kcal/day (~40% of total energy from the DGA category of solid fat and added sugars, about five times the recommended maximum intakes. This study shows the importance of consuming a variety of foods in all five food groups, including those that are more energy dense such as dairy and meats, in order to meet a broad range of nutrient guidelines. Diet patterns that combined intakes across food groups led to greater improvements in overall nutritional adequacy.

    The aim of the present study performed in a Romanian population was to identify the food which can be either associated with or protect against colorectal carcinoma. Correlation and regression analysis were used to examine the association between dietary intake and the rate of incidence for colon, rectum and anus cancers, in study groups from 7 regions of Romania. A strong and positive association was observed for colonic cancer and the intake of coffee, tea and cocoa (r = 0.77, p = 0.042) whereas statistical significance of borderline value was found for margarine (r = 0.73, p = 0.06) and sweets (r = 0.74, p = 0.066) intake. A potential protective effect can be attributed to wine consumption ( r = -0.75, p = 0.03). The malignancies of the rectum and anus showed both a strong positive correlation with the intake of red meat ( r = 0.76, p = 0.048), sausages ( r = 0.87, p = 0.012), margarine (r = 0.97, p = 0.0004), butter ( r = 0.76, p = 0.049), sweets ( r = 0.93, p = 0.003), beverages (r = 0.97, p = 0.0003), coffee, tea, cocoa ( r = 0.94, p = 0.002). Negative correlations were reported for the recto-anal cancer and the consumption of: fish (r = -0.8, p = 0.032), cheese (r = -0.9, p = 0.006), wine (r = -0.85, p = 0.015). The need for reducing the dietary intake of margarine, red meat, sausages and sweets while the beneficial effects of wine consumption have been also confirmed.

METHODS: The sample consisted of 1,330 students aged 11 to 17 years attending the public schools of Salvador, Bahia, Brazil. The subjects' food intake data were collected by a semiquantitative Food Frequency Questionnaire comprising 97 food items. All information was collected during a single interview. The exposure variables were gender, age, and socioeconomic class, and the outcome variables were categorized food consumption pattern in "mixed pattern", "traditional pattern", and "healthy pattern". The data were treated by simple and multiple linear regression analyses and the dietary patterns determined by factor analysis. RESULTS: Most participants were female (56.9% and over 13 years old (79.2%. The "mixed pattern" was positively associated with females (β=0.181, p0.0001 and classes D, C, and B (β=-0.125, p<0.023. CONCLUSION: Three dietary patterns were identified among the adolescents, namely mixed, traditional, and healthy. Gender and socioeconomic class were associated with dietary patterns. Male teenagers and those in the lower socioeconomic classes had a healthier dietary pattern than their peers of higher socioeconomic classes and females.

    Expectations about a food's satiating capacity predict self-selected portion size, food intake and food choice. However, two individuals might have a similar expectation, but one might be extremely confident while the other might be guessing. It is unclear whether confidence about an expectation affects adjustments in energy intake at a subsequent meal. In a randomized cross-over design, 24 subjects participated in three separate breakfast sessions, and were served a low-energy-dense preload (53 kcal/100 g), a high-energy-dense preload (94 kcal/100 g), or no preload. Subjects received ambiguous information about the preload's satiating capacity and rated how confident they were about their expected satiation before consuming the preload in its entirety. They were served an ad libitum test meal 30 min later. Confidence ratings were negatively associated with energy compensation after consuming the high-energy-dense preload (r = -0.61; p = 0.001). The same relationship was evident after consuming the low-energy-dense preload, but only after controlling for dietary restraint, hunger prior to, and liking of the test meal (p = 0.03). Our results suggest that confidence modifies short-term controls of food intake by affecting energy compensation. These results merit consideration because imprecise caloric compensation has been identified as a potential risk factor for a positive energy balance and weight gain.

    Limited empirical evidence exists for how economic conditions affect micronutrient nutrition. We hypothesized that increasing poverty and rising food prices would reduce consumption of high-quality "luxury" foods, leading to an increased probability of inadequacy for several nutrients. The 2006 Guatemala National Living Conditions Survey was analyzed. First, energy and nutrient intakes and adequacy levels were calculated. Second, the income-nutrient relationships were investigated by assessing disparities in intakes, determining income-nutrient elasticities, and modeling nutrient intakes by reductions in income. Third, the food price-nutrient relationships were explored through determination of price-nutrient elasticities and modeling 2 price scenarios: an increase in food prices similar in magnitude to the food price crisis of 2007-2008 and a standardized 10% increase across all food groups. Disparities in nutrient intakes were greatest for vitamin B-12 (0.38 concentration index) and vitamin A (0.30 concentration index); these nutrients were highly and positively correlated with income (r = 0.22-0.54; P < 0.05). Although the baseline probability of inadequacy was highest for vitamin B-12 (83%), zinc showed the greatest increase in probability of inadequacy as income was reduced, followed by folate and vitamin A. With rising food prices, zinc intake was most acutely affected under both scenarios (P < 0.05) and folate intake in the poorest quintile (+7 percentage points) under the 10% scenario. Price-nutrient elasticities were highest for vitamin B-12 and the meat, poultry, and fish group (-0.503) and for folate and the legumes group (-0.343). The economic factors of food prices and income differentially influenced micronutrient intakes in Guatemala, notably zinc and folate intakes.

    The increase in obesity prevalence highlights the need for a more comprehensive understanding of the neural systems controlling food intake; one that extends beyond food intake driven by metabolic need and considers that driven by higher-order cognitive factors. The hippocampus, a brain structure involved in learning and memory function, has recently been linked with food intake control. Here we examine whether administration of the adiposity hormone leptin to the dorsal and ventral sub-regions of the hippocampus influences food intake and memory for food. Leptin (0.1 μg) delivered bilaterally to the ventral hippocampus suppressed food intake and body weight measured 24 h after administration; a higher dose (0.4 μg) was needed to suppress intake following dorsal hippocampal delivery. Leptin administration to the ventral but not dorsal hippocampus blocked the expression of a conditioned place preference for food and increased the latency to run for food in an operant runway paradigm. Additionally, ventral but not dorsal hippocampal leptin delivery suppressed memory consolidation for the spatial location of food, whereas hippocampal leptin delivery had no effect on memory consolidation in a non-spatial appetitive response paradigm. Collectively these findings indicate that ventral hippocampal leptin signaling contributes to the inhibition of food-related memories elicited by contextual stimuli. To conclude, the results support a role for hippocampal leptin signaling in the control of food intake and food-related memory processing.

  17. Hunger, taste, and normative cues in predictions about food intake.

    Normative eating cues (portion size, social factors) have a powerful impact on people's food intake, but people often fail to acknowledge the influence of these cues, instead explaining their food intake in terms of internal (hunger) or sensory (taste) cues. This study examined whether the same biases apply when making predictions about how much food a person would eat. Participants (n = 364) read a series of vignettes describing an eating scenario and predicted how much food the target person would eat in each situation. Some scenarios consisted of a single eating cue (hunger, taste, or a normative cue) that would be expected to increase intake (e.g., high hunger) or decrease intake (e.g., a companion who eats very little). Other scenarios combined two cues that were in conflict with one another (e.g., high hunger + a companion who eats very little). In the cue-conflict scenarios involving an inhibitory internal/sensory cue (e.g., low hunger) with an augmenting normative cue (e.g., a companion who eats a lot), participants predicted a low level of food intake, suggesting a bias toward the internal/sensory cue. For scenarios involving an augmenting internal/sensory cue (e.g., high hunger) and an inhibitory normative cue (e.g., a companion who eats very little), participants predicted an intermediate level of food intake, suggesting that they were influenced by both the internal/sensory and normative cue. Overall, predictions about food intake tend to reflect a general bias toward internal/sensory cues, but also include normative cues when those cues are inhibitory. If people are systematically biased toward internal, sensory, and inhibitory cues, then they may underestimate how much food they or other people will eat in many situations, particularly when normative cues promoting eating are present.

    This research examines the extent to which people accurately report some of the external influences on their food intake. In two studies, specific factors (the presence and behavior of others) were manipulated in order to influence the amount of food that individuals consumed. The main outcomes of interest were participants' spontaneously generated explanations for their food intake (Study 1; n = 122), and their ratings of the importance of several potential determinants of food intake (Study 2; n = 75). In Study 1, there was high concordance between the amounts eaten by members of a dyad, but very few participants indicated that they were influenced by their partner's behavior; they instead identified hunger and taste as the primary determinants of intake. Study 2 showed that participants' intake was strongly influenced by the behavior of others, but people rated taste and hunger as much more important influences on their intake. If external environmental factors influence people's food intake without their awareness or acknowledgment, then maintaining a healthy diet can be a challenge, with long-term consequences for health and well-being.

    Food rejection behaviors such as picky eating are of concern for many parents and attempts to increase healthy food intake can cause distress at mealtimes. An important limitation in most of the picky eating studies is that they cover few characteristics of picky eating behaviors and use limited measures of food intake. The objective of this study was to explore the associations between picky eating, child eating characteristics, and food intake among toddlers 12-47.9 months old (n = 2371) using data from the 2008 Feeding Infants and Toddlers Study (FITS). Logistic regression was used to examine associations between demographic and feeding characteristics and picky eater status. Differences in food group intake between picky and non-picky eaters were analyzed. Picky eaters were more likely to be neophobic, texture resistant, and to eat only favorite foods, In addition, the parents of picky eaters tend to offer new food a greater number of times than those of non-picky eaters before deciding that the child does not like it. Picky eaters showed significant lower intakes of eggs, burritos/tacos/enchiladas/nachos and sandwiches than non-picky eaters. Picky eaters consumed fewer vegetables from the "other vegetables" category and less raw vegetables than non-picky eaters. Neophobia, eating only favorite foods and difficulties with texture are all important characteristics of picky eaters which need to be integrated in studies measuring picky eating behaviors. Food intake of picky eaters differs only slightly from non-picky eaters. Because picky eating is a major parental concern, feeding strategies and advice related to the relevant characteristics of picky eating behavior need to be developed and assessed for their effectiveness.

    2013-09-01

    Research on emotions as a trigger for food intake has mainly been focused on the role of negative emotions. In the present studies the role of positive emotions as a trigger for food intake is investigated in a sample of healthy participants with a normal weight. Two laboratory studies were conducted in which positive emotions or no emotions were induced (Study 1) or in addition negative emotions were induced (Study 2) after which unhealthy food intake was assessed by bogus taste tests. In Study 3, food intake was assessed by registering snack intake in a 7-day diary study together with the emotions accompanying each snacking episode to provide a more ecologically valid test of our hypothesis. Studies 1 and 2 showed that positive emotions, compared to the control conditions, evoked more caloric intake. Dietary restraint did not moderate this effect. Study 2 additionally showed that positive emotions evoked caloric intake to the same extent as negative emotions. Study 3 showed that snack intake in daily life was reported to result from positive emotions more frequently than from negative emotions. Positive emotions serve as an important but under-investigated trigger for unhealthy food intake that deserves further scrutiny. Future research should further investigate whether food intake results from emotional arousal in general, or from emotional valence in particular. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Caenorhabditis elegans has emerged as a powerful model to study the genetics of feeding, food-related behaviors, and metabolism. Despite the many advantages of C. elegans as a model organism, direct measurement of its bacterial food intake remains challenging. Here, we describe two complementary methods that measure the food intake of C. elegans. The first method is a microtiter plate-based bacterial clearing assay that measures food intake by quantifying the change in the optical density of bacteria over time. The second method, termed pulse feeding, measures the absorption of food by tracking de novo protein synthesis using a novel metabolic pulse-labeling strategy. Using the bacterial clearance assay, we compare the bacterial food intake of various C. elegans strains and show that long-lived eat mutants eat substantially more than previous estimates. To demonstrate the applicability of the pulse-feeding assay, we compare the assimilation of food for two C. elegans strains in response to serotonin. We show that serotonin-increased feeding leads to increased protein synthesis in a SER-7-dependent manner, including proteins known to promote aging. Protein content in the food has recently emerged as critical factor in determining how food composition affects aging and health. The pulse-feeding assay, by measuring de novo protein synthesis, represents an ideal method to unequivocally establish how the composition of food dictates protein synthesis. In combination, these two assays provide new and powerful tools for C. elegans research to investigate feeding and how food intake affects the proteome and thus the physiology and health of an organism.

    Preterm delivery represents a substantial problem in perinatal medicine worldwide. Current knowledge on potential influences of probiotics in food on pregnancy complications caused by microbes is limited. We hypothesized that intake of food with probiotics might reduce pregnancy complications caused by pathogenic microorganisms and, through this, reduce the risk of spontaneous preterm delivery. This study was performed in the Norwegian Mother and Child Cohort on the basis of answers to a food-frequency questionnaire. We studied intake of milk-based products containing probiotic lactobacilli and spontaneous preterm delivery by using a prospective cohort study design (n = 950 cases and 17,938 controls) for the pregnancy outcome of spontaneous preterm delivery (delivery were associated with any intake of milk-based probiotic products in an adjusted model [odds ratio (OR): 0.857; 95% CI: 0.741, 0.992]. By categorizing intake into none, low, and high intakes of the milk-based probiotic products, a significant association was observed for high intake (OR: 0.820; 95% CI: 0.681, 0.986). Women who reported habitual intake of probiotic dairy products had a reduced risk of spontaneous preterm delivery.

    Examine intakes of energy and macronutrients, and identify their food sources, in Thai preschool children. Data from the Thai National Health Examination Survey (NHES) IV were used. Mothers/caregivers were interviewed regarding their children's 24-hour-dietary intake. Dietary data were analyzed for energy and macronutrients, and their food sources were investigated. Due to skewed data, Mann-Whitney U test was used to compare energy and macronutrient intake between sexes and age groups. Among 256 preschool children, more than 90% had protein intakes higher than the recommended level. Only 12.7 to 29.0% met the recommended intake for energy. Amounts of carbohydrate and fat consumed varied from below to above the Dietary Reference Intake (DRI) recommendation. Intakes of carbohydrate in boys and fat in girls were statistically different between age groups (p energy came from dairy products, grains and starchy products. The major carbohydrate contributors were grains and starchy products. Dairy products were the main source of protein. Important food sources of fat were dairy products for one- to three-year-old children and fat and oils for four- to five-year-old children. Thai preschool children have inappropriate intakes of energy and macronutrients. Dairy products and grains and/or starchy products were the main sources of energy, carbohydrate, and protein. Dietary fat sources varied by age group.

    To compare the consumption patterns and diet quality of foods and beverages obtained from various sources by food security status. Cross-sectional analysis of 2011-2012 National Health and Nutrition Examination Survey data. A total of 4,789 adults (aged >19 years) with dietary intake and food security data. The contribution of foods and beverages to energy, nutrients, and diet quality by locations where food was obtained was compared across food security status. Descriptive analysis and logistic regression. Almost all US adults consumed food and beverages obtained from grocery stores, regardless of food security status (about 95%), which accounted for one half to two thirds of total macronutrient intakes. The diet quality of foods from grocery stores was better in highly food-secure adults. Convenience stores are used most by very low food-secure adults; those foods had the poorest diet quality profile. Dietary patterns of marginally food-secure adults more closely resembled sources and intakes of low and very low food-secure adults. Food-insecure adults use food sources differently, resulting in diet quality differences of foods and beverages obtained. Place-based interventions in the food environment may have differential effects by food security status. Copyright © 2017 Society for Nutrition Education and Behavior. Published by Elsevier Inc.

    Although high-intensity sweeteners are widely used to decrease the energy density of foods, little is known about how this affects hunger and food intake. We have studied the effects of consumption of commercially available foods sweetened with either sucrose or aspartame on subjective appetite ratings and food intake. When normal-weight non-dieting males and females were given large portions of either a high- or low-calorie pudding or jello and instructed to eat as much as they liked, they ate similar weights of the different caloric versions of each food. Despite the resulting difference in caloric intake (up to 206 kcal), subjects showed only a non-significant trend towards caloric compensation when presented with a variety of foods 2 h later. Total caloric intake (preload plus test meal) did not differ between conditions. Ratings of hunger, desire to eat, the amount subjects wanted to eat, and the pleasantness of the taste of the eaten food were similarly decreased and fullness similarly increased by consumption of the different caloric versions of the foods. Awareness of the caloric content of the foods did not influence intake or appetite in that both informed and uniformed subjects responded similarly in the tests. Thus reduced calorie foods suppressed ratings of hunger for several hours after consumption, but were not associated with a significant reduction in total energy intake.

    Rats received intragastric infusions of various specified chemical meals and were subsequently tested for a reduction in food intake. A second experiment, using a novel technique, tested for conditioned aversion to the meal infusions. The nonnutritive substances, kaolin clay and emulsified fluorocarbon, had no significant effect on food intake. Infusions of 1 M glucose and 1 M sorbitol reduced feeding behavior, but the 1 M sorbitol infusion also produced a conditioned aversion to flavored pellets paired with the sorbitol infusion, showing that the reduced feeding could have been caused by discomfort. Infusion of a high-fat meal consisting of emulsified triolein mixed with small amounts of sugar and protein or the rat's normal liquid diet, Nutrament, also reduced food intake, and both infusions failed to produce a conditioned aversion. The use of specified meals to understand the chemical basis of satiety requires a sensitive behavioral test to establish that the meal does not cause discomfort or other nonspecific effects.

    the use of a NMU analog as drug candidate for treatment of obesity and diabetes. Finally mRNA expression of NMU and NMUR1 in the gut and NMUR2 in the hypothalamus was investigated using a novel chromogen-based in situ hybridization (ISH) assay. Effects on food intake (6 and 18h post dosing) were addressed......Neuromedin U (NMU) is a gut-brain peptide, implicated in energy and glucose homeostasis via the peripherally expressed NMU receptor 1 (NMUR1) and the central NMUR2. We investigated the effects of a lipidated NMU analog on gastric emptying (GE), glucose homeostasis and food intake to evaluate...... in both mice and rats. The effects on GE and glycaemic control were assessed in mice, immediately after the first dose and after seven days of bidaily (BID) dosing. The lipidated NMU analog exerted robust reductions in GE and food intake in mice and improved glycaemic control when measured immediately...

    2012-06-01

    While larger containers have been found to increase food intake, it is unclear whether this effect is driven by container size, portion size, or their combination, as these variables are usually confounded. The study was advertised as examining the effects of snack food consumption on information processing and participants were served M&M's for free consumption in individual cubicles while watching a TV show. Participants were served (1) a medium portion of M&M's in a small (n=30) or (2) in a large container (n=29), or (3) a large portion in a large container (n=29). The larger container increased intake by 129% (199 kcal) despite holding portion size constant, while controlling for different confounding variables. This research suggests that larger containers stimulate food intake over and above their impact on portion size. Copyright © 2012 Elsevier Ltd. All rights reserved.

    The methylxanthine caffeine and ethyl alcohol are widely used and powerful psychotropic drugs, but their interactions are not well understood. Bombesin is a brain-gut neuropeptide which is thought to function as a neurochemical factor in the inhibitory control of voluntary alcohol ingestion. We assessed the effects of combinations of intraperitoneal doses of caffeine and bombesin on 5% w/v ethanol solution and food intake in deprived rats. Deprived male and female Wistar rats received access to 5% ethanol or Purina chow for 30 minutes after i.p. injections. In single doses, CAF and BBS significantly decreased both ethanol and food consumption, at 50 mg/kg and 10 {mu}g/kg, respectively. CAF and BBS combinations produced infra-additive, or less-than-expected inhibitory effects on ethanol intake, but simple additive inhibitory effects on food intake. This experimental evidence suggests a reciprocal blocking of effects of CAF and BBS on ethanol intake but not food intake. Caffeine, when interacting and bombesin, increases alcohol consumption beyond expected values. Caffeine could affect the operation of endogenous satisfy signals for alcohol consumption.

    The aims of this cross-sectional statistical study were to evaluate the association between obesity and dental caries and to assess the impact of food intake, oral hygiene and lifestyle on the incidence of dental caries in obese paediatric patients, analysed by Dual X-ray Absorptiometry (DXA). A sample of 96 healthy patients, aged between 6 and 11 years (mean age 8.58±1.43) was classified in relation to body composition assessment and McCarthy growth charts and cut- offs. Body composition analysis, to obtain body fat mass (FM) and body fat free mass (FFM) measurements, was determined by means of a DXA fan beam scanner. The subjects underwent dental examination to assess the dmft/DMFT, and completed a questionnaire on food intake, oral hygiene habits and lifestyle. The sample was subsequently subdivided into four groups: Group A (normal weight - caries-free), Group B (normal weight with caries), Group C (pre-obese/obese - caries-free), Group D (pre-obese/obese with caries). The statistical analysis was performed using SPSS software (version 16; SPSS Inc., Chicago IL, USA). Spearman's correlation was performed to evaluate the correlation between dmft/DMFT and FM%. The chi-square test was performed to assess the categorical variables, while the non-parametric Kruskal Wallis test and the Mann Whitney test were employed for the quantitive variables. Statististical significance was set at a P-value of 0.05. The preobese-obese children had higher indexes of dental caries than normal weight subjects, both for deciduous teeth (dmft 2.5 ± 0.54 vs 1.4 ± 0.38; p=0.030) and permanent teeth (DMFT 2.8 ± 0.24 vs 1.93 ± 1.79; p=0.039). The correlations between dmft/DMFT indexes and body composition parameters were analysed and a significant correlation between dmft/DMFT indexes and FM% was observed (p=0.031 for dmft, p=0.022 for DMFT). According to the data recorded, there was no statistically significant difference between Groups A, B, C and D in terms of food intake between

    The authors have previously shown, using a 99m-Tc scrambled egg meal, that pentose sugars (i.e. xylose and arabinose) markedly prolong gastric emptying. Others have reported that slowing of gastric emptying may decrease appetite and thus decrease food intake. In the present study, the authors utilized the effects of xylitol (an FDA-approved pentose sugar) on gastric emptying to study the correlation between gastric emptying and food intake. Initially, gastric emptying was measured in human volunteers utilizing a standardized 99m-Tc-scrambled egg meal washed with 50 cc tap water. Results demonstrated a significant reduction in food intake (892 +- 65 kcal with water vs 654 +- 26 kcal following the ingestion of 25 gm xylitol (p<0.05). We conclude that the effect of pentose sugars in prolonging gastric emptying directly influences food intake and contributes to early satiety. The data suggest a role of xylitol as an essentially non-caloric food additive potentially important in diet control

  19. Preference or fat? Revisiting opioid effects on food intake.

    2010-07-14

    It is well established that opioid signaling in the central nervous system constitutes a powerful stimulus for food intake. The role of opioids in determining food preference, however, is less well defined. Opioids have been proposed to promote intake of preferred foods, or, alternatively, to preferentially increase consumption of fat. In the present manuscript, I comprehensively review results from previous studies investigating this issue. Data from these studies suggests a mechanism for opioid action that may reconcile the previously proposed hypotheses: opioid effects on food intake do appear to be largely specific for fat consumption, but individual animals' sensitivity to this effect may be dependent on baseline food preferences. In addition, I highlight the possibility that the selectivity of endogenous opioid effects may importantly differ from that of exogenous agonists in the degree to which baseline preferences, rather than macronutrient intake, are altered.

    The concentrations of naturally occurring radioisotopes ( 232 Th, 228 Th, 230 Th, 228 Ra, 226 Ra, and 40 K) in typical Korean foods were evaluated. The daily intakes of these radioisotopes were calculated by comparing concentrations in typical Korean foods and the daily consumption rates of these foods. Daily intakes were as follows: 232 Th, 0.00-0.23; 228 Th, 0.00-2.04; 230 Th, 0.00-0.26; 228 Ra, 0.02-2.73; 226 Ra, 0.01-4.37 mBq/day; and 40 K, 0.01-5.71 Bq/day. The total daily intake of the naturally occurring radioisotopes measured in this study from food was 39.46 Bq/day. The total annual internal dose resulting from ingestion of radioisotopes in food was 109.83 μSv/y, and the radioisotope with the highest daily intake was 40 K. These values were same level compiled in other countries

  1. Understanding the Relationship Between Food Variety, Food Intake, and Energy Balance.

    In accordance with US dietary guidance, incorporating variety into the diet can align with energy balance, though greater food variety in some categories may make energy balance more challenging. Thus, experimental and epidemiologic evidence is summarized on the relationship between food variety, food and energy intake, and energy balance. Lab-based, experimental research consistently demonstrates that greater variety within foods or sensory characteristics of food increases food and energy intake within an eating occasion. Epidemiologic evidence is less consistent, potentially driven by differing methodologies, particularly in defining and measuring food variety. Moreover, the effect of variety on energy balance appears to be moderated by food energy density. Integrating insights from experimental and epidemiologic research are essential for strengthening food variety guidance including developing evidence-based definitions of food variety, understanding moderators of the relationship, and developing practical guidance interpretable to consumers.

    Soy and some of its constituents, such as isoflavones, have been shown to have cancer-inhibitory activities in experimental studies. Data from epidemiologic studies linking usual soy food intake with colorectal cancer are limited and inconsistent. The objective was to investigate whether soy food intake is associated with colorectal cancer risk. We prospectively examined 68,412 women aged 40-70 y and free of cancer and diabetes at enrollment. Usual soy food intake was assessed at baseline (1997-2000) and reassessed during the first follow-up (2000-2002) through in-person interviews with a validated food-frequency questionnaire. We excluded the first year of observation to minimize lifestyle changes related to preclinical disease. During a mean follow-up of 6.4 y, 321 incident colorectal cancer cases were identified. After adjustment for potential confounding factors, total soy food intake was inversely associated with colorectal cancer risk. Each 5-g/d increment in intake of soy foods as assessed by dry weight [equivalent to approximately 1 oz (28.35 g) tofu/d] was associated with an 8% reduction in risk (95% CI: 3%, 14%). Women in the highest tertile of intake had a multivariate relative risk of 0.67 (95% CI: 0.49, 0.90) compared with those in the lowest tertile (P for trend = 0.008). This inverse association was primarily confined to postmenopausal women. Similar results were also found for intakes of soy protein and isoflavones. This prospective study suggests that consumption of soy foods may reduce the risk of colorectal cancer in postmenopausal women.

    Epidemiological studies were inconsistent on the association between soy food intake and risk of gastric cancer (GC). This study aimed to determine the role of soy food intake in the development of GC.A systematic search was conducted in PubMed and Web of Science to identify all relevant studies. Study-specific relative risks (RRs) and 95% confidence intervals (CIs) were pooled using a random-effects model, and the dose-response relationship between soy food intake and GC risk was also assessed.Thirteen prospective studies were identified with a total of 517,106 participants and 5800 cases. Among 11 types of soy food, high intake of total soy food (the highest vs the lowest category: RR: 0.78, 95% CI: 0.62-0.98) and nonfermented soy food (RR: 0.63, 95% CI: 0.50-0.79) were inversely associated with GC risk, while high intake of miso soup was associated with the risk in male (RR: 1.17, 95% CI: 1.02-1.36). In dose-response meta-analysis, total soy food intake (0-150 g/day) showed no significant association with GC risk, while high intake of nonfermented soy food was inversely related, especially an intake of more than 100 g/day. In male, miso soup intake (1-5 cups/day) was significantly associated with GC risk.High intake of nonfermented soy food might reduce the risk of GC, while miso soup intake might increase the risk in male.

    This study investigated how the air content of a familiar snack food affected energy intake and whether varying the method of serving the snack modified intake. We tested two versions of an extruded snack (cheese puffs) that were equal in energy density (5.7 kcal/g), but differed in energy per volume (less-aerated snack: 1.00 kcal/ml; more-aerated snack: 0.45 kcal/ml). In a within-subjects design, 16 women and 12 men consumed the snacks ad libitum in the laboratory during four afternoon sessions. A standard volume (1250 ml) of each snack was served once in a bowl and once in an opaque bag. Results showed significant differences in intake of the two snacks by energy (p=0.0003) and volume (psnack than the less-aerated snack, although they consumed a 73% greater volume of the more-aerated snack (239+/-24 ml). These findings suggest that subjects responded to both the weight and volume of the snack. Despite differences in intake, hunger and fullness ratings did not differ across conditions. The serving method did not significantly affect intake. Results from this study indicate that incorporating air into food provides a strategy to reduce energy intake from energy-dense snacks.

    Background and aim The sensory attributes of food play a key role in the selection and termination of meals and their rewarding properties. The majority of our foods are either sweet or savoury tasting. In addition, within our food range, savoury-tasting foods contain in general higher levels of protein.

    Protein food intake appears to partially structure dietary patterns, as most current emergent diets (e.g., vegetarian and flexitarian) can be described according to their levels of specific protein sources. However, few data are available on dietary protein patterns in the general population and their association with nutrient adequacy. Based on protein food intake data concerning 1678 adults from a representative French national dietary survey, and non-negative-matrix factorization followed by cluster analysis, we were able to identify distinctive dietary protein patterns and compare their nutrient adequacy (using PANDiet probabilistic scoring). The findings revealed eight patterns that clearly discriminate protein intakes and were characterized by the intakes of one or more specific protein foods: 'Processed meat', 'Poultry', 'Pork', 'Traditional', 'Milk', 'Take-away', 'Beef' and 'Fish'. 'Fish eaters' and 'Milk drinkers' had the highest overall nutrient adequacy, whereas that of 'Pork' and 'Take-away eaters' was the lowest. Nutrient adequacy could often be accounted for by the characteristics of the food contributing to protein intake: 'Meat eaters' had high probability of adequacy for iron and zinc, for example. We concluded that protein patterns constitute strong elements in the background structure of the dietary intake and are associated with the nutrient profile that they convey.

  7. Quantitative food frequency questionnaire and assessment of dietary intake.

    1998-01-01

    India is a land of varied foods and food habits. This makes the task of collecting dietary and nutrient intake data difficult. Methods need to be devised to improve the accuracy in reporting intakes by various population subgroups. There is an urgent need to develop a questionnaire that is simple enough to be administered on a large sample and whose validity and reproducibility has been quantified. Regional differences in food habits and availability will have to be taken into account in the questionnaire design. Packaging of food items with definite portion sizes is not a common practice in Indian markets and labels on food products are neither very informative nor descriptive. Epidemiologists addressing the effects of diet have generally used questionnaires that inquire about the frequency of specified foods consumed and sometimes also attempt to quantify usual portion sizes. A number of investigators have conveyed, apparently independently, that the food frequency questionnaire (FFQ) as a method of dietary assessment is best suited for most epidemiological applications. A food frequency list can form the basis for nutrition education and allows the dietician and the patient to relate individual eating patterns to specific foods. Other advantages of the FFQ are that it is independent of the ability or inclination of an individual to maintain a diary and also provides immediate feedback to patients, physicians and counsellors.

    This paper describes the different pathways by which food is contaminated after a release of radionuclides into the environment. Equations to calculate the contamination level, as well as the most important parameters used in these equations, are included. Thereupon is explained how the radiation dose can be calculated from the intake of radioactivity. The principles which are used to derive criteria for the amounts of radioactivity which are allowed in food are described. (author)

  9. Meal Microstructure Characterization from Sensor-Based Food Intake Detection

    Full Text Available To avoid the pitfalls of self-reported dietary intake, wearable sensors can be used. Many food ingestion sensors offer the ability to automatically detect food intake using time resolutions that range from 23 ms to 8 min. There is no defined standard time resolution to accurately measure ingestive behavior or a meal microstructure. This paper aims to estimate the time resolution needed to accurately represent the microstructure of meals such as duration of eating episode, the duration of actual ingestion, and number of eating events. Twelve participants wore the automatic ingestion monitor (AIM and kept a standard diet diary to report their food intake in free-living conditions for 24 h. As a reference, participants were also asked to mark food intake with a push button sampled every 0.1 s. The duration of eating episodes, duration of ingestion, and number of eating events were computed from the food diary, AIM, and the push button resampled at different time resolutions (0.1–30s. ANOVA and multiple comparison tests showed that the duration of eating episodes estimated from the diary differed significantly from that estimated by the AIM and the push button (p-value <0.001. There were no significant differences in the number of eating events for push button resolutions of 0.1, 1, and 5 s, but there were significant differences in resolutions of 10–30s (p-value <0.05. The results suggest that the desired time resolution of sensor-based food intake detection should be ≤5 s to accurately detect meal microstructure. Furthermore, the AIM provides more accurate measurement of the eating episode duration than the diet diary.

    Cholecystokinin decreases food intake in animals and in man. This study investigated whether the structurally related ceruletide reduces food intake in healthy non-obese man. Twelve females and 12 males participated, after an over-night fast, in each of two experiments. During the basal 40 min, saline was infused IV. Thereafter, the infusion was, in random double blind fashion, either continued with saline or switched to 60 or 120 ng/kg b. wt/hr ceruletide. Butter was melted in a pan and scrambled eggs with ham were prepared in front of the subjects, who were instructed to eat, together with bread and mallow tea, as much as they wanted. With 120 ng/kg/hr ceruletide, the subjects ate significantly less (16.8 percent) than with saline (3725 kJ +/- 489 SEM and 4340 kJ +/- 536, respectively; p less than 0.025). They also reported less hunger (p less than 0.005) and activation (p less than 0.005) and activation (p less than 0.01), and had longer reaction times (p less than 0.01) and a weaker psychomotor performance (p less than 0.025). 60 ng/kg/hr ceruletide decreased food intake only slightly (6.6%; 3089 kJ +/- 253 and 3292 kJ +/- 300 respectively) and no significant changes in the above measures occurred. In conclusion, ceruletide reduces food intake in man, thus resembling the effects of cholecystokinin.

    We examined whether people's attributions for their eating behaviour differ according to whether they believe they have eaten more, less or about the same as they normally would. Participants were served a small or large portion of pasta for lunch. Afterwards, they were asked to compare how much they ate in the study to how much they normally eat for lunch, resulting in three intake-evaluation categories: 'ate less', 'ate about the same' or 'ate more'. How much participants ate; the extent to which they attributed their food intake to an internal cue (i.e. hunger) and an external cue (i.e. the amount of food served). Participants served a large portion ate more than those served a small portion, but the magnitude of the portion-size effect did not vary across intake-evaluation categories. Furthermore, although participants in all groups indicated that their hunger influenced how much they ate, only those in the 'ate more' group indicated that the amount of food available influenced how much they ate. People appear to be willing to explain their food intake in terms of an external cue only when they believe that they have eaten more than they normally would.

    Ghrelin is a 28-amino-acid hormone derived from the endoproteolytic processing of its prehormone proghrelin. Although ghrelin has been reported to regulate food intake and body weight, it is still unknown whether proghrelin exercises any biological function. Here we show that recombinant proghrelin alters food intake and energy metabolism in mice. After intraperitoneal administration of recombinant proghrelin (100 nmol/kg body wt), cumulative food intake was significantly increased at days 1, 2, and 3 (6 +/- 0.3, 13 +/- 0.5, and 20 +/- 0.8 g vs. 5 +/- 0.2, 10 +/- 0.2, and 16 +/- 0.3 g of the control mice receiving normal saline, respectively, n = 6, P light photo period in mice treated with proghrelin increased significantly relative to the control (2.1 +/- 0.04 vs. 1.3 +/- 0.2 g, n = 6, P dark photo period was observed between mice treated with proghrelin and vehicle (4.2 +/- 0.6 vs. 4.3 +/- 0.6 g, n = 6, P > 0.05). This is associated with a decrease in body weight (0.42 +/- 0.04 g) for mice treated with proghrelin, whereas control animals gained body weight (0.31 +/- 0.04 g). Mice treated with proghrelin demonstrate a significant decrease in respiratory quotient, indicating an increase in fat consumption. Recombinant proghrelin is functionally active with effects on food intake and energy metabolism.

    Fruit and vegetable intake has been found to reduce the risk of cardiovascular disease, certain types of cancer and diabetes mellitus. It is possible that antioxidants play a large part in this protective effect. However, which foods account for the variation in antioxidant intake in a population is not very clear. We used food frequency data from a population-based sample of women to identify the food items that contributed most to the variation in antioxidant intake in Norwegian diet. We used data from a study conducted among participants in the Norwegian Breast Cancer Screening Program (NBCSP), the national program which invites women aged 50-69 years to mammographic screening every 2 years. A subset of 6514 women who attended the screening in 2006/2007 completed a food frequency questionnaire (FFQ). Daily intake of energy, nutrients and antioxidant intake were estimated. We used multiple linear regression analysis to capture the variation in antioxidant intake. The mean (SD) antioxidant intake was 23.0 (8.5) mmol/day. Coffee consumption explained 54% of the variation in antioxidant intake, while fruits and vegetables explained 22%. The twenty food items that contributed most to the total variation in antioxidant intake explained 98% of the variation in intake. These included different types of coffee, tea, red wine, blueberries, walnuts, oranges, cinnamon and broccoli. In this study we identified a list of food items which capture the variation in antioxidant intake among these women. The major contributors to dietary total antioxidant intake were coffee, tea, red wine, blueberries, walnuts, oranges, cinnamon and broccoli. These items should be assessed in as much detail as possible in studies that wish to capture the variation in antioxidant intake.

    Full Text Available ABSTRACT Objective: Evaluate the use of the Nutrabem (São Paulo, Brasil mobile application as a tool for measurement of food intake among university students. Methods: Cross-sectional study of a random sample of 40 undergraduate students at the Universidade Federal de São Paulo, Campus Baixada Santista. Food intake data were estimated using the Nutrabem app and the 24-hour dietary recall. Intakes of energy, carbohydrates, proteins, lipids, calcium, iron, and vitamin C were calculated. The intake of food groups and diet quality were evaluated by the Diet Quality Index associated with the Digital Food Guide. The agreement between the methods was assessed using the Pearson's correlation coefficient and the Student' t-test. Results: Strong correlations were observed between energy (0.77, carbohydrates (0.82 and protein (0.83. The groups: poultry, fish, and eggs; beef and pork; refined grains and breads; and fruits and legumes showed strong correlations (between 0.76 and 0.85. There were moderate correlations (0.59 and 0.71 between the groups sugars and sweets; whole grains, tubers and roots, milk and dairy products, animal fats, and the Diet Quality Index associated with the Digital Food Guide scores. Vegetables and leafy greens, nuts, and vegetable oils showed weak correlations (0.31 and 0.43. Homogeneity assessment revealed similarity between the results obtained by both methods (p>0.05 . Conclusion: The Nutrabem app can be used as a tool to assess dietary intake among university students since it produces results similar to those obtained by the 24-hour dietary recall method.

  4. Pavlovian influences over food and drug intake.

    2000-06-01

    Consuming food and taking drugs share several important characteristics. In particular, each causes changes in important physiological parameters that are constantly being monitored and regulated by the brain. As examples, blood glucose increases after meals; and body temperature decreases after ethanol is taken. Such changes elicit neurally-mediated homeostatic responses that serve to reduce the magnitude and duration of the perturbation. It is argued that when an individual can accurately anticipate pending meals or drugs, it can make appropriate responses to minimize or totally neutralize the meal/drug-elicited perturbations. This phenomenon, which is the basis for meal and drug tolerance, relies upon Pavlovian conditioning. Literature is reviewed which documents the role of conditioning processes in the development of tolerance. The argument is made that conditioned responses enable individuals to derive necessary or desirable aspects of food and drugs while minimizing some of their negative effects. In a final section, drug tolerance is discussed as a natural consequence of evolution-derived, meal-related learning processes, with associated negative consequences.

    Based on evidence that the color red elicits avoidance motivation across contexts (Mehta & Zhu, 2009), two studies investigated the effect of the color red on snack food and soft drink consumption. In line with our hypothesis, participants drank less from a red labeled cup than from a blue labeled cup (Study 1), and ate less snack food from a red plate than from a blue or white plate (Study 2). The results suggest that red functions as a subtle stop signal that works outside of focused awareness and thereby reduces incidental food and drink intake. Copyright © 2012 Elsevier Ltd.

    The reproducibility of three questions, related to fullness, satiety and desire to eat, rated on an unmarked triangle was verified. In four sessions 12 volunteers ate pasta with tomato sauce (520 kcal) and were asked to rate the sensations felt. There was no difference in rating scores of the replications so the proposed questionnaire provides a stable measure of sensations related to satiety. Subsequently three satiety conditions were studied. Two foods, one rich in carbohydrate, pasta (baked macaroni) and the other in protein, polpette (meatballs), were used as loads at two calorie levels and as preload before an "ad libitum" meal. All the three questions proved useful in discriminating between the different satiety conditions. The food intake underlines the specificity of satiety: subjects, after eating a preload which previously had satiated them, ate other foods in different amounts depending on the kind of preload eaten. Food intake was significantly higher after the pasta preload, furthermore "fullness" and "satiety" ratings were significantly highest after the meatball preload, suggesting that in our experimental conditions, meatballs were more satiating than pasta. In conclusion, this study highlights the validity of using several quite different questions to study hunger and satiety, together with the actual food intake.

  7. Obesity, food intake and exercise: Relationship with ghrelin

    2015-09-01

    Full Text Available Obesity, a disorder of body composition, is defined by a relative or absolute excess of body fat. In general adult population, obesity has been associated with a diverse array of adverse health outcomes, including major causes of death such as cancer, diabetes, cardiovascular disease, as well as functional impairment from problems such as osteoarthritis and sleep apnea. Ghrelin is a newly discovered peptide hormone which plays an important role in obesity. It is a powerful, endogenous orexigenic peptide and has a crucial function in appetite regulation, as well as short – and long-term energy homeostasis. In the presence of increased obesity, decreased physical activity, and high food consumption, the relationship between exercise, appetite, food intake and ghrelin levels has important implications. In this review, we discuss the effect of acute and chronic exercise performance on appetite, food intake and ghrelin and their relationships.

    The objective of this study was to investigate if food intake (dairy, snacks, caloric beverages, bread, cheese, margarine/butter, potato/rice/pasta/grains, red meat, fish and fruit/berries/vegetables) is associated with gestational weight gain (GWG) in Swedish women. Four day food records from 95 pregnant Swedish women were collected in the last trimester. GWG was calculated as weighed body weight in the last trimester (median gestational week 36) minus self-reported pre-pregnancy body weight. Excessive GWG was defined according to the guidelines by the Institute of Medicine. Food groups tested for association with GWG were dairy (milk, yoghurt and sour milk), snacks (sweets, crisps, popcorn, ice cream and cookies, but not nuts and seeds), caloric beverages (soft drinks, juice, lemonade and non-alcoholic beer), bread, cheese, margarine/butter, potato/rice/pasta/grains, red meat, fish and fruit/berries/vegetables. Median (lower-upper quartiles) GWG was 12.1 kg (10.0-15.3). In total, 28 % had an excessive GWG. Excessive GWG was most common among pre-pregnancy overweight and obese women, where 69 % had an excessive GWG. Median daily intake of fruits and vegetables was 352 g (212-453), caloric beverages was 238 g (100-420) and snacks was 111 g (69-115). Multivariable linear regression analysis showed that intake of caloric beverages, snacks, fish, bread and dairy in the last trimester of pregnancy were positively related to GWG (R(2) = 0.32). Multivariable logistic regression analysis showed that intake of caloric beverages, snacks, fish, and bread was associated with higher odds ratios for excessive GWG. Intake of caloric beverages, snacks, fish and bread were positively related to excessive GWG. Thus, these results indicate that maternal dietary intake should be given higher attention in the antenatal care.

  10. Watching TV and food intake: the role of content.

    Full Text Available Obesity is a serious and growing health concern worldwide. Watching television (TV represents a condition during which many habitually eat, irrespective of hunger level. However, as of yet, little is known about how the content of television programs being watched differentially impacts concurrent eating behavior. In this study, eighteen normal-weight female students participated in three counter-balanced experimental conditions, including a 'Boring' TV condition (art lecture, an 'Engaging' TV condition (Swedish TV comedy series, and a no TV control condition during which participants read (a text on insects living in Sweden. Throughout each condition participants had access to both high-calorie (M&Ms and low-calorie (grapes snacks. We found that, relative to the Engaging TV condition, Boring TV encouraged excessive eating (+52% g, P = 0.009. Additionally, the Engaging TV condition actually resulted in significantly less concurrent intake relative to the control 'Text' condition (-35% g, P = 0.05. This intake was driven almost entirely by the healthy snack, grapes; however, this interaction did not reach significance (P = 0.07. Finally, there was a significant correlation between how bored participants were across all conditions, and their concurrent food intake (beta = 0.317, P = 0.02. Intake as measured by kcals was similarly patterned but did not reach significance. These results suggest that, for women, different TV programs elicit different levels of concurrent food intake, and that the degree to which a program is engaging (or alternately, boring is related to that intake. Additionally, they suggest that emotional content (e.g. boring vs. engaging may be more associated than modality (e.g. TV vs. text with concurrent intake.

    During the last years, three promising techniques for the identification of irradiated food were developed: - Studies of luminescence, mainly thermoluminescence measurements, of food containing mineral impurities like spices, dried vegetables: and fresh fuit and vegetables. This technique can probably be applied also to food with crystalline components like shells or bones. - Gaschromatographic/mass-spectrometric investigation of radiation-induced lipid changes. - Electron-spin-resonance measurements of dried products or of products containing dry components like bones, fish bones, shells or seeds. The thermoluminescence technique has been routinely applied for more than one year by several German Food Inspection Laboratories. The results suggest that there are scarcely any irradiated spices and dried vegetables in the German market. Gaschromatography/mass spectrometry of lipid components and electron-spin-resonance spectroscopy will be established in routine food inspections in Germany in the next two years. Further possibilities to identify irradiated food are the analysis of specific changes in amino acids, DNA and carbohydrates. Radiation-induced viscosity changes, and changes in electric properties (impedance) may be helpful in identifiying at least some irradiated products. Also microbiological and biological techniques as e.g. microbial flora shift or embryo development tests in citrus fruit have been considered. All activities concerning the development of identification techniques are now coordinated by the European Communities and by IAEA. (orig.) [de

    Overeating is believed to result when the appetitive motivation to consume palatable food exceeds an individual's capacity for inhibitory control of eating. This hypothesis was supported in recent studies involving predominantly normal weight women, but has not been tested in obese populations. The current study tested the interaction between food reward sensitivity and inhibitory control in predicting palatable food intake among energy-replete overweight and obese women (N = 62). Sensitivity to palatable food reward was measured with the Power of Food Scale. Inhibitory control was assessed with a computerized choice task that captures the tendency to discount large delayed rewards relative to smaller immediate rewards. Participants completed an eating in the absence of hunger protocol in which homeostatic energy needs were eliminated with a bland preload of plain oatmeal, followed by a bogus laboratory taste test of palatable and bland snacks. The interaction between food reward sensitivity and inhibitory control was a significant predictor of palatable food intake in regression analyses controlling for BMI and the amount of preload consumed. Probing this interaction indicated that higher food reward sensitivity predicted greater palatable food intake at low levels of inhibitory control, but was not associated with intake at high levels of inhibitory control. As expected, no associations were found in a similar regression analysis predicting intake of bland foods. Findings support a neurobehavioral model of eating behavior in which sensitivity to palatable food reward drives overeating only when accompanied by insufficient inhibitory control. Strengthening inhibitory control could enhance weight management programs.

    A country-specific food composition databases is useful for assessing nutrient intake reliably in national nutrition surveys, research studies and clinical practice. The New Zealand Food Composition Database (NZFCDB) programme seeks to maintain relevant and up-to-date food records that reflect the composition of foods commonly consumed in New Zealand following Food Agricultural Organisation of the United Nations/International Network of Food Data Systems (FAO/INFOODS) guidelines. Food composition data (FCD) of up to 87 core components for approximately 600 foods have been added to NZFCDB since 2010. These foods include those identified as providing key nutrients in a 2008/09 New Zealand Adult Nutrition Survey. Nutrient data obtained by analysis of composite samples or are calculated from analytical data. Currently >2500 foods in 22 food groups are freely available in various NZFCDB output products on the website: www.foodcomposition.co.nz. NZFCDB is the main source of FCD for estimating nutrient intake in New Zealand nutrition surveys. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Cancer therapy causes side effects that interfere with oral intake. Frequently, patients undergoing such therapy suffer from anorexia, nausea, vomiting, food aversions, dysgeusia, and xerostomia, all which adversely affect oral intake. Adequate nutrition intake is an important part of therapy for the cancer patient, especially when that patient is a child. Children who are well nourished are better able to withstand infection and tolerate therapy. Parents and staff at our hospital have worked diligently to improve patient's oral intake with limited success. Hence, a multidisciplinary team was organized to develop a new approach to food services that would improve patients' oral intake. The team initiated patient "room service," and patients were allowed to call the kitchen when they were ready to eat. The system works much like room service in a hotel. After the introduction of room service, patients' caloric intake improved significantly (P = .008), and protein intake increased by 18%. Patient satisfaction with hospital food service also improved; excellent ratings increased by as much as 35%. We conclude that room service is a viable alternative to traditional food services in the pediatric oncology setting and may be useful in other patient populations, such as maternity and general pediatrics.

    The question of how to promote healthy eating habits in children is relevant because most children do not meet the recommended vegetable intake. Involving children in food preparation could be an opportunity to develop healthy eating behaviors and to increase vegetable consumption. The purpose of this study was to examine the effect of children's involvement in meal preparation on their food and vegetable intake. A between-subject experiment was conducted with 47 children aged 6 to 10 years. In condition 1 (n = 25), children prepared a lunch meal (pasta, breaded chicken, cauliflower, and salad) with the assistance of a parent. In condition 2 (n = 22), the meal was prepared by the parent alone. Independent samples t-tests were conducted to compare intake in the "child cooks" and "parent cooks" conditions. Children in the child cooks condition ate significantly more salad 41.7 g (76.1%), more chicken 21.8 g (27.0%), and more calories 84.6 kcal (24.4%) than children in the parent cooks condition. Between before cooking and directly after cooking the meal, children in the child cooks condition reported significantly increased feelings of valence (feeling positive) and dominance (feeling in control). This study confirms that involving children in meal preparation can increase vegetable intake. Because of the potential effect on energy intake, parents need to be made aware of appropriate portion sizes for their children. Taking this into account, encouraging parents to involve their children in the preparation of healthy and balanced meals could be a valuable intervention strategy to improve the diets and vegetable intake of children.

    High salt intake increases blood pressure and thereby the risk of chronic diseases. Food reformulation (or food product improvement) may lower the dietary intake of salt. This study describes the changes in salt contents of foods in the Dutch market over a five-year period (2011-2016) and differences in estimated salt intake over a 10-year period (2006-2015). To assess the salt contents of foods; we obtained recent data from chemical analyses and from food labels. Salt content of these foods in 2016 was compared to salt contents in the 2011 version Dutch Food Composition Database (NEVO, version 2011), and statistically tested with General Linear Models. To estimate the daily dietary salt intake in 2006, 2010, and 2015, men and women aged 19 to 70 years were recruited through random population sampling in Doetinchem, a small town located in a rural area in the eastern part of the Netherlands. The characteristics of the study population were in 2006: n = 317, mean age 49 years, 43% men, in 2010: n = 342, mean age 46 years, 45% men, and in 2015: n = 289, mean age 46 years, 47% men. Sodium and potassium excretion was measured in a single 24-h urine sample. All estimates were converted to a common metric: salt intake in grams per day by multiplication of sodium with a factor of 2.54. In 2016 compared to 2011, the salt content in certain types of bread was on average 19 percent lower and certain types of sauce, soup, canned vegetables and legumes, and crisps had a 12 to 26 percent lower salt content. Salt content in other types of foods had not changed significantly. Between 2006, 2010 and 2015 the estimated salt intake among adults in Doetinchem remained unchanged. In 2015, the median estimated salt intake was 9.7 g per day for men and 7.4 g per day for women. As in 2006 and 2010, the estimated salt intake in 2015 exceeded the recommended maximum intake of 6 g per day set by the Dutch Health Council.

    Over 20% of employees in Europe work in shifts. Shift work increases the risk for chronic diseases, but a healthy lifestyle may attenuate the adverse effect of shift work. The aim of this study was to explore food and nutrient intake differences between working time groups. The participants were 1478 employees (55% of men) of an airline divided into three working time groups: day work (n=608), shift work without in-flight work (n=541) and in-flight work (n=329). Measures included laboratory tests, physical measurements, a questionnaire, and food and nutrient intake estimations by a validated 16-item food intake questionnaire. Shift working men were less likely to consume vegetables (p<0.001) and fruits (p=0.049) daily than male day and in-flight workers. In women, energy intake from saturated fat was higher among shift workers compared with day workers (12.6 vs 12.2 E%, p=0.023). In older female participants, energy intake from fat and saturated fat was higher in the shift work and in-flight work groups than in the day work group (p<0.001). In this study, shift work and working environment were associated with dietary habits, and this association was not explained by other characteristics such as workers' educational level. Shift workers' increased risk for chronic diseases should be taken into account and lifestyle counselling including advice in nutrition should be incorporated in routine occupational healthcare of shift workers.

    Tritium incorporation into tissues and DNA of mice was studied after daily ingestion of tritiated food or tritiated water. The tritiated food used was a commercial preparation mixed with brine shrimp which had been reared in tritiated sea water. After ingestion of tritiated food or water for up to 22 d, the specific activity of tritium in tissues was measured as tissue-free-water tritium, tissue-bound tritium and DNA-bound tritium. In order to compare the tritium intake from food with that from water, 14 C-glucose was added to food and drinking water. The specific activity of tritium of tissues obtained was then corrected by the specific activity of 14 C in tissues in order to analyse the tritium incorporation from the same amount of ingested food and water. DNA-bound tritium after the ingestion of tritiated food was 4.6 times higher than that of tritiated water, while tissue-bound tritium was 2.2 times higher. The radiation dose to liver from tritium incorporated through food was two-fold higher than through tritiated water, which was mainly due to the high incorporation of tritium into DNA. Our results demonstrated that the dose calculation based on tissue-free-water tritium alone would underestimate the radiation exposure of the human population exposed to tritiated food. (author)

    Full Text Available Abstract Background We studied food consumption and nutrient intake in subjects with depressed mood, anxiety and insomnia as indices of compromised mental wellbeing. Methods The study population consisted of 29,133 male smokers aged 50 to 69 years who entered the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study in 1985–1988. This was a placebo-controlled trial to test whether supplementation with alpha-tocopherol or beta-carotene prevents lung cancer. At baseline 27,111 men completed a diet history questionnaire from which food and alcohol consumption and nutrient intake were calculated. The questionnaire on background and medical history included three symptoms on mental wellbeing, anxiety, depression and insomnia experienced in the past four months. Results Energy intake was higher in men who reported anxiety or depressed mood, and those reporting any such symptoms consumed more alcohol. Subjects reporting anxiety or depressed mood had higher intake of omega-3 fatty acids and omega-6 fatty acids. Conclusions Our findings conflict with the previous reports of beneficial effects of omega-3 fatty acids on mood.

    Dietary assessment methods are important tools for nutrition research. Online dietary assessment tools have the potential to become invaluable methods of assessing dietary intake because, compared with traditional methods, they have many advantages including the automatic storage of input data and the immediate generation of nutritional outputs. The aim of this study was to develop an online food frequency questionnaire (FFQ) for dietary data collection in the "Food4Me" study and to compare this with the validated European Prospective Investigation of Cancer (EPIC) Norfolk printed FFQ. The Food4Me FFQ used in this analysis was developed to consist of 157 food items. Standardized color photographs were incorporated in the development of the Food4Me FFQ to facilitate accurate quantification of the portion size of each food item. Participants were recruited in two centers (Dublin, Ireland and Reading, United Kingdom) and each received the online Food4Me FFQ and the printed EPIC-Norfolk FFQ in random order. Participants completed the Food4Me FFQ online and, for most food items, participants were requested to choose their usual serving size among seven possibilities from a range of portion size pictures. The level of agreement between the two methods was evaluated for both nutrient and food group intakes using the Bland and Altman method and classification into quartiles of daily intake. Correlations were calculated for nutrient and food group intakes. A total of 113 participants were recruited with a mean age of 30 (SD 10) years (40.7% male, 46/113; 59.3%, 67/113 female). Cross-classification into exact plus adjacent quartiles ranged from 77% to 97% at the nutrient level and 77% to 99% at the food group level. Agreement at the nutrient level was highest for alcohol (97%) and lowest for percent energy from polyunsaturated fatty acids (77%). Crude unadjusted correlations for nutrients ranged between .43 and .86. Agreement at the food group level was highest for "other

    Studies considering the impact of food-size variations on consumption have predominantly focused on portion size, whereas very little research has investigated variations in food-item size, especially at snacking occasions, and results have been contradictory. This study evaluated the effect of altering the size of food items (ie, small vs large candies) of equal-size food portions on short-term energy intake while snacking. The study used a between-subjects design (n=33) in a randomized experiment conducted in spring 2008. In a psychology laboratory (separate cubicles), participants (undergraduate psychology students, 29 of 33 female, mean age 20.3±2 years, mean body mass index 21.7±3.7) were offered unlimited consumption of candies while participating in an unrelated computerized experiment. For half of the subjects, items were cut in two to make the small food-item size. Food intake (weight in grams, kilocalories, and number of food items) was examined using analysis of variance. Results showed that decreasing the item size of candies led participants to decrease by half their gram weight intake, resulting in an energy intake decrease of 60 kcal compared to the other group. Appetite ratings and subject and food characteristics had no moderating effect. A cognitive bias could explain why people tend to consider that one unit of food (eg, 10 candies) is the appropriate amount to consume, regardless of the size of the food items in the unit. This study suggests a simple dietary strategy, decreasing food-item size without having to alter the portion size offered, may reduce energy intake at snacking occasions.

    Using dietary biomarkers in nutritional epidemiological studies may better capture exposure and improve the level at which diet-disease associations can be established and explored. Here, we aimed to identify and evaluate reproducibility of novel biomarkers of reported habitual food intake using targeted and non-targeted metabolomic blood profiling in a large twin cohort. Reported intakes of 71 food groups, determined by FFQ, were assessed against 601 fasting blood metabolites in over 3500 adult female twins from the TwinsUK cohort. For each metabolite, linear regression analysis was undertaken in the discovery group (excluding MZ twin pairs discordant [≥1 SD apart] for food group intake) with each food group as a predictor adjusting for age, batch effects, BMI, family relatedness and multiple testing (1.17x10-6 = 0.05/[71 food groups x 601 detected metabolites]). Significant results were then replicated (non-targeted: Pfood groups (Pfood intake for potential use in nutritional epidemiological studies. We compiled our findings into the DietMetab database (http://www.twinsuk.ac.uk/dietmetab-data/), an online tool to investigate our top associations.

    Poor food intake is known to lead to malnutrition in long-term care homes (LTCH), yet multilevel determinants of food intake are not fully understood, hampering development of interventions that can maintain the nutritional status of residents. This study measures energy and protein intake of LTCH residents, describes prevalence of diverse covariates, and the association of covariates with food intake. Multisite cross-sectional study. Thirty-two nursing homes from 4 provinces in Canada. From a sample of 639 residents (20 randomly selected per home), 628 with complete data were included in analyses. Three days of weighed food intake (main plate, estimated beverages and side dishes, snacks) were completed to measure energy and protein intake. Health records were reviewed for diagnoses, medications, and diet prescription. Mini-Nutritional Assessment-SF was used to determine nutritional risk. Oral health and dysphagia risk were assessed with standardized protocols. The Edinburgh-Feeding Questionnaire (Ed-FED) was used to identify eating challenges; mealtime interactions with staff were assessed with the Mealtime Relational Care Checklist. Mealtime observations recorded duration of meals and assistance received. Dining environments were assessed for physical features using the Dining Environment Audit Protocol, and the Mealtime Scan was used to record mealtime experience and ambiance. Staff completed the Person Directed Care questionnaire, and managers completed a survey describing features of the home and food services. Hierarchical multivariate regression determined predictors of energy and protein intake adjusted for other covariates. Average age of participants was 86.3 ± 7.8 years and 69% were female. Median energy intake was 1571.9 ± 411.93 kcal and protein 58.4 ± 18.02 g/d. There was a significant interaction between being prescribed a pureed/liquidized diet and eating challenges for energy intake. Age, number of eating challenges, pureed

    There is consistent evidence that the amount of food we consume can be influenced by the eating behaviour of other people. Some previous experimental studies reported that consumers are unaware of this influence on their behaviour. The present research tested whether people may be more aware of social influence on their eating than previously assumed. In two studies, participants (total n = 160) were exposed to information about the amount of snack food other people had been eating shortly before being served the same snack food and eating as much as they liked. After this, participants responded to questions regarding whether they thought their food intake had been socially influenced, and reported the reasons why they believed they had or had not been influenced. Of the 160 participants, 34% reported that they had been influenced, 10% were unsure and 56% reported they had not been influenced. Crucially, participants' reports of social influence appeared to be accurate; the food intake of participants reporting social influence was significantly affected by the amount of food other people had been eating, whereas the food intake of participants denying social influence was unaffected. Individuals may be more aware of the effect that social influence has on their eating behaviour than previously assumed. Further work is needed to identify the factors which determine whether people are susceptible to social influence on eating behaviour. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Previous studies conducted among pregnant women to test the accuracy of food frequency questionnaires (FFQ) for estimating food group intake were restricted to one specific trimester of pregnancy. The present study aimed to validate a FFQ for assessing the intake of food groups throughout pregnancy. In total, 75 adult pregnant Brazilian women were evaluated. Dietary intake was assessed by the FFQ (completed at the third trimester of pregnancy) and by three 24-h dietary recalls; one in each trimester of pregnancy. The food items were classified into 20 groups. Adequate deatenuatted Pearson correlation coefficients (>0.4) were observed for the intake of bread/cake, butter/margarine; milk/dairy products; soft drinks/artificial juices; coffee/tea; and pastries/sandwiches. The FFQ served poorly for estimating fruit and vegetable intake. A high percentage (>70%) of women were classified into the same or adjacent quartiles for estimates of cookies/crackers, butter/margarine, milk/dairy products, fruit juices, soft drinks/artificial juices, coffee/tea, roots, rice, beans, meat/chicken/sausages, fried foods, fish, eggs, sweets/sugars, and pastries/sandwiches. Nevertheless, the agreement of joint classification between the dietary methods was mostly into adjacent quartiles, rather than in the same quartile, and low values of kappa were found. The data reported in the present study suggest that the FFQ might not be an appropriate dietary method for evaluating food group intake throughout pregnancy. The joint classification between methods by categories of intake of food groups was mostly into adjacent quartiles, which could lead to attenuated associations when investigating diet-disease relationships during pregnancy. © 2014 The British Dietetic Association Ltd.

    Dietary restraint is known to break down in the face of tempting foods. Previous research suggests exposure to cues associated with slimming such as images or odours act as prompts to restrict intake of a tempting snack in dieters. The effects of consuming diet-congruent foods on subsequent intake of a meal have not yet been investigated. Thus, using a repeated measures design 26 female participants (dieters or non-dieters) consumed a diet-congruent (100 kcal salad), hedonic (100 kcal garlic bread) or neutral (0 kcal water) preload. A lexical decision task measured the salience of diet and hedonic thoughts and participants were then offered pizza as a main meal. Appetite sensations were measured throughout the study. Compared to the hedonic and neutral preload, a diet-congruent preload reduced dieters' entire meal intake by 21%. In contrast, non-dieters consumed 9% more in the hedonic preload condition compared to the neutral preload, yet showed no differences between the diet-congruent and other conditions. Salad lowered participants desire to eat and increased fullness compared to garlic bread and water preloads. Dieters were also less hungry after the salad compared to the garlic bread and water preloads. Consuming a diet-congruent first course may prompt lower intake at a meal, in part due to facilitating resolve to refrain from overeating a tempting second course. Copyright © 2013.

    2015-01-01

    Though the hunger-reduction phenomenon reported during ketogenic diets is well-known, the underlying molecular and cellular mechanisms remain uncertain. Ketosis has been demonstrated to exert an anorexigenic effect via cholecystokinin (CCK) release while reducing orexigenic signals e.g., via ghrelin. However, ketone bodies (KB) seem to be able to increase food intake through AMP-activated protein kinase (AMPK) phosphorylation, gamma-aminobutyric acid (GABA) and the release and production of adiponectin. The aim of this review is to provide a summary of our current knowledge of the effects of ketogenic diet (KD) on food control in an effort to unify the apparently contradictory data into a coherent picture.

    Dietary fat consumed during childhood and adolescence may be related to the development of cardiovascular and other chronic diseases in adulthood; however, there is a lack of information on specific fatty acid intakes and food sources in these populations. Our study aimed to assess fatty acid intakes in Australian adolescents, compare intakes with national guidelines, and identify major food sources of fatty acids. Dietary intake was assessed using measured 3-d records in 822 adolescents aged 13-15 y participating in The Western Australian Pregnancy Cohort (Raine) Study, Australia. Mean daily total fat intakes were 90 ± 25 g for boys and 73 ± 20 g for girls, with saturated fat contributing 14% of total energy intake. Mean contribution to daily energy intake for linoleic, alpha-linolenic, eicosapentaenoic, docosapentaenoic, and docosahexaenoic acids were 3.0%, 0.40%, 0.02%, 0.01%, and 0.04%, respectively, for boys, and 3.3%, 0.42%, 0.02%, 0.01%, and 0.05% for girls. To meet guidelines for chronic disease prevention, consumption of long-chain omega-3 fatty acids in this population may need to increase up to three-fold and the proportion of saturated fat decrease by one-third. Girls were more likely to achieve the guidelines. Major food sources were dairy products for total fat, saturated fat and alpha-linolenic acid, margarines for linoleic acid, and fish for long-chain omega-3 fatty acids. Results suggest that for this population, a higher dietary intake of long-chain omega-3 fatty acids, particularly for boys, and lower proportion of saturated fat is required to meet recommendations for prevention of chronic disease.

    Restricting fluids and foods during labour is common practice across many birth settings with some women only being allowed sips of water or ice chips. Restriction of oral intake may be unpleasant for some women, and may adversely influence their experience of labour. To determine the benefits and harms of oral fluid or food restriction during labour. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 June 2013) and reference lists of retrieved studies. Randomised controlled trials (RCTs) and quasi-RCTs of restricting fluids and food for women in labour compared with women free to eat and drink. Two review authors independently assessed the studies for inclusion, assessed risk of bias and carried out data extraction. We identified 19 studies of which we included five, involving 3130 women. We excluded eight studies, one awaits classification and five are ongoing studies. All the included studies looked at women in active labour and at low risk of potentially requiring a general anaesthetic. One study looked at complete restriction versus giving women the freedom to eat and drink at will; two studies looked at water only versus giving women specific fluids and foods and two studies looked at water only versus giving women carbohydrate drinks.When comparing any restriction of fluids and food versus women given some nutrition in labour, the meta-analysis was dominated by one study undertaken in a highly medicalised environment. There were no statistically significant differences identified in: caesarean section (average risk ratio (RR) 0.89, 95% confidence interval (CI) 0.63 to 1.25, five studies, 3103 women), operative vaginal births (average RR 0.98, 95% CI 0.88 to 1.10, five studies, 3103 women) and Apgar scores less than seven at five minutes (average RR 1.43, 95% CI 0.77 to 2.68, four studies, 2902 infants), nor in any of the other outcomes assessed. Women's views were not assessed. The pooled data were insufficient to assess the

    To examine the effects of calorie labeling on food selection and intake in dieters and non-dieters, and to explore whether expectations about food healthfulness moderate these effects. Participants were presented with a menu containing two items, a salad and a pasta dish. The menu had (a) no calorie information, (b) information that the salad was low in calories and the pasta was high in calories, (c) information that the salad was high in calories and the pasta was low in calories or (d) information that both were high in calories (study 2 only). Calorie labels influenced food selection for dieters, but not for non-dieters. Dieters were more likely to order salad when the salad was labeled as low in calories and more likely to order pasta, even high-calorie pasta, when the salad was labeled as high in calories. Participants who chose high-calorie foods over low-calorie foods did not eat less in response to calorie information, although non-dieters reduced their intake somewhat when calorie labels were put in the context of recommended daily calories. The results suggest that the rush to provide calorie information may not prove to be the best approach to fighting the obesity epidemic.

    Full Text Available Eating frequently during the day, or grazing, has been proposed to assist with managing food intake and weight. This systematic review assessed the effect of greater eating frequency (EF on intake and anthropometrics in human and animal experimental studies. Studies were identified through the PubMed electronic database. To be included, studies needed to be conducted in controlled settings or use methods that carefully monitored food intake, and measure food intake or anthropometrics. Studies using human or animal models of disease states (i.e., conditions influencing glucose or lipid metabolism, aside from being overweight or obese, were not included. The 25 reviewed studies (15 human and 10 animal studies contained varying study designs, EF manipulations (1 to 24 eating occasions per day, lengths of experimentation (230 min to 28 weeks, and sample sizes (3 to 56 participants/animals per condition. Studies were organized into four categories for reporting results: 1 human studies conducted in laboratory/metabolic ward settings; 2 human studies conducted in field settings; 3 animal studies with experimental periods 1 month. Out of the 13 studies reporting on consumption, 8 (61.5% found no significant effect of EF. Seventeen studies reported on anthropometrics, with 11 studies (64.7% finding no significant effect of EF. Future, adequately powered, studies should examine if other factors (i.e., disease states, physical activity, energy balance and weight status, long-term increased EF influence the relationship between increased EF and intake and/or anthropometrics.

    Heat production, which accounts for 0.6 of gross energy intake, is insufficiently represented in predictions of food intake. Especially when heat production is elevated (for example by lower temperature or poor feathering) the classical predictions based on body weight, body-weight change and egg mass are inadequate. Heat production was reliably estimated as [35.5-environmental temperature (degree C)] x [Defeathering (=%IBPW) + 21]. Including this term (PHP: predicted heat production) in equations predicting food intake significantly increased accuracy of prediction, especially under suboptimal conditions. Within the range of body weights tested (from 1.6 kg in brown layers to 2.8 kg in dwarf broiler breeders), body weight as an independent variable contributed little to the prediction of food intake; especially within strains its effect was better included in the intercept. Significantly reduced absolute values of residual food consumption were obtained over a wide range of conditions by using predictions of food intake based on body-weight change, egg mass, predicted heat production (PHP) and an intercept, instead of body weight, body-weight change, egg mass and an intercept.

    Recent studies link energy regulation to the circadian clock at the behavioral, physiological and molecular levels, emphasizing that the timing of food intake itself may have a significant role in obesity. In this regards, there is emerging literature in animals demonstrating a relationship between the timing of feeding and weight regulation. Unusual feeding time can produce a disruption of the circadian system which might produce unhealthy consequences in humans. In a longitudinal study, we recently showed that the timing of the main meal was predictive of weight loss during a 20-week dietary intervention and that this effect was independent from total 24-h caloric intake. The importance of caloric distribution across the day on weight loss therapy was supported by a recent 12-week experimental study showing that subjects assigned to high caloric intake during breakfast lost significantly more weight than those assigned to high caloric intake during the dinner. Furthermore, one of the most influential discoveries relevant for this area of research in the last years is the presence of an active circadian clock in different organs related to food intake. This is the case for stomach, intestine, pancreas or liver. New data also suggest that there is a temporal component in the regulation of adipose tissue functions. Thus, a specific temporal order in the daily patterns of adipose tissue genes appears to be crucial for adipose tissue to exclusively either accumulate fat or to mobilize fat at the proper time. Taking into account that feeding is the source of energy for adipose tissue, the time of feeding, particularly for high-energy content meals, may be decisive, and changes in this timing could have metabolic consequences for the development of obesity and for weight loss.

    There is emerging literature demonstrating a relationship between the timing of feeding and weight regulation in animals. However, whether the timing of food intake influences the success of a weight-loss diet in humans is unknown. To evaluate the role of food timing in weight-loss effectiveness in a sample of 420 individuals who followed a 20-week weight-loss treatment. Participants (49.5% female subjects; age (mean ± s.d.): 42 ± 11 years; BMI: 31.4 ± 5.4 kg m(-2)) were grouped in early eaters and late eaters, according to the timing of the main meal (lunch in this Mediterranean population). 51% of the subjects were early eaters and 49% were late eaters (lunch time before and after 1500 hours, respectively), energy intake and expenditure, appetite hormones, CLOCK genotype, sleep duration and chronotype were studied. Late lunch eaters lost less weight and displayed a slower weight-loss rate during the 20 weeks of treatment than early eaters (P=0.002). Surprisingly, energy intake, dietary composition, estimated energy expenditure, appetite hormones and sleep duration was similar between both groups. Nevertheless, late eaters were more evening types, had less energetic breakfasts and skipped breakfast more frequently that early eaters (all; Pmeal (P=0.015) with a higher frequency of minor allele (C) carriers among the late eaters (P=0.041). Neither sleep duration, nor CLOCK SNPs or morning/evening chronotype was independently associated with weight loss (all; P>0.05). Eating late may influence the success of weight-loss therapy. Novel therapeutic strategies should incorporate not only the caloric intake and macronutrient distribution - as is classically done - but also the timing of food.

    Objective To evaluate the association of intake of soya food, a rich source of phytoestrogens, with the risk of endometrial cancer. Design Population based case-control study, with detailed information on usual soya food intake over the past five years collected by face to face interview using a food frequency questionnaire. Setting Urban Shanghai, China. Participants 832 incident cases of endometrial cancer in women aged of 30 to 69 years diagnosed during 1997-2001 and identified from the Shanghai Cancer Registry; 846 control women frequency matched to cases on age and randomly selected from the Shanghai Residential Registry. Main outcome measures Odds ratios for risk of endometrial cancer in women with different intakes of soya foods. Results Regular consumption of soya foods, measured as amount of either soya protein or soya isoflavones, was inversely associated with the risk of endometrial cancer. Compared with women with the lowest quarter of intake, the adjusted odds ratio of endometrial cancer was reduced from 0.93 to 0.85 and 0.67 with increasing quarter of soya protein intake (P for trend 0.01). A similar inverse association was observed for soya isoflavones and soya fibre intake. The inverse association seemed to be more pronounced among women with high body mass index and waist:hip ratio. Conclusion Regular intake of soya foods is associated with a reduced risk of endometrial cancer. PMID:15136343

    Kendra is a 4-year-old girl with autism spectrum disorder (ASD) who presents for follow-up of feeding problems to her pediatric clinician. She is an only child in a family where both parents are scientists. Feeding concerns date to infancy, when she was diagnosed with Gastroesophageal Reflux Disease (GERD) associated with persistent bottle refusal and the acceptance of few pureed foods. At 13 months, milk and peanut allergies were diagnosed. Following a feeding clinic evaluation at 24 months, she was prescribed a soy milk supplement and an H2 blocker. There was no concern for oral-motor dysfunction. She was also referred to early intervention for feeding therapy. However, her parents terminated participation after 6 months because she became anxious and had tantrum prior to treatment groups.She was seen in another feeding program at 3 years; zinc, folate, thyroid, and a celiac panel were normal, and an endoscopy was negative for eosinophilic esophagitis. She began individual feeding therapy, where concerns for rigidity, difficulty transitioning, and limited peer interactions led to a neuropsychological evaluation. Kendra was diagnosed with an ASD and avoidant/restrictive food intake disorder (ARFID). Her cognitive skills were average, and expressive and receptive language skills were low average.Her diet consisted of French fries, Ritz crackers, pretzels, and 32 ounces of soy formula daily. She had stopped accepting Cheerios and saltines 2 months prior. She controlled other aspects of feeding, insisting on a specific parking spot at a fast food restaurant and drinking from a particular sippy cup. Her parents accepted these demands with concern about her caloric intake, which they tracked daily.Following diagnosis with ARFID, she resumed feeding therapy using a systematic desensitization approach with rewards. At the first session, she kissed and licked 2 new foods without gagging. Her mother appeared receptive to recommendations that included continuing the "food

    Simultaneous dietary achievement of a full set of nutritional recommendations is difficult. Diet optimization model using linear programming is a useful mathematical means of translating nutrient-based recommendations into realistic nutritionally-optimal food combinations incorporating local and culture-specific foods. We used this approach to explore optimal food intake patterns that meet the nutrient recommendations of the Dietary Reference Intakes (DRIs) while incorporating typical Japanese food selections. As observed intake values, we used the food and nutrient intake data of 92 women aged 31-69 years and 82 men aged 32-69 years living in three regions of Japan. Dietary data were collected with semi-weighed dietary record on four non-consecutive days in each season of the year (16 days total). The linear programming models were constructed to minimize the differences between observed and optimized food intake patterns while also meeting the DRIs for a set of 28 nutrients, setting energy equal to estimated requirements, and not exceeding typical quantities of each food consumed by each age (30-49 or 50-69 years) and gender group. We successfully developed mathematically optimized food intake patterns that met the DRIs for all 28 nutrients studied in each sex and age group. Achieving nutritional goals required minor modifications of existing diets in older groups, particularly women, while major modifications were required to increase intake of fruit and vegetables in younger groups of both sexes. Across all sex and age groups, optimized food intake patterns demanded greatly increased intake of whole grains and reduced-fat dairy products in place of intake of refined grains and full-fat dairy products. Salt intake goals were the most difficult to achieve, requiring marked reduction of salt-containing seasoning (65-80%) in all sex and age groups. Using a linear programming model, we identified optimal food intake patterns providing practical food choices and

    The validation of dietary assessment methods is critical in the evaluation of the relation between dietary intake and health. The aim of this study was to assess the validity of a food frequency questionnaire by comparing energy intake with energy expenditure measured with the doubly labelled water method. Total energy expenditure was measured with the doubly labelled water (DLW) method during a 10 day period. Furthermore, the subjects filled in the food frequency questionnaire about 18-35 days after the DLW phase of the study was completed. Twenty-one healthy, non-pregnant females volunteered to participate in the study; only 17 subjects completed the study. The group energy intake was on average 10% lower than the energy expenditure, but the difference was not statistically significant. However, there was a wide range in reporting accuracy: seven subjects were identified as acceptable reporters, eight as under-reporters and two were identified as over-reporters. The width of the 95% confidence limits of agreement in a Bland and Altman plot for energy intake and energy expenditure varied from -5 to 3 MJ. The data showed that there was substantial variability in the accuracy of the food frequency questionnaire at the individual level. Furthermore, the results showed that the questionnaire was more accurate for groups than individuals.

    Acute partial sleep deprivation increases plasma concentrations of ghrelin and decreases those of leptin. The objective was to observe modifications in energy intake and physical activity after acute partial sleep deprivation in healthy men. Twelve men [age: 22 +/- 3 y; body mass index (in kg/m(2)): 22.30 +/- 1.83] completed a randomized 2-condition crossover study. During the first night of each 48-h session, subjects had either approximately 8 h (from midnight to 0800) or approximately 4 h (from 0200 to 0600) of sleep. All foods consumed subsequently (jam on buttered toast for breakfast, buffet for lunch, and a free menu for dinner) were eaten ad libitum. Physical activity was recorded by an actimeter. Feelings of hunger, perceived pleasantness of the foods, desire to eat some foods, and sensation of sleepiness were also evaluated. In comparison with the 8-h sleep session, subjects consumed 559 +/- 617 kcal (ie, 22%) more energy on the day after sleep restriction (P < 0.01), and preprandial hunger was higher before breakfast (P < 0.001) and dinner (P < 0.05). No change in the perceived pleasantness of the foods or in the desire to eat the foods was observed. Physical activity from 1215 to 2015 was higher after sleep restriction than after 8 h of sleep (P < 0.01), even though the sensation of sleepiness was more marked (P < 0.01). One night of reduced sleep subsequently increased food intake and, to a lesser extent, estimated physical activity-related energy expenditure in healthy men. These experimental results, if confirmed by long-term energy balance measurements, suggest that sleep restriction could be a factor that promotes obesity. This trial was registered at clinicaltrials.gov as NCT00986492.

    The mammalian Target of Rapamycin (mTOR) protein is a serine-threonine kinase that regulates cell-cycle progression and growth by sensing changes in energy status. We demonstrated that mTOR signaling plays a role in the brain mechanisms that respond to nutrient availability, regulating energy balance. In the rat, mTOR signaling is controlled by energy status in specific regions of the hypothalamus and colocalizes with neuropeptide Y and proopiomelanocortin neurons in the arcuate nucleus. Central administration of leucine increases hypothalamic mTOR signaling and decreases food intake and body weight. The hormone leptin increases hypothalamic mTOR activity, and the inhibition of mTOR signaling blunts leptin's anorectic effect. Thus, mTOR is a cellular fuel sensor whose hypothalamic activity is directly tied to the regulation of energy intake.

However, EF problems may not directly affect HCLN intake across time, except when problems are associated with child perception of more frequent parent consumption of convenience foods.

    Vegetable intake seems to play a protective role against major lifestyle diseases. Despite this, the Danish population usually eats far less than the recommended daily intake. The present study focused on the intake of 17 coarse vegetables and the potential barriers limiting their intake. The present study drew upon a large Danish survey (n = 1079) to study the intake of coarse vegetables among Danish consumers. Four population clusters were identified based on their intake of 17 different coarse vegetables, and profiled according to hedonics, socio-demographic, health, and food lifestyle factors. The four clusters were characterized by a very low intake frequency of coarse vegetables ('low frequency'), a low intake frequency of coarse vegetables; but high intake frequency of carrots ('carrot eaters'), a moderate coarse vegetable intake frequency and high intake frequency of beetroot ('beetroot eaters'), and a high intake frequency of all coarse vegetables ('high frequency'). There was a relationship between reported liking and reported intake frequency for all tested vegetables. Preference for foods with a sweet, salty or bitter taste, in general, was also identified to be decisive for the reported vegetable intake, as these differed across the clusters. Each cluster had distinct socio-demographic, health and food lifestyle profiles. 'Low frequency' was characterized by uninvolved consumers with lack of interest in food, 'carrot eaters' vegetable intake was driven by health aspects, 'beetroot eaters' were characterized as traditional food consumers, and 'high frequency' were individuals with a strong food engagement and high vegetable liking. 'Low frequency' identified more barriers than other consumer clusters and specifically regarded low availability of pre-cut/prepared coarse vegetables on the market as a barrier. Across all clusters a low culinary knowledge was identified as the main barrier. Copyright © 2015 Elsevier Ltd. All rights reserved.

  12. Activation of temperature-sensitive TRPV1-like receptors in ARC POMC neurons reduces food intake.

    Full Text Available Proopiomelanocortin (POMC neurons in the arcuate nucleus of the hypothalamus (ARC respond to numerous hormonal and neural signals, resulting in changes in food intake. Here, we demonstrate that ARC POMC neurons express capsaicin-sensitive transient receptor potential vanilloid 1 receptor (TRPV1-like receptors. To show expression of TRPV1-like receptors in ARC POMC neurons, we use single-cell reverse transcription-polymerase chain reaction (RT-PCR, immunohistochemistry, electrophysiology, TRPV1 knock-out (KO, and TRPV1-Cre knock-in mice. A small elevation of temperature in the physiological range is enough to depolarize ARC POMC neurons. This depolarization is blocked by the TRPV1 receptor antagonist and by Trpv1 gene knockdown. Capsaicin-induced activation reduces food intake that is abolished by a melanocortin receptor antagonist. To selectively stimulate TRPV1-like receptor-expressing ARC POMC neurons in the ARC, we generate an adeno-associated virus serotype 5 (AAV5 carrying a Cre-dependent channelrhodopsin-2 (ChR2-enhanced yellow fluorescent protein (eYFP expression cassette under the control of the two neuronal POMC enhancers (nPEs. Optogenetic stimulation of TRPV1-like receptor-expressing POMC neurons decreases food intake. Hypothalamic temperature is rapidly elevated and reaches to approximately 39 °C during treadmill running. This elevation is associated with a reduction in food intake. Knockdown of the Trpv1 gene exclusively in ARC POMC neurons blocks the feeding inhibition produced by increased hypothalamic temperature. Taken together, our findings identify a melanocortinergic circuit that links acute elevations in hypothalamic temperature with acute reductions in food intake.

    Western-style fast food contributes to a dietary pattern portending poor cardiometabolic health in the United States. With globalization, this way of eating is becoming more common in developing and recently developed populations. We examined the association of Western-style fast food intake with risk of incident type 2 diabetes mellitus and coronary heart disease mortality in Chinese Singaporeans. This analysis included men and women 45 to 74 years of age who enrolled in the Singapore Chinese Health Study from 1993 to 1998. For CHD mortality, 52 584 participants were included and 1397 deaths were identified through December 31, 2009, via registry linkage. For type 2 diabetes mellitus, 43 176 participants were included and 2252 cases were identified during the follow-up interview (1999-2004) and validated. Hazard ratios for incident type 2 diabetes mellitus and coronary heart disease mortality were estimated with thorough adjustment for demographic, lifestyle, and dietary factors. Chinese Singaporeans with relatively frequent intake of Western-style fast food items (≥2 times per week) had an increased risk of developing type 2 diabetes mellitus (hazard ratio, 1.27; 95% confidence interval, 1.03-1.54) and dying of coronary heart disease (hazard ratio, 1.56; 95% confidence interval, 1.18-2.06) relative to their peers with little or no reported intake. These associations were not materially altered by adjustments for overall dietary pattern, energy intake, and body mass index. Western-style fast food intake is associated with increased risk of developing type 2 diabetes mellitus and of coronary heart disease mortality in an Eastern population. These findings suggest the need for further attention to global dietary acculturation in the context of ongoing epidemiological and nutrition transitions.

    Communications to stimulate weight loss include exercise-promotion messages that often produce unsatisfactory results due to compensatory behavioral and metabolic mechanisms triggered by physical activity. This research investigated potential automatic facilitation of eating immediately after exercise messages in the absence of actual exercise. Two controlled experiments demonstrated greater than control food intake following exposure to print messages typical of exercise campaigns as well as subliminal presentation of action words associated with exercise (e.g., "active"). These inadvertent effects may explain the limited efficacy of exercise-promotion programs for weight loss, particularly when systematic dietary guidelines are absent.

    Understanding dietary habits of women after breast cancer is a critical first step in developing nutrition guidelines that will support weight management and optimal health in survivorship; however, limited data are available. The objective of this study was to describe changes in diet among breast cancer survivors in the first year after treatment, and to evaluate these changes in the context of current dietary intake. Changes in diet were assessed in 28 early stage breast cancer survivors, using a self-reported survey in which women identified changes in food intake since their diagnosis. Current dietary intake was estimated from 3-day food records and described relative to current recommendations. The majority of women reported changes in diet after diagnosis, most common being an increase in vegetables/fruit and fish, lower intake of red meat, and reduced alcohol. Many women reported that these changes were initiated during active treatment. Dietary changes were largely consistent with current recommendations for cancer prevention; however, some women were still above the guidelines for total and saturated fat, and many were below recommendations for vegetables/fruit, milk/alternatives, calcium, and vitamin D. Evidence that some women are willing and able to initiate positive changes in diet early in the treatment trajectory suggests that early intervention may be effective in promoting dietary habits that will assist with weight management and overall health. Data on current dietary intake highlights several possible targets for dietary intervention in this population.

    On a population level, dietary improvement strategies have had limited success in preventing the surge in overweight and obesity or reducing risk factors for chronic disease. While numerous multi-component studies have examined whole-of-diet strategies, and single component (i.e. discrete) dietary intervention strategies have targeted an increase in core foods (e.g. fruits, vegetables, dairy), there is a paucity of evidence on the effectiveness of dietary intervention strategies targeting a decrease in discretionary choices. The aim of this review was to identify dietary intervention strategies that are potentially relevant to reducing intake of discretionary choices in 2-65 year olds. A scoping review was carried out to map the literature on key discrete dietary intervention strategies that are potentially applicable to reducing discretionary choices, and to identify the targeted health/nutrition effects (e.g. improve nutrient intake, decrease sugar intake, and reduce body weight) of these strategies. Studies conducted in participants aged 2-65 years and published in English by July 20, 2015, were located through electronic searches including the Cochrane Library, Medline, Embase, CINAHL, and Scopus. Three thousand two hundred and eighty three studies were identified from the search, of which 44 met the selection criteria. The dietary intervention strategies included reformulation (n = 13), substitution (n = 5), restriction/elimination (n = 9), supplementation (n = 13), and nutrition education/messages (n = 4). The key findings of the review were: restricting portion size was consistently beneficial for reducing energy intake in the acute setting; reformulating foods from higher fat to lower fat could be useful to reduce saturated fat intake; substituting discretionary choices for high fibre snacks, fruit, or low/no-calorie beverages may be an effective strategy for reducing energy intake; supplementing nutrient dense foods such as nuts and

    Full Text Available Using dietary biomarkers in nutritional epidemiological studies may better capture exposure and improve the level at which diet-disease associations can be established and explored. Here, we aimed to identify and evaluate reproducibility of novel biomarkers of reported habitual food intake using targeted and non-targeted metabolomic blood profiling in a large twin cohort. Reported intakes of 71 food groups, determined by FFQ, were assessed against 601 fasting blood metabolites in over 3500 adult female twins from the TwinsUK cohort. For each metabolite, linear regression analysis was undertaken in the discovery group (excluding MZ twin pairs discordant [≥1 SD apart] for food group intake with each food group as a predictor adjusting for age, batch effects, BMI, family relatedness and multiple testing (1.17x10-6 = 0.05/[71 food groups x 601 detected metabolites]. Significant results were then replicated (non-targeted: P<0.05; targeted: same direction in the MZ discordant twin group and results from both analyses meta-analyzed. We identified and replicated 180 significant associations with 39 food groups (P<1.17x10-6, overall consisting of 106 different metabolites (74 known and 32 unknown, including 73 novel associations. In particular we identified trans-4-hydroxyproline as a potential marker of red meat intake (0.075[0.009]; P = 1.08x10-17, ergothioneine as a marker of mushroom consumption (0.181[0.019]; P = 5.93x10-22, and three potential markers of fruit consumption (top association: apple and pears: including metabolites derived from gut bacterial transformation of phenolic compounds, 3-phenylpropionate (0.024[0.004]; P = 1.24x10-8 and indolepropionate (0.026[0.004]; P = 2.39x10-9, and threitol (0.033[0.003]; P = 1.69x10-21.

This prospective study was conducted to determine the relation between dietary fat consumption level, its food sources and the assisted reproduction parameters. A prospective study was conducted on 240 infertile women. In assisted reproduction treatment cycle, fat consumption and major food sources over the previous three months were identified. The number of retrieved oocytes, metaphase ΙΙ stage oocytes numbers, fertilization rate, embryo quality and clinical pregnancy rate were also determined. The data were analyzed using multiple regression, binary logistic regression, chi-square and t-test. The p-value of less than 0.05 was considered significant. Total fat intake adjusted for age, body mass index, physical activity and etiology of infertility was positively associated with the number of retrieved oocytes and inversely associated with the high embryo quality rate. An inverse association was observed between sausage and turkey ham intake and the number of retrieved oocytes. Also, oil intake level had an inverse association with good cleavage rate. The results revealed that higher levels of fat consumption tend to increase the number of retrieved oocytes and were adversely related to embryonic development. Among food sources of fat, vegetable oil, sausage and turkey ham intake may adversely affect assisted reproduction parameters.

    Novel ways to increase liking and intake of food are needed to encourage acceptance of healthier food. How enjoyable we remember food to have been is likely to be a significant predictor of food choice. Two studies examined whether remembered enjoyment of eating a food can be increased and whether this makes individuals more likely to eat that food in the future. In Study One, a simple manipulation of instructing participants to rehearse what they found enjoyable about a food immediately after eating it was used to increase remembered enjoyment (relative to controls). In a separate study; Study Two, the effect of increasing remembered enjoyment on food choice was tested by examining whether the manipulation to increase remembered enjoyment resulted in participants choosing to eat more of a food as part of a later buffet lunch. The experimental manipulation increased remembered enjoyment for the food (Study One). A change in remembered enjoyment was shown to have a significant effect on the amount of a food participants chose to eat the following day for lunch (Study Two). The present studies suggest that remembered enjoyment can be increased via a simple act of rehearsal, resulting in a later increase in the amount of food chosen and eaten. Interventions based on altering remembered enjoyment of healthy food choices warrant further investigation.

    Full Text Available Excessive food/energy intake is linked to obesity and metabolic disorders, such as diabetes. The hypothalamus in the brain plays a critical role in the control of food intake and peripheral metabolism. The signaling pathways in hypothalamic neurons that regulate food intake and peripheral metabolism need to be better understood for developing pharmacological interventions to manage eating behavior and obesity. Mammalian target of rapamycin (mTOR, a serine/threonine kinase, is a master regulator of cellular metabolism in different cell types. Pharmacological manipulations of mTOR complex 1 (mTORC1 activity in hypothalamic neurons alter food intake and body weight. Our previous study identified Rheb1 (Ras homolog enriched in brain 1 as an essential activator of mTORC1 activity in the brain. Here we examine whether central Rheb1 regulates food intake and peripheral metabolism through mTORC1 signaling. We find that genetic deletion of Rheb1 in the brain causes a reduction in mTORC1 activity and impairs normal food intake. As a result, Rheb1 knockout mice exhibit hypoglycemia and increased lipid mobilization in adipose tissue and ketogenesis in the liver. Our work highlights the importance of central Rheb1 signaling in euglycemia and energy homeostasis in animals.

    Adolescence, with its change in dietary habits, is likely to be a vulnerable period in the onset of obesity. It is considered that peers have an important role to play on adolescents' diet, however, limited research has examined the role of peers in this context. This study examined the relationship between self-efficacy for healthy eating, parent and peer support for healthy and unhealthy eating and food intake patterns. Participants were 264 boys and 219 girls (N=483), aged 13-18years, recruited from post-primary schools in Ireland. Self-report measures assessed self-efficacy, parent and peer support for healthy eating, and for unhealthy eating. Dietary pattern analysis, a popular alternative to traditional methods used in nutritional research, was conducted on a FFQ to derive food intake patterns. Two patterns were identified labelled 'healthy food intake' and 'unhealthy food intake'. Multi-group modelling was used to evaluate whether the hypothesized model of factors related to dietary patterns differed by gender. The multi-group model fit the data well, with only one path shown to differ by gender. Lower self-efficacy for healthy eating and higher peer support for unhealthy eating were associated with 'unhealthy food intake'. Higher self-efficacy was associated with 'healthy food intake'. Prevention programs that target self-efficacy for eating and peer support for unhealthy eating may be beneficial in improving dietary choices among adolescents. Copyright © 2012 Elsevier Ltd.

    Full Text Available Dairy nutrients, such as calcium, are particularly important in adolescence, a critical time for growth and development. There are limited Australian data following individuals through adolescence, evaluating changes in dairy nutrient and dairy product consumption. We used a validated food frequency questionnaire to investigate consumption in adolescents participating in both the 14 and 17 year follow-ups of the Western Australian Pregnancy Cohort (Raine Study. Most adolescents did not reach age and gender specific recommended daily intakes for calcium or magnesium at 14 years, and this decreased as they aged to 17 years (from 33.0% to 29.2% meeting for calcium, P < 0.05, and from 33.6% to 20.5% meeting for magnesium, P < 0.01. Mean intakes of calcium, potassium, riboflavin and vitamin A also decreased with age (P < 0.01. Mean dairy intake decreased from 536 ± 343 g/day to 464 ± 339 g/day (P < 0.01, due mostly to a decrease in regular milk, although flavoured milk consumption increased in boys. Cheese and butter were the only products to show a significantly increased consumption over the period. Girls decreased from 2.2 to 1.9 serves/day of dairy, while boys remained relatively steady at 2.9 to 2.8 serves/day. Our findings suggest that dairy product consumption decreases over adolescence. This may have implications for bone mass, development and later health.

'Low frequency' was characterized by uninvolved consumers with lack of interest in food, 'carrot eaters' vegetable intake was driven by health aspects....... The present study drew upon a large Danish survey (n = 1079) to study the intake of coarse vegetables among Danish consumers. Four population clusters were identified based on their intake of 17 different coarse vegetables, and profiled according to hedonics, socio-demographic, health, and food lifestyle...... ('beetroot eaters'), and a high intake frequency of all coarse vegetables ('high frequency'). There was a relationship between reported liking and reported intake frequency for all tested vegetables. Preference for foods with a sweet, salty or bitter taste, in general, was also identified to be decisive...

    Identification of new biomarkers of food and nutrient intake has developed fast over the past two decades and could potentially provide important new tools for compliance monitoring and dietary intake assessment in nutrition and health science. In recent years, metabolomics has played an important role in identifying a large number of putative biomarkers of food intake (BFIs). However, the large body of scientific literature on potential BFIs outside the metabolomics area should also be taken into account. In particular, we believe that extensive literature reviews should be conducted and that the quality of all suggested biomarkers should be systematically evaluated. In order to cover the literature on BFIs in the most appropriate and consistent manner, there is a need for appropriate guidelines on this topic. These guidelines should build upon guidelines in related areas of science while targeting the special needs of biomarker methodology. This document provides a guideline for conducting an extensive literature search on BFIs, which will provide the basis to systematically validate BFIs. This procedure will help to prioritize future work on the identification of new potential biomarkers and on validating these as well as other biomarker candidates, thereby providing better tools for future studies in nutrition and health.

    Previous research has shown that oral processing characteristics like bite size and oral residence duration are related to the satiating efficiency of foods. Oral processing characteristics are influenced by food texture. Very little research has been done on the effect of food texture within solid foods on energy intake. The first objective was to investigate the effect of hardness of food on energy intake at lunch, and to link this effect to differences in food oral processing characteristics. The second objective was to investigate whether the reduction in energy intake at lunch will be compensated for in the subsequent dinner. Fifty subjects (11 male, BMI: 21±2 kg/m2, age: 24±2 y) participated in a cross-over study in which they consumed ad libitum from a lunch with soft foods or hard foods on two separate days. Oral processing characteristics at lunch were assessed by coding video records. Later on the same days, subjects consumed dinner ad libitum. Hard foods led to a ∼13% lower energy intake at lunch compared to soft foods (Pfoods were consumed with smaller bites, longer oral duration per gram food, and more chewing per gram food compared to the soft foods (Pfoods led to reduced energy intake compared to soft foods, and this reduction in energy intake was sustained over the next meal. We argue that the differences in oral processing characteristics produced by the hardness of the foods explain the effect on intake. The sustained reduction in energy intake suggests that changes in food texture can be a helpful tool in reducing the overall daily energy intake.

    Background: Food reinforcement, ie, motivation to obtain food, is associated with energy intake and obesity. Finding ways to decrease the reinforcing value of unhealthy foods may help with adherence to diets and maintenance of weight loss. Our previous study in nonobese adults showed that daily consumption of the same snack food (food consumed apart from meals) for 14 d significantly decreased its reinforcing value.

    Nursing facilities often provide enhanced or fortified foods as part of a "food-first" approach to increasing nutrient intakes in residents with inadequate intakes or who are experiencing weight loss. The study objective was to determine whether energy and protein enhancement of a small number of menu items would result in increased three-meal (breakfast, lunch, and supper) calorie and protein intakes in long-term care residents. A randomized cross-over design was used to compare investigator-weighed food intakes under three menu conditions: control (no meals enhanced); lunch only enhanced; and both breakfast and lunch enhanced. Two breakfast foods (juice and hot cereal) and two lunch foods (soup and potato side dish) were chosen for enhancement. Participants were 33 nursing home residents from a facility in South Florida (average age=87.3 years). Repeated-measures analysis of variance was used to test the effects of the within-subjects factor (control, lunch enhanced, breakfast and lunch enhanced conditions), the between-subjects factor (smaller vs bigger eater), and the interaction on intakes (gram, kilocalories, and protein). Results revealed that bigger eaters consumed considerably more calories when breakfast foods, but not lunch foods, were enhanced. Smaller eaters achieved an increase in energy intake when either breakfast or lunch was enhanced. Overall daily protein intakes were not substantially increased by food enhancement. These data suggest that for an enhanced food program to be most effective for smaller eaters, who are at greatest risk for undernutrition and weight loss, it should include several enhanced foods at more than one meal.

  13. Hypothalamic eIF2α Signaling Regulates Food Intake

    Directory of Open Access Journals (Sweden)

    Anne-Catherine Maurin

    2014-02-01

    Full Text Available The reversible phosphorylation of the α subunit of eukaryotic initiation factor 2 (eIF2α is a highly conserved signal implicated in the cellular adaptation to numerous stresses such as the one caused by amino acid limitation. In response to dietary amino acid deficiency, the brain-specific activation of the eIF2α kinase GCN2 leads to food intake inhibition. We report here that GCN2 is rapidly activated in the mediobasal hypothalamus (MBH after consumption of a leucine-deficient diet. Furthermore, knockdown of GCN2 in this particular area shows that MBH GCN2 activity controls the onset of the aversive response. Importantly, pharmacological experiments demonstrate that the sole phosphorylation of eIF2α in the MBH is sufficient to regulate food intake. eIF2α signaling being at the crossroad of stress pathways activated in several pathological states, our study indicates that hypothalamic eIF2α phosphorylation could play a critical role in the onset of anorexia associated with certain diseases.

    To evaluate the separate contributions of distension and nutrient stimulation of the stomach to the inhibition of short-term food intake and, particularly, to reassess previous analyses based on the inflatable gastrointestinal cuff, four experiments were performed. Rats equipped with pyloric cuffs and indwelling gastric catheters consumed a liquid diet ad libitum. Their consumption during short-term (30 min) feeding bout was measured after gastric infusions on cuff-open and cuff-closed trials. Animals taking meals (approximately 5 ml) with cuffs closed immediately after receiving intragastric infusions of 2.5, 5, 7.5, or 10 ml of normal saline exhibited both suppression at the smallest infusion and a dose-dependent reduction across the other volumes (experiment 1). Additionally, when the test diet concentration was varied, animals with their cuffs closed consumed a constant volume, not a constant number of calories (experiment 2). Furthermore, cuff-closed animals exhibited no more suppression to 5-ml intragastric infusions of nutrients (including, on different trials, 50 and 100% Isocal diet; 10, 20, and 40% glucose; and 40% sucrose and 40% fructose) than to the same volume of saline (experiments 3 and 4). In contrast, on cuff-open trials in which gastric contents could empty into the duodenum, these same nutrient loads were more effective (except fructose) than saline in producing suppression of food intake. In summary, although both limited gastric distension with the pylorus occluded and intestinal nutrient stimulation with the cuff open effectively reduced intake, cuff-closed gastric loads of mixed macronutrients or carbohydrate solutions of 2-8 kcal, pH from 5.8 to 6.7, and osmolarities between 117 and 2,294 mosM/kg produced only the distension-based suppression generated by the same volume of saline.

    Determine the influence of experience with consistent or inconsistent relationships between the sensory properties of snack foods and their caloric consequences on the control of food intake or body weight in rats. Rats received plain and BBQ flavored potato chips as a dietary supplement, along with ad lib rat chow. For some rats the potato chips were a consistent source of high fat and high calories (regular potato chips). For other rats, the chips provided high fat and high calories on some occasions (regular potato chips) and provided no digestible fat and fewer calories at other times (light potato chips manufactured with a fat substitute). Thus, animals in the first group were given experiences that the sensory properties of potato chips were strong predictors of high calories, while animals in the second group were given experiences that the sensory properties of potato chips were not predictors of high calories. Juvenile and adult male Sprague-Dawley rats. Following exposure to varying potato chip-calorie contingencies, intake of a novel, high-fat snack food and subsequent chow intake were assessed. Body weight gain and body composition as measured by DEXA were also measured. In juvenile animals, exposure to a consistent relationship between potato chips and calories resulted in reduced chow intake, both when no chips were provided and following consumption of a novel high-fat, high-calorie snack chip. Long-term experience with these contingencies did not affect body weight gain or body composition in juveniles. In adult rats, exposure to an inconsistent relationship between potato chips and calories resulted in increased consumption of a novel high-fat, high-calorie snack chip premeal along with impaired compensation for the calories contained in the premeal. Consumption of foods in which the sensory properties are poor predictors of caloric consequences may alter subsequent food intake.

    to identify changes in the food intake patterns among overweight children and teenagers, treated at a reference medical centre. the method used is that of a cohort study, between April 2010 and April 2011. A total of 109 children and teenagers, either obese or overweight, took part in the study. The population was divided into two subgroups depending on the permanence period (more than 6 months, and less than 6 months off the treatment). The chi-square test and logistic regression were carried out. the group which had been longer off the treatment tended to consume more soft drinks, pasta and fried foods, and less fruit and vegetables. The group with less time showed an improvement, with a reduction of consumption of soft drinks and other goodies. There was confirmation of an increased risk for consumption of soft drinks, pasta and goodies in general, as also detachment from the treatment in adolescence. The group with a longer period of monitoring has had a positive change in food intake frequency. The main contribution made by this study is that of showing that multiprofessional treatment, including some nursing care, is efficient in progressively changing the food intake of children and adolescents who are overweight.

    Most previous studies of parental influences on children's diets included just a single or a few types of food parenting practices, while parents actually employ multiple types of practices. Our objective was to investigate the clustering of parents regarding food parenting practices and to characterize the clusters in terms of background characteristics and children's intake of energy-dense snack foods. A sample of Dutch parents of children aged 4-12 was recruited by a research agency to fill out an online questionnaire. A hierarchical cluster analysis (n = 888) was performed, followed by k-means clustering. ANOVAs, ANCOVAs and chi-square tests were used to investigate associations between cluster membership, parental and child background characteristics, as well as children's intake of energy-dense snack foods. Four distinct patterns were discovered: "high covert control and rewarding", "low covert control and non-rewarding", "high involvement and supportive" and "low involvement and indulgent". The "high involvement and supportive" cluster was found to be most favorable in terms of children's intake. Several background factors characterized cluster membership. This study expands the current knowledge about parental influences on children's diets. Interventions should focus on increasing parental involvement in food parenting.

    Previous research indicates that many people perceive themselves to be addicted to food. These 'self-perceived food addicts' may demonstrate aberrant eating patterns which put them at greater risk of overeating. However this is yet to be empirically investigated. The current study investigated whether self-perceived food addicts would exhibit higher food reward and calorie intake in a laboratory context relative to self-perceived non-addicts. A secondary aim was to investigate whether self-perceived food addicts would demonstrate increased food liking and/or increased hunger ratings. Finally, we explored whether self-perceived food addicts demonstrate patterns of aberrant eating, beyond that predicted by measures of trait dietary disinhibition and restraint. Female participants (self-perceived food addicts n = 31, non-addicts n = 29) completed measures of hunger, food reward (desire-to-eat, willingness-to-pay ratings, and an operant response task) and liking for high- and low-fat foods. Participants completed all measures when they were hungry, and again when they were satiated after consuming a fixed-lunch meal. Finally, participants were provided with ad-libitum access to high-and low-fat foods. Results indicated that self-perceived food addicts consumed more calories from high-fat food compared to non-addicts, despite the absence of any between-group differences in hunger or overall liking ratings. Self-perceived food addicts also displayed higher desire-to-eat ratings across foods compared to non-addicts, but groups did not differ on other measures of food reward. However, the differences in calorie intake and desire-to-eat between self-perceived food addicts and non-addicts were no longer significant after controlling for dietary disinhibition and restraint. These findings suggest that self-perceived food addicts experience food as more rewarding and have a tendency to overeat. However, this may be attributable to increased dietary disinhibition and

    Aluminium was measured in 2580 samples of 15 food groups and dietary exposure was estimated. Samples were purchased and analysed during 2010 to 2014. High aluminium levels were found in jellyfish (mean 4862 mg/kg), laver (mean 455.2 mg/kg) and fried twisted cruller (mean 392.4 mg/kg). Dietary exposure to aluminium was estimated for Zhejiang residents. The average dietary exposure to aluminium via 15 food groups in Zhejiang Province was 1.15 mg/kg bw/week, which is below the provisional tolerable weekly intake of 2 mg/kg bw /week. Jellyfish is the main Al contributor, providing 37.6% of the daily intake via these 15 food groups. This study provided new information on aluminium levels and assessment of aluminium (Al) dietary exposure in Zhejiang Province of China.

    Background Appetite is frequently affected in cancer patients leading to anorexia and consequently insufficient food intake. In this study, we report on hypothalamic gene expression profile of a cancer-cachectic mouse model with increased food intake. In this model, mice bearing C26 tumour have an increased food intake subsequently to the loss of body weight. We hypothesise that in this model, appetite-regulating systems in the hypothalamus, which apparently fail in anorexia, are still able t...

    Dietary intake of tin (Sn) may be increased in some children in kindergartens in Korea. The present study was intended to examine this possibility and clarify the extent of the elevation. 24-hour food duplicate and spot urine samples were collected in 2003-2004 from 108 4-6-year-old children (boys and girls combined) in 4 kindergartens (1 in Seoul and 3 in Jeju Island), as reported in a previous publication. These samples were employed in the present analyses to examine tin levels in the diet (including beverages) (Sn-D). A portion of the samples were wet-ashed, and the liquid samples were analyzed for Sn by the ICP-MS method. For statistical evaluation, χ (2) method and Smirnov's test for extreme value were used. Sn-D in the 108 cases distributed as extremely biased, and could be divided into two groups, i.e., those with 10 μg/day (for 10%). Sn-D in the former group was distributed quasi-normally with an AM (median) of 2.9 (2.5) μg/day. The maximum in the latter group was 3012 μg/day. No correlation was detected between Sn-D and Sn in urine (Sn-U). Comparison of the findings with published articles strongly suggested that the high Sn-D was due to consumption of foods (including beverages) preserved in tin-plated cans. No positive confirmation was however possible due to insufficient information on food records. About 10% of children surveyed had elevated Sn-D (up to 3 mg/day). It was quite possible that high Sn-D was associated with tin-canned food intake.

    Guan, Vivienne X; Kent, Katherine

    2017-01-01

    Introduction Dietary phytochemicals are found in plant-based foods such as fruits, vegetables and grains and may be categorised in a nested hierarchical manner with many hundred individual phytochemicals identified to date. To associate phytochemical intakes with positive health outcomes, a fundamental step is to accurately estimate the dietary phytochemical intake from foods reported. The purpose of this systematic review protocol is to describe the process to be undertaken to summarise the evidence for food-based dietary phytochemical intakes and health outcomes for adults. Methods and analysis The review will be undertaken following the PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions using the Review Manager software. Phytochemical subclasses (phenolic acids, flavanols, etc) will be used to search for relevant studies using the Web of Science and Scopus scientific databases. The retrieved studies will be screened based on inclusion of natural whole food items and health outcomes. Phytochemical studies related to cardiovascular disease, cancer, overweight, glucose tolerance, digestive, reproductive, macular and bone health and mental disorders, fatigue and immunity will be examined based on prior scoping. The evidence will be aggregated by the food types and health outcomes. Comparison of differences in the outcomes for randomised controlled trials and observational studies will be undertaken. The strength of the review lies in its focus on whole food items and health conditions rather than one type of phytochemical related to one single health condition. Subgroup and sensitivity analyses will be conducted where an adequate number of publications are found per phytochemical subclass. Dissemination By comparing the outcomes from experimental and observational studies, the review will determine whether the overall conclusions related to the phytochemical subclasses are the same between study types for the identified health

    Statistical methods to model the usual dietary intake of foods in a population generally ignore the additional information on the never-consumers. The objective of this study is to determine the added value of Food Frequency Questionnaire (FFQ) data allowing distinguishing the never-consumers from the non-consumers while modeling the usual intake distribution. Three food items with a different proportion of never-consumers were selected from the database of the Belgian food consumption survey of 2004 ( N  = 3200). The usual intake distribution for these food items was modeled with the Statistical Program for Analysis of Dietary Exposure (SPADE) and modeling parameters were extracted. These parameters were used to simulate (a) a new database with two 24-h recalls per respondent and (b) a "true" usual intake distribution. The usual intake distribution from the new database was obtained by modeling the 24-h recalls with SPADE, once without and once with the inclusion of the FFQ data on the never-consumers. Ratios were calculated for the different percentiles of the usual intake distribution: the modeled usual intake (g/day) (for both SPADE with and without the inclusion of FFQ data on never-consumers) was divided by the corresponding percentile of the simulated "true" usual intake (g/day). The closer the ratio is to one, the better the model fits the data. Inclusion of the FFQ information to identify the never-consumers did not improve the estimation of the higher percentiles of the usual intake distribution. However, taking into account this FFQ information improved the estimation of the lower percentiles of the usual intake distribution even when the proportion of never-consumers was low. The inclusion of FFQ information to identify the never-consumers is beneficial when interested in the whole usual intake distribution or in the lower percentiles only, no matter how low the proportion of never-consumers for that food item may be. However, when interest is only in

    Food purchasing is considered a key mediator between the food environment and eating behavior, and food purchasing patterns are increasingly measured in epidemiologic and intervention studies. However, the extent to which food purchases actually reflect individuals' dietary intake has not been rigorously tested. This study examined cross-sectional agreement between estimates of diet quality and nutrient densities derived from objectively documented household food purchases and those derived from interviewer-administered 24-h diet recalls. A secondary aim was to identify moderator variables associated with attenuated agreement between purchases and dietary intake. Primary household food shoppers (N = 196) collected and annotated receipts for all household food and beverage purchases (16,356 total) over 14 days. Research staff visited participants' homes four times to photograph the packaging and nutrition labels of each purchased item. Three or four multiple-pass 24-h diet recalls were performed within the same 14-d period. Nutrient densities and Healthy Eating Index-2010 (HEI-2010) scores were calculated from both food purchase and diet recall data. HEI-2010 scores derived from food purchases (median = 60.9, interquartile range 49.1-71.7) showed moderate agreement (ρc = .57, p social desirability, household income, household size, and body mass. Concordance for individual nutrient densities from food purchases and 24-h diet recalls varied widely from ρc = .10 to .61, with the strongest associations observed for fiber (ρc = .61), whole fruit (ρc = .48), and vegetables (ρc = .39). Objectively documented household food purchases yield an unbiased and reasonably accurate estimate of overall diet quality as measured through 24-h diet recalls, but are generally less useful for characterizing dietary intake of specific nutrients. Thus, some degree of caution is warranted when interpreting food purchase data as a reflection of diet in

    Because the association between soy consumption and gastric cancer is inconsistent, we evaluated the putative preventive effect of soy food on gastric cancer risk in the Shanghai Women's and Men's Health Studies, comprising a total of 128,687 participants. Intake of nonfermented soy foods was estimated using 2 validated food-frequency questionnaires. HRs were calculated with 95% CIs for intake amounts of total nonfermented soy food intake, soy protein, and isoflavones as well as individual soy food groups using Cox proportional hazards regression. A total of 493 distal gastric cancer cases were identified by 2010. Although all risk estimates for summary measures of soy food intake above the lowest quartile (quartile 1) were suggestive of a protective effect, no statistically significant associations with risk of distal gastric cancer were found. Among the separate soy food groups, significant reductions in risk of distal gastric cancer by increasing intake of tofu were found in men in quartile 2 (HR: 0.59; 95% CI: 0.40, 0.86), quartile 3 (HR: 0.62; 95% CI: 0.44, 0.88), and quartile 4 (HR: 0.64; 95% CI: 0.42, 0.99), resulting in a significant trend (P-trend = 0.02). Dry bean intake was also inversely associated with decreased risk of gastric cancer, but in postmenopausal women only [quartile 2 (HR: 0.54; 95% CI: 0.30, 0.96); quartile 3 (HR: 0.90; 95% CI: 0.64, 1.27); and quartile 4 (HR: 0.63; 95% CI: 0.43, 0.91)], resulting in a significant trend (P-trend = 0.03). Overall, our study found no statistically significant association between nonfermented soy food intake and distal gastric cancer risk, though the data supported the hypothesis that tofu may protect against distal gastric cancer in men and dry bean consumption may decrease the risk of gastric cancer in postmenopausal women.

    Full Text Available It is often assumed that social models influence people's eating behavior by providing a norm of appropriate food intake, but this hypothesis has not been directly tested. In three experiments, female participants were exposed to a low-intake model, a high-intake model, or no model (control condition. Experiments 1 and 2 used a remote-confederate manipulation and were conducted in the context of a cookie taste test. Experiment 3 used a live confederate and was conducted in the context of a task during which participants were given incidental access to food. Participants also rated the extent to which their food intake was influenced by a variety of factors (e.g., hunger, taste, how much others ate. In all three experiments, participants in the low-intake conditions ate less than did participants in the high-intake conditions, and also reported a lower perceived norm of appropriate intake. Furthermore, perceived norms of appropriate intake mediated the effects of the social model on participants' food intake. Despite the observed effects of the social models, participants were much more likely to indicate that their food intake was influenced by taste and hunger than by the behavior of the social models. Thus, social models appear to influence food intake by providing a norm of appropriate eating behavior, but people may be unaware of the influence of a social model on their behavior.

    Full Text Available The collection of accurate dietary intakes using traditional dietary assessment methods (e.g., food records from military personnel is challenging due to the demanding physiological and psychological conditions of training or operations. In addition, these methods are burdensome, time consuming, and prone to measurement errors. Adopting smart-phone/tablet technology could overcome some of these barriers. The objective was to assess the validity of a tablet app, modified to contain detailed nutritional composition data, in comparison to a measured food intake/waste method. A sample of Canadian Armed Forces personnel, randomized to either a tablet app (n = 9 or a weighed food record (wFR (n = 9, recorded the consumption of standard military rations for a total of 8 days. Compared to the gold standard measured food intake/waste method, the difference in mean energy intake was small (−73 kcal/day for tablet app and −108 kcal/day for wFR (p > 0.05. Repeated Measures Bland-Altman plots indicated good agreement for both methods (tablet app and wFR with the measured food intake/waste method. These findings demonstrate that the tablet app, with added nutritional composition data, is comparable to the traditional dietary assessment method (wFR and performs satisfactorily in relation to the measured food intake/waste method to assess energy, macronutrient, and selected micronutrient intakes in a sample of military personnel.

    Full Text Available Abstract Background In an epidemiological study, it is essential to test the validity of the food frequency questionnaire (FFQ for its ability to estimate dietary intake. The objectives of our study were to 1 validate a FFQ for estimating folate intake, and to identify the foods that contribute to inter-individual variation of folate intake in the Japanese population. Methods Validity of the FFQ was evaluated using 28-day weighed dietary records (DRs as gold standard in the two groups independently. In the group for which the FFQ was developed, validity was evaluated by Spearman's correlation coefficients (CCs, and linear regression analysis was used to identify foods with large inter-individual variation. The cumulative mean intake of these foods was compared with total intake estimated by the DR. The external validity of the FFQ and intake from foods on the same list were evaluated in the other group to verify generalizability. Subjects were a subsample from the Japan Public Health Center-based prospective Study who volunteered to participate in the FFQ validation study. Results CCs for the internal validity of the FFQ were 0.49 for men and 0.29 and women, while CCs for external validity were 0.33 for men and 0.42 for women. CCs for cumulative folate intake from 33 foods selected by regression analysis were also applicable to an external population. Conclusion Our FFQ was valid for and generalizable to the estimation of folate intake. Foods identified as predictors of inter-individual variation in folate intake were also generalizable in Japanese populations. The FFQ with 138 foods was valid for the estimation of folate intake, while that with 33 foods might be useful for estimating inter-individual variation and ranking of individual folate intake.

    Full Text Available Background. Saudi women depend on food sources to maintain their serum 25(OH D concentrations because covering by traditional clothing and time spent indoors limit their sun exposure. Little is known about vitamin D intake and its main food sources in Saudi Arabia. In addition, the association between vitamin D and calcium intake and bone mineral density (BMD in young women is not well researched. Objectives. To assess the adequacy of vitamin D intake among Saudi women as compared to the estimated average requirements (EARs, to identify dietary vitamin D sources, to examine potential determinants of vitamin D intake, and to assess bone health and the association of calcium and vitamin D intake with BMD. Methods. This cross-sectional study was conducted in 257 premenopausal women aged 20–50 years in Jeddah, Saudi Arabia. Dietary vitamin D and calcium were assessed by the Semiquantitative Food Frequency Questionnaire. BMD was measured using dual-energy X-ray absorptiometry (DXA in a subset of women n=102 at the lumbar spine and femur neck. Results. Sixty-five percent of women were below the EAR for vitamin D, and 61% fell below the EAR for calcium. Dairy products, supplements, and fish contributed most to vitamin D intake. Increased age was an independent determinant of sufficient vitamin D intake p<0.001. The prevalence of osteopenia was 33% in the lumbar spine and 30% in the femur neck. There was a significant positive association between calcium intake and BMD at the lumbar spine p=0.043 after controlling for body mass index and energy intake. Vitamin D intake was not significantly different between women with low and normal bone mass. Conclusion. Premenopausal women in Jeddah have insufficient vitamin D and calcium intakes. Public health strategies to improve nutrition in young women are needed, and expanding fortification programs to include all dairy products would be useful.

    The hypothalamic melanocortin system—the melanocortin receptor of type 4 (MC4R) and its ligands: α-melanin-stimulating hormone (α-MSH, agonist, inducing hypophagia), and agouti-related protein (AgRP, antagonist, inducing hyperphagia)—is considered to play a central role in the control of food intake. We tested its implication in the mediation of the hunger-curbing effects of protein-enriched diets (PED) in mice. Whereas there was a 20% decrease in food intake in mice fed on the PED, compared to mice fed on an isocaloric starch-enriched diet, there was a paradoxical decrease in expression of the hypothalamic proopiomelanocortin gene, precursor of α-MSH, and increase in expression of the gene encoding AgRP. The hypophagia effect of PED took place in mice with invalidation of either MC4R or POMC, and was even strengthened in mice with ablation of the AgRP-expressing neurons. These data strongly suggest that the hypothalamic melanocortin system does not mediate the hunger-curbing effects induced by changes in the macronutrient composition of food. Rather, the role of this system might be to defend the body against the variations in food intake generated by the nutritional environment. PMID:21544212

    Advances in nutritional assessment are continuing to embrace developments in computer technology. The online Food4Me food frequency questionnaire (FFQ) was created as an electronic system for the collection of nutrient intake data. To ensure its accuracy in assessing both nutrient and food group intake, further validation against data obtained using a reliable, but independent, instrument and assessment of its reproducibility are required. The aim was to assess the reproducibility and validity of the Food4Me FFQ against a 4-day weighed food record (WFR). Reproducibility of the Food4Me FFQ was assessed using test-retest methodology by asking participants to complete the FFQ on 2 occasions 4 weeks apart. To assess the validity of the Food4Me FFQ against the 4-day WFR, half the participants were also asked to complete a 4-day WFR 1 week after the first administration of the Food4Me FFQ. Level of agreement between nutrient and food group intakes estimated by the repeated Food4Me FFQ and the Food4Me FFQ and 4-day WFR were evaluated using Bland-Altman methodology and classification into quartiles of daily intake. Crude unadjusted correlation coefficients were also calculated for nutrient and food group intakes. In total, 100 people participated in the assessment of reproducibility (mean age 32, SD 12 years), and 49 of these (mean age 27, SD 8 years) also took part in the assessment of validity. Crude unadjusted correlations for repeated Food4Me FFQ ranged from .65 (vitamin D) to .90 (alcohol). The mean cross-classification into "exact agreement plus adjacent" was 92% for both nutrient and food group intakes, and Bland-Altman plots showed good agreement for energy-adjusted macronutrient intakes. Agreement between the Food4Me FFQ and 4-day WFR varied, with crude unadjusted correlations ranging from .23 (vitamin D) to .65 (protein, % total energy) for nutrient intakes and .11 (soups, sauces and miscellaneous foods) to .73 (yogurts) for food group intake.

    Excessive dietary sodium intake increases blood pressure and cardiovascular risk. In Western diets, the majority of dietary sodium comes from packaged and prepared foods (≈75%); however, in Mexico there is no available data on the main food sources of dietary sodium. The main objective of this study was to identify and characterize the major food sources of dietary sodium in a sample of the Mexican Salt and Mexico (SALMEX) cohort. Adult male and female participants of the SALMEX study who provided a complete and valid three-day food record during the baseline visit were included. Overall, 950 participants (mean age 38.6 ± 10.7 years) were analyzed to determine the total sodium contributed by the main food sources of sodium identified. Mean daily sodium intake estimated by three-day food records and 24-h urinary sodium excretion was 2647.2 ± 976.9 mg/day and 3497.2 ± 1393.0, in the overall population, respectively. Processed meat was the main contributor to daily sodium intake, representing 8% of total sodium intake per capita as measured by three-day food records. When savory bread (8%) and sweet bakery goods (8%) were considered together as bread products, these were the major contributor to daily sodium intake, accounting for the 16% of total sodium intake, followed by processed meat (8%), natural cheeses (5%), and tacos (5%). These results highlight the need for public health policies focused on reducing the sodium content of processed food in Mexico. PMID:28749449

    Full Text Available Abstract Background The need to promote a healthy diet to curb the current obesity epidemic has today been recognized by most countries. A prerequisite for planning and evaluating interventions on dietary intake is the existence of valid information on long-term average dietary intake in a population. Few large, population-based studies of dietary intake have been carried out in Sweden. The largest to date is the Västerbotten Intervention Program (VIP, which was initiated in 1985, with data collection still ongoing. This paper reports on the first comprehensive analyses of the dietary data and presents dietary intake patterns among over 60,000 women and men in northern Sweden during 1992–2005. Methods Between 1992 and 2005, 71,367 inhabitants in Västerbotten county aged 30, 40, 50, and 60 years visited their local health care center as part of the VIP. Participants of VIP filled in an 84- or 64-item food frequency questionnaire (FFQ and provided sociodemographic information. Complete and realistic information on consumption frequency was provided by 62,531 individuals. Food intake patterns were analyzed using K-means cluster analyses. Results The mean daily energy intake was 6,83 (± 1,77 MJ among women and 8,71 (± 2,26 MJ among men. More than half of both women and men were classified as Low Energy Reporters (defined as individuals reporting a food intake level below the lower 95% confidence interval limit of the physical activity level. Larger variation in frequency of daily intake was seen among women than among men for most food groups. Among women, four dietary clusters were identified, labeled "Fruit and vegetables", "High fat", "Coffee and sandwich", and "Tea and ice cream". Among men, three dietary clusters were identified, labeled "Fruit and vegetables", "High fat", and "Tea, soda and cookies". Conclusion More distinct food intake patterns were seen among women than men in this study in northern Sweden. Due to large proportions of

    Stress affects body weight and food intake, but the underlying mechanisms are not well understood. We evaluated the changes in body weight and food intake of ICR male mice subjected to daily 2 hours restraint stress for 15 days. Hypothalamic gene expression profiling was analyzed by cDNA microarray. Daily body weight and food intake measurements revealed that both parameters decreased rapidly after initiating daily restraint stress. Body weights of stressed mice then remained significantly lower than the control body weights, even though food intake slowly recovered to 90% of the control intake at the end of the experiment. cDNA microarray analysis revealed that chronic restraint stress affects the expression of hypothalamic genes possibly related to body weight control. Since decreases of daily food intake and body weight were remarkable in days 1 to 4 of restraint, we examined the expression of food intake-related genes in the hypothalamus. During these periods, the expressions of ghrelin and pro-opiomelanocortin mRNA were significantly changed in mice undergoing restraint stress. Moreover, daily serum corticosterone levels gradually increased, while leptin levels significantly decreased. The present study demonstrates that restraint stress affects body weight and food intake by initially modifying canonical food intake-related genes and then later modifying other genes involved in energy metabolism. These genetic changes appear to be mediated, at least in part, by corticosterone.

    Automation of dietary assessment can reduce limitations of established methodologies, by alleviating participant and researcher burden. Designed as a research tool, the electronic Dietary Intake Assessment (e-DIA) is a food record in mobile phone application format. The present study aimed to examine the relative validity of the e-DIA with the 24-h recall method to estimate intake of food groups. A sample of eighty university students aged 19-24 years recorded 5 d of e-DIA and 3 d of recall within this 5-d period. The three matching days of dietary data were used for analysis. Food intake data were disaggregated and apportioned to one of eight food groups. Median intakes of food groups were similar between the methods, and strong correlations were found (mean: 0·79, range: 0·69-0·88). Cross-classification by tertiles produced a high level of exact agreement (mean: 71 %, range: 65-75 %), and weighted κ values were moderate to good (range: 0·54-0·71). Although mean differences (e-DIA-recall) were small (range: -13 to 23 g), limits of agreement (LOA) were relatively large (e.g. for vegetables, mean difference: -4 g, LOA: -159 to 151 g). The Bland-Altman plots showed robust agreement, with minimum bias. This analysis supports the use of e-DIA as an alternative to the repeated 24-h recall method for ranking individuals' food group intake.

    To find out how the consumption of organic food during pregnancy is associated with consumer characteristics, dietary patterns and macro- and micronutrient intakes. Cross-sectional description of consumer characteristics, dietary patterns and macro- and micronutrient intakes associated with consumption of organic food during pregnancy. Healthy, pregnant women recruited to a prospective cohort study at midwives' practices in the southern part of the Netherlands; to enrich the study with participants adhering to alternative lifestyles, pregnant women were recruited through various specific channels. Participants who filled in questionnaires on food frequency in gestational week 34 (n 2786). Participant groups were defined based on the share of organic products within various food types. Consumers of organic food more often adhere to specific lifestyle rules, such as vegetarianism or anthroposophy, than do participants who consume conventional food only (reference group). Consumption of organic food is associated with food patterns comprising more products of vegetable origin (soya/vegetarian products, vegetables, cereal products, bread, fruits, and legumes) and fewer animal products (milk and meat), sugar and potatoes than consumed in conventional diets. These differences translate into distinct intakes of macro- and micronutrients, including higher retinol, carotene, tocopherol and folate intakes, lower intakes of vitamin D and B12 and specific types of trans-fatty acids in the organic groups. These differences are seen even in groups with low consumption of organic food. Various consumer characteristics, specific dietary patterns and types of food intake are associated with the consumption of organic food during pregnancy.

    Avoidant/restrictive food intake disorder (ARFID) is a new diagnostic category in DSM-5. Although replacing Feeding Disorder of Infancy or Early Childhood, it is not restricted to childhood presentations. In keeping with the broader aim of revising and updating criteria and text to better reflect lifespan issues and clinical expression across the age range, ARFID is a diagnosis relevant to children, adolescents, and adults. This case example of a 13-year old boy with ARFID illustrates key issues in diagnosis and treatment planning. The issues discussed are not exhaustive, but serve as a guide for central diagnostic and treatment issues to be considered by the clinician. It is anticipated that the inclusion of specific criteria for ARFID as a category within Feeding and Eating Disorders in DSM-5 will stimulate research into its typology, prevalence, and incidence in different populations and facilitate the development of effective, evidence-based interventions for this patient group.

This study estimates the impact of recent reformulations in the task force food groups by estimating changes in median intake of TFA and SFA in Dutch young adults. This is a modelling study with food consumption data of young adults. Intakes were estimated before reformulation using food composition data of 2001 as a reference and while including most recent fatty acid composition of foods for task force food groups. Food composition of other foods and food consumption was assumed unchanged. Average TFA intake significantly decreased from 1.0 E% in the reference to 0.8 E% in the reformulation scenario. Pastry, cakes and biscuits, and snacks contributed most to the decrease of TFA. Estimated SFA intake did not change. When solid baking and spreading fats were additionally replaced with fluid ones, SFA intake decreases from 12.9 E% to 12.1 E%. Fatty acid reformulation in the task force food groups contributed to reductions in TFA intake. For further reductions in SFA intake a different food choice is primordial.

    Exclusion diets for the management of food allergy pose a risk of nutritional deficiencies and inadequate growth in children, yet less is known about their effect in adolescents and adults. The present study aimed to compare the dietary intake of adolescents and adults with food allergies with that of a control group. A food allergic and a control group were recruited from Portsmouth and the Isle of Wight in the UK. Participants were recruited from a food allergy charity, allergy clinics, a local school and university, and previous research studies. Macro and micronutrient intake data were obtained using a 4-day estimated food diary. Sociodemographic and anthropometric data was collected via a constructed questionnaire. This cross-sectional study included 81 adolescents (48 food allergic and 33 controls) aged 11-18 years and 70 adults aged 19-65 years (23 food allergic and 47 controls). Overall, 19 (22.8%) adolescents and 19 (27.1%) adults took dietary supplements, with no difference according to food allergic status. Adolescents with food allergy had higher intakes of niacin and selenium than adolescents without (P food allergies had higher intakes of folate and zinc than those without (P food allergic status. The dietary intake of food allergic participants was broadly similar and, in some cases, better than that of control participants. However, suboptimal intakes of several micronutrients were observed across all participants, suggesting poor food choices. © 2017 The British Dietetic Association Ltd.

    To examine longitudinal associations of parental report of household food availability and parent intakes of fruits, vegetables and dairy foods with adolescent intakes of the same foods. This study expands upon the limited research of longitudinal studies examining the role of parents and household food availability in adolescent dietary intakes. Longitudinal study. Project EAT-II followed an ethnically and socio-economically diverse sample of adolescents from 1999 (time 1) to 2004 (time 2). In addition to the Project EAT survey, adolescents completed the Youth Adolescent Food-Frequency Questionnaire in both time periods, and parents of adolescents completed a telephone survey at time 1. General linear modelling was used to examine the relationship between parent intake and home availability and adolescent intake, adjusting for time 1 adolescent intakes. Associations were examined separately for the high school and young adult cohorts and separately for males and females in combined cohorts. The sample included 509 pairs of parents/guardians and adolescents. Vegetables served at dinner significantly predicted adolescent intakes of vegetables for males (P = 0.037), females (P = 0.009), high school (P = 0.033) and young adults (P = 0.05) at 5-year follow-up. Among young adults, serving milk at dinner predicted dairy intake (P = 0.002). Time 1 parental intakes significantly predicted intakes of young adults for fruit (P = 0.044), vegetables (P = 0.041) and dairy foods (P = 0.008). Parental intake predicted intake of dairy for females (P = 0.02). The findings suggest the importance of providing parents of adolescents with knowledge and skills to enhance the home food environment and improve their own eating behaviours.

    A well-designed, validated quantitative food frequency questionnaire (FFQ) could offer an efficient and cost-effective method for assessing habitual vitamin D intake. The present study aimed to describe the development, validation and implementation of a vitamin D FFQ. National food consumption survey data obtained from Irish adults (18-64 years) were used to identify foods that contribute 95% of vitamin D intake. A winter-based validation study was carried out for the resulting FFQ in 120 females, including 98 women [mean (SD) 65.0 (7.3) years] and 22 girls [12.2 (0.8) years], using a 14-day diet history (DH) as a comparator. Serum 25(OH)D concentrations were analysed. Validity coefficients were calculated using the method of triads. Cross-classification and Bland-Altman analysis were also performed. Median (interquartile range) vitamin D intakes (including the contribution from nutritional supplements) were 5.4 (3.7) and 3.7 (5.9) μg day(-1) from the FFQ and DH, respectively and intakes of vitamin D from food sources were 3.6 (3.1) and 2.4 (2.2) μg day(-1) . The FFQ and DH classified 86% and 87% of individuals into the same and adjacent thirds of wintertime serum 25(OH)D status, respectively. There was a strong association (r = 0.71, P < 0.0001) and no significant systematic or proportional bias observed for the difference between estimates from the FFQ and DH. The validity coefficient for the FFQ was 0.92 (95% confidence interval = 0.80-0.97). Repeatability analysis (n = 56) performed 6-12 months later showed no significant difference in estimates of vitamin D between administrations. The data obtained in the present study indicate high validity and good reproducibility of a short, interviewer-administered FFQ for vitamin D. © 2016 The British Dietetic Association Ltd.

    Motilin-induced phase III contractions have been identified as a hunger signal. These phase III contractions occur as part of the migrating motor complex (MMC), a contractility pattern of the gastrointestinal tract during fasting. The mechanism involved in this association between subjective hunger feelings and gastrointestinal motility during the MMC is largely unknown, however, as is its ability to stimulate food intake. We sought to 1) investigate the occurrence of hunger peaks and their relation to phase III contractions, 2) evaluate whether this relation was cholinergically driven, and 3) assess the ability of the motilin receptor agonist erythromycin to induce food intake. An algorithm was developed to detect hunger peaks. The association with phase III contractions was studied in 14 healthy volunteers [50% men; mean ± SEM age: 25 ± 2 y; mean ± SEM body mass index (BMI; in kg/m(2)): 23 ± 1]. The impact of pharmacologically induced phase III contractions on the occurrence of hunger peaks and the involvement of a cholinergic pathway were assessed in 14 healthy volunteers (43% men; age: 29 ± 3 y; BMI: 23 ± 1). Last, the effect of erythromycin administration on food intake was examined in 15 healthy volunteers (40% men; age: 28 ± 3 y; BMI: 22 ± 1). The occurrence of hunger peaks and their significant association with phase III contractions was confirmed (P hunger peaks (P hunger feelings through a cholinergic pathway. Moreover, erythromycin stimulated food intake, suggesting a physiologic role of motilin as an orexigenic signal from the gastrointestinal tract.

    Food composition databases are essential for estimating nutrient intakes in food consumption surveys. The present study aimed to evaluate the Mali food composition database (TACAM) for assessing intakes of energy and selected nutrients at population level. Weighed food records and duplicate portions of all foods consumed during one day were collected. Intakes of energy, protein, fat, available carbohydrates, dietary fibre, Ca, Fe, Zn and vitamin A were assessed by: (i) estimating the nutrient intake from weighed food records based on an adjusted TACAM (a-TACAM); and (ii) chemical analysis of the duplicate portions. Agreement between the two methods was determined using the Wilcoxon signed-rank test and Bland-Altman plots. Bamako, Mali. Apparently healthy non-pregnant, non-lactating women (n 36) aged 15-36 years. Correlation coefficients between estimated and analysed values ranged from 0·38 to 0·61. At population level, mean estimated and analysed nutrient intakes differed significantly for carbohydrates (203·0 v. 243·5 g/d), Fe (9·9 v. 22·8 mg/d) and vitamin A (356 v. 246 µg retinol activity equivalents). At individual level, all estimated and analysed nutrient intakes differed significantly; the differences tended to increase with higher intakes. The a-TACAM is sufficiently acceptable for measuring average intakes of macronutrients, Ca and Zn at population level in low-intake populations, but not for carbohydrate, vitamin A and Fe intakes, and nutrient densities.

    Central oxytocin (OT) promotes feeding termination in response to homeostatic challenges, such as excessive stomach distension, salt loading and toxicity. OT has also been proposed to affect feeding reward by decreasing the consumption of palatable carbohydrates and sweet tastants. Because the OT receptor (OTR) is expressed in the nucleus accumbens core (AcbC) and shell (AcbSh), a site regulating diverse aspects of eating behaviour, we investigated whether OT acts there to affect appetite in rats. First, we examined whether direct AcbC and AcbSh OT injections affect hunger- and palatability-driven consumption. We found that only AcbC OT infusions decrease deprivation-induced chow intake and reduce the consumption of palatable sucrose and saccharin solutions in nondeprived animals. These effects were abolished by pretreatment with an OTR antagonist, L-368,899, injected in the same site. AcbC OT at an anorexigenic dose did not induce a conditioned taste aversion, which indicates that AcbC OT-driven anorexia is not caused by sickness/malaise. The appetite-specific effect of AcbC OT is supported by the real-time polymerase chain reaction analysis of OTR mRNA in the AcbC, which revealed that food deprivation elevates OTR mRNA expression, whereas saccharin solution intake decreases OTR transcript levels. We also used c-Fos immunohistochemistry as a marker of neuronal activation and found that AcbC OT injection increases activation of the AcbC itself, as well as of two feeding-related sites: the hypothalamic paraventricular and supraoptic nuclei. Finally, considering the fact that OT plays a significant role in social behaviour, we examined whether offering animals a meal in a social setting would modify their hypophagic response to AcbC OT injections. We found that a social context abolishes the anorexigenic effects of AcbC OT. We conclude that OT acting via the AcbC decreases food intake driven by hunger and reward in rats offered a meal in a nonsocial setting. © 2016

    Previous studies have shown that individuals with circadian preferences for the evening (wake up later and reach maximum activity in the afternoon) have distorted dietary habits and misregulated body weight. Therefore, the present study was conducted to analyse the possible relationships between 'morningness' or 'eveningness' (chronotype), dietary habits and the level of obesity. Among 400 participants, 171 subjects finished the follow-up period and were evaluated. Anthropometric, clinical and dietary parameters were analysed; the Horne-Östberg test was used to determine chronotype. A hypocaloric-behavioural intervention was performed in the overweight/obese subjects. In normal-weight subjects, the morningness group ingested most of their energy and nutrients at breakfast and lunch, whereas the eveningness group showed a higher intake at dinner, corresponding with their chronotypes. A significant interaction was revealed between chronotype and body mass index regarding the energy and nutrients consumed at dinner (Pfood intake was higher in the eveningness group, but in the overweight subjects the situation was inverse. In addition, the food preferences were related to the chronotype, as the morningness subjects showed a higher intake of fruit (Pfood intake corresponded to the chronotype in the normal-weight subjects; however, the overweight/obese subjects showed intake patterns removed from their physiological rhythms. These findings may indicate a need to design specific diets based not only on the total energy expenditure but also on the chronotype, as an indicator of the biological rhythms.

    Semi-quantitative Food Frequency Questionnaires (FFQs) analyze average food and nutrient intake over extended periods to associate habitual dietary intake with health problems and chronic diseases. A tool of this nature applicable to both women and men is not presently available in Mexico. To validate a FFQ for adult men and women. The study was conducted on 97 participants, 61% were women. Two FFQs were administered (with a one-year interval) to measure reproducibility. To assess validity, the second FFQ was compared against dietary record (DR) covering nine days. Statistical analyses included Pearson correlations and Intraclass Correlation Coefficients (ICC). The de-attenuation of the ICC resulting from intraindividual variability was controlled. The validity analysis was complemented by comparing the classification ability of FFQ to that of DR through concordance between intake categories and Bland-Altman plots. Reproducibility: ICC values for food groups ranged 0.42-0.87; the range for energy and nutrients was between 0.34 and 0.82. ICC values for food groups ranged 0.35-0.84; the range for energy and nutrients was between 0.36 and 0.77. Most subjects (56.7-76.3%) classified in the same or adjacent quintile for energy and nutrients using both methods. Extreme misclassification was <6.3% for all items. Bland-Altman plots reveal high concordance between FFQ and DR. FFQ produced sufficient levels of reproducibility and validity to determine average daily intake over one year. These results will enable the analysis of possible associations with chronic diseases and dietary diagnoses in adult populations of men and women. Copyright AULA MEDICA EDICIONES 2013.

    Full Text Available Emergency food pantries provide food at no cost to low-resource populations. The purpose of this study was to evaluate single-day dietary intake patterns before and after visiting a food pantry among food-secure and food-insecure pantry clients. This observational cohort study comprised a paired, before-and-after design with a pantry visit as the intervention. Participants (n = 455 completed a demographic and food security assessment, and two 24-h dietary recalls. Adult food security was measured using the U.S. Household Food Security Survey Module. Dietary intake patterns were assessed using Automated Self-Administered 24-h Recall data and classified by Healthy Eating Index (HEI-2010 scores, dietary variety, number of eating occasions, and energy intake. Paired t-tests and Wilcoxon signed-rank tests compared outcomes before and after a pantry visit. Mean dietary variety increased after the pantry visit among both food-secure (p = 0.02 and food-insecure (p < 0.0001 pantry clients. Mean energy intake (p = 0.0003, number of eating occasions (p = 0.004, and HEI-2010 component scores for total fruit (p < 0.001 and whole fruit (p < 0.0003 increased among food-insecure pantry clients only. A pantry visit may improve dietary intake patterns, especially among food-insecure pantry clients.

    Few studies have examined direct effects of food cues presented within television (TV) programs on eating behavior in adults. This research experimentally determined whether exposure to food cues in TV programs affects energy intake during TV viewing among young women, independently from food cues presented in TV advertisements. The experiment involved a 2 (TV program with or without food cues) by 2 (TV advertisements with or without food cues) between-participants design. While watching TV, participants could freely eat peanut chocolate candies and crisps (potato chips). Participants were 121 young women (mean age = 19.6 years; mean BMI = 22.5). Participants who watched a TV program with food cues tended to have a lower total energy intake and ate significantly less peanut chocolate candies than participants who watched the same TV program without food cues. This effect was particularly pronounced among participants with a higher BMI. Food advertisements did not affect energy intake. Findings may indicate that subtle continuous food cues during TV programs could make young females more aware of their own eating and/or weight, leading to reduced intake of particularly sweet snack foods during TV viewing. Considering the non-significant trend for the effect of the TV program with food cues on total energy intake, findings should be replicated to provide possible tools for prevention campaigns using food cue reminders to watch one's intake.

    This review describes the state-of-the-art for dietary assessment using smartphone apps and digital technology and provides an update on the efficacy of technology-mediated interventions for dietary change. Technology has progressed from apps requiring entry of foods consumed, to digital imaging to provide food intake data. However, these methods rely on patients being active in data collection. The automated estimation of the volume and composition of every meal consumed globally is years away. The use of text messaging, apps, social media, and combinations of these for interventions is growing and proving effective for type 2 diabetes mellitus (T2DM). Effectiveness of text messaging for obesity management is improving and multicomponent interventions show promise. A stand-alone app is less likely to produce positive outcomes and social media is relatively unexplored. A concentrated effort will be needed to progress digital dietary assessment. Researcher-designed technology programs are producing positive outcomes for T2DM but further research is needed in the area of weight management.

    Food intake depends on homeostatic and non-homeostatic factors. In order to use grape seed proanthocyanidins (GSPE) as food intake limiting agents, it is important to define the key characteristics of their bioactivity within this complex function. We treated rats with acute and chronic treatments of GSPE at different doses to identify the importance of eating patterns and GSPE dose and the mechanistic aspects of GSPE. GSPE-induced food intake inhibition must be reproduced under non-stressful conditions and with a stable and synchronized feeding pattern. A minimum dose of around 350 mg GSPE/kg body weight (BW) is needed. GSPE components act by activating the Glucagon-like peptide-1 (GLP-1) receptor because their effect is blocked by Exendin 9-39. GSPE in turn acts on the hypothalamic center of food intake control probably because of increased GLP-1 production in the intestine. To conclude, GSPE inhibits food intake through GLP-1 signaling, but it needs to be dosed under optimal conditions to exert this effect.

Higher serum PTH concentrations have been shown in those who consume foods with phosphorus additives. These fi...

    Several authors showed that providing choice may increase food liking and food intake. However, the impact of choice may be modulated by assortment's characteristics, such as the number of alternatives or their dissimilarity. The present study compared the impact of choice on food liking and intake under the two following conditions: (1) when choosing a product to consume from among similar products versus dissimilar products; and (2) when choosing a product to consume from among pleasant products versus unpleasant products. Two experiments were carried out using the same design: the "apple puree" experiment (n = 80), where the volunteers choose from among similar products (apple purees varying in texture) and the "dessert" experiment (n = 80), where the volunteers choose from among dissimilar products (fruit dessert, dairy dessert, custard, pudding). During the first session, participants rated their liking for 12 products (apples purees or desserts). Then the participants were divided into a "pleasant" group (n = 40) in which volunteers were assigned three pleasant products, and an "unpleasant" group (n = 40) in which volunteers were assigned three unpleasant products. Finally, all of the volunteers participated in a choice session - volunteers were presented with their three assigned products and asked to choose one of the products, and a no-choice session - volunteers were served with one product that was randomly selected from among their three assigned products. Providing choice led to an increase in food liking in both experiments and an increase in food intake only for the desserts, namely only when the volunteers chose the product to consume from among "not too similar" alternatives. No effect of assortment's pleasantness was observed. Copyright © 2015 Elsevier Ltd. All rights reserved.

  9. vProtein: identifying optimal amino acid complements from plant-based foods.

    Directory of Open Access Journals (Sweden)

    Peter J Woolf

    Full Text Available BACKGROUND: Indispensible amino acids (IAAs are used by the body in different proportions. Most animal-based foods provide these IAAs in roughly the needed proportions, but many plant-based foods provide different proportions of IAAs. To explore how these plant-based foods can be better used in human nutrition, we have created the computational tool vProtein to identify optimal food complements to satisfy human protein needs. METHODS: vProtein uses 1251 plant-based foods listed in the United States Department of Agriculture standard release 22 database to determine the quantity of each food or pair of foods required to satisfy human IAA needs as determined by the 2005 daily recommended intake. The quantity of food in a pair is found using a linear programming approach that minimizes total calories, total excess IAAs, or the total weight of the combination. RESULTS: For single foods, vProtein identifies foods with particularly balanced IAA patterns such as wheat germ, quinoa, and cauliflower. vProtein also identifies foods with particularly unbalanced IAA patterns such as macadamia nuts, degermed corn products, and wakame seaweed. Although less useful alone, some unbalanced foods provide unusually good complements, such as Brazil nuts to legumes. Interestingly, vProtein finds no statistically significant bias toward grain/legume pairings for protein complementation. These analyses suggest that pairings of plant-based foods should be based on the individual foods themselves instead of based on broader food group-food group pairings. Overall, the most efficient pairings include sweet corn/tomatoes, apple/coconut, and sweet corn/cherry. The top pairings also highlight the utility of less common protein sources such as the seaweeds laver and spirulina, pumpkin leaves, and lambsquarters. From a public health perspective, many of the food pairings represent novel, low cost food sources to combat malnutrition. Full analysis results are available online

    This study examined the effects of intracerebroventricular injections of gamma-aminobutyric acid (GABA) agonists on short-term food intake in meat-type cockerels. In Experiment 1, birds were injected with various doses of muscimol, a GABA(A) agonist. In Experiment 2, the birds received bicuculline, a GABA(A) antagonist, prior to injection of muscimol. In Experiment 3, the effect of varying doses of baclofen, a GABA(B) agonist, on food intake was determined. The intracerebroventricular injection of muscimol caused a dose-dependent increase in food intake. This effect was significantly attenuated by pretreatment with bicuculline. Food intake was not affected by the intracerebroventricular injection of baclofen. These results suggest that GABA acts within the brain of broilers at a GABA(A), but not GABA(B), receptor to increase voluntary food intake.

    To examine how the food consumption from various food groups would impact American adults' sodium intake and whether this impact structurally changes over time, data were obtained from six-cycle National Health and Nutrition Examination Survey (NHANES) 1999-2010. Foods were categorized by the first two digits of the USDA food code. Regression models were employed to investigate the associations between the consumption of each food group and sodium intake, and whether there were changes in the associations in consecutive six cycles. Results show that the calorie consumption of oils, beverages and water, fruit juices, fruits, lamb, fruit products, and sugars and sweets had no significant impact on individuals' sodium intake, while calorie consumption of tomatoes, fish, dark-green vegetables, and crackers contributes the most to sodium intake. The contribution to sodium intake of most food groups does not change significantly over time, with the exception of salad dressing whose contribution to sodium intake increased in four consecutive years when compared to that of 1999-2000. The sodium amount contributed by one calorie consumption (sodium density) of most food was above the daily recommendation level, 1.2 mg per calorie per day. Lowering individuals' sodium intake involves either guiding individuals to consume more fruit related products or decreasing the amount of sodium in most food groups at the production or food preparation stages.

    Increasing water intake is often purported to reduce energy intake, and is recommended as a weight loss strategy. The few experimental studies that have been conducted to verify these claims have examined the impact of a single pre-load of water before a meal. Although correlational data indicate a relationship between hydration, energy intake, and weight status, there is very little experimental research in this area. The current studies examined the hypothesis that elevated hydration, through increased water intake, would suppress energy intake. In Experiment 1, participants (n = 49) were asked to consume either one, two, or three 500 ml bottles of water throughout the morning before a lunch buffet in the laboratory. When participants categorized as normal weight drank three bottles of water they consumed less energy at lunch, but there was no effect on participants categorized as overweight or obese. In addition, increased water intake suppressed liking of food items in all participants and hunger in females. A follow-up study (n = 45) was conducted to test if four bottles of water throughout the morning would result in a similar energy suppression in participants categorized as overweight or obese. Surprisingly, in the second experiment, there was no effect of water intake on energy intake at lunch in any of the conditions. There was, however, a similar suppression of hunger and food liking. In conclusion, increasing water intake throughout the morning only suppressed energy intake in individuals categorized as normal weight under certain circumstances, and had no effect on individuals categorized as overweight/obese.

    This study examined contributions of environmental and personal factors (specifically, food availability and expense, daily hassles, self-efficacy, positive and negative affect) to within-person and between-person variations in snack food intake in 100 African American women. Participants were signaled at random five times daily for seven days to complete a survey on a study-provided smartphone. Women reported consuming snack foods at 35.2% of signals. Easier food availability accounting for one's usual level was associated with higher snack food intake. Being near outlets that predominately sell snacks (e.g., convenience stores), while accounting for one's usual proximity to them, was associated with higher snack food intake. Accounting for one's usual daily hassle level, we found that on days with more frequent daily hassles snack food intake was higher. The positive association between within-person daily hassles frequency and snack food intake was stronger when foods were easily available. Public and private policies to curb ubiquitous food availability and mobile health interventions that take into account time-varying influences on food choices and provide real-time assistance in dealing with easy food availability and coping with stressors may be beneficial in improving African American women's day to day food choices.

    Background : Scientifically valid descriptions of dietary intake at population level are crucial for investigating diet effects on health and disease. Food frequency questionnaires (FFQs) are the most common dietary tools used in large epidemiological studies. Objective : To examine the relative validity of a newly developed FFQ to be used as dietary assessment tool in epidemiological studies. Design : Validity was evaluated by comparing the FFQ and a 4-day weighed food record (4-d FR) at nutrient and food group levels, Spearman's correlations, Bland-Altman analysis and Wilcoxon rank sum tests were used. Fifty-six participants completed a paper format FFQ and a 4-d FR within 4 weeks. Results : Corrected correlations between the two instruments ranged from 0.27 (carbohydrates) to 0.55 (protein), and at food group level from 0.09 (soup) to 0.92 (alcohol). Nine out of 25 food groups showed correlations > 0.5, indicating moderate validity. More than half the food groups were overestimated in the FFQ, especially vegetables (82.8%) and fruits (56.3%). Water, tea and coffee were underestimated (-14.0%). Conclusions : The FFQ showed moderate relative validity for protein and the food groups fruits, egg, meat, sausage, nuts, salty snacks and beverages. This study supports the use of the FFQ as an acceptable tool for assessing nutrition as a health determinant in large epidemiological studies.

    From both a clinical and research perspective, measuring food intake is an important issue in geriatric institutions. However, weighing food in this context can be complex, particularly when the items remaining on a plate (side dish, meat or fish and sauce) need to be weighed separately following consumption. A method based on photography that involves taking photographs after a meal to determine food intake consequently seems to be a good alternative. This method enables the storage of raw data so that unhurried analyses can be performed to distinguish the food items present in the images. Therefore, the aim of this paper was to validate a photographic method to measure food intake in terms of differentiating food item intake in the context of a geriatric institution. Sixty-six elderly residents took part in this study, which was performed in four French nursing homes. Four dishes of standardized portions were offered to the residents during 16 different lunchtimes. Three non-trained assessors then independently estimated both the total and specific food item intakes of the participants using images of their plates taken after the meal (photographic method) and a reference image of one plate taken before the meal. Total food intakes were also recorded by weighing the food. To test the reliability of the photographic method, agreements between different assessors and agreements among various estimates made by the same assessor were evaluated. To test the accuracy and specificity of this method, food intake estimates for the four dishes were compared with the food intakes determined using the weighed food method. To illustrate the added value of the photographic method, food consumption differences between the dishes were explained by investigating the intakes of specific food items. Although they were not specifically trained for this purpose, the results demonstrated that the assessor estimates agreed between assessors and among various estimates made by the same

    The aim of this study was to examine food patterns of Australian children ages 9 to 13 y in relation to ω-3 long-chain polyunsaturated fatty acid (ω-3 LCPUFA) intake. Secondary analysis was conducted on nationally representative food data of 1110 Australian children ages 9 to 13 y (525 boys and 585 girls) that was obtained using two 24-h recalls. Principle component factor analysis was used to identify food patterns. Discriminant function analysis was used to identify the relationship between the food patterns and total ω-3 LCPUFA intake. Four major food patterns emerged for each sex. For boys these were labeled: "snack foods," "soft drinks," "vegetables," and "pork and meat chops, steak, and mince." For girls they were labeled: "vegetables," "take-away," "tea, coffee, iced coffee drinks" and "canned meals and soup." Fish consumption bought from take-away outlets was more frequently consumed in the "soft drink" (r = 0.577) and take-away (r = 0.485) food pattern in boys and girls, respectively. In contrast, fish prepared at home was more often consumed in "vegetables" in both boys (r = 0.018) and girls (r = 0.106), as well as in the "pork and meat chops, steak and mince" food pattern in boys (r = 0.060). There was a trend that in boys, the "vegetables" group discriminated children who consumed ω-3 LCPUFA levels similar to adequate intakes (AI) (P = 0.067), whereas in girls, the take-away food pattern discriminated for being a fish consumer (P = 0.060). Dietary patterns associated with a high consumption of vegetables and "take-aways" food that include meat and fish are likely to positively influence dietary ω-3 LCPUFA intake in Australian children.

    Full Text Available Interventions are required to reduce children’s consumption of discretionary foods and drinks. To intervene we need to identify appropriate discretionary choice targets. This study aimed to determine the main discretionary choice contributors to energy and key nutrient intakes in children aged 2–18 years. Secondary analyses were performed with population weighted, single 24 h dietary recall data from the 2011–2012 National Nutrition and Physical Activity Survey. Cakes, muffins, and slices; sweet biscuits; potato crisps and similar snacks; and, processed meats and sugar-sweetened drinks were relatively commonly consumed and were within the top three to five contributors to per capita energy, saturated fat, sodium, and/or added sugars. Per consumer intake identified cereal-based takeaway foods; cakes, muffins and slices; meat pies and other savoury pastries; and, processed meats as top contributors to energy, saturated fat, and sodium across most age groups. Subgroups of sugar-sweetened drinks and cakes, muffins and slices were consistently key contributors to added sugars intake. This study identified optimal targets for interventions to reduce discretionary choices intake, likely to have the biggest impact on moderating energy intake while also reducing intakes of saturated fat, sodium and/or added sugars.

    Full Text Available Estimating polyphenol intake contributes to the understanding of polyphenols’ health benefits. However, information about human polyphenol intake is scarce, especially in the elderly. This study aimed to estimate the dietary intake and major sources of polyphenols and to determine whether there is any relationship between polyphenol intake and micronutrient intake in healthy elderly Japanese. First, 610 subjects (569 men, 41 women; aged 67.3 ± 6.1 years completed food frequency questionnaires. We then calculated their total polyphenol intake using our polyphenol content database. Their average total polyphenol intake was 1492 ± 665 mg/day, the greatest part of which was provided by beverages (79.1%. The daily polyphenol intake differed largely among individuals (183–4854 mg/day, also attributable mostly to beverage consumption. Coffee (43.2% and green tea (26.6% were the major sources of total polyphenol; the top 20 food items accounted for >90%. The polyphenol intake did not strongly correlate with the intake of any micronutrient, suggesting that polyphenols may exert health benefits independently of nutritional intake. The polyphenol intake in this elderly population was slightly higher than previous data in Japanese adults, and beverages such as coffee and green tea contributed highly to the intake.

    In clinical practice, dietary sodium assessment requires reliable and rapid screening tools. We wished to evaluate the usefulness of food frequency questionnaires (FFQ) in estimating dietary sodium intakes in haemodialysis patients. We used the Derby Salt Questionnaire (DSQ), and Scored Sodium Questionnaire (SSQ) to estimate sodium intake. Body composition was determined by bioimpedance. In total, 139 haemodialysis patients (95 men) completed the FFQs, with mean ± standard deviation age 67 ± 15 years. The mean FFQ scores were DSQ 3.5 ± 2.0 and SSQ 68.4 ± 24.5. Men had higher estimated dietary sodium intakes [DSQ median (range) 3.6 (0.6-10.1) versus female 2.2 (0.5-9.1), P = 0.007)]. Younger patients and those aged >75 years had the higher SSQ dietary sodium scores; 70.7 ± 27.8 and 76.8 ± 24.6 versus those aged 55-75 years, 61.8 ± 22.3, P = 0.04. Patients with greater estimated sodium intake had higher extracellular water (ECW) to intracellular water (ICW) ratios pre-dialysis [75.1 ±12.5 versus 67.7 ± 4.8, P sodium group (0.9 ± 13.7% versus 6.5 ± 14.1%, P = 0.04). Both questionnaires were acceptable to patients and identified higher estimated dietary sodium intake for men, those with greater ECW and, somewhat surprisingly, we found that older patients had a greater dietary sodium intake than expected. © The Author 2017.

    Bisphenol A (BPA) is a high-volume, synthetic compound found in epoxy resins and plastics used in food packaging. Food is believed to be a major source of BPA intake. In this study, we measured the concentration of BPA in convenience samplings of foodstuffs purchased in Dallas, Texas. Sampling entailed collection of 204 samples of fresh, frozen, and canned foods in two rounds in 2010. BPA was positive in 73% of the canned food samples, while it was found in only 7% of non-canned foods at low concentrations. The results of this food sampling program were used to calculate adult dietary intakes of BPA. A pathway approach combined food intakes, a "canned fraction" parameter which described what portion of total intake of that food came from canned products, and measured food concentrations. Dietary intakes were calculated as 12.6 ng/kg-day, of which 12.4 ng/kg-day was from canned foods. Canned vegetable intakes alone were 11.9 ng/kg-day. This dietary intake was compared to total intakes of BPA estimated from urine measurements of the National Health and Nutrition Examination Survey (NHANES). Total adult central tendency intakes ranged from 30 to 70 ng/kg-day for NHANES cycles between 2005 and 2010. Three possibilities were explored to explain the difference between these two approaches for intake estimation. Not all foods which may have been canned, particularly canned beverages such as soft drinks, were sampled in our food sampling program. Second, non-food pathways of exposure may be important for adults, including thermal paper exposures, and dust and air exposures. Finally, our canned food concentrations may not be adequately representative of canned foods in the United States; they were found to be generally lower compared to canned food concentrations measured in six other worldwide food surveys including three in North America. Our finding that canned food concentrations greatly exceeded non-canned concentrations was consistent with other studies, and

    Although general parenting styles and restrictive parental feeding practices have been associated with children's weight status, few studies have examined the association between feeding styles and proximal outcomes such as children's food intake, especially in multi-ethnic families with limited incomes. The purpose of this study was to evaluate the association of parental feeding styles and young children's evening food intake in a multiethnic sample of families in Head Start. Participants were 715 Head Start children and their parents from Texas and Alabama representing three ethnic groups: African-American (43%), Hispanic (29%), and White (28%). The Caregivers Feeding Styles Questionnaire (Hughes) was used to characterize authoritative, authoritarian (referent), indulgent or uninvolved feeding styles. Food intake in several food groups was calculated from 3 days of dietary recalls for the child for evening food intakes from 3 PM until bedtime. Compared to children of authoritarian parents, intakes of fruits, juice and vegetables were lowest among children of indulgent or uninvolved parents (1.77 +/- 0.09 vs 1.45 +/- 0.09 and 1.42 +/- 0.11 cups) as were intakes of dairy foods (0.84 +/- 0.05 vs 0.67 +/- 0.05 and 0.63+0.06 cups), respectively. Findings suggest that permissive parent feeding styles like indulgent or uninvolved relate negatively to children's intake of nutrient-rich foods fruit, 100% fruit juice, vegetables and dairy foods from 3 PM until bedtime.

    Full Text Available As the population of the United States continues to age, it has become increasingly more important to recognize the food intake and eating habits of older adults. The objective of this study was to describe the food group intake, factors predicting food group intake, and the food choices of community-dwelling Kansans, 80 years of age and older who participate in congregate meal programs. Participants completed a short questionnaire querying demographic information, current health status, and dietary supplement use. Participants (n = 113 were then followed up via telephone to complete two 24-hour diet recalls. Data were analyzed to determine adequacy of food group intake and mean intake. Regression analyses were used to determine factors predicting intake and frequency analysis established food typically consumed. Female participants were significantly more likely to consume more fruit servings than males. Intake was low for all five of the food groups, especially dairy. Chronic health conditions and dietary supplement use were consistently predictive factors of the amount of each food group consumed.

    Hospital malnutrition is an under-recognized issue that leads to a variety of adverse outcomes, especially for older adults. Food/fluid intake (FFI) monitoring in hospital can be used to identify those who are improving and those who need further treatment. Current monitoring practices such as calorie counts are impractical for all patients and a patient-completed tool, if valid, could support routine FFI monitoring. The aim of this research was to determine whether the patient-completed My Meal Intake Tool (M-MIT) can accurately represent FFI at a single meal. Cross-sectional, multi-site. Four acute care hospitals in Canada. 120 patients (65+ yrs, adequate cognition). Participants completed M-MIT for a single meal. Food and fluid waste was visually estimated by a research dietitian at each hospital. Sensitivity (Se), specificity (Sp) and overall agreement were calculated for both food and fluid intake by comparing M-MIT and dietitian estimations to determine criterion validity of M-MIT. Patient and research dietitian comments were used to make revisions to the M-MIT. Using a cut-point of ≤50% intake, Se was 76.2% and 61.9% and Sp was 74.0% and 80.5% for solid and fluids respectively (pMIT identified a greater proportion of participants (37.2%) as having low FFI (≤50%) than dietitians (25.0%), as well as a greater proportion identified with low fluid intake (28.3% vs. 24.6%). Modest revisions were made to improve the tool. This study has demonstrated initial validity of M-MIT for use in older patients with adequate cognition. Use of M-MIT could promote FFI monitoring as a routine practice to make clinical decisions about care.

    The objectives of this study were to examine the trend in unhealthy food intake by socioeconomic position (SEP) and to determine whether the government's nutritional policies affect socioeconomic disparity in the food intake among adolescents. Data were from the six independent cross-sectional survey data (2006-2011) of Korea Youth Risk Behavior Web-based Survey and included 445,287 subjects aged 12-18 years. The unhealthy food intake was assessed by food frequency intake and SEP was evaluated with the family affluence scale. We observed that unhealthy food intakes decreased through the years, showing the apparent decline when nutritional policies focusing on the restriction of unhealthy foods were implemented, and the trend was all same in the different SEP groups. The pattern of unhealthy food intakes by SEP has changed before and after implementation of the policies. The intakes of carbonated beverages, fast food, and confectioneries were higher in the higher SEP group before implementation of the policies but the difference was not shown after implementation of the policies. The intake of instant noodles was consistently higher in the lower SEP group. The risk of frequent consumption of unhealthy foods was generally more decreased through the years in the higher SEP group than the lower SEP group. In conclusion, this study found the positive effect of nutritional policy on unhealthy food intake among adolescents and the high SEP group appeared to undergo greater desirable changes in dietary behaviors after implementation of nutritional policies than the low SEP group.

    Mathias, Kevin C.; Slining, Meghan M.; Popkin, Barry M.

    2013-01-01

    Background Although consumption of sugar-sweetened beverages (SSBs) is associated with higher caloric intakes, the amount SSBs contribute to higher intakes has not been addressed. Purpose To estimate the amount SSB contribute to higher caloric intakes and determine how the diets of SSB consumers and nonconsumers differ. Methods The WWEI America (What We Eat in America), NHANES 2003–2010 surveys were combined into a sample of 13,421 children; analyses were conducted in December 2012. To determine the contribution of SSB to higher caloric intakes, total non-SSB, food, and non-SSB beverage intakes of SSB consumers and nonconsumers were compared using linear regression models controlling for demographic and socioeconomic factors. Analyses also compared intakes between nonconsumers and SSB consumers with different amounts of SSB consumption. Results For children aged 2–5 years and 6–11 years, non-SSB intakes did not differ between nonconsumers and SSB consumers at any level of SSB consumption, indicating that SSBs were primarily responsible for the higher caloric intakes among SSB consumers. A similar finding was observed among children aged 12–18 years; however, both food and SSB contribute to higher caloric intakes of adolescents consuming ≥500 kcal of SSBs. Among those aged 12–18 years, higher intakes of foods (e.g., pizza, burgers, fried potatoes, and savory snacks) and lower intakes of non-SSB beverages (e.g., fluid milk and fruit juice) were associated with increased SSB intake. Conclusions Sugar-sweetened beverages are primarily responsible for the higher caloric intakes of SSB consumers, and SSB consumption is associated with intake of a select number of food and beverage groups, some of which are often unhealthy (e.g., pizza and grain-based desserts).

    A kind of growth hormone secretagogue (GHS), ghrelin, was first isolated from the rat stomach and plays a major role in the activation of the growth hormone secretagogue receptor 1a (GHS-R1a) resulting the release of growth hormone (GH). The preproghrelin gene is placed on chromosome 3, at locus 3p25 -2 in humans and constitutes five exons and three introns. Ghrelin is most plentifully expressed in particular cells in the oxyntic glands of the gastric epithelium, initially named X/A-like cells. Almost 60-70% of circulating ghrelin is secreted by the stomach. Plasma ghrelin concentration alters throughout the day. Ghrelin has been suggested to act as a meal initiator because of its appetite-stimulating influences in free feeding rats in short period. In addition to ghrelin's function as a meal motivator, it seems to contribute in long-term energy balance and nutritional status. In addition, many studies have been carried out in order to investigate the effects of natural and medicinal plants and botanical extracts on appetite, food intake, energy hemostasis, and the level of related hormones including ghrelin. Due to the importance of ghrelin in nutritional and medical sciences, this review was performed to understand new aspects of this hormone's function.

    Full Text Available Objectives: Insulin signaling in the brain has been implicated in the control of satiety, glucose homeostasis and energy balance. However, insulin signaling is dispensable in energy homeostasis controlling AgRP or POMC neurons and it is unclear which other neurons regulate these effects. Here we describe an ancient insulin/NPY neuronal network that governs energy homeostasis across phyla. Methods: To address the role of insulin action specifically in NPY neurons, we generated a variety of models by selectively removing insulin signaling in NPY neurons in flies and mice and testing the consequences on energy homeostasis. Results: By specifically targeting the insulin receptor in both fly and mouse NPY expressing neurons, we found NPY-specific insulin signaling controls food intake and energy expenditure, and lack of insulin signaling in NPY neurons leads to increased energy stores and an obese phenotype. Additionally, the lack of insulin signaling in NPY neurons leads to a dysregulation of GH/IGF-1 axis and to altered insulin sensitivity. Conclusions: Taken together, these results suggest that insulin actions in NPY neurons is critical for maintaining energy balance and an impairment of this pathway may be causally linked to the development of metabolic diseases.

    Full Text Available The cross-sectional 2007 Australian National Children’s Nutrition and Physical Activity Survey collected detailed dietary information from a representative sample of more than 4400 children by 24-h dietary recall. Dairy food intake by Australian children is substantially lower than recommendations, and decreases as a percentage of energy intake as children grow older. Children aged 2 to 16 years are, on average, 2.3 times more likely to have a dairy food at the first daily occasion of eating, than at the second occasion. For children who consumed any dairy food at the first occasion of eating, the total daily intake of dairy foods was 129% (95% CI 120%–138% greater than for children who did not consume a dairy food at the first occasion of eating. Their dairy food intake for the rest of the day following the first occasion of eating was also greater by 29% (95% CI 21%–37%. Younger age group, male sex, location of eating being at home or in a residence and starting the first occasion of eating from 6 a.m. to 9 a.m. are all jointly associated with having a dairy food at the first occasion of eating. A simple strategy to increase Australian children’s intake from the dairy and alternatives food group may be to make sure that the first occasion of eating each day includes a dairy food or a nutritional equivalent.

    Previous research showed that decreasing the energy density (kJ/g) of foods by adding water to them can lead to reductions in energy intake. Few studies have examined how water consumed as a beverage affects food intake. This study examined the effects of water, both served with a food and incorporated into a food, on satiety. In a within-subjects design, 24 lean women consumed breakfast, lunch, and dinner in our laboratory 1 d/wk for 4 wk. Subjects received 1 of 3 isoenergetic (1128 kJ) preloads 17 min before lunch on 3 d and no preload on 1 d. The preloads consisted of 1) chicken rice casserole, 2) chicken rice casserole served with a glass of water (356 g), and 3) chicken rice soup. The soup contained the same ingredients (type and amount) as the casserole that was served with water. Decreasing the energy density of and increasing the volume of the preload by adding water to it significantly increased fullness and reduced hunger and subsequent energy intake at lunch. The equivalent amount of water served as a beverage with a food did not affect satiety. Energy intake at lunch was 1209 +/- 125 kJ after the soup compared with 1657 +/- 148 and 1639 +/- 148 kJ after the casserole with and without water, respectively. Subjects did not compensate at dinner for this reduction in lunch intake. Consuming foods with a high water content more effectively reduced subsequent energy intake than did drinking water with food.

    Full Text Available Fiber continues to be singled out as a nutrient of public health concern. Adequate intakes of fiber are associated with reduced risk for cardiovascular disease, cancer, diabetes, certain gastrointestinal disorders and obesity. Despite ongoing efforts to promote adequate fiber through increased vegetable, fruit and whole-grain intakes, average fiber consumption has remained flat at approximately half of the recommended daily amounts. Research indicates that consumers report increasingly attempting to add fiber-containing foods, but there is confusion around fiber in whole grains. The persistent and alarmingly low intakes of fiber prompted the “Food & Fiber Summit,” which assembled nutrition researchers, educators and communicators to explore fiber’s role in public health, current fiber consumption trends and consumer awareness data with the objective of generating opportunities and solutions to help close the fiber gap. The summit outcomes highlight the need to address consumer confusion and improve the understanding of sources of fiber, to recognize the benefits of various types of fibers and to influence future dietary guidance to provide prominence and clarity around meeting daily fiber recommendations through a variety of foods and fiber types. Potential opportunities to increase fiber intake were identified, with emphasis on meal occasions and food categories that offer practical solutions for closing the fiber gap.

    We aimed to assess dietary profiles of adults from the NutriNet-Santé cohort according to different levels of organic food consumption using detailed self-reported data on organic food intakes. Food intakes were obtained using an organic food frequency questionnaire (Org-FFQ). The participants were ranked into five groups (quintiles, Q) according to the proportion of organic foods in their diet. To determine diet quality, two scores were computed reflecting adherence to food-based recommendations (mPNNS-GS) and the probability of adequate nutrient intake (PANDiet). Relationships between levels of organic food consumption and dietary characteristics were assessed using multivariable-adjusted ANCOVA models. The NutriNet-Santé Study. French adults from the NutriNet-Santé Study (n 28 245). Intakes of foods of plant origin increased along with the contribution of organic foods to the diet while a reverse trend was identified for dairy products, cookies and soda (P-trendfood consumers exhibited better diet quality, although intermediate organic food consumers showed better adherence to specific nutritional recommendations related to animal products. The study provides new insights into the understanding of organic food consumption as a part of a healthy diet and sheds some light on the dietary profiles of different categories of organic food consumers. These results underline strong dietary behaviour correlates associated with organic food consumption that should be controlled for in future aetiological studies on organic foods and health.

    To examine the effects of perceived availability of fast-food shops, restaurants, and convenience stores on adolescent dietary intakes. Survey data from 34 369 students in 42 Hong Kong secondary schools were collected in 2006-7. Respondents reported the availability of fast-food shops, restaurants and convenience stores in the neighbourhood, and their intakes of fruit, vegetables, high-fat foods and junk food/soft drinks. For intakes of high-fat foods and junk food/ soft drinks, ≤ once a week was defined as low consumption and the rest moderate/high consumption. At least three servings of vegetables and two servings of fruit daily were defined as sufficient consumption. Logistic regression yielded adjusted odds ratios (OR) for each dietary intake in relation to the reported food shops. Potential effect modifications by socio-demographic factors were also examined. Perceived availability of fast-food shops and convenience stores were positively associated with moderate/high consumptions of high-fat foods (OR(fast) =1.10 and OR(con) =1.15) and junk food/soft drinks (OR(fast)=1.10 and OR(con) =1.10). Significant negative associations of the perceived availability of restaurants with intakes of vegetables and fruit were observed (OR(veg) =0.87 and OR(fruit) =0.83). The positive relationship between reporting fast-food shops with intake of junk food/soft drinks were observed only in boys and those with low perceived family affluence. The negative association of reporting restaurants with fruit consumption was found in those with low and middle perceived family affluence only. Perceived availability of neighbourhood fast-food shops, restaurants, and convenience stores may have a negative impact on adolescent dietary intakes particularly for those from poorer families.

The adult subjects were selected from 9 cities of Beijing, Shanghai, Chongqing, Shenyang, Harbin, Jinan, Zhengzhou, Changsha, Nanning. The recording method for 7 consecutive days was used to collect pre-packaged foods consumption information. Among subjects, the median intake of energy, protein, fat and carbohydrate from pre-packaged foods were 628. 8kJ/d, 5.0 g/d, 6.7 g/d and 17.0 g/d, respectively. Among consumers, the median intake of energy, protein, fat and carbohydrate from pre-packaged foods were 745. 3 kJ/d, 6. 0 g/d, 7. 7 g/d and 20. 7 g/d, respectively. The energy and macronutrients intake from pre-packaged foods were at low level.

    The abundance of highly palatable food items in our environment represents a possible cause of overconsumption. Neuroimaging studies in humans have demonstrated that watching pictures of food increases activation in brain areas involved in homeostatic and hedonic food cue processing. Nevertheless, the impact of food cues on actual food intake and metabolic parameters has not been systematically investigated. We tested the hypothesis that watching high-calorie food cues increases food intake and modifies anticipatory blood parameters in lean and especially in obese men. In 20 normal-weight and 20 obese healthy fasted men, we assessed the effects of watching pictures of high-calorie food items versus neutral contents on food intake measured during a standardized test buffet and subsequent snacking as well as on glucose homeostasis and endocrine parameters. Compared to neutral pictures, viewing food pictures reduced postprandial blood glucose concentrations in lean (p = 0.016) and obese (p = 0.044) subjects, without any differences in insulin or C-peptide concentrations (all p > 0.4). Viewing food pictures did not affect total calorie intake during the buffet (all p > 0.5) and snack consumption (all p > 0.4). Concentrations of ghrelin, adrenocorticotropic hormone (ACTH), cortisol, and glucagon also remained unaffected (all p > 0.08). These data indicate that preprandial processing of food cues curbs postprandial blood glucose excursions, without immediately affecting eating behavior in normal-weight and obese men. Findings indicate that exposure to food cues does not acutely trigger calorie overconsumption but rather improves the glucoregulatory response to food intake. Copyright © 2017 Elsevier Ltd.

    2010-02-01

    The reinforcing value of food plays a role in food consumption. We have shown previously that daily intake of a high-energy-density (HED) snack food decreases food reinforcement and food liking in nonobese women but increases food reinforcement and decreases food liking in obese women. These previous studies were conducted with the use of only HED snack foods. The purpose of this study was to determine whether these effects generalize to low-energy-density (LED) foods. Participants (n = 53) had food reinforcement and food liking tested at baseline and then again after 2 wk of daily consumption of 60-g portions of an HED (n = 26) or an LED (n = 27) snack food. We observed a decrease in food reinforcement in women with a lower body mass index (BMI) and an increase in food reinforcement in women with a higher BMI after 14 d of consumption of an HED snack food. Food liking decreased in all women, regardless of BMI, after repeated consumption of HED foods. Conversely, all women, regardless of BMI, showed a decrease in food reinforcement after 14 d of LED snack food consumption. Women with a lower BMI who consumed LED snacks also showed a decrease in liking, but women with a higher BMI who consumed LED foods reported no change in liking. These findings suggest that changes in food reinforcement after daily snack food intake are influenced by both BMI and the energy density of the foods. In addition, changes in food reinforcement cannot be explained by changes in food liking.

    The Potential Weekly Intake (PWI) of artificial food colours by 3-14-year-old children living in the District of Barão Geraldo, Campinas, São Paulo, Brazil, was estimated on the basis of average consumption data of artificially coloured food and analytically determined colour concentration in foodstuffs ingested. Coloured food consumption data were obtained through dietary recall interviews and collection of the packages and/or labels of the coloured foods consumed during a two-week period. Colours found in the individual types of foods detected through the consumption survey were identified and determined by methods that included wool dyeing and polyamide column extractions, ascending paper chromatography and spectrophotometry. The results showed that all artificial colours used in the composition of 83 commercial food products, including jellies, juices, soft drinks, syrups and 57 different candies, were permitted for use in food in Brazil the year the survey was conducted (1986), in amounts below those prescribed by law. Statistical analysis performed to compare the PWI for different population groups demonstrated that young male children, especially from lower social classes, were most exposed to artificial colours. Comparison of the estimated potential intakes with the toxicologically Acceptable Daily Intake (ADI) showed that consumption of Amaranth, Sunset Yellow, Indigotine and Tartrazine by all children in the study represented approximately 24%, 3%, 0.05% and 0.4%, of the actual ADI values, respectively.

    2010-12-01

    To calculate total intake of a nutrient and estimate inadequate intake for a population, the amounts derived from food/beverages and from vitamin/mineral supplements must be combined. The two methods Statistics Canada has suggested present problems of interpretation. Data collected from 34,386 respondents to the 2004 Canadian Community Health Survey-Nutrition were used to compare four methods of combining nutrient intake from food/beverages and vitamin/mineral supplements: adding average intake from supplements to the 24-hour food/beverage recall and estimating the usual distribution in the population (Method 1); estimating usual individual intake from food? beverages and adding intake from supplements (Method 2); and dividing the population into supplement users and non-users and applying Method 1 or Method 2 and combining the estimates based on the percentages of users and non-users (Methods 3 and 4). Interpretation problems arise with Methods 1 and 2; for example, the percentage of the population with inadequate intake of vitamin C and folate equivalents falls outside the expected minimum-maximum range. These interpretation problems are not observed with Methods 3 and 4. Interpretation problems that may arise in combining food and supplement intake of a given nutrient are overcome if the population is divided into supplement users and non-users before Method 1 or Method 2 is applied.

    The main goal of this study was to test whether exposure to happy, neutral, or sad media content influences social modeling effects of (snack) food intake in young children. The study was conducted at 14 Dutch urban and suburban primary schools. The participants (N=112) were asked to watch a movie with a same-sex normal-weight confederate who was instructed to eat either nothing or a standardized amount of snack food (10 chocolate-coated peanuts). The study involved a 3 (movie clips: happy, neutral, and sad)×2 (peer's food intake: no intake versus a standardized intake) between-participants design. A significant interaction between the movie clip condition and intake condition was found (F(2,102)=3.30, P=.04, Cohen's f(2)=.20). Positive as well as negative emotions were found to lead to adjustment to the intake of a peer, as compared to that of children in the neutral movie condition. The findings suggest that children eat more mindlessly when watching an emotional movie and, therefore, respond more automatically to a peer's food intake, whereas children may be less susceptible to a peer's intake while watching a neutral movie. As young children are not in the position to choose their food consumption environment yet, parents and schools should provide consumption settings that limit eating in front of the television.

    Parents play an important role in shaping children's eating habits. Few studies have evaluated the influence of both parenting style and parenting practices on child outcomes such as dietary intake. During spring 2007, 99 parent-child dyads from four rural US areas participated in this cross-sectional study. Child food intake was reported during two interviewer-administered, parent-assisted 24-hour recalls. Diet quality was defined as the average number of low-nutrient-dense (LND) foods consumed. Validated questionnaires were used to assess parental feeding practices and feeding style. Pearson correlations identified relationships among child food intake, parental feeding style typologies, and covariates. Regression analyses were used to predict child diet quality. Sixty percent of children and 76% of parents were overweight or obese. A permissive feeding style, which is highly responsive to a child's requests and sets few demands on him or her, was the most common (n=37) parental feeding style. This feeding style was associated with child intake of LND foods (r=0.3; Pparental feeding practices and child intake of LND foods. In the presence of a permissive feeding style, higher levels of monitoring were associated with child intake of LND foods (β=.69; PParental feeding style may alter the effectiveness of parental feeding practices on children's food intake.

    Here we sought to determine whether ghrelin's central effects on food intake can be interrupted by nicotine acetylcholine receptor (nAChR) blockade. Ghrelin regulates mesolimbic dopamine neurons projecting from the ventral tegmental area (VTA) to the nucleus accumbens, partly via cholinergic VTA afferents originating in the laterodorsal tegmental area (LDTg). Given that these cholinergic projections to the VTA have been implicated in natural as well as drug-induced reinforcement, we sought to investigate the role of cholinergic signaling in ghrelin-induced food intake as well as fasting-induced food intake, for which endogenous ghrelin has been implicated. We found that i.p. treatment with the non-selective centrally active nAChR antagonist, mecamylamine decreased fasting-induced food intake in both mice and rats. Moreover, central administration of mecamylamine decreased fasting-induced food intake in rats. I.c.v. ghrelin-induced food intake was suppressed by mecamylamine i.p. but not by hexamethonium i.p., a peripheral nAChR antagonist. Furthermore, mecamylamine i.p. blocked food intake following ghrelin injection into the VTA. Expression of the ghrelin receptor, the growth hormone secretagogue receptor 1A, was found to co-localize with choline acetyltransferase, a marker of cholinergic neurons, in the LDTg. Finally, mecamylamine treatment i.p. decreased the ability of palatable food to condition a place preference. These data suggest that ghrelin-induced food intake is partly mediated via nAChRs and that nicotinic blockade decreases the rewarding properties of food. Copyright © 2010 IBRO.

  14. Nutritional modelling: distributions of salt intake from processed foods in New Zealand.

    Science.gov (United States)

    Thomson, Barbara M

    2009-09-01

    The salt content of processed foods is important because of the high intake of Na by most New Zealanders. A database of Na concentrations in fifty-eight processed foods was compiled from existing and new data and combined with 24 h diet recall data from two national nutrition surveys (5771 respondents) to derive salt intakes for seven population groups. Mean salt intakes from processed foods ranged from 6.9 g/d for young males aged 19-24 years to 3.5 g/d for children aged 5-6 years. A total of > or = 50 % of children aged 5-6 years, boys aged 11-14 years and young males aged 19-24 years had salt intakes that exceeded the upper limit for Na, calculated as salt (3.2-5.3 g/d), from processed foods only. Bread accounted for the greatest contribution to salt intake for each population group (35-43 % of total salt intake). Other foods that contributed 2 % or more and common across most age groups were sausage, meat pies, pizza, instant noodles and cheese. The Na concentrations of key foods have changed little over the 16-year period from 1987 to 2003 except for corned beef and whole milk that have decreased by 34 and 50 % respectively. Bread is an obvious target for salt reduction but the implication on iodine intake needs consideration as salt is used as a vehicle for iodine fortification of bread.

    A range of psychophysical taste measurements are used to characterize an individual's sweet taste perception and to assess links between taste perception and dietary intake. The aims of this study were to investigate the relationship between four different psychophysical measurements of sweet taste perception, and to explore which measures of sweet taste perception relate to sweet food intake. Forty-four women aged 20-40 years were recruited for the study. Four measures of sweet taste perception (detection and recognition thresholds, and sweet taste intensity and hedonic liking of suprathreshold concentrations) were assessed using glucose as the tastant. Dietary measurements included a four-day weighed food record, a sweet food-food frequency questionnaire and a sweet beverage liking questionnaire. Glucose detection and recognition thresholds showed no correlation with suprathreshold taste measurements or any dietary intake measurement. Importantly, sweet taste intensity correlated negatively with total energy and carbohydrate (starch, total sugar, fructose, glucose) intakes, frequency of sweet food intake and sweet beverage liking. Furthermore, sweet hedonic liking correlated positively with total energy and carbohydrate (total sugar, fructose, glucose) intakes. The present study shows a clear link between sweet taste intensity and hedonic liking with sweet food liking, and total energy, carbohydrate and sugar intake.

    Full Text Available Background: The evidence suggests a relationship between lifestyle and diet-related risk factors.Objective: This study assessed the dietary intake and habits of high school girls in Sistan and Bluchistan province, in southeastern Iran.Methods: In a cross-sectional, descriptive study, 753 high school girls aged 14-18 years old wereenrolled by a clustered random sampling method. Dietary intake and food habits were evaluatedby a two-day, 24-hour dietary recall, and a food frequency questionnaire (FFQ.Results: The analysis of dietary intakes showed that energy, calcium, zinc, vitamin C and folate intake, compared to the Dietary Reference Intake (DRI, were found to be lower. The, infrequent intake of milk and dairy products, fruits and vegetables, and a high consumption of empty calorie foods e.g. salty snacks, sweets, soft drinks and junk foods were seen among adolescents.Conclusions: The adolescent girls had an improper dietary intake and food habits. Thus, the implementation of nutrition education programs in schools and the designing of proper patternstowards healthier food choices could help improve eating behaviors, the health maintenance of adolescents, and also prevent diet- related diseases in adulthood.

    The study reported herein was initiated to examine dietary tin intake (Sn-D) in Japan to elucidate the possible effects of consumption of canned food (including beverages) on Sn-D, and to compare the intake among regions and between the two sexes in reference to the current provisional tolerable weekly intake and intake in other countries. Urinary tin levels (Sn-U) were also studied. Duplicate diet samples (24 h) together with records of food intake were collected in 1999-2004 from 111 adult residents in four areas of Japan. After exclusion of incomplete samples, 95 valid samples were subjected to determination of tin by inductively coupled plasma mass spectrometry (ICP-MS) after acid digestion. Among the 95 cases, 37 women additionally provided urine samples. Distribution of Sn-D was markedly skewed. Median Sn-D was 5.6 microg day(-1) for total subjects, which was about one-tenth of the values previously reported for the Japanese population; the difference was most probably attributable to the difference in the methods of determination. Consumption of canned foods led to a substantial increase in Sn-D. Thus, the median Sn-D for canned food consumers of 35.7 microg day(-1), was eight-fold higher than the median Sn-D for non-consumers of 4.5 microg day(-1). Sn-U (as corrected for creatinine concentration) distributed log-normally with a geometric mean of 2.0 microg (g cr)(-1). No effect of canned food consumption was evident on Sn-U. When compared internationally, Sn-D for the Japanese population was substantially lower than Sn-D for populations in other industrialized countries.

    Literature suggests that people living in areas with a wealth of unhealthy fast food options may show higher levels of fast food intake. Multilevel logistic regression analyses were applied to examine the association between GIS-located fast food outlets (FFOs) and self-reported fast food intake among adults (+ 16 years) in the Capital Region of Denmark (N = 48,305). Accessibility of FFOs was measured both as proximity (distance to nearest FFO) and density (number of FFOs within a 1km network buffer around home). Odds of fast food intake ≥ 1/week increased significantly with increasing FFO density and decreased significantly with increasing distance to the nearest FFO for distances ≤ 4km. For long distances (>4km), odds increased with increasing distance, although this applied only for car owners. Results suggest that Danish health promotion strategies need to consider the contribution of the built environment to unhealthy eating. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Consumers in the UK responded to the rapid increases in food prices between 2007 and 2009 partly by reducing the amount of food energy bought. Household food and drink waste has also decreased since 2007. The present study explored the combined effects of reductions in food purchases and waste on estimated food energy intakes and dietary energy density. The amount of food energy purchased per adult equivalent was calculated from Kantar Worldpanel household food and drink purchase data for 2007 and 2012. Food energy intakes were estimated by adjusting purchase data for food and drink waste, using waste factors specific to the two years and scaled for household size. Scotland. Households in Scotland (n 2657 in 2007; n 2841 in 2012). The amount of food energy purchased decreased between 2007 and 2012, from 8·6 to 8·2 MJ/adult equivalent per d (Pfood waste, estimated food energy intake was not significantly different (7·3 and 7·2 MJ/adult equivalent per d for 2007 and 2012, respectively; P=0·186). Energy density of foods purchased increased slightly from 700 to 706 kJ/100 g (P=0·010). While consumers in Scotland reduced the amount of food energy that they purchased between 2007 and 2012, this was balanced by reductions in household food and drink waste over the same time, resulting in no significant change in net estimated energy intake of foods brought into the home.

    Full Text Available Hypothalamus is a key area involved in the control of metabolism and food intake via the integrations of numerous signals (hormones, neurotransmitters, metabolites from various origins. These factors modify hypothalamic neurons activity and generate adequate molecular and behavioral responses to control energy balance. In this complex integrative system, a new concept has been developed in recent years, that includes reactive oxygen species (ROS as a critical player in energy balance. ROS are known to act in many signaling pathways in different peripheral organs, but also in hypothalamus where they regulate food intake and metabolism by acting on different types of neurons, including proopiomelanocortin (POMC and agouti-related protein (AgRP/neuropeptide Y (NPY neurons. Hypothalamic ROS release is under the influence of different factors such as pancreatic and gut hormones, adipokines (leptin, apelin,..., neurotransmitters and nutrients (glucose, lipids,.... The sources of ROS production are multiple including NADPH oxidase, but also the mitochondria which is considered as the main ROS producer in the brain. ROS are considered as signaling molecules, but conversely impairment of this neuronal signaling ROS pathway contributes to alterations of autonomic nervous system and neuroendocrine function, leading to metabolic diseases such as obesity and type 2 diabetes.In this review we focus our attention on factors that are able to modulate hypothalamic ROS release in order to control food intake and energy metabolism, and whose deregulations could participate to the development of pathological conditions. This novel insight reveals an original mechanism in the hypothalamus that controls energy balance and identify hypothalamic ROS signaling as a potential therapeutic strategy to treat metabolic disorders.

    High-throughput screening techniques that analyze the metabolic endpoints of biological processes can identify the contributions of genetic predisposition and environmental factors to the development of common diseases. Studies applying controlled physiological challenges can reveal dysregulation in metabolic responses that may be predictive for or associated with these diseases. However, large-scale epidemiological studies with well controlled physiological challenge conditions, such as extended fasting periods and defined food intake, pose logistic challenges. Culturally and religiously motivated behavioral patterns of life style changes provide a natural setting that can be used to enroll a large number of study volunteers. Here we report a proof of principle study conducted within a Muslim community, showing that a metabolomics study during the Holy Month of Ramadan can provide a unique opportunity to explore the pre-prandial and postprandial response of human metabolism to nutritional challenges. Up to five blood samples were obtained from eleven healthy male volunteers, taken directly before and two hours after consumption of a controlled meal in the evening on days 7 and 26 of Ramadan, and after an over-night fast several weeks after Ramadan. The observed increases in glucose, insulin and lactate levels at the postprandial time point confirm the expected physiological response to food intake. Targeted metabolomics further revealed significant and physiologically plausible responses to food intake by an increase in bile acid and amino acid levels and a decrease in long-chain acyl-carnitine and polyamine levels. A decrease in the concentrations of a number of phospholipids between samples taken on days 7 and 26 of Ramadan shows that the long-term response to extended fasting may differ from the response to short-term fasting. The present study design is scalable to larger populations and may be extended to the study of the metabolic response in defined patient

  4. Central dopaminergic circuitry controlling food intake and reward: implications for the regulation of obesity.

    Vucetic, Zivjena; Reyes, Teresa M

    2010-01-01

    Prevalence of obesity in the general population has increased in the past 15 years from 15% to 35%. With increasing obesity, the coincident medical and social consequences are becoming more alarming. Control over food intake is crucial for the maintenance of body weight and represents an important target for the treatment of obesity. Central nervous system mechanisms responsible for control of food intake have evolved to sense the nutrient and energy levels in the organism and to coordinate appropriate responses to adjust energy intake and expenditure. This homeostatic system is crucial for maintenance of stable body weight over long periods of time of uneven energy availability. However, not only the caloric and nutritional value of food but also hedonic and emotional aspects of feeding affect food intake. In modern society, the increased availability of highly palatable and rewarding (fat, sweet) food can significantly affect homeostatic balance, resulting in dysregulated food intake. This review will focus on the role of hypothalamic and mesolimbic/mesocortical dopaminergic (DA) circuitry in coding homeostatic and hedonic signals for the regulation of food intake and maintenance of caloric balance. The interaction of dopamine with peripheral and central indices of nutritional status (e.g., leptin, ghrelin, neuropeptide Y), and the susceptibility of the dopamine system to prenatal insults will be discussed. Additionally, the importance of alterations in dopamine signaling that occur coincidently with obesity will be addressed.

    Increased production and consumption of local food may reduce the negative environmental, social, and economic impacts of industrialized and globalized food production. Here we examined potential barriers to increasing production and consumption of food produced in Iceland. First, we developed a new framework to address the behaviors of production and consumption simultaneously, to comprehensively analyze their potential barriers. We examined structural barriers by estimating the food production capacity of Iceland, and cultural and personal barriers through survey data on cultural norms and purchasing behavior from Matís, a research and development company. We found no structural barriers preventing Iceland from increasing production of local cereals, which would compliment current local production of meat and dairy and reduce reliance on imports, currently at 50% of the daily caloric intake. However, if food production became entirely local without changing the current mix of crops grown, there would be a 50% reduction in diversity (from 50 to 25 items in eight out of ten food categories). We did not identify any cultural barriers, as survey results demonstrated that consumers hold generally positive worldviews towards local food, with 88% satisfied with local food they had purchased. More than two-thirds of consumers regarded supporting the local farmer and considerations such as environmentally friendly production, fewer food miles, lower carbon footprint as important. However, they rated the local food they have access to as lower in meeting sustainability criteria, showing that they make justifications for not choosing local food in practice. This is a personal barrier to increased consumption of local food, and implies that marketing strategies and general knowledge connected to local food in Iceland might be improved. Although the results apply to the case of Iceland, the method of identifying behavioral barriers to change is applicable to other countries

    Full Text Available The aims of this study were to assess the relative validity and reproducibility of a semi-quantitative food-frequency questionnaire (FFQ applied in a large region-wide survey among 2.5-6.5 year-old children for estimating food group intakes. Parents/guardians were used as a proxy. Estimated diet records (3d were used as reference method and reproducibility was measured by repeated FFQ administrations five weeks apart. In total 650 children were included in the validity analyses and 124 in the reproducibility analyses. Comparing median FFQ1 to FFQ2 intakes, almost all evaluated food groups showed median differences within a range of ± 15%. However, for median vegetables, fruit and cheese intake, FFQ1 was > 20% higher than FFQ2. For most foods a moderate correlation (0.5-0.7 was obtained between FFQ1 and FFQ2. For cheese, sugared drinks and fruit juice intakes correlations were even > 0.7. For median differences between the 3d EDR and the FFQ, six food groups (potatoes & grains; vegetables Fruit; cheese; meat, game, poultry and fish; and sugared drinks gave a difference > 20%. The largest corrected correlations (>0.6 were found for the intake of potatoes and grains, fruit, milk products, cheese, sugared drinks, and fruit juice, while the lowest correlations (<0.4 for bread and meat products. The proportion of subjects classified within one quartile (in the same/adjacent category by FFQ and EDR ranged from 67% (for meat products to 88% (for fruit juice. Extreme misclassification into the opposite quartiles was for all food groups < 10%. The results indicate that our newly developed FFQ gives reproducible estimates of food group intake. Overall, moderate levels of relative validity were observed for estimates of food group intake.

    The aim of this systematic review and meta-analysis was to assess the effect of season on food intake from selected food groups and on energy intake in adults. The search process was based on selecting publications listed in the following: Medline, Scopus, Web of Science, Embase and Agris. Food frequency questionnaires, 24-h dietary recalls and food records as methods for assessment of dietary intake were used to assess changes in the consumption of 11 food groups and of energy intake across seasons. A meta-analysis was performed. Twenty-six studies were included. Articles were divided into those reporting data on four seasons (winter, spring, summer and autumn) or on two seasons (pre-and post-harvest). Four of the studies could be utilized for meta-analysis describing changes in food consumption across four season scheme: from winter to spring fruits decreased, whereas vegetables, eggs and alcoholic beverages increased; from spring to summer vegetable consumption further increased and cereals decreased; from summer to autumn fruits and cereals increased and vegetables, meat, eggs and alcoholic beverages decreased; from autumn to winter cereals decreased. A significant association was also found between energy intake and season, for 13 studies reporting energy intake across four seasons (favors winter) and for eight studies across pre- and post-harvest seasons (favors post-harvest). The winter or the post-harvest season is associated with increased energy intake. The intake of fruits, vegetables, eggs, meat, cereals and alcoholic beverages is following a seasonal consumption pattern and at least for these foods season is determinant of intake.

    Both obesity and immigration continue to increase in the United States. Studies suggest that a transition in lifestyle patterns, such as food intake, may mediate the relationship between immigration and obesity. We examine obesity among hotel workers in relation to age, sex, race/ethnicity, and indicators of food intake, immigration, and acculturation. Four thousand five hundred thirty hotel workers in 30 hotels were studied from the first year of the Work, Weight and Wellness program, before intervention (during 2005-2006). Weight and height were measured, whereas race/ethnicity, language, education, immigration, acculturation, and food intake variables were assessed by questionnaire. The study included 43% male and 57% female hotel workers (mean age 44.4+/-11.3 years; 42% Filipino, 32% other Asian, 13% Pacific Islander, 9% white, 1% black/African American, and 3% other race/ethnicity). On average (mean value), 55% of participants were born outside the United States; 57% were overweight or obese (body mass index [BMI] >25). The BMI of those born in the United States was 1.3 higher than that of those born in another country, adjusting for sex and race/ethnicity. Intake of sweet drinks and meat was positively associated with BMI while intake of fruit was negatively associated with BMI. Age at arrival in United States ("generation") was negatively associated with BMI, whereas greater acculturation was positively associated with BMI. Food intake behaviors are probably related to place of birth, generation of migration to the United States, and acculturation. Direct measures of food intake added explanatory power to models, suggesting the importance of food intake to obesity. Further study of the influence of immigration, acculturation, and food intake on obesity using longitudinal study designs is warranted.

    To investigate whether active school transport was associated with fast food consumption, and to examine differences across racial/ethnic groups. Adolescent data (n=3194) from the 2009 California Health Interview Survey were analyzed with logistic regression models to examine the association between active school transport (AST) and fast food intake across racial/ethnic groups. In the overall sample, AST during 1-2days in the past week was associated with greater likelihood of fast food intake (OR: 1.58; 95% CI: 1.03-2.43), compared with zero days of AST, controlling for demographic and other factors. The association between AST and fast food intake differed significantly by race/ethnicity (pfast food intake (1-2days OR, 2.37, 95%CI: 1.05-5.35; 3-4days OR, 2.78, 95% CI: 1.04-7.43; 5days OR, 2.20, 95%CI: 1.23-3.93). Among White and Asian adolescents, there was a curvilinear pattern: relative to adolescents who reported zero days of AST, those who did AST 1-2days/week had greater likelihood of fast food intake, but AST of 3-4days and 5days/week was associated respectively, with higher and lower likelihood of fast food intake among both groups. AST appears to be a risk factor for fast food intake, and may expose some ethnic groups more than others to increased opportunity to purchase and consume fast food. Programs and policies to promote AST among adolescents should incorporate efforts to encourage healthy eating and discourage concentration of fast food outlets near schools.

    Full Text Available Economic growth in developing countries and globalization of the food sector is leading to increasingly similar food consumption patterns worldwide. The aim of this study was to describe similarities and differences in the contributions of main food groups to energy and nutrient intakes in five developed countries across three continents. We obtained summary reports of national food consumption survey data from Australia, France, Denmark, the Netherlands, and the United States. Survey years spanned 2003–2012; sample size ranged from 1444 to 17,386. To mitigate heterogeneity of food groups across countries, we recategorized each survey’s reported food groups and subgroups into eight main food groups and, for three countries, a ninth “mixed dishes” group. We determined the percent contribution of each food group to mean daily intakes of energy, saturated fat, sodium, fiber, and ten vitamins and minerals that are commonly under-consumed. Differences in findings from surveys utilizing a foods-as-consumed versus a disaggregated or ingredients approach to food group composition and contributions from the milk and milk products group, a source of several under-consumed nutrients, were explored. Patterns of food group contributions to energy and nutrient intakes were generally similar across countries. Some differences were attributable to the analytical approach used by the surveys. For the meat/protein, milk and milk products, vegetables, and fruit groups, percent contributions to key nutrient intakes exceeded percent contributions to energy intake. The mixed dishes group provided 10%–20% of total daily energy and a similar 10%–25% of the daily intake of several nutrients. This descriptive study contributes to an understanding of food group consumption patterns in developed countries.

This descriptive study contributes to an understanding of food group consumption patterns in developed countries. PMID:26061017

    OBJECTIVE Prokineticin 2 (PK2) is a hypothalamic neuropeptide expressed in central nervous system areas known to be involved in food intake. We therefore hypothesized that PK2 plays a role in energy homeostasis. RESEARCH DESIGN AND METHODS We investigated the effect of nutritional status on hypothalamic PK2 expression and effects of PK2 on the regulation of food intake by intracerebroventricular (ICV) injection of PK2 and anti-PK2 antibody. Subsequently, we investigated the potential mechanis...

    Based on the literature, the ARC is the part of brain where some neurotransmitters exert the most potent orexigenic or anorexigenic effects in mammals and birds. Food intake is inhibited by leptin, insulin, αMSH, and serotonin and activated by NP Y, Agrp, NO F/Q, and GABA. However, a few neurotransmitter such as ghrelin has a dual function, ghrelin stimulates feeding in mammals, although it attenuates food intake in birds.

    Fasting affects the body retention and tissue distribution of Ga-67 in experimental animals. In Ga-67 experiments, therefore, a difference in food intake between treated and control animals might result in confusing side effects. We have observed this in irradiation studies. It is suggested that a fasting regimen should be imposed in any Ga-67 animal study where an alteration in food intake might be experienced in the treated group

    The home food environment is known to influence children's diet and selected health outcomes. However, similar research in adults is scarce. The home is arguably the most important food environment for New Zealand adults as the majority of food consumed is stored and prepared in the home. Therefore we investigated relationships between home food availability and nutrient intake in 50 year olds from Canterbury, New Zealand. A cross-sectional study where participants completed a home food inventory and a four-day estimated food diary. Regression analysis was used to investigate relationships between home availability of 'Fruit and Vegetables' and 'Obesogenic Foods' and intake of selected nutrients, adjusting for Body Mass Index and demographic factors. Men and women (n=216) aged 50 were randomly selected from Canterbury District Health Board area electoral rolls. Women with a high 'Obesogenic Foods' score were significantly more likely to have a high intake of saturated fat (OR 5.8, CI: 1.67, 19.6) and high sugar intake (OR 3.1, CI: 1.23, 7.58). Men with a high 'Obesogenic Foods' score were less likely to have high folate (OR 0.14, CI: 0.05, 0.40) and fibre intake (OR 0.21, CI: 0.07, 0.60). Men and women with a higher 'Fruit and Vegetables' score were more likely to have high vitamin C intake (OR 5.6 and 4.5 respectively). Home Food Inventory scores are associated with selected nutrient intakes, particularly in women, suggesting that they are useful for identifying those groups with less favourable nutrient intakes. Future research should investigate whether these scores can predict health outcomes.

    Current explanations of health inequalities in adolescents focus on behavourial and economic determinants and rarely include more meaningful forms of economic, cultural, and social capital. The aim of the study was to investigate how the interplay between capitals constitutes social inequalities in adolescent healthy food intake. Data were collected in the 2013/14 Flemish Health Behavior among School-aged Children (HBSC) survey, which is part of the international WHO HBSC survey. The total sample included 7266 adolescents aged 12-18. A comprehensive set of 58 capital indicators was used to measure economic, cultural and social capital and a healthy food index was computed from a 17-item food frequency questionnaire (FFQ) to assess the consumption frequency of healthy food within the overall food intake. The different forms of capital were unequally distributed in accordance with the subdivisions within the education system. Only half of the capital indicators positively related to healthy food intake, and instead 17 interactions were found that both increased or reduced inequalities. Cultural capital was a crucial component for explaining inequalities such that social gradients in healthy food intake increased when adolescents participated in elite cultural practices ( P economic, cultural and social capital may both increase or reduce healthy food intake inequalities in adolescents. Policy action needs to take into account the unequal distribution of these resources within the education system. © The Author 2016.

    Abstract Obesity is an increasing problem and identification of the driving forces for overeating of energy‐rich food is important. Previous studies show that the stress and sex steroid allopregnanolone has a hyperphagic effect on both bland food and palatable food. If allopregnanolone induces a preference for more palatable or for more energy‐rich food is not known. The aim of this study was to elucidate the influence of allopregnanolone on food preference. Male Wistar rats were subjected to two different food preference tests: a choice between standard chow and cookies (which have a higher energy content and also are more palatable than chow), and a choice between a low caloric sucrose solution and standard chow (which has a higher energy content and is less palatable than sucrose). Food intake was measured for 1 h after acute subcutaneous injections of allopregnanolone. In the choice between cookies and chow allopregnanolone significantly increased only the intake of cookies. When the standard chow was the item present with the highest caloric load, the chow intake was increased and allopregnanolone had no effect on intake of the 10% sucrose solution. The increased energy intakes induced by the high allopregnanolone dose compared to vehicle were very similar in the two tests, 120% increase for cookies and 150% increase for chow. It appears that in allopregnanolone‐induced hyperphagia, rats choose the food with the highest energy content regardless of its palatability. PMID:25501437

    Full Text Available Objective: The aim of the study was to identify the ethnic differences in dietary patterns and its association with socio-economic, dietary and lifestyle practices among adolescents in Kelantan, Malaysia. Methods: A population-based study of 454 adolescents aged 12 to 19 years was included. A validated food frequency questionnaire was used to assess dietary patterns and three dietary patterns were identified based on the principal component analysis method. Results: Malay adolescents had significantly higher scores for the Western-based food pattern and local-based food pattern, whereas Chinese adolescents showed higher scores for the healthy-based food pattern. Multivariate analyses show that age and physical activity (PA levels were positively associated with healthy-based food pattern in Malay (All, p < 0.001, whereas higher consumption of eating-out from home (EatOut (p = 0.014 and fast food (p = 0.041 were negatively associated. High weekly breakfast skipping (p < 0.001 and EatOut (p = 0.003 were positively associated with a Western-based pattern, whereas age (p < 0.001 and household income (p = 0.005 were negatively associated. Higher frequency of daily snacking (p = 0.013 was positively associated with local-based food pattern. For Chinese adolescents, age (p < 0.001, PA levels (p < 0.001 and maternal education level (p = 0.035 showed positive associations with the healthy-based pattern, whereas high EatOut (p = 0.001 and fast food intakes (p = 0.001 were negatively associated. Higher weekly consumption of EatOut (p = 0.007, fast food (p = 0.023 and carbonated beverages (p = 0.023, and daily snacking practice (p = 0.004 were positively associated with higher Western-based food pattern, whereas age (p = 0.004 was inversely associated. Conclusion: This study showed that there were significant differences in dietary patterns and its association factors between Malay and Chinese adolescents. More importantly, these findings suggest that

    With aging, energy needs decrease, necessitating a more nutrient-dense diet to meet nutritional needs. To bridge this gap, the use of nutrient-dense foods, fortified foods, and dietary supplements can be important. This observational study aims to describe current micronutrient intakes of Dutch elderly and to identify the contribution of nutrient-dense foods, fortified foods, and dietary supplements to the intake of micronutrients that are often inadequately consumed in Dutch elderly. Data of 245 Dutch volunteers from the NU-AGE study aged 65 to 80 years were used. Dietary intake was assessed by means of 7-day food records, and dietary supplement use was recorded with an additional questionnaire. Information on fortified foods was obtained from the Dutch Food Composition Table 2011. Nutrient density of foods was evaluated using the Nutrient Rich Food 9.3 score. The percentages of participants not meeting their average requirement were high for vitamin D (99%), selenium (41%), and vitamin B6 (54%) based on conventional foods and also when taking into account fortified foods (98%, 41%, and 27%, respectively) and vitamin and mineral supplements (87%, 36%, and 20%, respectively). Conventional foods were the main source of vitamin D, vitamin B6, and selenium intake (42%, 45%, and 82%, respectively), followed by vitamin and mineral supplements (41%, 44%, and 18%) and fortified foods (17%, 11%, and 1%). Foods with the highest nutrient density contributed most to total vitamin B6 intake only. To optimize nutrient intakes of elderly, combinations of natural food sources, fortified foods, and dietary supplements should be considered. Copyright © 2016 The Authors. Published by Elsevier Inc.

    Food is the major route of human intake of toxic dioxin-like compounds (DLCs), which include PolyChlorinated Dibenzo-p-Dioxins (PCDDs), PolyChlorinated Dibenzo-p-Furans (PCDFs), and PolyChlorinated Biphenyls (PCBs). Approximately 95% of human DLCs exposure derives from food, with nearly 80% coming from food of animal origin. The DLCs levels in foodstuffs and the food consumption rate are essential to evaluate health risk posing to humans. The lack of DLCs levels in food increases the population's risk to DLCs exposure. The Department of Health, Taiwan has entrusted us to conduct a comprehensive monitoring program on PCDD/Fs levels in Taiwan food (not including plant origin) in 2001 and 2002, In 2003, the program has extended the analytes to include 12 WHO-PCBs. A total diet study (TDS) of DLCs intake from Taiwan food is, therefore, conducted for the first time. The DLCs concentrations in food of animal origin and the food consumption rate are collected. The average daily intake (ADI) and average weekly intake (AWI) of DLCs from food by Taiwan adults is determined.

    To date, there are no food frequency questionnaires that have been validated to assess nutrient intakes in pregnant women in Ireland. The present study aimed to assess the relative validity of a self-administered food frequency questionnaire during pregnancy. The food frequency questionnaire was administered once during pregnancy between 12 and 34 weeks. Participants also completed a 3-day food diary during each trimester of pregnancy (reference method) and intakes from both the food frequency questionnaire and the mean of the 3-day food diaries were compared in a sample of 130 participants from the control arm of an intervention study. Energy-adjusted Pearson's correlation coefficients ranged from 0.24 (riboflavin) to 0.59 (magnesium) and were all statistically significant (P food frequency questionnaire tended to report higher energy and nutrient intakes compared to the food diaries. On average, 74% of participants were classified into the same ± 1 quartile and 7% into opposing quartiles by the two methods. Overall, our food frequency questionnaire showed good relative validity. We conclude that a single administration of a food frequency questionnaire is a valid tool for ranking women in accordance with their nutrient intakes during pregnancy. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

Participants in the Supplemental Nutrition Assistance Program were eligible to receive a dollar-per-dollar match up to $10/wk in farmers' market incentives. The researchers used a pretest-posttest design to measure F&V intake and food security status of 54 adult participants before and after receiving farmers' market incentives. The 6-item Behavior Risk Factor Surveillance System questionnaire and US Household Food Security Survey Module were used to measure F&V intake and food security, respectively. Wilcoxon signed-rank test was used to compare scores of F&V intake. After receiving incentives, fewer individuals reported experiencing food insecurity-related behaviors. A significantly increased intake (P market incentive program was positively related to greater food security and intake of select vegetables among participants in the Supplemental Nutrition Assistance Program.

    The effects were studied of whole-body X-irradiation with sublethal (2.39 Gy) and medium lethal (5.74 Gy) doses on food intake by rats. The lower dose caused a temporary decrease in food intake, with a minimum of 63.3% of the control level on the 2nd day after irradiation. The decrease was statistically significant up to the 4th day after irradiation. No substantial changes were observed in the parameters of the circadian rhythm in food intake with the maximum on the 3rd day after irradiation, with only 8% of the initial value. The food intake was reduced until the 9th day after irradiation. The daily thythm of food intake was strongly disturbed during the first three days after irradiation, then restoring gradually and on the 9th day showing the original phasing and shape. The results obtained were in agreement with the assumed neural regulation mechanism of food intake and its circadian rhythm in the rat. (author). 5 figs., 12 refs

    Phoenixin, a recently discovered 20-amino acid peptide was implicated in reproduction. However, the expression in food intake-regulatory nuclei such as the paraventricular nucleus, the arcuate nucleus and the nucleus of the solitary tract suggests an implication of phoenixin in food intake regulation. Therefore, we investigated the effects of phoenixin-14, the shorter form of phoenixin, on food intake following intracerebroventricular (icv) and intraperitoneal (ip) injection in ad libitum fed male Sprague-Dawley rats. Phoenixin-14 injected icv (0.2, 1.7 or 15nmol/rat) during the light phase induced a dose-dependent increase of light phase food intake reaching significance at a minimum dose of 1.7 nmol/rat (+72%, pfood intake microstructure showed an icv phoenixin-14-induced increase in meal size (+51%), meal duration (+157%), time spent in meals (+182%) and eating rate (+123%), while inter-meal intervals (-42%) and the satiety ratio (-64%) were decreased compared to vehicle (pfood intake was observed (p>0.05). The light phase icv phoenixin-14-induced increase of water intake did not reach statistical significance compared to vehicle (+136%, p>0.05). The increase of food intake following icv phoenixin-14 was not associated with a significant alteration of grooming behavior (0.4-fold, p=0.377) or locomotion (6-fold, p=0.066) compared to vehicle. When injected ip at higher doses (0.6, 5nmol/kg or 45nmol/kg body weight) during the light phase, phoenixin-14 did not affect food intake (p>0.05). In summary, phoenixin-14 exerts a centrally-mediated orexigenic effect. Copyright © 2017 Elsevier Inc. All rights reserved.

    In this study, we aimed to explain the role of apelin-13 on body weight, food and water intake with serum leptin, ghrelin, neuropeptid Y (NPY) and peptid YY (PYY) levels in male rat. Thirty-two Sprague-Dawley male rats were used for the study. The rats were injected SP (0.9 %) intraperitoneally (i.p) in the control group and 30 (AP30), 100 (AP100) and 300 (AP300) µg/kg apelin-13 in the study groups, respectively, 10 min before the transition to dark period, for 10 days. During the experimental period, with light and dark periods of food and water intake, body weights were recorded in rats. Rats were euthanized and serum samples were obtained. In serum samples leptin, ghrelin, NPY and PYY levels were measured with specific ELISA kit. Apelin-13 was increased body weights in all three (AP30, AP100 and AP300) groups compared with the control group. AP100 and AP300 groups had increased food intake in the dark and the cumulative period, but in the light period food intake values were not significantly increased (p > 0.05). As for the value of water intake, compared with the control group, all dose of apelin-13 increased water intake during the dark and the cumulative period. There was no significant change in water intake in the light period. On the other hand, compared with the control group, serum leptin levels were found to increase in the groups administered 100 and 300 µg/kg of apelin-13 (p Ghrelin levels were found high in all groups treated with apelin-13. Serum levels of NPY decreased only in the 300 µg/kg apelin-13 treated group (p 0.05). Apelin-13 increases body weight in rats as well as food and water intake (dark and cumulative period). Additionally, ghrelin can mediate the orexigenic effect of apelin-13 in the regulation of food intake (Fig. 4, Ref. 37).

    Full Text Available Nicotine alters appetite and energy expenditure, leading to changes in body weight. While the exact mechanisms underlying these effects are not fully established, both central and peripheral involvement of the alpha-7 nicotinic acetylcholine receptor (α7nAChR has been suggested. Centrally, the α7nAChR modulates activity of hypothalamic neurons involved in food intake regulation, including proopiomelanocortin (POMC and neuropeptide Y (NPY. α7nAChRs also modulate glutamatergic and dopaminergic systems controlling reward processes that affect food intake. Additionally, α7nAChRs are important peripheral mediators of chronic inflammation, a key contributor to health problems in obesity. This review focuses on nicotinic cholinergic effects on eating behaviors, specifically those involving the α7nAChR, with the hypothesis that α7nAChR agonism leads to appetite suppression. Recent studies are highlighted that identify links between α7nAChR expression and obesity, insulin resistance, and diabetes and describe early findings showing an α7nAChR agonist to be associated with reduced weight gain in a mouse model of diabetes. Given these effects, the α7nAChR may be a useful therapeutic target for strategies to treat and manage obesity.

    While the average frequency of chewing and food intake have been reported before, a detailed description of the pattern of chewing and the cumulative intake of food over the course of a meal have not. In order to achieve this goal, video recording of the maxillary-mandibular region of women eating food from a plate was synchronized with video recording of the plate and computer recording of the weight-loss of the plate. Video recording of chewing correlated strongly with chewing identified by magnetic tracking of jaw displacement in a test with chewing gum at three different frequencies, thus ensuring the validity of video recording of chewing. Weight-loss data were corrected by convolution algorithms, validated against human correction, using sliding window filtering to correct errors with video events as reference points. By use of this method, women ate on average 264 g of food over 114 min, they took an average of 51 mouthfuls during the meal and displayed on average 794 chews with 15 chews per chewing sequence. The number of mouthfuls decreased and the duration of the pauses after each mouthful increased in the middle of the meal and these measures were then restored. The ratio between chewing sequences and subsequent pauses remained stable although the weight of each mouthful decreased by the end of the meal, a measure that is hypothesized to be reflected in a decelerated speed of eating. The method allows this hypothesis to be tested and its implication for clinical intervention to be examined. Copyright © 2011 Elsevier Inc. All rights reserved.

    We examined associations between fast-food intake and perceived and objective fast-food outlet exposure. Information from the Health Behaviours in School-aged Children Study was linked to fast-food outlets in seventy-five school neighbourhoods. We used multivariate multilevel logistic regression analyses to examine associations between at least weekly fast-food intake and perceived and objective fast-food outlet measures. Data represent 4642 adolescents (aged 11-15 years) in Denmark. Boys reporting two or more fast-food outlets had 34% higher odds consuming fast food at least weekly. We detected higher odds of at least weekly fast-food intake among 15-year-old 9th graders (ORall=1.74; 95% CI 1.40, 2.18; ORboys=2.20; 95% CI 1.66, 2.91; ORgirls=1.41; 95% CI 1.03, 1.92), Danish speakers (ORall=2.32; 95% CI 1.68, 3.19; ORboys=2.58; 95% CI 1.69, 3.93; ORgirls=2.37; 95% CI 1.46, 3.84) and those travelling 15 min or less to school (ORall=1.21; 95% CI 1.00, 1.46; ORgirls=1.44; 95% CI 1.08, 1.93) compared with 11-year-old 5th graders, non-Danish speakers and those with longer travel times. Boys from middle- (OR=1.28; 95% CI 1.00, 1.65) and girls from low-income families (OR=1.46; 95% CI 1.05, 2.04) had higher odds of at least weekly fast-food intake compared with those from high-income backgrounds. Girls attending schools with canteens (OR=1.47; 95% CI 1.00, 2.15) had higher odds of at least weekly fast-food intake than girls at schools without canteens. The present study demonstrates that perceived food outlets may impact fast-food intake in boys while proximity impacts intake in girls. Public health planning could target food environments that emphasize a better understanding of how adolescents use local resources.

    Low dietary fibre intake has been associated with poorer health outcomes, therefore having the ability to be able to quickly assess an individual's dietary fibre intake would prove useful in clinical practice and for research purposes. Current dietary assessment methods such as food records and food frequency questionnaires are time-consuming and burdensome, and there are presently no published short dietary fibre intake questionnaires that can quantify an individual's total habitual dietary fibre intake and classify individuals as low, moderate or high habitual dietary fibre consumers. Therefore, we aimed to develop and validate a habitual dietary fibre intake short food frequency questionnaire (DFI-FFQ) which can quickly and accurately classify individuals based on their habitual dietary fibre intake. In this study the DFI-FFQ was validated against the Monash University comprehensive nutrition assessment questionnaire (CNAQ). Fifty-two healthy, normal weight male (n = 17) and female (n = 35) participants, aged between 21 and 61 years, completed the DFI-FFQ twice and the CNAQ once. All eligible participants completed the study, however the data from 46% of the participants were excluded from analysis secondary to misreporting. The DFI-FFQ cannot accurately quantify total habitual dietary fibre intakes, however, it is a quick, valid and reproducible tool in classifying individuals based on their habitual dietary fibre intakes.

    To investigate the feasibility of Fabuless (previously called Olibra and Reducal) as a food ingredient for food intake and appetite reduction, by assessing the effects of food processing on efficacy. In total, 24 healthy volunteers (16 female, 8 male; age: 18-43 years; body mass index: 18-37 kg/m(2)) took part in a randomized, placebo-controlled, double-blinded, cross-over trial. Yoghurt-based meal replacement drinks (containing processed or unprocessed Fabuless, or a control fat) were followed by an ad libitum lunch and evening meal (dinner). Key outcome measures were energy intake and self-reported appetite ratings. Compared with control, only unprocessed Fabuless reduced subsequent energy intake, although only during dinner (P processed and unprocessed: 4.3, 3.9 and 4.2 MJ, respectively) and not during lunch (3.6, 3.7 and 3.6 MJ). Self-reported appetite scores did not differ between treatments. Although modest effects of unprocessed Fabuless were seen on food intake, but not on appetite, the ingredient was not robust to common food-manufacturing processes (thermal and shear processing). Claims on reduced food intake and appetite relating to this ingredient in food products are, therefore, only valid if functionality has been demonstrated after all relevant processing and storage steps.

    Nowadays India is undergoing an impressive economic growth accompanied by a very slow decline, almost stagnation, in malnutrition levels. In developing countries, studies on dietary patterns and their relationship with nutritional status are scarce. Over the years some nutritional studies have been performed to explore different types of food consumed in various Indian regions, among different social samples. The aim of the present paper is to review and describe trends in food and nutrition intake patterns in the different states of India. The review was carried out in PubMed, using the advanced research criteria: [food* OR ("meal pattern*") OR ("eating pattern*")] AND ("nutrient intake") AND India*. PubMed research gave back 84 results and out of these, 7 papers due to their focus on food intake and consumption levels in India have been included in this study. Food intake patterns showed that most of the Indians are vegetarians and that food items rich in micronutrients (pulses, other vegetables, fruits, nuts, oilseeds and animal foods) are generally consumed less frequently. Poor and monotonous cereals-based diet may promote inadequate nutrition intakes according to Recommended Daily Allowance (RDA) standards.

    The aim of study was to determine the intake of nitrites and nitrates in daily food rations of the students' group in 2008 using 3-day dietary food records method and literature mean values of nitrates and nitrites in food products. Intakes of these compounds were calculated and compared to acceptable daily intake (ADI). The average intake of nitrites was 1.7 mg NaNO2/per person/day (28.0% of ADI), nitrates 77.3 mg NaNO3/per person/day that means 25.4% of ADI. The largest nitrites food intake was noticed for meat products supplied 56.5% of nitrites and cereals (20%). Whereas vegetables and their products supplied 76.1% of nitrates: potatoes 17.1%, cabbage 15.5%, beetroots 13.7%. Calculated nitrites intake for men was 2.4 higher than for women. There were no significant differences of nitrates intake between men and women groups.

    A double-blind randomized crossover study was performed with nineteen normal-weight men to investigate the effect on subsequent ad libitum food intake of replacing 29 g sucrose with 29 g D-tagatose as sweetener to a breakfast meal. D-Tagatose is a malabsorbed stereoisomer of fructose with potential application as a bulk sweetener. Food intake was measured at lunch offered 4 h after the breakfast meal, during the afternoon with access to abundant snacks, and finally at a supper buffet 9 h after the breakfast. Energy intake at lunch and during the snacking period was similar after ingesting the two sugars, while it was 15% lower after ingesting D-tagatose than with sucrose at supper (P effects of unabsorbed D-tagatose causing distension of the gut might have mediated the acute appetite-suppressing effect. The present paper also refers to data from a preceding study in which we observed an increased self-reported energy intake after ingestion of D-tagatose compared with sucrose which, in fact, suggests a relative hyperphagic effect of D-tagatose. However, self-reported food intake may be biased by selective under-reporting and this subsequent study with a more controlled assessment of food intake was therefore conducted. This present study did not support any hyperphagic effect of D-tagatose, but rather suggests that D-tagatose may contribute to a reduced energy intake.

    Full Text Available Quercetin is a promising food component, which can prevent lifestyle related diseases. To understand the dietary intake of quercetin in the subjects of a population-based cohort study and in the Japanese population, we first determined the quercetin content in foods available in the market during June and July in or near a town in Hokkaido, Japan. Red leaf lettuce, asparagus, and onions contained high amounts of quercetin derivatives. We then estimated the daily quercetin intake by 570 residents aged 20–92 years old in the town using a food frequency questionnaire (FFQ. The average and median quercetin intakes were 16.2 and 15.5 mg day−1, respectively. The quercetin intakes by men were lower than those by women; the quercetin intakes showed a low correlation with age in both men and women. The estimated quercetin intake was similar during summer and winter. Quercetin was mainly ingested from onions and green tea, both in summer and in winter. Vegetables, such as asparagus, green pepper, tomatoes, and red leaf lettuce, were good sources of quercetin in summer. Our results will help to elucidate the association between quercetin intake and risks of lifestyle-related diseases by further prospective cohort study and establish healthy dietary requirements with the consumption of more physiologically useful components from foods.

    Two experiments were conducted to test a prediction of the arousal hypothesis that increased arousal will increase intake of less palatable and healthy foods. In both experiments, arousal was manipulated by adjusting the volume of a movie (soft, loud volume) while participants consumed foods. In Experiment 1, participants ate fresh (palatable) or stale (less palatable) popcorn during a 9-minute movie played at a soft or loud volume. Experiment 2 used the same procedures with healthier foods (carrot sticks and apple slices). Partial support for the arousal hypothesis in Experiment 1 showed that participants consumed more stale but not fresh popcorn in the loud (high arousal) versus soft (low arousal) volume group. These findings suggest that low but not high palatable foods are susceptible to manipulations of arousal. Consistent with this interpretation, Experiment 2 showed that high but not low environmental arousal increased intake of the fruits and vegetables, which are typically rated as lower in palatability compared to high fat foods. These results show that high arousal in an eating-typical environment increases intake of less palatable foods, and healthy foods (i.e., fruits and vegetables). Increasing the availability of healthier foods in a loud food environment can have a positive impact on increasing intake of fruits and vegetables in that environment.

    To examine the association of food insufficiency with dietary intake and eating and health behaviours. A cross-sectional study. Data were obtained from a secondary source, the Fifth Korea National Health and Nutrition Examination Survey (2010-2012). The sample size consisted of 15 603 adults over 19 years of age (8898 households). Significant differences in socio-economic factors were observed according to food insufficiency level (Pfood-insufficient group, but we found no association with fat intake. Regarding micronutrients, Ca, Fe, vitamin A, thiamin, riboflavin niacin and vitamin C intakes were negatively associated with food insufficiency level (P trendfood groups, such as meat, fish, eggs and beans, vegetables and fruits, was significantly lower as food insufficiency level decreased after controlling for all possible variables; food group consumption also differed by sex. Overall eating and health behaviours were poorer in the mildly and severely food-insufficient groups, who received more food assistance but less nutritional education. Our results showed that dietary intake as well as eating and health behaviours are adversely associated with food insufficiency. These findings suggest that specific strategies to help food-insufficient individuals should be developed in order to improve their dietary quality and health status.

    It has been shown repeatedly that impulsivity, obesity and food intake are related; obese people are more impulsive than lean people and impulsive people eat more than less impulsive people. The relation between impulsivity and food intake might be state dependent; hunger motivates food seeking behaviour and food consumption, especially of high caloric food. Difficulties to overrule automatic behavioural tendencies might make impulsive people more susceptible to the effects of hunger on food selection. Therefore, they are expected to increase their intake more than low impulsive people when feeling hungry. STUDY 1: Fifty-seven female participants were randomly assigned to a hunger or sated condition. Response inhibition (a measure of impulsivity) and food intake were measured. Results show that impulsive participants ate significantly more, but only when feeling hungry. STUDY 2: Ninety-four undergraduate students participated. Hunger, response inhibition and the purchase of food in a virtual supermarket were measured. The same interaction was found: impulsive participants bought most calories, especially from snack food, but only when feeling hungry. Hunger and impulsivity interact in their influence on consumption. These data suggest that reducing hunger during calorie restricting diets is important for successful weight loss, particularly for the impulsive dieters.

  12. Role of addiction and stress neurobiology on food intake and obesity.

    The US remains at the forefront of a global obesity epidemic with a significant negative impact on public health. While it is well known that a balance between energy intake and expenditure is homeostatically regulated to control weight, growing evidence points to multifactorial social, neurobehavioral and metabolic determinants of food intake that influence obesity risk. This review presents factors such as the ubiquitous presence of rewarding foods in the environment and increased salience of such foods that stimulate brain reward motivation and stress circuits to influence eating behaviors. These rewarding foods via conditioned and reinforcing effects stimulate not only metabolic, but also stress hormones, that, in turn, hijack the brain emotional (limbic) and motivational (striatal) pathways, to promote food craving and excessive food intake. Furthermore, the impact of high levels of stress and trauma and altered metabolic environment (e.g. higher weight, altered insulin sensitivity) on prefrontal cortical self-control processes that regulate emotional, motivational and visceral homeostatic mechanisms of food intake and obesity risk are also discussed. A heuristic framework is presented in which the interactive dynamic effects of neurobehavioral adaptations in metabolic, motivation and stress neurobiology may further support food craving, excessive food intake and weight gain in a complex feed-forward manner. Implications of such adaptations in brain addictive-motivational and stress pathways and their effects on excessive food intake and weight gain are discussed to highlight key questions that requires future research attention in order to better understand and address the growing obesity epidemic.

    Full Text Available We identified urinary polyphenol metabolite patterns by a novel algorithm that combines dimension reduction and variable selection methods to explain polyphenol-rich food intake, and compared their respective performance with that of single biomarkers in the European Prospective Investigation into Cancer and Nutrition (EPIC study. The study included 475 adults from four European countries (Germany, France, Italy, and Greece. Dietary intakes were assessed with 24-h dietary recalls (24-HDR and dietary questionnaires (DQ. Thirty-four polyphenols were measured by ultra-performance liquid chromatography–electrospray ionization-tandem mass spectrometry (UPLC-ESI-MS-MS in 24-h urine. Reduced rank regression-based variable importance in projection (RRR-VIP and least absolute shrinkage and selection operator (LASSO methods were used to select polyphenol metabolites. Reduced rank regression (RRR was then used to identify patterns in these metabolites, maximizing the explained variability in intake of pre-selected polyphenol-rich foods. The performance of RRR models was evaluated using internal cross-validation to control for over-optimistic findings from over-fitting. High performance was observed for explaining recent intake (24-HDR of red wine (r = 0.65; AUC = 89.1%, coffee (r = 0.51; AUC = 89.1%, and olives (r = 0.35; AUC = 82.2%. These metabolite patterns performed better or equally well compared to single polyphenol biomarkers. Neither metabolite patterns nor single biomarkers performed well in explaining habitual intake (as reported in the DQ of polyphenol-rich foods. This proposed strategy of biomarker pattern identification has the potential of expanding the currently still limited list of available dietary intake biomarkers.

    Quantity and quality of fatty acids (FA) in diet influence CVD risk. Consequently, health authorities promote recommended dietary intakes for FA, looking for optimal intakes in a primary prevention of CVD perspective. In parallel, a few data are available detailing intakes in national populations. The objective of the present study was to perform a large analysis combining the data of the French National Survey INCA 2 on food consumption performed in 2006 and 2007, and the nutritional content of food consumed in France updated in 2013 by the French Information Centre on Food Quality, to explore in details the FA intakes in French adults using the most recent available data. To compare the discrepancies in the observed intake levels with the French recommended levels, a weighted fat adherence score was built combining intakes of the different FA. Individual scores were computed in relation to official recommendations, and potential explanatory factors were identified. These data show that SFA intakes are persistently higher than national recommendations, combined with low intakes of MUFA and PUFA, particularly long-chain n-3 FA. Only 14·6 % of the French population met DHA intake recommendation, 7·8 % for EPA and 21·6 % for SFA. This situation remains unfavourable in terms of primary prevention of CVD. Consuming fish and other sources of n-3 FA, living in the south of France, being female, having a higher education level, and low alcohol consumption were associated with a healthier fat adherence score.

    Full Text Available Adequate intake of iodine is essential for proper thyroid function. Although dietary reference intakes for iodine have been established, iodine intake cannot be estimated due to the lack of data on iodine contents in foods. We aimed to determine if food group intakes can predict iodine status assessed by urinary iodine concentration (UIC from spot urine samples of 5967 US adults in the National Health and Nutrition Examination Survey (NHANES 2007–2012. From an in-person 24-h dietary recall, all foods consumed were aggregated into 12 main food groups using the individual food code of the US Department of Agriculture (USDA; dairy products, meat/poultry, fish/seaweed, eggs, legumes/nuts/seeds, breads, other grain products, fruits, vegetables, fats/oils, sugars/sweets, and beverages. Chi-square test, Spearman correlation, and multiple linear regression analyses were conducted to investigate the predictability of food group intakes in iodine status assessed by UIC. From the multiple linear regressions, the consumption of dairy products, eggs, and breads, and iodine-containing supplement use were positively associated with UIC, whereas beverage consumption was negatively associated with UIC. Among various food group intakes, dairy product intake was the most important determinant of iodine status in both US men and women. Subpopulation groups with a high risk of iodine deficiency may need nutritional education regarding the consumption of dairy products, eggs, and breads to maintain an adequate iodine status. Efforts toward a better understanding of iodine content in each food and a continued monitoring of iodine status within US adults are both warranted.

    Full Text Available Abstract Background Although general parenting styles and restrictive parental feeding practices have been associated with children's weight status, few studies have examined the association between feeding styles and proximal outcomes such as children's food intake, especially in multi-ethnic families with limited incomes. The purpose of this study was to evaluate the association of parental feeding styles and young children's evening food intake in a multiethnic sample of families in Head Start. Methods Participants were 715 Head Start children and their parents from Texas and Alabama representing three ethnic groups: African-American (43%, Hispanic (29%, and White (28%. The Caregivers Feeding Styles Questionnaire (Hughes was used to characterize authoritative, authoritarian (referent, indulgent or uninvolved feeding styles. Food intake in several food groups was calculated from 3 days of dietary recalls for the child for evening food intakes from 3 PM until bedtime. Results Compared to children of authoritarian parents, intakes of fruits, juice and vegetables were lowest among children of indulgent or uninvolved parents (1.77 ± 0.09 vs 1.45 ± 0.09 and 1.42 ± 0.11 cups as were intakes of dairy foods (0.84 ± 0.05 vs 0.67 ± 0.05 and 0.63+0.06 cups, respectively. Conclusion Findings suggest that permissive parent feeding styles like indulgent or uninvolved relate negatively to children's intake of nutrient-rich foods fruit, 100% fruit juice, vegetables and dairy foods from 3 PM until bedtime.

    Full Text Available Abstract Background Complementary feeding is currently recommended after six months of age, when the nutrients in breast milk alone are no longer adequate to support growth. Few studies have examined macro- and micro-nutrient intakes from complementary foods (CF only. Our purpose was to assess the sources and nutritional contribution of CF over the first year of life. Methods In July 2003, a cross-sectional survey was conducted on a nationally representative sample of mothers with infants aged three to 12 months. The survey was administered evenly across all regions of the country and included a four-day dietary record to assess infants' CF intakes in household (tablespoon measures (breast milk and formula intakes excluded. Records from 2,663 infants were analyzed for nutrient and CF food intake according to 12 categories. Mean daily intakes for infants at each month of age from CF were pooled and compared to the Dietary Reference Intakes for the respective age range. Results At three months of age, 83% of infants were already consuming infant cereals. Fruits and vegetables were among the most common foods consumed by infants at all ages, while meats were least common at all ages except 12 months. Macro- and micro-nutrient intakes from CF generally increased with age. All mean nutrient intakes, except vitamin D and iron, met CF recommendations at seven to 12 months. Conclusions Complementary foods were introduced earlier than recommended. Although mean nutrient intakes from CF at six to 12 months appear to be adequate among Canadian infants, further attention to iron and vitamin D intakes and sources may be warranted.

    Dietary aluminum (Al) intake by young children, children, youths, and adults in Japan was estimated using the market basket method. The Al content of food category (I–VII) samples for each age group was determined by inductively coupled plasma-atomic emission spectrometry (ICP-AES). The Al content in processed foods and unprocessed foods ranged from 0.40 to 21.7 mg/kg and from 0.32 to 0.54 mg/kg, respectively. For processed foods in all age groups, the Al content in food category VI samples, sugar and confections/savories, was the highest, followed by those in category II, cereals. The daily dietary Al intake from processed foods was much larger than that from unprocessed foods. The mean weekly percentages of the provisional tolerable weekly intake (PTWI, established by the joint FAO/WHO Expert Committee on Food Additives in 2011) from processed foods for all age groups are 43.1, 22.4, 17.6 and 15.1%, respectively. Only the highest consumer Al exposure value (>P95) of the young children group exceeded the PTWI. PMID:25473496

    To increase the protein intake of older adults, protein enrichment of familiar foods and drinks might be an effective and attractive alternative for oral nutritional supplements (ONS). We performed a pilot study to test whether these products could help institutionalized elderly to reach a protein intake of 1.2 gram per kg body weight per day (g/kg/d). Intervention study with one treatment group (no control group). Dietary assessment was done before and at the end of a 10-day intervention. Two care facilities in Gelderland, the Netherlands: a residential care home and a rehabilitation center. 22 elderly subjects (13 women, 9 men; mean age 83.0±9.4 years). We used a variety of newly developed protein enriched regular foods and drinks, including bread, soups, fruit juices, and instant mashed potatoes. Dietary intake was assessed on two consecutive days before and at the end of the intervention, using food records filled out by research assistants. Energy and macronutrient intake was calculated using the 2013 Dutch food composition database. Changes in protein intake were evaluated using paired t-tests. Protein intake increased by 11.8 g/d (P=0.003); from 0.96 to 1.14 g/kg/d (P=0.002). This increase is comparable to protein provided by one standard portion of ONS. The intake of energy and other macronutrients did not change significantly. At the end of the intervention more elderly reached a protein intake level of 1.2 g/kg/d than before (9 vs 4). Protein intake significantly increased during breakfast (+3.7 g) and during the evening (+2.2 g). Including familiar protein enriched foods and drinks in the menu helped to meet protein recommendations in institutionalized elderly.

    Food reinforcement (RRVfood) is related to increased energy intake, cross-sectionally related to obesity, and prospectively related to weight gain. The fat mass and obesity-associated (FTO) gene is related to elevated body mass index and increased energy intake. The primary purpose of the current study was to determine whether any of 68 FTO single nucleotide polymorphisms (SNPs) or a FTO risk score moderate the association between food reinforcement and energy or macronutrient intake. Energy and macronutrient intake was measured using a laboratory ad libitum snack food consumption task in 237 adults of varying BMI. Controlling for BMI, the relative reinforcing value of reading (RRVreading) and proportion of African ancestry, RRVfood predicted 14.2% of the variance in energy intake, as well as predicted carbohydrate, fat, protein and sugar intake. In individual analyses, six FTO SNPs (rs12921970, rs9936768, rs12446047, rs7199716, rs8049933 and rs11076022, spanning approximately 251kbp) moderated the relationship between RRVfood and energy intake to predict an additional 4.9-7.4% of variance in energy intake. We created an FTO risk score based on 5 FTO SNPs (rs9939609, rs8050136, rs3751812, rs1421085, and rs1121980) that are related to BMI in multiple studies. The FTO risk score did not increase variance accounted for beyond individual FTO SNPs. rs12921970 and rs12446047 served as moderators of the relationship between RRVfood and carbohydrate, fat, protein, and sugar intake. This study shows for the first time that the relationship between RRVfood and energy intake is moderated by FTO SNPs. Research is needed to understand how these processes interact to predict energy and macronutrient intake. Copyright © 2014 Elsevier Inc. All rights reserved.

    To describe availability and frequency of use of local snack-food outlets and determine whether reported use of these outlets was associated with dietary intakes. Data were cross-sectional. Availability and frequency of use of three types of local snack-food outlets were reported. Daily dietary intakes were based on the average of up to four 24 h dietary recalls. Multivariable linear regression models estimated average daily intakes of energy, sugar-sweetened beverages (SSB) and snack foods/sweets associated with use of outlets. Multi-site, observational cohort study in the USA, 2004-2006. Girls aged 6-8 years (n 1010). Weekly frequency of use of local snack-food outlets increased with number of available types of outlets. Girls with access to only one type of outlet reported consuming food/beverage items less frequently than girls with access to two or three types of outlets (P snack foods/sweets intakes increased with greater use of outlets. Girls who reported using outlets>1 to 3 times/week consumed 0·27 (95 % CI 0·13, 0·40) servings of SSB more daily than girls who reported no use. Girls who reported using outlets>3 times/week consumed 449·61 (95 % CI 134·93, 764·29) kJ, 0·43 (95 % CI 0·29, 0·58) servings of SSB and 0·38 (95 % CI 0·12, 0·65) servings of snack foods/sweets more daily than those who reported no use. Girls' frequency of use of local snack-food outlets increases with the number of available types of outlets and is associated with greater daily intakes of energy and servings of SSB and snack foods/sweets.

    We investigated whether eating lunch mindfully, in contrast to eating with distractions or no particular focus, reduces later snack intake and if this is related to a measure of meal memory. The design was between-subjects with three conditions. Twenty-nine female undergraduate students either ate a fixed lunch while (1) focusing on the sensory characteristics of the food as they ate (food focus group), (2) reading a newspaper article about food (food thoughts control group) or (3) in the absence of any secondary task (neutral control group). Cookie intake later that afternoon was measured as well as rated vividness of memory of the lunch. Participants ate significantly fewer cookies in the food focus group than in both the food thoughts control group or the neutral control group. Rated appetite before the snack session was lower in the food focus group than in the other two groups and rated vividness of lunch memory was higher. Rated vividness of lunch memory was negatively correlated with snack intake. These results suggest that enhancing meal memory by paying attention to food while eating can reduce later intake and are consistent with the suggestion that memory plays an important role in appetite control.

    Chronic tobacco use leads to nicotine addiction that is characterized by exaggerated urges to use the drug despite the accompanying negative health and socioeconomic burdens. Interestingly, nicotine users are found to be leaner than the general population. Review of the existing literature revealed that nicotine affects energy homeostasis and food consumption via altering the activity of neurons containing orexigenic and anorexigenic peptides in the brain. Hypothalamus is one of the critical brain areas that regulates energy balance via the action of these neuropeptides. The equilibrium between these two groups of peptides can be shifted by nicotine leading to decreased food intake and weight loss. The aim of this article is to review the existing literature on the effect of nicotine on food intake and energy homeostasis and report on the changes that nicotine brings about in the level of these peptides and their receptors that may explain changes in food intake and body weight induced by nicotine. Furthermore, we review the effect of nicotine on the hedonic aspect of food intake. Finally, we discuss the involvement of different subtypes of nicotinic acetylcholine receptors in the regulatory action of nicotine on food intake and energy homeostasis. © 2017 Society for Endocrinology.

    Working memory (WM) plays a critical role in cognitive control by shielding self-regulatory goals from distraction by desire-related thoughts and emotions. This study examined whether training WM increases self-regulation in overweight participants. It was hypothesized that WM training would decrease psychopathological eating-related thoughts, (over)consumption of food in response to emotions and external cues, food intake and body weight. Overweight participants (n = 50) performed 20-25 sessions of WM training or control/sham training. The dependent measures were self-reported eating-related psychopathology, self-reported emotional/external eating behavior, food intake during a bogus taste test, and body weight, assessed before training, immediately following training, and at one-month follow-up. Relative to control, WM training reduced psychopathological eating-related thoughts and emotional eating (but not external eating). These effects were still present at follow-up, one month later. Food intake and body weight did not show an overall effect of training, though WM training did reduce food intake among highly restrained participants. WM training effectively reduced eating-related thoughts, overeating in response to negative emotions, and food intake among participants with strong dietary restraint goals. Hence, these findings indicate that WM training may strengthen self-regulation by shielding dieting goals from distraction by unwanted eating-related thoughts and emotions.

    Full Text Available Diets rich in plant foods and lower in animal-based products have garnered increased attention among researchers, dietitians and health professionals in recent years for their potential to, not only improve health, but also to lessen the environmental impact. However, the potential effects of increasing plant-based foods at the expense of animal-based foods on macro- and micronutrient nutrient adequacy in the U.S. diet is unknown. In addition, dairy foods are consistently under consumed, thus the impact of increased dairy on nutrient adequacy is important to measure. Accordingly, the objective of this study was to use national survey data to model three different dietary scenarios to assess the effects of increasing plant-based foods or dairy foods on macronutrient intake and nutrient adequacy. Data from the National Health and Nutrition Examination Survey (NHANES 2007–2010 for persons two years and older (n = 17,387 were used in all the analyses. Comparisons were made of usual intake of macronutrients and shortfall nutrients of three dietary scenarios that increased intakes by 100%: (i plant-based foods; (ii protein-rich plant-based foods (i.e., legumes, nuts, seeds, soy; and (iii milk, cheese and yogurt. Scenarios (i and (ii had commensurate reductions in animal product intake. In both children (2–18 years and adults (≥19 years, the percent not meeting the Estimated Average Requirement (EAR decreased for vitamin C, magnesium, vitamin E, folate and iron when plant-based foods were increased. However the percent not meeting the EAR increased for calcium, protein, vitamin A, and vitamin D in this scenario. Doubling protein-rich plant-based foods had no effect on nutrient intake because they were consumed in very low quantities in the baseline diet. The dairy model reduced the percent not meeting the EAR for calcium, vitamin A, vitamin D, magnesium, and protein, while sodium and saturated fat levels increased. Our modeling shows that

    As nations seek to address obesity and diet-related chronic disease, understanding shifts in food intake over time is an imperative. However, quantifying intake of basic foods is not straightforward because of the diversity of raw and cooked wholefoods, processed foods and mixed dishes actually consumed. In this study, data from the Australian national nutrition surveys of 1995 and 2011, each involving more than 12,000 individuals and covering more than 4500 separate foods, were coherently disaggregated into basic foods, with cooking and processing factors applied where necessary. Although Australians are generally not eating in a manner consistent with national dietary guidelines, there have been several positive changes. Australians are eating more whole fruit, a greater diversity of vegetables, more beans, peas and pulses, less refined sugar, and they have increased their preference for brown and wholegrain cereals. Adult Australians have also increased their intake of nuts and seeds. Fruit juice consumption markedly declined, especially for younger Australians. Cocoa consumption increased and shifts in dairy product intake were mixed, reflecting one of several important differences between age and gender cohorts. This study sets the context for more detailed research at the level of specific foods to understand individual and household differences.

    The present study examined the association between food intake and endometrial cancer restricted to endometrial endometrioid adenocarcinoma (EEA) using a case-control study in Japanese women. One hundred sixty-one cases and 380 controls who completed a questionnaire regarding demographic, lifestyle, and food frequency questionnaire were analyzed. Odds ratio (OR) between selected food intakes and EEA were calculated by logistic regression analysis. After adjustment putative confounding factors, the higher intakes of vegetables [odds ratio (OR) = 0.47, 95% confidence interval (CI) = 0.26-0.83], peanuts (OR = 0.48, CI = 0.27-0.86), fish (OR = 0.52, CI = 0.29-0.93), boiled egg (OR = 0.24, CI = 0.33-0.92), instant noodles (OR = 1.94, CI = 1.12-3.34), instant food items (OR = 2.21, CI = 1.31-3.74), and deep-fried foods (OR = 2.87, CI = 1.58-5.21) were associated with a risk for EEA. The inverse association with a risk of EEA was also seen in higher intakes (g/1000 kcal) for vegetables (0.45, CI = 0.25-0.81) and fish (0.53, CI = 0.30-0.94) as compare to lower intake. Higher intake of vegetables, peanuts, fish, and boiled egg was associated with a reduced risk for EEA, whereas instant noodles, instant food items, and deep-fried foods was associated with an increased risk for EAA as compared to lower levels of intake.

    Epidemiological studies have suggested that flavonoids exhibit preventive effects on degenerative diseases. However, lack of sufficient data on flavonoid intake has limited evaluating the proposed effects in populations. Therefore, we aimed to estimate the total and individual flavonoid intakes among Korean adults and determine the major dietary sources of these flavonoids. We constructed a flavonoid database of common Korean foods, based on the food list reported in the 24-h recall of the Korea National Health and Nutrition Examination Survey (KNHANES) 2007-2012, using data from the Korea Functional Food Composition Table, US Department of Agriculture flavonoid database, Phenol-Explorer database and other analytical studies. This database, which covers 49 % of food items and 76 % of food intake, was linked with the 24-h recall data of 33 581 subjects aged ≥19 years in the KNHANES 2007-2012. The mean daily intake of total flavonoids in Korean adults was 318·0 mg/d, from proanthocyanidins (22·3%), flavonols (20·3%), isoflavones (18·1%), flavan-3-ols (16·2%), anthocyanidins (11·6%), flavanones (11·3%) and flavones (0·3%). The major contributing food groups to the flavonoid intake were fruits (54·4%), vegetables (20·5%), legumes and legume products (16·2%) and beverages and alcohols (3·1%), and the major contributing food items were apples (21·9%), mandarins (12·5%), tofu (11·5%), onions (9·6%) and grapes (9·0%). In the regression analysis, the consumption of legumes and legume products, vegetables and fruits predicted total flavonoid intake the most. The findings of this study could facilitate further investigation on the health benefits of flavonoids and provide the basic information for establishing recommended flavonoid intakes for Koreans.

    Eating difficulties are commonly present in medical and psychiatric settings. Some eating problems are resultant from fears about food consumption and can be conceptualized as anxiety disorders conditioned by perception of feared outcomes associated with eating and maintained by avoidance. The authors present a case in which a female patient with limited food intake is successfully treated with cognitive-behavioral therapy. Illness anxiety disorder and avoidant/restrictive food intake disorder, both newly included in DSM-V, are applied in this case. Copyright © 2015. Published by Elsevier Ltd.

    Folate is found naturally in foods or as synthetic folic acid in dietary supplements and fortified foods. Adequate periconceptional folic acid intake can prevent neural tube defects. Folate intake impacts blood folate concentration; however, the dose-response between natural food folate and blood folate concentrations has not been well described. We estimated this association among healthy females. A systematic literature review identified studies (1 1992-3 2014) with both natural food folate intake alone and blood folate concentration among females aged 12-49 years. Bayesian methods were used to estimate regression model parameters describing the association between natural food folate intake and subsequent blood folate concentration. Seven controlled trials and 29 observational studies met the inclusion criteria. For the six studies using microbiologic assay (MA) included in the meta-analysis, we estimate that a 6% (95% Credible Interval (CrI): 4%, 9%) increase in red blood cell (RBC) folate concentration and a 7% (95% CrI: 1%, 12%) increase in serum/plasma folate concentration can occur for every 10% increase in natural food folate intake. Using modeled results, we estimate that a natural food folate intake of ≥ 450 μg dietary folate equivalents (DFE)/day could achieve the lower bound of an RBC folate concentration (~ 1050 nmol/L) associated with the lowest risk of a neural tube defect. Natural food folate intake affects blood folate concentration and adequate intakes could help women achieve a RBC folate concentration associated with a risk of 6 neural tube defects/10,000 live births.

    Little is known about adolescents' non-core food intake in the UK and the eating context in which they consume non-core foods. The present study aimed to describe types of non-core foods consumed by British adolescents in total and across different eating contexts. A descriptive analysis, using cross-sectional data from food diaries. Non-core foods were classified based on cut-off points of fat and sugar from the Australian Guide to Healthy Eating. Eating context was defined as 'where' and 'with whom' adolescents consumed each food. Percentages of non-core energy were calculated for each food group in total and across eating contexts. A combined ranking was then created to account for each food's contribution to non-core energy intake and its popularity of consumption (percentage of consumers). The UK National Diet and Nutrition Survey 2008-2011. Adolescents across the UK aged 11-18 years (n 666). Non-core food comprised 39·5 % of total energy intake and was mostly 'Regular soft drinks', 'Crisps & savoury snacks', 'Chips & potato products', 'Chocolate' and 'Biscuits'. Adolescents ate 57·0 % and 51·3 % of non-core food at 'Eateries' or with 'Friends', compared with 33·2 % and 32·1 % at 'Home' or with 'Parents'. Persistent foods consumed across eating contexts were 'Regular soft drinks' and 'Chips & potato products'. Regular soft drinks contribute the most energy and are the most popular non-core food consumed by adolescents regardless of context, and represent a good target for interventions to reduce non-core food consumption.

    The United States is the largest refugee resettlement country in the world. Refugees may face health-related challenges after resettlement in the United States, including higher rates of chronic diseases due to problems such as language barriers and difficulty adapting to new food environments. However, reported refugee diet challenges varied, and no systematic examination has been reported. This study examined refugee food intake pre- and postresettlement in the United States and differences in intake across various refugee groups. We systematically reviewed relevant studies that reported on refugee food intake and adaptation to the US food environment. We searched PubMed for literature published between January 1985 and April 2015, including cross-sectional and prospective studies. Eighteen studies met inclusion criteria. Limited research has been conducted, and most studies were based on small convenience samples. In general, refugees increased meat and egg consumption after resettling in the United States. Changes in refugee intake of vegetables, fruits, and dairy products varied by socioeconomic status, food insecurity, past food deprivation experience, length of stay in the United States, region of origin, and age. South Asians were more likely to maintain traditional diets, and increased age was associated with more conservative and traditional diets. Despite the abundance of food in the United States, postresettlement refugees reported difficulty in finding familiar or healthy foods. More research with larger samples and follow-up data are needed to study how refugees adapt to the US food environment and what factors may influence their food- and health-related outcomes. The work could inform future interventions to promote healthy eating and living among refugees and help to reduce health disparities. PMID:28140324

  5. Effect of day-night cycle on distribution of food intake and economic choice among imposed food opportunities in mice.

    We have shown previously that mice given access to four discrete feeding opportunities (FOs) per day show a characteristic sequence of sizes across ordinal FOs. The purpose of the present experiments was to determine the relative contributions of external and internal factors on the sequencing of FO size. The external factors were the light:dark Zeitgeber and the cost of food, imposed via different fixed unit prices (FUP) in a closed operant economy, and the internal factors were signals relating to energy status including time since last food and weight loss. In the first experiment, mice were given 4 FOs spaced 4-h apart, but with the timing of the FOs relative to the Zeitgeber altered by a 4-h Zeitgeber advance or delay of the cycle. Food intake, and associated body weight, declined as price increased, but the temporal order of FO size was invariant within a Zeitgeber condition. The Zeitgeber advanced group showed clear evidence of a shift in meal sequence relating to the light:dark cycle. Thus, external factors seem to be a more important determinant of total intake and sequencing than internal factors. In the second experiment, mice were given the choice between continuous costly (CC) and intermittent inexpensive (II) food. II food was available for four-15min intervals every 4-h, and the timing of the 15min intervals was varied relative to the Zeitgeber cycle. In spite of a 20-fold difference in price between CC and II food, mice took approximately equal amounts from each, and all food intake took place during the dark phase. Mice consumed II food only if it was available during the dark phase. Food intake was strongly linked to the light:dark cycle, largely independent of food cost. Copyright © 2016 Elsevier Inc.

    Full Text Available Background: Dietary intake of macronutrient and foods is considered crucial to decrease the risk of diet-related non-communicable diseases. Methods: The aim of this study was to describe the intake of major food groups and macronutrients in a random sample of 1838 southern Italian adults. Results: No significant differences of macronutrient consumption between sexes were found. By contrast, younger individuals had significantly higher intake of animal protein than older ones. Men reported consuming significantly more total processed meats and less eggs than women; egg consumption significantly increased by age groups. Significantly lower intake of fruit in the younger age group compared to older ones was found. Various patterns of correlation between food groups were described. More than half of individuals reached the suggested recommendations for carbohydrate and fiber intake, and about two-thirds met the recommendations for total protein and cholesterol intake, while only a minority met for total fat intake. Total and plant protein, monounsaturated and omega-6 fatty acids, were significantly inversely related with BMI (body mass index, while trans fatty acids and cholesterol were directly correlated. A direct association with unprocessed meats and an inverse association with processed meats was also found. Conclusions: The overall findings suggest that relatively healthy dietary habits are common in southern Italy.

    Background: Preterm delivery represents a substantial problem in perinatal medicine worldwide. Current knowledge on potential influences of probiotics in food on pregnancy complications caused by microbes is limited. Objective: We hypothesized that intake of food with probiotics might reduce pregnancy complications caused by pathogenic microorganisms and, through this, reduce the risk of spontaneous preterm delivery. Design: This study was performed in the Norwegian Mother and Child Cohort on the basis of answers to a food-frequency questionnaire. We studied intake of milk-based products containing probiotic lactobacilli and spontaneous preterm delivery by using a prospective cohort study design (n = 950 cases and 17,938 controls) for the pregnancy outcome of spontaneous preterm delivery (<37 gestational weeks). Analyses were adjusted for the covariates of parity, maternal educational level, and physical activity. Results: Pregnancies that resulted in spontaneous preterm delivery were associated with any intake of milk-based probiotic products in an adjusted model [odds ratio (OR): 0.857; 95% CI: 0.741, 0.992]. By categorizing intake into none, low, and high intakes of the milk-based probiotic products, a significant association was observed for high intake (OR: 0.820; 95% CI: 0.681, 0.986). Conclusion: Women who reported habitual intake of probiotic dairy products had a reduced risk of spontaneous preterm delivery. PMID:20980489

    Full Text Available Abstract Background Cannabis sativa (also known as marijuana has been cultivated by man for more than 5,000 years. However, there was a rise in its use in the 20th century for recreational, religious or spiritual, and medicinal purposes. The main psychoactive constituent of cannabis, whose structure was identified in the 1960's, is Δ9-tetrahydrocannabinol. On the other hand, the discovery of cannabinoid receptors and their endogenous agonists took place only very recently. In fact, the first cannabinoid receptor (CB1 was cloned in 1990, followed 3 years later by the characterization of a second cannabinoid receptor (CB2. Since the 19th century, the use of cannabis has been reported to stimulate appetite and increase the consumption of sweet and tasty food, sometimes resulting in significant weight gain. The recent description of the endocannabinoid system, not only in the central nervous system but also in peripheral tissues, points to its involvement in the regulation of appetite, food intake and energy metabolism. Consequently, the pharmacological modulation of the over-activity of this system could be useful in the treatment of the metabolic syndrome. Conclusions The endocannabinoid system has important physiological functions not only in the central nervous system but also in peripheral tissues. The activation of central CB1 receptors, particularly in hypothalamic nuclei and in the limbic system, is involved in the regulation of feeding behavior, and especially in the control of the intake of palatable food. In the periphery, cannabinoid receptors are present in adipocytes, skeletal muscle, gastrointestinal tract and liver, modulating energy metabolism.

    The influence of parents versus friends on youths' eating behavior has not been directly compared, and little is known about the developmental effects of social influences on their eating behavior. The objective was to compare the effects of mothers and friends on children's and adolescents' energy intake from sandwiches and from healthy and unhealthy snacks and dessert foods. Twenty-three children (ages 5-7 y) and 27 adolescents (ages 13-15 y) ate a meal with their mother on one occasion and with a same-sex friend on another occasion. Male and female children consumed less energy from unhealthy snacks when in the presence of their mothers than when in the company of their friends. Conversely, female adolescents consumed less energy from unhealthy snacks and more energy from healthy snacks when they were with their friends than when with their mothers. Food selection is differentially influenced by the source of social influence and the age and sex of the child. Parents may act as an inhibitory influence on unhealthy eating for younger children. Adolescent girls may try to convey a good impression of healthy eating when eating with same-sex friends, but the eating habits of teenage boys are not as influenced by the social context. This trial is registered at clinicaltrials.gov as NCT00875576.

    Among the behaviors associated with food intake, exposure to television is particularly important given the number of adolescents exposed. Also, increased time spent watching television has been associated with physical inactivity and with less desirable dietary intake among adolescents. The aim of this study was to examine the association between television viewing and dietary intake among 13-y-old adolescents. A cross-sectional evaluation was carried out in the 2003-2004 school year, including adolescents born in 1990 and enrolled in the schools of Porto, Portugal. Time spent watching TV was collected by self-administered questionnaires and dietary intake was evaluated using a food frequency questionnaire. Included in the analysis were 1436 adolescents. Spending more than 120 min per day watching TV was significantly associated with higher intake of total fat and polyunsaturated fat and with lower intake of magnesium, in both sexes. Additionally, in girls, spending more than 120 min per day watching TV was associated with lower intake of complex carbohydrates, fiber, total vitamin A, folate, vitamin C, calcium, iron, phosphorus, and potassium. In boys, higher intake of saturated fat and cholesterol was found among those spending more time watching TV. We found that television viewing is associated with higher consumption of foods containing more fats and sugars and a lower consumption of fruits and vegetables. Consequently, adolescents who watched more television had a higher intake of total fat and polyunsaturated fat and a lower intake of minerals and vitamins. This dietary behavior among adolescents may have long-term health implications, not only limited to obesity. Copyright © 2013 Elsevier Inc. All rights reserved.

    Previous research has suggested that manipulations of plate size can have a direct impact on perception of food intake, measured by estimated fullness and intake. The present study, involving 570 individuals across Canada, China, Korea, and New Zealand, is the first empirical study to investigate cultural influences on perception of food portion as a function of plate size. The respondents viewed photographs of ten culturally diverse dishes presented on large (27 cm) and small (23 cm) plates, and then rated their estimated usual intake and expected fullness after consuming the dish, using 100-point visual analog scales. The data were analysed with a mixed-model ANCOVA controlling for individual BMI, liking and familiarity of the presented food. The results showed clear cultural differences: (1) manipulations of the plate size had no effect on the expected fullness or the estimated intake of the Chinese and Korean respondents, as opposed to significant effects in Canadians and New Zealanders (p Asian respondents. Overall, these findings, from a cultural perspective, support the notion that estimation of fullness and intake are learned through dining experiences, and highlight the importance of considering eating environments and contexts when assessing individual behaviours relating to food intake.

    The study of the somatotype and food intake among university students is important to carry out internal policies about the improvement of health and prevention of diseases. The aim of this study was to compare the somatotype, nutritional assessment and food intake of university sport and sedentary students. The sample were 1,299 university students (420 males and 879 females) from University of Valencia, during 2008-2009 and 2009-2010, who were evaluated for several anthropometric parameters, the somatotype and the nutritional and food intakes with a 7 day dietary diary. The somatotype was Endo-Mesomorph, Meso-Endomorph, Balanced Endomorph and Meso-Endomorph for sport and sedentary males, and sports and sedentary females, respectively. All groups had a high and low percentage of total calories in comparison with proteins plus lipids, and carbohydrates, respectively, as established in the nutritional objectives for the Spanish population. Low vitamin intakes, including E (in the sport males), A, D and E, folate and biotine (in the sedentary males) and A, D, E, folate and biotine (in the sport and sedentary females) were observed. All groups had a high intake of sodium and a deficit of potassium, calcium, iodine and magnesium. On the other hand, cereal groups were the most important in the energy dairy intake. Disequilibrium in macronutrients and micronutrients reflects the importance of developing food policies among University people to improve this situation. Copyright © 2011 Elsevier España, S.L.

    To examine knowledge of recommended daily calorie intake, use of calorie information, and sociodemographic correlates between knowledge and use. Population-based, random digit-dialed phone surveys. Canadian adults (n = 1,543) surveyed between October and December, 2012. Knowledge of recommended calorie intake and use of calorie information when purchasing food. Regression models, adjusting for sociodemographics and diet-related measures. Overall, 24% of participants correctly stated their recommended daily calorie intake; the majority (63%) underestimated it, whereas few (4%) overestimated it. Females, younger participants, those with a higher income and more education, and those who consumed fruits and vegetables at least 5 times daily were significantly more likely to state recommended intake correctly. Most respondents (82%) reported considering calories when selecting foods. Respondents considered calories more often if they were female, had a higher income and more education, perceived themselves to be overweight, were actively trying to control their weight, reported a healthier diet, or consumed fruits and vegetables at least 5 times daily. Although most Canadians reported using calorie information to guide their food choices, few knew their daily recommended calorie intake. To promote healthy weights, policy initiatives, including education regarding daily calorie intake and changes to the Nutrition Facts table, may help consumers make better choices about food.

    Adequate protein intake is important in preventing and treating undernutrition. Hospitalized older patients are recommended to consume 1.2-1.5 g of protein per kg body weight per day (g/kg/d) but most of them fail to do so. Therefore, we investigated whether a range of newly developed protein-enriched familiar foods and drinks were effective in increasing protein intake of hospitalized older patients. This randomized controlled trial involved 147 patients of ≥65 years (mean age: 78.5 ± 7.4 years). The control group (n = 80) received the standard energy and protein rich hospital menu. The intervention group (n = 67) received the same menu with various protein-enriched intervention products replacing regular products or added to the menu. Macronutrient intake on the fourth day of hospitalization, based on food ordering data, was compared between the two groups by using Independent T-tests and Mann Whitney U-tests. In the intervention group 30% of total protein was provided by the intervention products. The intervention group consumed 105.7 ± 34.2 g protein compared to 88.2 ± 24.4 g in the control group (p intervention group than in the control group reached a protein intake of 1.2 g/kg/d (79.1% vs 47.5%). Protein intake was significantly higher in the intervention group at breakfast, during the morning between breakfast and lunch, and at dinner. This study shows that providing protein-enriched familiar foods and drinks, as replacement of regular products or as additions to the hospital menu, better enables hospitalized older patients to reach protein intake recommendations.

    Full Text Available Very small but cumulated decreases in food intake may be sufficient to erase obesity over a period of years. We examine the effect of slight changes in the accessibility of different foods in a pay-by-weight-of-food salad bar in a cafeteria serving adults for the lunch period. Making a food slightly more difficult to reach (by varying its proximity by about 10 inches or changing the serving utensil (spoon or tongs modestly but reliably reduces intake, in the range of 8-16%. Given this effect, it is possible that making calorie-dense foods less accessible and low-calorie foods more accessible over an extended period of time would result in significant weight loss.

    Many programs aim to alleviate vitamin A deficiency. Biofortification is an approach to improve provitamin A carotenoid concentrations of staple crops in some developing countries. In rural Zambia, maize accounts for the majority of energy intake. Provitamin A-biofortified (orange) maize has been released in Zambia. This study quantified food intake of Zambian children from records collected in a feeding trial in 2012 in order to compare adoption of orange maize and a new vegetable (green beans) with white maize and traditional foods. One hundred thirty-six children with a mean age of 71.5 +/- 6.9 months were fed three meals a day for 6 days a week for 15 weeks at four feeding centers. Breakfast consisted of maize porridge, and lunch and dinner were stiff porridge (nshima) with various side dishes (relishes). There were three treatment groups, which received orange maize and placebo oil, white maize and placebo oil, or white maize and a daily vitamin A supplement. Food was weighed before and after consumption. Nutritionists were trained to interview the children's caregivers about the previous day's intake using dietary recalls. Nine dietary recalls for each child were recorded and analyzed. Total food intake did not differ among the groups (p = .31) and energy intakes on Sundays (kcal) were below recommendations. Nshima intake was lower in the orange-maize group (p = .008), largely due to a genotype effect. Intakes of relish, green bean, and porridge did not differ among the groups (p > .19). Dietary recalls revealed that children living in sites closer to the main road consumed more on Sundays than children living about 8 km from the main road, but less in the evenings when children were off site. The intakes of energy of these Zambian children were low. Implementation and adoption of new and biofortified foods is possible with promotion.

    Aim. To determine whether food allergy affects overall dietary intake and food choices in Cypriot primary school children. Methods. As part of the first epidemiological study in Cyprus on food allergy in primary school children, two 24-hour recalls (one from a week and one from a weekend day) of twenty-eight food allergic children (21 girls) and thirty healthy children (20 girls) aged 6-11 years old, were analysed and compared regarding their macro- and micronutrient content, food choices and meal distribution. Results. Significant differences between the two subgroups of children were estimated regarding the total energy intake and macronutrients, where food allergic children were found to consume in lower quantities, as well as for calcium, niacin, fiber and vitamin E. Food allergic children were also found to avoid combining foods from the various food groups in their meals, and to prefer specific food products from each category, whereas they consumed higher amounts of sugar and fructose. Conclusion. Food allergy in Cypriot food allergic children impacts on both the quality and quantity of food choices, probably due to lack of nutritional education regarding proper elimination diet and alternative nutrient sources.

    This study examined the relationships among smoking status and total and specific types of food cravings (i.e., high-fats, sweets, fast-food fats, and complex carbohydrates/starches) and the influence of demographic, clinical, and psychological factors on this relationship. Seven-hundred and twelve adults completed measures of food cravings, dietary intake, and smoking history. Heights and weights were measured. Data were analyzed using univariate and multivariate analyses while adjusting for demographic, clinical, and psychological covariates. Compared to never smokers, current smokers reported more frequent cravings for high-fat foods and fast-food fats, after controlling for depression, stress, BMI and demographic factors. Current smokers also reported consuming more high-fat foods and fast-food fats. The association between cigarette smoking and total food craving was no longer significant after accounting for depression and stress, suggesting that depression and stress may account for the relationship between smoking and total food craving. Smoking did not moderate the relationship between food cravings and food intake. Nicotine dependence was positively correlated with the frequency of general food cravings and cravings for high fats, sweets, and carbohydrates/starches. Cigarette smokers, and especially those with higher nicotine dependence, may have greater difficulties in addressing food craving and changing eating habits, particularly in the context of depression and stress.

  20. Bioinformatics approaches for identifying new therapeutic bioactive peptides in food

    Full Text Available ABSTRACT:The traditional methods for mining foods for bioactive peptides are tedious and long. Similar to the drug industry, the length of time to identify and deliver a commercial health ingredient that reduces disease symptoms can take anything between 5 to 10 years. Reducing this time and effort is crucial in order to create new commercially viable products with clear and important health benefits. In the past few years, bioinformatics, the science that brings together fast computational biology, and efficient genome mining, is appearing as the long awaited solution to this problem. By quickly mining food genomes for characteristics of certain food therapeutic ingredients, researchers can potentially find new ones in a matter of a few weeks. Yet, surprisingly, very little success has been achieved so far using bioinformatics in mining for food bioactives.The absence of food specific bioinformatic mining tools, the slow integration of both experimental mining and bioinformatics, and the important difference between different experimental platforms are some of the reasons for the slow progress of bioinformatics in the field of functional food and more specifically in bioactive peptide discovery.In this paper I discuss some methods that could be easily translated, using a rational peptide bioinformatics design, to food bioactive peptide mining. I highlight the need for an integrated food peptide database. I also discuss how to better integrate experimental work with bioinformatics in order to improve the mining of food for bioactive peptides, therefore achieving a higher success rates.

  1. The Immediate and Delayed Effects of TV: Impacts of Gender and Processed-Food Intake History

    Full Text Available Eating while watching TV has generally been found to increase both immediate and delayed energy intake. Here we examine two factors – gender and habitual processed-food intake – that may moderate these effects. Participants [n = 153; 95 women, 58 men; Mage = 19.7 (SD = 2.9; MBMI = 22.4 (SD = 3.1] ate an ad libitum snack either with or without TV, followed around 1 h later by lunch. There was an interaction between TV and gender for both meals. Women tended to consume more snack food in the TV condition, with men consuming more in the no-TV condition. Participants who habitually consumed more processed food also ate more snacks, independent of any other variable, including rated liking. At lunch, men who had earlier snacked with TV ate more than men who had snacked without TV, but this effect was not evident in women. On memory recall, all participants underestimated how much snack food they had eaten, and this was a function of how much they had actually consumed, with greater error only predicted by greater consumption. The results indicate that the effects of TV on eating can vary with gender and that processed-food history can predict snack food intake. While previous findings suggest memory of prior-intake may be impaired by eating while watching TV, the current results suggest this is not necessarily because of TV per se, but because people sometimes consume more food under such conditions.

    This research examined the effects of both episodic memory and episodic future thinking (EFT) on snack food intake. In Study 1, female participants (n = 158) were asked to recall their lunch from earlier in the day, to think about the dinner they planned to have later in the day, or to think about a non-food activity before taking part in a cookie taste test. Participants who recalled their lunch or who thought about their dinner ate less than did participants who thought about non-food activities. These effects were not explained by group differences in the hedonic value of the food. Study 2 examined whether the suppression effect observed in Study 1 was driven by a general health consciousness. Female participants (n = 74) were asked to think about their past or future exercise (or a non-exercise activity), but thinking about exercise had no impact on participants' cookie consumption. Overall, both thinking about past food intake and imagining future food intake had the same suppression effect on participants' current food intake, but further research is needed to determine the underlying mechanism.

    Dietary fats could affect glucose metabolism and obesity development and, thereby, may have a crucial role in the cause of type 2 diabetes (T2D). Studies indicated that replacing saturated with unsaturated fats might be favorable, and plant foods might be a better choice than animal foods. Nevertheless, epidemiologic studies suggested that dairy foods are protective. We hypothesized that, by examining dietary fat and its food sources classified according to fat type and fat content, some clarification regarding the role of dietary fat in T2D incidence could be provided. A total of 26,930 individuals (61% women), aged 45-74 y, from the Malmö Diet and Cancer cohort were included in the study. Dietary data were collected by using a modified diet-history method. During 14 y of follow-up, 2860 incident T2D cases were identified. Total intake of high-fat dairy products (regular-fat alternatives) was inversely associated with incident T2D (HR for highest compared with lowest quintiles: 0.77; 95% CI: 0.68, 0.87; P-trend fat fermented milk (P-trend fat dairy products was associated with increased risk, but this association disappeared when low- and high-fat dairy were mutually adjusted (P-trend = 0.18).

    A majority of Americans consume beverages and discretionary foods-foods that are typically low in nutrient value but high in sugar, sodium, fats, and cholesterol-as part of their daily diet, which profoundly impacts their energy balance and nutritional status. This study examined consumption of different types of beverages in relation to discretionary food intake and diet quality among US adults. Nationally representative sample of 22,513 adults from the National Health and Nutrition Examination Survey 2003 to 2012 waves were analyzed. The discretionary food category identifies energy-dense, nutrient-poor food products that do not necessarily provide essential nutrients that the human body needs, but can add variety. First-difference estimator addressed confounding bias from time-invariant unobservables (eg, eating habits, taste preferences) by using within-individual variations in diet and beverage consumption between 2 nonconsecutive 24-hour dietary recalls. Approximately 21.7%, 42.9%, 52.8%, 26.3%, and 22.2% of study participants consumed diet beverage, sugar-sweetened beverage (SSB), coffee, tea, and alcohol, respectively, and 90.1% consumed discretionary foods on any given day. Across beverage types, alcohol (384.8 kcal) and SSB (226.2 kcal) consumption was associated with the largest increase in daily total calorie intake; coffee (60.7 kcal) and diet-beverage (48.8 kcal) consumption was associated with the largest increase in daily calorie intake from discretionary foods, and SSB consumption was associated with the largest reduction in daily overall diet quality measured by the Healthy Eating Index 2010. The impact of beverage consumption on daily calorie intake (overall and from discretionary foods) and diet quality differed across individual sociodemographics and body-weight status. The incremental daily calorie intake from discretionary foods associated with diet-beverage consumption was highest in obese adults, and that associated with SSB was highest in

    Substantial number of elderly people suffer from poor mastication, which is considered to have a detrimental effect on their dietary habits. However, the association between mastication and diet is far from conclusive. The objective of this systematic review was to assess the association of mastication with food and nutrient intake in the community dwelling elderly. We searched the PubMed, Web of Science, Cochrane Library, and Scirus databases to obtain information on the epidemiological studies in this research area. The included publications were analyzed for study design, main conclusions, and strength of evidence. A comprehensive quality assessment of all the included studies (28 cross-sectional and 7 intervention studies) was performed. In 22 of the 28 cross-sectional studies, elderly persons with better mastication and dentition reported significantly higher consumption of foods and intake of some nutrients than those with poorer oral health; however, the remaining studies showed no such differences. Five of the 7 intervention studies with an intervention involving the provision of new prostheses did not show significant improvement in food and/or nutrient intake. These discrepant findings suggest that masticatory ability explains only part of the variance in food and nutrient intake of the elderly. Two intervention studies with the combination of prosthetic treatment and dietary intervention produced changes in intake of foods such as fruits and vegetables.

    Cold exposure and diet dilution which stimulate food intake of normal rats lessened depressions of food intake and growth induced by dietary GABA. During a 3-day adaptation to the cold, rats fed a diet containing 4.5% GABA lost weight; thereafter, food intake and growth rate differed little from those of cold control rats and were usually greater than those of normal rats fed GABA. Hepatic GABA-aminotransferase activity of cold-exposed rats fed the GABA diet increased to about twice that of normal control rats. Rats fed a control diet diluted by half with cellulose ate 50% more of this diet than of the undiluted diet but gained only 20% less weight. Rats ate twice as much of a diluted, 9% GABA diet as of an undiluted, 4.5% GABA diet (thus doubling their GABA intake) and gained three times as much weight. A novel food (condensed milk) barely lessened the adverse responses to GABA. These results show that conditions requiring rats to increase their food intake in order to maintain body weight can also increase their acceptance of a diet high in GABA.

    Full Text Available Abstract Background A growing body of literature links nutrition to mood, especially in epidemiological surveys, but there is little information characterizing food intake in people with diagnosed mood disorders. Methods Food intake obtained from 3-day food records was evaluated in 97 adults with mood disorders, whose diagnoses were confirmed in structured interviews. Information from a population nutrition survey, national guidelines for nutritional intakes (Eating Well with Canada's Food Guide and North American dietary guidelines (Dietary Reference Intakes was utilized to evaluate the quality of their food intake. Results Compared to the regional nutrition survey data and national guidelines, a greater proportion of study participants consumed fewer of the recommended servings of grains (p p p p p p 5.2 and ≤ 6.2 mmol/L and 21% had hypercholesterolemia (> 6.2 mmol/L. Conclusions Much research has proposed multiple ways in which healthier diets may exert protective effects on mental health. The results of this study suggest that adults with mood disorders could benefit from nutritional interventions to improve diet quality.

    There is considerable anecdotal and some scientific evidence that stress triggers eating behavior, but underlying physiological mechanisms remain uncertain. The hypothalamic-pituitary-adrenal (HPA) axis is a key mediator of physiological stress responses and may play a role in the link between stress and food intake. Cortisol responses to laboratory stressors predict consumption but it is unclear whether such responses mark a vulnerability to stress-related eating or whether cortisol directly stimulates eating in humans. We infused healthy adults with corticotropin-releasing hormone (CRH) at a dose that is subjectively undetectable but elicits a robust endogenous cortisol response, and measured subsequent intake of snack foods, allowing analysis of HPA reactivity effects on food intake without the complex psychological effects of a stress paradigm. CRH elevated cortisol levels relative to placebo but did not impact subjective anxious distress. Subjects ate more following CRH than following placebo and peak cortisol response to CRH was strongly related to both caloric intake and total consumption. These data show that HPA axis reactivity to pharmacological stimulation predicts subsequent food intake and suggest that cortisol itself may directly stimulate food consumption in humans. Understanding the physiological mechanisms that underlie stress-related eating may prove useful in efforts to attack the public health crises created by obesity. Copyright 2009 Elsevier Ltd.

    This study examined the potential moderating role of attentional bias (i.e., gaze duration, number of fixations, latency of initial fixation) in the effect of advergames promoting energy-dense snacks on children's snack intake. A randomized between-subject design was conducted with 92 children who played an advergame that promoted either energy-dense snacks or nonfood products. Eye movements and reaction times to food and nonfood cues were recorded to assess attentional bias during playtime using eye-tracking methods. Children could eat freely after playing the game. The results showed that playing an advergame containing food cues increased total intake. Furthermore, children with a higher gaze duration for the food cues ate more of the advertised snacks. In addition, children with a faster latency of initial fixation to the food cues ate more in total and ate more of the advertised snacks. The number of fixations on the food cues did not increase actual snack intake. Food advertisements are designed to grab attention, and this study shows that the extent to which a child's attention is directed to a food cue increases the effect of the advertisement.

    Research has shown that animals and humans habituate on a variety of behavioral and physiological responses to repeated presentations of food cues, and habituation is related to amount of food consumed and cessation of eating. The purpose of this article is to provide an overview of experimental paradigms used to study habituation, integrate a…

  13. Overconsumption of Energy and Excessive Discretionary Food Intake Inflates Dietary Greenhouse Gas Emissions in Australia

    Full Text Available Population dietary guidelines have started to include information about the environmental impacts of food choices, but more quantifiable evidence is needed, particularly about the impacts associated with discretionary foods. This paper utilised the 2011–2012 Australian Health Survey food intake data along with a highly disaggregated input–output model to estimate the greenhouse gas emissions (GHGe of Australians’ dietary intake, and compare current patterns of eating which vary in diet quality and GHGe to the recommended diet. The average dietary GHGe were 18.72 ± 12.06 and 13.73 ± 8.72 kg CO2e/day for male and female adults, respectively. The correlation between total energy and GHGe was r = 0.54 (p < 0.001. Core foods contributed 68.4% and discretionary foods 29.4%. Within core foods, fresh meat and alternatives (33.9% was the greatest contributor. The modelling of current dietary patterns showed the contribution of discretionary foods to GHGe was 121% greater in the average diet and 307% greater in the “lower quality, higher GHGe” diet compared to the recommended diet. Reducing discretionary food intake would allow for small increases in emissions from core foods (in particular vegetables, dairy and grains, thereby providing a nutritional benefit at little environmental expense. Public health messages that promote healthy eating, eating to one’s energy needs and improved diet quality will also contribute to lowering GHGe.

    Bisphenol A (BPA) is a high-volume, synthetic compound found in epoxy resins and plastics used in food packaging. Food is believed to be a major source of BPA intake. In this study, we measured the concentration of BPA in convenience samplings of foodstuffs purchased in Dallas, Texas. Sampling entailed collection of 204 samples of fresh, frozen, and canned foods in two rounds in 2010. BPA was positive in 73% of the canned food samples, while it was found in only 7% of non-canned foods at low ...

  15. [The effect of food intake on drug action].

    Interactions between medicaments and food are only incompletely documented--despite their frequent occurrence. Food can influence the effect of medicaments in a variety of ways: the effect of the medicament can be delayed or weakened; in some cases the effect may also be increased. The interactions between the kinetics of medicaments and food are described in the present survey. The absorption conditions in the stomach and small intestine are influenced physiologically and chemically by food. In very rare cases the elimination of active ingredients too can be modified by the quality and quantity of the food. Detailed knowledge about the physical-chemical properties of the medicaments used help to optimize the pharmacotherapy in the individual case. For the patient, the easiest suggestion to follow would be to take the medicaments with plenty of water and always at the same time.

  16. Access to food outlets and children's nutritional intake in urban China: a difference-in-difference analysis.

    In recent years supermarkets and fast food restaurants have been replacing those "wet markets" of independent vendors as the major food sources in urban China. Yet how these food outlets relate to children's nutritional intake remains largely unexplored. Using a longitudinal survey of households and communities in China, this study examines the effect of the urban built food environment (density of wet markets, density of supermarkets, and density of fast food restaurants) on children's nutritional intake (daily caloric intake, daily carbohydrate intake, daily protein intake, and daily fat intake). Children aged 6-18 (n = 185) living in cities were followed from 2004 to 2006, and difference-in-difference models are used to address the potential issue of omitted variable bias. Results suggest that the density of wet markets, rather than that of supermarkets, positively predicts children's four dimensions of nutritional intake. In the caloric intake model and the fat intake model, the positive effect of neighborhood wet market density on children's nutritional intake is stronger with children from households of lower income. With their cheaper prices and/or fresher food supply, wet markets are likely to contribute a substantial amount of nutritional intake for children living nearby, especially those in households with lower socioeconomic status. For health officials and urban planners, this study signals a sign of warning as wet markets are disappearing from urban China's food environment.

    Modifications of food intake by astronauts during long-duration spaceflights have been observed. Various psychological stress factors, such as isolation, confinement, constrained community and boredom, are thought to play a role in this phenomenon. For this reason it was decided to include a nutritional investigation in the EXEMSI simulation study, in which four crew members (1 female and 3 males) were isolated and confined for 60 days in a space station-like environment. The Food and Nutritional Management System, developed for this experiment, provided on-line analysis of all available foods in terms of their nutrient content (macronutrients, water, minerals, vitamins). It permitted to keep an accurate record of the daily food intake of each crew member. The system has been shown to be a powerful tool for future missions, either simulations or actual spaceflights. It permits optimal management of food and eating on board, and offers the possibility of online analysis of the nutritional status of the crew. It can provide readily usable data for future analysis of nutritional variables in relation to other physiological and metabolic parameters. It could also supply a periodic feedback to the subject for the purpose of adjusting food intake. Eating and nutrition during the experiment were not a problem, but a pleasure, and therefore played an important role in its success. Confinement and isolation apparently had no effect on either the eating habits or the nutritional status of the crew members. The good food rather helped to decrease the potentially induced stress by providing daily periods of pleasure and of social activities. Detailed analysis of food intake showed erratic eating patterns, both before and during the experiment. However, the weekly averages of macro- and micronutrient intakes were in the normal range, except for vitamins B1 and B6 that were rather low and showed the need for supplements. Food appreciation was assessed by daily questionnaires

    to provide information and data on food and fluid intake of free-living elderly aged of 81-86 years old residing in the south of France. using standardised methods data were collected from a random sample born between 1913 and 1918. The French study protocol again included data collection on dietary intake using a standardised modified dietary history consisting of a food frequency list and a 3-day estimated dietary record. Total dietary intake was generally low as compared to the recommended daily intake for elderly subjects. This descriptive part of the SENECA study gives the opportunity to have information on this growing segment of the population. These results should help to adapt the dietary guidelines for this category of the population.

    The aim of the CHANCE project is to develop novel and affordable nutritious foods to optimize the diet and reduce the risk of diet-related diseases among groups at risk of poverty (ROP). This paper describes the methodology used in the two initial steps to accomplish the project's objective as follows: 1. a literature review of existing data and 2. an identification of ROP groups with which to design and perform the CHANCE nutritional survey, which will supply new data that is useful for formulating the new CHANCE food. Based on the literature review, a low intake of fruit and vegetables, whole grain products, fish, energy, fiber, vitamins B1, B2, B3, B6, B12 and C, folate, calcium, magnesium, iron, potassium and zinc and a high intake of starchy foods, processed meat and sodium were apparent. However, the available data appeared fragmented because of the different methodologies used in the studies. A more global vision of the main nutritional problems that are present among low-income people in Europe is needed, and the first step to achieve this goal is the use of common criteria to define the risk of poverty. The scoring system described here represents novel criteria for defining at-risk-of-poverty groups not only in the CHANCE-participating countries but also all over Europe.

    It has been suggested that access to high caloric food attenuates stress response. The present paper investigates whether access to commercial chow enriched with glucose and fat, here referred to as comfort food alters behavioral, metabolic, and hormonal parameters of rats submitted to three daily sessions of foot-shock stress. Food intake, anxiety-like behaviors, and serum levels of insulin, leptin, corticosterone, glucose and triglycerides were determined. The rats submitted to stress decreased the intake of commercial chow, but kept unaltered the intake of comfort food. During the elevated plus maze (EPM) test, stressed rats increased the number of head dipping, entries into the open arms, as well as the time spent there, and decreased the number of stretched-attend posture and risk assessment. These effects of stress were independent of the type of food consumed. Non-stressed rats ingesting comfort food decreased risk assessment as well. Stress and comfort food increased time spent in the center of the open field and delayed the first crossing to a new quadrant. Stress increased the plasma level of glucose and insulin, and reduced triglycerides, although consumption of comfort food increases glucose, triglyceride and leptin levels; no effect on leptin level was associated to stress. The stress induced increase in serum corticosterone was attenuated when rats had access to comfort food. It was concluded that foot-shock stress has an anorexigenic effect that is independent of leptin and prevented upon access to comfort food. Foot-shock stress also has an anxiolytic effect that is potentiated by the ingestion of comfort food and that is evidenced by both EPM and open field tests. Copyright © 2011 Elsevier Inc.

    Inadequate energy and protein intake leads to malnutrition; a clinical disease not without consequence post acute hip fracture. Data detailing malnutrition prevalence, incidence, and intake adequacy varies widely in this patient population. The limited success of reported interventional strategies may result from poorly defined diagnostic criteria, failure to address root causes of inadequate intake, or errors associated with selection bias. This pragmatic study used a sequential, explanatory mixed methods design to identify malnutrition aetiology, prevalence, incidence, intake adequacy, and barriers to intake in a representative sample of 44 acute hip fracture patients (73% female; mean age, 81.7 ± 10.8 years). On admission, malnutrition prevalence was 52.2%. Energy and protein requirements were only met twice in 58 weighed 24 h food records. Mean daily patient energy intake was 2957 kJ (50.9 ± 36.1 kJ·kg(-1)) and mean protein intake was 22.8 g (0.6 ± 0.46 g·kg(-1)). This contributed to a further in-patient malnutrition incidence of 11%. Barriers to intake included patient perceptions that malnutrition and (or) inadequate intake were not a problem, as well as patient and clinician perceptions that treatment for malnutrition was not a priority. Malnutrition needs to be treated as a disease not without consequence, and food should be considered as a medicine after acute hip fracture.

    We developed a food frequency questionnaire (FFQ) designed to measure the dietary practices of adult Nepalese. The present study examined the validity and reproducibility of the FFQ. To evaluate the reproducibility of the FFQ, 116 subjects completed two 115-item FFQ across a four-month interval. Six 24-h dietary recalls were collected (1 each month) to assess the validity of the FFQ. Seven major food groups and 23 subgroups were clustered from the FFQ based on macronutrient composition. Spearman correlation coefficients evaluating reproducibility for all food groups were greater than 0.5, with the exceptions of oil. The correlations varied from 0.41 (oil) to 0.81 (vegetables). All crude spearman coefficients for validity were greater than 0.5 except for dairy products, pizzas/pastas and sausage/burgers. The FFQ was found to be reliable and valid for ranking the intake of food groups for Nepalese dietary intake.

    Phytosterols are well-known for their cholesterol-lowering effects, and the structures and forms of phytosterols affect their bioactivity. We aimed to illustrate the phytosterol profiles in common foods and estimate their natural intake in five geographical regions and among different age groups in China. In total, 12 phytosterols in free and esterified forms of 119 foods from five regions across China were examined using gas chromatography-mass spectrometry. Then, the dietary intake of phytosterols was calculated combined with the dietary foods intake data of Chinese people. The total phytosterol content was highest in vegetable oils (150.4-1230.9 mg/100 g), followed by legumes (129.6-275.6 mg/100 g), nuts (18.9-255.2 mg/100 g), and cereals (11.9-93.8 mg/100 g). Vegetables and fruits contained lower contents of total phytosterols. Phytosterols were mainly esterified in most common foods except in nuts. The predominant phytosterols were β-sitosterol, campesterol, and stigmasterol, all of which belonged to plant sterols and 4-desmethylsterols. Total phytosterol intake varied across different regions, ranging between 257.7 and 473.7 mg/standard-person (sp)/day, with the highest intake in Beijing, followed by Hangzhou, Wuhan, Chongqing, and Guangzhou. However, phytosterol proportion was similar across regions, with β-sitosterol accounting for 46.5-50.3% of the natural intake. Phytosterol intake was mainly constituted by plant sterols and 4-desmethylsterols in esterified form (61.9-74.6%). At the age of 2-70 years, phytosterol intake ranged from 154.3 mg/day to 348.0 mg/day in the national scale.

    Dietary sources of vitamin D (both natural and fortified) are increasingly contributing to consumers' vitamin D intake and status. Therefore, the present study aimed to validate a vitamin D food frequency questionnaire (FFQ) for the assessment of habitual vitamin D intake. A total of 49 apparently healthy consenting adults (aged 18-64 years) from the local community were sampled at the end of winter. Dietary intakes were recorded using a 4-day weighed food record (4d-WFR) and a 17-item FFQ based on foods known to contribute to dietary vitamin D intake. Fasting vitamin D status was quantified by serum 25-hydroxyvitamin D [25(OH)D] using liquid chromatography tandem mass spectrometry. The method of triads was applied using these three measurements to determine the overall validity of the FFQ. Vitamin D intakes from 4d-WFR ranged between 0.42 and 31.65 μg day(-1), whereas intakes determined from the FFQ ranged from 1.03 to 36.08 μg day(-1). Serum 25(OH)D concentrations ranged between 12.89 and 279.00 nmol L(-1). The mean (SD) difference between the FFQ and 4d-WFR was +1.62 ( 3.86). There were strong correlations between the vitamin D intake estimated by the FFQ and that from the 4d-WFR (r = 0.562) and also with serum 25(OH)D concentrations (r = 0.567). Vitamin D intake estimated from the 4d-WFR was also strongly correlated with serum 25(OH)D concentrations (r = 0.411). The overall validity coefficient calculated using the method of triads was high (0.881). The vitamin D FFQ has been validated for use in future studies aiming to assess habitual vitamin D intake. © 2015 The British Dietetic Association Ltd.

    Poor nutrition in adolescent girls poses critical health risks on future pregnancy and birth outcomes especially in developing countries. Our purpose was to assess nutritional status and dietary intake of rural adolescent girls and determine pulse and food intake patterns associated with poor nutritional status. A cross-sectional community-based study was conducted in a traditional pulse growing region of southern Ethiopia on 188 girls between 15 to 19 years of age, with 70% being from food insecure families. Prevalence of stunting (30.9%) and underweight (13.3%) were associated with low food and nutrient intake. Diets were cereal-based, with both animal source foods and pulses rarely consumed. Improving dietary intakes of female adolescents with nutrient dense foods would ensure better health for themselves and for the next generation.

    Research has shown that imagining food consumption leads to food-specific habituation effects. In the present research, we replicated these effects and further examined whether the depletion of self-regulatory resources would reduce the habituation effects of imagined food consumption. Since self-regulatory resources have been shown to reduce habituation effects during the perception of emotional stimuli, we expected a reduction in habituation effects from imagined food consumption when self-regulatory resources were depleted. In Study 1, we replicated habituation effects as a response to imagining gummy bear consumption with a high (36) and medium number (18) of repetitions in a camouflaged taste test. Participants imagining gummy bear intake showed decreased food intake compared with participants who imagined putting a coin into a laundry machine. The number of repetitions did not significantly moderate the observed habituation effect. In Study 2, we investigated whether self-regulatory depletion would impede habituation effects evoked by the imagination of walnut consumption. Participants in a depleted state did not show a reduction in food intake after imagining walnut intake compared with participants in a non-depleted state. We discuss directions for future research and processes that might underlie the observed moderating effect of self-regulatory resources.

    Food advert exposure has been shown to influence calorie intake and food choice in 9-11 year olds. However, little is known about the effect of food advertisements on feeding behaviour in younger children. Therefore, we conducted a study with 93 children aged 5-7 years, 28 of whom were over weight or obese. The children were exposed to 10 non-food adverts and 10 food adverts in a repeated measures design. Their consumption of sweet and savoury, high and low fat snack foods, and fruit were measured following both sessions. Food advert exposure produced a significant increase in total food intake in young children. The collection of recognition data was incomplete. These data replicate previous findings in that exposure to food adverts increases food intake in all children, but recognition of food adverts is related to body mass index (BMI). Beyond their effects on brand choice, exposure to food advertisements (commercials) promotes over-consumption in younger children.

    To examine characteristics of patients with Avoidant/Restrictive Food Intake Disorder (ARFID) in an effort to identify and describe subtypes of the disorder. A retrospective chart review was completed for patients aged 8-17 years assessed over a 17-year period. Seventy-seven patients were included in the study, the majority of whom were female (n = 56, 73%). The average age of patients was 13.7 years (SD = 2.4 years). Three specific subtypes of ARFID (aligning with example presentations outlined in the DSM-5) were identified: (a) those with weight loss and/or medical compromise as a consequence of apparent lack of interest in eating (n = 30, 39%); (b) restriction arising as a result of sensory sensitivity (n = 14, 18%); and (c) restriction based upon food avoidance and/or fear of aversive consequences of eating (n = 33, 43%). Clinical characteristics of patients varied depending on the assigned subtype. Our findings highlight the need for further research into the relative merit of subtype-assignment in patients with ARFID and whether such practice would aid in the recommended treatment. Further research is required to understand whether these categories are generalizable and applicable to other samples such as young children or adults with ARFID, and how treatment options might differ according to subtype. © 2017 Wiley Periodicals, Inc.

    Drywień, Małgorzata E; Galon, Katarzyna

    Fluid intake in elderly is more important than in younger individuals, because compromised homeostatic mechanisms such as loss of the thirst sensation can result in dehydration. The aim of the present study was the assessment of water intake from food and beverages by free-living elderly in Poland. The study was conducted on 138 volunteers (women and men) at the age of 60 to 90, recruited from Warsaw and Płock Universities of the Third Age and different informal groups from the same cities. Food and beverages consumption data were collected using the method of records for 3 days, including two weekdays and one week-end day, in the period April – June 2012. Average values of total water intake in the present study indicated that women meets of the European Food Safety Agency recommendations (2000 mL/day), but men did not (less about 200 mL/day than the recommended 2500 mL/day). Taking into account the criterion of water per energy intake (mL/kcal) 51% of women and 75% of men did not meet the recommendation. Continuation of the careers and/or participation in Universities of the Third Age contributed to less intake of water from beverages, what in turn affected the total water intake. The elderly leading an active life (working, studying) may be a risk group vulnerable to dehydration, so monitoring is needed.

    Food intake, body weight and weight of some organs were studied in male Wistar rats within 25 days of continuous gamma irradiation at a dose rate of 15.48 x 10/sup -3/ C/kg (6O R) per day in an experimental gamma field. A decrease in food intake and body weight and a decrease in thymus and spleen weights were found during the first week in irradiated rats. The thymus and spleen involutions did not progress within the second week. From the beginning of the third week till the end of the experiment the irradiated animals increased their weight and the food intake was even higher during the last week of irradiation in comparison with controls. The spleen and thymus involutions stopped but the weight remained at the lower level. The relative weight of the adrenal glands in irradiated animals only increased at the end of the period.

    Full Text Available As of 2013, 42 million American households were involved in growing their own food either at home or in a community garden plot. The purpose of this pilot study was to document the extent to which gardeners, particularly less affluent ones, increase their vegetable intake when eating from either home or community garden spaces. Eighty-five community gardeners and 50 home gardeners from San Jose, California, completed a survey providing information on demographic background, self-rated health, vegetable intake and the benefits of gardening. The gardeners surveyed were generally low income and came from a variety of ethnic and educational backgrounds. Participants in this study reported doubling their vegetable intake to a level that met the number of daily servings recommended by the U.S. Dietary Guidelines. Growing food in community and home gardens can contribute to food security by helping provide access to fresh vegetables and increasing consumption of vegetables by gardeners and their families.

    were measured by Fick's Principle. Food intake before exercise reduced whole-body lipid combustion during exercise to about 50% of the combustion rate found during exercise in the fasted state. The increase in subcutaneous, abdominal adipose tissue lipolysis during exercise was not influenced...... by preexercise food intake, while the fatty acid mobilization was increased by only 1.5-fold during postprandial exercise compared to a fourfold increase during exercise in the fasted state. During exercise, catecholamine concentrations increased similarly in the fasted and the postprandial state, while...... for by changes in the regional splanchnic tissue or adipose tissue triacylglycerol metabolism. Exercise was able to increase hepatic glucose production irrespective of food intake before exercise. It is concluded that exercise performed in the fasted state shortly before a meal leads to a more favourable lipid...

    The aim of this study was to evaluate the effect of hemodialysis (HD) duration on food intake and nutritional markers in patients with chronic kidney disease (CKD). Twenty CKD patients received maintenance HD over a 9-year period. At the beginning of the study (T0) and at 3-year intervals (T1, T2, and T3) during the 9-year follow-up, a nutritional survey using the 24-h recall and record method was repeated for 4 days, and the blood samples were drawn. The results from T0 were used as references. Nutritional status was assessed through food intake, nutritional markers (urea, uric acid, creatinine, cholesterol, total protein, and albumin), and anthropometric measurements (height, dry weight, and body mass index). HD duration was correlated with energy intake (r = -0.89, P protein intake (r = -0.50, P intakes were noted in patients at T1 (-8%), T2 (-38%), and T3 (-59%) with decreased fiber intakes. Lipid intake was diminished by 11, 17, and 25% in patients, respectively, at T1, T2, and T3. The consumption of milk and dairy products, meats, fish, eggs, fruits, vegetables, and fat was reduced at T1, T2, and T3. In conclusion, long-term HD fails to correct undernutrition caused by CKD. Long-term dialysis complications could be reduced with preventive measures, including the use of biocompatible membranes and high-dose dialysis. Consequently, patients could experience a decreased prevalence of protein-energy malnutrition.
