AbstractObjective:To demonstrate that dietary datasets from the Continuing Survey of Food Intakes by Individuals, a US population survey, allow comparisons with national data and provide food composition datasets that can be used to generate similar dietary data.Design:Two studies are described: the Lower Mississippi Delta Nutrition Intervention Research Initiative (Delta NIRI), which used a 24-hour recall, and a Department of Defense Military Nutrition Research Task, which used 3-day dietary records. Both studies used the same food composition tables.Setting:Rural Lower Mississippi Delta and an Army post.Subjects:Four hundred and nine residents (adults and children) from the rural Delta region of Arkansas, Louisiana and Mississippi, and 74 career soldiers from the Sergeants Major Academy, Fort Bliss, Texas.Results:The Delta NIRI study found that fruit and vegetable consumption for these rural residents was lower than that found nationally. Additionally, the quality of vegetable servings is of concern since a large percentage came from french fries and potato chips. In the Sergeants Major Academy study, the national survey food composition tables allowed for easy analysis of intake data and comparisons with dietary recommendations.Conclusions:Strategies similar to those used for the Delta NIRI and Military Nutrition Research Task can be used widely, allowing comparisons of ‘defined populations’ with nationally distributed data. Additionally, measurement of dietary change is more efficient when the same protocol is used subsequently to collect more data, a method similar to that used by the US Department of Agriculture to describe food consumption patterns from one survey to another.

AbstractStarting university is an important time with respect to dietary changes. This study reports a novel approach to assessing student diet by utilising student-level food transaction data to explore dietary patterns. First-year students living in catered accommodation at the University of Leeds (UK) received pre-credited food cards for use in university catering facilities. Food card transaction data were obtained for semester 1, 2016 and linked with student age and sex. k-Means cluster analysis was applied to the transaction data to identify clusters of food purchasing behaviours. Differences in demographic and behavioural characteristics across clusters were examined using χ2 tests. The semester was divided into three time periods to explore longitudinal changes in purchasing patterns. Seven dietary clusters were identified: ‘Vegetarian’, ‘Omnivores’, ‘Dieters’, ‘Dish of the Day’, ‘Grab-and-Go’, ‘Carb Lovers’ and ‘Snackers’. There were statistically significant differences in sex (P < 0·001), with women dominating the Vegetarian and Dieters, age (P = 0·003), with over 20s representing a high proportion of the Omnivores and time of day of transactions (P < 0·001), with Dieters and Snackers purchasing least at breakfast. Many students (n 474, 60·4 %) changed dietary cluster across the semester. This study demonstrates that transactional data present a feasible method for dietary assessment, collecting detailed dietary information over time and at scale, while eliminating participant burden and possible bias from self-selection, observation and attrition. It revealed that student diets are complex and that simplistic measures of diet, focusing on narrow food groups in isolation, are unlikely to adequately capture dietary behaviours.

Summary. Aging is a complex set of events that involves the whole body. However, disruption of the central nervous system (CNS) function is the aspect of aging that elderly people worry about most. Aging has different effects on different aspects of neurological function. Our knowledge of the basic molecular mechanism of brain aging has significantly improved over the past few decades. The rate of aging is not fixed, but is plastic and subject to modifications. The environmental factor proven to be very potent in modulating aging is reduced dietary intake. Dietary restriction (DR) is a vigorous nongenetic and nonpharmacological intervention that is known to delay ageing and increase an active and healthy lifespan in diverse species, from yeast to mammals. Additionally, DR can improve various brain functions, including learning and memory, synaptic plasticity and neurogenesis.

A strong link has been made between dietary content and cardiac disease risk. Diets high in fruits, vegetables, whole grains, fish and poultry and lower in red meat have been shown to lower cardiac disease risk in both women and men. National diet guidelines, such as the Canada’s Food Guide (CFG), provide information on basic healthful eating. The CFG, however, lacks the details that are recommended in several cardiac disease-specific diets. The Alternate Health Eating Index (AHEI) is a scoring index that accounts for specific dietary factors such as types of fat, forms of carbohydrates and specific protein sources. High levels of adherence to the AHEI are associated with significantly lower cardiovascular disease risk in both men and women. This study evaluated dietary pattern for cardiac participants over a 16 month period; AHEI score and CFG adherence were measured, AHEI trends over time were examined and differences in AHEI scores based on sex, education level and income were examined. There was moderate correlation between the AHEI and CFG scores (r= 0.73, p=0.001). There were no significant changes over time for either food score and no sex differences noted. Participants with an education level greater than high school had significantly higher AHEI scores at baseline. Intake of fruits and vegetables did not meet recommended amounts at any time, though fibre intake well exceeded the recommendations for both men and women. Future evaluation of patients who receive formal cardiac rehabilitation may improve understanding of how the AHEI can be used as a tool for dietary evaluation in cardiac patients.

Thesis advisor: Thanh V. Tran Research has established that dietary quality among Asian immigrants declined after immigrating to the United States, indicated by decreasing intake of healthy food and increasing intake of unhealthy food. There is a need for a broader investigation for the interactive influence of acculturation, sociodemographic and environmental factors on dietary intake among this population. Guided by the Operant Theory of Acculturation, and the Dietary Acculturation Theory, the present study examined the following research questions to address the gaps in the literature: (1) Are acculturation factors associated with dietary intake among Asian immigrants? (2) What sociodemographic factors are associated with dietary intake among Asian immigrants? (3) What environmental factors are associated with dietary intake among Asian immigrants? (4) What sociodemographic factors moderate the effect of acculturation on dietary intake among Asian immigrants? (5) What environmental factors moderate the effect of acculturation on dietary intake among Asian immigrants? The data in use come from the 2011 – 2012 Adult California Health Interview survey. The sample includes 2,122 non-Hispanic Asian adults born out of the United States. Results from negative binomial regression indicate that intake of fruits, vegetables, soda, fries and fast food was all negatively associated with living in the United States for at least 10 years, compared to living in the Unites States for less than 10 years. The present study also found sociodemographic (including ethnicity, age, gender, education, employment status, and income) and environmental factors (including family type, household size, household tenure, housing type, perceived availability of fresh fruits and vegetables, residential area category, and participation in food stamp and WIC) statistically significantly confounded and moderated the association between length of time lived in the United States and dietary intake. Findings from this study extend the understanding of the protective and risk factors for Asian immigrants to develop and maintain healthy diet, and demonstrated the complexity of dietary changes among Asian immigrants. Based on the findings, the importance that social work research and practice in addressing nutrition inequality among Asian immigrants was highlighted. The study also discovered potential issues and challenges of developing measurement for dietary intake among Asian immigrants, and provided empirical evidence of longitudinal research designs to further explain dietary changes, and guidelines for community-based interventions to address strategies of nutrition promotion among Asian immigrants Thesis (PhD) — Boston College, 2017 Submitted to: Boston College.

Master of Science Department of Food, Nutrition, Dietetics and Health Sara K. Rosenkranz Evidence from physical activity interventions suggests that women, in particular, may overcompensate for exercise energy expenditure by increasing caloric intake. Sedentary behavior and poor diet quality are independent risk factors for many major chronic diseases including cardiovascular disease (CVD). It is unknown whether insufficiently active women alter dietary quality or caloric intake when participating in an intervention to reduce sedentary behavior. Insufficiently active women (n=49) working full-time sedentary jobs were randomized into one of two 8-week sedentary interventions occurring during the work week [short breaks (SB) (1-2 min every half hour, n=24) or long breaks (LB) (15 min twice daily, n=25)]. Dietary information was collected through 3-day food records at baseline, week 4 and week 8. Dietary quality was assessed using the Alternative Healthy Eating Index 2010 (AHEI-2010). CVD risk factors (systolic and diastolic blood pressure (BP), fasting cholesterol, triglycerides, and blood glucose, and body mass index) were assessed at baseline and week 8. For all participants there were no changes in AHEI-2010 scores over time (baseline: M=53.4, 95% CI [49.2, 57.6], week 4: M=50.3, 95% CI [45.9, 54.7], week 8: M=48.4, 95% CI [44.1, 52.7], p>0.05). Average caloric intake in the SB group (baseline: M=1943.8 kcals/day, 95% CI [1716.2, 2171.5], week 4: M=1728.8 kcals/day, 95% CI [1462.4, 1995.2], week 8: M=1616.8 kcals/day, 95% CI [1450.2, 1783.4]) decreased significantly from baseline to week 4 (p=0.015) and baseline to week 8 (p=0.002). There were no significant changes in caloric intake in the LB group (p>0.05) at either time point. In all participants, absolute changes in LDL were positively correlated with absolute changes in caloric intake (r=0.473, p=0.005). There were no other significant associations between changes in dietary quality or caloric intake with changes in any other CVD risk factor (p>0.05). Following an 8-week sedentary intervention in the workplace, insufficiently active women did not alter their dietary quality, but decreased caloric intake. Future research should explore sedentary interventions compared to physical activity interventions in women as a means to create negative energy balance, as sedentary breaks throughout the day may be effective for improving health outcomes.

It is unknown if participation in the Supplemental Nutrition Assistance Program (SNAP) influences the magnitude of improvement in dietary intake in response to dietary interventions. Adults with low socioeconomic status (SES) tend to have lower overall dietary quality as compared to those with higher SES. However, low SES adults are more likely to receive benefits from SNAP, which gives nutrition assistance to millions of eligible Americans. The objective of this investigation is to examine differences in dietary intake between 1) SNAP participants, 2) those eligible for SNAP but not receiving (nonparticipants), and 3) those ineligible for SNAP, in response to an intervention targeting a reduction in sugar-sweetened beverage (SSB) consumption. Adult participants (n=146) from Southwest Virginia were enrolled in a 6-month, community-based trial, SIPsmartER. Participants provided SNAP enrollment status and 3 24-hour dietary recalls at baseline and 6-months. Dietary variables (SSB, macronutrients, etc.) and dietary quality data (Healthy Eating Index [HEI-2010]) were derived from nutritional analysis software (NDS-R 2011). Statistical analyses included descriptives and repeated-measures ANOVA. Although SNAP participation and eligibility status did not impact the overall effectiveness of this dietary intervention, the within group data suggests that those eligible for SNAP but not participating (n=30) may be at a disadvantage to improving their dietary intake as compared to those at a similar household income who receive SNAP benefits (n=56) or ineligible individuals at a higher income level (n=60). Future research is needed to explore if participant's ability to maintain long-term adherence to the dietary changes differs between groups. Master of Science

AbstractFood system transformation and dietary changes appear ubiquitous in urban areas of Africa. These changes can be as dramatic and rapid as urbanization processes unfolding on the continent. Large cities, secondary cities and small towns all tend to experience these food system changes at varying degree and in unique ways. There is evidence in the Ghanaian context to suggest that urban food system transformations are more prevalent in smaller than larger cities. This chapter is based on a qualitative investigation into urban residents’ lived experiences regarding dietary changes underpinned by complex processes of urban food system transformation in Tamale. It is inspired by a participant’s remark that “we eat everyday but I’m perpetually hungry,” a sentimental expression that captures people’s frustration about ongoing dietary changes borne out of unsatisfactory food availability that affects their subjective wellbeing. The study reveals that the subjective experience of food security among the elderly men is impacted negatively by the unfolding food system transformation in the city. In addition to agricultural and economic development policies, the increased role of women in food decision making and their increased participation in activities outside of the home fuels the micro-level dietary changes. A recommendation is made to broaden the scope of Ghana’s Livelihood Empowerment Against Programme (LEAP) for purposive targeting and better coverage of the elderly urban poor.

The social significance of donkey milk for human health stems from its potential advantages for vulnerable populations, including children and those with special dietary needs. The variation in its composition throughout lactation indicates that it can be adapted to fulfil the specific nutritional demands of these groups. The focus of this paper is to investigate the chemical profile of donkey milk and the changes that occur during lactation. The study was performed on samples taken at various stages of lactation, from colostrum to milk. The results revealed fluctuations in protein, fat, lactose and dry matter, reflecting the milk's adaptation to the changing needs of the foals. The results indicate a significant increase in lactose content from 6.24% in the second month of lactation to 6.42% in the sixth month. Regarding the protein level, it decreased from 1.88% in early lactation to 1.41% during late lactation. This study has important implications for the use of donkey milk in human nutrition, providing insight into its potential use in product development for targeted sensitive groups such as infants and people with special nutritional needs.

Our study explored the impact of adding avocado to chicken liver pate, focusing on both nutritional composition, oxidative stability and organoleptic (sensory) characteristics. By incorporating avocado, we aimed to create a healthier, more nutritious alternative to traditional pate. Nutritional analysis included determining protein, fat, minerals, water, salt, carbohydrate content, and energy value. The results showed that adding avocado led to a decrease in fat content and an increase in beneficial omega-3 fatty acids and dietary fiber. Peroxide value (PV), TBA value and total oxidation (TOTOX) were determined to assess oxidative stability. These changes significantly improved the pate�s nutritional profile, making it a healthier choice. We also evaluated organoleptic properties, assessing the pate�s taste, smell, texture, and color. Sensory analysis was conducted with a panel of participants who rated the avocado pate on these attributes. The feedback indicated that the avocado-enhanced pate was well-received, with positive ratings for its appearance, flavor, and smooth consistency. The fresh taste of avocado complemented the richness of the chicken liver, while the bright green color added visual appeal. In conclusion, the addition of avocado to chicken liver pate not only improved its nutritional content but also maintained or enhanced its sensory qualities. This suggests that avocado pate is a flavorful and healthy alternative, appealing to consumers looking for both nutrition and taste.

CYP2B6 is a drug metabolizing cytochrome P450 (CYP) that has anti-obesity properties, but also increases non-alcoholic fatty liver disease (NAFLD) in hCYP2B6-transgenic mice compared to Cyp2b-null mice. hCYP2B6-transgenic mice are also more susceptible to perfluorooctane sulfonic acid (PFOS) toxicity, a lipid-like toxicant used in stains, varnishes and firefighting foams that increase NAFLD. Our recent research demonstrates that CYP2B6 metabolizes dietary polyunsaturated fatty acids into the oxylipins, 9-HODE and 9-HOTre, which are strong peroxisome proliferator activated receptor alpha (PPARa) agonists and weak PPARg agonists. The purpose of our studies is to better understand the mechanisms behind PFOS and oxylipin-mediated hepatic steatosis. To test whether PFOS, 9-HODE or 9-HOTrE alter mitochondrial metabolism, Seahorse Mitostress assays were performed using HepG2 cells treated with 0.2, 1 and 5mM PFOS, 9-HODE and 9-HOTrE for 24 hours (n=5). Both PFOS and 9-HOTrE increased spare respiratory capacity in a concentration-dependent manner with lesser effects by 9-HODE. qPCR was performed following exposure of HepG2 cells to 1 and 5 mM of each compound to investigate changes in gene expression that may explain alterations in mitochondrial respiration or hepatic steatosis. PFOS repressed expression of ANGPTL4, a biomarker of PPARgactivation. 9-HODE induced CD36 and FASN expression, genes involved in fatty acid uptake and synthesis. 9-HOTrE induced SREBF1 and Cpt1a expression, genes involved in sterol synthesis and fatty acid transport into the mitochondria and may partially explain the increase in SRC. Thus, based on current results, PFOS is associated with reduced transport of lipids from the liver and 9-HODE increases lipid uptake; both would increase steatosis through different mechanisms. 9-HOTre may increase metabolism and therefore reduce steatosis.

The purpose of this study was to evaluate the dietary habits (DH) and eating behaviors (EB) among adults during COVID-19-induced confinement. For this purpose, an online survey designed to assess the change in DH and EB during April and May of 2020 was distributed using various social media platforms. A total of 1844 participants aged 18-72 years completed the survey. The results outlined an increase (42.5-61.8%) in most of the DH and EB examined in the current study in the majority of the participants. Among these changes, increased (p<0.05) prevalence of fruit and vegetable, immune boosters, water, and hot beverage consumption as well as decreased (p<0.05) eating in restaurants and fatty food consumption, suggest a positive change. Conversely, a greater (p<0.05) percentage of the participants reported an increase in high-calorie food consumption and late night eating indicating a risky behavior for obesity and subsequent chronic complications. Additionally, age, gender, obesity, education, income, and job type seem to contribute (p<0.05) to the changes in DH and EB. Overall, COVID-19-induced confinement seems to compel adults to adopt a specific DH and EB. Though most of these changes were positive, some were negative. The study provides crucial information to design subpopulation recommendations and developmental programs for adults under such conditions.

Nepalese agriculture is facing a number of challenges, including a shrinking cropped area, principally due to land use changes, low competitiveness, and increasing impacts of climate change, leading to a volatile food security situation. Likewise, changing dietary patterns – characterised by less diverse foods and more consumption of energy-dense ultraprocessed and packaged foods – has been the leading cause of malnutrition, especially among children and adolescents. Promoting a millet-based food system has the potential to improve food security and nutrition in the country. However, there has been a declining trend in the production and consumption of millets owing to a number of reasons.

Communities across the world have consumed foods from millet “ as a traditional food and source of nutrition “ for generations. However, with changes in lifestyle and dietary habits, millet has lost its prominence, making many countries dependent on import-driven cereals like rice, wheat, and maize. Despite the potential to address food and nutritional security, millet production has declined. Millet is a climate-resilient crop that have been identified as an alternative to potential cereals in the hilly regions of the Hindu Kush Himalayan region in addressing food and nutrition security, especially under the current climate change scenarios. The UN Food and Agriculture Organization (FAO) has designated the year 2023 as the International Year of Millets.

This position paper explores the importance of promoting investment in alternative agricultural products in Kenya to enhance food security and foster a resilient food system. The paper analyzes the current state of maize production and consumption in Kenya, compares it to neighboring countries, and delves into the challenges and inefficiencies of maize cultivation and transforming household diets. By examining comparable crops within Kenya and East Africa, it highlights potential solutions to the issues plaguing maize production and consumption. The dietary diversity of Kenyan households and its changes over time are investigated to identify underlying causes, and the unchanging demand for calorie-dense foods like maize is scrutinized. The paper proposes a paradigm shift towards a diversified food system and assesses past structural and behavioral interventions, identifying gaps that require attention.

There is a direct correlation between successful metamorphosis from larvae to post-larvae and the quality of the resultant juveniles or fry. Juvenile quality, in turn, is a major factor influencing fish production level and market price. However, following the profound morphological and physiological changes occurring during metamorphosis, the emerging juveniles in some species characteristically demonstrate heterotrophic growth, poor pigmentation, cannibalism and generally poor survival. The white grouper (Epinephelus aeneus) in Israel and the Pacific threadfin (Polydactylussexfilis) in Hawaii are two promising candidates for mariculture that have high market value but a natural fishery that has sharply declined in recent years. Unfortunately, their potential for culture is severely hampered by variable metamorphic success limiting their production. The main objective was to compare the efficacy and economic viability of dietary or environmental iodine on metamorphic success and juvenile quality in the white grouper and the pink snapper which would lead to improved commercial rearing protocols and increased production of these species both in Israel and the US. The Hawaii Institute of Marine Biology encountered problems with the availability of pink snapper brood stock and larvae and changed to Pacific threadfin or moi which is rapidly becoming a premier aquaculture species in Hawaii and throughout the Indo-Pacific. The white grouper brood stock at the National Center for Mariculture was lost as a result of a viral outbreak following the sudden breakdown of the ozone purification system. In addition, the NCM suffered a devastating fire in the fall of 2007 that completely destroyed the hatchery and laboratory facilities although the BARD project samples were saved. Nevertheless, by studying alternate species a number of valuable findings and conclusions that can contribute to improved metamorphosis in commercially valuable marine species resulted from this collaborative effort. The Israeli group found that exposing white grouper larvae to external TH levels synchronized and increased the rate of metamorphosis. This suggested that sub-optimal synthesis of TH may be a major factor causing size heterogeneity in the larval population and high mortality through cannibalism by their larger more metamorphosed cohorts. Two protocols were developed to enrich the larvae with higher levels of the TH precursor, iodine; feeding iodine enriched Artemia or increasing the level of seawater iodine the larvae are exposed to. Results of accumulated iodine in gilthead seabream larvae indicated that the absorption of iodine from the water is markedly more efficient than feeding iodine enriched Artemia nauplii. Samples for TH, which will be analyzed shortly, will be able to determine if another dietary factor is lacking to effectively utilize surplus tissue iodine for TH synthesis. Moreover, these samples will also clarify which approach to enriching larvae with iodine, through the live food or exposure to iodine enriched seawater is the most efficient and cost effective. The American group found that moi larvae reared in ocean water, which possessed substantially higher iodine levels than those found in seawater well water, grew significantly larger, and showed increased survival compared with well water reared larvae. Larvae reared in ocean water also progressed more rapidly through developmental stages than those in low-iodine well seawater. In collaboration with Israeli counterparts, a highly specific and precise radioimmunoassay procedure for thyroid hormones and cortisol was developed. Taken altogether, the combined Hawaiian and Israeli collaborative research suggests that for teleost species of commercial value, adequate levels of environmental iodine are more determinate in metamorphosis than iodine levels in the live zooplankton food provided to the larvae. Insuring sufficiently high enough iodine in the ambient seawater offers a much more economical solution to improved metamorphosis than enriching the live food with costly liposomes incorporating iodine rich oils.

The BIeNGS programme was ultimately designed to lead to improved nutrition status of children and mothers in the two Bangladeshi districts of Jamalpur and Sherpur. This report summarises the endline findings from the evaluation of the BIeNGS programme. This comprised of a mixed methods design combining quantitative surveys with project beneficiary households, Community Clinic and CNP staff together with a qualitative and process component to gather community and implementer perspectives and process monitoring data. Quantitative findings provide a ‘before-after’ comparison of project logframe indicators amongst core target groups (i.e. women and children) in line with the project’s theory of change. Qualitative findings provide complementary, in-depth perspectives on the effectiveness and sustainability of BIeNGS activities from the perspective of beneficiaries engaged in various project components (including Producer Groups, MenCare Groups, CG, CVA and Adolescent Clubs), as well as implementing partners’ experiences. Comparing baseline and endline results, we see many positive changes in these indicators, particularly in terms of an improvement in overall food security and the frequency of consumption of different food groups in the past seven days, children’s dietary diversity, particularly amongst girls, children’s diet frequency and overall adequacy; consumption of iron-rich and zinc-rich foods, mothers dietary diversity and consumption of healthy and nutritious foods (including green leafy vegetables and eggs); and consumption of Iron and Folic Acid (IFA) during pregnancy. Accompanying these nutritional improvements, we also see positive improvements in nutrition knowledge from baseline to endline, nutrition knowledge for adolescent girls, the proportion of children who are fully immunized and 100% coverage of treatment of child diarrhoea with oral rehydration salts. We also see that many indicators improved most amongst the poorest households compared to the rest of the population, including in stunting, MAD and exclusive breastfeeding. Several aspects of the programme were targeted at women and gender relations, particularly producer groups, but also the Infant and Young Child Feeding (IYCF) support delivered by both community health clinics (the target of the programme’s capacity strengthening) and the programme’s own dedicated community nutrition promotors. Such activities also included the MenCare component, which was designed to tackle men’s role in family care structures and to address wider patriarchal structures. Here we see some similarly impressive results: improvements in women’s participation in agricultural activities; women’s feeling that they have inputs in health and nutrition matters and women’s feelings that they have control over their income. Some of these increases are particularly strong, where, for example, in Jamalpur, women’s involvement in grain farming went from 32% to 60%, high value crop farming from 6% to 25%.

The long term goal of the proposed research, "Influence of small intestinal protein on carbohydrate assimilation and metabolism in beef and dairy cattle" was to define the limits of small intestinal starch digestion and clarify regulatory mechanisms involved in starch assimilation in cattle. It was hypothesized that dietary protein plays a critical role in the regulation of intestinal digestion; however, studies clearly identifying this role were lacking. The first two experiments quantified starch digestion (disappearance from the small intestine) in response to known increments in duodenal protein supply and found that the quantity of DM, OM and starch disappearing from the small intestine increased linearly (P <.01) with protein infusion. A follow-up experiment also demonstrated that casein infusion linearly increased pancreatic a-amylase concentration and secretion rate. The final experiment provided critical data on metabolic fates of glucose derived from intestinal starch digestion. These data demonstrated that increasing postruminal starch supply does increase the metabolism of glucose by visceral tissues: however, this increase is minor (20%) compared with the increase in portal production (70%). These changes can have a dramatic impact on the glucose economy of the animal and result in large increases in the amount of glucose reaching peripheral tissues.
