Study Of A Contemporary Diet In One Household In The Yucatan, Ericka K. Hardin

Mahurin Honors College Capstone Experience/Thesis Projects

The history of the Yucatan has played a major role in the development of the food system of the area and the nutritional status of the population. Originating from an agricultural based diet, which forms the foundation of the traditional Yucatan diet, there has been a recent shift away from whole and natural foods to a more processed and convenient food supply due to the influx of American products and culture. Coinciding with the influx of these unhealthy foods, there has also been a rise in the health problems of the Mexican population such as heart disease and diabetes, both …

By seeking this understanding, I hope that this project may serve as a tool to …

Food And Identity Formation Among Jain Laywomen, Kristin Mcconnell

Independent Study Project (ISP) Collection

The Jains are a small but influential minority community in India. Their religion is structured around the concept of ahimsa, the strict adherence to nonviolence in one’s every under taking. The ideal Jain diet does the least amount of harm to both oneself and one’s environment, including plants and microscopic organisms. Many foods — including meat, honey, alcohol, and underground vegetables — are forbidden. While Jain philosophy is adamant about avoiding foods that are obtained through violence, it says little about the perspectives and lifestyles of those most often charged with maintaining this diet: Jain laywomen. Because these women are …

Calcium And Leucine Modulation Of Airway Inflammation, Patricia Louise Brown

Doctoral Dissertations

Over the past several decades the prevalence of obesity and asthma have increased in a parallel fashion. Recent studies reported a positive relationship between the two disorders that may in fact be causal. Although the link between obesity and asthma has become widely recognized, the underlying pathophysiological connection is not elucidated. Increased markers of inflammatory and oxidative stress are present in obesity and asthma suggesting the link is immunological. The systemic inflammation observed in obesity may potentially initiate adverse affects in the airways. Previous studies have shown that consumption of dairy foods (rich in calcium and leucine) suppress 1,25-dihydroxycholecalciferol (calcitriol) …

Role Of Vitamin A Status And Its Catabolism In The Regulation Of Glucose And Lipid Homeostasis In Rats Under Physiological And Disease Conditions, Yang Li

Doctoral Dissertations

The increased number of individuals with metabolic diseases has become a public health concern. Vitamin A (VA, retinol) is required to maintain the general health of an individual. How VA contributes to the regulation of glucose and lipid homeostasis in normal and metabolic disease states is unclear. VA’s physiological activities are mainly mediated by its metabolite, retinoic acid (RA), which activates several transcriptional factors in the nuclear receptor super family and in turn, regulates the expression of numerous genes for macronutrient metabolism. For the RA production, retinol is first oxidized into retinal and then from retinal to RA. We hypothesize …

Fresh Bytes - Connected Hydroponics For Small-Scale Growing, Jack Bowen

Liberal Arts and Engineering Studies

Many users are now transitioning to small-scale hydroponics and aquaponics at home. There can be a barrier to entry with these systems as there is a delicate balance of chemicals, pH, etc. that must be maintained. There are sensors for these various components but they are either aimed at commercial production or are un-automated. Fresh Bytes is a microcomputer with sensors to detect all of these unseen components in a hydroponic system. A prototype of this microcomputer is produced along with CAD plans for more professional versions of it. The sensors are verified and future development is contemplated.

A Retrospective Observational Study Of Maximal Enteral Nutrition Rates In A Burn Patient Population, Stephanie Phillips

Theses & Dissertations

Enteral nutrition (EN) is frequently interrupted in the critically ill patient, which can lead to nutritional deficits and severe weight and lean body mass loss. Increased EN rates are being used more frequently to account for these interruptions. This study examined the maximum hourly EN rate (MAX rate) received by each subject and evaluated outcomes and tolerance in an effort to determine if there is a maximum threshold for the EN rate in this population. This retrospective observational study was conducted on an adult population admitted to a major burn center during a three year period who received EN and …

Research trials were conducted to evaluate the effects of different levels of dietary grain sorghum on broiler live performance, carcass yield and shank (leg) and breast skin coloring. Iso-caloric diets were formulated where sorghum replaced corn at rates of 0% (control), 20, 40, 60, 80 and 100% for a total of 6 diets. For each of the two trials, 1500 Cobb 500 male broiler chicks were randomly allocated to 60 pens with 25 birds per pen (10 pens/diet) and grown to 46 days for the first research trial and 41 days for the second. There were no differences (P>.05) …

Evaluation Of Phytate And Phytase Interactions And Phytase Phase-Feeding On Bird Performance, Bone Characteristics And Meat Quality In Young Growing Broilers, Chance L. Williams

Graduate Theses and Dissertations

Two trials were performed using one-day-old male Cobb x Cobb 500 broilers to determine how dietary phytate and phytase levels as well as phytase phase feeding impacted bird performance parameters, tibia characteristics, and malonaldehyde (MDA) content of the liver, breast and thigh tissues. The first experiment consisted of 1,008 birds randomly placed in 48 floor pens within two commercial broiler houses at the Applied Broiler Research Farm (ABRF; 21 birds per pen; 0.76 ft2 per bird). A 2 X 3 factorial design was used with two levels of dietary phytate (0.21 and 0.31 %) and three levels of phytase supplementation …

Dietary Behaviors And Nutrition Intervention Preferences Of Breast Cancer Survivors, Sherry A. Stokes

All Theses

Breast cancer is the most commonly diagnosed cancer among women and there are expected to be 1,665,540 new cases diagnosed in 2014. Advancements in early detection, have greatly improved treatment outcomes for the majority of these patients and the 5-year survival rate is 89.2%. The newly emerging field of survivorship care is an attempt to meet the unique needs of this expanding population. Research has demonstrated that an unhealthy body weight is an important modifiable risk factor for the recurrence of breast cancer. This study used an electronic version of the Block 2005 to collect dietary information on 30 breast …

Effects Of Grain Sorghum Muffin On Blood Glucose And Insulin Responses In Prediabetic Men, Xuan Gu

Graduate Theses and Dissertations

Prediabetes is a sub-health condition in the development to type 2 diabetes, which has been long overlooked. Grain sorghum contains functional starch fractions, which have been widely reported for their potential on blood glucose control and diabetes prevention. A human study with prediabetic men was conducted to investigate the effects of sorghum starch on postprandial blood glucose and insulin levels. Grain sorghum and wheat (control) muffins containing 50 g total starch were consumed by 15 prediabetic male subjects on two mornings with a 1-week washout period. Plasma samples were collected on -15 (baseline), 0, 15, 30, 45, 60, 75, 90, …

Evaluation Of Betaine And Methionine Replacement For Improving Performance And Meat Quality For Broilers Reared Under Higher Temperature Conditions, Malea Graham Frank

Effects Of A Nutrition Education Intervention On Inner City Children, Stephanie P. Windle

Honors Theses

This paper focuses on nutrition education research conducted between February and April 2014. The researcher’s goal was to determine the effectiveness of a nutrition education intervention on low-income children. The USDA and Academy of Nutrition and Dietetics provided most of the research used to create the intervention. The definition of “healthy” used for this study was defined by the USDA (2014) as “whole foods such as fruits, vegetables, whole grains, fat free or low-fat dairy, and lean meats that are perishable (fresh, refrigerated, or frozen) or canned as well as nutrient-dense foods and beverages encouraged by the 2010 Dietary Guidelines …

Understanding Lipid Oxidation In Low-Moisture Food, Leann M. Barden

Doctoral Dissertations

Low-moisture snacks account for much of the saturated fat in the diet, making them a key target for improving consumers’ health. However, it is not currently feasible to maintain the same shelf life when replacing saturated fats with unsaturated fats in these products. The first study characterized the microstructure of a low-moisture cracker model system and determined the impact of iron, chelators, and free fatty acids (FFA) on lipid oxidation kinetics. Confocal microscopy showed that lipids form a continuous layer surrounding the small and/or minimally gelatinized starch granules. Lipid-starch, lipid-air, and starch-lipid-protein interfaces all existed. Oxidation studies showed a large …

Intuitive Eating, Attitudes To Food, And Body Size: A Comparison Between Nutrition Majors And Non-Majors, Katelyn Russell

Masters Theses

Dietitians are expected to deliver sound and scientifically objective advice to the general public, yet their personal beliefs and behaviors could influence delivery of nutrition care. Increased understanding of the personal attitudes and behaviors of dietitians concerning eating behavior and body image could help improve dietetic practice. Traditional nutrition education emphasizes cognitive eating, i.e., monitoring energy intake and comparing macronutrient intakes to the current acceptable ranges. Intuitive eating, however, promotes the release of cognitive eating in favor of greater attention to physiologic cues, or “body wisdom”. We hypothesized that nutrition students in a traditional curriculum would report eating less intuitively …

The Role Of Sleep Timing On Diet Quality And Physical Activity Among College-Aged Women Participating In The University Of Massachusetts Vitamin D Status Study, Deniz Azarmanesh

Masters Theses

Overweight and obesity are risk factors for various chronic diseases. Sleep has been associated with overweight and obesity. One potential mechanism by which sleep may lead to overweight and obesity is through positive energy balance (i.e. energy intake exceeding expenditure). There are few studies examining the impact of sleep timing (onset and wake time) on diet and exercise. In a cross sectional study, we examined associations between sleep timing and diet quality, and in separate models, between sleep timing and meeting the 2008 Physical Activity Guidelines for Americans among the participants of the UMass Vitamin D Status Study. A total …

Veggiecation: A Novel Approach To Improve Vegetable Consumption Among School-Aged Children, Yeon Bai, Lisa Suriano, Shahla M. Wunderlich

Department of Nutrition and Food Studies Scholarship and Creative Works

Children's general preference for sweeter foods and aversion to bitter vegetables is explained partly by fear of new food and social and cultural influences. Reluctance to eat new foods is related to unfavorable facial expressions and is often learned from the child's family, social circle, and culture.1 Researchers report that the fruit and vegetable consumption of children 6–12 years of age is associated with the accessibility and availability.2 School-based interventions that combine classroom curricula, parental, and nutrition service components show the greatest promise for fruit and vegetable promotion among children.

The Fat Of The Matter: How Dietary Fatty Acids Can Affect Exercise Performance, Barbara J. Pierce, Scott R. Mcwilliams

Biology Faculty Publications

Fatty-acid composition of fat stores affects exercise performance in a variety of vertebrates although few such studies focus on flying vertebrates such as migratory birds, which are exceptional exercisers. We first discuss the natural variation in quality of fat available in natural foods eaten by migratory birds and their behavioral preferences for specific fatty acids in these foods. We then outline three proposed hypotheses for how dietary fatty acids can affect exercise performance, and some of the evidence to date that pertains to these hypotheses with special emphasis on the exercise performance of migratory birds. In theory, selectively feeding on …

Relationship Of Dna Methylation With Cardiovascular Fitness And Body Composition, Mihaela A. Ciulei

Honors College Theses

Global DNA Methylation (GDM), an epigenomic modification has been linked to the development of cardiovascular disease and its risk factors. Our focus was to identify potential relationships between epigenetic alterations and both cardiovascular fitness and body composition measures. Purpose: As increases in aerobic fitness have a beneficial effect on cardiovascular disease, one purpose was to determine if a relationship was evident between global DNA methylation and VO2max. A secondary purpose was to determine if the relationship extends to body composition measured via Dual X-ray Absorbtometry (DXA). Methods: Fifty-two (male n=25, female n=27) subjects provided a blood sample for DNA …

Souza, Andreo F. Aguiar, Ivan Jose Vechetti Jr, Dijon H.S. Campos, Ana A. H. Fernandes, Katashi Okoshi, Robson F. Carvalho, Antonio C. Cicogna, Maeli Dal-Pai-Silva

Department of Nutrition and Health Sciences: Faculty Publications

Background: Heart failure (HF) is associated with cachexia and consequent exercise intolerance. Given the beneficial effects of aerobic exercise training (ET) in HF, the aim of this study was to determine if the ET performed during the transition from cardiac dysfunction to HF would alter the expression of anabolic and catabolic factors, thus preventing skeletal muscle wasting. Methods and Results: We employed ascending aortic stenosis (AS) inducing HF in Wistar male rats. Controls were sham operated animals. At 18 weeks after surgery, rats with cardiac dysfunction were randomized to 10 weeks of aerobic ET (AS-ET) or to an untrained group …

The Role Of Adiponectin And The Adipocyte In Energy Metabolism And Inflammation, Sheila Kay Jacobi

Open Access Dissertations

A series of experiments were conducted to characterize the autocrine role of adiponectin in modulating fatty acid metabolism and inflammation in the pig. In the first study, we cloned and sequenced the porcine adiponectin open reading frame and evaluated the regulation of adiponectin, in vitro and in vivo. The porcine sequence shares approximately 88, 86, 85 and 83% homology with the dog, human, cow and mouse adiponectin, respectively, and 79–83% similarity with dog, human, cow and mouse proteins at the amino acid level, based on the translated porcine sequence and GenBank submissions for the other species. Analysis of serum from …

The Impact Of An Omega-3 Enriched Diet On Hyperactivity And Biochemistry In An Animal Model For Attention-Deficit/Hyperactivity Disorder, Nadine M. Hammoud

Open Access Theses

Attention-deficit/hyperactivity disorder (ADHD) is the most diagnosed behavioral disorder in children. It affects around 5% of children worldwide and 11% of children in the United States, with rates increasing. Pharmaceutical treatments, such as amphetamines and methylphenidates, are not effective for everyone and are known to have unwanted side effects. While the etiology of the disorder is not yet fully understood, there are clear genetic and environmental components. Nutritional insufficiencies have recently become a popular environmental risk factor under investigation. Essential fatty acids (EFA), omega-3 polyunsaturated fatty acids (PUFA) in particular, are needed for proper brain development and function. Our lab …

Analysis Of Vitamin E Metabolites By Liquid Chromatography-Tandem Mass Spectrometry, Tianlin Xu

Open Access Theses

Naturally occurring forms of Vitamin E are metabolized to various carboxychromanols and conjugated carboxychromanols. Recent studies showed that vitamin E metabolites, especially the long-chain carboxychromanols are more bioactive than unmetabolized vitamin E forms. It is necessary to quantify vitamin E metabolites in biological environment. Here a simple and effective extraction method was developed to achieve extraction efficacy of more than 90% of various forms of vitamin E and metabolites with less than 10% inter- or intra-day variation. An LC-MS/MS assay was developed and optimized to acquire best sensitivity for the detection of vitamin E and metabolites. This method allows simultaneous …

Adipogenic And Myogenic Stem Cells In Brown Fat: A Study Of Progenitors And Regenerative Capacity, Xin Yang

Open Access Theses

Brown adipose tissue (BAT) utilizes stored lipids to generate heat, therefore reducing body fat content and favoring a leaner body composition. Recent identification of metabolically active BAT in adult humans has sparked broad interests in understanding the developmental origin and postnatal homeostasis of BAT. However, the stem cell population that gives rise to BAT during development and maintains BAT mass at postnatal stage has not been characterized. In addition, whether adult BAT has the capacity to regenerate after injury or to proliferate in response to cold is flargely unknown. Furthermore, although BAT and skeletal muscle are known to share a …
