Characterizing The Fitness Landscapes Of Gut Symbionts In Defined Community And Diet Contexts, Meng Wu

Arts & Sciences Graduate Student Theses and Dissertations

A species' niche is the description of all the environmental conditions required to permit a population of that species to persist, including the effects of the population on those conditions. This definition includes the species' resource requirements, as well as stress tolerances and interactions with other species acting as competitors, predators, parasites, and mutualists. The human gut microbiota serves as a microbial `metabolic organ' tasked in part with the biotransformation of many components of our diet. Relatively little is known about the factors that allow members of the human gut microbiota to persist in a habitat that experiences marked changes …

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 …

Effects Of Selected Commercial Diets And Yeast Substitution On The Growth And Associated Microbiota Of Rotifer (Brachionus Plicatilis), Ryan D. Lind

Open Access Theses

The rotifer (Brachionus plicatilis) is an essential feed organism for successful marine larviculture. Cost effective feeding regimes and the control of harmful bacteria are critical components of rotifer production. Supplementation of commercial diets with yeast can reduce costs, but its effects on bacteria such as Vibrio spp. are not well documented. Two experiments were conducted to identify a practical culture diet. The first experiment evaluates different commercial diets on rotifer growth and total Vibrio. The second experiment determines a practical level of yeast substitution, with regard to rotifer growth, culture Vibrio loads, and cost. The diets evaluated in the first …

The Food Access in Michigan Project is studying the relationship between food insecurity and food environments in Michigan.

Objectives The purpose of this study was to determine the characteristics of the diet of homeless women in Heartside. This study examined the level of food …

"You Are What You Eat": How Diet Can Influence The Gut Microbiota Of Marine Invertebrates, Malin Tietjen

The Plymouth Student Scientist

Microorganisms are omnipresent in every ecosystem on earth and the majority of identified species belong to the domains Bacteria and Archaea of which bacteria are considered to represent the greatest diversity (Staley et al., 2007). Microbes are organised in complex and diverse communities depending on the environmental conditions, and they commonly live closely associated with eukaryotic hosts. The body surfaces of nearly all higher organisms are populated by diverse microbial communities and this microbiota is understood to have large impacts on the hosts’ biology (Ley et al., 2008). The greater part of the microbiota consists of microorganisms that are beneficial …

The Effects Of Probiotics Supplementation On Health Using Caenorhabditis Elegans As A Model System, Miranda Klees

All Theses

The 'Western Diet,' prominent among developed nations, often refers to a diet rich in meat proteins and refined sugars. Western society may in part be plagued with obesity and obesity related diseases due to a diet enriched with glucose. With an increasing glycemic index observed in Western society, it comes to no surprise that obesity, diabetes, heart disease, and other obesity related diseases are on the rise. The Centers for Disease Control and Prevention describes obesity as an epidemic, affecting more than 35% of U.S. citizens. Shortened lifespan and increased susceptibility to pathogens are associated with these diseases and linked …

The Environmental And Health Costs Of Alternative Diets: A Comparative Study Of The U. S. Diet Relative To The French, Japanese, Mediterranean, And Nordic Diets, Sarah Rehkamp

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This thesis contributes to the literature on sustainable consumption by using scenario analysis to evaluate the environmental and health costs of the U.S. diet relative to the French, Japanese, Mediterranean, and Nordic diets, identified in the literature as healthier diets. As a first step in estimating environmental costs, the energy efficiencies of each diet are calculated by decomposing each of the diets into their respective components. Then, the dietary efficiencies are translated into CO₂ emissions. As a first step in estimating health costs, a pooled cross-section time-series dataset is used to find the association between BMI and five countries, …

The Percussionist Bodybuilder: Optimizing Performance Through Exercise And Nutrition, Anthony Joseph Merlino

UNLV Theses, Dissertations, Professional Papers, and Capstones

Do preventive therapies have the potential to help avoid common injuries among percussionists? This document investigates physiological therapy and nutrition in relation to percussion performance. My interest in this subject matter is derived from my personal experiences with injuries related to the performance of percussion. Although I have studied and played percussion professionally for more than a decade, I was unaware of certain methods of rehabilitation that were available to me prior to my injuries. As I learned about the rehabilitation process through first hand experience, I discovered that my injuries were very common among percussionists. This raised the question: …

Using The Stable Carbon And Nitrogen Isotope Compositions Of Vervet Monkeys (Chlorocebus Pygerythrus) To Examine Questions In Ethnoprimatology, James E. Loudon, J. Paul Grobler, Matt Sponheimer, Kimberly Moyer, Joseph G. Lorenz, Trudy R. Turner

All Faculty Scholarship for the College of the Sciences

This study seeks to understand how humans impact the dietary patterns of eight free-ranging vervet monkey (Chlorocebus pygerythrus) groups in South Africa using stable isotope analysis. Vervets are omnivores that exploit a wide range of habitats including those that have been anthropogenically-disturbed. As humans encroach upon nonhuman primate landscapes, human-nonhuman primate interconnections become increasingly common, which has led to the rise of the field of ethnoprimatology. To date, many ethnoprimatological studies have examined human-nonhuman primate associations largely in qualitative terms. By using stable carbon (δ¹³C) and nitrogen (δ¹⁵N) isotope analysis, we use quantitative data …

Thirty healthy resistance-trained individuals participated in this study (mean ± SD; age: 24.1 ± 5.6 yr; height: 171.4 ± 8.8 cm; weight: 73.3 ± 11.5 kg). Subjects were randomly assigned to one of the following groups: Control (CON) or high protein (HP). The CON …

Exercise And Diet Program For The College Student, Brooks Briel

Senior Theses

Oftentimes college students can be seen going to the gym with simply no direction in exercise or nutrition. They go through the motions of exercising, but have no real understanding of what they are doing. These students may see some progress, but plateau early and find it discouraging to continue to workout. The goal of this project was to create a personal diet and exercise program that could be used by the average college student to improve their physical fitness levels. The exercise program attempts to improve body composition, cardiovascular fitness, muscular strength and endurance, and flexibility. This is done …

The Examination Of Healthy Eating Across Cultures: An Existential Phenomenological Approach, Sarah K. Simpson

Honors College Theses

Adhering to a healthy eating plan has been a topic of discussion across World regions. Moreover, Americans often attempt to mimic the eating habits of other regions of the world, such as the Mediterranean or Eastern Asia, in an attempt to live a long and healthy life. Satia et al., (2000) suggest that healthy eating perceptions can be influenced by food and beverage exposure, family norms, preparation methods, and geographic locations. Although this is the case, little research has been found which has examined healthy eating perceptions across regions from a qualitative perspective. Thus, the purpose of this study is …

Diet And Exercise Interventions Following Coronary Artery Bypass Graft Surgery: A Review And Call To Action, Garrett N. Coyan, Katherine M. Reeder

College of Nursing Faculty Publications

Coronary artery bypass graft (CABG) surgery has been used for the treatment of coronary artery disease (CAD) for approximately 50 years, and has been performed on millions of people globally. However, little is known about the impact of diet and exercise on long-term outcomes of patients who have undergone CABG surgery. Although clinical practice guidelines on the management of this patient population have been available for approximately 2 decades, evidence regarding secondary prevention behavioral interventions, lifestyle modifications and self-management to slow the progressive decline of CAD, reduce cardiac hospitalizations, and prevent reoperation remains virtually absent from the literature. Diet and …

Zutrition: Analyzing And Evaluating Diets Fed To Captive Mammals At Capron Park Zoo, Briell M. Dzierga

Senior Honors Projects

Zoos provide both experiential and educational opportunities for the general public to learn about animals found in a variety of habitats around the world. A successful zoo must provide a safe and enjoyable environment for the visitors, in addition to the species living within the enclosures. Animal husbandry and welfare are crucial aspects to which close attention must be paid, and zoos have a responsibility to attempt to approximate the captive species’ natural habitats and life histories. An essential part of maintaining a captive zoo animal’s health and wellbeing is providing the animal with an appropriate diet. In addition to …

Research is needed to identify factors that inhibit or promote healthful behaviors.

Objective: To determine 1) if there is an association between having a meal plan and selected dietary behaviors, and 2) whether the likelihood of using the campus shuttle and taking the stairs is associated with physical activity.

Methods: Students enrolled in an introductory anatomy class completed a voluntary online survey that assessed …

Socioeconomic Status And Weight Loss Behaviors, Hannah Seward

Theses and Dissertations

In the United States and many other countries, obesity is viewed as a public health crisis that must be handled. Many social and individual solutions to the problem are proposed in research and policy. On an individual level, many Americans try to get rid of their fat with a multitude of weight loss practices as part of a healthy lifestyle. Obesity rates, feelings towards fatness, and weight control behaviors are significantly affected by a number of sociocultural factors. In this project I explore the relationship between the desire to lose weight and weight control practices with income. Using data from …

To accomplish this, a survey with 19 participants, age ranging from 25 to 74 years, was taken for people who attempted Weight Watchers, a calorie-restricted diet, and Atkins, a low-carbohydrate diet. The success rates of each of these diets will be compared and analyzed in this study. Participants reported short-term and long-term weight loss results. For the data analysis, descriptive statistics and two independent t-tests were performed. For short-term weight loss on Atkins, M = 20.25, and on Weight …

Obesity And Dining Out: An Exploration Of Dietary Trends In Urban Malaysia, Sylvia S. Lim

USF Tampa Graduate Theses and Dissertations

Economic growth has spurred rapid urbanization in Malaysia and triggered changes in diet, lifestyle, and disease trends. National studies show that a third of Malaysia's population is overweight/obese while household expenditures on dining out grow. In metropolitan Kuala Lumpur (KL), residents navigate concepts of nutrition, body weight, and health as they dine out. Using the biocultural framework, this study examined links between body weight, diet, income, street food consumption, and nutritional knowledge through the perspectives of consumers and vendors. Altogether, 77 participants were recruited for this three-phase research. In the first phase, a survey was administered to 60 participants recruited …

A Dyadic Analysis Of Couple Attachment Behaviors As Predictors Of Dietary Habits And Physical Activity Levels, Stephanie Young

Theses and Dissertations

While there is substantial evidence that marriage impacts health, no studies have explicitly analyzed the association between attachment behaviors and health practices. This study examines the relationship between couples' attachment behaviors and health practices, as measured by physical activity levels and dietary habits. Couple data was analyzed from the RELATE database (n= 4,957 couples). An Actor Partner Interdependence Model, using a multinomial logistic regression, was used to examine the relationships between attachment behaviors and health practices, as measured by activity level and dietary habits. Results for actor paths indicate that wives' own attachment behaviors significantly influence their own health practices. …

2014 Awards for Excellence in Student Research and Creative Activity Documents

The World Health Organization (WHO) has declared obesity as a global epidemic, estimating 2.3 billion people will be overweight, and 700 million people will be obese by 2015. With the rise in obesity, weight-loss programs are one avenue that consumers are using to battle the epidemic. Approximately 2/3 of adults in the Western population are trying to lose weight or avoid weight gain.

The purpose of this paper is to review the current research of four major weight-loss programs: Weight Watchers, Jenny Craig, Nutrisystem, and Medifast, regarding fundamentals of the programs, the programs safety for consumers use, effectiveness of the …

A Head Start Farm To Family Pilot Program Increased Fruit And Vegetable Intake Among Families, Carmen J. Byker, Courtney A. Pinard, Susan F. Clark, Elena L. Serrano

Journal of Human Sciences and Extension

Fresh Produce, Fresh Start was a pilot farm to family study which tested the effectiveness of a local produce delivery program on dietary intake of Head Start participants. Utilizing a pre-test/post-test design, measures collected from Head Start parents included 24-hour recall of dietary intake, height and weight, and a food security questionnaire. Intent-to-treat analysis was conducted using paired t-tests. Significant increases were found in intake of vitamin A, vitamin C, fiber, vegetable, and fruit and vegetable servings combined (p < .05) for participants (N = 51). In particular, fruit and vegetable intake increased by 1.4 servings per day. Food security status and weight status did not significantly change. Results indicate that a produce delivery program has potential to improve dietary intake of Head Start families and, possibly, other populations, impacting lifelong consumption habits

Health Capabilities And Diabetes Self-Management: The Impact Of Economic, Social, And Cultural Resources, Robert Weaver, Manon Lemonde, Naghmeh Payman, William M. Goodman

College of Science & Mathematics Departmental Research

While the “social determinants of health” view compels us to explore how social structures shape health outcomes, it often ignores the role individual agency plays. In contrast, approaches that focus on individual choice and personal responsibility for health often overlook the influence of social structures. Amartya Sen's “capabilities” framework and its derivative the “health capabilities” (HC) approach attempts to accommodate both points of view, acknowledging that individuals function under social conditions over which they have little control, while also acting as agents in their own health and well-being. This paper explores how economic, social, and cultural resources shape the health …

How Important Is Land-Based Foraging To Polar Bears (Ursus Maritimus) During The Ice-Free Season In Western Hudson Bay? An Examination Of Dietary Shifts, Compositional Patterns, Behavioral Observations And Energetic Contributions, Linda J. Gormezano

Dissertations, Theses, and Capstone Projects

Trophic mismatches between predators and their prey are increasing as climate change causes decoupling of phenological relationships. Predators linked to the life histories of a particular prey will have a more difficult time persisting through environmental change unless they can alter their behavior to maintain the historical match or possess the ability to pursue alternate prey. Arctic predators typically possess flexible foraging strategies to survive in the labile environment, however, quantifying the limits of those strategies can be difficult when life history information is incomplete. In such cases, piecing together different aspects of a predator's foraging behavior, particularly when environmental …

Plasma Selenium Biomarkers In Low Income Black And White Americans From The Southeastern United States, Margaret K. Hargreaves, Jianguo Liu, Maciej S. Buchowski, Kushal A. Patel, Celia O. Larson, David G. Schlundt, Donna M. Kenerson, Kristina E. Hill, Raymond F. Burk, William J. Blot

Public Health, Health Administration, and Health Sciences Faculty Research

Biomarkers of selenium are necessary for assessing selenium status in humans, since soil variation hinders estimation of selenium intake from foods. In this study, we measured the concentration of plasma selenium, selenoprotein P (SEPP1), and glutathione peroxidase (GPX3) activity and their interindividual differences in 383 low-income blacks and whites selected from a stratified random sample of adults aged 40–79 years, who were participating in a long-term cohort study in the southeastern United States (US). We assessed the utility of these biomarkers to determine differences in selenium status and their association with demographic, socio-economic, dietary, and other indicators. Dietary selenium intake …

Influence Of Diet And Obesity On Copd Development And Outcomes, Corrine K. Hanson, Erica P. Rutten, Emiel F.M. Wouters, Stephen I. Rennard

Journal Articles: Pulmonary & Critical Care Med

The global increase in the prevalence and incidence of obesity has called serious attention to this issue as a major public health concern. Obesity is associated with many chronic diseases, including cardiovascular disease and diabetes, and recently the role of overweight and obesity in lung disease has received new interest. Independently of obesity, diet also plays a role as a risk factor for many chronic diseases, and evidence is accumulating to support a role for diet in the prevention and management of several lung diseases. Chronic obstructive lung disease is the third-leading cause of death globally, and both obesity and …

Relationships Between Diet, Exercise And Learning In The Regular Science Classroom Setting, Joseph R. Sieracki

ETD Archive

The purpose of this study is to examine how diet and exercise relate to student achievement and learning in the regular classroom setting. Research questions include whether or not there is a positive correlation between the amount/type of exercise a student receives per week and learning, as well as relationships between their diet and learning in the classroom. Forty high school honors biology students were surveyed as to their dietary and exercise habits. This data was compared to their individual average test grades as a measure of learning
