“I Am A Vegetarian”: Reflections On A Way Of Being, Kenneth J. Shapiro

Kenneth J. Shapiro, PhD

Employing a qualitative method adapted from phenomenological psychology, the paper presents a socio-psychological portrait of a vegetarian. Descriptives are a product of the author’s reflection on (dialogue with) empirical findings and published personal accounts, interviews, and case studies. The paper provides evidence for the hypothesis that vegetarianism is a way of being. This way of experiencing and living in the world is associated with particular forms of relationship to self, to other animals and nature, and to other people. The achievement of this way of being, particularly in the interpersonal sphere, comprises an initial, a transitional, and a crystallizing phase …

Brown And Beige Adipocytes: Effects Of Inflammation And Nutritional Intervention, Jiyoung Bae

Doctoral Dissertations

Recent findings of brown adipocytes and brown-like or beige adipocytes, capable of dissipating energy as heat, in adult humans have promised new hope for obesity treatment and prevention. Understanding of the regulation of brown and beige adipocytes will provide novel strategies to reach the goal. Pattern recognition receptors (PRR) are responsible for inflammation in adipose tissue, which leads to adipose dysfunction and obesity associated chronic diseases. It has been shown that PRR activation induces inflammation, leading to insulin resistance in white adipocytes and white adipose tissue (WAT). However, the roles of PRR activation in brown adipocytes and brown adipose tissue …

Educated Birth: Beliefs Vs. Outcomes, Lauren Presley

Human Nutrition and Hospitality Management Undergraduate Honors Theses

“Our infant mortality rate is a national embarrassment.”¹ The words seem shocking and harsh across the headline of a 2014 Washington Post article. The thought of America not only not being the best at something, but falling upsettingly behind, is a foreign concept to many who view America as a nation inferior to none. However, the statistics on infant mortality rate tell the stark truth that of 26 “wealthy” countries, the U.S. ranks last, with a sobering 6.1 deaths per 1,000 live infant births.²

Part of the Healthy People 2020 Objectives is to reduce the rate of infant …

However, residual effects of these manures on voluntary intake of forages from subsequent harvests are not well known. The objectives of this two part study were to determine if moisture level of alfalfa silage and the use of dairy slurry as a fertilizer have an effect on intake and digestibility by sheep, and if forage species and the use of poultry litter as a fertilizer have an effect on intake by horses. Eighteen ewes (47.6 ± 5.34 kg) were used in experiment 1 and were …

Stability Of Whole Wheat Flour, Rolled Oats, And Brown Rice During Long-Term Storage And Preparation, Victoria Elizabeth Scott

Theses and Dissertations

Whole grains are an increasingly popular health food in America. However, shelf life of whole grains is compromised due to the presence of lipoxygenases in the bran and germ, which lead to rancidity and generation of oxidative byproducts. These byproducts reduce sensory quality and may have a degradative effect on vitamins in whole grain products. The purpose of this study was to determine the degree of lipid and vitamin degradation during long-term storage of three whole grains: whole wheat flour, brown rice, and rolled oats. We also examined vitamin loss after cooking to determine if oxidative byproducts had an effect …

Hospital Practices Related To Breastfeeding In Mississippi: A Socio-Ecological Approach, Amir Alakaam

Dissertations

Mississippi continues to have one of the lowest rates and the weakest support in respect to breastfeeding in the nation (Centers for Disease Control and Prevention, 2014a). Hospital practices supporting breastfeeding such as the Ten Steps to Successful Breastfeeding (TSSB) can dramatically increase breastfeeding rates and duration (Rosenberg, Stull, Adler, Kasehagen, & Crivelli-Kovach, 2008). The aim of this study was to explore breastfeeding practices in Mississippi hospitals based on two levels of the Socio-Ecological Model: the organizational level (phase I) examined the hospital practices based on the level of implementation of the TSSB; the individual level (phase II) examined knowledge …

The obesity epidemic continues to be a problem both in the US and worldwide. A number of factors have been attributed including: frequency of fast-food consumption, increased portion sizes, increased consumption of sugar-sweetened beverages, increased sedentary lifestyles, lack of nutrition knowledge, and lack of cooking skills. Nutrition intervention programs continue to be created providing innovative and creative ways of educating the public with pertinent knowledge and skills necessary for improving healthful behaviors; however, few programs focus on cooking skill development within a familial environment. The Generations Eating Together Through Cooking (G.E.T.T. Cooking) program was created by the lead researcher as …

Web-Based Nutrition Education Intervention For African American Women Using The Theory Of Planned Behavior, Joyce Senior Angulo

All Dissertations

African American women have been disproportionately impacted for decades by the obesity epidemic, which frequently leads to severe chronic diseases such as cardiovascular disease, diabetes and hypertension. This increase in chronic diseases amongst African American women is the motivation for the design of a culturally tailored nutrition education (NE) program that combines a strong theoretical base with the use of technology such as the Internet, since its usage within the college aged African American community has rapidly increased. Little is known about the variables that motivate behavior change in regards to eating and physical activity habits among college aged African …

Digestibility Of Two Complete Pelleted Diets By The Horse (Equus Caballus) As A Model Animal For Nondomestic Hindgut Fermenters, Emily M. Schwartz

Master's Theses

Estimating nutrient and energy requirements of exotic animals is a necessary component of nutrition management in zoos and other wildlife facilities. In the absence of species-specific data, domestic animal models are often referenced. Herbivorous hindgut fermenters, such as horses, zebra, and rhinoceros, rely on microbial fermentation in the cecum and colon to utilize dietary structural carbohydrates. The study objective was to measure the digestible energy of two (LOW, HIGH) complete pelleted diets by the horse as a model for nondomestic hindgut fermenters. Seven, individually housed, adult Quarter Horse (Equus caballus) geldings were assigned to one of two diets as 100% …

Folate Stability In Fortified Corn Masa Flour, Tortillas, And Tortilla Chips, Renee Phillips

Theses and Dissertations

Neural tube defects (NTDs) occur at higher rates in Hispanic populations in the USA. Such populations would benefit from folic acid fortification of corn masa flour (CMF). This study evaluated folate stability in fortified CMFs and products made from the flours, tortillas and tortilla chips. There was no significant loss of folate during the six-month shelf-life of fortified tortilla CMF and tortilla chip CMF. There was a 13% loss (P < 0.05) of folate during tortilla baking and no loss during tortilla chip frying. Both tortillas and tortilla chips showed significant folate losses over the two-month shelf-life for these products, with a 17% loss in fortified tortillas and 9% loss in tortilla chips. Folate in fortified CMFs, tortillas and tortilla chips is relatively stable and comparable to the stability of folate in wheat flour and breads.

Television Consumption And Child Obesity: Linking Children's Contemporary Television Use, Physical Activity, And Advertising To Putnam's Displacement Hypothesis, Brittany L. Altamirano

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study observed the relationship between television consumption and child obesity through the theoretical construct of Putnam’s displacement hypothesis. It did so by updating the previous research through the investigation of the displacement of both physical activity and advertisements on contemporary television platforms. The inclusion of Putnam’s displacement hypothesis was to provide a foundational framework, not found in previous literature, to study two important paradigms that were represented in previous research: 1) the displacement of physical activity; and 2) the displacement of traditional advertisement exposure.

Several trends became apparent within previous literature. Previous literature did not include an explicitly stated …

According to the Massachusetts Department of Public Health, education and income levels of Springfield residents are well below state averages, and racial diversity in Springfield has increased significantly over the past few decades. Springfield’s demographics increase the risk of health disparities in the community, and higher rates of diabetes, heart disease, and obesity are seen in Springfield. To promote healthy eating behaviors among Springfield residents, Mason Square Health Task Force (MSHTF), a Live Well Springfield (LWS) partner, created a …

Association Of Dietary Factors With Menstrual Cycle Characteristics, Radhika Natarajan

Doctoral Dissertations

Abnormal menstrual cycle length, pattern and bleed duration are associated with reduced fecundity and increased risk of miscarriage. The menstrual cycle is governed by the hypothalamus-pituitary-ovarian (HPO) axis, and nutritional factors may affect menstrual characteristics by influencing the HPO axis. Identifying these factors may lead to cost effective ways to improve reproductive outcomes. In a cross-sectional analysis of 164 18- to 30-year-old women, we examined the association of adiposity, dietary fat intake and vitamin D status with menstrual cycle characteristics. Adiposity was measured using dual-energy X-ray absorptiometry (DXA); dietary intake was assessed using a food frequency questionnaire, and fasting venous …

Gestational Diabetes, Infant Feeding Practices, And Early Indicators Of Obesity Risk In A Sample Of Mother-Infant Dyads In The U.S., Kimberly N. Doughty

Doctoral Dissertations

Research suggests that the trajectory to obesity and its associated metabolic disorders begins early in life. Prenatal exposure to maternal gestational diabetes mellitus (GDM) is associated with increased risk, while breastfeeding is associated with reduced risk. Breastfeeding may influence obesity risk by preventing rapid postnatal weight gain. Mothers with gestational diabetes may not breastfeed as intensely as healthy mothers, potentially exacerbating the risk to their infants. We conducted three distinct investigations related to gestational diabetes, breastfeeding, and infant weight gain. All used data from the U.S. Infant Feeding Practices Study II. Multivariate logistic regression was used to estimate associations between …
