Comparative Nutritional Assessment And Metabolomics Of A Wrky Rice Mutant With Enhanced Germination Rates, Santiago Bataller, Anne J. Villacastin, Qingxi J. Shen, Christine Bergman

Life Sciences Faculty Research

Rice is the primary staple food for half the world’s population. Climate change challenges and food insecurity supports the need for rice with agronomically advantageous traits. We report on a transposon insertional rice mutant with enhanced germination rates. This trait is advantageous for rice growth in limited water regions and to reduce yield constraints caused by weed and bird competition. Evaluations of vital nutritional components, compositional analysis, and comparative metabolomics on threshed grain samples are performed, as these assays are those used to assess the safety of foods from genetically modified crops. Compared with the wild type (cv. Nipponbare), oswrky71 …

Is Dietary Teaching Via Telehealth Effective In Lowering Hgba1c In Adult Patients With Prediabetes Or Type 2 Diabetes?, Mia Mccallum-Crawford

UNLV Theses, Dissertations, Professional Papers, and Capstones

Prediabetes and Type 2 diabetes mellitus (T2DM) are two common conditions diagnosed in the primary care setting. Both conditions benefit from a healthy lifestyle, managing blood sugar levels, and getting diabetes self-management education and support (DSMES). Within the past two decades, the healthcare community in the US has witnessed a substantial rise in diabetes among adults. Overall, the self-management of diabetes continues to worsen nationally. The purpose of this project is to improve patients’ self-management of both Prediabetes and T2DM through nutrition and show how nutritional counseling via telehealth provided by a nurse practitioner can improve HgbA1C values over 3 …

The aim of this observational study was to determine the difference in dietary intake between food insecure and food secure individuals with type 2 diabetes, as well as by glycemic control. Methods In this cross-sectional study, 55 participants were recruited from an academic endocrinology clinic. Participants completed a 7-day food diary, a household food security questionnaire, and assessment of blood biomarkers (HbA1c). To determine the differences …

Fruit And Vegetable Consumption Behavior Among Asian Americans: A Thematic Analysis, Chia Liang Dai, Manoj Sharma, Taj Haider, Hema Sunchu

Teaching and Learning Faculty Research

© The Author(s) 2021. Consuming 5 or more cups of fruits and vegetables (F & V) per day or 400 g/day for adults is advocated by most health authorities and has short-term and long-term health benefits. There have been numerous studies examining dietary behaviors among different US populations; however, the literature on F & V consumption behavior among Asian Americans (AAs) is sparse. AAs constitute a diverse group and as their population continues to grow in the US; there is a greater need to examine the health practices of AAs and their constituent subgroups. The study aimed to conduct a …

Investigation Of Acute Response To Carbohydrate In Subsequent Resistance Training, Damon Mccune

UNLV Theses, Dissertations, Professional Papers, and Capstones

Resistance training has been shown to have several positive benefits to health including increasing muscle size and strength, reducing risk of sarcopenia with aging, and is associated with reduced risk of mortality. A cornerstone in accomplishing these goals is to progressively overload the muscle by increasing training volume to promote muscle protein synthesis following training stimulation. Total training volume has been demonstrated in the literature to be a prime determinant of muscle hypertrophy and overall training performance. Carbohydrate (CHO) manipulation has been observed as a potential ergogenic aid when training demands are high. Current research investigating nutrition related to exercise …

Kinesiology and Nutrition Sciences Faculty Publications

In this Position Statement, the International Society of Sports Nutrition (ISSN) provides an objective and critical review of the literature pertinent to nutritional considerations for training and racing in single-stage ultra-marathon. Recommendations for Training. i) Ultra-marathon runners should aim to meet the caloric demands of training by following an individualized and periodized strategy, comprising a varied, food-first approach; ii) Athletes should plan and implement their nutrition strategy with sufficient time to permit adaptations that enhance fat oxidative capacity; iii) The evidence overwhelmingly supports the inclusion of a moderate-to-high carbohydrate diet (i.e., ~ 60% of energy intake, 5–8 g·kg− 1·d− 1) …

Socio-Ecological Wellness Wheel: Applied To Community Gardens To Measure Green Gentrification, Micajah Daniels, Courtney Coughenour

McNair Poster Presentations

This project is intended to use Black Feminist Health Studies as an interdisciplinary approach to analyze the holisitc impacts of community gardens on nutrition behaviors. The implementation of green spaces such as community gardens have been correlated to both benefits and unintended consequences which this study demonstrates through the Socio-Ecological Wellness Wheel. An empirical and systematic way of measuring garden quality through an audit tool using Black Feminist Health Studies could help measure the nutrition environment of the community gardens and how they may influence fruit and vegetable consumption of food insecure populations. The need for this study is highlighted …

Understanding Perceptions Of Genetically Modified Food Among Natural Food Shoppers In Southern Nevada, Christian Murua-Aceves

UNLV Theses, Dissertations, Professional Papers, and Capstones

Today, 85% of corn, 93% of soybeans, and 88% of cotton in the U.S. are genetically modified (GM). Using laboratory methods, genes from one species, such as a plant, can be transferred to an unrelated species, such as an animal. Genetically modified crops may lead to higher yields, have improved food quality, texture, and nutritional value, and have an increased shelf life.

Despite these promising benefits, the potential health risks relating to the consumption of GM food remain inadequately assessed. Genetically modified food is not subjected to rigorous safety testing, such as epidemiologic studies, to identify potential health risks. Two …

Evaluation Of The Relationship Between Nutrition Knowledge And Disordered Eating Risk In Female Collegiate Athletes, Amy L. Miracle

UNLV Theses, Dissertations, Professional Papers, and Capstones

Involvement in collegiate sports among female athletes is at an all-time high with approximately 198,000 currently participating, (National Collegiate Athletic Association, 2012). With this increase in female participation in collegiate sports, the pressures of sport participation and academics lead some women to engage in harmful eating behaviors. These harmful eating behaviors may lead to the development of disordered eating (C. Johnson, Powers, & Dick, 1999; Quatromoni, 2008; Reel, SooHoo, Petrie, Greenleaf, & Carter, 2010; Reinking & Alexander, 2005). Many factors have been identified as contributing to the development of disordered eating but nutrition knowledge or lack thereof, has yet to …

Findings From The Nutrition Challenge Program, Rayleen Earney, Nicole Bungum, Timothy J. Bungum

Nevada Journal of Public Health

Obesity is an epidemic in the United States. Over 61% of U.S. adults and 58% of Nevada adults have Body Mass Index’s (BMI) that classify them as either overweight or obese (Behavioral Risk Factor Surveillance System [BRFSS], 2005). According to a recent article published in the Journal of the American Medical Association, obesity was the second leading cause of preventable death in the United States behind tobacco use (Mokdad, Marks, Stroup & Gerberding, 2004).

While obesity and overweight are complex, multi-factorial health conditions, an important contributor to the overweight and obesity epidemic is poor dietary habits. One of the major …
