Whole Egg Consumption Attenuates Weight Gain In Obese Type 2 Diabetic Rats, Kaylee Hahn, Caitlyn Coonts, Carter Reed 2017 Iowa State University

Whole Egg Consumption Attenuates Weight Gain In Obese Type 2 Diabetic Rats, Kaylee Hahn, Caitlyn Coonts, Carter Reed

Symposium on Undergraduate Research and Creative Expression

Obesity is a national epidemic that can increase an individual's risk for a multitude of health complications, including type 2 diabetes (T2D). In individuals already diagnosed with the disease, even small amounts of weight loss can help prevent diabetic complications. Due to the relationship between obesity and T2D, and the link between obesity and diet, a better understanding of how dietary factors affect those with T2D is necessary. Currently, the consumption of whole eggs by those with T2D is controversial. Here, we investigated the relationship between the consumption of whole eggs and obesity in both a genetic-mediated and diet-induced ...


The Long Haul: Migratory Flight Preparation And Performance In Songbirds, Morag F. Dick 2017 The University of Western Ontario

The Long Haul: Migratory Flight Preparation And Performance In Songbirds, Morag F. Dick

Electronic Thesis and Dissertation Repository

Migration requires birds to sustain high intensity endurance exercise for periods lasting from hours to days. Similar to athletes, preparation and nutrition is key to success. Birds seasonally prepare for migration, which includes increasing the capacity to oxidize fat in the flight muscles. Beyond fuelling migration, n-3 long-chain polyunsaturated fatty acids (PUFA) are hypothesized to be natural doping agents and increase endurance and fatty acid oxidative capacity. I examined how birds prepare for and sustain migratory flight and directly tested the role of n-3 PUFA. Using yellow-rumped warblers (Setophaga coronata) as a model species, I first examined the effects of ...

Early Nutritional Programming To Enhance The Utilization Of Plant Based Diets In Fish (Largemouth Bass, Micropterus Salmoides), Maya Rene Jackson, Cora Teets, Amit Kumar Yadav, Waldemar Rossi

Posters-at-the-Capitol

Aquaculture has been the fastest growing animal food-producing sector for over half a century. Sustainable aquaculture should include replacement of fish-based feed sources by plant-based ingredients. However, this approach is often impeded by poor growth in carnivorous fish such as largemouth bass (LMB, Micropterus salmoides) fed high levels of plant-based protein. Therefore, our overall goal of the present work was to develop alternative methods of utilizing the plant-based diets (PBD) for sustainable LMB production. When fish is exposed to PBD early in their life, they may accept them more efficiently at later stages (so called Nutritional Programing, NP). Therefore, we ...

Master's Theses and Project Reports

Particle size distribution of diet, feces, and change from diet to feces, as well as apparent digestibility (aDig, %) of selected nutrients, and novel fecal microbiome identification of mature female leopard tortoises (Stigmochelys pardalis, n = 16) fed exclusively one of three, nutritionally complete, pelleted diets were evaluated in a blind, complete randomized design study. Two diets included insoluble fiber (powdered cellulose) consisting of either 2.0 mm or 0.2 mm length. Insoluble fiber provides nutritional and physical benefits to both the animal host and the microorganisms that inhabit the gastrointestinal tract. Insoluble fiber length was used as a means of ...


Characterization Of Extraction Methods To Recover Phenolic-Rich Extracts From Black Beans (Phaseolus Vulgaris) That Inhibit Alpha-Amylase And Alpha-Glucosidase Using Response Surface Approaches, Mazen Alharbi 2016 University of Nebraska-Lincoln

Characterization Of Extraction Methods To Recover Phenolic-Rich Extracts From Black Beans (Phaseolus Vulgaris) That Inhibit Alpha-Amylase And Alpha-Glucosidase Using Response Surface Approaches, Mazen Alharbi

Nutrition & Health Sciences Dissertations & Theses

Black beans contain high phenolic contents that are considered potent antioxidants. Relatively little is known about their ability to inhibit the carbohydrate-hydrolyzing enzymes α-amylase and α-glucosidase from releasing glucose from starch and/or disaccharides. The objective of this project was to determine the optimum procedures for extracting total phenols (TP), total flavonoids (TF) and total condensed tannins (TCT) from black beans (Phaseolus vulgaris), and then to determine the ability of the phenolic rich extracts to inhibit α-amylase and α-glucosidase. Due to their high phenolic levels, it was hypothesized that black beans would be an effective inhibitor of α-amylase and α-glucosidase ...

Evaluation Of Protein Source At Breakfast On Energy Metabolism, Metabolic Health, And Food Intake: A Pilot Study, Lauren A. Cambias

Human Nutrition and Hospitality Innovation Undergraduate Honors Theses

Abstract

Over 30% of adults in the US are obese. A primary contributor to obesity is an unhealthy diet related to imbalanced macronutrients. Diets higher in protein (PRO) are associated with increased energy expenditure (EE) and reduced food intake. The objective of this pilot study was to determine if protein source at breakfast influences EE in young men (n=4; ages 18-35). Participants consumed three isocaloric (whey (WP), pea (PP), beef (BP); 275 kcal, 62% PRO, 23% CHO, 15% Fat) drinks in randomized, crossover design with a one-week washout period. Each test day EE, appetite, and cravings were assessed at ...

Previous studies have shown positive effects of long-term resveratrol (RSV) supplementation in preventing pancreatic beta cell dysfunction, arterial stiffening and metabolic decline induced by high-fat/high-sugar (HFS) diet in nonhuman primates. Here, the analysis was extended to examine whether RSV may reduce dietary stress toxicity in the cerebral cortex of the same cohort of treated animals. Middle-aged male rhesus monkeys were fed for 2 years with HFS alone or combined with RSV, after which whole-genome microarray analysis of cerebral cortex tissue was carried out along with ELISA, immunofluorescence, and biochemical analyses to examine markers of vascular health and inflammation in ...

Black Soldier Fly Larvae Manual, Haeree H. Park

Student Showcase

This manual is a resource for fisheries, hatcheries, and farms of all types that wish to exercise a sustainable management system utilizing black soldier fly larvae through the minimization of waste. Although black soldier fly larvae can be fed to small livestock such as chickens and rodents, this project and manual are tailored specifically to freshwater fish in hopes of closing the significant gap and inefficiencies of fish management and subsequent waste throughout the New England coastal area. There is an evident opportunity to harness black soldier fly larvae’s extraordinary bioconversion of organic matter that can lead to not ...


Digestibility Of Two Complete Pelleted Diets By The Horse (Equus Caballus) As A Model Animal For Nondomestic Hindgut Fermenters, Emily M. Schwartz 2015 California Polytechnic State University, San Luis Obispo

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 and Project Reports

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 ...


Hypohydration And Mood State In Free-Living Males And Females, Thomas Edward Vidal 2015 University of Arkansas, Fayetteville

Hypohydration And Mood State In Free-Living Males And Females, Thomas Edward Vidal

Theses and Dissertations

Previous research has shown that acute dehydration can result in changes in mood. These changes have been reported in less than a 1% loss in total body water. However, the effect of hypohydration (i.e., reflected through high urine concentration) on mood in free-living conditions has not been studied. PURPOSE: The present study was designed to determine if hydration status is associated with mood within the general population under free-living conditions. METHODS: A group of 103 apparently healthy subjects (49 male, 54 female, 41±14 y, 1.7±0.1 m, 76.1±16.9 kg) completed three visits separated ...

Is Fortification Or Bio Fortification Of Staple Food Crops Will Offer A Simple Solution To Complex Nutritional Disorder In Developing Countries?, Mahalingam Govindaraj

Mahalingam Govindaraj

Large segment of global populations, especially in developing countries is currently at risk from one or more micronutrient deficiency, so called malnutrition. This could be due to our current food systems are fail to provide enough balanced dietary nutrients to meet all the nutritional requirements of every individual, especially resource-poor women and children in the developing countries. A variety of interventions have been used to address micronutrient malnutrition so far such as pharmaceutical supplementation, industrial fortifications and dietary diversification. However, success of supplementation and fortification in developing countries remains challenges due to poor infrastructure, delivery system, more often it need ...


Vegetarianism And Virtue: Does Consequentialism Demand Too Little?, Nathan Nobis 2015 University of Rochester

Vegetarianism And Virtue: Does Consequentialism Demand Too Little?, Nathan Nobis

Nathan M. Nobis, Ph.D.

The article discusses the moral aspects of vegetarianism. This will make vegetarians more compassionate and caring for animals and will result in better health and less finances. The virtue theory or the vegetarian justifying principle connotes that one should not support even symbolically bad practices to animals when good alternatives are readily available. Becoming a vegetarian is a way of attesting to the depth and sincerity of one's belief in the wrongness of how we treat animals and its consequence to humans. Consequentialism does not demand too little because it requires that one conforms his behavior to the vegetarian ...


Dietary Habits And Knowledge Of College Age Students, Matthew R. Majors 2015 University of Kentucky

Dietary Habits And Knowledge Of College Age Students, Matthew R. Majors

Theses and Dissertations--Dietetics and Human Nutrition

College is a time of emerging identity and habit formation for students. One hundred and sixty-two (162) college students were surveyed via an internet based survey. The survey asked questions regarding dietary habits such as consumption of dairy, vegetables, fruit, and protein. The survey also examined dietary knowledge such as ability to read food labels. The students were divided into two groups for analysis, nutrition majors and non-nutrition majors. The two groups differed in Body Mass Index (BMI) (p=0.004), but not nutrition knowledge (p=0.082). The nutrition students had an average BMI of 22.0+/-2.42 ...

Microalgae In Eastern Pacific White Shrimp Hatcheries: A Review On Roles And Culture Environments, Wa Iba, Michael Rice, Gary Wikfors

Michael A Rice

Demand for shrimp, particularly the eastern Pacific white shrimp Litopenaeus vannamei (Boone 1931), will continue to increase in Asian and worldwide seafood markets. Providing shrimp farms with a robust, healthy, and continuous supply of shrimp seed is a challenge that must be addressed to meet the demand. Shrimp feed during hatchery production still relies on live microalgae, despite many years of effort to find suitable full or partial-replacement diet alternatives. Successful mass production of microalgae for hatchery feed to obtain good quality shrimp seedstock depends on a number of environmental factors that determine the growth and nutritional values of various ...
