The Impact Of The Updated National School Lunch Program Meal Standards On Fruit And Vegetable Consumption Among Elementary School Students In Cache County Utah, Jillian C. Fox

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Due to the short time the updated National School Lunch Program standards have been in place since fall of 2012, few research studies have explored what effect these new standards have had on fruit and vegetable (F/V) consumption, particularly among elementary school students. Because the new standards require schools to offer students more F/V than before, researchers are interested to know if F/V consumption has indeed increased.

The participants in the study were enrolled in a program to motivate students to eat more F/V – the Food Dudes program. The results of the data analysis found that most students, regardless …

Examining The Association Between Children's Fruit And Vegetable Intake At And Away From School, Velarie Yaa Ankrah Ansu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Several school-based interventions aimed at increasing fruit and vegetables (FV) intake among children have demonstrated success in short-term interventions. The Fit Game is a school-based intervention aimed at encouraging children to consume increasing amounts of FV during a game, which is a narrative. Just as children are being encouraged to eat FV at school, so is it equally important for them to eat FV at home. Parents strongly influence the amount of FV children consume at home. The aim of this thesis is to examine associations between factors that influence consumption of fruits and vegetables at and away from school …

Contribution Of A Novel Obligatory Heterofermentative Nonstarter Lactobacillus Species To Late Gassy Defect In Cheddar Cheese, Fatih Ortakci

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cheddar cheese is usually aged for 3 to 24 months at temperatures ranging from 5 to 13°C. Ripening at elevated temperatures hastens the process, reducing manufacturing costs and enabling manufacturers to bring the product to market more quickly. However, cheeses ripened at elevated temperatures sometimes exhibit late gassy defect that may cause a textural defect, commonly referred to as slit defect. This results in crumbling and
losses during cutting of as much as 50%, making slit defect a major economic issue in the cheese industry. Moreover, loose or blown cheese packages are unsuitable for sale in the supermarkets due to …

Implementation Of Online Tutoring Program To Increase University Student Information Retention, April Litchford

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis discusses an online tutoring program, MasteringNutrition©, that was implemented as a required portion of an entry level collegiate nutrition course. The tutoring program was introduced to test the ability of the program to improve memory of nutrition information taught during the course. The MasteringNutrition© program combines various teaching techniques that have been successful in increasing student learning. The major techniques discussed include: Socratic questioning, metacognition, and problem based learning. These techniques are incorporated into the MasteringNutrition© program.

To test the effect of the Mastering© tutoring program, ten questions specific to course learning objectives were asked of students in …

Effect Of High Intensity Ultrasound On Crystallization Behavior And Functional Properties Of Lipids, Yubin Ye

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The elimination of trans-fatty acids from food formulations has resulted in the search of new lipids and novel processing conditions that can provide optimum functional properties in fats while providing good nutritional properties. High intensity ultrasound (HIU) has been extensively studied on sonocrystallization of lipids since early 2000. Sonocrystallization refers to the induction of crystallization by HIU without generating any chemical changes. This dissertation aims to provide information on the effects of HIU on crystallization behavior and physical properties of different shortenings based on previous sonocrystallization research. Results in this dissertation showed that HIU successfully induced the crystallization of …

Investigation Of Sugar/Polyols As Weakly Interacting Cosolvents And Their Influence On Hardening Of High-Protein Nutrition Bars, Sami Kadhim Hassan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Western Dairy Center (WDC) at Utah State University demonstrated opportunities to improve the quality of high-protein snack foods that becoming more prevalent in western diets. Previously, such high-protein nutrition bars became too hard during storage and they had a limited shelf life, resulting in disappointment by consumers or loss of product as older products needed to be discarded.

With sponsorship as a doctoral student by the Iraq Ministry of Higher Education and Scientific Research and in conjunction with WDC researchers, an investigation was conducted into the chemistry of high-protein nutrition bars and how the various components (protein, carbohydrate and …

The Effects Of Social Norms Feedback On Fruit And Vegetable Consumption And Skin Carotenoids Among College Students, Troy A. Bailey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fruit and vegetable consumption, which has been shown to have a protective effect against chronic diseases, often decreases during the first few years of college. Implementing public health interventions to improve consumption of these foods may be time-consuming, costly and burdensome. The aim of this study was to determine if a social norms intervention, examining the effects of normative and manipulated feedback of participants’ carotenoid scores compared to a no-norm control, could increase fruit and vegetable consumption among college students. Such a strategy could be a cost-effective method for promoting healthy diets in this population.

While self-reported increases in fruit …

Analysis Of Quality Of Two Different Varieties Of Peaches With Respect To Organic And Conventional Cultivation Techniques, Shruti D. Sawant

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The worldwide demand for organic produce has been on the rise in recent years. This is a result of consumer concerns about the environment and chemicals used in food production. In addition, consumers have demonstrated that they are willing to pay premium prices for organic produce based on the general assumption that organic produce is more nutritious, environmentally friendly, and better-tasting. There have been several studies that have reported significant differences with organic and conventionally grown produce. Organic fruits and vegetables have been shown to have higher dry matter, antioxidants. In addition, it has also been shown to be smaller …

Pregenomic And Genomic Effects Of 24,25-Dihydroxyvitamin D3, Yang Zhang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the United States, the major dietary source of protein is poultry meat, particularly chicken. Phosphorus absorption in chickens is a critical problem in poultry production. It therefore is important to understand the cellular and molecular regulation of phosphorous absorption in intestine to increase efficiency of the process. This would provide the benefits of reducing feed costs and reducing phosphorous excretion, thereby contributing to the sustainability of agriculture in the United States. Therefore, the focus of this thesis is determining the effect of vitamin D metabolites involved in phosphate homeostasis using the chicken as a model.
