Description
The true number of food borne illness occurrences that stem from the home is largely unknown, but researchers believe the number is much greater than represented in national data. The focus on food safety has generally been directed at food service establishments, which have made great strides at improving the methods of how their food is prepared. However, that same drive for proper food safety education is lacking in home kitchens, where the majority of food is prepared. Young adults are among some of the riskiest food preparers, and limited research and education methods have been tested on this vulnerable population. This study examined the effect of a basic food safety intervention on consumer food safety knowledge in young adults in the United States (U.S.) over a week period. The study had a pre/post survey design, where participants answered a survey, watched a short 10-minute video, and then recompleted the same survey a week later. Ninety-one participants age 18-29 years completed the initial food safety knowledge questionnaire. Twenty-six of those participants completed both the pre- and post-intervention food safety knowledge questionnaires. A paired t-test was used to analyze changes in questionnaire scores pre/post intervention. The majority of participants were female (78.9%), Arizona State University (ASU) students (78.0%), did not have any formal food safety education (58.2%), prepared a minimum of one meal per week from home (96.7%), and had completed 0-1 college nutrition courses (64.8%). The average overall score for all participants who completed the initial questionnaire was 62.6%. For those that took both the initial questionnaire and the follow up questionnaire (n=26), their scores shifted from 66.8% to 65.5% after the intervention. Scores increased significantly only for one question post-intervention: 38.5% (n=10) to 53.8% (n=14) for the safest method for cooling a large pot of hot soup (p = 0.050). This was the first study of its kind to test a video intervention in attempts to increase food safety knowledge in young adults, and additional studies must be done to solidify the results of this study. Other means of education should be explored as well to determine the best way of reaching this population and others.

Description
Chronic diseases, such as diabetes, heart disease, and cancer are leading causes of death in the United States. Although they result from a host of personal and environmental factors, diet remains a critical way to reduce the risk. Plant-based diets in particular are associated with reduction in risk for chronic disease due to an intake that closely mirrors the Dietary Guidelines for fruit and vegetable consumption, fiber, and fat intake. Additionally, plant-based diets offer a sustainable alternative in relation to food production as they often require fewer natural resources overall.
While there are many benefits to following a plant-based diet, potential concerns arise as well. Certain micronutrients can be lacking and protein intake can be inadequate without careful consideration of dietary intake. Protein is especially important for its role in maintaining lean body mass, which allows individuals to function in activities of daily living. Plant-based sources of protein are often less digestible; therefore, those consuming vegetarian and vegan diets may benefit from increased protein intake for preservation and perhaps improved lean body mass as well as strength changes.
Recent research has shown that vegetarians had significantly less muscle mass compared to omnivores despite similar amounts of protein intake in grams per day. Other research has shown that vegetarians do not necessarily see an increase in muscle mass when exposed to resistance exercise, whereas those following an omnivorous diet or lacto-ovo-vegetarian diet do. However, other studies have found that vegetarians can achieve increases in lean body mass comparable to omnivores if 30g/meal of plant-based protein is ingested consistently.
It remains unclear what effect protein supplementation might have on strength and muscle mass among sedentary plant-based eaters. As such, the present study assessed sedentary vegetarian and vegan individuals as to whether increases in dietary plant-based protein could elicit changes in body composition, hand grip and lower body strength independent of exercise. After an 8-week intervention, no significant differences for lean body mass or strength were noted. Results are discussed in the context of trial integrity and supplement consumption issues.

Description
Objective: It’s not well understood how youth perceive existing fruit and vegetable (FV) marketing materials available in schools. This ancillary study sought to assess the acceptability of FV marketing materials freely available to schools among adolescents in grades 6-12.
Methods: Middle and high school adolescents (n=40; 50% female; 52.5% Hispanic) in the Phoenix, AZ area were asked to rank marketing materials (n=35) from favorite to least favorite in four categories: table tents, medium posters, large posters and announcements. Favorites were determined by showing participants two items at a time and having them choose which they preferred; items were displayed to each adolescent in a random order. Adolescents participated in a 20-30 minute interview on their favorite items in each category based on acceptance/attractiveness, comprehension, relevance, motivation and uniqueness of the materials. A content analysis was performed on top rated marketing materials. Top rated marketing materials were determined by the number of times the advertisement was ranked first in its category.
Results: An analysis of the design features of the items indicated that most participants (84%) preferred marketing materials with more than 4 color groups. Participant preference of advertisement length and word count was varied. A total of 5 themes and 20 subthemes emerged when participants discussed their favorite FV advertisements. Themes included: likes (e.g., colors, length, FV shown), dislikes (e.g., length, FV shown), health information (e.g., vitamin shown), comprehension (e.g., doesn’t recognize FV), and social aspects (e.g., peer opinion). Peer opinion often influenced participant opinion on marketing materials. Participants often said peers wouldn’t like the advertisements shown: “…kids my age think that vegetables are not good, and they like food more than vegetables.” Fruits and vegetable pictured as well as the information in the marketing materials also influenced adolescent preference.
Conclusion: Students preferred advertisements with more color and strong visual aspects. Word count had minimal influence on their opinions of the marketing materials, while information mentioned and peer opinion did have a positive effect. Further research needs to be done to determine if there is a link between adolescent preferences on FV marketing materials and FV consumption habits.

Description
The purpose of this cookbook was to provide students that live in the Barrett dorms with easily accessible nutritious meals that prevent total reliance on the dorm's dining hall throughout the year. Limitations of this research included staying within budget, the availability of near-by grocery stores, meal preparation time, and the types of appliances which can be used in dorms. While living in dorms many students may find that dining halls have a large variety of food offerings that are consistently available. Although there are many options, they are not necessarily the healthiest choices. In addition to health these options rarely change. For safety reasons students are limited to dorm room appliance options that include a mini-fridge and a microwave. There is not a lot of cooking you can do with just a microwave, but with the proper knowledge it is surprisingly enough to make a great meal. In addition to appliances students can utilize cutting boards, plates, and plastic utensils, but if students are not educated about cooking diverse meals it is easy to venture toward unhealthy meal choices. Attending college can be costly. Expenses of tuition, books, supplies and living fees can add up quickly. Students are always in need of healthy meal options that are also healthy for their bank accounts. This cookbook contains affordable, healthy, and quick to make recipes. Virtually everyone who has ever been a student usually has a weekly/monthly budgetary amount to spend and cooking their own meals in the dorms will turn out to be much cheaper alternative to having dining hall meals every day. It was interesting to create a week full of meal preps for breakfast, lunch and dinner- including snacks with various alternatives. Not every student has a vehicle in which they can get necessary ingredients for cooking; Therefore, this cookbook has a grocery store map that includes address and store hours to aid students in choosing closer more convenient locations. In college, the journey to a healthy lifestyle is not easy. There are many ways to keep on track and follow the routine which works for both the body and the mind. Following the easy recipes within this cook book will minimize the risk of freshman 15 weight gain and decrease the time spent on both cooking and coming up with healthy meal ideas. These meals are uncomplicated, affordable, and take little to no effort. Barrett CookBook for Dorms main mission was to provide students with a foundation for a nutritional, flexible, and stress-free dining environment without the added stress of constantly thinking about what goes into their bodies.

Description
The concept of this thesis is the importance of dietary fiber and how it can be further integrated into the American diet. The adequate intake (AI) of fiber for men and women is thirty-eight and twenty-five grams respectively. I was inspired to focus my research on increasing fiber intake because the typical American consumes fifteen grams of dietary fiber which is well below the AI. The purpose of this project was to inform individuals on the importance of dietary fiber, but also to create and compile recipes which would make it easy for people to increase their intake of dietary fiber. There are two parts to this project: a literature review and a cookbook. The literature review discusses the health benefits of fiber as to how its properties of viscosity and fermentability allow for weight loss, decrease appetite and energy intake, decrease postprandial insulin and glucose levels, impact gut health, lower blood lipid levels in order to protect against atherosclerosis and coronary heart disease, decrease inflammation, and reduce levels of inflammatory marker C-reactive protein. The cookbook provides the ideas for integrating high fiber foods into one's diet. There are three different categories in the cookbook: snacks, lunch and dinner, and breakfast. The snacks and breakfast provide around five grams of fiber per serving, if not more, whereas the lunch and dinner options provide around fifteen grams in a meal. Not only are these recipes high in fiber, but they are also nutrient dense, meaning they provide more than just the listed health benefits in the literature review. Having these recipes and increasing awareness of the benefits which they contain will help individuals to meet the AI of fiber while still enjoying delicious meals.

Description
Cases of diet-related illnesses are some of the most common illnesses we witness today. From heart disease to type 2 diabetes, from obesity to hypertension, many of these diseases are easily prevented by lifestyle changes. However, it is much easier to instill healthy habits in a population from the start rather than trying to change habits later, even if one's health depends on it. A pastime as simple as cooking allows us to take responsibility for our own health by (quite literally) taking it into our own hands. This is why I chose to write a cookbook for my honor's thesis. More importantly, this is why I chose to write a cookbook geared towards young children. My target audience is 8-11 years old because that's when I first started to cook, and it's a habit that has kept me well to this day. Within this cookbook, readers will find over 30 (mostly) healthy recipes for breakfast, lunch, dinner, snacks, and desserts, complete with written instructions and photographs to aid with meal preparation. My hope is that, during my career, I will be able to publish this book and distribute it to children who might not have an interest in cooking, but can learn basic cooking skills from my book. If kids get working in the kitchen, they might keep cooking as they grow older, which will help them keep control of their health for the better.

Description
College students experience a significant weight gain that is much greater than an age matched population. The rate of gain is 5.5 times greater than the average population, leading to the popularization of the term "Freshman 15". The etiology of weight gain among college students is multifactorial, and it includes stress, time management, GPA pressures, extracurricular activities, financial obligations, transportation challenges, and often a new living situation. Other factors include bring unhealthy habits from their family of origin to their new university, and they are introduced to an environment that is unfamiliar, and they are expected to be independent and make their own decisions about a variety of lifestyle habits. Understanding the factors that influence food literacy, food choices, and lifestyle habits are integral to understanding which stage of change within the Transtheoretical Model an individual is in is ey to developing strategies for combating weight related health issues. The purpose of presenting a food demonstration to a group of freshman dorm dwelling students was to determine what stage of change in the Transtheoretical Model the average college freshman is in. The study found that exposing this group to the food demonstration pushed the students into either the contemplative stage or preparation stage for adopting healthy behavior changes regarding eating habits.

Description
This project looks into elementary school lunches around the world, with a focus on nutrition and government involvement. The project uses recent obesity research to determine the extent of childhood obesity and draws connections between obesity rates and each country's school food policies and resulting school lunch meals. The countries researched are Greece, the United States, Japan, and France. An effort is made to find accurate representations by using real unstaged pictures of the school lunches as well as using real, recent school lunch menus. Analysis of the nutritive balance of each country's overall school lunch meals includes explanation of possible reasoning for lower quality or lesser-balanced school lunch meals. In Greece, the steadily rising child obesity rates are possibly due to Greece's struggling economy and the loss of traditional Greek foods in school lunches. In the U.S., the culprit of uncontrolled obesity rates may be a combination of budget and an unhealthful food culture that can't easily adopt wholesome meals and meal preparation methods. However, there have been recent efforts at improving school lunches through reimbursement to schools who comply with the new USDA NSLP meal pattern, and in combination with a general increased interest in making school lunches better, school lunches in the U.S. have been improving. In Japan, where obesity rates are fairly low, the retaining of traditional cuisine and wholesome foods and cooking methods in combination with a higher meal budget are probable reasons why child obesity rates are under control. In France, the combination of a higher budget with school lunches carefully calculated for balance along with traditional foods cooked by skilled chefs results in possibly the most healthful and palatable school lunches of the countries analyzed. Overall it is concluded that major predictors of more healthy and less obese children are higher food budgets, greater use of traditional foods, and more wholesome foods and cooking methods over packaged foods.

Gluten is another name for natural proteins found in wheat, rye, barley and other grains that are commonly found in most boxed, pre-made, or baked items. However, the number of people diagnosed with Celiac's Disease, Non-Celiac Gluten Sensitivity, or Wheat Allergy has risen dramatically over the past few decades. In fact, the Gluten-Free Market is estimated to be worth 6.6 billion dollars by 2017. Therefore, this cookbook was made to provide quick, easy, and diverse recipes for people unable to ingest gluten without hurting their wallets.

Description
Background: The USDA Fresh Fruit and Vegetable Program (FFVP) provides accessibility, variety, and nutrition education to increase exposure to fresh F/V to school children. The aim of this study examines Arizona FFVP’s nutrition education frequency and delivery in relation to the effects by the COVID-19 pandemic for SY 2019-2020, SY 2020-2021, and SY 2021 - 2022. Methods: A retrospective cross-sectional analysis of 57 Arizona school food managers (FSM) (and alike positions) (N=143; n=57; 18%(10) used Spanish; 82%(47) used English; FFVP site-level FSM = 81%(41); FFVP Non-FSM
= 19% (11); 88% (50) rural; 12%(7) urban) during SY2019 – 2020, SY2020 – 2021, and SY2021 - 2022. Participants were surveyed for their perspective of FFVP service, nutrition education, and partnerships. The statistical analysis used quantitative and qualitative content variables presented as percentages.
Results: Nutrition education were consistently delivered twice a week. FFVP service delivered most commonly 2 days/week (TF1 at 63% (26); TF2 at 59% (20),TF3 at 54% (19); TF 4 at 53% (19)). FFVP nutrition education was most frequently delivered 2days/week (TF1 at 55% (18); TF2 at 55% (18); TF3 at 54% (15); TF4 at 54% (20)). Teachers were most responsible for delivering nutrition education weekly in classrooms TF1 at 55%(21), TF2 at 44%(16), TF3 at 38% (15), TF4 at 45%. Most frequent method to select nutrition education was based on produce served that week (TF1 at 40% (23), TF2 at 36% (21), TF 3 at 39% (21),TF4 at 40% (24)) and day TF1 at 37% (21), TF2 at 36% (21), TF3 at 35% (19), TF4 42% (25).
Conclusion: FSM and alike positions are important to FFVP services. Arizona FFVP schools were able provide consistent nutrition education even through a nationwide school closure caused by COVID-19 pandemic.
