Description
According to the CDC, diabetes is the 7th leading cause of death in the U.S. and rates are continuing to rise nationally and internationally. Chronically elevated blood glucose levels can lead to type 2 diabetes and other complications. Medications can be used to treat diabetes, but often have side effects. Lifestyle and diet modifications can be just as effective as medications in helping to improve glycemic control, and prevent diabetes or improve the condition in those who have it. Studies have demonstrated that consuming vinegar with carbohydrates can positively impact postprandial glycemia in diabetic and healthy individuals. Continuous vinegar intake with meals may even reduce fasting blood glucose levels. Since vinegar is a primary ingredient in mustard, the purpose of this study was to determine if mustard consumption with a carbohydrate-rich meal (bagel and fruit juice) had an effect on the postprandial blood glucose levels of subjects. The results showed that mustard improved glycemia by 17% when subjects consumed the meal with mustard as opposed to the control. A wide variety of vinegars exists. The defining ingredient in all vinegars is acetic acid, behind the improvement in glycemic response observed with vinegar ingestion. Vinegar-containing foods range from mustard, to vinaigrette dressings, to pickled foods. The benefits of vinegar ingestion with carbohydrates are dose-dependent, meaning that adding even small amounts to meals can help. Making a conscious effort to incorporate these foods into meals, in addition to an overall healthy lifestyle, could provide an additional tool for diabetics and nondiabetics alike to consume carbohydrates in a healthier manner.

Description
This research investigates the whether dietary and nutritional treatments will improve some of the symptoms of autism. This treatment includes a combination of 6 nutritional and dietary treatments, which are vitamins/minerals, essential fatty acids, Epsom salts, carnitine, digestive enzymes, and healthy gluten-free, casein-free diet. 55 participants were involved in this study; 28 participants are in the Treatment Group and 27 participants in the Delayed Group. Data from the PDD-BI form, the ADOS form, the CARS form and the professional SAS form will be used in this thesis project for analyses. Factors analyzed are age, gender and severity [initial professional SAS data] and then correlating these factors with data from PDD-BI (autism composite score and each subscale), ADOS and CARS. The data analyses show that changing the dietary and nutritional needs of children/adults with autism improves the symptoms of autism (as rated by the PDD-BI) by approximately 22% in the treatment group vs. 3% in the non-treatment group, p<0.001. Overall, these results also suggest that the treatment is equally beneficial for males and females of varying age (young children to adult) and of all severity levels.

Description
The aim of this paper is to investigate a few of the primary pillars of the Paleo diet for evidence to either support or refute their efficacy and safety such that a more educated decision can be made by lay-persons who are wishing to make improvements in their overall health via dieting. To accomplish this goal a basic overview of The Paleo Diet (also known to some as the Paleolithic Nutrition Movement) is given based on the writings of Dr. Loren Cordain in his book The Paleo Diet. Next, analyses of a few of the basic characteristics of the diet are presented based on an in-depth literature review that was performed using PubMed (Medline), Cochrane and Google Scholar databases until March of 2015. The findings of this investigation raise concerns with respect to the safety of some of the main principles of the diet such as its high protein, low carbohydrate content that is relies heavily on the consumption of red meat. The current literature on what the diet of the people of the Paleolithic era may have consisted of is also presented in order to shed light on the origins of the diet and see how closely the diet prescribed The Paleo Diet meshes with the most current data on the topic.

Description
Early humans adapted to eating cooked food with increased energy density and absorption of macronutrients. However, in modern times many suffer from diseases like obesity and type 2 diabetes which can result from too much energy being absorbed from food. This study measures glucose responses to a high glycemic meal with a side dish of raw or cooked vegetables. There was a slight trend for raw vegetables to have decreased postprandial blood glucose responses when compared to cooked vegetables.

Description
This paper begins by exploring the prior research that has shown how eating a plant-based diet can affect the human body. Some of these effects include: improved mood, energy levels, gut health, alkalized urine pH, as well as, lowering the risk of hormonal imbalance, kidney stones, diabetes, cancer, and coronary artery disease. The worries that generally accompany eating a fully vegan diet, which include, malnutrition and protein deficiency, are also addressed in the background research. In attempt to build upon previous research, a weeklong experiment was conducted testing 3 different factors, which include: gut health, improved mood, and urine pH. Mood states were measured quantifiably using a POMS (profile of mood states) test. Gut health was measured using several factors, including consistency and frequency of bowel movements, as well as, GI discomfort. Two 24-hour urine samples were collected from each of the subjects to compare the pH of their urine before and after the study. The sample size of this study included 15 healthy, non-smoking, subjects, between 18-30 years of age. The subjects were split up into 3 stratified random samples, including, an omnivore control group, vegan control group, and experimental vegan group. The experimental vegans had eaten meat/eggs/dairy regularly for their whole lives before the start of the study, and had consented to eating a vegan diet for the entirety of one week. While the data from the control groups remained mostly constant as predicted, the results from the experimental group were shown to have a significantly better mood (P<0.05) after one week, as well as, a significantly higher urine pH (P < 0.025) than they did before the study. However, the experimental group did not show a significant change in stool frequency, consistency, or GI discomfort within one week. The vegan control group, which included subjects who had eaten a plant-based diet for 1-3 years, had much better gut health scores. This leads us to believe that the vegan gut microbiome takes much longer to transform into than just one week unlike urine pH and mood, which can take as little as one week. These findings warrant further investigation.

Description
Resistant starch is defined as a portion of starch that bypasses breakdown and absorption in the small intestine. Several studies have shown a relationship between resistant starch consumption and decreased postprandial blood glucose. RS3 in particular, is formed when a starch containing food changes its chemical structure after it is cooked and then cooled. This characteristic enables a food to lower its glycemic index after it has been cooled enough to promote retrogradation and can potentially be used as a dietary intervention to control blood glucose in diabetics and individuals with insulin resistance. Although many studies have been done on rice and potatoes, pasta has not been tested as extensively. This investigation examines the effect of RS3 in pasta on postprandial glycemic response in 13 healthy participants. After consuming 2 bagels the night prior and coming in to the lab in a fasted state, the test subjects were given a warm or cold pasta dish to consume. Blood glucose samples were taken at fasting, 30 minutes, 60 minutes, 90 minutes, and 120 minutes for both the hot and cold dish. Analysis of the results indicated that there was an average of a 4.1 mg/dl decrease in blood glucose at 30 min and a 2.4 mg/dl decrease at 60 min for the cold pasta. This was followed by a 3.9 mg/dl increase at 90 min and 3.3 mg/dl increase at 120 min. Although these results show a small difference in postprandial glucose response, statistical analysis did not deem it significant difference.

Description
One of the great difficulties in leading America to become a healthier nation involves overcoming the socioeconomic disparity that exists between income and health literacy. Impoverished communities consistently lack the proper health education to make quality food purchases and healthy lifestyle choices, leading to higher rates of obesity. Through FitPHX Energy Zones, an after-school program designed to encourage Phoenix youths to lead healthier lifestyles through an innovative use of library spaces, I provided health education and opportunities for physical activity for 8 to 14-year-olds in underserved Phoenix communities. However, although this intervention made significant progress with the kids' health literacy development over the course of the program, it is difficult for community-based intervention programs to continue in the long run due to budget or other extraneous circumstances. Once the program ends, there needed to be a way to continue to reach the kids beyond the scope of the program such that they can continue to experience the lessons taught during the program. Following the conclusion of FitPHX, I created an interactive book for the kids I worked with to help them retain the health and nutrition knowledge taught during the program.

Description
Nutritional support offered before and during chemotherapy treatment is proven to improve the outcomes of treatment (Bernhardson, 2016). This project seeks to examine current forms of nutritional support offered to patients, as well as the models of care and support teams in cancer treatment centers. The basis for this project incorporated personal experiences at M.D. Anderson Cancer Center in Gilbert, Arizona as well as research into the work of clinical oncology dietitians. An intense interest in food videos and blogs also informed this project, and was incorporated in the hope of providing chemotherapy patients a platform to discover recipes specific to their unique situation. The combination of this research was utilized to create several videos which demonstrated specific recipes beneficial for patients as well as creating a platform for this particular population. While nutritional support can take multiple forms, the focus of nutritional support surrounds symptom management. The common side effects of chemotherapy such as nausea, mucositis (mouth sores), and extreme weight loss were taken into account. Recipes were formulated to directly address these conditions and each recipe was broken down into the benefits of both macronutrients and micronutrients. In addition to formulating specific recipes and videos, barriers to proper nutritional support were examined and explained. These barriers include understaffing of clinical dietitians at cancer treatment centers, a patient's lack of transportation to and from treatments, as well as an overwhelming viewpoint that nutritional support is only required for extreme cases of malnutrition. Combatting these barriers and offering more forms of nutritional support will help to increase a patient's positive response to treatment, manage their symptoms, and improve their overall quality of life.

Description
The purpose of this project is to understand how wearable technology can improve a person's practice of self-tracking, or monitoring one's data. Self-tracking is regularly recording information about one's different life patterns (such as diet, activities, or sleep). Some technology that helps users record personal data are seen today as devices (FitBit, Smart Watches) or as applications (MyFitnessPal). Data is collected for the user to observe certain habits that he/she would like to improve upon. Their personal data that is collected and this helps keep the person self-tracking. This data can be converted to show personal behavioral patterns which a person analyzes so that they can make changes that lead to a healthier lifestyle. People self-track in order to analyze their behavior patterns, so that they can make changes to those patterns that lead to a healthier lifestyle. However, some people are not motivated to continue self-tracking, or use their data to make positive behavioral changes. To better understand this problem, we are conducting four co-design sessions with four users who have shown varying levels of self-tracking. Sessions' activities included: storyboarding, reviewing existing user interfaces, generating feedback on prototypes and discussion into thoughts and feelings about the prototype and self-tracking in general. Current findings highlight the importance of customization and simplicity within the application. We are developing an Apple Watch prototype application for self-tracking that incorporates features tailored to those needs in order to better motivate users to track and improve their well-being. Our main goal is to gain a better understanding of our participants and their need and usage with self-tracking. More information can be found on our website at ani6gup.me/CareTrack.

Description
Most reliable nutrition information can be found online, but it can be nearly impossible to differentiate from the unreliable blogs and websites that claim their information is correct. Because of this, it can be difficult for students to determine which information is true and which advice they will follow. During this time of growth and learning, it is essential that students have access to accurate information that will help them to be healthier individuals for years to come. The goal of this project was to provide students with an easily accessible and reliable resource for nutrition information that was presented in a simple and relatable way. The following videos and attached materials were created in response to ASU student needs and will be available for students on the ASU wellness website.
