Description
Anxiety is one of the most common mental illnesses in the United States. In this project, I chose to explore how food is one of the most accessible and inexpensive ways of treating anxiety. This creative project examines the major key components of gut health including the balance of neurotransmitters and bacteria in the gut, restoring hydrochloric acid through celery juice, removing heavy metal toxins through food, eating fermented foods, and limiting refined carbohydrates, and high-sugar consumption. Additionally, this creative project explores my own personal journey through the implementation of foods that influence anxiety revealed in a systemic review over the course of a 6-week period.

Description
Chronic diseases place a financial burden on the United States and claim the lives of nearly 2 million Americans every year. Among the chronic diseases that plague American people, type 2 diabetes is particularly prevalent and injurious. Thus, action is warranted to improve prevention and management of this disease. Nutrition plays a significant role in prevention and management of type 2 diabetes and other chronic diseases. Registered dietitians, as nutrition experts, are qualified to use medical nutrition therapy as a method of prevention and treatment for chronic diseases using a nutritional approach. However, there is no consensus as to which eating pattern is the most efficacious. The aim of this review of research was to examine how plant-based eating patterns impact chronic disease conditions, with an emphasis on type 2 diabetes mellitus, as compared to omnivorous eating patterns. A literature search was conducted through the ASU Library, PubMed, and CINAHL using terms related to plant-based diets and chronic diseases, such as type 2 diabetes. The results revealed that a plant-based eating pattern may be beneficial in the prevention and treatment of certain chronic diseases, such as type 2 diabetes. Specifically, adults who have type 2 diabetes and consume a plant-based diet may exhibit enhanced glycemic control as evidenced by less insulin resistance, increased incretin and insulin secretion, greater insulin sensitivity, and improved HbA1c levels. There is sufficient evidence for registered dietitians to recommend a plant-based approach to patients with type 2 diabetes who would like to achieve enhanced glycemic control.

Description
Immigrants and their U.S.-born children account for 26% of the American population as of 2020. Despite this large proportion, 14% of immigrants live below the federal poverty line compared to 12% of U.S.-born citizens. The immigrant population is vulnerable to food and housing insecurity and limited access to social services and medical care, on top of navigating the increasingly convoluted immigration system. Migrant women and children are especially at risk for systemic, poverty-related adversities. Periods of pregnancy and postpartum are particularly financially straining due to employment disruptions and additional expenses. Migrant mothers experience adverse health outcomes due to chronic stress, unstable living situations, integration barriers, and an unfavorable occupational environment during pregnancy. In addition to the postpartum needs of a new mother and her baby, these challenges may be barriers to maintaining breastfeeding. The unanticipated COVID-19 pandemic exasperated many existing systemic inequities and brought additional hardship. This study aims to investigate breastfeeding rates among immigrant mothers compared to U.S.-born mothers and other social disparities that affect health. While this study did not find a statistical difference between breastfeeding adherence and immigrant status during the COVID-19 pandemic, other risk factors relating to maternal-child health were identified. Immigrant families were more likely to experience job or income loss and a higher frequency of food insecurity compared to families with U.S.-born parents. The risks of being impoverished greatly reduce the incidence of breastfeeding, which can offer tremendous health benefits both to mother and baby. Most immigrants migrating to the U.S. are ethnic minorities who face additional societal disparities in culture, employment, economic stability, safety, and healthcare. The burden of social determinants of health that impact this population is not unique to adults. The moment a child is born into an immigrant family, particularly if they are also an ethnic minority, they inherit risk factors that can impact their entire lifespan. Ultimately, the risks associated with pregnancy and infant feeding are issues of social justice and health equity.

Description
Optimizing the microbiome to improve gut health has become a prominent research topic that aids in relieving stomach issues through nutrition and the introduction of beneficial bacteria. By incorporating a few gut-healthy foods into the diets of developing children, I hope to decrease their chances of developing pediatric diseases and experiencing stomach problems as they grow older. The purpose of this cookbook is to use ingredients that are beneficial to the gut microbiome and incorporate them into healthy recipes that children can easily understand and create themselves. Additionally, many factors influence the fluctuation of the gut microbiome, one of which is nutrition, so it is important to maintain a diet rich in foods beneficial to the gut microbiome because it can prevent the onset of certain pediatric diseases. By including gut-healthy recipes in a cookbook targeted towards kids, they can gain independence, engage in a bonding activity with their parents, and be guided into creating and consuming things that are good for their gut and will benefit their health in the future. There are also many benefits for children who use this cookbook, such as developing healthy habits and preventing common disorders like obesity, IBS, and IBD. However, the overarching goal is to create a fun and engaging way for kids to prioritize good gut health for a healthy future. I hope that through this cookbook, kids can take control of their diet and engage in an activity that I enjoyed as a child.

Description
Background: Research has found that nearly a quarter of the American population follows a gluten-free diet in some capacity, while only about 1% of the population is diagnosed with celiac disease. Although the amount of research-based evidence supporting any health benefits of a gluten-free diet in an individual without a gluten- related disorder is limited, the number of people claiming to follow a gluten-free diet continues to rise. Also, despite an increasing belief that gluten is harmful for health, the potentially undesirable effects of gluten substitutions used in gluten-free foods are largely unknown. Due to the protein network encapsulating starch granules, gluten is thought to lengthen the amount of time needed during starch digestion, thereby reducing postprandial glycemia. Therefore, it is predicted that breads containing gluten will produce a lower glycemic response compared to gluten-free breads. Aim: The aim of this study was to investigate the glycemic response of gluten-free bread made with different types of flour compared to bread made with gluten-containing wheat flour. Methods: This study involved a 3-week, randomized, single blind crossover study in which 17 healthy individuals were asked to consume a different type of bread each week, 2 of which were gluten-free. Blood glucose was taken by finger prick at fasting as a baseline measurement, then for 2 hours after bread consumption in 30-minute increments. Results: Across the three groups, there was no significant difference in iAUC values after 120 minutes (p=0.192 ). The greatest mean was seen in the gluten-containing bread (145.3 ± 82.6), then the gluten-free bread made with rice flour (125.5 ± 62.8), and lastly the gluten-free bread made with potato and fava bean flour (112.4 ± 64.5). Conclusion: The inconsistent results of this study compared to previous, similar studies suggests that the postprandial glycemic response of gluten-free products can not be generalized as a whole, but instead is dependent on the type of product and the ingredients used to replace the gluten. Although the results did not show a significant difference, it does argue against the belief that gluten-free products are invariably better for health in the general, non-gluten sensitive population.

Description
There is a considerable amount of research stating that vegetarian diets have an alkalizing effect while the typical western diet is acid-forming. There is substantial evidence regarding the health benefits of an alkaline diet. Although vegetarian diets demonstrate the ability to foster these health benefits, many people are still not willing to adopt a completely vegetarian diet. PURPOSE: To evaluate the effect of following a vegan diet two or three days per week on acid-base balance in a healthy college student population aged 18-30. METHODS: In a one-week interventional design, 23 people were randomly assigned to follow a vegan diet 2 days per week (VEG2;n=7), 3 days per week(VEG3;n=8), or 7 days per week (VEG7;n=8). Urine pH and dietary PRAL were assessed in each group at baseline and after the one-week intervention. RESULTS: There was no significant difference in urinary pH between the three groups (p=0.12). The change in PRAL values after the dietary intervention was different between the 3 groups (p=0.03). CONCLUSION: Adherence to a vegan diet 2 or 3 days per week did not show a significant change in urinary pH or PRAL.

Description
Grains are a major dietary staple in many cultures and countries. Corn can be consumed as either a fruit, vegetable, or grain. In the case of the Corn and Heart Health Study (CHS), the effect of corn flour was examined. The study used three varieties of corn flour (whole grain, refined, and a refined plus bran blend), provided by the North American Millers Association (NAMA), to examine the effectiveness of corn flour on lowering low-density lipoprotein (LDL) cholesterol as well as its effects on the diversity of the gut microbiome. The objective of this analysis was to determine the magnitude of change between pre- and post- intervention serum blood samples and the changes in alpha (within-sample) diversity in the gut microbiome. The study utilized a randomized-single blinded, crossover model. The study was 16 weeks long, with three 4-week long treatment periods with two-week washout periods in between. During each treatment period blood samples, stool samples, a diet record, and questionnaires were collected from participants. Two blood samples were collected at the beginning and end of each treatment period to account for potential day to day changes on LDL cholesterol. For the purpose of this study, the results of blood and fecal analysis were used to determine the effectiveness of the intervention. Fecal analysis using the Shannon Index showed that there was no significant difference in the within-sample microbiome diversity by corn flour type (H=2.86, p=0.72). Pre-treatment plasma LDL levels were subtracted from post-treatment levels and analyzed using a general linear model that controlled for sequence, period and a nested (ID[sequence]) variable to account for the within-person crossover design. This showed that the bran-enriched flour had the highest mean reduction in LDL cholesterol while the refined and whole grain flour resulted in increases in LDL cholesterol. The change in LDL cholesterol for bran-enriched flour was significantly different from the refined flour (Mean Difference of -14.97 mg/dL; P=.041). The results of this study indicate that refined corn flour enriched with bran could be a recommended addition to the diet to prevent cardiovascular disease and reduce LDL cholesterol in individuals who are at low risk.
