Description
This study examined the effect of consuming pinto, black, and dark red kidney beans with white rice in comparison to a white rice only control meal on the glycemic response of adults with type 2 diabetes (T2D). These bean and rice combinations are part of many traditional diets. Seventeen subjects with T2D treated by diet and/or metformin were randomly assigned to 4 treatments: white rice (control), pinto beans/rice, black beans/rice, and dark red kidney beans/rice. All treatments were portioned by weight and matched for available carbohydrate content of ∼ 50 grams. Capillary whole blood samples were collected at baseline and at 30, 60, 90, 120, 150 and 180 minutes posttreatment and assessed for glucose concentration using the YSI Stat Plus Analyzer. Net change glucose responses were significantly lower for the pinto, black, and dark red kidney bean and rice meals than control at 90, 120 and 150 minutes posttreatment (P < 0.05). Incremental area under the curve (iAUC) values were also significantly reduced for the bean/rice meals containing pinto (P < 0.01) and black beans (P < 0.05) in contrast to the rice control. Results suggest that the combination of whole beans and rice may be beneficial to those with T2D to assist with blood glucose management.

Description
Objective: Vinegar consumption studies have demonstrated possible therapeutic effects in reducing HbA1c and postprandial glycemia. The purpose of the study was to closely examine the effects of a commercial vinegar drink on daily fluctuations in fasting glucose concentrations and postprandial glycemia, and on HbA1c, in individuals at risk for Type 2 Diabetes Mellitus (T2D). Design: Thirteen women and one man (21-62 y; mean, 46.0±3.9 y) participated in this 12-week parallel-arm trial. Participants were recruited from a campus community and were healthy and not diabetic by self-report. Participants were not prescribed oral hypoglycemic medications or insulin; other medications were allowed if use was stable for > 3 months. Subjects were randomized to one of two groups: VIN (8 ounces vinegar drink providing 1.5 g acetic acid) or CON (1 vinegar pill providing 0.04 g acetic acid). Treatments were taken twice daily immediately prior to the lunch and dinner meals. Venous blood samples were drawn at trial weeks 0 and 12 to measure insulin, fasting glucose, and HbA1c. Subjects recorded fasting glucose and 2-h postprandial glycemia concentrations daily using a glucometer. Results: The VIN group showed significant reductions in fasting capillary blood glucose concentrations (p=0.05) that were immediate and sustained throughout the duration of the study. The VIN group had reductions in 2-h postprandial glucose (mean change of −7.6±6.8 mg/dL over the 12-week trial), but this value was not significantly different than that for the CON group (mean change of 3.3±5.3 mg/dL over the 12-week trial, p=0.232). HbA1c did not significantly change (p=0.702), but the reduction in HbA1c in the VIN group, −0.14±0.1%, may have physiological relevance. Conclusions: Significant reductions in HbA1c were not observed after daily consumption of a vinegar drink containing 1.5 g acetic acid in non-diabetic individuals. However, the vinegar drink did significantly reduce fasting capillary blood glucose concentrations in these individuals as compared to a vinegar pill containing 0.04 g acetic acid. These results support a therapeutic effect for vinegar in T2D prevention and progression, specifically in high-risk populations.

Banking on a Diet: https://www.youtube.com/watch?v=Jamp5HYDDqg My documentary is about people with diet-related diseases and restrictions who receive food from a food bank. There has historically been very little research on this clientele, but that is changing. In 2014, the hunger research organization Feeding America asked Americans seeking food assistance if they had a diet-related disease. According to Feeding America's Hunger in America report, the survey found that 58 percent of national households have a member with high blood pressure. In Arizona, that's 54 percent. The survey also found that 33 percent of national households have a member with diabetes. In Arizona, that's 42 percent. Dietary restrictions such as food allergies or religious guidelines, on the other hand, are still not reported. I interviewed several food bank clients who, aside from having a diet-related disease, can't eat certain foods because of an allergy, adverse reaction with their medications, or religious guidelines. No matter the individual case, food banks are beginning to realize there's a growing population of clients who can't get the food they need. Food banks nationally, and in Arizona, are taking steps to accommodate the clients they serve who have diet-related diseases and/or dietary restrictions. My documentary focuses on those food bank clients, as well as what the food banks are doing to accommodate them. The biggest issue is that food banks can only work with the food they receive, or use the money that's donated to them to purchase food. The food banks do their best with what they're given and the clients do the same. According to Association of Arizona Food Banks, two of the food bank leaders in diet-conscious services are Desert Mission, a member of AAFB and the HonorHealth system, and Cultural Cup, an independent food bank separate from AAFB. I focused on these two food banks and their clients for my documentary.

The objective of the following research is to analyze the credibility of Ellyn Satter’s Division of Responsibility feeding model and investigate its effectiveness when executed properly. Implementing this feeding model is proven effective in creating peaceful mealtimes, increasing healthy food relationships between children and food, and raising competent eaters. Being a competent eater helps to bypass larger lifelong struggles that threaten children’s health and safety – struggles like obesity, eating disorders, and chronic weight-related health conditions, making this research paramount in helping the children of the world fight the obesity epidemic that has been threatening their generation for more than a decade. It is an unfortunate fact that Ellyn Satter’s Division of Responsibility lack specifics research trials on its effectiveness. The research below is of significant interest because it highlights the effectiveness of this feeding model while addressing its credibility, achievability, and limitations in conjunction with stressing the need for more research trials to be conducted.

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.

University students currently lack sufficient knowledge and resources needed to support healthy eating patterns and nutrition. Comparison of the number of registered dietitians that are available to all students, along with the number of wellness events that are held at each university within the Pacific-12 conference will help determine which schools are best able to support their students' needs. Data was collected using a Google forms survey sent via email to wellness directors of each of the universities in the Pac-12 conference. Eight out of the twelve schools in the conference responded to the survey. The average number of dietitians available to all students (regardless of athlete status) was found to be 1.43 dietitians. Of the schools that responded, the University of Colorado, Boulder, has the most resources dedicated to student nutrition wellness with three dietitians available for all undergraduate students, free dietitian services, and approximately 150 wellness events each year. The success of available nutrition wellness resources was inconclusive as schools did not provide the information regarding student utilization and attendance. Future university promoted nutrition wellness programs should increase the number of affordable dietitians and total wellness events, as well as promote student health services through social media platforms to improve student nutrition knowledge and usage of resources.

For those families that rely on food banks as their main source of groceries for the week, it is not uncommon for the parents or children to not know how to prepare the ingredients in a way that can provide as much nutritional value as possible. A cookbook with a collection of recipes that specialize in using ingredients commonly found in food banks would be one way to help improve the physical and mental health of families while also teaching children how to cook and prepare nutritious meals at home. I was inspired to create these recipes because I wanted to work with food banks and pantries to help educate their clients about healthy eating and cooking techniques. I wanted to show families that they can cook various meals using many of the same ingredients in different ways. I also wanted to develop recipes that encourage children to cook, become more familiar with different food items, and improve their relationship with food since a significant portion of clients are children, meaning they grow up relying on the ingredients food banks offer. After finding out which recipes and other nutritional aid programs currently exist, I spoke with a few different food banks to learn what types of food are typically distributed from food banks. From there, I drafted a list of recipes, worked with AZ Health Zone to analyze the nutrients for each recipe, and revised the recipes to better meet the nutrition standards of AZ Health Zone. As of now, a handful of food pantries, including the AZ Health Zone, agreed to share my total of 9 recipes (in English and Spanish) with their clients.

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.

ABSTRACT
Many natural interventions have been effective at lowering postprandial glucose concentrations (PPG) in research trials and, theoretically, should have favorable effects on the prevention and management of T2DM. Natural interventions include vinegar, nuts and exercise. Green tea has been demonstrated to also possessing antiglycemic effects. Thus, green tea, and its most abundant catechin EGCG, are being consumed for its potential health benefits in cancer prevention and in its inhibitory effects on α-amylase. Many studies have found EGCG to inhibit α-amylase an enzyme needed in the breakdown of carbohydrates (CHO). Other studies have looked at EGCG and its potential for lowering PPG concentrations due to its inhibitory effects on α-amylase in both mice and humans. Yet there is no research on Matcha tea specifically. Matcha tea is green tea in powder form; hence, it is consumed in its entirety unlike traditional teas which are steeped in bags. The purpose of this study was to determine whether Macha tea impacts PPG concentrations in healthy adults. Twelve subjects completed this randomized controlled, single blinded, crossover study. On three separate occasions the twelve subjects consumed a bagel and jam with either water, Lipton green tea, or Macha tea. Fasting blood glucose was taken upon their arrival. Once the tea or water and bagel with jam were consumed PPG concentrations were measured every 30 minutes until 120 minutes were reached. Results showed no statistically significant effects on PPG concentrations in either test groups (p=.960). However, this study did not measure EGCG levels in the tea provided. Therefore, further research should be done with known EGCG amounts to see its effects on PPG concentrations to fully rule out its potential.
