I am a freshman majoring in Exercise Physiology at Florida State University with the goal of working in the health field. As a pre-health student, I am inspired to be an understanding and caring professional to my patients. Additionally, I am interested in understanding the nutrition and functional food compartment of human science through hands-on work and the application of textbook knowledge.

According to the Centers for Disease Control and Prevention (2016), at least 100 million adults in the United States are diagnosed as pre-diabetic or Type 2 diabetic. With the number of cases steadily increasing in this population, healthcare costs have subsequently increased for both the patient and the health care system. To date, there are few studies (limited to animal models and obese Type 2 diabetic humans) that have examined the health efficacy of mangoes. Therefore, the purpose of the current study is to examine the effect of fresh mango on glycemic indices, body composition, and vascular health measures. Upon favorable outcomes and with more definite evidence from human studies, mangoes can potentially be implemented in America’s diet to help mitigate the advancement and diagnoses of pre and Type 2 diabetes and, as a result, aid in a reduction of healthcare costs. The current study is a 24- week, randomized, controlled experiment including 40 overweight or obese, pre-diabetic men and post-menopausal women aged 50 to 70 years with no diagnosed chronic diseases. Participants will be randomly assigned to one of two groups: 1) one fresh Tommy Atkins mango (120 g) or 2) an isocaloric granola bar. Visits will include various examinations and measurements to analyze biomarkers related to glycemic control and lipid profiles, vascular measures, and body composition. We hypothesize that daily consumption of one mango per day for 24 weeks will improve the indices of glycemic control, cardiovascular health, and body composition in overweight and obese individuals with prediabetes.
