The purpose of the study is to assess vascular function in African Americans, Hispanic and Caucasian Americans to better understand racial differences in cardiovascular health. The investigators will further investigate the affect of Beetroot juice on the vascular function of all participants.
African Americans and Hispanic individuals have the highest incidence of type 2 diabetes, which increases their risk of all cardiovascular diseases. One of the hallmarks of type 2 diabetes is vascular dysfunction, caused by a lack of nitric oxide bioavailability. Vascular function and blood flow responses to exercise have been shown to improve after nitrate supplementation (beetroot juice), However, whether nitrate supplementation will improve vascular function in African American and Hispanic individuals remains unknown. The investigators will perform a randomized, placebo-controlled study in…
