Effect of Acute Nitrate Supplementation on Vascular Function in Hispanic, Black, and White Adults

What this Trial Is About

This research aims to understand racial differences in cardiovascular health by studying vascular function in healthy African American, Hispanic, and Caucasian adults. It focuses on how beetroot juice, a high nitrate supplement, may affect vascular function, particularly in populations at higher risk of type 2 diabetes and cardiovascular diseases due to vascular dysfunction caused by reduced nitric oxide availability. The study is randomized and placebo-controlled to ensure reliable results across these racial groups. Participants will receive either beetroot juice or a placebo drink in two separate visits, spaced at least one week apart to allow for a washout period. Vascular function will be assessed before and 90 minutes after consumption of each supplement. This design helps compare the acute effects of nitrate supplementation on blood flow and vascular responses among the different groups. Throughout the study, forearm blood flow will be measured as the primary outcome over an average of two years. Participants will undergo vascular assessments during each visit, and the researchers will monitor changes to better understand how beetroot juice impacts vascular health. This involves careful tracking of vascular responses to evaluate potential benefits and racial differences in these effects.
