The Potential for Pomegranate Juice to Ameliorate Endothelial Dysfunction

Completed · Not applicable

Conditions studied: Healthy

In brief

This study will be a randomized, double-blind, crossover intervention to investigate the health effects of acute ingestion of pomegranate juice when consumed with a high fat meal. After one week of controlled dietary intervention, subjects will consume a high fat morning meal supplemented with either pomegranate juice or a juice-free sweetened beverage. After consumption of the breakfast meal, subjects will be assessed for endothelial function and postprandial meal response.
