Dried Cabernet Grapes and Cardiovascular Risk Markers

Completed · Not applicable

Conditions studied: Healthy, Postmenopausal Women

In brief

This study assesses the acute effects of dried Cabernet grape intake on vascular function and platelet reactivity in postmenopausal women. Previous studies from this lab and others have demonstrated acute effects on vascular function and platelet reactivity from phenolic-rich food sources. Postmenopausal women are suggested as the study group, as they are likely to have compromised vascular function due to the loss of protective estrogen, and have been the study group for past and present research projects in this lab.
