Official title
Pilot Study: The Effects of Whole Grapes on Markers of Health
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The investigators hope to learn about the effects of whole grapes, in the form of freeze-dried grape powder, on markers of health. Phytochemical rich food consumption is associated with protection against chronic diseases such as cardiovascular disease (CVD) demonstrating the ability to modify endothelial function and lipemia, but exact causal mechanisms are still not well understood. The investigators will examine metabolic and mechanistic effects of consumption of whole grape powder in chronic as well as acute settings in response to meal challenges by testing blood samples to determine if markers of health have improved. The central hypothesis of this project is that consumption of grapes in the form of a polyphenol-rich freeze-dried whole grape powder (WGP) will attenuate chronic and meal induced oxidative stress and inflammatory responses in obese individuals.
