Deciphering the Effect of Moderate Wine Consumption on Healthy Aging Through Postprandial Extracellular Vesicles
This study aims to investigate how moderate wine consumption influences circulating extracellular vesicles (EVs) in healthy adults. EVs are small particles released by cells that carry proteins, lipids, and genetic material, and play important roles in communication between cells. Participants will consume a single serving of red or white wine, and blood samples will be collected before and after consumption to study changes in the composition and function of EVs. The study will also assess how these EVs affect vascular, immune, and brain-related cells. The results are expected to improve our understanding of how moderate wine intake contributes to cardiovascular and brain health.
