How many glasses of wine does it take to see health benefits?

Try hundreds.

A new study published in the journal JAMA Internal Medicine found that the antioxidant resveratrol does not improve longevity when consumed at levels naturally occurring in foods like grapes, red wine and dark chocolate.

Researchers tracked nearly 800 men and women, 65 or older, analyzing who survived and who died over a nine-year period in relation to their resveratrol levels.

The results showed no benefits in terms of longevity, heart disease or cancer to having higher levels of resveratrol versus lower or moderate levels.

In the study, the resveratrol came only from things like red wine, chocolate, and berries which provides almost negligible amounts of resveratrol compared to the levels found in supplements or the amount used in previous studies with mice.

A person would have to drink hundreds of glasses of red wine a day to match the amounts used in previous resveratrol studies.
