Could that glass of red wine negate the effects of your workout? A new study suggests that it might be.
Red wine, touted for its antioxidant powers from resveratrol, is thought to have a positive effect on cardiac health. A study published in the Journal of Physiology followed 27 men over the age of 65. All followed an intense workout regimen, but half of the men were given a resveratrol supplement, while the others received a placebo. The placebo recipients were found to have lower body fat, lower blood pressure and lower cholesterol than the resveratrol users. This contradicts the findings in previous studies, which linked the antioxidant to improved heart health.
“We were surprised to find that resveratrol supplementation in aged men blunts the positive effects of exercise training on cardiovascular health parameters, in part because our results contradict findings in animal studies,” said Dr. Ylva Hellsten, the leader of the project, in a statement.
The caveat to the study is that the dose of resveratrol was 100 times higher than what is found in a glass of red wine.
So until further notice, keep working out hard, and enjoy your wine in moderation.
