Ever heard the old adage that a glass of red wine brings extended youth? This may not be true, according to a new study relaesed Monday. A new nine-year study in Tuscany, Italy has shown that resveratrol, an ingredient in red wine previously thought to have health benefits, failed to promote longevity among Italians who ate a diet rich in the antioxidant.
A study of 783 men and women ages 65 and older found that they didn’t live longer and were just as susceptible to heart disease and cancer as those who consumed less resveratrol. The study, led by Richard Semba, an ophthalmologist from John Hopkins School of Medicine, followed the participants, pooled from two villages in Tuscany for the span of nine years.
Pervious laboratory studies have suggest that resveratrol, also found in grapes, peanuts, and chocolate, may have unique benefits that could help slow the aging process and keep cells healthy. However, a lack of evidence that it helps humans has prevented recommendations for the antioxidant’s use in preventing disease. In 20120, GlaxoSmithKline dropped development of a drug designed to mimic resveratrol because it failed to help cancer patients per Bloomberg News.
This study suggests that dietary resveratrol from Western diets in community-dwelling older adults does not have a substantial influence on inflammation, cardiovascular disease, cancer, or longevity,” the researchers wrote in the paper published Monday in the journal JAMA Internal Medicine.
In the study, researchers used urine metabolite levels to measure resveratrol consumption in the pool of Italians. Semba said the findings suggest something else may be at work besides resveratrol. Previous studies have shown a link between red wine and chocolate and lower inflammation which can actually hurt the heart.
“The thinking was that certain foods are good for you because they contain resveratrol,” Semba said in a statement. “We didn’t find that at all.”
