If you’ve looked to health claims describing the benefits resveratrol, a compound found in chocolate and red wine, to justify your indulgences, you may need to rethink the role of these treats in your health plan. Recent research suggests that resveratrol may not be the ticket to youth and vitality we once thought.
Beyond the mood-boosting benefits of a pleasurable treat, researchers and healthcare experts have long wondered whether there’s something in the composition of chocolate and red wine that improves our health. One widely accepted explanation has been resveratrol, a compound found in both that’s been associated with improved health and longevity.
Resveratrol is a plant compound that occurs in red grape skin and cacao plants, as well as in berries and peanuts. Specifically, it’s a polyphenol, a compound credited with antioxidant properties. Antioxidants are thought to help protect the body against cellular damage and thus reduce risk of conditions such as heart disease and cancer.
Plenty of us have been eager to accept the health claims surrounding resveratrol in red wine and chocolate, welcoming evidence that something we already enjoy might be doing our health some real good. But a 2014 study is trying to rain on our decadent parade, suggesting that resveratrol is likely doing nothing to measurably improve our health.
Three Misconceptions About Stem Cell Therapy From an Insider
What are the misconceptions regarding stem cell therapy?
Research results released in the spring of 2014 indicated—to the disappointment of chocolate and red wine lovers—that resveratrol might not help us live longer. In a study of older individuals living in Italy’s Chianti region, researchers found that the compound was unlikely associated with longer life. They measured resveratrol in the urine of participants and compared levels among those who died over the nine-year course of the study (it was expected that a portion would die, as participants were 65 years of age and older) and those who survived. Resveratrol levels were similar among those who died and those who survived, suggesting that the compound has no significant impact on longevity, at least not in the amounts we consume in food and drink.
Though you may feel a little less justified in treating yourself to a regular glass of red wine or square of dark chocolate, studies related to the health benefits of both—from the impact on bone and heart health to healthy weight—are ongoing. Until we know more, a small indulgence in something that brings you pleasure can likely do more help than harm.
