Many of us have heard that red wine—packed with antioxidants—might actually protect against cancer. But a new buzz-killing study says otherwise: your merlot is no healthier than your moscato.

So why doesn’t red wine protect against cancer? Likely because the amount of resveratrol in a glass of wine is too small.

For years, red wine has been touted as a healthier choice than white, mostly because it’s rich in resveratrol — a powerful antioxidant that can reduce inflammation and lower your risk of heart disease and cancer.
