There's nothing wrong with a glass a day.
A glass of wine a day keeps the doctor away — or does it? From the French to the Sardinians, cultures in which people tend to drink wine daily have famously low rates of heart disease and lead longer lives , on average, than Americans do. But does drinking wine actually help you live longer?
For starters, much of the research on red wine and mortality don't focus on wine itself. Rather, the research investigates the health effects of polyphenols, a type of antioxidant in wine. These chemicals shield cells from damage caused by unstable molecules called free radicals, which are associated with heart disease and cancer risk, and have been proposed as one potential reason for wine's purportedly positive health effects.
There is some evidence that drinking moderate amounts of wine is heart-healthy, Baranchuk said.
Is a glass of wine a day bad for you?The problem is that heart disease isn't the only factor in health and longevity. And the alcohol in wine may negate any benefit from polyphenols."Unfortunately, there isn't much evidence that alcohol provides a protective effect," Klein said."There's much more evidence that it's a risk factor.
