the risks and benefits of red wine and alcohol and the heart

Is Red Wine Good for You?

Myth: Drink lots of red wine – it’s good for heart health.

Fact: Many studies have reported the benefits of limited wine intake for heart health.

My Recommendation: Know what the good limits are to avoid the risks associated with alcohol intake.

In 2011, the American Heart Association polled a thousand adults about red wine health benefits and found that 76 percent thought that wine could be good for the heart but only 30 percent knew what the recommended limits were.

Well, if you’re drinking wine for health’s sake, you better know the limits.

The French Diet

Scientific research shows that wine contains all sorts of healthy compounds and because of that I have seen many patients go overboard.

You may recall that wine is at the heart of the so-called French paradox. French society, despite all the rich, fatty foods consumed, have a relatively low level of heart disease despite an average cholesterol of 250, which a lot of doctors would find troubling. The celebrated reason for this paradox is the high wine consumption.

I’ve had patients tell me they were following the French example and drinking red wine for health: two or three glasses, or even a bottle of wine a day. Maybe that was their rationale for drinking, but I always pointed out that the French also had the highest incidence of cirrhosis in the world.

Resveratrol & Benefits of Red Wine

Red wine, and grape juice, for that matter, come from the red grape, which definitely has some good things going for it. It contains natural antioxidant compounds – including flavonoids and resveratrol – that have been linked in scientific studies to heart-healthy properties. Resveratrol itself has been the subject of more than fifteen hundred experiments since the 1980s, and the research appears quite promising. Among the most important findings:

  • Protects against common free radical damage to the sensitive endothelial lining of arteries in atherosclerosis.
  • Improves mitochondrial function (cellular energy production) and aerobic capacity in mice.  Researchers have stated, “resveratrol shifts the physiology of middle-aged mice on a high-calorie diet towards that of mice on a standard diet and significantly increases their survival.”
  • Protects against fragile, leaky blood vessels involved in age-related macular degeneration and diabetic retinopathy, major causes of vision loss.

Alcohol or some compounds in alcoholic beverages, such as resveratrol, may help counteract blood clotting and reduce heart attack or stroke risk. However, more research is needed to learn the specifics.

As far as which alcoholic beverage might be most “medicinal,” wine may be the winner. According to one Finish study of 2,500 men with similar socioeconomic status over a 29 year period concluded, wine drinkers had a 34 percent lower mortality rate and better quality of life than beer or spirit drinkers.

Red Wine Benefits vs. Moderation

If resveratrol is on your mind, you can surely find it in wine, but in modest amounts. You can also find antioxidant compounds in fruits and vegetables, and in nutritional supplements.

Moderation is the name of the game when it comes to alcohol.

I’ve been asked countless times, “Is one drink or a glass of red wine a day okay?” My usual recommendation to patients was to cool it with alcohol and for those who like to drink, I’m okay with a glass of wine four to six times a week. Don’t increase, and that goes for any kind of alcohol. Alcohol’s effects on the heart can go either way, and again, if you drink alcohol, I’d go with wine. The incidence of cardiovascular disease in those who drink these moderate amounts is actually lower than in nondrinkers. But increased intake eliminates any possible benefits and raises the risk for problems. Drinking more than one or two drinks a day increases the risk of high blood pressure, heart failure, obesity, diabetes, stroke, and damage to the liver. The risk of breast cancer, suicide, and accidents also goes up.

My recommendations are in line with the American Heart Association, which emphasizes moderation for any kind of alcohol, whether wine, beer, or spirits. According to the AHA, limit consumption to no more than 2 drinks per day for men and 1 drink per day for women. That comes out to about 8 ounces of wine for men and 4 ounces of wine for women.
