Can Red Wine Really Prevent Heart Disease?

Have you ever heard that “a glass of red wine a day keeps heart disease at bay?” Some studies on cardiovascular disease have found that while many Frenchmen are intaking a lot of fat, they generally are at lower risk of cardiovascular disease. According to this finding, researchers come up with different assumptions, of which the most widespread one is “the French habit of drinking red wine is the reason of a smaller prevalence of cardiovascular disease in France.” Is wine really good for the heart? Is it better than white wine and beer? Will it bring any harm?

Some studies have shown that moderate drinking is good for health. These studies suggest that red wine has the following benefits:

  1. Increasing the level of good cholesterol.
  2. Blocking the formation of blood clots.
  3. Preventing bad cholesterol from damaging blood vessels.
  4. Normalizing your blood pressure.

However, does red wine really do good for the heart?

Some studies suggest that resveratrol in red wine may play a role in preventing blood vessel damage, reducing LDL cholesterol and preventing blood clotting. But most of the studies about resveratrol are based on animal experiments, and whether or not it has the same effect on humans is inconclusive.

Still other researches have shown that we probably should not be too optimistic about resveratrol. Studies have found that resveratrol may impair the benefits for the heart from physical exercise. Moreover, it works only in a short period of time after drinking wine.

Is there any danger in drinking wine to prevent heart disease?

At least the American Heart Association and the American Heart, Lung and Blood Institute have never recommended people to prevent heart disease by wine-drinking.

It’s easy to get addictive to alcohol. And excessive intake of it is often negligible. The risk brought by alcohol abuse is far greater than the uncertain benefits.

The danger of excessive drinking:

  1. Increasing the risk of high blood pressure, high triglycerides, liver damage and obesity;
  2. Alcohol is closely related to the incidence of esophageal cancer, colorectal cancer, breast cancer and other cancers;
  3. Frequent excessive drinking can cause cardiomyopathy.
  4. Pregnant women and people who have heart failure or take aspirin every day cannot drink alcohol. Do not expect to treat cardiovascular disease by drinking wine
