Alcohol and Your Heart: Helpful or Harmful?

The effect of alcohol on health is complicated. Research is still being done to find out how alcohol affects the heart. At this time, most experts don't recommend that nondrinkers start drinking alcohol to improve cardiovascular health. All experts agree that drinking too much alcohol is related to many health problems.

Findings in recent years suggest that drinking alcohol in moderation may offer some people a degree of protection against heart disease. Studies have found that the risk of heart disease in people who drink moderately is lower than in nondrinkers.

What Is Moderate Drinking?

How much is one drink?
12 ounces of regular beer (150 calories)
5 ounces of wine (100 calories)
1.5 ounces of 80-proof hard liquor (100 calories)

The Dangers of Alcohol

Drinking too much alcohol can be dangerous. It can raise blood pressure and contribute to heart failure, stroke, high cholesterol, cancer, cirrhosis, and other diseases. Drinking alcohol during pregnancy can lead to serious problems for the baby. Alcohol can interact with some medicines, so talk with your doctor about any medicines you're currently taking.

Heavy drinking can also cause problems with personal relationships and work performance, and affect motor skills such as driving and operating machinery. For anyone with a personal or family history of alcoholism or liver disease, even occasional alcohol use can increase health risks.
