Wine and heart health

Alternative Names

Health and wine

Information

There is a fine line between healthy drinking and risky drinking. More studies are being done on the possible benefits wine (particularly red wine) may have on heart disease. However, it is a controversial topic.

There is some evidence that people who drink moderately may be less likely to develop heart disease than those who do not drink at all. However, drinking alcohol has been linked to:

Cancer
Heart failure
High blood pressure
Irregular heart rhythms (arrhythmias)
Liver disease
Motor vehicle accidents
Obesity
Physical abuse
Stroke
Suicide
Swelling of the pancreas (pancreatitis)

Alcohol abuse is associated with cancers of the:

Breast
Colon
Mouth
Rectum
Throat (pharynx)
Voice box (larynx)

In addition, although some studies suggest that alcohol may raise the good kind of cholesterol (HDL), it also raises a type of fat in the blood (triglycerides).

The American Heart Association and other experts say there are much more effective ways to prevent heart disease, including:

Controlling your blood pressure and cholesterol
Exercising and following a low-fat, healthy diet
Not smoking
Maintaining a normal weight

These tried and true methods have much more scientific proof supporting them than does drinking moderate amounts of alcohol. Furthermore, the benefits suggested by some of the studies on alcohol are likely due to other factors such as:

A diet high in fruits and vegetables
Antioxidants found in red wine called flavonoids (which are also found in other foods such as grapes and red grape juice)
More physical activity in countries that drink wine regularly

There is also a substance in alcohol known as resveratrol, which may reduce blood clot formation. However, taking aspirin following your doctor's instructions is a more standard method for lowering your chances of developing a blood clot if you are at risk for heart disease or stroke. Note: You should NOT drink alcohol if you take aspirin regularly.

Women should have no more than 1 drink per day. Men should have no more than 2 drinks per day. A drink is defined as:

12 ounces of beer
4 ounces of wine
1.5 ounces of liquor or 80-proof spirits

Even light drinking can lead to addiction. Pregnant women need to avoid alcohol consumption altogether because it can cause serious birth defects.
