Is Red Wine Good for the Human Body?

Red wine has long enjoyed a reputation as the healthiest alcoholic drink. From the vineyards of France to dinner tables around Australia, it has often been associated with heart health, longevity and the so-called Mediterranean lifestyle.

But does modern medical evidence support those claims?

Why Red Wine Was Considered Healthy

The belief that red wine offers health benefits comes largely from naturally occurring plant compounds called polyphenols. One of the best known is resveratrol, found in the skins of red grapes.

Researchers have suggested these compounds may help:

• Protect blood vessels from damage.
• Reduce inflammation.
• Improve cholesterol balance by helping maintain healthy HDL ("good") cholesterol.
• Reduce the formation of harmful blood clots.

These findings helped create the idea that a glass of red wine each day might protect the heart.

The Modern View

Health experts now take a more cautious approach.

While some studies have found that people who drink small amounts of red wine experience lower rates of certain heart diseases, it is difficult to know whether wine itself deserves the credit.

Many moderate wine drinkers also tend to:

• Eat healthier diets.
• Exercise regularly.
• Maintain healthier body weights.
• Have better access to healthcare.
• Smoke less than heavier drinkers.

These lifestyle factors may explain much of the apparent benefit.

The Downsides

Alcohol is still alcohol.

Regular or excessive consumption increases the risk of a range of health problems, including:

• Liver disease.
• Several forms of cancer, including breast, bowel, mouth and oesophageal cancers.
• High blood pressure.
• Heart rhythm disturbances.
• Weight gain.
• Sleep disruption.
• Accidents and injuries.

Even moderate drinking carries some level of risk.

Is One Glass a Day Safe?

Australian health guidelines recommend that healthy adults drink no more than 10 standard drinks per week and no more than four standard drinks on any one day. The lower the alcohol intake, the lower the health risk.

For some people, the safest choice is not drinking at all. This includes:

• Pregnant women.
• Children and teenagers.
• People taking certain medications.
• Those with liver disease.
• Anyone with a history of alcohol dependence.

Can You Get the Same Benefits Without Alcohol?

Fortunately, yes.

Many of the beneficial antioxidants found in red wine also occur in foods such as:

• Red and black grapes.
• Blueberries.
• Strawberries.
• Cherries.
• Peanuts.
• Walnuts.
• Olive oil.
• Colourful vegetables.

These foods provide antioxidants without the health risks associated with alcohol.

The Bottom Line

Red wine is not a health tonic, nor is it a miracle food.

For adults who already enjoy an occasional glass, there is generally no evidence that moderate consumption must be avoided solely because it is red wine. However, no one should start drinking alcohol in the hope of improving their health.

The strongest evidence for long-term wellbeing continues to point towards the familiar foundations: a balanced diet, regular exercise, adequate sleep, maintaining a healthy weight, avoiding smoking and keeping alcohol consumption low.

When it comes to good health, there are no shortcuts in a bottle.
