Red wine is a drink prized not only for its flavour and aromatic richness, but also for the potential health benefits it may offer when enjoyed in moderation.
These benefits are mainly linked to the antioxidants found in wine, such as resveratrol, which is present in the skins of the grapes used to make it. Here we take a closer look at the main properties of red wine and how they might contribute to your health.
The benefits of red wine
Red wine has been the subject of numerous scientific studies suggesting that moderate consumption may be linked to several positive health effects.
Heart health
One of the best-known benefits of red wine is its potential to improve cardiovascular health. Antioxidants such as resveratrol may help reduce the risk of heart disease by acting on inflammation and regulating lipids in the body.
Recent studies have indicated that moderate red wine consumption could be linked to a lower risk of coronary heart disease, one of the leading causes of death worldwide.
However, it's important to remember that too much alcohol can have harmful effects on the heart, so it's advisable to stick to moderate drinking guidelines.
Digestive health
Red wine may also contribute to the health of the digestive tract. The polyphenols in wine act as probiotics, encouraging the growth of beneficial bacteria in the gut.
This can improve the gut microbiota and, as a result, digestive health in general.
Although research in this area is still limited, studies suggest that the compounds in red wine could play a positive role in promoting a healthy gut.
Type 2 diabetes
In people with type 2 diabetes, moderate consumption of red wine with meals may help slightly reduce cardiometabolic risk, contributing to better blood sugar control.
However, these effects vary and are not conclusive, so it's crucial that people with diabetes consult their doctor before making red wine part of their regular diet.
Blood pressure
According to the American College of Physicians, the resveratrol in red wine has been linked to lower blood pressure and higher levels of HDL cholesterol ("good" cholesterol). This could help keep blood vessels healthy, reducing the risk of hypertension.
Nevertheless, it's important to point out that excessive alcohol consumption can raise blood pressure and cause arrhythmias, which underlines the importance of drinking in moderation.
Preventing brain damage after a stroke
Resveratrol could help protect the brain against secondary damage after a stroke, thanks to its anti-inflammatory and antioxidant effects.
Although much of the research has been carried out on animal models, these findings point to a potential benefit of resveratrol in the recovery of the central nervous system.
Preventing sight loss
Resveratrol could also help prevent age-related sight loss by reducing inflammation and oxidative stress, which are common factors in conditions such as glaucoma, cataracts and macular degeneration.
Risks and warnings
| Despite these potential benefits, it's essential to bear in mind the risks associated with drinking alcohol. Drinking too much can lead to serious health problems, such as heart disease, liver damage, certain types of cancer and mood disorders such as depression. In addition, alcohol can be especially harmful for people with pre-existing liver conditions or those prone to alcohol misuse. |
Is red wine or white wine better?
Red wine generally contains more resveratrol than white wine, as it's fermented with the grape skins, where this antioxidant is concentrated.
So red wine is usually the best choice if you want to make the most of the antioxidant benefits.
However, consumption should be moderate to avoid the negative effects associated with alcohol.
Conclusion
Enjoyed in moderation, red wine can be part of a healthy lifestyle thanks to its antioxidant properties and its potential benefits for the heart, the gut and the brain.
For those who want the benefits of resveratrol without the risks of alcohol, grapes and berries can be a safer and healthier alternative.
