Red wine contains resveratrol, which is found in grape seeds. Studies have shown resveratrol, a plant phenol, to have many naturally beneficial properties, especially in anti-aging and heart disease prevention.
Resveratrol is present in red wine and is a substance produced during the wine fermentation process. It can help change blood cholesterol levels by increasing HDL levels and preventing blood clotting. Therefore, moderate consumption of red wine can help lower risk of heart disease by 30-40%.
It was further found that resveratrol has indirect benefits in strengthening skin cells, making them resistant to sunlight exposure (which contains UVA and UVB rays), and helps protect the skin from free radicals from sunlight exposure.
The right way to consume red wine is to consume no more than 2 glasses per day (2 glasses per day for men and 1 glass per day for women). If you drink more than 250 cc, you will be doing more harm than good, because wine also contains alcohol.
