Polyphenols, that's why wine doesn't hurt.
Polyphenols are chemicals found in many plants, including grapes and wine, that are known for their antioxidant and anti-inflammatory properties. These compounds may help prevent or reduce cellular damage caused by free radicals and have a protective effect on heart and arterial health. Wine polyphenols include flavonoids such as resveratrol and tannins, which give wine a tart or astringent taste. However, it's important to note that excessive alcohol intake can have adverse health effects, so wine consumption should be in moderation.
