In the clinic, I often have elderly friends ask me: doctor, they say that drinking red wine is good for blood vessels, can I drink a glass of red wine every day? Generally encountered such a question, my answer is: there is no definitive evidence to confirm that a glass of red wine is good for the cardiovascular, but there is a glass of red wine alcohol, affecting the health of the trial. The following is a detailed description of the relationship between red wine and heart health. It has long been believed that red wine is good for heart health when consumed in moderation. If you just drink a small glass of red wine a day to accompany your meal, this does sound great. However, doctors must still not easily encourage people to drink alcohol, because too much alcohol may bring many side effects to the body. If red wine seems to improve heart health, it is mainly because it contains some antioxidants, such as flavonoids or a substance called resveratrol. There is no conclusive evidence that red wine reveals better benefits for heart health than other forms of alcohol. Resveratrol may be a key substance that red wine uses to help protect blood vessels from damage, lower “harmful” cholesterol levels and prevent blood clots. Many of the studies on resveratrol have been conducted in mice, not humans. To get the same dose of resveratrol as in the mouse study, a person would need to drink more than 60 liters of red wine per day, which is certainly not possible. 60 liters of red wine is about 120 pounds, and no one can drink that much red wine, and at 12% alcohol, that 60 liters of red wine would give you severe alcohol poisoning. The resveratrol in red wine comes from the skins of the grapes used to make red wine. Because red wines take longer to ferment on the skins than white wines, red wines contain more resveratrol. But it’s also a drop in the bucket for health. Although researchers have not found any harm caused by taking resveratrol, the resveratrol in most supplements is not absorbed by the body. Alcohol consumption is undoubtedly an unhealthy diet, and recent studies have confirmed that any dose of alcohol intake is damaging to the body. Alcohol can also be addictive or trigger other more serious health problems. Drinking too much alcohol increases the risk of high blood pressure, high triglycerides, liver damage, obesity, certain cancers, accidents and other problems. In addition, regular excessive alcohol consumption can trigger alcoholic cardiomyopathy, which can lead to symptoms of heart failure.
