The notion that drinking in moderation is good for your health is false. A large number of authoritative studies now show that the safest amount of alcohol to drink is zero. In other words, the safest thing to do is not to drink, and if you must drink for any reason, it is recommended that both men and women keep their intake of pure alcohol to less than 15 grams. Drinking large amounts of alcohol over a long period of time is detrimental to health, mainly in terms of damage to the central nervous system, the digestive tract, and organs throughout the body. Alcohol, especially high alcohol intake, can directly stimulate the digestive tract, causing damage to the mucous membrane of the digestive tract, and in severe cases can even cause gastritis, gastric ulcer. At the same time, the metabolism of alcohol is mainly through the liver, a large amount of alcohol will trigger liver cell apoptosis, affecting liver function. Alcohol in its decomposition and metabolism produces a large amount of acetaldehyde, acetaldehyde is a strong carcinogen, can cause liver cancer, stomach cancer and other organs malignant tumors. To summarize, drinking in moderation is good for health is a false statement.
