Drinking alcohol in small amounts is not healthier. Alcohol enters the body to be broken down and metabolized by the liver, so as long as you drink alcohol, you will increase the metabolic and detoxification burden of the liver. Even if a small amount of alcohol is consumed, the cumulative effect of the amount of alcohol over a long period of time may damage the function of liver cells, so a small amount of alcohol is not healthier. Alcohol also causes nervous system hyperfunction, especially the visceral nerves in the sympathetic nerve excitability is higher than the parasympathetic nerve, easy to cause elevated blood pressure, not conducive to cardiovascular and cerebrovascular health. Alcohol metabolites will be dissolved in the urine and excreted through the kidneys, so there is also chronic damage to kidney function by drinking alcohol. In addition, alcohol into the stomach may burn the gastric mucosa, is a chronic superficial gastritis, gastric ulcer and other digestive tract diseases predisposing factors. Therefore, for those who have the habit of drinking alcohol, it is important to control the amount to minimize the damage of alcohol to the body.
