Seriously, stop drinking! What are the disadvantages of drinking?

China people may have two completely different attitudes towards wine. Those who love it can't put it down, and those who hate it hate it. Of course, there may be a third attitude: I don't drink anyway, so I have no feeling about wine. Today, Ge Ping does not discuss the wine culture with a long history, but only talks about drinking from the perspective of health, or the influence or harm of alcohol to the human body. If you don't like it, don't spray it.

Alcohol is absorbed in the stomach and small intestine. Although one gram of alcohol can provide 7 kilocalories, it is different from the other three nutrients and must be regarded as an anti-nutrient, because excessive intake of alcohol will inhibit the normal metabolism of vitamins, thus inhibiting the normal metabolism of major energy substrates (carbohydrates, protein and fat).

From the perspective of nutrition and health, we need to make it clear that alcohol is not an essential nutrient, but a toxic substance? Although the human body has certain detoxification ability, other toxic substances will still be produced during detoxification. Specifically, alcohol has the following hazards to people:

1. Regular heavy drinking will increase the risk of the following diseases: liver cancer, oral cancer, laryngeal cancer and esophageal cancer (if smoking at the same time, the risk of the latter three cancers is higher), and liver cirrhosis (partial fibrosis and functional loss of the liver).

2. Alcohol is irritating to the whole gastrointestinal tract, so it will cause malnutrition. Alcohol can increase the excretion of calcium and magnesium in urine. Magnesium is an auxiliary factor of phosphotransferase, so it is an essential component of energy metabolism. Regular drinking will reduce the resorption of magnesium (increase the loss in urine) and increase the excretion of magnesium in sweat, which will lead to an increase in the incidence of muscle spasm, weakness and arrhythmia. The lack of magnesium caused by frequent drinking is an unbearable problem for athletes.

3. Alcohol can damage liver function and hinder the metabolism and storage of nutrients. In addition, the intake of alcohol will increase the body's demand for nutrients to repair the damage caused by alcohol and make up for its malabsorption.

4. Long-term alcoholism will weaken the function of the heart, make the brain and nerves dysfunctional, and increase the level of blood lipids (especially triglycerides), leading to fatty liver, liver cirrhosis (abnormal liver function) and pancreatitis (seriously affecting the regulation and digestion of blood sugar).

5. Besides increasing the risk of sports injury, there is sufficient evidence that drinking more than 1 cup every day will have a negative impact on reaction time, physical coordination and energy metabolism, thus affecting athletes' performance.

Why does alcohol increase people's cancer risk?

Alcohol dehydrogenase is an enzyme produced by the liver, and its function is to dehydrogenate the active form of vitamin A (namely retinol, an alcohol substance). However, after alcohol (ethanol) is ingested, limited alcohol dehydrogenase is diverted to treat ethanol, resulting in more vitamin A in the form of potentially toxic alcohol, leading to adverse interaction between alcohol and vitamin A, which may lead to hepatotoxicity and increase the risk of cancer.
