At the beginning of this year, a new paper in the top magazine Nature was widely reprinted around the world: researchers at Cambridge University found that alcohol and its metabolite acetaldehyde had a significant impact on hematopoietic stem cells through animal models.

The reason for his concern is that drinking can cause cancer: drinking can cause cancer! China people are particularly dangerous! Recently, Nature magazine published an article saying that alcohol and endogenous aldehydes damage chromosomes and mutant stem cells, which proves once again that drinking alcohol is closely related to cancer incidence and death.

The researchers made the mice drink a lot of alcoholic drinks without knowing it. Under the action of alcohol, the instability of DNA becomes more and more serious. Alcohol and its metabolites will have disastrous consequences for DNA. However, it is worth noting that most people do not contain genes that can eliminate alcohol, but they can achieve their goals through self-explanation. Asians account for a lot of these 540 million people-many people around us will blush when drinking, which is a manifestation of insufficient acetaldehyde metabolism. These friends who drink alcohol are also more prone to DNA damage under the influence of acetaldehyde, an alcohol metabolite, leading to blood diseases and even cancer.

However, this does not mean that alcohol can be drunk casually. We should give up drinking. "Our research shows that insufficient alcohol metabolism will lead to a higher risk of related DNA damage and lead to cancer. But it is also important to remember, "Professor Patel added," that the alcohol removal and DNA repair systems are not perfect. Even among these people with complete defense mechanisms, alcohol can still cause cancer in many ways. "

Everyone agrees that tobacco causes cancer, but many people don't seem to accept it emotionally. Look at the evidence thrown by the researchers:

1. Ethanol, the main substance in alcohol, can damage DNA；; 2. Acetaldehyde produced by ethanol metabolism in the body is a carcinogen and will also damage DNA；; 3. Alcohol may affect the decomposition of estrogen and increase the estrogen content in the blood, which is more likely to cause breast cancer, ovarian cancer and uterine cancer, especially for postmenopausal women;
