Man’s love for alcohol is truly immortal: archeologists have discovered that our love affair with green snake began about 9000 years ago. Evidence of alcohol consumption found in almost every society throughout history. Today the culture of drinking alcoholic beverages is also present in almost all countries of the world. This is despite the results of numerous studiesaccording to which the use of even small doses of alcohol is harmful to health. Moreover, according to the world health organization (who) and International Agency for research on cancer, alcohol belongs to the 1st group of carcinogens, along with tobacco Smoking. Really, even a small glass of beer or wine increases the risk of cancer? Scientists believe that, Yes.
Moderate alcohol consumption is harmful to health
According to data from the who because of excessive alcohol consumption in the world annually kills about three million people. A number of recent studies have linked increased risk of cancer with what many call a moderate consumption of alcohol. For example, in 2015, scientists from Harvard published the results of a studyin which experts have observed over the health of 88 084 women and 47 881 man for 30 years. They found that light or moderate drinking is associated with an increased risk of cancer. Recall that moderate alcohol consumption for men is the use of not more than 40 g pure alcohol per day (about 2 bottles of beer, 100 ml of vodka or 3 glasses of dry wine). And for women 30 grams of pure alcohol (1.5 bottles of beer or 80 grams of vodka, 2 glasses of dry wine). It turns out that even one bottle of beer a day increases the risk of cancer.
The same study revealed a particularly high risk of cancer in women. So, regular consumption of alcohol increases the risk of breast cancer by 13%. Two alcoholic drink a day also increased the risk of cancer among male smokers. However, the study found no higher risk among those who never smoked. Moreover, according to the results of a meta-analysis of 700 studies of 2018, any amount of alcohol is harmful to health.
Why alcohol is carcinogenic?
The researchers associated with alcohol such cancers as breast cancer, colon, rectum and liver, and cancer of the oral cavity and esophagus. Moreover, a recent study in mice sheds light on the mechanisms underlying exactly how alcohol causes cancer. As the body processes the alcohol, it turns into acetaldehyde, a highly toxic substance and known carcinogen.
Acetaldehyde continually damages the DNA in stem cells of the blood, which leads to a restructuring of chromosomes and frequent changes of DNA sequence. And damaged DNA can lead to cancer. Also alcohol may impair a person’s ability to absorb nutrients from food and increase the levels of estrogen, the female hormone associated with the development of breast cancer. However, the risk of the use of alcohol is not universal. Some heavy drinkers do not develop cancer, while those who consume moderate amounts of alcohol may eventually develop cancer. The researchers believe that it can be affected by genetic differences that determine how the body breaks down alcohol.
