It is said that moderate drinking can reduce the incidence of some diseases. What are those?

The history of human understanding of wine is as long as that of human beings. Some people with ancient culture once believed that grape cultivation and wine were given by God, so they compared "moderate drinking" to "the second life of mankind".

Is wine really good for health? Many people think that drinking will lead to unhealthy health, but more and more facts show that moderate drinking can indeed reduce the incidence of many diseases.

Scientists point out that people who drink a small or moderate amount of alcohol live three to four years longer than those who don't drink at all. People who drink 1 2 glasses of wine every day also have a lower overall mortality rate of 40 percentage points than those who never drink. It would be better if you drank a little more. Compared with people who don't drink, the death rate of people who come to three or five glasses of wine every day is reduced by half.

Let's look at some examples to understand why moderate drinking can reduce the incidence of some diseases.

(a) Reducing fat deposition to prevent and treat cardiovascular diseases

The first popular research appeared in the early 1990s, and it was called the "French miracle". The experiment was conducted by French epidemiologist Serge Reynolds. The results show that although the French eat a lot of greasy food in their daily diet, the incidence of heart disease in France as a whole is lower than that in other western countries, and the study also points out that this is directly related to human life span.

If you want to eat greasy food, please do yourself a favor: use wine with a high-fat diet to balance the pathogenic factors. A high-fat diet will accelerate the formation of blood clots, which will block blood vessels, cause stroke and heart disease, and lead to death. The experiment was carried out with two groups of mice. Mice drinking red wine are 60% lower than those drinking water.

In Chile, an experiment involving 44 young men achieved similar results. These volunteers eat high-fat food, just like ordinary people in western industrial countries. They have been eating this kind of food for three weeks. During this period, they first drink a glass of white wine every day, then a glass of red wine every day, and finally eat 8 extra servings of fruits and vegetables every day, but don't drink alcohol.

This study shows that both red wine and white wine can increase high concentration of fatty protein, referred to as HDL, or "good cholesterol", which is a substance that can clean arteries. This further proves that moderate drinking can prevent heart disease, and red wine is more effective. In this experiment in Chile, compared with those volunteers who only ate greasy food, the food cholesterol level of volunteers who drank a glass of red wine every day increased by 14%.

The researchers also measured the DNA damage of volunteers caused by oxidation caused by fatty foods. Drinking red wine can reduce the damage to DNA caused by oxidation caused by greasy food by half; Liquor can reduce 16%.

The natural flow of blood is beneficial to the human body, and the researchers also measured the blood vessel diameter of volunteers. Red wine can obviously enlarge the diameter of arteries, enhance the function of arterial endothelial cell layer, and actually make arteries healthier.

The first experiment to reveal that wine is particularly beneficial to health dates back to 1979. This study investigated the health status of men and women aged 55 to 64 in 18 countries. It was found that alcohol can reduce the risk of heart disease by 30%, and the author attributed it to wine.

1995 there is a study on the heart state of 605/kloc-0 men and 7234 women aged 30 to 79 in Copenhagen. Compared with people who never drink alcohol, people who drink three to five drinks a day have a 60% lower risk of heart disease and stroke. In the past 20 years, the alcohol consumption of Danes has increased by 30%, and their probability of heart disease has also decreased by the same percentage point, which seems to give people sufficient reasons to follow the example of Danes.

Britain also conducted a heart disease study involving 6680 men, which lasted 17 years, and studied their health status and drinking habits. The results show that people who drink wine are 30% less likely to suffer from heart disease than those who drink beer and spirits. Drinking wine (instead of spirits) can reduce the death rate caused by excessive intake of alcohol by 20 percentage points.

It is found in France that people who drink three to five glasses a day have a one-third to two-thirds lower risk of heart disease than those who only drink beer or spirits.

Italians found that people who drink one or two glasses of wine a day in a standard glass are 34% less likely to have a heart attack than those who never drink.

Although the results of various experiments conducted in Europe are different from those recently obtained in the United States, a large part of them are the same, that is, people who drink two to four glasses of wine a day are 20% to 60% less likely to suffer from heart disease than those who don't drink. A study also shows that people who drink three or four days a week are 30% less likely to suffer from heart disease than those who drink only one day or less a week.

The reason why red wine is different from other alcoholic drinks and water is that it contains a lot of polyphenols. Scientists are interested in this because polyphenols contain a lot of antioxidants. As we all know, antioxidants can resist some diseases. This substance is abundant in the stems, seeds and skins of grapes. And red wine is fermented with these grape skins rich in polyphenols. In fact, the concentration of antioxidants in mice fed with red wine is three times that of mice fed with spirits. Antioxidants, flavonoids and other "broader factors" in wine explain why wine itself has such an obvious effect on reducing mortality.

(B) moderate drinking to prevent the formation of cancer cells.

Moderate drinking of wine can also reduce the incidence of many cancers, including breast cancer, prostate cancer, laryngeal cancer and lung cancer.

In 2000, a laboratory research report was published in the Journal of Cell Biochemistry. In this study, the effect of polyphenols extracted from red wine on the proliferation of breast cancer cells was tested. The test results show that moderate drinking can inhibit the growth of breast cancer cells.

Ilias Casta, a biochemist and doctor of philosophy, found that drinking 1 2 glasses of red wine every day can prevent breast cancer and prostate cancer. In his laboratory in Crete, he used polyphenols, such as quercetin, to inhibit cancer cells. He found that quercetin extracted from French wine can effectively inhibit the spread of prostate cancer cells, and the dose is very small, which is only equivalent to the amount contained in two glasses of red wine every day.

A group of Spanish researchers have concluded that the compounds contained in red wine can not only inhibit the spread of prostate cancer cells, but also help destroy cancer cells. Dr Ignacio Romero, chief scientist from the Medical Center of Getafe University in Madrid, said: Based on the laboratory culture of prostate cancer cells, we found that the compounds extracted from red wine here have obvious inhibitory effects on cultured prostate cancer cells, and even stimulate the cells to self-destroy.

French epidemiologist and nutritionist Serge Lei Nuode found that people who drink 1 to 3 glasses of wine a day will reduce the cancer-related mortality by 20% to 22%.

In 2000, Danish epidemiologist Morten Gronbaek also conducted a new experiment related to cancer. It was found that people who drink 1 3 cups a day have a lower risk of cancer than those who don't drink. People who drink beer and spirits have a slightly higher risk of cancer than those who never drink.

In some articles published in the following years, Globeck and his colleagues affirmed that drinking wine is more beneficial to health than drinking beer and spirits. People who drink wine are significantly less likely to develop laryngeal cancer and lung cancer than those who drink beer and spirits, and even the possibility of fracture is usually slightly lower.

A large number of polyphenols in red wine has become a key factor. As we all know, polyphenols have antioxidant effect, which reduces the damage and speed of our body to oxidation, especially cancer.

Some British scientists believe that they have found something to reverse the inhibitory effect of anticancer substances on tumors. These substances exist in red wine and nuts, and their preventive effects on cancer have long been known.

Researchers from the United States Department of Agriculture have discovered another anticancer compound contained in grapes. They say that this compound called Dieqi is very similar to anticancer substances, and it is also an antioxidant recently found in grapes and red wine, which also has the effect of preventing cancer.

(3) appetizing and invigorating the spleen

Wine is fermented from pure grape juice. The natural acidic substances in grape juice are all dissolved in wine, and their acidity is close to gastric acid (pH 2-2.5). Therefore, wine, as a good seasoning, can help protein to digest and absorb. If you drink alcohol in moderation before meals, it can also promote the secretion of pancreatic enzymes, thus enhancing the digestion and absorption of food in the gastrointestinal tract. Therefore, drinking before meals, especially for middle-aged and elderly people, can enhance the digestive function and is very beneficial to the body.
