Drinking 2-3 glasses of wine every day can greatly reduce the incidence of cardiovascular diseases. Wine contains a variety of amino acids, vitamins and minerals, as well as tannins, pectin and tartaric acid that other wines do not have. Wine is the only wine that reacts in the gastrointestinal tract, which is beneficial to adjust the acid-base ratio of food components, so it has medical value such as "filling the stomach" to help digestion, promoting metabolism and improving cardiovascular and cerebrovascular physiological functions. Wine contains organic acids and amino acids closely related to human body. Wine also contains a variety of vitamins, which can ensure the normal growth and development of the body, maintain various physiological activities in the body and improve resistance. The acidity of wine is close to human gastric acid, which is a suitable condition for protein's digestion. Therefore, wine is the best table drink containing protein, which has a good medical effect on people with weak constitution. It is reported that French red wine not only has the function of preventing and treating cancer and heart disease, but also helps to maintain skin and prevent wrinkles. How much wine is good for human health? Weight should be taken as the reference standard, and normal people can drink up to 0.6 ~ 0.8 ml per kilogram of body weight. It is expressed by a simple formula: the maximum alcohol consumption is 0.6 or 0.8× body weight (kg )×100 ÷ alcohol. For example, if you drink 50 kg of 12 alcohol, you can drink 250 ~ 334 ml (5 ~ 7 ounces) at most each time; Drink 16 alcohol 190 ~ 250 ml (4 ~ 5 liang) at most each time. Drinking wine properly can make people feel happy, stimulate appetite and be beneficial to health. Medical experiments have proved that wine is good for health. Drinking red wine can produce a yeast called PST-PDE, which can prevent migraine, but more importantly, it can promote more HDL in the blood and lower cholesterol. Moreover, both red wine and white wine are beneficial to the digestion of the stomach. In recent years, red wine has become a fashion. Advocates of red wine plausibly point out that red wine is "good for health". This is not wishful thinking, but has a medical basis. As we all know, heart disease is still the "number one killer" today, especially for people who like to eat foods with high cholesterol. But red wine can increase a substance called HDL in human blood, and its function is to guide harmful cholesterol to leave the blood vessel wall and flow into the liver to be eliminated, thus reducing the risk of heart attack. In addition, red wine can also make people produce a yeast called PST-PDE, which has bactericidal effect and can also prevent migraine. People who study dietary nutrition in the west have a term called "French contradiction". "French contradiction" refers to the overeating French, and strangely, they live longer than Americans! French people eat foie gras, where is the cholesterol in their stomachs? Probably because French people eat red wine every day, so their cholesterol is low. Statistics over the years will not be groundless. It seems that this is the only explanation for this contradiction. Recently, the Cancer Institute of Thomas Jefferson Medical University conducted a comparative experiment to detect the antioxidant content in three famous red wines from Europe, America and Asia. The results show that Changyu dry red wine from China contains more antioxidants, which can prevent coronary heart disease and cancer. The experimental report shows that the content of tea phenol, the main component of red wine polyphenols, in Changyu dry red sample (100mg/ 1) is higher than that in France and the United States, and the content of other phenols in three samples is high or low, while the total amount of the three components is obviously higher than that in the other two samples. This test result gives the world a chance to know and confirm the healthy ingredients of China high-quality red wine. American scientists have found a phenomenon: the incidence of cardiovascular diseases in French people who are very similar to their own eating habits is much lower than that in Americans, and the only obvious difference between the eating habits of the two countries is that French people prefer to drink wine. So scientists reanalyzed this wine and found that it contains a lot of vitamins, protein and various amino acids. They also found a substance called tannic acid in wine. High density lipoprotein in red wine is anti-arteriosclerosis. In recent years, it has been found that tannic acid extracted from red wine is more effective in preventing and treating cardiovascular diseases. At present, cardiovascular disease is the biggest killer threatening human health, so middle-aged and elderly friends might as well insist on drinking a proper amount of red wine, which is a good way to protect themselves. In addition, many young friends are stressed and nervous at work now. So many people's health is not optimistic. They can also get into the habit of drinking wine from now on to calm their nerves and relieve stress. It is better to take care of yourself from an early age. It is said that drinking wine can also resist aging, which is amazing. Is it true?/You don't say. Red wine contains a substance called antioxidant free radicals. Because antioxidant free radicals can prevent the oxidation of fat in the body, if we can eat more antioxidant free radicals, the oxidation of fat will be prevented. Therefore, drinking wine is not only to prevent diseases, but also to delay aging for a long time. Although the raw material of wine is grapes, eating grapes can not achieve the health care effect of drinking. This is because the anti-aging free radicals in red grapes mainly exist in grape skins, so the effect of drinking fermented red wine with skins is of course different from that of eating grapes! So, how to choose the wine that suits you? Of course, you should consider your own taste before buying wine. Let's give you a brief introduction: red wine is fermented from red grapes and has a rich and aromatic taste; Of course, white wine is made from white grapes. It's refreshing. As for sweetness and sourness, it is not determined by the color of wine. The sweetness and sourness of wine are divided according to the sugar content of wine. For example, red wine can be divided into dry red wine, semi-dry red wine, semi-sweet red wine and sweet wine according to the different sugar content. So is white wine. So friends with diabetes can also enjoy wine. As long as you choose dry red wine and dry white wine with the least sugar content, you can keep healthy by drinking wine.
