The nutritional effects and functions of wine, the benefits of drinking wine

Wine is a romantic foreign wine. What are the effects and functions of wine ? Do you know about it? Let's learn it together.

Nutritional effects of wine

Wine is a high-end beverage with multiple nutritional ingredients. Moderate drinking of wine can directly affect the human nervous system and improve muscle tension. In addition, the various amino acids, minerals and vitamins contained in wine can be directly absorbed by the human body. Therefore, wine can play a good role in maintaining and regulating the physiological functions of the human body. It is especially effective for people with weak bodies, sleep disorders and the elderly. It can be said that wine is a good tonic.

- Wine aids digestion

After drinking wine, if there is 60 ml - 100 ml of wine in the stomach, the amount of gastric juice formed can be increased to 120 ml.

Wine helps medicine

In addition, the tannin in wine can also adjust the contractility of smooth muscle fibers in the intestinal muscle system, adjust the function of the colon, and have a certain effect on colitis. Although the nutritional value of wine is very high, it is a kind of wine after all, and it always has a certain alcohol content. Therefore, no matter how effective wine is, it should not be consumed excessively. Otherwise, it will damage the body's immune function and increase the chance of illness.

Benefits of drinking wine

The first is to delay aging:

The human body, like metal, will gradually "oxidize" in nature. The culprit of human oxidation is not oxygen, but oxygen free radicals, which are active groups outside the cell nucleus containing unpaired electrons. These unpaired electrons can easily cause chemical reactions, damage important biological molecules such as DNA (deoxyribonucleic acid), proteins and lipids, and then affect the cell membrane transport process, causing damage to the functions of various tissues and organs, and promoting the aging of the body. Red wine contains more antioxidants, such as phenolic compounds, tannic acid, flavonoids, vitamin C, vitamin E, trace elements selenium, zinc, manganese, etc., which can eliminate or fight against oxygen free radicals, so it has anti-aging and disease prevention effects.

The second is to prevent cardiovascular and cerebrovascular diseases:

Red wine can increase the high-density lipoprotein (HDL) in the blood. The function of HDL is to transport cholesterol from extrahepatic tissues to the liver for metabolism, so it can effectively lower blood cholesterol and prevent atherosclerosis. In addition, the polyphenols in red wine can inhibit platelet aggregation and prevent thrombosis. Although white wine also has an anti-platelet aggregation effect, it will "rebound" after a few hours, making platelet aggregation more hyperactive than before drinking, while red wine does not have this rebound phenomenon. It can continue to inhibit platelet aggregation 18 hours after drinking.

The third is to prevent cancer:

Resveratrol contained in grape skin has the best anti-cancer properties among hundreds of plants commonly eaten by humans. It can prevent normal cells from becoming cancerous and inhibit the spread of cancer cells. Among all kinds of wine, red wine has the highest content of resveratrol. Because resveratrol can make cancer cells lose their ability to move, red wine is a good choice for preventing cancer.

The fourth is the beauty and skin care effect:

Since ancient times, red wine has been loved by people as a beauty product. Some people say that the delicate, moist and elastic skin of French women is related to the frequent drinking of red wine. Red wine can prevent aging and reduce wrinkles on the skin. In addition to drinking, many people like to apply red wine on the face and body because the low concentration of fruit acid has the effect of anti-wrinkle and skin cleansing. Although there are many benefits of drinking red wine, there is also a limit on the amount. Experts believe that drinking red wine, calculated based on an alcohol content of 12%, should not exceed 250 ml per day, otherwise it will harm health.

American researchers analyzed data from more than 70,000 middle-aged men, and 210 of them were diagnosed with lung cancer over a four-year period. The study found that drinking beer, white wine or alcoholic beverages was not associated with the incidence of lung cancer, but as these people consumed more red wine, the risk of lung cancer gradually decreased, with each additional glass of wine per month correspondingly reducing the risk of the disease by about 2%.

The cold wind brings winter, and this season is the best time for the human body to preserve its health. The human body is affected by the cold temperature, and various physiological functions and appetite will change. How can we adjust our body condition and survive the winter smoothly? Life Home has specially launched a series of articles on winter health guides, which provide you with comprehensive information on winter health care, so that this winter will no longer be cold!

Wine reduces lung cancer risk

Drinking a small amount of red wine every day has many benefits, but recent studies have found that drinking red wine can also reduce people's risk of lung cancer.

This should be good news for male smokers: drinking a glass of red wine a day may reduce the risk of lung cancer by 60% (compared to male smokers who do not drink red wine).

Dr. Arthur Kolatsky, a cardiovascular disease expert in Oakland, California, USA, carefully observed that most of the heart disease patients he met never drank alcohol. Later, he systematically studied the heart disease patients at the Kessel Health (Health Food) Center in North Carolina. From the analysis of the mortality rate of heart disease, drinkers were significantly lower than those who abstained from alcohol. Harvard Medical University in the United States also observed from research data that regular consumption of red wine can reduce the mortality rate of heart disease by 70%, and pointed out that moderate consumption of red wine can improve the quality of life of normal people.

The reason is that red wine is beneficial to increasing the content of high-density lipoprotein (IIDL) in the blood, that is, the content of good cholesterol, so that it can adjust to a mutually beneficial and benign relationship with low-density lipoprotein (LDL), that is, bad cholesterol. It plays a very important positive role in preventing and treating coronary heart disease caused by atherosclerosis.

Experts from the Paris Disease Prevention Center in France further pointed out that wine also contains a natural lipid, which plays a beneficial role in the normal metabolism of the human body, can lower the total cholesterol level, and has an anti-coagulant effect, which can inhibit thrombosis and thus prevent the formation of cardiovascular and cerebrovascular embolism.

Wine prevents diabetes

Moderate drinkers are 40% less likely to develop type 2 diabetes than those who do not drink at all. However, researchers pointed out that the preventive effect of moderate drinking on diabetes requires two major conditions: first, you must adhere to a healthy lifestyle, including a balanced diet, normal weight, moderate exercise, and no smoking; second, strictly control your drinking, preferably low-alcohol, low-sweetness wine, with women drinking no more than one glass a day and men no more than two glasses a day.

If diabetic patients drink alcohol, they must pay attention to the following points:

1. Good blood sugar control, no chronic diseases of other important organs and diabetic complications;

2. Do not inject insulin or take oral sulfonylurea hypoglycemic drugs;

3. Normal liver function;

4. Eat when drinking to avoid hypoglycemia;

5. Alcohol consumption: No more than 100-150ml of wine each time; no more than 350ml of beer, and no drinking of liquor. The above amount of alcohol is approximately equivalent to 25g of staple food, which should be subtracted from the diet plan. Do not drink more than 2 times a week.

Drinking red wine is a fashion in today's world. In 1998, the global wine trade suddenly increased significantly, and the total output of grape wine (grape food) in the world reached 22.5 billion liters, of which red wine accounted for about 75%. In 1999, it increased by about 10% over the previous year.

This number is astonishing. Its efficacy reveals that drinking red wine can not only keep fit, but also prevent disease. Some doctors say that red wine is better than aspirin in preventing and treating cardiovascular diseases.

Some experts from the Copenhagen Preventive Medicine Research Month in Denmark mentioned that they had conducted a 16-year follow-up observation study on 13,000 people who regularly drank red wine, and confirmed that the stroke rate of these people was 34% lower than that of those who did not drink red wine. This is because red wine contains certain plant compounds that are beneficial to health, including hydroxy acids, flavonoids and polyphenols.

These substances can act as antioxidants, helping to prevent fat from sticking to the arterial blood walls and clogging the arteries. Some experts also pointed out that it is important to drink red wine basically when eating. This way of drinking makes it easier for the active ingredients in the wine to be absorbed. It also reduces the stimulation of ethanol on the gastrointestinal tract.

Recently, the British magazine New Scientist published an article introducing that red wine contains resveratrol, which can increase the activity and effectiveness of an enzyme called "Max-Kinas" in the human body by 7 times. This enzyme can stimulate the regeneration of nerve cells in the human body. Experiments have shown that resveratrol can promote the growth of human brain nerve cells and enhance the connection between cells.

This discovery has positive significance for the prevention of Parkinson's disease and Alzheimer's disease, because the connection between brain nerve cells of patients with these diseases is often interrupted or blocked, resulting in confusion, slow thinking, loss of action and unclear speech. Experts from the University of Milan recommend that elderly people drink 1 to 1.5 small glasses of red wine every day to prevent the above diseases.

At present, doctors in some European countries also widely use wine as an auxiliary treatment for lung disease, liver disease and kidney disease. This is probably a unique and strange effect among alcoholic beverages.

Carmen de la Torre, a professor of nutrition at the University of Barcelona, pointed out that "red wine contains benzoic acid, cinnamic acid and other antioxidant components derived from tyrosine, which, after metabolism, are beneficial to enhancing the body's immune function and preventing the oxidation process and the release of free radicals." She also mentioned that people who drink 9 to 34 grams of red wine every day have a significantly lower incidence of cardiovascular disease than those who do not drink red wine.

Clinical trials have shown that drinking red wine is very effective in preventing blindness caused by cataracts and Alzheimer's disease in the elderly. But De La Torre stressed: "Red wine is a drink, not a medicine; therefore, it is difficult to make clear regulations on the way and amount of drinking. But one thing must be made clear: do not drink it on an empty stomach in the morning, because the blood alcohol level is higher in the morning. It is best to drink it at dinner. Drinking red wine can produce an anti-thrombotic effect in the human blood, which is better than taking aspirin, because taking aspirin can cause stomach discomfort.

Drinking red wine may prevent breast cancer

The American magazine "Cancer Research" reported that scientists at the "Hope" Cancer Research Center in Los Angeles extracted a chemical component called "proanthocyanidin B dimer" from red wine and found that this component can reduce the breast cancer tumors of experimental mice. Scientists said that there are many synthetic drugs on the market that can inhibit breast cancer by regulating the estrogen level in women (female food), and the proanthocyanidin B dimer extracted from red wine is a natural substance with the above effect. According to statistics, among menopausal women in the United States, 75% of breast cancer cases are caused by high estrogen levels in the body, so hormone suppression therapy has received more and more attention.

Scientists say that although the proanthocyanidin B dimer extracted from red wine is not as effective as synthetic drugs in fighting breast cancer, drinking red wine in moderation is also a good way to prevent breast cancer. Women who drink a glass of red wine every day may keep them away from the threat of breast cancer. However, scientists emphasize that drinking white wine is not helpful in preventing breast cancer because the anti-cancer chemical components they extracted from red wine originally come from grape skins.

Red wine helps lower cholesterol

Red wine contains chemicals that can lower cholesterol, researchers announced at the annual meeting of the American Chemical Society. The health benefits of red wine have long been known. It was previously believed that drinking red wine reduced the risk of heart disease because of the antioxidants in the grapes. But researchers at the University of California, San Diego, say other chemicals in red wine may also be good for health.

People have long known that saponins contained in plants can help lower cholesterol, and grape skins contain saponins. After comparing four red wines and two white wines, researchers at the University of California found that the California Zinfandel red wine with the highest alcohol content also had the highest content of saponins, while the white wines contained relatively less saponins.

The reason for this phenomenon is said to be that red wine is made from grapes with skins, while some white wines are made from grapes without skins. It is not clear how saponins lower cholesterol, but scientists speculate that it may be because the body cannot absorb saponins after they attach to cholesterol.

Red wine is good for your lungs

In recent years, people have gradually come to realize that red wine is good for the heart. Recent scientific research has brought good news that red wine also has a positive effect on nourishing and protecting the lungs. Researchers have found that red wine contains a natural compound that can help treat chronic bronchitis and emphysema. This compound called resveratrol is found in the skin of red grapes and can inhibit the production of harmful chemicals that cause lung diseases. Researchers said that according to statistics from the World Health Organization, chronic obstructive pulmonary disease kills 2.9 million people in the world every year. Among them, the number of people who suffer from chronic obstructive pulmonary disease due to smoking is ten times that of non-smokers.

The researchers took lung fluid samples from 15 smokers and 15 patients with COPD and added resveratrol to the samples. They found that resveratrol reduced the production of interleukin-8, a chemical that causes lung inflammation. The results showed that in smokers, the production of this harmful substance was reduced by 94%, while in COPD patients it was reduced by 88%.

Researchers said that currently doctors generally use steroid drugs to treat COPD. But according to the experimental results, resveratrol seems to be more effective. Although resveratrol cannot reverse the damage already caused to the lungs, it can prevent it from getting worse.

Drinking red wine in moderation can reduce the risk of Alzheimer's disease

Scientists have long pointed out that drinking one or two small glasses of red wine a day can protect the heart and reduce the risk of coronary heart disease and arteriosclerosis. New research shows that drinking red wine can also protect the brain from Alzheimer's disease.

The research team led by Dr. Egemen Savaskan of the University of Basel in Switzerland found in an experiment that red wine contains a lot of a substance called resveratrol. The experiment showed that this substance has a significant antioxidant effect, which can reduce the abnormal accumulation of beta-amyloid in brain cells and play a role in protecting brain cells. The general view is that excessive accumulation of beta-amyloid in brain cells will damage brain cells and cause the occurrence of Alzheimer's disease.

Benefits of wine:

The composition of red wine is quite complex. It is a fruit wine brewed through natural fermentation. It contains the most grape juice, accounting for more than 80%, followed by alcohol naturally fermented from the sugar in the grapes, generally 10% to 13%. The remaining substances exceed 1,000 kinds, and more than 300 kinds are relatively important. Other important ingredients of red wine include tartaric acid, fruitiness, minerals and tannins. Although the proportion of these substances is not high, they are the decisive factors for the quality of wine. High-quality and delicious red wines are because they can present a balance of organizational structure, which gives people endless enjoyment in taste. Wine is not only a solution of water and alcohol, it has rich connotations:

A. 80% water. This is biologically pure water, which is directly drawn from the soil by the grapevine. B. 9.5-15% ethanol, the main alcohol. Obtained through the fermentation of sugar, it is slightly sweet and gives the wine a mellow taste. C. Acid. Some come from grapes, such as tartaric acid, malic acid and citric acid; some are produced by alcoholic fermentation and lactic acid fermentation, such as lactic acid and acetic acid. These main acids play an important role in the acidic flavor and balanced taste of wine. D. Phenolic compounds. 1 to 5 grams per liter, they are mainly natural red pigments and tannins, which determine the color and structure of red wine. E. 0.2 to 5 grams of sugar per liter. Different types of wine contain different amounts of sugar. F. Aromatic substances (hundreds of milligrams per liter), they are volatile and there are many types. G. Amino acids, proteins and vitamins (C, B1, B2, B12, PP). They affect the nutritional value of wine. Therefore, drinking wine in moderation is beneficial to human health. It can protect blood vessels, prevent arteriosclerosis and lower cholesterol.

Medical research shows that grapes are very nutritious, and wine made from grapes also contains a variety of amino acids, minerals and vitamins, which are nutrients that the human body must supplement and absorb. At present, there are about 600 known ingredients in wine that are beneficial to the human body. The nutritional value of wine has also been widely recognized. According to experts, the roots of grape trees over 25 years old are deeply rooted in the underground soil, and they absorb more mineral trace elements. The wine brewed from this fruit has the most nutritional value.

Of course, everything should have a "degree". The resveratrol in red wine can protect brain cells, but excessive absorption of the alcohol contained in the wine can also damage brain cells. Therefore, you should not drink too much red wine, let alone alcoholism. It is better to drink one or two small glasses a day.
