Red wine contains a lot of polybasic acids, so it plays an excellent role in preventing cardiovascular diseases, helping to prevent diseases such as arteriosclerosis and Alzheimer's disease, and also has important functions such as reducing the risk of osteoporosis and "caring skin".
In the minds of ordinary people, enjoying life always seems to run counter to health. Wine has proved to us that enjoyment and health can be enjoyed at the same time, as long as it is not excessive. 1992, an epidemic broke out in the United States and Canada. Pathologist Selison pointed out: In France, people often eat high-fat foods, and the average cholesterol content of French people is not lower than that of other countries, but the death rate of heart disease in France is the lowest among industrialized countries, and the incidence rate is only 60% of that in the United States. The secret of living longer than that in the United States lies in frequent drinking.
First, the health function of wine
1, increase appetite
The bright colors and clear and transparent posture of wine are pleasing to the eye; Pour it into the cup, and the aroma of fruit and wine is fragrant; When tasting, the tannins in the wine are slightly astringent, which promotes appetite. All these make the human body in a comfortable and pleasant state, which is beneficial to physical and mental health.
2. Beautiful and beautiful
Since ancient times, red wine, as the best product in beauty beauty, has been loved by people.
For women, it can promote metabolism, remove oxygen free radicals, nourish skin tissue, and make women's skin more delicate, more energetic and more shiny. Some people say that French women have delicate, moist and elastic skin, which is related to frequent drinking of red wine. Red wine can prevent aging and make skin wrinkle less. In addition to drinking, many people like to apply red wine to their faces and body surfaces, because low concentration of fruit acid has anti-wrinkle and skin cleaning effects.
For men, red wine can promote blood circulation to remove blood stasis, eliminate fatigue, relax body and mind, help activate immune neural network, and play a role in slowing down the aging of reproductive system.
Although drinking red wine has many benefits, the quantity is limited. Experts believe that drinking red wine, according to the alcohol content 12%, should not exceed 250 ml per day, otherwise it is harmful to health.
3, delay aging
The human body, like metal, will gradually "oxidize" in nature. The culprit of human oxidation is not oxygen, but oxygen free radical, which is an active gene with unpaired electrons outside the nucleus. This unpaired electron can easily cause chemical reactions and damage important biomolecules such as DNA (deoxyribonucleic acid), protein, lipids, etc., and then affect the transport process of cell membrane, damage the functions of various tissues and organs, and promote the aging of the body. Red wine contains a variety of antioxidants, such as phenols, tannins, flavonoids, vitamin C, vitamin E, trace elements selenium, zinc, manganese, etc., which can eliminate or fight oxygen free radicals, so it has the functions of anti-aging and disease prevention.
4. Nourishing effect
Wine contains sugar, amino acids, vitamins and minerals. These are all essential nutrients for human body. Without pre-digestion, it can be directly absorbed by human body. Especially for the infirm, drinking a proper amount of wine often is beneficial to the recovery of the body. Phenols and trace elements in wine can act as oxidants, which can prevent the damage of reactive oxygen species (Ros) produced during human metabolism (such as DNA and RNA in cells), and are one of the factors leading to some degenerative diseases, such as cataract, cardiovascular disease, arteriosclerosis and aging. Therefore, drinking wine in moderation often has the effect of preventing aging and prolonging life.
5. Help digestion
Wine contains a variety of organic acids, slightly sour, similar to human acidity (PH2-2.5). This is a suitable condition for protein to digest, so wine is the best table drink with protein. Wine can stimulate gastric acid to secrete gastric juice, and every 60- 100g of wine can increase gastric juice secretion 120ml. Tannin in wine can increase the contraction of smooth muscle fibers in intestinal muscle system and regulate the function of colon. Has certain curative effect on colitis. Sweet white wine contains sorbitol, which helps digestion and prevents constipation.
6, weight loss effect
Wine can lose weight. Every liter of dry wine contains 525 calories, which is only 65,438+0/65,438+05 of the average daily calorie required by human body. After drinking wine, it can be directly absorbed and digested by the human body, and it will be completely consumed within 4 hours without gaining weight. Therefore, people who often drink dry wine can not only supplement the water and various nutrients needed by the human body, but also help to lose weight.
7, diuretic effect
Some liquors contain high contents of potassium tartrate, potassium sulfate and potassium oxide, which has diuretic effect, can prevent edema and maintain acid-base balance in the body.
8, sterilization effect
The bactericidal effect of wine has long been recognized. For example, colds are common and frequently-occurring diseases, and antibacterial substances in wine can inhibit influenza viruses. The traditional method is to drink a glass of hot wine or a glass of red wine after heating, add an egg and stir, that is, stop heating and drink after cooling slightly. Studies show that the bactericidal effect of wine is because it contains antibacterial and bactericidal substances.
Second, the auxiliary therapeutic effect of wine on some diseases
1, alcohol and the prevention and treatment of cardiovascular diseases
Procyanidins in wine can stably form collagen fibers of various membranes, inhibit histidine decarboxylase, avoid producing too much histidine, reduce the permeability of blood vessel wall and prevent arteriosclerosis. In addition, the risk of death from proanthocyanidin infarction. According to the statistics of the American Medical Research Association, French and Italians who like to drink low-alcohol wine have the lowest death rate from heart disease, while Americans and Finns who drink more and drink less have a high death rate from heart disease.
2. The preventive and therapeutic effects of wine on cerebral thrombosis
Wine contains resveratrol, which is a plant antitoxin and can inhibit platelet aggregation. Veratrum in wine exists in grape skin and is a taxonomic glycoside. It contains about 1 μ g/L in red wine, but only 0.2 μ g in white wine. Experiments show that even if red wine is diluted 1000 times, it can still effectively inhibit platelet aggregation, with an inhibition rate of 42%, which can reduce the occurrence of cerebral thrombosis.
3. Wine can prevent and treat kidney calculi.
German scientists found in their research that moderate drinking of wine can prevent kidney calculi. Recently, medical scientists from the Medical Research Institute of Munich University pointed out that the traditional view that drinking more drinks can prevent kidney calculi is unscientific and incomplete, and the most important thing is to look at what kind of drinks to drink. Through clinical observation of 45,000 healthy people and patients, the researchers confirmed that people who drink regularly and moderately are unlikely to suffer from kidney calculi's disease. Researchers found that people who drink different drinks in moderation have different risks of kidney calculi. People who drink a quarter liter of coffee every day have a 65,438+00% lower risk of kidney calculi than people who don't have this habit. Drinking black tea often is low14%; People who drink regularly have the least chance of developing kidney calculi, and their risk is 36% lower than those who are not used to drinking.
4. Alcohol can prevent breast cancer.
The latest experimental results show that wine has a strong inhibitory effect on cancer by feeding mice that induce cancer. Researchers at Illinois Pharmaceutical University chose mulberry, peanut and grape skin as the most effective anticancer agents. American scientists have recently discovered that wine contains a chemical that can prevent breast cancer. Williams told a news conference in Washington that they found a substance in red wine and white wine that can prevent breast cancer. This substance has this effect because it can resist estrogen, which is associated with breast cancer.
5. Alcohol can inhibit fat absorption.
Japanese scientists found that red wine can inhibit fat absorption, and some mice did experiments. After drinking wine for a period of time, mice found that the absorption rate of fat in the intestine slowed down, and the same conclusion was reached in clinical trials on people.
6, red wine to prevent retinal degeneration.
Harvard University found that red wine can prevent macular degeneration. Macular degeneration is caused by the free of harmful oxygen molecules, which damages the macula in the body. Wine, especially red wine, contains resveratrol, which can eliminate oxygen free radicals and protect eyesight from it. Experiments have confirmed that people who often drink a small amount of red wine are 20% less likely to suffer from macular degeneration than those who don't drink.
7. Alcohol helps to improve memory.
The experimental results published by scientists show that moderate drinking helps to improve brain memory and learning ability. After a lot of experiments, two doctors from Milan University found that drinking wine in moderation can promote the brain to produce a certain amount of chemicals, which can promote the production of an enzyme related to nerve cell memory. According to the measurement, compared with non-drinkers, the production of this enzyme after drinking alcohol enhances the memory and learning ability of the brain. Another doctor found that obese patients who drink alcohol properly during weight loss will maintain vigorous energy and will not be depressed because of dieting, which will lead to memory loss.
8. Alcohol can prevent colds.
So far, there is no good strategy for influenza in the world, because the influenza virus is resistant to most drugs. But the study found that people who drink wine often seldom catch a cold. This phenomenon attracted attention, and they added red liquor and grape juice to the virus culture solution for experiments. The results showed that common cold viruses such as herpes simplex virus and coxsackie virus would lose their vitality in wine and juice, and the juice extracted from grape skin was the best. Scientists believe that this is because grapes contain "phenol" compounds, which can form a thin film on the surface of the virus, making it difficult for it to enter human cells, thus achieving the effect of preventing and treating colds. Because "phenol" mainly exists in grape skins, drinking hot red wine when you have a cold can alleviate and prevent colds.
The above facts show that it is no exaggeration to call wine "the oldest drink and the most important medicine that has never been used in the whole world history".
Third, other benefits of wine supplement.
A large number of studies have confirmed that drinking a proper amount of wine every day (commonly known as "red wine") is beneficial to human health, especially for heart disease known as "life killer".
Obesity, blood vessel blockage and organ function decline are all due to excessive intake of acidic substances, so it is very necessary to keep the body in a weak alkaline state for human health. Wine is one of the rare alkaline drinks in alcoholic beverages. When eating acidic foods such as big fish and big meat, drinking a proper amount of wine is very helpful to neutralize the pH of the human body.
The chief culprit of cardiovascular diseases is the high content of cholesterol and blood lipids in the blood. The content of polyphenols in wine is high-"resveratrol" can reduce the content of bad cholesterol and blood lipid in blood, thus alleviating atherosclerosis and heart disease. In addition, it also contains super antioxidants, which can remove free radicals produced in the body, protect cells and organs from oxidation, and restore skin whitening and luster, so wine is known as "milk for the elderly".
It is France that has benefited the most from drinking wine. There is no profound reason why French people drink wine and China people drink tea. According to a survey, 95 out of every 65,438+10,000 middle-aged men in France die of heart disease every year, while as many as 256 in the United States. The French drink the most in the world. Excessive drinking and high-calorie food will not increase the probability of heart disease in French people, which is called "French paradox".
The alcohol content of wine is generally 12 ~ 16, which is rich in vitamins and contains trace elements such as manganese, zinc, molybdenum and selenium. But wine is wine after all, as the saying goes, "water can carry a boat, but it can also overturn it." Although the degree is not as high as that of spirits, if you drink too much for a long time or drink too much, it will also lead to the body absorbing too much alcohol. When the liver is overwhelmed, the toxins that can't be discharged will accumulate day by day, which will make other organs of the body decline and even lead to cirrhosis.
Therefore, drinking must be moderate. Generally speaking, it is advisable for middle-aged men to drink 100~ 150 ml (about 2~3 ounces) every day, and women can reduce it appropriately. In addition, drinking on an empty stomach should be avoided, and it is best to drink with food and beverage. This can increase appetite, help digestion and reduce the absorption of alcohol; And that absorption speed will be slow, which is beneficial to the elimination of active oxygen in wine.
The disadvantages of drinking red wine:
In fact, drinking red wine has no special benefits. Although it is helpful to dilate blood vessels, it should be moderate. If it is very big, it is very bad for the heart and will lead to alcoholic myocarditis. In fact, alcohol is absolutely bad for the brain, liver and pancreas. Therefore, it is a bad idea to protect the heart with wine, but it can really reduce the incidence of heart disease, because antioxidants in red wine can prevent cholesterol oxidation and arteriosclerosis. When platelets in the body meet these lumps, they will think that this is the injured area, which will cause coagulation reaction. This process will form a large blockage in blood vessels, which will cause a stroke or myocardial infarction. Therefore, good health or more exercise, not overeating, balanced vegetables and fruits, is most beneficial to the body.
Don't eat with red wine
Coffee, seaweed, tea, black fungus and red wine will reduce the body's absorption of iron; Pig liver+red wine is not conducive to the absorption of iron by human body.
