Expensive wine ages well, which means it will taste better after being kept for many years.

Is it bad? You can drink it within 1-2 years after brewing, and The taste is relatively simple and has no depth

If it is domestically produced, buy Great Wall dry red, which is more cost-effective

Take imported red wine as an example. The supermarket price is around 300, which is considered a mid-range wine for ordinary people. That’s okay. For around 100, it is better to buy domestic wine. Is it cheap? 40-60 per bottle. The import price is RMB 5.

Nutritional value

Heat energy: The heat value of dry red wine is equivalent to the heat value of milk. The caloric value of one liter of dry red wine at 10 degrees is 560 kcal, which is mainly the heat energy provided when alcohol is oxidized. In the case of sweet wine, the sugar content is also the main source of heat energy.

Amino acids: There are 8 kinds of amino acids that the human body cannot synthesize by itself and are called the human body's "essential amino acids". Both grapes and wine contain these 8 "essential amino acids". This is unmatched by any fruit or drink, so people call wine a "natural amino acid food" and has been approved by the United Nations Health Food Organization as the healthiest and most hygienic food. In red wine, the content of these 8 amino acids is very close to the content in human blood. Regular drinking in moderation can effectively supplement the needs of the human body.

Minerals: The minerals contained in wine include "trace elements" (such as iron, zinc, copper, manganese, iodine, chromium, etc.) and calcium, magnesium, phosphorus, etc., which are also needed by the human body. of nutrients.

Others: Wine also contains a variety of B vitamins, vitamin C, vitamin P and other nutrients needed by the human body.

Health care effects

Appetite, strengthen the spleen, help digestion, and prevent constipation

All the natural acidic substances in the grape itself are dissolved in the wine, and its acidity is close to gastric acid ( pH 2~2.5). Therefore, wine is a great food accompaniment and can help digest and absorb protein. In addition, wine contains sorbitol, which is beneficial to the secretion of bile and pancreatic juice. It not only enhances the digestion and absorption of food in the gastrointestinal tract, but also adjusts the function of the colon, which has a certain effect on colitis. Therefore, drinking wine before meals, especially for middle-aged and elderly people, can aid digestion and is very beneficial to the body. At the same time, the tannins in wine can increase the contractility of intestinal muscle fibers, and the potassium tartrate and potassium sulfate can be diuretic and prevent edema.

Prevent and treat cardiovascular disease

Wine contains more anthocyanins, proanthocyanidins, tannins and other substances, which have obvious effects of dilating blood vessels and enhancing vascular permeability. effect. These substances are more abundant in red wine than in white wine. Modern medicine points out that the main culprit of cardiovascular disease is high levels of cholesterol and blood lipids in the blood. The human body's high-density lipoprotein can transport cholesterol in blood vessels to the liver, where it is converted into hormones useful to the human body, and the excess is excreted in the stool. Moderate drinking of wine, especially red wine, can increase and reduce the levels of high-density lipoprotein in the body and blood cholesterol and blood lipids, thereby preventing atherosclerosis and heart disease.

For example, in the French diet, their representative foods such as whipped cream, butter, cheese, etc. contain a large amount of animal fat. The French consume almost four times as much saturated fatty acids as Americans and British people, but strangely, the French are only one-third as likely to suffer from atherosclerotic heart disease as Americans and British people. Many experts believe that this strange and counterintuitive phenomenon - the "French Paradox" - is related to the French people's habit of drinking wine with every meal, especially red wine.

Prevent Stroke

Studies have shown that red wine is an incredible anticoagulant. Drinking a little red wine regularly can dilute the blood and prevent the formation of blood clots in blood vessels, thereby preventing the occurrence or attack of cardiovascular and cerebrovascular diseases. French scientists confirmed in a study that red wine can not only inhibit platelet aggregation to prevent thrombosis, but also increase the level of high-density lipoprotein. Therefore, researchers claim that red wine’s anticoagulant effect on cardiovascular and cerebrovascular protection is unique. New evidence suggests wine drinkers are less likely to have a stroke. A 16-year study of more than 10,000 people found that people who drank 1 to 6 glasses of red wine per week had a lower incidence of stroke than those who drank nothing or rarely drank. 34%. Therefore, Dr. John Foltz, a cardiovascular disease expert at the University of Wisconsin Medical School, once said: "Drinking red wine can produce an anti-thrombotic effect in human blood, which is better than taking aspirin, because taking aspirin Lin can cause stomach upset."

Anti-aging

Red wine is a powerful exogenous antioxidant. Free radicals are related to human disease and aging. Antioxidants prevent free radicals from attacking human cells by scavenging them. The human body produces effective endogenous antioxidants, but the body also needs exogenous antioxidants to supplement this defense system. Red wine is one of six known powerful exogenous antioxidants (special fresh olive oil, tea, fruits, vegetables, red wine, vitamin antioxidants).

The many antioxidants in red wine can act on reactive oxygen groups in a variety of ways. The simplest way is to remove reactive substances. Salicylic acid, benzoic acid and their metabolites in wine belong to the class of antioxidants called reactive oxygen species scavengers. Another important way to eliminate reactive oxygen species is for antioxidants to provide a hydrogen ion to them, which combines with oxygen free radicals to remove them. Catechins, anthocyanins, etc. in wine can scavenge oxygen free radicals.

Rich in resveratrol

Scientists have isolated resveratrol, the active component of red wine’s health care function. Its chemical name is trihydroxystilbene. It was discovered by American scholars A polyphenol substance first reported in 1992, it is a phytoalexin produced by grapes under ultraviolet irradiation. Scholars at home and abroad generally believe that resveratrol has extremely strong antioxidant properties. It can effectively eliminate free radicals, inhibit various oxidative reactions that cause atherosclerosis and thrombosis, promote blood circulation and reduce The deposits on blood vessel walls are particularly effective in preventing heart disease and stroke. As a health drink for middle-aged and elderly people, red wine can prevent Alzheimer's disease. What is even more encouraging is that resveratrol has certain anti-cancer activity. Its antioxidant and anti-mutagenic functions can block the three stages of cancer (initiation, development, and spread). .

Precautions during drinking

A large amount of research data has reached the same conclusion: the key to achieving good health effects of red wine is moderate amount and regularity. Most experts recommend drinking between 50 ml and 200 ml of red wine per day, and the choice within this range can vary from person to person. As someone pointed out, wine is a double-edged sword, and red wine is no exception. Moderate and regular drinking has good health effects, but large or excessive amounts are counterproductive. Experts also point out that people with liver disease, women who are prone to breast cancer, or pregnant women should not drink alcohol (including red wine).
