Grapes are native to Asia Minor in Asia Minor Asia. In the early Mesopotamian civilization around 4000 BC, humans were able to make wine. Nowadays, wine has become a common drink on people's table and is also known as “always wineâ€. In 1992, in the French TV broadcast of the Columbia Broadcasting Co., "The Mystery of France," the French loved high-fat, high-sugar food, and the incidence of heart disease was the lowest in the world. It was attributed to the French people's love for wine. Does drinking red wine really prevent heart disease?
The famous "French paradox" gave rise to the concept of "drinking red wine to reduce heart disease". However, it was later found that the series of studies that substantiated this conclusion had falsified conditions, and that red wine had also become an "ecstatic star" in alcoholic beverages.
Resveratrol has a magical effect
Red wine has a beautiful color, unique fragrance, 1 to 5 grams of phenolic compounds per liter of red wine, polyphenols in red wine (gallic acid, catechins, quercetin, procyanidins, resveratrol) Can inhibit the oxidation of low-density lipoprotein, inhibit platelet aggregation, thereby preventing atherosclerosis, reduce the incidence of cardiovascular disease and mortality, the most important element of which is resveratrol.
Resveratrol is found in 72 plant species such as grape skins, peanuts, and mulberries, and is the highest content in grapes. It is a phytoalexin produced by vines to resist mold invasion. Resveratrol is insoluble in water and cannot be absorbed by the body, but it is soluble in alcohol. Resveratrol has anti-platelet aggregation, regulates lipid metabolism, protects the heart, and regulates estrogen.
Drinking red wine does not help the heart
An animal experiment showed that when resveratrol is used in a dose of 250-500 mg, it can prevent arteriosclerosis in mice. Converted to the human body, the intake of resveratrol per day is at least 2g. The content of resveratrol in red wine is between 1~16.3mg/L, while the capacity of a bottle of wine is 750ml, so if you want to reach an effective dose, you need to drink 120~160 bottles!
Another study suggests that the bioavailability of resveratrol in the human body is extremely low. A person needs to drink at least 60 L of red wine each day to reach an effective dose. In other words, even if you go for a swim in a red wine bath every day, you cannot bring considerable heart benefits.
French public opinion is due to the structure of the Mediterranean diet
The emergence of "French Paradox" cannot be ignored: The French region is dominated by Mediterranean diets such as fruits, vegetables, grains, beans, and olive oil. The Mediterranean diet also emphasizes: the principle of proper quantity and balance, a healthy lifestyle, an optimistic attitude towards life, and adherence to moderate exercise. This is the key factor in their cardiovascular health.
The benefits of resveratrol are like a "magical bullet" that has received widespread attention from scientists. However, clinical trials have shown that this polyphenol does not have a substantial effect on health status and reduce the risk of death. Based on the deficiencies of epidemiology and in vivo experiments, the study of "red wine to prevent heart disease" is still in the exploratory stage of human age, individual differences, metabolism, microbiota and wine complex chemical reactions in the production process.
At present, animal experiments use high concentrations of resveratrol. However, if we take the effect of resveratrol by direct drinking of wine, it is not known. Moreover, studies have shown that taking a very low dose of resveratrol supplements may cause adverse reactions such as diarrhea, muscle cramps, and loss of appetite.
Try to drink as little or as little as possible
It is said that the amount of alcohol should be appropriate. In the 2016 drinking guidelines launched by the UK Department of Health, it is recommended that you do not use excessive amounts of alcohol at one time, and that heavy drinking increases the risk of chronic diseases. In order to minimize health risks, the amount of alcohol consumed by the public should not exceed 14 units per week, and the 14 units of alcohol should be averaged in 3 days as much as possible.
Some people may say that foreign standards may not be suitable for domestic consumption. In 2016, the Chinese Dietary Guidelines also gave recommendations: Adults and women should not exceed 25 g and 15 g of alcohol a day.
However, this "right amount" can still lead to a significant increase in the risk of many diseases. For example, the risk of oral and pharyngeal cancers may increase by 82%, the risk of esophageal cancer by 39%, the risk of laryngeal cancer by 43%, the risk of breast cancer by 25%, the risk of primary hypertension by 43%, and the risk of chronic pancreatitis 34% increased the risk of cirrhosis by 1.9 times.
Other risks such as colon cancer, rectal cancer, and liver cancer also increased slightly. As long as drinking alcohol will increase the incidence of breast cancer and atrial fibrillation. There is no absolute safety for drinking and it is recommended that you drink as little or even as little as possible for good health.
In addition, drinking can lead to more calories, often with meat when drinking, plus 100g of red wine to produce 74kcal of energy. If you accidentally take too much. If you can't control it, it will do more harm than good.
