Now let's talk about red wine. Its sweet and sour taste, attractive aroma and color, elegance and taste are secondary. What we value most is the health benefits of red wine.

Wine always gives people the impression that it is harmful to health, but red wine is an exception. We are used to seeing red wine as a healthy drink.

Red wine was associated with health at the end of the twentieth century, which was also attributed to the famous "French paradox".

The French diet is not low in fat, high in calories and high in cholesterol, but their probability of cardiovascular disease is very low.

1992 in American TV programs, the reason of "French paradox" is attributed to the habit of French people drinking red wine.

In 2006, the research team of Harvard University found that resveratrol in red wine can activate longevity protein and increase the life span of experimental mice.

From then on, it is logical to form an idea about health:

Reduce cardiovascular diseases and prolong life >:>& gt Drink red wine >>& gt Red wine contains resveratrol.

After the publicity, the whole world set off an upsurge of red wine health preservation. According to statistics, since 20 14, China has surpassed France to become the largest consumer of red wine in the world, which shows that more and more people in China believe that drinking red wine can prolong life.

Resveratrol has become a hot spot in the research field, and there are thousands of papers on resveratrol at home and abroad. It has been endowed with more and more health care functions, such as scavenging free radicals, resisting oxidation, protecting cardiovascular system, resisting cancer, regulating blood sugar, delaying aging and reducing the risk of Alzheimer's disease. ...

Resveratrol exists in Chinese medicinal materials such as Polygonum cuspidatum and Polygonum Multiflori Radix, as well as in daily foods such as grapes, peanuts, blueberries and mulberries.

When plants are attacked by bacteria and fungi, the content of resveratrol will increase, so it is regarded as plant antitoxin and plant defense weapon.

Moreover, some scholars have suggested that although resveratrol exists in plant foods such as grapes and peanuts, it is difficult for the human body to absorb it because it is insoluble in water, and it is of little use to eat it directly. Red wine is different. Resveratrol in grape skin has been dissolved in alcohol during the brewing process, which is more conducive to absorption. This statement once again provides proof for the health of red wine.

Everything is going well, but in recent years, things have taken a surprising turn and resveratrol has begun to be questioned.

1, well-known scholars' fraud was made public.

Professor Dipak K. Das, Director of Cardiovascular Research Center of Connecticut State University, USA, is an authority on red wine and resveratrol. He has published 1 17 papers on resveratrol.

However, on 20 12, Kangzhou University filed a complaint against Professor Das and dismissed him because his thesis was false. He falsified a large number of research data, and many research papers were fraudulent, and most of these papers were related to resveratrol.

Some people suspect that there is an interest relationship between Professor Darth and the wine merchants, which makes everyone begin to re-examine the efficacy of resveratrol.

2. Questioning the experimental design.

Some people question that the number of samples used in the experiment is too small, the experimental results are accidental, and the results of many animal experiments cannot be repeated.

Some people say that the experiments studied at present are all in vitro experiments and animal experiments, and the effects on human body cannot be directly inferred from these results.

Some people think that the dose of resveratrol fed to mice in the experiment is very large, while the content of resveratrol in red wine is very low, which can not achieve the same effect.

3. Other unfavorable research results have appeared.

The researchers chose two Italian towns rich in red wine and conducted a nine-year health survey on 783 elderly people who had the habit of drinking red wine. Record the content of resveratrol in their daily diet and urine.

Nine years later, 34 of these old people got cancer, 174 got heart disease and 250 died. This ratio is basically the same as that of people who don't drink red wine. The results show that resveratrol's prevention of cancer and cardiovascular diseases is not as magical as everyone thinks.

In human studies, people who consume more than 0.5 grams of resveratrol every day will have adverse reactions and even risk causing kidney disease. It shows that the intake of resveratrol is not as much as possible. Fortunately, the content of resveratrol in red wine is very low, so there is no need to worry about safety. However, it is better not to eat resveratrol as a health care product.

At present, there are still great differences about the statement of red wine health preservation.

After all, red wine contains not only resveratrol, but also tannins and anthocyanins. A variety of phenols are worthy of further study by researchers. It is too arbitrary to directly deny red wine now.

However, red wine is not as magical as everyone thinks, and it is also wine itself. Drinking too much is definitely harmful to your health.

Personally, if you like red wine, it is good to drink a small amount; If you don't like it at first, just for health, there is really no need to drink it.
