This article has been read by more than 100000 people on a public account. This seemingly popular science article lists nine benefits of coffee, almost to the point of "magic medicine". Nanjing medical experts said in an interview with the Yangzi Evening News that the benefits of coffee listed in the article are not accurate.

It is rumored that drinking coffee has "9 magic effects" in moments.

The article, which went viral on Wechat yesterday, lists nine benefits of coffee. After reading the unknown efficacy of these nine bars of coffee, do you also want to serve a cup of coffee immediately and drink it and feel refreshed from now on?

1. Coffee can accelerate the metabolism of the skin and dilute the dark circles under the eyes caused by poor circulation. It has the effect of anti-oxidation, which can keep skin cells full of vitality and prevent cell oxidation, thus anti-aging.

2. anti-cancer and anti-cancer. Caffeine can also inhibit tumor growth. If women could drink 4-6 cups of coffee a day, the incidence of breast cancer would be reduced by 25% and 70%.

3. Nourish the stomach and aid digestion. People who love meat had better have a cup of coffee after dinner, which has a good effect on relieving grease and aiding digestion.

4. Protect the liver. Coffee is rich in polyphenols that also protect the liver. Patients with hepatitis are advised to drink some coffee every day, which is good for the repair of liver cells. Drinking coffee can also help people with heavy drinking, overweight, diabetes or iron overload reduce the risk of liver disease, but there is no evidence that coffee and tea can reduce the risk of chronic liver disease from fatty liver or viral hepatitis.

5. Prevent radiation injury. Studies have clearly shown that coffee helps prevent radiation damage.

6. relieve the soreness of exercise. Drinking coffee can help people relieve muscle pain caused by excessive exercise, but it often works only for people who don't drink coffee very often, according to a study.

7. Relieving alcohol. Drinking the right amount of coffee after drinking can quickly oxidize acetaldehyde converted from alcohol, decompose it into water and carbon dioxide and discharge it out of the body.

8. Prevent gallstones. Caffeinated coffee can stimulate gallbladder contraction and reduce cholesterol, which is easy to form gallstones in bile.

9. Prevent depression. People who drink coffee regularly will feel less happy and irritable, and their mood will be improved.

Drinking an appropriate amount of black coffee has a certain health effect.

"if it is black coffee with nothing, it has a certain health effect." Li Qun, director of the Nutrition Department of Jiangsu Provincial people's Hospital, said, "it has a relatively definite effect, for example, coffee contains a certain amount of caffeine, which not only has a protective effect on cardiovascular system, but also has a certain antioxidant capacity, so if you drink black coffee in the right amount, it can really play a role in cardiovascular protection, beauty and beauty, and even weight loss." But whether even black coffee can be as omnipotent as Wechat says, more scientific experiments are needed to prove it.

The above is only an ideal state. In daily life, many people are not used to drinking bitter coffee. They have to add sugar and milk to the coffee before they feel that the entrance is smoother. However, after this treatment of coffee, coffee "turned" into a problem drink. "adding sugar increases energy intake, and adding milk is OK, but many coffee shops in life add plant fat powder or cream, which are trans fatty acids, which will certainly endanger cardiovascular and cerebrovascular health if consumed for a long time." In daily life, many white-collar workers like to order lattes, cappuccinos, caramel macchiato, etc., but also have the problem of excessive energy.

Can coffee fight cancer? The story is unreliable.

Can drinking coffee fight cancer? Some nutrition experts say it is not reliable. Experts say that the argument that coffee is carcinogenic or anticancer is also inconsistent because acrylamide is detected in instant coffee, which may lead to human cancer and has a potential carcinogenic risk; anticancer theory is because coffee contains a certain amount of caffeine, caffeine has a certain anticancer effect. There is a saying in the nutrition circle: "there is no bad food, only unreasonable collocation", "there is no beauty or evil, and mistakes are disasters." If you rely on a single food to fight cancer, this idea and practice is impractical.

Whether coffee is healthy or not, in addition to the type of coffee, how much you drink and who drinks it are all influencing factors. In the reporter's interview, no doctor advised the public to drink more coffee. Doctors also disapprove of Wechat's suggestion that women "drink more than three cups of caffeinated coffee a day" to prevent breast cancer. In addition to the reasons for excessive energy, doctors do not advise citizens to drink more coffee, but also because coffee leads to calcium loss and other adverse factors.

Director Li Qun told reporters that coffee itself has a diuretic effect, which will lead to the loss of calcium in the body with the urine, increasing the risk of osteoporosis. In addition, the polyphenols in coffee will also form insoluble salts with iron and inhibit the absorption of iron. For women, drinking too much coffee can lead to iron deficiency anemia. In addition, compared with tea, coffee is more addictive and more likely to be dependent.
