Young women often drink green tea can effectively prevent gastric ulcer. Catechins in green tea can inhibit or even kill Helicobacter pylori, which causes gastric ulcer and duodenal ulcer. The researchers found that in more than 10 experimental samples, 2% of catechins in green tea can inhibit Helicobacter pylori. If the catechins content is increased to 4%, it can kill Helicobacter pylori.
A study by the University of Hong Kong found that drinking three small cups of green tea a day, especially Longjing tea, can effectively inhibit Helicobacter pylori and reduce the risk of gastric ulcer.
This study from the Department of pharmacology, School of medicine, HKU found that catechins in green tea can inhibit or even kill Helicobacter pylori, which causes gastric and duodenal ulcers. The researchers found that in more than 10 experimental samples, 2% of catechins in green tea can inhibit Helicobacter pylori. If the catechins content is increased to 4%, it can kill Helicobacter pylori.
Professor Gu Yongliang, who is in charge of the research, explained that Helicobacter pylori has a strong growth ability, can release an enzyme, and then produce a large amount of alkaline amonia, forming a protective film. No matter how acidic the gastric juice is, it can not be killed. However, catechins can prevent Helicobacter pylori from producing amonia and weaken its activity.
Another survey by the Department of pharmacology of HKU also found that the rate of Helicobacter pylori found in the stomach of people who have the habit of drinking tea is relatively low. The results of this study are further confirmed.
Gu Yongliang pointed out that the catechin content of green tea was higher than that of black tea, and Longjing tea had the highest catechin content, followed by Japanese green tea and jasmine tea.
However, traditional Chinese medicine believes that people with deficient cold constitution should not drink too much green tea. If they have stomachache and no appetite after drinking tea, it is better to drink less or eat something before drinking.
After reading the above content, you should have some understanding of the problem that young women often drink green tea can effectively prevent gastric ulcer. Today we will introduce here.
