Professor Morton of the University of Miami in the United States conducted a field study on people who often drink a lot of tea and found that certain people who drink tea for a long time have a significantly higher incidence of gastric cancer. The reason for the high incidence of gastric cancer in these areas is that long-term large-scale drinking contains more tannin Indian tea. Chunmee Tea contains less tannic acid and does not have the disadvantages of Indian tea. Therefore, Professor Morton recommends drinking Chinese tea. A professor at National Taiwan University once did an experiment in which tea was ground into powder and mixed with feed to feed mice inoculated with cancer cells. After 3 weeks, cancer cells were significantly suppressed or even reduced. Therefore, he believes that regular tea can prevent cancer. Current research results believe that the main anti-cancer substance in tea is tea polyphenols, which can significantly inhibit cell mutations, which can sometimes cause cancer. In addition, tea can block the synthesis of nitroso compounds and also has a certain anti-cancer effect. Green Tea Factory believes that some studies also show that tea can reduce radiation damage and have anti-radiation effects. Tea is rich in vitamin c and vitamin e, and it also has anti-cancer effects. Therefore, drinking tea regularly is of great benefit to patients with lung cancer. Among them, delicate green tea has the best anti-cancer effect.
