Report: A group of local scientists has discovered that green tea, which is widely popular among South Koreans, helps lower the risk of getting colon cancer.
The team, led by Professor Lee Dong-ho of Seoul National University Bundang Hospital, carried out a clinical trial with 143 patients who underwent complete removal of colorectal adenomas, or precursor lesions of colon cancer.
The team found that the incidence of adenoma stood at 23 percent in case of 72 patients who consumed zero-point-nine grams of green tea extract every day for a year. That figure was nearly half compared to the incidence rate of patients who didn’t consume green tea extract.
That means drinking four cups of green tea every day could lower the risk of getting colon cancer by more than 40 percent.
The team said it found that catechin, a major component of green tea extract that has an anticancer effect, repressed the incidence of tumors.
The team expects its study will open new possibilities in utilizing green tea in terms of preventing and treating colon cancer.
The latest research results were published in the latest edition of Clinical Nutrition, the official journal of the European Society for Clinical Nutrition and Metabolism.
