Women who regularly drink green tea may have a lower risk of developing colon, stomach and throat cancers, according to a new study.
Green tea could lower the risk of cancer
Past studies have shown conflicting evidence on whether green tea reduces cancer risk. It is already known that green tea contains certain antioxidant chemicals which may ward off body cell damage that can lead to cancer and other diseases.
Now, a Canadian study has revealed that women who drank green tea at least three times a week were 14 per cent less likely to develop a cancer of the digestive system.
Researchers at the Vanderbilt University School of Medicine looked at data from a long-running health study of over 69,000 Chinese women who were middle-aged and older.
More than 19,000 of these women were considered regular tea-drinkers, who consumed it more than three times a week. Over an 11 year period, 1,255 women developed a digestive system cancer.
Women who said they’d regularly had green tea for at least 20 years were 27 per cent less likely than non-drinkers to develop any digestive system cancer.
Writing in the American Journal of Clinical Nutrition, the researchers also found that regular green-tea drinker were 29 per cent less likely to develop colorectal cancer. Study authors wrote:
“In this large study, tea consumption was associated with reduced risk of colorectal and stomach/esophageal cancers in Chinese women.”
However, green tea lovers are often found to be more health-conscious in general. Women in the study who drank a lot of green tea were younger, ate more fruits and vegetables, exercised more and had higher-income jobs.
The researchers tried to adjust for these differences, but the study still cannot prove cause and effect.
For the best cancer treatment that the UK has to offer look for a medical insurance policy with full cancer cover.
