Large study associates increased tea intake with protection against digestive system cancers.
Findings from the Shanghai Women's Health Study reported in the American Journal of Clinical Nutrition reveal a protective effect for tea drinking against cancers of the stomach, esophagus, and colon in middle-aged Chinese women.*
Researchers analyzed data from 69,310 women who were between the ages of 40 and 70 years upon recruitment in 2000. Interviews and questionnaires completed upon enrollment provided information on tea intake. The participants were followed for an average of 12 years, during which three follow-up surveys were conducted. Over the follow-up period, 1,255 digestive system cancers occurred.
Among regular tea drinkers, categorized as those who consumed tea three or more times per week over a period of no less than six months, a 14% lower risk of all digestive system cancers was observed in comparison with those who did not consume tea.
Editor's Note: When digestive cancers were analyzed according to type, the protective effect of tea was associated mainly with colorectal and stomach/esophageal cancers, for which there was a 27% lower age-adjusted risk observed among regular tea drinkers compared to non-drinkers.
