DRINK Water up your 8 glasses. You have one more reason to hit your water mark today: A recent study suggests it might lower your risk of colon cancer. Research conducted at the Fred Hutchinson Cancer Research Center, Seattle, added hearty support to previous studies that linked high consumption of fruits, vegetables, grains and low-fat dairy products to a reduced risk of colon cancer. But there was a new finding: When the data from the diet questionnaire completed by more than 400 middle-aged men and women with a history of colon cancer was compared with the same into gathered from their cancer free counterparts, another link appeared. Among women who drank more than five glasses of plain water a day, there were fewer cases of colon cancer. In fact, their risk was about half of what it was for women who drank fewer than two glasses a day. The same water intake afforded the men in the study only a suggestion of a reduced risk, a difference researchers say they can’t explain without further study.
