The Finns are among the heaviest coffee drinkers in the world, with each person in Finland consuming more than twice as much coffee every year as the average European and nearly three times as much as Americans.
Yet, when more than 60,000 Finns were followed for more than 18 years, there was no difference in colon or rectal cancer between those who drank more than 10 cups a day and those who didn’t drink coffee at all.
Researchers tracked 60,041 Finnish men and women, aged 26 to 74 at enrollment, for an average of 18 years. None had cancer when they began the study. During that time there were 538 cases of colon cancer and 234 cases of rectal cancer.
Comparing the group who drank more than 10 cups of coffee a day and those who didn’t drink coffee at all, there was no differencel in risk for colon or rectal cancer for men, women, or men and women together.
Dr.Siamak Bidel and his team concluded,
In this study, we found no association between coffee consumption and the risk of colorectal, colon and rectal cancer.
