People who drink coffee and soda are not more at risk of developing colon cancer than those who do not, according to a recent study.
The research, conducted at the Harvard School of Public Health and published in the Journal of the National Cancer Institute, looked at 13 previous studies on the disease conducted in the US and Europe.
Some of these studies have previously suggested that coffee and tea could increase the risk, and some have claimed it could be lowered. Science Daily points out that tea contains anti-oxidants that could serve to prevent cancer but also has polyamines, which theoretically promote cancer.
The new survey looked at 731,441, followed for up to 20 years, 5,604 of which developed colon cancer. Insight into their eating and drinking habits found that coffee lovers – even those who drank up to 6 cups a day – were not more likely to develop the illness. This also applied to those who drank large amounts of soda.
“Drinking coffee, even more than six cups a day, was not associated with risk of colon cancer,” confirmed researcher Dr. Xuehong Zhang of the Harvard School of Public Health.
“The relationship between tea and colon cancer is unclear for the time being,” Dr Zhang added, however.
