Drinking just one to two cups of coffee a day may reduce the risk of colon cancer, a new study suggests.
Researchers examined coffee consumption among nearly 8,500 people in Israel, including about 5,000 who had colorectal cancerand 3,500 who did not have cancer. On average, the people in the study drank just less than two cups of coffee per day.
Compared with the risk for people who drank less than one cup of coffee per day, the odds of developing colorectal cancer were 22 percent lower for people who drank one to two cups a day, 44 percent lower for those who drank two to two-and-a-half cups a day and 59 percent lower for those who drank more than two-and-a-half cups per day.
It’s been hypothesized that drinking coffee may lower colorectal-cancer risk by speeding up the passage of substances through the colon, meaning the tissue has less time to be exposed to potential cancer-causing agents. It’s also possible that drinking coffee affects the composition of microbes in the gut, or that compounds in coffee have cancer-preventing properties.
