Coffee may cut risk of colon cancer
A cup or two of coffee a day may help lower the risk of developing colon cancer, according to the new study at the University of Southern California.
Researchers looked at 8,500 people in Israel and about 5,000 of those people had colorectal cancer. On average, the people in the study drank about two cups of coffee a day. Researchers found that coffee drinkers reduced their risk for developing colorectal cancer by 30 percent, compared to people who didn’t drink coffee.
They also found that the more coffee people drank, the lower their risk for developing colon cancer. People who drank two to two-and-a-half cups of coffee had a 44 percent reduced risk and those who drank more than two-and-a-half cups had a 59 percent reduced risk.
Researchers hypothesize that drinking coffee lowers colorectal cancer risk because it speeds up the passage of substances through the colon. This means the tissue has less time to be exposed to cancer-causing agents. Or, it may be that coffee affects the composition of microbes in the gut, or possibly that compounds in coffee have properties that help prevent cancer.
