Coffee may protect against colorectal cancer
Coffee contains several bioactive compounds doctors believe may protect against colorectal cancer. In this study, doctors compared coffee in the diets of 5,145 people with colorectal cancer to 4,097 healthy men and women. Participants reported how much coffee, espresso, instant, decaffeinated, and filtered coffee they drank. Doctors also considered family history of cancer, smoking, diet, and lifestyle choices including physical activity.

Men and women who consumed one to two servings—usually 8 ounces and 100 mg of caffeine—of coffee per day were 26 percent less likely to have developed colorectal cancer compared to those who drank less. Chances declined by 50 percent as people drank more than 2.5 servings per day. The type of coffee did not matter, including caffeinated and decaffeinated. Doctors believe that in addition to caffeine, other antioxidant compounds in coffee may have preventive effects, including polyphenols, and melanoidins that form during the roasting process.
