NEW YORK (Reuters Health) – Women who eat about three servings of fish per week have a somewhat lower chance of having polyps found during a routine colonoscopy than women who eat just one serving every two weeks, according to a new study.
The research doesn't prove that seafood protects against polyps, but it "does increase our confidence that something real is going on," said Dr. Edward Giovannucci, a professor at the Harvard School of Public Health in Boston, who was not involved in this study.
A polyp, also called an adenoma, is a mushroom-shaped tag of tissue that grows in the colon and can develop into colorectal cancer.
The idea researchers have been pursuing is that the omega-3 fats in fish might have an anti-inflammatory effect, similar to aspirin, that could prevent the development of polyps.
