WOMEN who eat about three servings of fish per week have a somewhat lower chance of having colon polyps, which can develop into cancer, than women who eat less than a serving a week, according to a US study.
Though the research, which covered more than 5,000 people and appeared in The American Journal of Clinical Nutrition, didn't prove that seafood protects against polyps, earlier experiments in animals have showed that the omega-3 fatty acids in fish can reduce the risk of colorectal cancer.
About 140,000 new cases of colon and rectal cancer are diagnosed each year in the United States, according to the American Cancer Society.
The idea that 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 growth of polyps.
Eating Omega-3 fatty acids keeps down the level of Omega-6 acids, which in turn cuts levels of the hormone, said Harvey Murff, a professor at Vanderbilt University in Nashville, Tennessee who led the study. He noted that the women in the study who ate more fish had lower levels of the hormone.
