Omega-3 Reduces Polyps Risk
April 29/Nutrition Action Healthletter -- An omega-3 fat found in fish oil reduces the risk of precancerous intestinal polyps in people who have a genetic predisposition to get polyps and colon cancer.
Researchers randomly assigned 55 people with familial adenomatous polyposis to take either 2g a day of EPA (eicosapentaenoic acid) or a placebo for six months.
The patients all had their colons removed years earlier, so the study looked at rectal polyps. The EPA was formulated as a free fatty acid so it would be absorbed quickly in the small intestine.
After six months, the patients who took EPA had 22% fewer polyps than the placebo takers, and the polyps they had were 30% smaller, according to Nicholas J. West, MBBS, of St. Mark's Hospital in London, and colleagues.
