Excess omega-6 oil consumption leads to ulcerative colitis

People who were the heaviest consumers of omega-6 PUFA were more than twice as likely to develop ulcerative colitis as those who consumed the least, according to a study that appears in Gut. Researchers found that eating more eicosapentaenoic acid (EPA), an omega-3 fatty acid found in fish and fish oils, was associated with a lower risk of the disease. While people need a certain amount of omega-6 to survive, excess amounts are taken up into the lining of the colon, and if they're released, they can promote inflammation. Omega-3 fatty acid does the opposite.

The analysis included 203,193 men and women 30 to 74 years old with follow-up which ranged from about 2 to 11 years.

Steve - for those following this blog, these results should come as no surprise.
