These folks want to ban trans fats. I understand the immediacy of the situation, we are facing an epidemic of obesity and heart disease in America. But I'm not convinced that we should ban hydrogenated oils.
This is actually a little more complicated than you might think. The process of creating trans fats causes the removal of Omega 3 from fatty acids. Susan Allport points out that it could be this lack of Omega 3 that is truly the problem. She agrees that trans fats are bad -- but the real culprit in her eyes is the lack of Omega 3 relative to Omega 6. She points out that you could give up trans fats completely and still not be healthy, if you did not get your Omega 3s.
Susan also makes a good point about fish oil: It is the Omega 3 in fish that makes them such healthy meals for we fish eaters. Even beef could be high in Omega 3 if those cows were eating the right stuff!
