Trans fats aren't the worst of all possible evils

Last Updated Aug 2007



There is no more politically correct action than the elimination of trans fats from our food supply. Of course, without trans fats to make bad food taste better and last longer, our entire processed food industry would grind to a halt. The solution: A new type of synthetic fat consisting of interesterifed fat containing a lot of omega-6 fatty acids. Adding more pro-inflammatory omega-6 fats to the American diet is bad enough, but now a report comes in that these new interesterifed fats significantly increase blood glucose levels and lower HDL cholesterol levels. The mechanism is probably due to increased insulin resistance, which in turn will increase the levels of silent inflammation through the stimulation of the production of arachidonic acid. Talk about bad planning. Maybe trans fats aren't the worst of all possible evils. In fact, there is only one long- term human study on trans fats and heart disease. This was the Lyon Diet Heart Study done in France in the early 1990s. In this study, people who already had a heart attack were divided into two groups. One group got the American Heart Association diet rich in omega-6 fatty acids. The other group got a diet rich in trans fatty acids, but virtually devoid omega-6 fatty acids. After 3 1/2 years, those getting the trans fatty acids had 70 percent less mortality. This is not to say that trans fatty acids are good, but they appear to be a lot better than excess omega-6 fatty acids.

If you want processed foods to taste great, then maybe we should bring back lard since is virtually devoid of omega-6 fats and is the only saturated fat that doesn't raise total cholesterol levels.
