Consumption of trans fatty acids from partially hydrogenated
oils is associated with the risk of CAD in observational
studies. Unfortunately, the price, mouth-feel, and stability of
such hydrogenated oils make them a favorite of manufacturers
of fast foods (94). Palm oil is an acceptable alternative for the
industry, and, in terms of the effect on total:HDL cholesterol,
palm oil is still better than the partially hydrogenated vegetable
oils used in the food service industry. However, unhydrogenated
vegetable oils produce a much more favorable lipid
profile than do either palm oil or hydrogenated oils, and they
should be preferred.
