answer:Margerines that contain transfats, which most of them did before the latest information came out about those, are very bad for you, as is any tranfsat. “When margarine was first introduced to the marketplace, it was loaded with trans fats. The trans fats were created through hydrogenation – the very process used to solidify liquid vegetable oil into a spread. Just like saturated fats, trans fats increase LDL cholesterol (“bad” cholesterol) and lower HDL cholesterol (“good” cholesterol). In recent years, food manufacturers and the general public began to realize the negative health effects of trans fats. As a result, manufacturers have created non-hydrogenated margarine, which is now widely available. Non-hydrogenated margarine contains no trans fat, and it’s softer than the first-generation margarine stick.” As to saturated fat, the very low-fat diets of the 80s (Dr. Dean Ornish) have been discredited. It is best to use fat in moderation.
