The "fat" information out there is confusing. Experts now recommend that we stay away from trans fats because they raise bad cholesterol and lower good cholesterol. But what are trans fats, anyway? They are the kinds of fats often found in cookies, crackers, and margarine. On ingredients lists, they show up as "hydrogenated" and "partially hydrogenated" oils. But be careful: Some "trans fat-free" products now contain tropical oils that are high in saturated fat, another bad fat. If you're lucky, your city has banned trans fats (New York and Philadelphia) in restaurants - hopefully more will follow!
