Anything containing (Partially) Hydrogenated Vegetable Oil, Margarine, Vegetable Spread, or Shortening is usually loaded with Trans-Fats. Trans-Fats are very bad for you and Trans-Fat content isn't even listed on the label. The use of saturated fat varies program to program. Atkins and many others have no problems with it. But, I was just reading the Paleo Diet book and they slam Saturated Fat pretty bad. But, even they also say to stay away from Trans-Fat.
