If your buttery spread can stand on its own, it's the fats that are making that happen -- specifically, its saturated fats. Saturated fats are more solid than, for example, a monounsaturated fat such as olive oil, and these fats are bad for you because they expand your waistline, raise your bad cholesterol levels (while lowering levels of good cholesterol), raise your risk of heart disease and raise your risk of suffering a stroke.

Stick margarine used to contain trans fats, also known as partially hydrogenated oils, and some brands still do (always read the ingredient label); trans fats are considered one of the worst -- if not the worst -- fats for you to eat.
