If the word "hydrogenated" is anywhere in the ingredients, I would urge you to stay away. There is a big butter vs. margarine debate (which I prefer to stay out of) but partially hydrogenated oils or trans-fatty acids stick to your arteries and are perhaps even worse than cholesterol.

With that being said, I use Benecol or Smart Balance. These taste great and have no hydrogenated oils and are supposed to actually raise healthy cholesterol levels while lowering bad ones. Who knows. I believe both brands also come in Light. I know Smart Balance light has 5 grams of fat as opposed to the traditional 10.

Just my two cents.
