The ones that have a candy-like coating are most likely to contain trans fat. Read the ingredients label carefully and look for bars without the partially hydrogenated oils.
Most mixes have trans fat. Make your own by heating skim milk in the microwave and adding some unsweetened cocoa and sugar.
The simple and healthy alternative is to air pop your own. Then flavor it with fat-free seasonings.
Anything baked with shortening will contain trans fat. Ask bakeries or restaurants what they use. At home, bake with canola oil instead.
Pancake and Waffle Mixes
Most contain as much trans fat as cake mixes. Make your own mix or check the health food store for packaged versions without the hydrogenated oils.
Most processed peanut butters include partially hydrogenated oil. The good news is that these products typically contain less than two percent of the unhealthy oil, so by FDA guidelines they're considered "trans fat free." To go truly trans fat free, buy natural peanut or almond butter (the oil will separate).
Look for dressings with no hydrogenated oils, or better yet, make your own with olive oil and vinegar and your favorite herbs and spices.
The ones you find in the interior aisles of the store (which can stay fresh forever) probably contain trans fat. Instead, choose the ones in the refrigerated case (especially organic versions), which usually don't have trans fat in them.
