Scary Ingredient #6: Partially Hydrogenated Vegetable Oil
A semi-solid fat created when food processors force hydrogen into unsaturated fatty acids.

Why it's scary: Partially hydrogenated fats are the principle sources of trans fat in the American diet, and a Harvard study estimated that trans fat causes 70,000 heart attacks every year. The good news: Partially hydrogenated oils are beginning to slowly retreat from our food. Progressive jurisdictions like New York City are starting to restrict the allowable amounts in restaurants, and many chains are switching to healthier frying oil. Still, the battle isn’t over. At Long John Silver’s, for example, there are still 17 menu items with more than 2 grams of the stuff. According to the American Heart Association, that's about the maximum you should consume in a single day.
