Processed foods, particularly cakes, breads, crackers, chips, and cereals may contain some fat and manufacturers a long time ago found that if they used a very stabilized form of fat, the food would not spoil and have a long shelf life. Any food with a long shelf life is probably not good for you. If you see the word “hydrogenated” on a label, think, “Do I really want to be fat and old and sick before my time?” Hydrogenated oils and trans fats produce lots of free radicals (see #2).
