15. Processed foods that claim to be low fat
First of all, we can dispel with the myth that fat is bad; your body needs some fat to function properly. Cutting out fat entirely can lead to brittle hair, dry skin, and a host of other issues. Plus, when you remove fat from foods, those foods lose much of their flavor. To replace that flavor, companies need to add copious amounts of sugar or salt (or both), which is worse for you than a little fat. It’s probably wise to avoid as many processed foods as possible, but you especially want to avoid those that make claims of low fat.
