#1 Worst Food: Processed Meat
According to Webmd.com, the American Institute for Cancer Research says meats preserved by smoking, curing, or salting, or that contain chemical preservatives, are linked to an increased risk of colon cancer. These products also tend to have lots of salt, fat, and cholesterol, and very few nutrients, like fiber.

They may look tiny, but frozen dinners can be loaded with calories. Livestrong.com found one popular national brand of chicken pot pie contains 64 grams of fat and 1,020 calories per serving. And while the diet versions of these frozen foods may be low in fat, they are heavily processed and are often high in sodium.
