5. Peanut butter with hydrogenated oil
Conversion of liquid vegetable oil into solid fat is called hydrogenation. It is a chemical process that is widely use in the food industry. Not all brands of peanut butter contain hydrogenated oil. Avoid the brands that have this kind of oil in their ingredient list. All that peanut butter is supposed to contain is peanuts and salt. Switch to peanut butter that is healthy and organic.
