Say it ain’t so! Put down your spoons, and let’s talk about the favorite protein source for many. It’s easy to eat with some apple slices before a workout, or dip celery stalks into. Unfortunately, due to the growing process, it may be slowing your metabolism with something called aflatoxins, a type of fungus.

Peanuts are also a common food sensitivity. Popular peanut butters are usually made with high sugar content as well, making that smear more of a dessert than a healthy snack.
