19. Processed cheese
We’ve all seen those bricks of fluorescent orange cheese food on the shelves of the grocery store. They’re not even in the refrigerated section! If the concept of shelf-stable cheese alone doesn’t turn you off, there are other reasons to avoid this cheese-like food product. Mostly, it’s full of additives and preservatives, whereas real cheese is milk and some cultures. Beyond that, it’s also full of artificial colors and flavors, and again, it’s cheese that requires no refrigeration. That’s just wrong.
