Many processed foods are full of excess sodium, sugar and fat. An easy way to clean up your diet is to look at the ingredient list on packaged foods. If the list is long or includes lots of ingredients that you can’t pronounce, try to stay away from it. Instead, make healthy homemade versions of your favorites, like macaroni and cheese, tomato sauce or granola bars. And remember that not everything that comes out of a box, bag or can is bad for you. For example, whole-wheat pasta, baby spinach and chickpeas are all “clean” packaged foods. They are minimally processed and provide good-for-you nutrients like fiber and vitamins.
