Always go with fresh foods as much as possible. They are loaded much more with the stuff that keeps you healthy. Foods found in bags, boxes or cans have been altered and highly processed, making them empty of the essential nutrients you need.Your snacks can be a smaller version of your meals. Remember to always have protein and carbohydrates together: humus and carrots, a piece of bacon and half an apple, almonds and grapes.Remember,if you can have only a square,try some dark chocolate as a little sweet snack—don't expect it to tide you over if you are actually looking for substantial nutrition—it's just a little taste that's all.
