Snacking can actually be good for you if you make good choices. Avoid high-sodium, high-cal treats like potato chips. And although baked potato chips are better, they're still too salty and pretty much empty calories. Instead, think of snacks as nutrition boosters. For example, the next time you have a craving, try nuts, fruits, veggies, yogurt, or cereal bars to help meet your calcium, veggie, or protein requirements.
