Sodium and sugar content and other unhealthy additives are common in processed snacks. So keep them to a minimum if you can't avoid them. Veggie-based snacks are a healthier option. Roasted garbanzos, lentil chips, crisped snow peas and other vegetable and legumes snacks are tasty replacements for potato and corn chips. Popcorn is easy to fix but skip high sodium with a popcorn machine instead of the microwave kind.
