Ready for a hike? According to topix.com, one should consider these three things when packing for a day on the trail:
Healthy Carbohydrates such a as granola, apples, celery and carrots or pita with hummus.
Good-for-you-fats like peanut butter and jelly or a low-sugar trail mix (think less chocolate chips, more coconut)
High protein treats like hard-boiled eggs and string cheese.
(And don't forget proper hydration.)
