IMHO: Depends what you're hunting, where you're hunting it, and how you'll be moving... if you're going to stick pretty close to camp and can use a cooler, it doesn't really matter too much. If you're hunting something that has acute sense of smell, probably want to avoid stinky or lingering foods.
IMHO for snacks: Keep your sugar consumption low. Granola bars, jerkey, nuts, dried fruits. You want high calories but lower sugar as to avoid peaks and crashes. Plenty of water! Probably want to avoid heavily processed foods like bags of chips too.
Everyone has their own tried and true foods and you can probably get away with eating / packing whatever you have room and need for. Keep it simple. I'll pack up 3 sandwiches for each day and keep them all in a cooler so they don't get funky. If you're leaving from camp, pack up snacks and water.
Be safe out there ktkheatsfan. Make sure you tell someone like a friend or family where you're going in the event you get lost or something happens.
