juuan, you will eat a panniers worth of food every couple of days. you will NOT be able to resist. your caloric needs will be huge. don't worry about the food spoiling, unless you want to carry milk or steak tartar. and then there's dry milk for that problem.
do you cook much at home, and how old are you? I'm curious because i see a lot of confusion on your part regarding foodstuffs, etc...
