Food must satisfy both physiological and psychological needs. Some people are fine with treating food entirely as fuel and pay no attention to the finer details of what they are chewing and swallowing. Others want a diet that better resembles what they might normally eat at home. Some require vegan food and want as much raw fresh food as possible. Others want wine. Some want junk food. And so on.

The best advice about food is to experiment with it until you understand how you prefer to eat on the trail. It is a problem that admits an endless variety of solutions, so the process of experimentation only ends when you feel like it.
