MREs-Full of sodium, fat, and calories for the most part. Most prepared foods are. Cup noodles, etc. Might be a good thing in summer, when you sweat a lot, but not as a regular staple. I am still a fan of the local grocery store and fresh food. You get to meet people from where you are traveling, sample the local cuisine if you wish, get the fresh vitamins and nutrients you need. When I carry such emergency food, for storms, or days between towns, it is often dehydrated soup or chili which comes in a large bag and is cheap. Still bad, but not so bad. I have to admit I am in the States, and the MREs aren't really that good. Mountain House has a few exceptions that are acceptable, but I may go the dehydrate it myself route. I use a standard issue Stryker Jet-Boil type stove, good kit and better than the original Jet Boil at about half the price.
