I rotate through several big boxes of granola bars, quaker yogurt bars (100 cal per) tend to melt a bit, but whatever, quaker chewy trail mix (150 cal per) are kinda sweet for some people, some contain peanuts, but otherwise would be good kid food as they are very soft. and quaker oatmeal to go (220 cal per) good, but need a lot of water to eat. I tend to keep more food around (just found the mars bars stashed in my parka) than most people, I have no R value, so as soon as my body runs out of food, I get cold very fast. If you have any kind of diet troubles (foods that don't agree with you) look for stuff that you can eat on a regular basis, then you'll know if it will work with your digestion. dehydration form diarrhea isn't helpful in a a survival situation. My dad was on a salvage/ repair crew that recovered a downed small aircraft in northern canada, and knew the pilots (who survived). one said that he was going to live just so he could yell at the guy who packed beans, rice, and pasta in the survival kit. all that food, and no water, or wood for fire within a hundred miles. luckily they only had to hang out with the crashed plane for day as they were able to radio their landing site in before they went down.
