My comments are from a non picky eater with no dietary restrictions. On my longer hikes between replenishment points on the Continental Divide, Great Smoky Mountain, Pacific Coast and Philmont, I carried assorted dehydrated foods to meet my calorie intake for the time of the year. I used a turkey basting bag to reyhdrate the food with warm water. Some of those places now prohibit using a turkey basting bag for food warming. I avoided jarred or canned foods with a preference for pouched food since all trash is carried out. A few places such as Big Bend required toilet paper to be carried out because of the arid climate. My Philmont trek was 12 days which covered just over 100 miles since my 2 sons picked the extreme trek.
