In my view stocking up the types of food that keep well, provide the calories and other nutrients required for healthy living without being bulky are what is needed. If I or anyone else can get fat during a shtf more power to you. I have the normal rice, beans, canned meats & fruits. Some pasta canned sauses & miscellanious other stuff. Some people want to eat healthy diets which is great, my main concern is having enough food. Hopefully gardening and animal husbandry work out.
