On the subject of food and vitamins - vitamin C is only derived in useful amounts from certain fresh foods - mainly fruit. Of all the vitamins this is one of the most important. I would have a considerable number of vitamin supplements on hand (I do anyway - and use them), and C would be top of the list. Potassium is another food supplemental item lacking in useful amounts in an overly limited diet.
My general food reserve list is topped by things like tinned sardines, beef jerky, basmati rice, pasta, oatmeal, dried fruit, nuts,
coffee, tinned cream. Salt, pepper, spices etc are also on hand in some quantity.
If you are sitting tight or have wheeled transport; fresh potatoes, onions etc will keep fresh under most conditions for a fair amount of time and have great food value. Broccoli is very high in food value and will remain edible for a time unrefrigerated. Some fresh fruits like oranges, and even bananas if they they are really green will keep for a short time. If bought regularly and kept in rotating supply, a fair amount of fresh food can be kept at home without refrigeration and used until it runs out before having to hit the canned stuff.
Barter: scotch, rum, brandy, good cigars, popular cigarettes, coffee. Even if you do not drink or smoke, there are many people who will pay dearly for such things. A few small bottles of each, a few cigars, and a carton or three of cigarettes, some small cans of coffee will keep a long time with a bit of care. If you do like a wee dram now and then, appreciate a good cigar, or smoke cigarettes, etc such comforts might make some other inconveniences and suffering much easier to live with.
Everyone should have
at least one .22 rimfire. Preferably a rifle and a handgun. They are very effective for a variety of uses when employed skillfully, and the ammo is dirt cheap so thousands of rounds can be kept on hand.
