In case the economy happens to completely crash, there is yet another food to add to your arsenal. Canned foods and non-perishable items are great. Nuts are great. Bottled water is a must. Can’t go without ACV (apple cider vinegar). But if you find yourself living in the wilderness, but still want to take a little piece of civilization with you, stock your gear full with as many McDonalds hamburgers as you can. They can last up to 10 years and are perfectly good to eat at any time. And this is no joke.
