Canned goods are cheap and easy.
You get the picture. Boring? Yes. Nutritional & filling? Yes.
If you believe you are going to need foodstuffs with longer shelf lives than canned goods, you need to buy LOTS more ammo and learn how to hunt and dress game....and hope you don’t get shot in the woods by the other thousand people hunting the rapidly disappearing game at the same time.
If you have got food etc to last 2-3 months you’re as good as it gets. Because after that, if order isn’t restored, all bets are off. You are much more likely to die of other things than hunger.
PS I have only one medicine that I can’t live without and I keep 15 months supply on hand at all times. I paid cash. No insurance company can tell me I am only allowed 30 or 90 days supply. They can only say they won’t pay for it.
