Don't forget about foraging also
Take for example silver weed (pic rel)
It's root has more carbs than potatoes pound for pound, it is a great famine food that could save your life. I have some that grows in my garden. I let it grow there. It spreads like mad however

Another honourable mention is chickweed. And Goosefoot. Willowherb or (fireweed if you are American). They are packed with vitamins. You can also cook rowan berries and eat them. There are is literally so much food right at your feet and all around you, educate yourself and you will never starve especially if you couple foraging with growing vegetables, fishing and livestock of you have the room and the means to feed them. If you don't know these skills, then you are literally niggercattle who's life relies on shops and supermarkets. If the supply chain fails, you will starve
