I'm sure all of this is correct, but you're forgetting one thing: potatoes are the only one of these you can grow enough of to eat at home, as long as you have space for a bucket or sack or two of soil, and which basically require zero processing aside from applying heat to consume.

I agree with you that we shouldn't actually need to know or use any of this information, and as a poor disabled person I also know that growing your own food isn't always an option for everyone, but if it is an option, I think it at the very least puts potatoes back in the running.
