If you haven't ever lived at subsistence level you may not understand what you are facing in reality. Food is food, better to have a deformity than to be dead.
There are tons of greens in everyone's backyard in America right now that you can eat. Half the weeds in your yard are editable and would fill in all the missing nutrients.
Education is the problem here, maybe not so much resources. (unless famine?)
But also, when I eat the same meal every day, I do feel a certain hunger for other things after awhile, so I don't disagree about nutrients.
You can't subsist on greens, they're 8 calories a cup (47 grams). You would need to eat thirty pounds a day of lettuce out of your back yard. That's polluted urban soil so it would probably poison you whilst you starved.
I was merely pointing out that probably a few bites of greens (not covered in chemicals, where do you live?) has enough vitamins to stave off scurvy and a host of other nutritional deficiencies... not feed you outright.
