I had a thought about growing 100% of my own food.
"Diet should be based on climate and land first, then optimized for labor, then adjusted for preference."
I know what my culture recommends I grow.
I know what my preferences are.
But neither of those things mean I can grow those things and meet all of my food needs from my specific land and climate.
I love wheat, but I might need to grow flour corn.
I love bush beans but I might need to grow fava beans.
