I listened to a video yesterday explaining how like 65% of our cultivated crops are from North America, and how the potato's stability, greater calorie count, and ability to grow in places other plants couldn't was the reason why famines went from once every 2-3 years to once every decade or more in Europe, and effectively lead to the dominance of Northern Europe over the Mediterranean. Basically the reason Rome and Greece were so powerful is because they were situated in areas where crop failures were more rare and so they could support larger populations, whereas Northern Europe had a crop failure every 2-3 years which resulted in significant mortality.
Also compare calories gained per laborer in grain based societies vs rice based societies. Rice based societies worked for their calories so much harder over many successive generations that they are smaller as a result, and if you compare even North vs South Koreans, the southernors are a few inches taller on average, heavier, heartier stock. It is no winder rice based societies are more collective and less individualistic than theie grain counterparts.
Sociology is food is very interesting. But early in soc 101 you learn that specialization is a function of surplus, and that the most important societal surplus is food.
