One thing to consider: I read a LOT of archaeological site reports and one thing that is notable is that the archaeologists can always tell the hunters from the agriculturalists by the state of their health as read from bones etc. It was noted very early by archaeologists/paleontologists that agriculture brought tooth decay, many diseases, and shortening of the lifespan. So I don't think I would suggest that it is in anyway good for anybody when it is so notable in the historical record how bad it was.
The grain diet of the [Chinese] peasant warriors stunted their bones, rotted their teeth, and left them weak and prone to disease. In contrast, the poorest Mongol soldier ate mostly protein, thereby giving him strong teeth and bones. Unlike the Jurched [Chinese] soldiers, who were dependent on a heavy carbohydrate diet, the Mongols could more easily go a day or two without food.
Traditional armies moved in long columns of men marching the same route with their large supplies of food following them. By contrast, the Mongol army spread out over a vast area to provide sufficient pasture for the animals and to maximize hunting opportunities for the soldiers.
I'm reading Ray Peat translated articles now and he has covered the causes of this bone degradation quite well.
Firstly the importance of carbon dioxide (CO2) which RP writes a lot about in general. Specifically in the matter of calcium in the bones and excessive soft tissue calcification, sufficient CO2 prevents free calcium from entering the soft tissue cell. And according to him digestion of simple glucose gives several times more carbon dioxide than complex carbohydrates in particular starch. As proof, he cites an experiment on mice deficient in vitamin D in food, one group of mice received 68% starch and the other group received 68% sucrose. The starch group had a lot of bone problems with all the signs of calcium deficiency, but the sucrose group had normally developed healthy bones (albeit lighter than the non vitamin D deficient mice)
And the second culprit RP declares is parathyroid hormone (PTH), which is responsible for the leaching of calcium from the bones. He blames low-protein diets (less than 0.8g/kg body weight) for PTH production; adequate protein intake inhibits PTH production.
So low-protein, high-starch farmers' diets made us sicker, which is something we do not get from nomads who eat mostly milk (lots of calcium + casein protein) and meat (protein) and at the other end of the dietary spectrum the high-carbohydrate Kitawans, Tukisenta and Okinawans in their diets 60-90% of calories come from carbs and although they are low-protein (in the Okinawan diet carbs to protein are 10:1, and the Tukisenta have 25:1), but they get plenty of sun for Vit D and their diets are based on sweat potato, which have a sucrose-to-starch ratio of ~1:1. i.e. enough cellular carbon dioxide.
