I read in the Aug 2006 issue of the American Journal of Geriatrics Society that from 221 AD until the end of the late 1800’s, in the far East, traditional doctors (Influenced by a Qigong view of medicine) lived the longest at an average of 75 years (same as many today).
Buddhist monks lived an average of 67 years.
Just for comparison, emperors lived an average of 41 years!
Now, their health regimen included Qigong which is supposedly healthy and they used a variety of medicinal herbs and traditional medical treatments, the efficacy of which are up for debate.
That being said, here is an oft repeated Qigong statement about maintaining health: “Avoid the Five Cereals or Grains”. It appears in virtually all ancient works on the Qigong diet.
The “Five Cereals” are: rice, millet, wheat, oats and beans.
One ancient text reads “If a grain enters your mouth, do not hope for eternal life!”
So unless these guys were chowing down on potatoes or some other carb rich source (unlikely since the “Five Cereals” were the staples back then), it is likely that they were ancient ketoers or close to it and outlived their rice heavy and vegetarian contemporaries (Buddhist monks). They probably ate veggies, eggs and meat, avoided high carb grains and lived to ripe old ages without modern medicine! And obviously getting to eat whatever you feel like whenever you feel like it kills you young so the emperors were outlived by the doctors by 34 years on average. Wow.
Interesting, eh?
