the real questions are:

1 - what did people eat before the agricultural revolution

2 - what do the highest class, most intelligent, highest performance people eat today

the answer to both questions is - not grain or seed oils

you're supposed to be intelligent yet you do not seem to understand that what the average person eats is simply what is cheapest, which tells us a lot about agriculture and food processing technology but tells us NOTHING about human health

human genome did not evolve around tractors and food processing plants
