Egyptian Mummies Diagnosed With Clogged Arteries
"Ancient Egyptians did have access to meat, though Thomas says their diet consisted mostly of grains, fruits and vegetables."
Personally, brown rice and sorghum causes psoraisis within a couple of hours of ingestion. Corn to a lesser degree. Takes two weeks to clear up. Wheat doesn't seem to have acute symptoms for me, but chronic exposure leads to arthtitic pain in my fingers.
