I now have the answer to a post I made some time back- about the lysine content of the paleolithic diet- it is much higher than the cereal diet. I thought this might be of interest to the group. Reference: Cordain L, Cereal Grains: Humanity's Double Edged Sword. World Review of Nutrition & Dietetics, 1999;84:19-73 This question arose due to beng aware of the late Linus Pauling's resolute promotion of Vitamin C and Lysine as a panacea for heart disease and other illnesses. Pauling was a Nobel Prize winner in chemistry 1954 (I think it was to do with quantum theory) and a Nobel peace prize in 1962 I think. The establishment rejected Pauling over his medical theories (he wasn't a medico) - but his followers are still around. I always think Nobel Prize winners can probably see things that aren't obvious to others. I don't know enough about Pauling's theories to make any meaningful comment on them, and a lot more knowledge has accumulated since he first expounded his theories- but it's interesting, especially as paleodiet is so high in Vit C and Lysine!
