Chimps have indeed been known to partake in grains. (PNAS, (2007), 104(9), 3043-3048.) Admittedly, itís not their preferred food (that would be fruits), but then meat and bugs arenít their preferred foods either.
As mentioned as well, asking me to find an article disproving WGA function would prove nothing. Correlation does not equal causation. This would be akin to asking someone to prove that eating honey does not raise blood sugar, and then claiming since it DOES raise blood sugar, eating honey MUST cause diabetes. It neither proves nor disproves anythingÖ
To verify that no food has all nutrients, the beef liver lacks calcium and vitamin D, and has such miniscule amounts of vitamins C and E, and magnesium (a mere 1% of RDA) and very little thiamin and manganese (4 and 5% respectively), that it would be difficult to obtain the RDA from this. As noted above, it is also completely devoid of fiber. On the contrary, wheat has not only fiber, but also manganese, magnesium and in high quantity (35% RDA or moreÖ), as well as a small amounts of calcium and vitamin E (5%...more than beef liver).
I didnít mean to offend by mentioning mammals other than chimps that ate grainósimply responding to the claim that no other mammal except for us who eat grains, which clearly was incorrect.
Lastly, I donít begrudge you experimenting with your diet. And hopefully you donít begrudge us omnivorous grain eaters who point out that grains can indeed be eaten successfully without health ills. Itís okay for people to have different opinions about something so controversial and unproven, and if I can accept that you choose not to eat grains because you feel they harm your health (and I doÖ) then you must accept that others can eat them because they believe theyíre fine. (Stating our own views and backing them up should not be seen as a personal attach, and I hope you donít view it this way).
