So far a Vegan who implements this diet, all that's left for them to eat is Fruits and Veggies then no? That would seem like you're missing out on a lot of different vitamins, minerals and various other goodies.

Plus the how long we've been eating grains for sounds like a pretty bad argument to me. The reason I'd guess why we only started eating grains 10k year ago is because that's when we learnt how to handle them and what we can do with them that'll be edible.

Also, from what I roughly recall of history, the prehistoric people first started hunting for food and mostly ate meat with some berries. Then, after they were able to farm, they started growing veggies (and possibly fruit). Do we at that point determine that the length of time we're eating fruits/veggies isn't enough also and just eat meat? So what do vegans at this point eat, water.

I'm not trying to be difficult here or anything nor have I read the book yet. Each person is also free to do what he or she wants so I'm not out attacking personal calls on diet. I'm just trying to say that be very careful what you eliminate. Some of the nutrients you might not even realize you're lacking until years later when problems start occuring. At that point it might be hard to trace why they happen too.
