Sorry to revive such an old thread but I read through the entire thing and thought it was quite interesting. I am currently reading the Paleo Solution and am going to try a 30 day paleo trial starting january 1. Ideally I would eventually like to get to raw paleo but we'll see how it goes.
I did a 30 day vegan trial back in January of this year and it went well I'd say. A huge huge huge improvement from the SAD. But considering I was literally eating the worst processed foods, fast food, crap that probably shouldn't be called food, any diet with more natural foods probably would have been a big improvement. I eventually transitioned into being a moegan (my term for mostly vegan) and am starting to incorporate meat again now to be ready for Paleo.
One thing that I didn't see addressed in this thread that has always concerned me is the need for vitamin B-12. From what I've read, you need vitamin B-12 to survive (albeit not a lot and problems can take many years to surface) but when on a vegan, raw, or fruit diet, how does one get vitamin B-12 in the diet without the use of supplements or fortified food? This one concept kinda busted the notion of being vegan to me because any supplement or fortified food is not "natural" or found in nature. So if the fact that you need B-12 to survive is true (is it?) and the fact that the only way to get it in nature is by eating animals (is that true too? I think it technically comes from bacteria?) then our ancestors would have had to have eaten animals even just a tiny amount, confirming that we are indeed supposed to be omnivores. If anyone can address this issue I would greatly appreciate it!
