I don't want to try to convince you not to be vegetarian or anything, if that's what floats your boat then got after it, mama. :-) But I do want to address the whole concept of how we ate 20,000 years ago (or even 10,000 years ago...) it was a lot more that a vegetarian diet with "a mastadon thrown in every now and then"
Paleolithic man ate lots of variety of vegetation, berries,etc. That's the "gatherer" part. But they also hunted and this was a large part of their life. It wasn't always big game, they also would have hunted lots of smaller game (including rodents, lol) I just don't get and have never heard that meat eating wasn't a large focus and drive for early humans. Did they always get to eat a large amount of meat daily? Certainly not, but it was something that (and still is in indiginous cultures) humans would seek out for health and survival.
I just think if you are interested in how we evolved to eat, you may really enjoy looking into the research behind traditional food/primal eating. Not that you have to change over, but to educate yourself on the matter. Life long learning and all that!
I make the mice comment as a joke. Guess it didn't work in written format.
I've edited out my initial upset reaction to this post. I hope this thread doesn't get sucked into a debate about meat/no meat. I just want to know if anyone knows of nutritional info for a whole foods, vegetarian diet.
