Wa'il, if you're interested, st john's u's BB system carries a paleofood listserve, the archives of which can be read by the public, too. Sometimes it looks a little odd...lots of nick-picky meanspirited fights about such things as how un-paleo vinegar is.

But if you want to simply read on the topic, you can do so for months by following the links off

http://www.paleodiet.com/

the BB is linkable off there, too.
