It will be interesting to see what Cordain says. If we define paleo as only foods that could be eaten raw, then most beans wouldn't be defined as paleo. I think there are lots of non-paleo foods that contain tremendous amounts of anti-oxidants -- cocoa and coffee both come to mind. Mexicans consume lots of chocolate -- perhaps that contributes to their lower colon cancer rates along with more sunshine, exercise, less processed foods. Coffee reduces colon cancer risk too. In fact, according to the study below, instant coffee contains more anti-oxidant activitiy than cocoa and green/black teas. Don't know if this would hold true if the cocoa was made very strong ie 2 tablespoons in water. Anyway, although I adore beans, they are far too star chy for me to consume in any significant quantities without gaining weight. Amongst the less starchy (aside from string beans) would be adukis and black-eyed peas. http://www.ncbi.nlm.nih.gov/entrez/query.fcgi? cmd=Retrieve&db=PubMed&list_uids=11453788&dopt=Abstract
