Itchy, FYI, it takes a while to identify who the semi-trolls on the board are. They pretend to be primal but will post some stealthy anti-primal study, hoping to convince some primals to revert to semi-CW. The original poster is one of these.
IMO legumes should be in the 20%. I am so accustomed to red kidney beans in chili that it feels weird to leave them out. And I like occasional hummus. I don't feel the need for any other legumes.
