Thanks for the info. I'm not strictly Paleo. I'm just looking for a diet I can live with, longterm. I figure something based around meat, fruit and veg is pretty good, with the occassional cheat meal if I go out with friends or on other special occassions. Currently I consider myself doing really well because I've not eaten chocolate or desserts for about a month...so the idea I can't eat anything other than chicken and broccoli for the rest of my life isn't greatly appealing. :-)
As long as I know which foods should not be consumed too often, that's fine by me. It's always a bummer when you find out an apparently healthy food you have grown to like turns out to be not so healthy after all!
