Hi I am somewhat new to Primal eating and am taking the primal 21 day challenge. I am also giving up dairy for a few weeks because I think either wheat/grains or dairy are causing some stomach problems for me. So when I try to bring dairy back in to see how it goes is sour cream (reg. full fat) considered primal? That is the one dairy item I miss. I was making a homemade ranch dressing with mostly sour cream and some yogurt for salads, raw veggies.
