I have never been a believer in completely iliminating anything from my diet. I am taking gluten due to health issues only. I feel that if I completely give up any thing that I really crave (unless due to illness) I am doomed to fail. I really believe in a healthy diet and craving can be added in moderation.
Don I love sweet potatoes. I just add a little smart balance after baking. I could probably eat them plain if I needed to.
