I have been listening to the Personal Profile CD from T-Tapp. It has information on blood type and eating for your type. This prompted me to check into the information from Peter D'Adamo's book "Eat Right For Your Blood Type". I am a type O and on the food lists, alfalfa is listed as a food to avoid for type O. Does anyone have any further information? I have been taking alfalfa as part of the CRT system since around the end of January. It does sometimes make me have a slight heartburn sensation with burping.
