Does the blood type diet really work?
Not really. This diet, developed by naturopathic physician Peter D’Adamo, is based on the theory that the different human blood types—A, B, AB, and O—require different diets for optimal health. D’Adamo gives very detailed recommendations for what each type should and shouldn’t eat. For example, he says shiitake mushrooms are great for type B’s but bad for type O’s. (For the record, I encourage everyone to eat shiitakes. These flavorful mushrooms help the body regulate cholesterol, and they also help to guard against viruses and cancer.
