Disclaimer (because this is America): I am not a dietitian or a physician. I am a diabetic armed with a giant book called Prescription for Nutritional Healing (Phyllis A. Balch, CNC, 2010) and access to a whole slew of nutritional websites. I experiment on myself constantly, but that does not mean you should. Unless, of course, your doctor says its ok.
