Fasting and natural diet, though essentially unknown [in today's U.S.] as a therapy, should be the first treatment when someone discovers that she or he has a medical problem. It should not be applied only to the most advanced cases, as is present practice. Whether the patient has a cardiac condition, hypertension, autoimmune disease, fibroids, or asthma, he or she must be informed that fasting and natural, plant-based diets are a viable alternative to conventional therapy, and an effective one. The time may come when not offering this substantially more effective nutritional approach will be considered malpractice.
