The medical school educational system is not designed to teach students the fundamentals of health, what causes disease, and how to correct it. Nutritional deficiencies are the cause of most diseases and if you read the scientific medical literature you'll see this. But these scientific medical advances are not being taught at medical schools. No one is pushing it because of the lack of profits to be generated. Nutrition is not Alternative Medicine Nutrition is not alternative medicine.
Nutrition is medical science.
The study of nutrition is the study of the nutritional basis of disease. If anything is alternative medicine, it is the medical arts that are being practiced by mainstream medical professionals today. Over many centuries, physicians have learned that when symptom A occurs, and the physician gives drug X, performs surgery Y, or gives radiation Z, the symptoms subside. This is not science, it is art. That why doctors today are called practitioners of the medical arts.
