The body requirements include essential fatty acids, carbohydrates, complete proteins, and every known vitamin and mineral. If only unrefined foods are eaten, nutrients still unknown will probably be furnished. Hundreds of thousands of animal experiments have shown that if a single nutrient or any combination of nutrients is omitted, disease is produced. There can no longer be doubt but that people produce illnesses in themselves by selecting diets as faulty as those that cause disease in animals. Yet, provided injury is not irreparable, a diet including all nutrients in ample amounts can restore health. Because this fact has been repeatedly proved beyond question, no person--not even a physician, in my opinion--has the right to impose an inadequate diet on another individual. There are times, of course, when these rules cannot be applied, but during such periods health is being tom down rather than built up.
