Illness or disease is only Nature's warning that filth has accumulated in some portion or other of the body; and it would surely be the part of wisdom to allow Nature to remove the filth, instead of covering it up with the help of medicines.
Someone who has thought rationally and deeply about how the body works is likely to arrive at better ideas about how to be healthy than someone who has followed a hunch. Medicine presupposes a hierarchy between the confusion the layperson will be in about what is wrong with him, and the more accurate knowledge available to doctors reasoning logically. At the heart of Epicureanism is the thought that we are as bad at answering the question "What will make me happy?" as "What will make me healthy?" Our souls do not spell out their troubles.
You must know for yourself, directly, the truth of yourself and you cannot realize it through another, however great. There is no authority that can reveal it.
We cannot step aside and say that we have achieved our goal by inventing a new drug or a new way by which to treat presently incurable diseases, a new way to help those who suffer from malnutrition, or the creation of ideal balanced diets on a worldwide scale.

I expect and hope that orthomolecular medicine, within the next five to ten years, will cease to be a specialty in medicine and that all physicians will be using nurition as an essential tool in treating disease.
