Dr. Benesh was treating people according to the philosophy he adopted as a Chiropractor and Naturopath. Both fields believe that the body has the natural ability to heal itself if given the opportunity to do so and when cleared of any hindrances. Nutrition and fasting have been a key to health for centuries - even the Bible discusses the importance of both. History will show these practices in place in cultures around the world and are still used today, especially in countries where they must rely upon the resources they have at hand.
We each have a choice to make in our own health care, no one can make that choice but us. There is plenty of information available to make an informed decision, ignorance is not an excuse in this area. Dr. Benesh was a good man, he was my physician for several years until I moved, and I learned much from him about caring for the body in a natural manner. The body will tell much about itself from the analysis of urine and other body fluids as well as its external condition: skin, eyes, hair, teeth, gums, nails, etc. Even medical physicians look at all of these when evaluating a patient. Hence vital signs, physical observations, and subjective information from the patient. Physicians take in all this information, even if the patient is not fully cognizant they are doing so because it seems so "routine", they take it for granted without fully understanding "why". So many people do not care about these seemingly "trivial" things the physician is doing, they just want a prescription for a medication to make it better.
I believe there is a place for both approaches to medical care. I'm not dismissing the importance of traditional medicine, but we should not condemn what we don't understand. The body was designed to heal itself in most situations and should be given the chance to do so, but that also requires caring for the body as it was intended to be cared for and the modern diet and lifestyle doesn't meet these requirements in most cases. Mental attitude has a huge role to play also, and looking for the good in things rather than focusing on the negative goes a long way in supporting the health of our bodies.
Do your homework, there is plenty of research and information to support alternative medicine. Even the traditional medical community is pushing "wellness" over the traditional healthcare approach of the past. They are acknowledging that we need to invest our time, money, and resources in preventative care and reduce the amount of money and government spending to care for the millions of people with preventable diseases....obesity, diabetes, and cardiac disease. Cancer from smoking and liver disease from drinking, just to name a few . The drug companies aren't too happy with this model, but the physicians who watch people die daily from preventable disease and truly care about their patients, are all for it.
