I have argued for years that we do not have a health care system in America. We have a disease-management system - one that depends on ruinously expensive drugs and surgeries that treat health conditions after they manifest rather than giving our citizens simple diet, lifestyle and therapeutic tools to keep them healthy.

I find that low protein diets often contribute to improvement in patients with immune system problems ... In fact, it would be hard to become deficient in protein in our country even if you tried.

The most common objection that I hear to walking as exercise is that it's too easy, that only sweaty, strenuous activity offers real benefits. But there is abundant evidence that regular, brisk walking is associated with better health, including lower blood pressure, better moods and improved cholesterol ratios.

Routines may include taking a warm bath or a relaxing walk in the evening, or practicing meditation/relaxation exercises. Psychologically, the completion of such a practice tells your mind and body that the day's work is over and you are free to relax and sleep.

Dietary fat, whether saturated or not, is not a cause of obesity, heart disease or any other chronic disease of civilization.

The choice is ours: we can keep on craving what we don't have, and so perpetuate our unhappiness, or we can adjust our attitude toward what we do have so that our expectations conform to our experience.

If we can make the correct diagnosis, the healing can begin. If we can't, both our personal health and our economy are doomed.
