This is a very practical health book that takes the most basic precepts of holistic medicine (nutrition and sleep and exercise!) and tells you what the nutrients do for you, and lists each sort of medical malady and how you can help yourself by simple, inexpensive and really, not unpleasant methods to optimize your health.
This book harks back to all kinds of ancient medical traditions, from Hippocrates and Ayurveda (essentially, let food be your medicine, and take care to sleep and exercise.)
The discussion of micronutrients and vitamins and what they specifically do is excellent; one of my doctors years ago explained to me that our cells are surrounded by liquid (the interstitial fluid, to be exact) and this liquid layer surrounding each cell contains our micronutrients; vitamins, minerals and anti-oxidants. These nutrients form a sort of defense system, preventing free radicals, which are damaging molecules, from entering the cells and doing damage to the DNA, for example. So by staying properly hydrated, properly nourished with quality food and good nutrients, you can keep your cells healthy and keep disease at bay. It's more complex that that--and our foods today, over-processed, full of sugar and white flour that is not supplying healthy nutrition, has to be supplemented by vitamins and minerals. Or else, as the book recommends, substitute healthier foods. The advice given here by Dr. Teitelbaum squares with what my own doctors (the ones who embrace holistics) have told me, but I think the explanation and organization of this book are much simpler and easier to understand for anyone who is trying to live a healthy life.
The discussion on sleep is important, too. It's estimated that Americans are chronically sleep deprived. The healing process of building back up the body happens while we rest, and the author reminds us that sleep is not to be underestimated as an important health component. Likewise, exercise and movement help arthritis, bone health and many other body functions--not only musculature but internal organ function as well.
This is a simple book filled with easy-to-understand information and a lot of well-organized facts about food supplements, for which I think the book is valuable on its own. But the basic tenents here (eat well, sleep well, move well) listed by what ailment is aided by and HOW, make this a very simple book to follow to improve your basic health. Highly recommended reading for anyone.
