These considerations are not based on the rigors of nutritional science which, at its best, deals objectively with the essential components of human nutrition, their minimums and optimums for health, and digestible sources of these essential nutrients in nature. Nutritional science takes the side neither of vegetarians nor meat eaters, but attempts to improve the health of both through better food choices based on nutritional information. In the following chapters, we examine the fat content of different diets and foods. We can observe how the fat content of our diet has changed over history. This may give us insight into why present diets that appear to be the same as past diets, now result in diseases of fatty degeneration.
Some diets build and maintain healthy bodies.
Others do not. In this chapter, we rate the most common diets for oil content and their ability to maintain rebuild health. The newly popular Dean Ornish's diet is another. A third is nutritionist Paavo Airola's diet, which is similar to Pritikin's diet in its makeup, but contains less protein and a better balance of oils. They reverse many of the degenerative changes in cardiovascular disease, obesity, diabetes, rheumatoid arthritis, hypertension, and senility.
