There is not much about nutrition in this chapter: Although it is certainly important to eat a nutritious diet, nutrition has little direct effect on our hunger and eating. However, while I am on the topic. I would like to direct you to a good source of information about nutrition. Many popular books on nutrition are of questionable validity, and even governments, inordinately influenced by economic considerations and special-interest group, often do not provide the best nutritional advice. For sound research-based advice on nutrition, check out an article by Willett and Stampfer and the book on which it is based.
