Americans are more concerned than ever before with diet and nutrition. According to one study, dieting Americans spend $33 billion annually on weight-loss products. Nevertheless, obesity is on the rise in spite of being a known risk factor for many chronic diseases. It is not surprising, then, that there has been a general reappraisal of nutritional practices among Americans of all ages.
The new edition of Diet and Nutrition Sourcebook provides updated information about basic dietary principles and guidelines for people of all ages as well as for people with specific medical concerns. In addition, the new edition contains information about developments that have occurred in the field of nutrition science since publication of the first edition in 1996.
