It is not surprising that the expanding American waistline is correlating to a growing need for health information. According to the Centers for Disease Control and Prevention, obesity contributes to an increased risk for hypertension, diabetes, heart disease, arthritis, and some cancers. And though general medical books that list 100 different disorders may be handy for ready-reference, they often don't provide enough information on any one specific disorder. This article illustrates how various books on health topics have flooded the market. It concludes that publishers offerings will affect librarians and their patrons in that there will be a continued need for information on health topics; smaller libraries may have a tough time keeping up with the purchase of all those individual titles, however. Books with emotional components and humor should continue to be popular. Diet and exercise titles, too, though librarians who have cringed in the past at handing patrons fad diet books should be happier with the trend toward realistic diets and authoritative works. Not only are we living longer, healthier lives, we're younger than we ever thought we were.
