Book excerpt: And it answers such questions as: "Are 'organic' foods worth their extra cost?" "Can acupuncture cure anything?" "Will vitamin B[subscript 12] shots pep me up?" "Can diet cure arthritis?" "Will spinal adjustments help my health?" "Will amino acids 'pump up' my muscles?" "Where can reliable information be obtained?" and "What's the best way to get good medical care?" Even if the answers to some of these questions seem obvious, the details in this volume, written in an informative, highly readable, and easy-to-understand style, will astound you. Quackery often leads to harm because it turns ill people away from legitimate and trusted therapeutic procedures. However, its heaviest toll is in financial loss not only to those who pay directly, but to everyone who pays for bogus treatments through taxes, insurance premiums, and other ways that are less obvious.
