This new edition of the most comprehensive text available in the field continues to provide a vast amount of information to enable consumers to make wise choices regarding health products and services. It offers a panoramic view of the health marketplace, while explaining the scientific methods that are essential for validating claims about how products and services affect health.
Everybody needs to read this book to be an informed consumer of health related products and services. I highly reccomend it, even though I HAD to read it for a class.
