For decades Consumer Health: A Guide to Intelligent Decisions was the only textbook available for college classes on the subject, and it is still the best: the most comprehensive and the most reliable. It was first published in 1976, and it has clearly had staying power. An updated 9th edition has just been released. The authors have changed over the years: this edition’s authors are Stephen Barrett, William London, Manfred Kroger, Harriet Hall, and Robert Baratz. It’s an invaluable compendium of information that would be useful to any consumer, and it’s unfortunate that McGraw-Hill is marketing it as an expensive textbook ($163).
What exactly is “consumer health”? The book’s preface and the table of contents are available here. They will provide the long answer to that question. The short answer is:

In May 2008, the article “Why the NIH Trial to Assess Chelation Therapy (TACT) Should Be Abandoned” was published online in the Medscape Journal of Medicine. The authors included two of our own SBM bloggers, Kimball Atwood and Wallace Sampson, along with Elizabeth Woeckner and Robert Baratz. It showed that the existing evidence on treating heart disease with IV chelation did not justify further study, and that the TACT trial was questionable on several ethical points. Their ethical concerns were taken seriously enough that enrollment in the trial was put on hold pending an investigation. It has now been re-opened after a few band-aids were applied to the ethical concerns. The scientific concerns were never addressed.
I have seen many critiques of the Atwood study, and not a single one has offered any cogent criticism of its factual content or reasoning. Most of them could have been written by someone who had not bothered to read beyond the title. Their arguments can be boiled down to a few puerile points that can be further simplified to:
(1) I believe the testimonial evidence that chelation works.
(2) Atwood and his co-authors are bad guys.
Now Beth Clay has chimed in with an article entitled “Study of Chelation Therapy Should Not Be Abandoned.” I found it truly painful to read, but even the worst has some value as a bad example. Clay’s article could be used for a game of “Count the Errors.” I will point out some of them below. (more…)
