My concern was that the way post was written it looks as if it's on the OCF recommended book list.

Conversely Quackwatch is the OCF reference list:
Quackwatch, Inc.
http://www.quackwatch.org

Quackwatch, Inc., a member of Consumer Federation of America, is a nonprofit corporation whose purpose is to combat health-related frauds, myths, fads, and fallacies. Its primary focus is on quackery-related information that is difficult or impossible to get elsewhere. Founded by Dr. Stephen Barrett in 1969 as the Lehigh Valley Committee Against Health Fraud, it was incorporated in 1970. In 1997, it assumed its current name and began developing a worldwide network of volunteers and expert advisors.
