Promoters of Questionable Methods and/or Advice
Each of the following has been involved in some way with the promotion or administration of questionable health products and/or services or with opposition to beneficial methods. Many of them have written at least one book that I believe contains invalid information. Most appear to hold sincere beliefs. Those marked with a red asterisk (*) have been subjected to regulatory or enforcement action. Nonaccredited degrees are marked with black asterisks (*). Each asterisk represents one action or dubious credential. Click on each name to see the reason they are on this list. The Encyclopedia of American Loons has additional information on some of the people listed below and many others who are not.
