Something’s fucky here. The best-qualified people to write nutrition-focused books — dietitians — are at the bottom of the list while all the quacks are leading the pack. All the authors with little to no training in nutrition are the ones who the general population takes nutritional advice from.

But there is more. The researchers evaluated the profile, careers, and claims of some of the authors:

• One author was listed by Quackwatch in a list of “Promoters of Questionable Methods and/or Advice.”
• One author was investigated for research fraud and then retired.
• One author lost his ability to practice medicine and was investigated by the New York district attorney for promoting questionable health practices.
