Nutrition science suppresses dissent through ad hominem, not evidence

The pattern runs from Yudkin to Teicholz. When Nina Teicholz published a BMJ article critiquing the scientific basis of the US Dietary Guidelines, 173 nutrition scientists signed a letter demanding retraction. Retraction requests are conventionally reserved for fraudulent data. When asked, not one signatory could name a specific error. One admitted he hadn't read the article. Another said it shouldn't have been published because it wasn't peer-reviewed — it was.

The criticism landed on the author, not the work. She's a journalist, not a scientist. She has a book to sell. David Katz of Yale — himself the author of four diet books — called Teicholz "shockingly unprofessional" and described "unanimous revulsion" in rooms of senior nutritionists at the mention of her name. He cited no examples. She was invited to a panel discussion at a national food policy conference, then disinvited after fellow panelists refused to share a platform with her. She was replaced by the CEO of the Alliance for Potato Research and Education.

This is the same mechanism used against Yudkin: attack the person, not the finding. What's changed is that the monopoly on authority is gone. Lustig's 2009 YouTube lecture has been viewed more than six million times. The internet broke the establishment's ability to define who counts as credible — and in a field with a track record of getting it wrong, that's hard to argue is bad.

Source claim: The nutrition establishment responds to heterodox findings with ad hominem attacks and retraction demands rather than engagement with evidence — the same suppression mechanism used against Yudkin is now deployed against Teicholz.
