THE SUGAR RESEARCH PAPERS

THE CLAIM

That the sugar industry secretly funded scientific reviews designed to shift blame for heart disease from sugar to dietary fat, concealed its role, and thereby influenced public health policy for decades.

THE THEORY, AS ITS PROPONENTS TELL IT

The evidence here is the industry's own correspondence, which is why this file is graded the way it is.

In 1965 the Sugar Research Foundation paid three Harvard scientists to write a review of the literature on diet and coronary heart disease. The internal designation was Project 226. The correspondence shows the foundation set the objective, supplied articles it wanted included, reviewed drafts, and was assured by the lead author that it would be covered.

The resulting two-part review appeared in the New England Journal of Medicine in 1967. It minimised the evidence implicating sucrose and directed attention to dietary fat and cholesterol. The journal did not require disclosure of funding at the time, and none was made.

The argument proponents draw is about durability. Dietary guidance in several countries subsequently emphasised fat reduction, the food industry reformulated toward low-fat products that were frequently higher in sugar, and the review's authors included a man who went on to become head of nutrition at the United States Department of Agriculture. Whether the review caused that trajectory or rode it is the genuine open question.

WHAT IS KNOWN

The documents are real and were published in JAMA Internal Medicine in 2016 by Cristin Kearns, Laura Schmidt and Stanton Glantz, having been found in institutional archives.

The correspondence establishes the funding, the industry's involvement in scope and review, and the absence of disclosure. It does not contain an instruction to reach a particular conclusion in so many words.

Disclosure norms changed substantially afterwards. The absence of a declaration in 1967 was legal and common, which is context rather than exculpation.

The scientific position has since moved. Sugar's role in metabolic disease is now taken far more seriously, and several national dietary guidelines have been revised accordingly.

EVIDENCE FOR

• The industry's own letters, setting the objective and reviewing drafts before publication.
• The undisclosed funding of a review in a leading medical journal.
• The 2016 peer-reviewed analysis presenting the documents, which the industry has not disputed.
• The subsequent career of one of the authors at the agency writing federal dietary guidance.

EVIDENCE AGAINST (THE CAUSAL CLAIM)

• No document instructs the authors to reach a conclusion. Industry involvement in framing is documented; fabrication is not.
• The fat hypothesis had substantial independent scientific support at the time, from researchers with no industry funding, so the review was not creating a position out of nothing.
• Attributing fifty years of dietary policy to one funded review overstates what any single publication does, and the historical record is messier than the popular version.

ASSESSMENT

Confirmed as to the conduct, overstated in most retellings as to the consequence. The industry paid for a review, shaped its scope, saw the drafts, and did not disclose. That is established from its own filing cabinet and it is exactly the pattern in OSA-017 and OSA-106, arriving by the same route and found the same way, which is to say by somebody reading old boxes. What this office will not endorse is the claim that this one review redirected global nutrition. The honest version is smaller and still damning: the scientific literature was purchasable, the purchase was invisible, and it stayed invisible for half a century.

WHAT WOULD CHANGE THE GRADE

• CONFIRMED as to conduct, from the industry's own correspondence: the Sugar Research Foundation commissioned the review, set its objective, supplied material, saw drafts, and the funding was not disclosed.
• Not established, and routinely overstated: that this one review redirected fifty years of dietary policy. The fat hypothesis had substantial independent support at the time, and no document instructs the authors to reach a conclusion.
• What would sharpen it: the rest of the foundation's project files. Project 226 was found in one executive's papers, and there is no reason to think that collection is complete.
