Sugar industry sought to sugarcoat causes of heart disease
Payments revealed to authors of influential 1967 report touting fat and cholesterol as problems

Using records unearthed from library storage vaults, researchers recently revealed that the sugar industry paid nutrition experts from Harvard University to downplay studies linking sugar and heart disease. Although the incident happened in the 1960s, it appears to have helped redirect the scientific narrative for decades.
The documents — which include correspondence, symposium programs and annual reports — show that the Sugar Research Foundation (as it was named at the time) paid professors who wrote a two-part review in 1967 in the New England Journal of Medicine. That report was highly skeptical of the evidence linking sugar to cardiovascular problems but accepting of the role of fat. The now-deceased professors’ overall conclusion left “no doubt” that reducing the risk of heart disease was a matter of reducing saturated fat and cholesterol, according to researchers from the University of California, San Francisco, who published their report online September 12 in JAMA Internal Medicine.
“Why does it matter today? The sugar industry helped deflect the way the research was developing,” says study coauthor Cristin Kearns, a dentist at UCSF’s Institute for Health Policy Studies. The Harvard team’s scientific favoritism had a role in directing research and policy attention toward fat and cholesterol. And in fact, the first dietary guidelines published by the federal government in 1980 said there was no convincing evidence that sugar causes heart disease, stating “the major health hazard from too much sugar is tooth decay.”
