Another corruption in science – by the sugar industry lobby

How the Sugar Lobby Skewed Health Research Archival documents reveal how the sugar industry secretly funded heart disease research by Harvard professors, Time, Alexandra Sifferlin @acsifferlin Sept. 12, 2016 The sugar industry has a long history of skewing nutrition science, a new report suggests. By combing through archival documents from the 1950s and 1960s, researchers from the University of California, San Francisco (UCSF), report that the sugar industry sponsored research that turned attention away from the sweetener’s link to heart disease and toward fat and cholesterol as the bigger culprits.

The documents the researchers reviewed in their report, published Monday in JAMA Internal Medicine, included correspondence between the Sugar Research Foundation (SRF) and nutrition professors at the Harvard School of Public Health. The letters discussed the SRF’s effort to respond to growing research linking sugar to coronary heart disease.

In 1954, SRF then-president Henry Hass gave a speech to the American Society of Sugar Beet Technologists that highlighted opportunities for the sugar industry to expand by encouraging people to adopt a low-fat diet. He said:

“Leading nutritionists are pointing out the chemical connection between [Americans’] high-fat diet and the formation of cholesterol which partly plugs our arteries and capillaries, restricts the flow of blood, and causes high blood pressure and heart trouble… if you put [the middle-aged man] on a low-fat diet, it takes just five days for the blood cholesterol to get down to where it should be… If the carbohydrate industries were to recapture this 20 percent of the calories in the US diet (the difference between the 40 percent which fat has and the 20 percent which it ought to have) and if sugar maintained its present share of the carbohydrate market, this change would mean an increase in the per capita consumption of sugar more than a third with a tremendous improvement in general health.”

What appears to have happened next were efforts by the SRF to increase skepticism over sugar’s link to heart troubles. In 1967, an SRF-funded report led by Harvard nutrition professors was published in the New England Journal of Medicine. The report reviewed the available evidence that linked various nutrients to heart disease and argued that epidemiological and animal studies that linked sugar with heart disease were limited, and suggested the available science wasn’t up to snuff. The review also highlighted studies that linked saturated fat to heart problems, without the same critiques. The review was published in the journal without disclosing the sugar industry’s funding or role in making the study happen in the first place. (Later, in 1984, the NEJM began requiring disclosure of conflicts of interest.)……….

It’s not the first time researchers have found links between sugar industry connections and nutrition science. The same team of UCSF researchers behind the new study previously used sugar industry documents to reveal how advocacy groups influenced federal cavity prevention recommendations.

“What struck me was that I thought the evidence the researchers summarized in the review was stronger and more consistent for a sugar effect [on coronary heart disease] than for a fat effect,” says study author Stanton Glantz of UCSF. “No matter how good the evidence was linking sugar to heart disease, there was something wrong with it. But for fat, the evidence was fine. They set up a false dichotomy.”

In an editorial published alongside new study, Marion Nestle, a professor in the Department of Nutrition and Food Studies at NYU, writes that the Harvard professors who conducted the review knew what the funders wanted and provided those findings. “Whether they did this deliberately, unconsciously, or because they genuinely believed saturated fat to be the greater threat is unknown,” Nestle writes. “But science is not supposed to work this way. The documents make this review seem more about public relations than science.”………http://time.com/4485710/sugar-industry-heart-disease-research/
