Sugar – sugar from fruit – good. Sugar in candy and processed foods – poison.
50 Years Ago, Sugar Industry Quietly Paid Scientists To Point Blame At Fat

In the 1960s, the sugar industry funded research that downplayed the risks of sugar and highlighted the hazards of fat, according to a newly published article in JAMA Internal Medicine.
The article draws on internal documents to show that an industry group called the Sugar Research Foundation wanted to “refute” concerns about sugar’s possible role in heart disease. The SRF then sponsored research by Harvard scientists that did just that. The result was published in the New England Journal of Medicinein 1967, with no disclosure of the sugar industry funding.
The sugar-funded project in question was a literature review, examining a variety of studies and experiments. It suggested there were major problems with all the studies that implicated sugar, and concluded that cutting fat out of American diets was the best way to address coronary heart disease.
The authors of the new article say that for the past five decades, the sugar industry has been attempting to influence the scientific debate over the relative risks of sugar and fat.
“It was a very smart thing the sugar industry did, because review papers, especially if you get them published in a very prominent journal, tend to shape the overall scientific discussion,” co-author Stanton Glantz told The New York Times.
In the article, published Monday, authors Glantz, Cristin Kearns and Laura Schmidt aren’t trying make the case for a link between sugar and coronary heart disease. Their interest is in the process. They say the documents reveal the sugar industry attempting to influence scientific inquiry and debate.
The researchers note that they worked under some limitations — “We could not interview key actors involved in this historical episode because they have died,” they write. Other organizations were also advocating concerns about fat, they note.
There’s no evidence that the SRF directly edited the manuscript published by the Harvard scientists in 1967, but there is “circumstantial” evidence that the interests of the sugar lobby shaped the conclusions of the review, the researchers say.
For one thing, there’s motivation and intent. In 1954, the researchers note, the president of the SRF gave a speech describing a great business opportunity.
If Americans could be persuaded to eat a lower-fat diet — for the sake of their health — they would need to replace that fat with something else. America’s per capita sugar consumption could go up by a third.
But in the ’60s, the SRF became aware of “flowing reports that sugar is a less desirable dietary source of calories than other carbohydrates,” as John Hickson, SRF vice president and director of research, put it in one document.
He recommended that the industry fund its own studies — “Then we can publish the data and refute our detractors.”
The next year, after several scientific articles were published suggesting a link between sucrose and coronary heart disease, the SRF approved the literature-review project. It wound up paying approximately $50,000 in today’s dollars for the research.
One of the researchers was the chairman of Harvard’s Public Health Nutrition Department — and an ad hoc member of SRF’s board.
“A different standard” for different studies
Glantz, Kearns and Schmidt say many of the articles examined in the review were hand-selected by SRF, and it was implied that the sugar industry would expect them to be critiqued.
In a letter, SRF’s Hickson said that the organization’s “particular interest” was in evaluating studies focused on “carbohydrates in the form of sucrose.”
“We are well aware,” one of the scientists replied, “and will cover this as well as we can.”
The project wound up taking longer than expected, because more and more studies were being released that suggested sugar might be linked to coronary heart disease. But it was finally published in 1967.
Hickson was certainly happy with the result: “Let me assure you this is quite what we had in mind and we look forward to its appearance in print,” he told one of the scientists.
The review minimized the significance of research that suggested sugar could play a role in coronary heart disease. In some cases the scientists alleged investigator incompetence or flawed methodology.
“It is always appropriate to question the validity of individual studies,” Kearns told Bloomberg via email. But, she says, “the authors applied a different standard” to different studies — looking very critically at research that implicated sugar, and ignoring problems with studies that found dangers in fat.
Epidemiological studies of sugar consumption — which look at patterns of health and disease in the real world — were dismissed for having too many possible factors getting in the way. Experimental studies were dismissed for being too dissimilar to real life.
One study that found a health benefit when people ate less sugar and more vegetables was dismissed because that dietary change was not feasible.
Another study, in which rats were given a diet low in fat and high in sugar, was rejected because “such diets are rarely consumed by man.”
The Harvard researchers then turned to studies that examined risks of fat — which included the same kind of epidemiological studies they had dismissed when it came to sugar.
Citing “few study characteristics and no quantitative results,” as Kearns, Glantz and Schmidt put it, they concluded that cutting out fat was “no doubt” the best dietary intervention to prevent coronary heart disease.
Sugar lobby: “Transparency standards were not the norm”
In a statement, the Sugar Association — which evolved out of the SRF — said it is challenging to comment on events from so long ago.
“We acknowledge that the Sugar Research Foundation should have exercised greater transparency in all of its research activities, however, when the studies in question were published funding disclosures and transparency standards were not the norm they are today,” the association said.
“Generally speaking, it is not only unfortunate but a disservice that industry-funded research is branded as tainted,” the statement continues. “What is often missing from the dialogue is that industry-funded research has been informative in addressing key issues.”
The documents in question are five decades old, but the larger issue is of the moment, as Marion Nestle notes in a commentary in the same issue of JAMA Internal Medicine:
“Is it really true that food companies deliberately set out to manipulate research in their favor? Yes, it is, and the practice continues. In 2015, the New York Times obtained emails revealing Coca-Cola’s cozy relationships with sponsored researcherswho were conducting studies aimed at minimizing the effects of sugary drinks on obesity. Even more recently, the Associated Press obtained emails showing how a candy trade association funded and influenced studies to show that children who eat sweets have healthier body weights than those who do not.”
As for the article authors who dug into the documents around this funding, they offer two suggestions for the future.
“Policymaking committees should consider giving less weight to food industry-funded studies,” they write.
They also call for new research into any ties between added sugars and coronary heart disease.
What Happened When a Scientist Denounced Sugar in the 70s
By Niki Laskaris at Brandeis
John Yudkin, British physiologist and nutritionist, and the founding Professor of the Department of Nutrition at Queen Elizabeth College, London tried to spare us a lot of time and energy back in the Seventies with his prognostic work Pure, White and Deadly, 1972. The book, which was out-of-print until just a few years ago (retrofitted by childhood obesity specialist Dr Robert Lustig M.D.), exposed sugar as a menace to health far before society accepted the idea as true. His theory, instead of making him a wellness demigod, made him an outcast and cost him his job.
How?
In the 60s, due to an alarming rise in heart disease levels, nutritionists in university laboratories all over America and Western Europe were hustling to figure out the reason for this increase. By 1970, there were 520 deaths per 100,000 per year in England and Wales caused by coronary heart disease and 700 per 100,000 in America. Eventually, an agreement was reached: the cause was saturated fat.
By way of this announcement, the food industry saw an opportunity: Market research proved there was a great deal of public enthusiasm for “healthy” and low-fat foods. By the beginning of the 70s, supermarket shelves were brimming with low-fat food products.
John Yudkin disagreed; he asserted that there was a much more distinct relationship between the rise in heart disease and a rise in the consumption of sugar. Rodents, chickens, rabbits, pigs and students fed sugar and carbohydrates, he said, on every occasion showed increased blood levels of triglycerides (a technical label for fat), which was then, as now, regarded as a risk factor for heart disease. Sugar also heightened insulin levels, connecting it directly with type 2 diabetes.The food industry as a whole was displeased with this premise.
Why?
When developing their low-fat products, manufacturers needed a replacement for fat which would enrich the taste of the food. They chose sugar. The contemporary “healthy” foods were low-fat yet contained an abundance of sugar, and so Yudkin’s discovery was a threat to an entire sector of the economy.
What happened?
Consequently there was a collaborative campaign by the food industry and several scientists to slander Yudkin’s work. The British Sugar Bureau issued a press release dismissing Yudkin’s claims as “emotional assertions” and the World Sugar Research Organization called his book “science fiction.”
He was uninvited to international conferences and others that he organized were cancelled after pressures from sponsors like Coca-Cola. By the end of the 70s, he had been so disgraced that few scientists were courageous enough to publish anything negative about sugar for fear of being so attacked. In consequence, the low-fat industry, with its products awash with sugar, prospered.
However, in the 80s, and years later, multiple discoveries demonstrated the truth of Yudkin’s theories. Researchers learned fructose, one of the two main carbohydrates in refined sugar, is largely metabolised by the liver; while glucose (present in starchy food like bread and potatoes) is metabolised by all cells. This means immoderate consumption of fructose puts extra demands on the liver, which then turns fructose to fat.
Now, Robert Lustig, professor of pediatric endocrinology at the University of California, acclaims Yudkin’s work as prophetic: “Everything this man said in 1972 was the God’s honest truth and if you want to read a true prophecy you find this book…I’m telling you every single thing this guy said has come to pass. I’m in awe… Science took a disastrous detour in ignoring Yudkin. It was to the detriment of the health of millions.”
Namaste,
