How the Sugar Industry Shifted Blame to Fat

leave a comment »

This still makes my blood boil. Anahad O’Connor reported in the NY Times a couple of years ago:

The sugar industry paid scientists in the 1960s to play down the link between sugar and heart disease and promote saturated fat as the culprit instead, newly released historical documents show.

The internal sugar industry documents, recently discovered by a researcher at the University of California, San Francisco, and published Monday in JAMA Internal Medicine, suggest that five decades of research into the role of nutrition and heart disease, including many of today’s dietary recommendations, may have been largely shaped by the sugar industry.

“They were able to derail the discussion about sugar for decades,” said Stanton Glantz, a professor of medicine at U.C.S.F. and an author of the JAMA Internal Medicine paper.

The documents show that a trade group called the Sugar Research Foundation, known today as the Sugar Association, paid three Harvard scientists the equivalent of about $50,000 in today’s dollars to publish a 1967 review of research on sugar, fat and heart disease. The studies used in the review were handpicked by the sugar group, and the article, which was published in the prestigious New England Journal of Medicine, minimized the link between sugar and heart health and cast aspersions on the role of saturated fat.

Even though the influence-peddling revealed in the documents dates back nearly 50 years, more recent reports show that the food industry has continued to influence nutrition science.

Last year, an article in The New York Times revealed that Coca-Cola, the world’s largest producer of sugary beverages, had provided millions of dollars in funding to researchers who sought to play down the link between sugary drinks and obesity. In June, The Associated Press reported that candy makers were funding studies that claimed that children who eat candy tend to weigh less than those who do not.

The Harvard scientists and the sugar executives with whom they collaborated are no longer alive. One of the scientists who was paid by the sugar industry was D. Mark Hegsted, who went on to become the head of nutrition at the United States Department of Agriculture, where in 1977 he helped draft the forerunner to the federal government’s dietary guidelines. Another was Dr. Fredrick J. Stare, the chairman of Harvard’s nutrition department.

In a statement responding to the JAMA journal report, the Sugar Association said that the 1967 review was published at a time when medical journals did not typically require researchers to disclose funding sources. The New England Journal of Medicine did not begin to require financial disclosures until 1984.

The industry “should have exercised greater transparency in all of its research activities,” the Sugar Association statement said. Even so, it defended industry-funded research as playing an important and informative role in scientific debate. It said that several decades of research had concluded that sugar “does not have a unique role in heart disease.”

The revelations are important because the debate about the relative harms of sugar and saturated fat continues today, Dr. Glantz said. For many decades, health officials encouraged Americans to reduce their fat intake, which led many people to consume low-fat, high-sugar foods that some experts now blame for fueling the obesity crisis.

“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,” he said.

Dr. Hegsted used his research to influence the government’s dietary recommendations, which emphasized saturated fat as a driver of heart disease while largely characterizing sugar as empty calories linked to tooth decay. Today, the saturated fat warnings remain a cornerstone of the government’s dietary guidelines, though in recent years the American Heart Association, the World Health Organization and other health authorities have also begun to warn that too much added sugar may increase cardiovascular disease risk.

Marion Nestle, a professor of nutrition, food studies and public health at New York University, wrote an editorial accompanying the new paper in which she said the documents provided “compelling evidence” that the sugar industry had initiated research “expressly to exonerate sugar as a major risk factor for coronary heart disease.”

“I think it’s appalling,” she said. “You just never see examples that are this blatant.”

Dr. Walter Willett, chairman of the nutrition department at the Harvard T. H. Chan School of Public Health, said that academic conflict-of-interest rules had changed significantly since the 1960s, but that the industry papers were a reminder of “why research should be supported by public funding rather than depending on industry funding.”

Dr. Willett said the researchers had limited data to assess the relative risks of sugar and fat. “Given the data that we have today, we have shown the refined carbohydrates and especially sugar-sweetened beverages are risk factors for cardiovascular disease, but that the type of dietary fat is also very important,” he said.

The JAMA Internal Medicine paper relied on thousands of pages of correspondence and other documents that Cristin E. Kearns, a postdoctoral fellow at U.C.S.F., discovered in archives at Harvard, the University of Illinois and other libraries.

The documents show that in 1964, John Hickson, a top sugar industry executive, discussed a plan with others in the industry to shift public opinion “through our research and information and legislative programs.”

At the time, studies had begun pointing to a relationship between high-sugar diets and the country’s high rates of heart disease. At the same time, other scientists, including the prominent Minnesota physiologist Ancel Keys, were investigating a competing theory that it was saturated fat and dietary cholesterol that posed the biggest risk for heart disease.

Mr. Hickson proposed countering the alarming findings on sugar with industry-funded research. “Then we can publish the data and refute our detractors,” he wrote.

In 1965, Mr. Hickson enlisted the Harvard researchers to write a review that would debunk the anti-sugar studies. He paid them a total of $6,500, the equivalent of $49,000 today. Mr. Hickson selected the papers for them to review and made it clear he wanted the result to favor sugar.

Harvard’s Dr. Hegsted reassured the sugar executives. “We are well aware of your particular interest,” he wrote, “and will cover this as well as we can.”

As they worked on their review, the Harvard researchers shared and discussed early drafts with Mr. Hickson, who responded that he was pleased with what they were writing. The Harvard scientists had dismissed the data on sugar as weak and given far more credence to the data implicating saturated fat.

“Let me assure you this is quite what we had in mind, and we look forward to its appearance in print,” Mr. Hickson wrote. . .

Nordic walking

leave a comment »

I just learned about Nordic walking recently, and I’m almost obsessed by it. One reason is that I used a Nordic Track ski exerciser for years and I liked it a lot. It provides an excellent workout—but it does require significant apartment space. But I knew I had to do something: my life has become almost totally sedentary, each day going by with me in my chair—reading, writing, watching movies. There’s an unsettling unanimity in medical and scientific judgments that such a lifestyle is unhealthful to the point of shortening one’s life, and since I enjoy my life, I’d rather go in the other direction. That meant finding an exercise to do daily.

The idea of making a necessary task enjoyable has always appealed to me (cf. my guide to DE shaving), and exercise is definitely something I (and you) should do—but if it’s not actually enjoyable, that makes doing it difficult. Rather than being pulled to it, one must push himself to do it. That requires willpower, and I like to conserve that resource for when it is really needed. If I find an exercise that is enjoyable and that attracts me, I won’t need to use up some of my willpower. Besides being enjoyable, an ideal exercise for me is something i can do on my own without requiring other people (team sports or even just, say, a tennis opponent) or going to a special facility (a court or a gym or fitness club or playing field or the like) or having to be some particular place at a scheduled time.

Bicycling was enjoyable, but I don’t plan to be biking. I do plan to walk (and have already started), and the more I learn about Nordic walking, the more I think it will make the walk more enjoyable (and also better as exercise, engaging the muscles of the upper body).

So I’ve added a bunch of links to a new link category at the right: “Nordic walking”. The links (here presented in logical rather than alphabetic order):

There are health benefits in using the poles (and see also this detailed research study), but a primary benefit I want is to make me look forward to going for a walk.

Poles come in three types:

• one-section (not adjustable, so you have to buy the right-length pole for you),
• two-section (adjustable, so the same poles can be used by people of different height; also useful in determining the ideal length for you), and
• three-section (same idea as two section but can be collapsed smaller for packing in a suitcase).

The ideal (IMO) is the one-section pole, and eventually I think I’ll get a pair from Exel, the Finnish company that started Nordic walking in the first place. The two-section pole seems better than the three-section in terms of vibration and strength, the three-section pole’s only advantage being its shorter length when collapsed. (Three-section poles are often named “Traveler” or the like.)

The foot of the pole is a carbide spike for walking on grass or dirt and a rubber paw for walking on hard surfaces like pavement. Exel has an interesting variation: a one-piece all-terrain tip — see video above.

Update: My Komperdell Nordic walking poles just arrived!

Update 2: What I learned in my first formal lesson. As is typical of self-taught practitioners, I fell into some common (and easily corrected) errors. And since Nordic walking, like (for example) rowing and swimming, consists of continual repetition of the same actions, any flaws in technique are multiplied by the number of repetitions and thus their cost grows over time.

The video below shows the basics of using the poles, and more instructional videos are on this page.

The Trump administration used threats at a world forum to try to block a measure … that endorsed breast-feeding. Health officials were stunned.

leave a comment »

Trump continues to be a bull in a china shop. Andrew Jacobs reports in the NY Times:

A resolution to encourage breast-feeding was expected to be approved quickly and easily by the hundreds of government delegates who gathered this spring in Geneva for the United Nations-affiliated World Health Assembly.

Based on decades of research, the resolution says that mother’s milk is healthiest for children and countries should strive to limit the inaccurate or misleading marketing of breast milk substitutes.

Then the United States delegation, embracing the interests of infant formula manufacturers, upended the deliberations.

American officials sought to water down the resolution by removing language that called on governments to “protect, promote and support breast-feeding” and another passage that called on policymakers to restrict the promotion of food products that many experts say can have deleterious effects on young children.

When that failed, they turned to threats, according to diplomats and government officials who took part in the discussions. Ecuador, which had planned to introduce the measure, was the first to find itself in the cross hairs.

The Americans were blunt: If Ecuador refused to drop the resolution, Washington would unleash punishing trade measures and withdraw crucial military aid. The Ecuadorean government quickly acquiesced.

The showdown over the issue was recounted by more than a dozen participants from several countries, many of whom requested anonymity because they feared retaliation from the United States.

Health advocates scrambled to find another sponsor for the resolution, but at least a dozen countries, most of them poor nations in Africa and Latin America, backed off, citing fears of retaliation, according to officials from Uruguay, Mexico and the United States.

“We were astonished, appalled and also saddened,” said Patti Rundall, the policy director of the British advocacy group Baby Milk Action, who has attended meetings of the assembly, the decision-making body of the World Health Organization, since the late 1980s.

“What happened was tantamount to blackmail, with the U.S. holding the world hostage and trying to overturn nearly 40 years of consensus on best way to protect infant and young child health,” she said.

In the end, the Americans’ efforts were mostly unsuccessful. It was the Russians who ultimately stepped in to introduce the measure — and the Americans did not threaten them. . .

Continue reading. There’s much more. And it’s disgusting.

Odd to feel thankful about how Trump is afraid to cross Russia.

Kevin Drum comments: “You have to give them credit: big business gets what they pay for when they buy a Republican administration. But even big business can’t overcome Trump’s love for Vladimir Putin.”

Chiseled Face synthetic, Strop Shoppe Vivace, iKon 102, and Paul Sebastian

leave a comment »

Very satisfying shave this morning: the two-day-stubble shave. The very nice brush I bought a few years back from Chiseled Face Groomatorium made a fine lather from Strop Shoppe’s Vivace, and the 102 is unparalleled in comfortable and efficient stubble removal. A splash of Paul Sebastian aftershave, one of my favorites (and sold on Amazon, FWIW) and the day is launched.

I’ve been looking at Exel Nordic walking poles—those of a fixed length. Have to order from the UK, though.
