NY Times’ Sugar Bombshell

April 18th, 2011 · 10 Comments · Posted in food news

Science writer Gary Taubes

We may look back on this week as the moment when public opinion finally turned against the idea that fat is what makes us ill and embraced the emerging science implicating sugar as the nation’s number one threat to good health.

In Sunday’s New York Time’s Magazine, science writer Gary Taubes makes the case that sugar–not fat–is the agent behind our most pressing health problems, including obesity and the various degenerative ailments associated with “metabolic syndrome,” including diabetes, hypertension and coronary artery disease. If true, this would overturn more than 30 years of ill-conceived nutrition and health policy in this country, recognizing what a growing number of medical researchers have already concluded: fat is not the problem, carbs are. The reason for America’s shocking level of obesity and related health issues lies with our addiction to processed, carbohydrate-rich foods, starches, and especially sugar.

The implications for those of us primarily concerned with children’s health are clear: kids should not be drinking sodas or sugary flavored milks. They need to stop indulging in all kinds of snack foods and desserts that now play such a prominent role in children’s eating habits. School menus should be sugar-free–and that goes for chocolate milk, too.

The most vocal of medical authorities now blaming sugar is Robert Lustig, a specialist in childhood obesity and pediatric hormone disorders at the University of California, Berkeley. We’ve written about Lustig and quoted him here before. Taubes describes his 2009 lecuture called “Sugar: The Bitter Truth,” which at last count had been viewed 973,123 times at YouTube and has been increasing viewership at a rate of some 50,000 per month.

In his 90-minute talk, Lustig outlines in some detail how the fructose contained in either sugar or high-fructose corn syrup is treated by the body as a toxin; how, unlike glucose, the sugar derived from other carbohydrates such as bread and potatoes, fructose is converted into fat in the liver, triggering not just “metabolic syndrome,” but, in Taubes’ view, many common cancers as well. Lustig blames sugar for a worldwide epidemic of fatty liver disease in children.

Most importantly, Lustig insists that the obesity epidemic we are so concerned about is not just about too many calories, but eating the wrong kinds of calories–specifically, too much sugar. Sugar represents not just empty calories. “It’s not about the calories,” Lustig says. “It has nothing to do with the calories. It’s a poison by itself.” Lustig says the reason Americans are consuming more calories is because their appetite suppression mechanisms are disrupted by eating too much sugar, especially from soda and other sweetened beverages.

“In animals, or at least in laboratory rats and mice, it’s clear that if the fructose hits the liver in sufficient quantity and with sufficient speed, the liver will convert much of it to fat,” Taubes writes. “This apparently induces a condition known as insulin resistance, which is now considered the fundamental problem in obesity, and the underlying defect in heart disease and in the type of diabetes, type 2, that is common to obese and overweight individuals. It might also be the underlying defect in many cancers.”

How much sugar do you have to eat before it becomes toxic? That’s the $64,000 question. The last time the federal government looked at this, in a 1986 Food and Drug Administration report, it was estimated sugar did not pose a danger at what was then the current level of consumption: 40 pounds of sugar per person per year of “added sugar,” meaning in addition to what the normal person would get from eating fruits and vegetables. That’s 200 calories per day of sugar, Taubes says, or less than the amount in a can and a half of Coca-Colar or two cups of apple juice.

“But 40 pounds per year happened to be 35 pounds less than what Department of Agriculture analysts said we were consuming at the time–75 pounds per person per year–and the USDA estimates are typically considered to be the most reliable,” Taubes writes. “By the early 2000s, according to the USDA, we had increased our consumption to more than 90 pounds per person per year.”

Obesity rates in this country correlate neatly with increasing consumption of sugar, and especially high-fructose corn syrup, which contains more fructose than table sugar as is not only sweeter but cheaper than cane sugar. Now researchers are finding that many forms of virulent cancer thrive on the insulin the body produces in response to sugar. Obesity and diabetes go hand in hand. Likewise, people who are obese or diabetic are more likely to develop some form of cancer.

That has some medical researchers swearing off sugar in their personal diets. “I have eliminated refined sugar from my diet and eat as little as I possbly can,” says researcher Craig Thompson, president of Memorial Sloan-Kettering Cancer Center in New York, “because I believe ultimately it’s something I can do to decrease my risk of cancer.”

Lewis Cantley, director of the Cancer Center at Beth Israel Deaconness Medical Center at Harvard Medical School says, simply: “Sugar scares me.”

Unfortunately, little funding on the dangers of sugar has been forthcoming from the federal government. The National Institutes of Health is funding a few small studies. Taubes suggests these need to be bigger and of longer duration. But even though the current science is not as conclusive as Robert Lustig believes it to be, Taubes says he’s convinced.

“Officially I’m not supposed to worry because the evidence isn’t conclusive, but I do.”

That’s good enough for me.

  • The Table of Promise

    I am over the moon about this article. It was [ublished online late last week and many of my friends were talking about.
    One thing I was confused about was that the article quoted our sugar consumption at 90 pounds per person per year. According to the USDA (http://www.usda.gov/factbook/chapter2.pdf) in the early 2000′s, corn sweeteners alone were consumed at a rate of almost 90 pounds per person per year and total added sweeteners including cane sugar and other natural sugars were consumed at over 150 pounds per person per year!!! Egads!!!

  • Ed Bruske

    So you think Taubes got it wrong?

  • The Table of Promise

    I assume that I have misunderstood the context in which Taubes was using the stat. I trust his knowledge of the subject. But even Nancy Appleton uses a figure of 150 pounds per person per year on her site and in her books. I provided the link to what the USDA says, the added sugar chart is on page 8. I don’t know??

    Fascinating piece. The article has definitely left many thinking. It definitely demands deeper research, and careful interpretation of the data. As we know, data can be misconstrued and applied for almost any purpose. Example: the Fat Head documentary who uses the not-fat argument to argue that fast food can actually help one to lose weight.

  • Ivana Kadija

    Taubes’ “Good Calories. Bad Calories.” should put your concerns to rest regarding misrepresented data with this guy, Belinda. It will however show you how much of the fat research over the past 50 years is in fact seriously mis-interpreting and, often, completely misrepresnting the actual data. The China Study comes to mind.

    Ed, thanks for summarizing so eloquently. Immensely useful for dissemination!

  • Ed Bruske

    You’re welcome, Ivana. Please disseminate!

    Do you remember a book published in the ’80′s that said much the same thing? It was not a dieting book. It put me off sugar in a big way. Very similar, explaining its toxicity to the body. I wish I still had my copy….

  • Ed Bruske

    You probably thinking of the book published by John Yudkin, “Sweet and Dangerous.”

    I have cut out much of the sugar in my diet…no cookies,cake ,soda etc. I do have one serving of gluten free waffle with cream cheese and hummus for breakfast. I am type 2 diabetic and was over 300 blood sugar…now around 139 ,the A1C test results. I was on meds at first,but had vision problems and stopped..told it was Macular Edema. I walk everyday and was never a big woman,but my weight was all in my middle.I had been low blood sugar for many years and then as I turned 68 was told I’m diabetic. I do take some supplements and they seem to help. Doctor recommended them.
