The Gluten-Free Craze Is a Symptom of a Bigger Problem With Medicine

Doctors can help stop the spread of fake food news.

When journalist and physician James Hamblin investigated the world of gluten-free products, he found a $23 billion industry of “detox courses,” custom blood tests, and specially formulated foods. What he didn’t find was medical evidence that avoiding gluten is good for people who don’t have celiac disease. In fact, the many gastroenterologists that he interviewed agreed that gluten-free diets can actually be less healthy than those that contain gluten. So how did the craze take hold if there’s essentially no science to back it up?

“If Jenny McCarthy writes a book then doctors have to play catch up, trying to undo the damage she’s done during office visits.”

That’s one question that Hamblin attempts to answer in his new book, If Our Bodies Could Talk: A Guide to Operating and Maintaining a Human Body, and during our interview on Mother Jones‘ food politics podcast Bite. Hamblin, also a senior editor at the Atlantic, argues that the gluten-free trend—along with many other health fads—is “a symptom of a real problem within the medical establishment.” Up until a few decades ago, he explains, patients regarded their doctors as the ultimate health authorities—they trusted physicians to make recommendations based on the latest science. But “as the ethical principle of patient autonomy has gained recognition, medicine has lurched toward patient-doctor collaboration,” Hamblin writes.

In some ways, that’s a good thing: Under the older, more paternalistic system, people often felt ignored or dismissed by their doctors. But Hamblin spoke to a Vanderbilt University gastroenterologist named Douglas Seidner who pointed out a problem with the collaborative model. His patients, he told Hamblin, come in already convinced that gluten is making them sick. Often, they request tests they’ve read about in books by health gurus. If Seidner declines to order the tests, “patients may go to another (possibly an ‘alternative’) practitioner who will tell patients what they want to hear, give them the label they seek, order the tests they want.”

So how can people avoid falling prey to fraudulent health gurus? Physicians, Hamblin believes, must change how they communicate with patients. Simply conveying information during an office visit isn’t enough anymore. “If Jenny McCarthy writes a book then doctors have to play catch up, trying to undo the damage she’s done during office visits,” he says. “Doctors are realizing that they can’t be above being on Twitter, being on the internet—they have to get out ahead” by publishing accurate information online, in books, and in the media.

“Doctors are realizing that they can’t be above being on Twitter, being on the internet.”

Physicians can also help people put the information they’ve found in context, pointing patients toward more accurate sources if necessary. “Doctors shouldn’t reflexively get angry at people who do their own research on the internet and think they have their own case solved,” he says. Instead, they can “act like filters,” teaching how to distinguish medical information from pseudoscience.

On this week’s episode of the Mother Jones food politics podcast Bite, I talked to Hamblin about the gluten-free boondoggle, how multivitamins can make people less healthy, and more reasons why people are so susceptible to health quackery. You can listen to the episode above—the interview with Hamblin starts at 06:23.

The more we thought about how MoJo's journalism can have the most impact heading into the 2020 election, the more we realized that so many of today's stories come down to corruption: democracy and the rule of law being undermined by the wealthy and powerful for their own gain.

So we're launching a new Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption. We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We'll publish what we find as a major series in the summer of 2020, including a special issue of our magazine, a dedicated online portal, and video and podcast series so it doesn't get lost in the daily deluge of breaking news.

It's unlike anything we've done before and we've got seed funding to get started, but we're asking readers to help crowdfund this new beat with an additional $500,000 so we can go even bigger. You can read why we're taking this approach and what we want to accomplish in "Corruption Isn't Just Another Scandal. It's the Rot Beneath All of Them," and if you like how it sounds, please help fund it with a tax-deductible donation today.
