From the New Yorker, this is the latest in the demythologizing of the "gluten-free" wave. I have nothing against gluten free, but it doesn't help that there is so much alarmist misunderstanding.
Just after Labor Day, the Gluten and Allergen Free Expo stopped for a weekend at the Meadowlands Exposition Center. Each year, the event wends its way across the country like a travelling medicine show, billing itself as the largest display of gluten-free products in the United States. Banners hung from the rafters, with welcoming messages like “Plantain Flour Is the New Kale.” Plantain flour contains no gluten, and neither did anything else at the exposition (including kale). There were gluten-free chips, gluten-free dips, gluten-free soups, and gluten-free stews; there were gluten-free breads, croutons, pretzels, and beer. There was gluten-free artisanal fusilli and penne from Italy, and gluten-free artisanal fusilli and penne from the United States. Dozens of companies had set up tables, offering samples of gluten-free cheese sticks, fish sticks, bread sticks, and soy sticks. One man passed out packets of bread crumbs, made by “master bakers,” that were certified as gluten-free, G.M.O.-free, and kosher. There was even gluten-free dog food. Read more here.
