New report on food allergies: some folks think they have 'em when they don't

"Food allergies are real and can be life-threatening. It would be folly to dismiss them. But many people think they have them when they actually don't, according to a new report commissioned by the National Institute of Allergy and Infectious Diseases. And that says a lot about how we think about food." Gina Kolata in the New York Times. (via John Brockman)
