The risk of food-related allergies has been greatly overblown, according to journalist Meredith Broussard (who’s had food allergies herself). Her article in the January issue of Harper’s magazine is "Everyone’s Gone Nuts."

Note: On Thurs., Jan. 31 at 12:40, we're doing a follow-up segment addressing listeners' concerns about Ms. Broussard's interview about food allergies. Leonard will speak with Dr. Hugh Sampson of Mt. Sinai School of Medicine; he's Chief of Pediatric Allergy & Immunology and Director of the Jaffe Food Allergy Institute.
