AP In an interview with Harper's Bazaar earlier this month, Kylie Jenner shared that her daughter, Stormi, is allergic to nuts. Food allergies are a growing public health concern and affect 1 in 13 US children. Still, there's a pervasive stigma surrounding the condition, which is why advocates appreciate when famous people, like Jenner, open up about it. A number of other celebrities, including Britney Spears and Ariana Grande, have been vocal about how food allergies have impacted their lives.
