Ryan is severely allergic to peanuts. Like, hives-blossoming, throat-closing, get-me-epinephrine-now kind of allergic. But as part of a clinical trial at SickKids, which could change the course of allergy treatment, he now eats a tiny dose of the stuff every night. That’s because peanuts—the very food that could kill him—might also be the key to protecting him.
