In a new study, researchers gave 85 kids a tiny amount of peanut protein, and then gradually ramped up that amount over the course of six months. At the end of that period, 88 percent of them could tolerate eating the equivalent of five peanuts without suffering an allergic reaction. And 58 percent could eat the equivalent of 10 peanuts without incident. The study consisted of two six-month periods; in the first span, half the kids were first given a placebo. None of them became tolerant to peanuts, showing the study results weren't due to the placebo effect.
