Peanut allergy affects more than 10 million people around the world and is the most common disorder linked to allergy deaths. But experts from the University of Cambridge might have a solution. The team took a pool of children and built up their tolerance to peanuts over a six-month period using oral immunotherapy. At the end of the trial period, 84% to 91% of participants could eat 800 mg of peanut protein on a daily basis—25 times more than they could eat before the study began. And if you or someone you know has a peanut allergy, you know how revolutionary that is. It means that parents of these kids can go out to a restaurant and not have to stress over whether the food’s cooked in peanut oil. But experts say the approach isn’t ready to be implemented far and wide, but it’s a significant step.
