This recent article highlights a study that shows promising evidence that there might soon be a cure for peanut allergies. They gave 15 children tiny, but increasing doses of peanut flour and after one year, they were able to tolerate some peanuts without a reaction. I feel that this shows hope that all or most food allergies might be "cured" in the next few years. For children and adults with severe reactions, this is certainly good news!
