Researchers in Cambridge believe they've made a breakthrough in developing a potential treatment for peanut allergy.
They carried out a trial where 100 children ate gradually increased doses of peanut protein each day.
After six months, 84% were able to eat up to five nuts a day without feeling ill. However, some experts are urging caution and say more research is needed.
