Two thirds of patients were able to eat the equivalent of five peanuts with no reaction by the end of the trial. People with the allergy should not try eating nuts at home, as doses started at a miniscule 0.8mg of peanut flour before working up to entire nuts.
Study author Hannah Hunter, from Guy’s and St Thomas’ NHS Trust, said: “Many participants who completed the trial told us that the treatment had been life-changing and they were no longer living in fear.” Advertisement Read more on allergies changed forever Mum's warning to all parents after snack left son unable to walk or talk NUTS NORMAL Woman's allergy flares up after sex with partner in 'first case' of its kind About one in every 200 adults in the UK – 0.5 per cent – has a nut allergy.
