cold fjord writes: "The BBC reports, 'Peanuts are the most common cause of fatal allergic reactions to food. There is no treatment so the only option for patients is to avoid them completely, leading to a lifetime of checking every food label before a meal. The trial ... tried to train the children's immune system to tolerate peanut. Every day they were given a peanut protein powder — starting off on a dose equivalent to a 70th of a peanut. Once a fortnight the dose was increased while the children were in hospital and then they continued taking the higher dose at home. The majority of patients learned to tolerate the peanut. ... Dr Andrew Clark, told the BBC: "It really transformed their lives dramatically, this really comes across during the trial. ... Dr Pamela Ewan added ... further studies would be needed and that people should not try this on their own as this "should only be done by medical professionals in specialist settings."' The story also notes, 'The findings, published in the Lancet, suggest 84% of allergic children could eat the equivalent of five peanuts a day after six months.'"
