BBC: Hope over peanut allergy 'cure'
A team from Cambridge's Addenbrooke's Hospital exposed four children to peanuts over a six-month period, gradually building up their tolerance.
By the end the children were eating the equivalent of five peanuts a day.
It is the first time a food allergy has been desensitised in such a way, although a longer-term follow up is now needed to confirm the findings.
