This is good news for peanut lovers!
The idea of a fear of food being a self-fulfilling prophecy is an interesting one, and it seems to make sense to me. We have to be exposed to germs to build up our immune system so it certainly seems to follow that early exposure to potential allergens could also help to establish tolerance.
The new study suggests that if a child has consumed peanut snacks within the first 11 months of life, then at the age of five they can afford to stop eating the food entirely for a year, and maintain no allergy. Lead author Prof Gideon Lack said: "[The research] clearly demonstrates that the majority of infants did in fact remain protected and that the protection was long-lasting." He said that part of the problem was that people lived in a "culture of food fear". "I believe that this fear of food allergy has become a self-fulfilling prophecy, because the food is excluded from the diet and, as a result, the child fails to develop tolerance," he told the BBC News website.
