Early Peanut Consumption May Prevent Allergy in Children MILWAUKEE, Wis -- October 30, 2008 -- Children who avoid peanuts in infancy and early childhood are 10 times more likely to develop peanut allergy as those who were exposed to peanuts early on, according to a study published in the November issue of The Journal of Allergy and Clinical Immunology. The new research casts doubt on government health recommendations that infants and new mothers avoid eating peanuts to prevent development of food allergy, although the American Academy of Allergy, Asthma & Immunology (AAAAI) cautions that the results shouldn't translate to changes in treatment just yet. For the study, researchers measured the incidence of peanut allergy in 8,600 Jewish school-age children in the UK and Israel. They compared these results with data on peanut consumption collected from mothers of infants aged 4 to 24 months. Prevalence of peanut allergy in the UK was estimated at 1.85% versus 0.17% in Israel (P < .001). At age 9 months, 69% of Israeli children were eating peanut compared with 10% of those in the UK. "The most obvious difference in the diet of infants in both populations occurs in the introduction of peanut," said lead author George Du Toit, MD, Children's Allergy Service, Evelina Children's Hospital, Guy's and St. Thomas' NHS Foundation Trust, King's College, London, United Kingdom. While researchers suggest these recommendations could be behind the increase in peanut allergy in these countries, they cautioned that further evidence is needed before those guidelines should be changed. "While this study's findings provide optimism for prevention of peanut allergy in the future, randomised, controlled trials are needed to verify that early introduction of peanut is indeed effective," said Jacqueline A. Pongracic, MD, AAAAI Adverse Reactions to Foods Committee, Milwaukee, Wisconsin. The Learning Early about Peanut Allergy (LEAP) study, a large randomised study in the UK, is currently testing the effects of early peanut exposure.
