A major study has found exposure to peanuts in infancy seemed to help build tolerance - contrary to conventional thinking.

A pediatricians' group is recommending that infants at high risk of peanut allergies be given foods containing peanuts before they turn one.

The interim guidance is in response to a major allergy study published earlier this year which found that exposure to peanuts in infancy seemed to help build tolerance - contrary to conventional thinking.

Baby suitable foods used in the study included smooth peanut butter, peanut soup and finely ground peanuts mixed into yogurt and other foods.

The advice comes in a consensus statement that the American Academy of Pediatrics helped prepare and endorsed in June along with the American Academy of Allergy, Asthma & Immunology and several foreign allergy groups.

The academy is releasing the statement online Monday in the journal Pediatrics.

Allergy tests are recommended before exposing at-risk infants to peanut-containing foods between four months and 11 months of age.

These are youngsters who've had skin reactions to eating eggs or a severe eczema skin rash, which suggests a possible food allergy.

The recommendations are meant to serve as interim guidance while more extensive guidelines are prepared by the National Institute of Allergy, Asthma & Immunology and the European Academy of Allergy and Clinical Immunology. Those are expected by next year, the consensus statement said.
