Almost 3 in every 100 Australian children have a peanut allergy and around 20% of children grow out of their peanut allergy.
Infants at high risk of developing peanut allergy, such as those with severe eczema and/or egg allergy (see Precautions).
Since delaying the introduction of peanut may be associated with an increased risk of developing peanut allergy, healthcare providers should recommend introducing peanut-containing products into the diet of infants at high risk early in life (between 4 and 11 months of age).
Compared with peanut avoidance, early introduction of peanut protein has been shown to lead to a significant reduction in peanut allergy in children up to the age of 5 years (70% relative reduction; NNT = 4).
Note : The Australasian Society of Clinical Immunology and Allergy (ASCIA) recommends introduction of solids, including peanuts, for all infants between 4 and 6 months (and not just those at high risk), with a new food every few days.
