New research suggests the method to stopping a lifelong peanut allergy is to, well, feed your baby peanuts.
The NIAID said peanut allergies are a growing health problem with no treatment or cure. It usually develops in childhood and remains into the adult years. In a 2010 survey, about 2% of U.S. children had a peanut allergy, which was more than four times the estimate in 1999.
The decision to rework the guidelines came after a trial of more than 600 infants found regular peanut consumption until age 5 reduced the likelihood of an allergy by 81%.
"The (Learning Early About Peanut Allergy) study clearly showed that introduction of peanut early in life significantly lowered the risk of developing peanut allergy by age 5," said Daniel Rotrosen, the director o NIAID's Division of Allergy, Immunology and Transplantation.
"As it turns out, counter-intuitively, that works against the child," he said.
Fauci said the new guidelines will "save lives and lower health care costs."
"We expect that widespread implementation of these guidelines by health care providers will prevent the development of peanut allergy in many susceptible children and ultimately reduce the prevalence of peanut allergy in the United States," he said.
The guidelines are based on whether a child has eczema or an egg allergy, good indicators of peanut allergies. Fauci suggests parents check with their doctor before moving forward with peanut foods.
The guidelines are as follows:
- For infants deemed a high risk for developing a peanut allergy, based on eczema or egg allergies, experts suggest feeding them food with peanuts as early as four to six months old.
- Infants with mild to moderate eczema should be introduced to peanuts at six months old.
- For babies without eczema or egg allergies, researchers say parents can start giving them peanut foods when they see fit.
