Reversal On Peanut Allergy
Peanuts are back on the menu. In a significant reversal from past advice, new national health guidelines call for parents to give their children foods containing peanuts early and often, starting when they’re infants, as a way to help avoid life-threatening peanut allergies.
The new guidelines, issued by the National Institute of Allergy and Infectious Diseases on Thursday, recommend giving babies puréed food or finger food containing peanut powder or extract before they are 6 months old, and even earlier if a child is prone to allergies and doctors say it is safe to do so. One should never give a baby whole peanuts or peanut bits, experts say, because they can be a choking hazard.
If broadly implemented, the new guidelines have the potential to dramatically lower the number of children who develop one of the most common and lethal food allergies, said Dr. Anthony Fauci, the institute’s director, who called the new approach “game changing.”
Could the new guidelines mark the end of the peanut-butter-and-jelly sandwich bans so common in school lunchrooms? “If we can put this into practice over a period of several years, I would be surprised if we would not see a dramatic decrease in the incidence of peanut allergies,” Dr. Fauci said.
Peanut allergies are responsible for more deaths from anaphylaxis, or constriction of the airways, than any other food allergy. Though deaths are extremely rare, children who develop a peanut allergy generally do not outgrow it and must be vigilant to avoid peanuts for the rest of their lives.
Dr. Lack and fellow scientists tested the hypothesis in a large clinical trial in England. They recruited hundreds of infants aged 4 to 11 months, all of whom were deemed at high risk of developing a peanut allergy because they had eczema or an allergy to eggs. After running skin-prick tests on the babies and excluding those who were already allergic to peanuts, they randomly assigned some babies to be regularly fed peanut products, and others to be denied all peanut-containing foods.
By the time they turned 5, only 1.9 percent of 530 allergy-prone children who had been fed peanuts had developed an allergy, compared with 13.7 percent of the children who were denied peanuts. Among another group of 98 babies who were more sensitive to peanuts at the start of the study, 10 percent of those who were given peanuts developed an allergy, compared with 35 percent of those denied peanuts. The findings, published in The New England Journal of Medicine in 2015, “shook the foundation of the food allergy world,” Dr. Greenhawt said.
The new guidelines divide children by risk. Low-risk infants, who don’t have eczema or an egg allergy and who have started solid foods, can be introduced to peanut-containing foods around 6 months at home by their parents. So can moderate risk children, who have mild eczema.
High-risk infants, who have severe eczema or an egg allergy, should be introduced to peanut-containing foods as early as 4 to 6 months, after they start other solid foods and are evaluated by a doctor for safety.
If your baby is determined to be high-risk, the guidelines recommend an evaluation by an allergy specialist, who may order allergy testing and introduce a peanut food in the doctor’s office, Dr. Greenhawt said. Even if allergy tests show sensitivity to peanuts, the baby isn’t necessarily allergic and may benefit from eating peanut foods, he said. A baby with a stronger reaction to the skin test may already be allergic, however, and the doctor may decide to recommend complete avoidance.
One way to introduce your baby to peanuts safely is to mix a couple of teaspoons of smooth peanut butter with a couple of teaspoons of warm water and stir until it has a smooth soupy or purée-like consistency, suggested Dr. J. Andrew Bird, pediatric allergist with UT Southwestern Medical Center and Children’s Medical Center in Dallas, who wrote a paper on the subject.
Foods containing peanuts should not be the first solid a baby eats, Dr. Greenhawt said. It’s also important to continue feeding the peanut-containing food regularly, aiming for three times a week, through childhood.
He acknowledged the new recommendations may face resistance. “The nuts and bolts of getting everyone to buy in to this and trust the recommendation and the data is a big unknown,” Dr. Greenhawt said. But the potential, he says, is enormous.
“This won’t outright prevent every single case of peanut allergy – there will still be some cases – but the number could be significantly reduced by tens of thousands,” Dr. Greenhawt said. “In the best case scenario, every allergist across the U.S. could be seeing fewer cases of peanut allergy — and that’s a good problem to have.”
