Tips to potentially prevent peanut allergies from Gottlieb allergist
MELROSE PARK, Ill. – (March 25, 2015) - Peanut butter and jelly sandwiches are a dietary staple for many children. But for others, peanut products can be life-threatening and are strictly taboo. A new study released at a meeting of the American Academy and Association of Allergies and Immunology (AAAAI) and published in the New England Journal of Medicine suggests that peanut allergies can be prevented through early exposure.
“The importance of this study will really change the way peanuts are introduced in children’s diets,” says Rachna Shah, MD, board-certified allergist at Gottlieb Memorial Hospital, part of Loyola University Health System. Often, peanut introduction is recommended when the child is between 2 and 3 years of age. Pregnant or lactating women may be told not to consume peanuts to prevent allergies.
More than 1.3 percent of children in America are allergic to peanuts. “Symptoms of peanut allergies are hives, vomiting, rash, shortness of breath, decline in blood pressure and even death,” says Dr. Shah, affiliate faculty member at Loyola University Chicago Stritch School of Medicine. “If a child eats or even is exposed to peanuts, a reaction could range from something as relatively simple to treat as hives to a life-threatening episode.”
Treatment for peanut allergies in children currently is limited to avoiding peanuts. Peanut allergies generally cannot be outgrown. If a child is allergic to peanuts, it is likely they will also be allergic to other tree nuts like almonds, cashews, hazelnuts, pecans, walnuts and pistachios.
Delayed exposure to peanuts did not decrease the development of peanut allergies. In fact, early introduction and regular consumption of peanuts led to a reduced likelihood of developing a peanut allergy after the age of 60 months.
“Bottom line, early introduction of peanuts decreases the frequency of developing a peanut allergy,” says Dr. Shah, who treats many children as well as adults with peanut allergies in her Gottlieb Memorial Hospital practice. “The estimated prevalence of peanut allergy in America is 1.4 to 3 percent and the numbers are growing so this news offers a potential real solution to prevention.”
Dr. Shah recommends these tips for introducing peanuts to a child’s diet:
Introduce peanuts in a controlled setting like your home. “The last thing you want, is for the introduction to happen in a restaurant or party where you might not be able to directly monitor the symptoms of a reaction.”
Introduce a very small amount of peanuts or just a taste. “Wait 30 minutes after offering a taste of peanuts and then give a larger amount. Repeat this after a few days. Sometimes the reaction can occur with second exposure to the peanut.”
Introduce with an age-appropriate peanut source. “Smooth peanut butter or the Israeli snack Bombas that are teething snacks made of peanut powder are great small steps for peanut exposure.”
Assess the likelihood of genetic allergies. “If there is a parent or sibling that has a peanut allergy, the family should seek the advice of an allergist who knows how to introduce peanuts.”
Allergists in Dr. Shah’s office at Gottlieb Memorial Hospital have the sole distinction of conducting the official allergy count for the Midwest during allergy reporting season. Gottlieb allergists are uniquely certified by The American Academy of Allergy, Asthma and Immunology to perform the Gottlieb Allergy Count.
