Kids and Food Allergies: What You Need to Know

Food allergies in children are a big deal. Some kids grow out of them, but others don’t. So, what’s the deal? First, let’s talk about the good news. Milk and egg allergies are common, but many kids outgrow them. In fact, up to 95% of children eventually tolerate these foods. It often starts with baked goods like muffins or pancakes. Over time, some kids can even handle less processed forms. But here’s the catch: allergies like peanuts, tree nuts, sesame, and shellfish are tougher. Only a small number of kids outgrow these. Peanut allergies, in particular, are a big focus in research and management. So, why do some kids outgrow allergies while others don’t? It’s complicated. Experts point to a few factors. First, there’s IgE, an antibody that triggers allergic reactions. Kids with lower IgE levels are more likely to outgrow their allergies. High IgE levels mean a longer road to tolerance. Next, the severity and number of allergies matter. Kids with milder reactions or fewer allergies often outgrow them sooner. Multiple or severe allergies can stick around longer.Genetics also play a role. Food allergies are influenced by many genes and environmental factors. Some genes related to skin barrier function are linked to eczema and peanut allergies. But no genetic test can predict if a child will outgrow an allergy. Now, can parents do anything to help? There’s no magic home remedy, but there’s something called Oral Immunotherapy (OIT). OIT introduces small, controlled amounts of an allergenic food to build tolerance. It’s often used for peanut allergies and involves several office visits over months. Younger kids tend to do better with OIT. While OIT doesn’t guarantee permanent tolerance, it can raise a child’s reaction threshold and reduce worry about accidental exposures. Preventing food allergies is also important. Recent research shows that introducing allergenic foods early can reduce the risk of developing allergies. Pediatricians now advise introducing peanuts between four to six months of age, with similar findings for eggs. Another key factor is managing eczema. Eczema is linked to food allergy development. Inflamed skin can allow allergens to enter the body and trigger an immune response. Consistent skin care, like daily moisturizing, can reduce eczema severity and potentially lower the chances of developing a food allergy.
