The Food Allergen Labeling and Consumer Protection Act (FALCPA) requires U.S. It's important to read food labels to be able to stay away from foods that contain tree nuts. Tree nuts include almonds, pecans, walnuts, and cashews. The items that your child is allergic to are called allergens.Ī tree nut allergy is the immune system's abnormal response to the proteins found in tree nuts. This means your child can't have the food they are allergic to, or any products containing that food. When your child has a food allergy, he or she must follow an allergy-free diet. Even adding back one food can really mean a lot.Tree Nut Allergy Diet for Children General guidelines for tree nut allergy "I'm trying to seek the truth, and I'm trying to expand their diet as much as possible," Greenhawt said. And as with the more common peanut allergy, most children with a tree nut allergy don't outgrow it. children, according to Greenhawt and his coauthors. They're thought to affect an estimated 1% of U.S. "Everybody's got their comfort zone in which they may or may not challenge."

They might unnecessarily delay them for years until the patient has only a minimal antibody response on a skin prick or blood test, Greenhawt said. Still, he said, allergists tend to be reluctant to conduct food challenges for fear of potentially dangerous allergic reactions. When children pass an oral challenge, he encourages them to eat the nut several times a week, based on earlier research that suggests regular consumption helps prevent an allergy from ever developing. I've been sort of aggressively challenging kids for years." Nuts are nutritious, so "you want them to be able to enjoy that food," Greenhawt said. If he does a skin prick or blood test to check for co-sensitivities, he always wants to perform an oral challenge if the results are positive, "because I have no idea what this means.

“Oral food challenges are recommended in order to avoid unnecessary avoidance of pistachio nut in cashew nut-allergic patients,” the scientists concluded. And they all passed a mango oral challenge. But while all but one of the children tested positive on a skin prick or blood test for pistachio antibodies, two-thirds of them passed an oral challenge with the nut.

Cashews belong to the same family as pistachios and mangoes (who knew?), so children with cashew allergies are usually told to avoid eating the other nut or the fruit. In a related study, published online last week by the journal Translational Allergy, Dutch scientists recruited 29 children who were allergic to cashews. Every single child with a peanut allergy passed an almond oral challenge, suggesting that peanut allergy patients can safely eat that nut without first undergoing a skin prick or blood test or an oral challenge, the researchers concluded. Turns out that most of the children passed the oral food challenges, which means they weren't allergic to the nuts in question, even though their skin prick or blood tests were positive, Greenhawt and his coauthors reported in the Annals of Allergy, Asthma & Immunology. They then underwent a total of 156 “oral food challenges,” in which-under the supervision of an allergist who has medications available in case of an allergic reaction-they were given tiny but increasingly larger amounts of a tree nut for which they had tested positive but had never exhibited allergy symptoms. The children, all patients at the University of Michigan, where Greenhawt previously practiced, had undergone skin prick or blood testing for other nuts. Greenhawt and his coauthors examined the records of 109 children with a known tree nut allergy, 46 of whom also happened to have a peanut allergy. Interestingly, even some people with known pollen allergies test positive for nut antibodies, even though they're not allergic to nuts. If you're allergic to cashews, for example, you might test positive for pistachio antibodies, even though eating pistachios wouldn't cause you any problems. One reason is that some foods contain similar but not identical proteins. In other words, a positive skin prick or blood test “is not a surrogate for being allergic,” said Greenhawt, who chairs the American College of Allergy, Asthma and Immunology Food Allergy Committee and co-directs the Children’s Hospital Colorado Food Challenge Unit.
