Tree Nut Allergy Cure Status

Tree nuts include the following nuts that are grown from trees: almonds, beechnuts, brazil nuts, cashews, chestnuts, gingko, hazelnuts, hickory nuts, macadamia nuts, pecans, pine nuts, pistachios and walnuts. Peanuts are not a tree nut--they are part of the legume family as a peas.

“About 9 percent of children will outgrow tree nut allergies,” according to a study led by Robert A. Wood at Johns Hopkins University School of Medicine, “58% of children with tree nut specific IgE levels of less than 5 kilounits per liter passed an oral challenge. Based on these findings, researchers recommend that children with a current tree nut allergy be re-evaluated periodically by their allergist/immunologist to assess whether they have developed a tolerance and whether an oral challenge should be given. While an ideal cut-off has not been established, researchers suggest that oral challenges should be considered in children four years and older, and who have less than five kilounits per liter of tree-nut specific IgE in their blood…[But] children who are allergic to multiple types of tree nuts are unlikely to outgrow their allergy.”[1]

That begs the question, "What is there to do for the remaining ninety percent of children who do not naturally outgrow a tree nut allergy or have multiple types of tree nut allergies?"  It can be stressful for parents and children who have allergies to these nuts which may be found as ingredient in everything from health food bars, bouillon, Worcestershire sauce to non-food items like hackysacks, beanbags, draft dodgers or bird feed. Aside from avoiding tree nuts, there is more hope for a cure. In 2010 FAAN awarded Dr. Staciei Jones of Arkansas Children’s Hospital to receive grant money for the purpose of developing, “tree nut-specific immunotherapy for people who have multiple tree nut allergies. Considerable progress has been made using oral immunotherapy approaches for other food allergens, but this will be the first study to focus on the treatment of multiple tree nut allergies.”

For more details on tree nut allergens, probiotics and stories from mothers who have successfully handled tree nut allergies in their children, see chapters 9-22, 38, 40,42 in Flourishing with Food Allergies.

Thank you for helping inform allergy sufferers about alternatives to avoidance and shots to treat tree nut allergies. I have also had success using NAET to reduce IgE RAST scores which is the accepted measure of allergic reactions. To find out a little more go to allergyfocus.net/tree-nut-allergies/

There are lot of treatments like avoiding foods containing the allergen, adrenaline injection if anaphylactic reaction occurs, antihistamines, bronchodilators for asthmatic symptoms.It also includes dietary modification and allergen avoidance - with education of children, parents and carers
