Show 1229: The End of Food Allergies

Very likely you have heard of children who are allergic to peanuts. Sometimes the tiniest whiff of peanut dust can trigger a frightening reaction. Food allergies have been increasing dramatically among American children. In fact, one in 13 is vulnerable to a serious or life-threatening consequence if they accidentally consume the wrong food.

Avoiding Food Allergens:

The standard advice for families in which someone has food allergies is to keep those foods out of the house and away from the allergic individual. Parents may need to worry about cross-contamination, and events like school picnics or birthday parties can be scary. Pediatricians used to warn parents whose young child might have an inherited tendency to allergy that they should not let the baby have any exposure to possible allergens. That is now beginning to change, with studies demonstrating that early exposure to peanut protein, for example, may be protective.

Still, once a youngster has had an allergic reaction, vigilance is key. The allergic individual or the parent must keep epinephrine (EpiPen) on hand at all times in case of anaphylaxis.

Is There Another Way to Deal with Food Allergies?

Research on oral immunotherapy is encouraging. This approach is not yet standard in most pediatricians’ offices, so you may have to hunt for a clinical trial. However, as our guests explain, a person could be exposed to a controlled tiny amount of the food allergen to desensitize the immune reaction. Subsequently, the doctor gradually increases the quantities under safe, controlled circumstances. The goal of this treatment is that the immune system adapts. Sloan Barnett’s two children went through this protocol under the guidance of pediatrician Kari Nadeau. They tell us how it is done, and how the outcome could save lives. We stress, however, that this is NOT a project that you can or should try at home. Medical supervision is crucial.
