FOOD FOR THOUGHT Though the role of food allergies continues to be debated within the medical
community, we are still learning about the many ways that food allergies can
develop and impact children. In
the course of my 29 years as a pediatrician, however, I have
encountered a number of situations in which food allergies have been
directly related to childhood medical and behavioral problems.
The following two medical histories illustrate how the accurate
diagnosis and treatment of food allergies can provide relief
to otherwise baffling disorders.
Bill's Favorite Food Apples, Rice and Michael What Is A Food Allergy?
How Medical or Behavioral Problems May Be Related to the
Food Your Child Is Eating?
At the age of eight, Bill suffered severe daily migraine headaches, I
referred Bill to a pediatric neurologist,
who diagnosed psychosomatic migraines.
Based on the results of physical exams and EEG and other
neurologic tests, a medical cause for the headaches was ruled out.
This was in 1980, and I was beginning to hear from parents
about certain foods possibly causing recurrent infections and
difficult behavior in children. I asked Bill's parents if he had a favorite
food. They told me that he loved peanut butter and ate it every day. I
recommended that Bill's parents remove peanut butter from his diet for 14
days. We were all surprised and
delighted that Bill's headaches went away during the two-week
period. Bill's profound clinical response to the elimination of a craved
food piqued my interest in food allergies. I then began to
pursue further study toward the correlation between food allergies and
chronic medical problems in children.
In July, 1996, I examined a four-year-old boy with a history of
severe behavior problems, which included episodes of hitting
other children and throwing objects. Michael's medical history
included a problem with reflux, manifested by significant spitting and
chronic diarrhea between ages one and two. At the time,
removing milk and eggs from his diet helped the gastrointestinal
complaint. Aside from occasional ear infections, Michael was a
healthy child. Based on this history, I decided to allergy test the foods
in his diet. There was no indication that pollens and
molds should be treated as well. Michael was treated using
sublingual immunotherapy for 19 allergic foods. His most significant
reactions were to corn, peanuts, apples and
rice. Based on the allergy skin test reactions, Michael's mother
eliminated apples and rice from his diet completely. Only two months later,
Michael was doing much better in school. His
school reports between early summer and early fall depicted a dramatic
transformation. Teachers now described Michael to be
enthusiastic and attentive, with more productive work habits.
The issues that the medical community have with food allergies begin with
the definition of the term itself. To a physician trained in an American
medical school, food allergies are usually considered "fixed food
reactions." Foods such as shellfish, eggs
and peanuts can cause severe and adverse reactions--such as hives,
asthma and difficulty breathing--in an individual shortly after ingestion.
In my opinion, these reactions represent no more
than ten percent of all food allergy problems. Hidden food
allergies involve a food, or combination of foods, which when ingested
frequently cause symptoms such as headaches or aggressive
behavior. These food allergies are termed "hidden" because we do not
typically associate particular foods with an allergic reaction. In
addition, hidden food allergies can cause many other medical problems,
including: recurrent ear infections, and urinary frequency.
