FOOD ALLERGIES
LINKED TO AUTISM?
Sidney MacDonald Baker, MD
(EDITOR'S NOTE: Autism is growing at near
epidemic rates in certain regions of America
and parents of autistic children are caught
in a double bind,
...as their children's discomfort increases,
recommended treatments show promise at
first, but eventually disappoint, and the
range of options offering hope, seems to
dwindle.
Anyone who has suffered with the wide
spectrum of symptoms associated with autism
understands how frustrating it can be...
...with all the remarkable advances in
modern medicine, they must continue to
struggle.
...The good news is that
some fellow sufferers have found a path to
relief, and while not a solution for every
situation, the path that they followed is
contained within this article.)
Are you unknowingly feeding your
child foods that cause or aggravate autistic
symptoms?
Read what one medical doctor has found
over 30 years in practice...
Children with autism are sensitive. Of the
thousands of children I have known in thirty
years as a doctor, the few hundred with
problems in the spectrum related to autism
stand out as the most distinctively
sensitive of them all. Touching, tasting,
hearing, smelling, and seeing involve an
enterprise that is not only characterized by
difficulties in processing and organization
but is also involves a heightened, often
painful, sensitivity.
What does it mean to be sensitive?
We all know what it feels like to have
sunburned skin or a reaction to a certain
sound of chalk on the black board and we can
empathize with children who are involved in
a more global sensitivity, but we scientists
still do not understand what happens at the
cellular or molecular level to change a
persons reactivity from normal to
sensitive. Even the words we use:
hypersensitive, allergic, intolerant,
hyper-reactive do not have precise
definitions. Many physicians, however, would
quibble if we were to say that autistic
children are allergic as opposed to
allergic children are sensitive.
How Doctor Baker discovered the
behavioral allergy connection...
I
was such a physician. Twenty five years ago
when a child psychiatrist sent me Martin
Zelson for evaluation of his seasonal
behavioral deterioration. Martin was on the
verge of being thrown out of his school
program where he was in a group of other
school aged children with severe
developmental and behavioral problems,
mostly in the autistic spectrum. Martin was
aggressive, hyperactive, and destructive.
...I was skeptical, proficient in allergy
evaluation, and was a former school boy New
England wrestling champ. Evaluation and
treatment of Martins inhalant and food
sensitivities resulted in a major
improvement so that he was able to benefit
more from his school program and participate
in family activities that would have
previously been impossible. His allergic
responses were cognitive and behavioral in
the absence of the kinds of symptoms we
usually consider to be allergic (stuffiness,
eczema, wheezing, itching).
3 decades in practice revealed how
common allergies are with children...
As it turns out, I have learned in the past
three decades that Martin was not an
exception. Most children with his kinds of
problems - and including children with all
sorts of attention problems - have
hypersensitivity to foods, and inhalants.
Those of us physicians who have taken a
close look not just at their histories and
allergy test results but at their
biochemistry and immune systems now
recognized that they tend to be in a state
of inappropriate immune activation.

Autism is not caused by allergy, and
yet...
Dont get me wrong. I am not saying that
autism is caused by allergy. I am saying
that children who have problems in the
autistic spectrum (as well as children who
have significant attention problems) are
sensitive not just in the area of their
senses, but also in their immune systems
reaction to the environment. This
association is a lot easier for me to
understand if I look at the central nervous
system (CNS) and immune systems from a
functional, as opposed to an anatomical,
point of view.
Anatomically the CNS and immune systems are
quite distinct and different. One is made up
of stationary long branching permanent cells
with a compact headquarters between ones
ears. The other is made up of a disseminated
population of short-lived mobile cells with
no specific organ to call home. Pick up any
textbook of anatomy, physiology, or
pathology. The CNS and immune system
chapters are widely separated as are the
experts who wrote the chapters. From the way
I see it, however, they are a functional
unit.
An important hidden link between the
CNS and immune system...
Look at it this way: The cells of both
systems arise from the same origin in the
neural crest of the embryo. Both systems
contain the only cells of our bodies that
exist as permanent, undividing cells from
infancy to old age. (Such long-lived cells
are a subset of the otherwise ephemeral
cells, lymphocytes, of the immune system.)
Both systems have the job of perceiving the
environment. The CNS takes in the big world
of our senses, our every day cognitive
experience. The immune system takes in the
microscopic or molecular world of that has
to do with sensing the constant presence
of friendly or unfriendly (such as cancer)
cells, germs, food molecules, and toxins.
The chemistry of the immune system
perceiving its tiny environment is not very
different from our nose smelling the bread
baking in the oven. However we have a direct
experience of the bread while our immune
system only makes us aware of its activities
when something seems to be quite wrong, and
the message that something is wrong may be
quite delayed or obscure. The memory of your
fifth birthday party when your friend
Jeffrey spilled purple juice all over your
new sneakers is in your CNS. That same week,
when the doctor gave you your shot against
tetanus, diphtheria, and whooping cough, the
enduring memory of the taste of those
germs was evoked in your immune system where
it remains today. The birthday and the
immunization are stored differently in you
body, but functionally they are come under
the same heading: perception and memory.
Another important link between the
CNS and immune system...
Perception and memory are the basis for
recognition. Recognition is a term we use
interchangeably to describe the day to day
activities of both our CNS and our immune
systems. Finally, both of these two systems
share the capacity for this mysterious
process called sensitization, which is, in a
way, an inconvenient or painful alteration
of the memory and recognition process.
Viewed from this perspective, it is not
surprising that children who have problems
with taking in and processing the world
express that problem on both the cognitive
and immune levels. They are really just
different aspects of the same underlying
mysterious disorder.
We try to help our children organize and
integrate their cognitive world by imposing
certain simplified order. Such order may
take the form of repetitive behavioral and
linguistic exercises or efforts to modify
responses (desensitize) to sensory input. On
the immune level we try to impose a
simplified order by avoidance of, or
desensitization to, offending foods and
inhalants. This applies whether the
mechanism of the reaction to foods, for
example, is allergic within the academic
definition of the word or intolerant
within a notion that covers a variety of
mechanisms, including the mischief caused by
certain peptides derived from gluten and
casein.
Helping a picky, hypersensitive
child...
So you have a picky kid. Your job is to help
him or her learn better picking. If her or
she chooses to limit his or her activities
to monotonous behavior, you try to broaden
his or her cognitive experience by picking
and presenting other, more useful, kinds of
stimuli. If he or she is sensitive to
tastes, touch, smells, sights or sounds, you
take steps to help him or her integrate and
become less painfully sensitive to these
stimuli. If your kids immune system is
picky, your job is to find the stimuli that
are bothersome, and present ones that are
not mischievous.
How important is the food allergy
link to children?
...When you have lots of other things to
think about, should you change the diet of a
child who has decided to live on French
fries, smooshed bagels, chocolate milk,
pretzels, Twinkies and diet coke, rejecting
all alternatives with an iron will? Yup! And
when you get over the hump, you are likely
to be rewarded with changes in sleep,
behavior, attention and sensitivity that
make the struggle worth it. There are
several ways of checking for food allergy.
Trial and error changes in diet are tedious
but inexpensive. I have found IgG ELISA
blood testing as done at Immuno Laboratories
to be a reliable measure both in term of my
experience with individuals as well as in
research studies done to validate the test.
Dr. Baker practices, writes, and does
research in Connecticut. He is a graduate of
Yale School of Medicine and former Director
of the Gesell Institute of Human Development
in New Haven.
