Hello my name is Carina Venter.
I'm an Allergy
Specialist Dietitian and
today we will be discussing
the Role of Nutrition
in the Management
of Peanut Allergy.
0:12
For the overview of the
slides and the presentation,
we will focus on nomenclature
and really how we define
different kinds of
food allergies and
then we will talk
about the dietary management of
food allergy with an
emphasis on peanut allergy,
talking about the
elimination phase,
the diagnostic phase, and
then the management phase.
0:35
The National Institute of Allergy
and Infectious Diseases, or NIAID,
defines a food allergy as
an adverse health
effect arising from
a specific immune
response that occurs
reproducibly on exposure
to a given food.
What that basically
means is that
we cannot be allergic
to peanuts one day,
the next day be able to eat some
peanuts or half a bar of Snickers
and then the day
afterwards again being
peanut allergic.
So, it means that we're allergic
to the food and
every time we eat
the food we will get a
reproducible reaction.
Although the reaction may not
be exactly the same every time,
sometimes it may be hives,
another time it could be rashes,
another time it may
be acute vomiting
followed by abdominal
pain and few hives.
It's important that we understand
the differences between
IgE and non-IgE-mediated
food allergies.
1:31
On this slide and the next
few slides I will explain
the differences between IgE
and non-IgE-mediated
food allergies.
Food allergies in the
umbrella term can be
divided into IgE-mediated
food allergies.
These really are the
food allergies where we
get symptoms within two hours of
consuming the food but
most often it would
really happen within a few
minutes, even a few seconds.
The bigger umbrella of food
allergies are referred to
as the non-IgE-mediated
food allergies.
These are divided into food
protein-induced enterocolitis,
other forms of known IgE
mediated food allergies
which we most often see in
the gastrointestinal clinics,
not so much in allergy clinics
such as enteropathies.
We also get use in
eosinophilic esophagitis
and mild to moderate non-IgE mediated
food allergies primarily and
triggered by cow's milk
consumption in young infants.
And so where does the peanut
allergy fall into all of this?
The peanut allergy
is predominantly
associated with IgE
mediated food allergies.
We may eat peanut
butter or we may have
a smoothie with peanut
flour in it and within
two hours we have some types of
hives or streaming eyes like
we would call rhinorrhea.
It's very rarely seen in food
protein-induced enterocolitis,
although it has been reported.
It has also been reported in
using eosinophilic
esophagitis but it is not
one of the major triggers
of these types of
food allergies.
