There are four different types of immune reactions in food allergy.
These are called Types 1, 2, 3, and 4. More than one type of
reaction can occur at the same time in the same allergic
individual. Types 1 and 3 are the focus of this page.
Type 1 (Immediate-Onset) Food Allergy
known and well-studied form of food allergies is called a Type 1 immune
(aka - a classical food allergy, immediate-onset, IgE-mediated, atopic
allergies, etc.). Type 1 food allergies occur in approximately
2-5% of the population. Type 1 food allergies occur mostly in
children and are less frequent in adults. Usually occurring in
the genetically predisposed individual, the immune system begins
creating a specific type of antibody called Immunoglobulin E (IgE) to
certain foods. One side of the IgE antibody will recognize and
bind to the allergic food. The other side of the antibody is
attached to a specialized immune cell packed with histamine, called a
Mast cell. Primed for action, the IgE antibody now only have to
patiently wait for re-exposure to food allergens.
When you eat the allergic food the next time, IgE antibodies hungrily
latch onto the food. Instantaneously histamine and other
allergy-related chemicals (chemical mediators) are released from the
mast cell, quickly bringing on the unwelcome appearance of
stomach cramping, diarrhea, skin rashes, hives, swelling, wheezing or
the most dreaded of all Type 1 reactions, anaphylaxis.
Type 3 (Delayed-Onset) Food Allergy
Type 3 immune reactions are much more commonly involved in food allergy
than Type 1 reactions. In fact, 45-60% of the population has been
reported as having Type 3 food allergies. (Note: According to
world authority James Braly, M.D., "70%-80% of Americans currently
suffering from chronic medical conditions of unknown cause, who have
proven poorly responsive to conventional medical interventions, are
suffering from IgG-mediated delayed-onset food allergies.") A
Type 3 food allergy (aka - delayed food allergy, food sensitivity, food
intolerance, etc.) also involves the immune system. They occur
when your immune system creates an overabundance of antibody
Immunoglobulin G (IgG) to a specific food. The IgG antibodies,
of attaching to Mast cells, like IgE antibodies in Type 1 allergies,
directly to the food as it enters the bloodstream, forming different
of so-called circulating immune complexes (food allergens bound to
circulating in the bloodstream). The allergic symptoms in Type 3
reactions are delayed in onset - appearing anywhere from a couple of
to several days after consuming allergic foods. Delayed food
may occur in any organ or tissue in the body and have been linked to
causing and/or provoking over 100 allergic symptoms and well over 150
medical diseases. An estimated 60 to 80 million Americans suffer
clinically significant food allergies and most all of whom suffer
The Difference Between An Immediate & A Delayed
1). Once thought to
only "real" food allergy, immediate food allergy is common in children,
rare in adults. Once thought to be uncommon at best, delayed food
is now considered the most common form of food allergy in children and
2). Allergic symptoms
in immediate reactions occur within two hours of eating. Allergic
symptoms in delayed reactions do not appear anywhere from at least 2
hours to 2 days (there are even reports of delayed symptoms appearing 3
to 7 days after
3). As a rule,
immediate-onset food allergy involves one or two foods in the
diet. Delayed reactions characteristically involve 3 to 10 foods,
sometimes as many of 20 foods in very allergic individuals.
4). Because a small
amount of a single food is involved and the allergic symptoms appear
immediately, immediate food allergy is usually self-diagnosed.
Example: You eat the food, it causes symptoms quickly, you are able to
see the connection and you stop eating the food. Due to a
combination of delayed symptoms, multiple foods, and food cravings,
Type 3 delayed-onset food allergies are extremely hard, if not
impossible, to self-diagnose. The only accurate and reliable way
to detect the delayed allergic foods is by means of laboratory
5). Immediate food
allergy involves foods that are rarely eaten. Delayed food
allergy involves commonly eaten foods (i.e. - foods that you eat every
day and may even have a craving for).
6). When people quit
eating foods that cause immediate symptoms, they have no withdrawal or
detoxification symptoms. Powerful addictive cravings and
symptoms are reported in over 30 percent of delayed food allergy
when they stop eating food.
7). Immediate food
allergens primarily affect the skin, airway and the digestive tract.
Virtually any tissue, organ or system of the body can be affected by
delayed food allergy. This includes the brain, joints, muscles,
hormone-producing glands, lungs, kidneys, and nervous
system. Additionally, delayed-onset food allergy is linked
to over 100 medical conditions involving every single part of the body
and some 100 different allergic symptoms.
food allergies are frequently permanent and fixed allergies.
Example: Once you develop an allergy to peanuts or shellfish, it's for
life. Delayed-onset food allergies are commonly reversible.
If you completely eliminate the allergic foods for 3 to 6 months, you
can reintroduce most of them (approx. 86%) back into your diet and
remain symptom-free. Because delayed-onset food allergies are so
often undetected and untreated, they lie behind many chronic medical
conditions of unknown cause. The
allergic person suffers for years, even decades, without ever
suspecting that their health problems are being caused by what they
food allergy is a skin ("scratch") test positive allergy. Delayed
food allergies are skin ("scratch") test negative. The
traditional skin tests are poor tests for detecting delayed food
allergies. Instead, delayed reactions food require
state-of-the-art blood tests. These tests detect serum
levels of IgG antibodies to foods.
10). Because delayed
food allergies do not make themselves apparent immediately and can be
caused by multiple foods, they are very difficult to detect without
specialized laboratory testing. There are many forms of allergy
testing available such as cytotoxic, computerized cytotoxic, applied
kinesiology, vega tests, and others, but each of these tests share the
same critical disadvantage - they are frequently unreliable.
known laboratory test for accurately identifying delayed-mediated
allergic foods is the IgG ELISA Delayed Food Allergy Assay. But
While various laboratories provide this type
Optimum Health Resource Laboratories can guarantee ALL
1). Research and Validation -
research supporting IgG ELISA Food Intolerance Testing is
substantial. There are MANY
studies, including independent double-blind, placebo-controlled trials,
screening of IgG-mediated food allergy.
2). Patient Satisfaction -
can claim their IgG ELISA food allergy test is a good one, but the real
to fame" comes from the patients who have had the laboratory's
of our patient study reports the following regarding the screening
services provided by
Optimum Health Resource Laboratories (YNL):
* A distinct and clear majority of patients taking the test and
altering their diet report that they found significant improvements in
Strong improvements were noted in 84% of all cases.
Often these improvements were noted as being life changing.
The degree of benefit was found to be particularly strong when patients
reported they rigorously altered their diets, though benefit was still
noted when diet was only moderately altered.
An overwhelming majority reported the process to be easy to administer
Over 90% said they would recommend OHR's testing to others.
3). Ability To "Reproduce" a Split Sample -
If you were to have your blood drawn, divided into two test tubes
("splitting the sample") and send both tubes of your blood to the same
unsuspecting lab under two completely different names, the two lab
results should be nearly identical (i.e., in terms of proper
identification of reactive foods and the degree of reactivity, the two
test results should agree with one another at least 90-93% of the time).
This process is known as "reproducing a split sample" and amazingly
enough, most IgG ELISA Food Allergy testing laboratories are unable to
do this! Not so with Optimum Health Resource Laboratories' IgG
Food Intolerance Test! In fact, we challenge anyone to send in
4). Specimen Stability -
and reproducibility, it is important for a delayed food allergy test
to be influenced by the stability of a specimen. Specimens which
within 24 hours of the blood draw cannot be considered reliable.
only are the results affected, but the patient is considerably
due to the need for a re-draw. Some laboratory's require that
are received within 24 hours of the blood draw while others allow
5-10 days. Optimum Health Resource Laboratories' testing allows
to be received up to over 4 weeks from the date of specimen collection!
5). Testing of All IgG Sub-Classes -
There are four sub-classes of Immunoglobulin G (IgG). These are
IgG-1, IgG-2, IgG-3 and IgG-4. Clinical research has identified
that significant allergens are mediated by all four. By not
screening for all sub-classes, treatment may be only partially
effective. Optimum Health Resource Laboratories tests for all 4
subclasses with its IgG ELISA Food Intolerance Test.
6). Convenience and Cost -
reality of life is that we are all busy and have many "things" to
do. Additionally, these "things" cost us time and, almost always,
money. With the
exception of our allergy screening services, all IgG ELISA food allergy
testing being provided in the United States by other laboratories
that the person needing and/or wanting to be screened for IgG-mediated
food allergy testing must have an ordering physician prescribe the test
and that a medical profession, such as a phlebotomist, doctor, nurse,
etc., perform a blood draw. Both of these have their own
costs... both in time and money. Optimum Health Resource
Food Intolerance Test DOES NOT require either of these! *
Additionally, while other laboratories demand anywhere from over
$500.00 to more than $1000.00 for their food intolerance testing,
Optimum Health Resource Laboratories' 96-food assay has a cost of only
plus we provide a Money Back Guarantee!
Note: We will provide one of our M.D. staff physicians to be your
ordering doctor at no additional cost or feel free to
ask your own physician to contact our office and set up an account so
he or she may order the
IgG ELISA Food Intolerance Test for you.
