What is a Food Allergy?

 
By definition, "A food allergy is either an immediate or delayed reaction resulting in an inflammation or irritation of the human body's tissues, organs, and/or systems caused by a foreign sensitizing substance known as an antigen, which is one of the body’s defense mechanisms."
 
 
When it comes to food allergy there are four types...
 
 
Type 1: Reactions typically occur in less than 2 hours, though there are reported incidents of longer response times, which are characterized by IgE binding with a specific antigen resulting in leukocyte release of tissue irritant chemicals including leukotrienes, lysosomal enzymes, histamines, kinin- and bradykinin-like substances and dehydroascorbic acid, resulting in inflammation and irritation.
 
Type 2: Cytotoxic reactions involving IgM and IgG immunoglobulins resulting in cell destruction.
 
Type 3: Delayed reactions involving immune complex mediated reactions that can result in tissue injury if deposited in tissues. This type of hypersensitivity has been shown to involve IgG immunoglobulins.
 
Type 4: Delayed reaction not involving immunoglobulins. Primarily involves T-lymphocytes, resulting in inflammation 36 to 72 hours after contact.
 
 
Of these, Types 1, 2 and 3 are the focus of this page...
 
 
* Type 1 Immediate Food Allergy (Classic-Onset, IgE-Mediated):
 
This allergic reaction to foods involves the Immunoglobulin E (IgE) antibody and also involves MAST cells. It is the most understood, but least occurring immune response to foods. It occurs in less than 2-3% of adults and less than 5% of children. On an average, the reaction time usually occurs anywhere from seconds to up to 2 hours; though in some cases, longer reaction times have been reported.  Typically, an IgE-mediated food allergy affects the skin, airways or the digestive system. The most commonly known response is anaphylaxis, which can result in death. This type of food allergy is typically tested in a doctor's office by means of a skin "scratch" test or a by means of a laboratory blood test known as an IgE RAST and/or IgE MAST.  Additionally, it only takes a single food to cause a reaction and it is typically a food that is rarely eaten.
 
 
* Type 2 & 3 Delayed Food Allergy (Food Intolerance, IgG-Mediated):
 
This allergic reaction to foods involves the Immunoglobulin G (IgG) antibody and DOES NOT involve MAST cells. It is the lesser understood, but most common immune response to foods. It occurs in anywhere from 45-60% of the general population and affects children and adults equally.*  The reaction time occurs anywhere from a couple of hours and up to 2-3 days after consumption of the food.
 
Any system, tissue, and/or organ in the body can be affected; and there are over 118 medical conditions/symptoms, which have been shown in the published medical literature as either being caused and/or provoked by this type of allergic response to foods. 
 
Types 2 & 3 induced conditions include, but are not limited:
 
~ Acne
~ ADD/ADHD
~ Allergic Shiners (Dark Circles under Eyes)
~ Arthritis
~ Asthma
~ Autism
~ Candidiasis
~ Celiac Disease
~ Chronic Fatigue
~ Dermatitis Herpetiformis
~ Diabetes
~ Digestive Disorders
~ Ear Infections
~ Eczema
~ Edema
~ Fibromyalgia
~ Headache
~ High Blood Pressure & Hypertension

~ Snoring
~ Tiredness
~ Weight Challenges & Weight Gain
~ Plus over 90 more Nagging & Chronic Ill-Health Conditions*
 
* Note: The published medical research has linked IgG-mediated food allergy and food intolerance to over 118 chronic & "nagging" ill-health conditions.  CLICK HERE to review a sampling of the peer-reviewed, clinical research, which has been published over the course of the past many decades in the world's most recognized medical journals.
  
Conventional skin "scratch" testing and IgE RAST/IgE MAST blood tests are incapable of detecting this type of food allergy.  Even more intriguing is how both a single food and combination of foods can cause this type of reaction - and it is usually with foods regularly eaten.
 
The reliable way to properly screen Type 2 and 3 Delayed-Onset IgG-Mediated Food Allergy (Food Intolerance) is with the validated and accurate finger-stick, at-home 96-Food IgG ELISA Food Intolerance Screening Kit.
