FOOD ALLERGIES & FOOD SENSITIVITIES
When an aggravating food is consumed, a reaction occurs between the allergen and antibody that trigger the release of chemicals that lead to inflammation in body tissues. This can contribute to a variety of health problems:
Headaches and high blood pressure
Mood disorders (such as hyperactivity, depression, anxiety, inability to concentrate)
Asthma, chronic congestion and recurring respiratory infections
Eczema, psoriasis, acne and other skin conditions
Runny noses and puffiness around the eyes
Gastrointestinal symptoms (bloating, diarrhea, constipation, gas, IBS, Crohn’s disease, ulcerative colitis)
DO I HAVE TO AVOID IGG POSITIVE FOODS FOR THE REST OF MY LIFE?
The great thing about IgG food sensitivities is that, in many cases, with avoidance of a IgG positive food for a period of time, it can be re-introduced over certain intervals of time. This is because the allergen-antibody complexes have been gradually eliminated from the body with decreased exposure to the allergen. Your nutritionist can assist you with re-introduction of foods.
WHAT IS THE BENEFIT OF TESTING FOR IGG FOOD ALLERGIES?
IgG food allergies are extremely useful to test for and detect by way of food sensitivity testing because they are difficult to identify based on observation alone. Unlike IgE food allergies (the classic immediate and acute “food allergy” response, leading to hives, swelling or anaphylaxis), IgG food allergies present as a chronic delayed response, which may not be noticeable until several meals or even days have passed. These IgG food allergies present more like what most would consider as an “intolerance” or “sensitivity” response. Commonly, these present as chronic digestive (eg. irritable bowel syndrome) or skin conditions (eg. eczema, acne, psoriasis).
HOW MUCH DOES THE IGG FOOD SENSITIVITY TEST COST?
A expanded 200-food panel IgG sensitivity test costs $350. This includes the standard 96-food panel as well as foods found in various ethnic cuisines becoming popular in North America.
Turnaround time for test results is 2 weeks.
WHAT IS THE DIFFERENCE BETWEEN A FOOD ALLERGY, FOOD SENSITIVITY AND A FOOD INTOLERANCE?
The term allergy is basically an all-encompassing term that describes any ingested/inhaled/contacted substance that causes an undesirable response in the body. The above three terms (food allergy, food sensitivity and food intolerance) all refer to immune reactions to foods, but commonly are used to describe different pathologies behind these reactions.
A food allergy usually refers to IgE immune reactions to foods (think anaphylactic shock or other classic allergic symptoms).
A food sensitivity usually refers more to IgG immune reactions, which are slower to manifest and can be confused for other causes (i.e. low-grade inflammations, skin conditions like acne or eczema, etc).
A food intolerance refers to the body’s general inability to metabolize a food, which can lead to an immune response against that substance. For example, lactose intolerance and celiac disease are considered food intolerances because the body cannot breakdown or deal with lactose or gluten, respectively.
This method of testing was originally invented for studying DNA and gene expression. The same microarray technology has now been extended to Food Sensitivity testing. The Health Food Sensitivity test is a sensitive and accurate technique that can better detect the presence of IgG food-specific antibodies to over 200 commonly eaten foods in your diet.
As part of a quality program, samples are analyzed in duplicates. (Double checked)
Some common types of food intolerance are:
histamine, present in mushrooms, pickles, and cured food
additives such as artificial sweetners, coloring, or other flavorings
