What is food sensitivity?
Food Sensitivity are your body’s response (IgG antibody reactions) to certain foods that occur hours to days after certain foods are consumed. These are also termed as delayed food reactions.

Fish allergies cause immediate reactivity after consuming fish. Symptoms may include nausea, skin rash, stomach cramps etc.

Egg sensitivity causes a delayed reactivity, hours or days after consuming eggs. Symptoms may include belching, diarrhea, runny nose and skin reactions.

How is this different from food allergy?

Your immune system produces two types of antibodies commonly – Immunoglobulin E(IgE) and Immunoglobulin G(IgG) against certain foods.

Food allergies
Food Allergies are immediate reactions and can occur within minutes of consuming the reactive food. This involves IgE antibodies and may cause breathing, digestive disorders or skin rashes etc. On certain rare cases, it may be life threatening when it leads to anaphylaxis.
Symptoms to consider food sensitivity testing
  • Abdominal pain
  • Gas
  • Bloating
  • Nausea and vomiting
  • Skin itchiness and redness
  • Rashes like eczema
  • Bronchitis and asthma symptoms
  • Musculoskeletal joint pain
  • Muscle stiffness and swelling
  • Fever
  • Fatigue
  • Sweating and feeling weak

Undetected food sensitivities could lead to symptoms and systemic changes that are associated with certain conditions/illness.

Digestive disorders
Conditions like irritable bowel syndrome (IBS) and Crohn’s disease have been linked to IgG food reactions. Research has shown than elimination of IgG reactive foods can alleviate IBS symptoms.
Migraines
A 2007 research study found that 43/65 patients with migraine headaches had complete remission of headaches after one month of eliminating reactive foods. Another study in 2010 found a significant reduction in the number of headache days and migraine attacks with elimination of reactive foods.
Mood/attention deficit disorders
Deposition of antibody antigen complexes in nervous system tissues may contribute to hyperactivity, depression, anxiety, inability to concentrate and other mood disorders. There is some evidence that eliminating IgG food antigens improve attentiveness in children.
Weight gain
Antibody-antigen complexes in tissue cause inflammation, which leads to fluid retention and weight gain. To fight inflammation, the body releases a chemical called ghrelin, which also happens to be an appetite stimulant. Thus, IgG food reactions may contribute to weight gain in two ways: fluid retention and increased appetite.

Why test for food sensitivities?

Since food sensitivities are delayed reactions, testing is the only way to determine which foods are responsible for the reaction. IgG reactions frequently occur to commonly consumed foods such as dairy, wheat, eggs, yeast, pork and soy.

Elimination diets
(removing suspect foods for a period of time and then reintroduce and check for reactions) are difficult to follow and can take months to complete.

Rotation diets
Can be implemented working with our team of clinical dietitians.

Why vibrant

Vibrant is the only company that utilizes a chemiluminescent method of detecting food sensitivities on a silicon chip. While other labs use ELISA methods, our proprietary technology enables us to provide the highest sensitivity of detection. All 96 tests are performed in a single reaction vessel enabling the best accuracy and precision. We have a team of expert clinical dietitians who are trained on providing dietary recommendations based on your test results and having a personalized approach to work with your rotation plan and nutrition. Vibrant tests for IgG and IgA antibodies to food. IgA antibodies provides protection from mucosal damage. IgA reactivity to foods indicate mucosal damage. If IgG reactions are negative and you are still symptomatic, IgA reactivity helps provide solutions.

Intestinal permeability and food sensitivity

Your intestinal lining. in a healthy state will provide immunity against exposure to food antigens. Foods are not supposed cross the intestinal barrier to enter your blood stream. However, inflammation in the gut lining caused due to abnormal gut flora, stress, certain drugs and alcohol can cause the food particles to breach the barrier and enter the bloodstream where they cause an IgG antibody response. In a case where you see reactivity to multiple foods, an intestinal permeability may be the root cause. If so, your healthcare professional may choose to order the Intestinal Permeability Panel to confirm and suggest treatments to heal your intestinal lining in addition to dietary recommendations.

Rotation diet/elimination of foods

Once you receive your results, your healthcare professional can help you formulate a plan to rotate your diets/eliminate the problem foods from your diet. Most people see improvement of symptoms within a few weeks of eliminating the reactive foods or after going on a rotation plan. However,it is important to understand that symptom improvement make take some time, and results vary from individual to individual. Removing reactive foods from the diet can sometimes result in withdrawal symptoms like headaches, tiredness, irritability and hunger.

Frequently asked questions

How many foods are tested?
Vibrant tests for 96 most common foods that are consumed and includes Dairy, Meat, Seafood, Fruits, Vegetables, Grains, Legumes, Nuts and Nightshades amongst others.
How to order this test?
Please contact your doctor or nutritionist to get this test ordered now. If you don’t have one, we can help with finding doctors in our network who may be willing to order this test.
Do I have to avoid all the foods that show up as reactive?
Not necessary. You may be on a rotation diet where you could still eat some foods. Your personalized report and session with our dietitians can help better plan your nutrition. However, if your reactivities are considerably making you feel worse, it may be better to eliminate certain foods as necessary.
I have not eaten a particular food for many months, would it still show reactivity?
You are less likely to have antibodies to that food. In this case, a lack of reaction is most likely due to lack of exposure and does not necessarily mean the food is non-reactive.
Will this test show reactivity to foods I seldom eat or have never eaten?
Sometimes reactions appear for foods seldom or never eaten. For example: a child reacting to coffee. This may be due to cross-sensitivity with a related food, or may result from inadvertent exposure to that food (hidden ingredient in packaged food item or sauce). Elevated IgG may also have a role in protecting against more serious IgE reactions. It’s important to understand that having elevated IgG antibodies is not a concern if the reactive food is rarely eaten.
Where is the testing performed?
Vibrant Wellness Food Sensitivity is performed at Vibrant America Clinical Lab, a CLIA and CAP accredited laboratory located in San Carlos, CA.
