Food Sensitivity Testing

Only a specific group of individuals are ideal candidates for food sensitivity testing. The majority of people often have an unhealthy gut characterized by the presence of harmful bacteria and inflammation. Distinguishing between those who may benefit from testing and those who may not can save you both time and money. Leave it up to a trained professional to determine the right path for you!

Which Test is right for you?

Food sensitivity testing aims to identify foods that may trigger adverse reactions in individuals. Unlike food allergies, which involve the immune system and can be severe, food sensitivities typically involve milder reactions and may be related to factors like enzyme deficiencies, sensitivity to food components, or a poor microbiome.

There are various methods for food sensitivity testing, including blood tests that measure IgG (Immunoglobulin G) antibodies to specific foods, elimination diets, and at-home test kits. However, the accuracy and reliability of these tests can vary, and some healthcare professionals question their validity.

The results of food sensitivity testing are used to guide dietary modifications, such as eliminating or reducing consumption of identified trigger foods. This approach is often used in functional medicine and holistic health practices to address chronic health issues, digestive problems, and inflammation.

It’s important to note that while food sensitivity testing can provide valuable insights, it should be interpreted in conjunction with a thorough medical evaluation. Working with us can help ensure that lab testing, dietary and supplement choices are appropriate and beneficial for overall health.

Eliminate the Guesswork from Your Symptoms with Precision Food Sensitivity Testing

Identifying the root cause is crucial!

Food allergies involve an immune system reaction and can be severe, while food sensitivities are typically less severe and involve a delayed response. Allergy symptoms are immediate, whereas sensitivity symptoms may take hours to days to appear.

Food sensitivities and gut issues like dysbiosis can share symptoms such as bloating and digestive discomfort. However, dysbiosis is related to an imbalance in gut bacteria, while food sensitivity involves a specific reaction to certain foods.

Symptoms can vary but may include digestive issues, headaches, fatigue, joint pain, and skin problems. Identifying and eliminating trigger foods can help alleviate these symptoms.

Food sensitivity testing typically involves blood tests that measure IgG antibodies. These antibodies are associated with delayed immune responses and can help identify specific foods causing sensitivity.

Identifying and eliminating foods causing inflammation may contribute to weight management by reducing inflammation and improving overall well-being.

Gut health is crucial for overall wellness. Imbalances, such as dysbiosis, can lead to various health issues. Food sensitivity testing can help pinpoint dietary factors contributing to gut-related symptoms.

Results vary, but many individuals experience improvement within a few weeks of eliminating trigger foods. Full resolution of symptoms may take longer.

Yes, food sensitivity testing is suitable for children. It can be beneficial in identifying and managing symptoms related to dietary factors.

  • Digestive disorders: Conditions like Irritable bowel syndrome (IBS) and Crohn’s disease have been linked to IgG food reactions. Research has shown that 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 reactive foods can 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.
  • Fatigue: Fatigue after eating foods you have sensitivities to is either a sign of increase carbohydrate intake and inability to regulate blood sugar or a food sensitivity.
  • Take the guesswork out of your diet. Since hours or days can pass between the time a reactive food is consumed and occurrence of symptoms, testing is often 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 (remove suspect foods for a period of time and then reintroduce and check for reactions) are difficult to follow and can take months to complete.
  • “Leaky gut,” a term often used colloquially, refers to increased intestinal permeability, a condition where the lining of the gastrointestinal tract becomes more porous than normal. This increased permeability allows various substances, including undigested food particles, to pass through the intestinal barrier and enter the bloodstream. Leaky gut syndrome is thought to be associated with inflammation in the gut lining, a condition known as intestinal inflammation.
  • Several factors can contribute to this inflammation, including food allergies or sensitivities, disturbances in gut flora (dysbiosis), psychological stress, certain medications, and alcohol consumption. The inflammation may compromise the integrity of the intestinal barrier, leading to the leakage of larger molecules, such as undigested food particles, into the bloodstream.

A false food allergy is a non-immunological reaction where a substance in the food triggers mast cells directly, without the involvement of antibodies like IgE. Unlike true allergies, no antibodies are produced in false food allergies. These reactions are specific to particular foods and are not detected through traditional allergy tests.

Food intolerance refers to adverse reactions to food where the involvement of the immune system is uncertain. Skin-prick tests and other allergy tests may yield negative results in cases of food intolerance. While immune reactions cannot be ruled out entirely, they are unlikely to be the major factor causing symptoms. This category excludes false negative IgE allergy tests.

Yes, while traditional allergy tests may show negative results, food intolerance may still involve immune reactions to some extent. The absence of positive results in conventional tests does not rule out the possibility of immune involvement in producing symptoms related to food intolerance.


IgE reactions are immediate and can be life-threatening, often causing symptoms within minutes. IgG reactions, on the other hand, are delayed and may take hours or days to manifest. IgE reactions are commonly associated with allergies like peanuts, while IgG reactions are often identified through testing.
