Food Intolerance Testing

Spread the love

Food intolerance testing can become the most important step in restoring your health and wellbeing.

Food intolerance or sensitivities are very common. They impact your wellbeing and in the long term, they may cause diseases.

It is important to eliminate products that you are sensitive to from your diet. This will help you to restore your health if you already have any chronic diseases.

In this video post, I talk about the tests that I’ve used myself – immunoglobulins and bioresonance tests, as well as the FODMAP diet.

Food Intolerances


Food intolerances are reactions to foods which are much more subtle than allergies. Though they are not life-threatening they can be detrimental for your health and wellbeing.

Food sensitivities can cause dysregulation of your digestion, lead to bloating, abdominal pain, diarrhea, constipation.

Inability to digest one food will affect the ability to digest any food and supply your body with vital nutrients.

Your immune system may react to the non-tolerated food components. Your immune system will be in a constant state of war with the food you eat.

All above can lead to further typical intolerance symptoms like fatigue, headaches, skin irritation, disregulation of menstrual cycle.

A continuous immune response to foods can cause autoimmune diseases, like Hashimoto Thyroiditis. Food intolerances are a known component of Hashimoto’s.


Food intolerances are estimated to affect up to 20% of the total population. But there are no reliable, proven, and established diagnostic methods for food intolerances yet. Also, most people are not aware of food intolerances. And regular doctors are not advising testing for them treating only symptoms.

In my opinion, it is quite natural that everybody is unique and will be sensitive to one or the other product. So, everybody could have an intolerance to one or the other product

Most common are food intolerances to gluten and cow milk. The very fact that grains have been modified to an extreme extent to withstand any weather conditions and any parasites makes them simply indigestible to humans as well.


Immunoglobulin tests

Immunoglobulins are antibodies. Immunoglobulin testing detects antibodies to certain foods in your blood. So, this test shows which products your immune system is fighting.

You can order such a test online and perform it at home. But there are also labs specializing in antibody testing.

They will usually test for IgG and IgE. Though the IgE and IgG tests are praised as a golden standard, any immunoglobulin test is limited to a certain range of products.

My experience

I used such a test a decade ago. It showed sensitivity to gluten and milk products.

After excluding gluten and milk products from my diet I was able to restore my gut health. This was a significant step towards my remission of Hashimoto’s.

Bioresonance hair testing

What is (Not) Known

Bioresonance hair testing is based on measuring the biofield. Biofield technology has been developing in past decades for the diagnostic and therapeutic purposes.

Though interactions with biofields have not been fully understood or proven yet they have been successfully used for treatments of diseases. And biofield technology development has been allowing testing and studying of the biofields.

The biofield contains information about biological processes rather than a chemical composition.

Biofield interactions operate in part via low-energy or “subtle” processes such as weak, nonthermal electromagnetic fields (EMFs).

Biofield interactions may also operate in more well-understood informational processes found in electroencephalographic (EEG) and electrocardiographic (ECG) data.


I chose bioresonance test because:

  • It is non-invasive which makes a huge difference when you test children as I did
  • it covers a very broad spectrum of foods and compounds – foods and non-foods, metal intolerances as well as vitamin and mineral deficiencies
  • the price is low compared to the antibody testing especially if you test the whole family as I did
  • I found (there exist) accredited laboratories that assure high quality of testing

My experience

Because we tested the whole family (four people) I could assess that results were not random at all but reflected our specific personal diets.

1Food intolerances: strong reaction to rye, salmon, lactose

Non-food intolerances: Ficus plant

Deficiences: arginine, molybdenum

Known reaction to rye, wheat, milk from a previous IgG test. Regular consumption of rye and salmon before the test

Exposure to ficus plant. After removing the plant, itching and wound forming under the nose disappeared

A Flexitarian, low protein diet could have caused arginine deficiency. Regular, long-term supplementation with rare metals (selenium and zink) could have suppressed the assimilation of molybdenum.
2Food intolerances: all spices

Deficiences: potassium
Daily consumption of hot spices

Intensive running and sweating lead to loss of electrolytes like potassium
3Food intolerances: milk

Deficiences: creatine, isoleucine, docosahexaenoic acid, vitamin B3, gallic acid

Milk intolerance is the most common among children. This family member used to consume milk in big quantities.

The main source of creatine and isoleucine, docosahexaenoic acid (omega-3 fatty acid), vitamin B3 (niacin) is meat and fish. These deficiencies could have been caused by a vegetarian diet.
Gallic acid has important anticancer activity and comes from onions which are avoided by children.
4Food intolerances: gluten

Deficiences: vitamin B3, zeaxanthin

Gluten sensitivity is highly common and could have been caused by extensive consumption of bread, pasta, and pizza by this family member.

Vitamin B3 deficiency could have been caused by low consumption of meat, especially red meat.
Foods containing the highest amounts of zeaxanthin are dark green leafy vegetables. Those are usually avoided by children, which is especially true for this person. However, zeaxanthin plays important role in eye health.


Bioresonant testing results can be verified by eliminating foods or non-foods like I did with ficus and saw a fast disappearance of the skin irritation.

Metals listed in the metal sensitivities list need to be avoided by water purification, by choosing organic cosmetics and cleaning supplies.


The FODMAP diet has been designed by Monash University to reduce symptoms of irritable bowel syndrome (IBS). About 15% of the world’s population is affected by ABS.

Carbohydrates and sugars

It is a diet based on the elimination principle diet. FODMAP diet tests sensitivities to sugars and short-chain carbohydrates. Fodmaps are:

  • fructose (fruits, honey, etc.)
  • lactose (dairy)
  • fructans (wheat, garlic, onion, etc.)
  • galactans (legumes)
  • polyols (artificial sweeteners)

The foods high on FODMAP can be devided into following groups:

  • eggs, meats, poultry fish
  • dairy
  • non-dairy meat alternatives
  • grains
  • fruits
  • vegetables
  • desserts
  • beverages
  • seasoning and condiments

FODMAP Protocol

Step 1. At the beginning of the diet, all high FODMAP products are excluded from the diet for a period of a few weeks.

During this time you can supplement with high-quality probiotics (or fermented vegetables) and enzymes. This helps you to restore your gut health faster.

Step 2. Then each food group is re-introduced individually. If any of the groups cause digestion problems it is eliminated again. Step 3. Protocol results in a personalized FODMAP diet.

It is not easy to figure out which products in each group are high and which are low on FODMAPs. You can either seek the support of a trained nutritionist, use a list, a book, or a special app to make the right choices. Monash University has developed its own FODMAP app with the FODMAP guide and recipes.


  • Food intolerances can have a detrimental effect on your health and wellbeing, cause chronic diseases.
  • Testing for food sensitivities can restore wellbeing, prevent diseases, and even achieve remission of chronic diseases
  • Immunoglobulin testing is known as a golden standard of food intolerance testing but it can test only a limited amount of products and is expensive.
  • Bioresonance hair testing is not scientifically proven but the results that I received were highly aligned with the diet of each individual person.
  • Bioresonance hair testing covers a wide range of foods, non-foods, and separate compounds. It tests not only for sensitivities but also for deficiencies. There exist accredited laboratories providing quality bioresonance testing services.
  • FODMAP diet is rather complicated. It does not only test for sugars and short-chain carbohydrate sensitivities but is also designed to restore gut health. FODMAP apps can help you with the right choices of foods.
