Healthy eating – what does it actually mean?
Although there are many different opinions on healthy eating, most people would probably agree that a few basics are undisputed. Vegetables and fruit should certainly feature much more prominently on our menu than pizza and meat. And yet even the “healthiest” foods can be a burden for you in particular if you have a hidden intolerance to them.
In our more than 15 years of practice, we have seen defensive reactions to foods as an increasing, potential health issue. This can also apply to people who eat only one or two meals a day and who, in their view, eat a healthy and balanced diet.
In our experience, food intolerances are a common and underestimated issue. A wide range of illnesses can be associated with such intolerances.
Did you know that your immune system can develop masked intolerances to foods?
In our experience, the complaints caused by food intolerances appear only 4 to 72 hours after eating and are therefore often not linked by patients to their complaints. The causes thus appear to be masked.
The food intolerance test was developed to identify food intolerances individually and to adjust your diet accordingly, step by step.
What are the symptoms of a food intolerance?
Our body can react to one or more foods with unexpected and varied symptoms. The following symptoms can occur in connection with food intolerances:
Abdominal pain
Bloating
Nausea
unwanted weight gain or
weight loss
Inflammation
Pain
Migraine
ADHD
Mental exhaustion
How does the intolerance test work?
In our screening, delayed defensive reactions to 270 foods after eating are detected by testing your blood for antibodies.
The evaluation is usually completed within 10 to 14 days and is then sent to you in a detailed, easy-to-understand format.
The aim is to give you indications of possible causes of your complaints. You receive an easy-to-follow result as well as a practical nutrition plan.
Based on the test result, you can adjust your eating habits. We discuss how to put this into practice together with you.

How are intolerances related to overweight and obesity?
Severe overweight can be based on metabolic disorders. A hidden intolerance can be the cause of disturbed metabolic processes in the body, can favor weight gain and can make it harder for you to lose weight.
Links between overweight and elevated IgG levels were first shown in the study “IgG Antibodies Against Food Antigens are Correlated with Inflammation and Intima Media Thickness in Obese Juveniles” by Wilders-Truschning et al. (ECED published online 2007 – DOI 10.1055/s-2007-993165) .
Can food intolerances be a cause of headaches or migraine?
Primary headaches such as cluster headaches, migraine and tension headaches arise from overexcited cells or overstimulated nerves. Food intolerances can also play a role in primary headaches. The study “Diet Restriction in migraine, based on IgG against food_ A clinical double-blind, randomised, cross over trial” by Kadry Alpay et al 2010 (Cephalalgia 30(7): 829-837, 2010) provides indications of a link between food allergies and migraine.
Gastrointestinal problems and intolerances – what is behind them?
Many of our patients suffer from chronic, unexplained abdominal complaints such as bloating, diarrhea, abdominal pain and/or a feeling of fullness. These symptoms are often accompanied by physical exhaustion and fatigue. Food intolerances can also be among the causes. Food intolerance: specific IgG antibodies against 270 foods
What is the difference between a delayed immunoglobulin G (IgG) food allergy and an immediate allergy (IgE)?
When people speak of a food allergy, they usually mean an IgE allergy with an immediate reaction. In this case, the triggers of the allergy are known. With an IgG food allergy, the reaction is delayed, so it is often not possible to link the triggering food to the symptom that occurs. This is what the IgG food intolerance test is intended for. It can provide indications of possible causes of your complaints. We have been performing the IgG food intolerance test in our practice for 15 years.
Please note:
The immunoglobulin G (IgG) food allergy is not a fact recognized by conventional medicine but an approach from empirical medicine.
How quickly does the gut react to an intolerance?
The time it takes for the gut to react to a food intolerance can vary depending on the type of intolerance and individual factors. Here is some general information on how quickly the gut can react:
Immediate reactions (within minutes to hours)
Food allergies: With true food allergies, which involve the immune system, symptoms can appear within minutes to a few hours after eating the triggering food. Symptoms include abdominal pain, diarrhea, nausea, skin rashes and, in severe cases, anaphylaxis.
Histamine intolerance: In sensitive people, histamine-rich foods can cause symptoms such as gastrointestinal complaints, headaches and skin reactions within minutes to hours after eating.
Delayed reactions (within hours to days)
Lactose intolerance: Symptoms such as bloating, diarrhea and abdominal pain usually appear within 30 minutes to a few hours after consuming dairy products.
Fructose malabsorption: Symptoms such as bloating and abdominal pain can appear within 2 to 6 hours after eating foods high in fructose.
Sorbitol intolerance: Similar to fructose malabsorption, symptoms appear within hours after eating foods containing sorbitol.
Slow reactions (within days)
Gluten intolerance (celiac disease): The symptoms of celiac disease can appear more slowly and develop over days to weeks after eating foods containing gluten. Symptoms can include gastrointestinal complaints, fatigue, skin rashes and nutrient deficiencies.
FODMAP intolerance: With an intolerance to FODMAPs, symptoms can appear with a delay and develop over days after eating certain foods.
Individual differences
The speed and intensity of the reaction to a food intolerance can vary greatly from person to person. Factors that can influence the reaction time include:
Severity of the intolerance: People with more severe intolerances can react faster and more intensely.
Amount of food eaten: Larger amounts of the triggering food can cause faster and more severe symptoms.
Individual sensitivity: Some people are more sensitive to certain foods and react faster than others.
What are the most common food intolerances?
The most common food intolerances involve a variety of foods that can cause unpleasant symptoms in affected people. Here are some of the most common:
1. Lactose intolerance

How can you identify food intolerances?
How You Can Identify Food Intolerances
1. Observe your symptoms
Start by listening to your body and noting the symptoms that appear after eating certain foods. Common symptoms include:
Gastrointestinal complaints (bloating, diarrhea, constipation)
Skin reactions (eczema, redness)
Headaches or migraine
Fatigue and exhaustion
Respiratory problems (nasal congestion, asthma)
2. Keep a food diary
A food diary can help you recognize links between your symptoms and certain foods. Write down:
Everything you eat and drink
The time you ate or drank it
Symptoms that occur and their intensity
3. Elimination diet
An elimination diet can help identify problematic foods:
Remove suspected foods from your diet for 2–4 weeks.
Observe whether your symptoms improve.
Reintroduce the foods one at a time and note whether the symptoms return.
4. Laboratory diagnostics for food intolerances
A more precise way to identify food intolerances is laboratory testing:
IgG antibody tests: These tests measure the IgG antibodies your body produces in response to certain foods.
Breath tests: These tests measure the amount of hydrogen or methane in your breath after consuming certain sugars (e.g. lactose or fructose) in order to detect malabsorption disorders.
Blood tests: Blood tests can detect intolerances to certain foods such as gluten (celiac disease) or histamine.
Skin tests
If allergic reactions are suspected, skin tests can be performed:
A drop of the suspected allergen is applied to the skin and the skin is lightly pricked.
A reaction (redness, swelling) indicates an allergy.
