What influences intolerances?

  • Eating habits

    • Hasty eating, lots of sugar, salt and saturated fats, and monotonous diets can compromise the intestinal barrier and increase the risk of intolerances.
    • A balanced, plant-based diet and conscious eating support intestinal health and a balanced intestinal flora.
  • Stress

    • When stressed, the body releases more stress hormones, which affects digestion and can lead to nausea, abdominal cramps and diarrhea.
    • Relaxation, enough sleep and a balanced diet can alleviate stress reactions.
  • Antibiotics

    • Frequent antibiotic use can eliminate both harmful and beneficial gut bacteria, affecting gut flora and digestion.
    • High-fiber diets and probiotics can strengthen the intestinal flora after antibiotic treatment.
  • Environmental influences

    • Pesticides, processed foods and additives can increase intestinal permeability, allowing contaminants to enter the blood.
    • Eating unprocessed, seasonal and organic foods can reduce exposure to pesticides and additives.
  • Pre-existing conditions

    • In addition to genetic enzyme defects, pancreatic diseases, chronic inflammatory bowel diseases, infections or bacterial colonization can trigger intolerances.
    • Gastrointestinal complaints should be examined and diagnosed by a doctor.

Frequently asked questions

  • Questions about the intolerance test

  • What is an intolerance?

    In the case of an intolerance, the body is not
    the body is not able to absorb certain substances



    to process. This leads to a disturbance in the metabolic process. Intolerances occur particularly frequently in the context of food intolerance. In this case, the intestine usually lacks the necessary enzymes to digest the substance.

  • What is the difference between an allergy and an intolerance?

    Allergies and intolerances are two different forms of hypersensitivity reactions of the body to certain substances. Our intolerance test does not test for allergies.

    An allergy is an immune-mediated reaction to a specific antigen. This results in the production of specific antibodies (IgE) against the antigen. This leads to an inflammatory reaction in the body. Typical symptoms of an allergy are, for example, itching, skin rashes, shortness of breath, dizziness or anaphylactic shock.

    An intolerance is a non-immunological reaction to a substance that can be triggered by various mechanisms. A possible cause may be an enzyme deficiency. These prevent the body from digesting certain substances properly. This produces metabolic products that can lead to symptoms in the body. Typical symptoms of intolerance are, for example, abdominal pain, nausea, diarrhea or flatulence.

    In short, the difference between an allergy and an intolerance lies in the way hypersensitivity is triggered. An allergy is an immune-mediated response to an antigen, while an intolerance is a non-immunological response to a substance.
