How does food intolerance occur?

The cause of a food intolerance cannot always be clearly clarified. Genetic predisposition often plays a role. There are also three mechanisms that are responsible for food intolerance causing symptoms that negatively affect your well-being :

  • Enzyme deficiency : Sometimes the body lacks a specific enzyme needed to break down certain food components. A well-known example is lactose intolerance.
  • Metabolic disorders : Disturbances in the metabolic process can also occur, which means that food content cannot be processed properly. This includes fructose intolerance.
  • Immune reactions : Food allergies are reactions in which the immune system sees certain proteins in food as harmful and triggers a defensive reaction in the form of an allergic reaction. In the worst case, this can lead to life-threatening reactions.

In addition, some symptoms are sensitive to certain foods. Symptoms of an intolerance to chocolate include diarrhea or stomach pain.

The severity and severity of the symptoms of food intolerance or allergies differ from person to person.


The following complaints often occur
:

  • Digestive problems : These include, for example, abdominal pain or cramps, flatulence, nausea and vomiting. Diarrhea can also occur after eating the problematic food.
  • Skin reactions : Affected people may also experience skin rashes with itching, redness or swelling of the skin.
  • Headaches : Headaches and migraines are also typical symptoms of food intolerance. This is sometimes accompanied by fatigue and lack of energy or problems with the cardiovascular system.
  • Respiratory problems : Severe intolerances can cause breathing problems, such as a stuffy nose or frequent coughing.


Since these symptoms also occur with other illnesses, you should always consult a doctor. This will help you find out whether the symptoms are really due to a food intolerance .


Since symptoms in some cases appear hours or days after consumption, self-diagnosis is usually difficult and expert knowledge is helpful. The correct diagnosis will then help you to change your diet accordingly .

What food intolerances are there?

From digestive problems with soy to an allergy to preservatives to a cow's milk allergy in a baby, many food intolerances are known.


The most common intolerances include the following:

  • Nut allergy : Nuts of any type can cause allergic reactions in some people, ranging from mild skin rashes to severe life-threatening reactions such as anaphylactic shock . For this reason, every product must be labeled if it contains nuts or traces thereof.

  • Gluten intolerance : With celiac disease, the body is sensitive to gluten. This is a protein found in wheat, barley, rye and some other grains. Consuming gluten then leads to an inflammatory reaction in the small intestine. This can lead to digestive problems, for example. It is therefore important to pay attention to your diet if you have celiac disease. If you have symptoms of a wheat allergy , you may also have gluten intolerance.

  • Lactose intolerance : People with lactose intolerance cannot break down milk sugar (lactose) properly because they lack the enzyme lactase. This leads to symptoms such as abdominal pain, bloating and diarrhea after consuming dairy products. Those affected often live vegan lives and have to find an alternative to cream cheese, for example.

  • Fructose intolerance: Another food intolerance is fructose intolerance. In this case, the body cannot absorb and digest fructose properly. In this case, foods containing fructose such as fruit and fruit juice must be avoided.

  • Soy intolerance : In addition, there are people who are sensitive to soy products. Since many vegan substitute products are made from soy, you have to pay particular attention to the ingredients in this case. Examples of alternatives include products made from pea protein.

  • Histamine intolerance : Histamines can be produced during the ripening or fermentation of foods. If you suffer from histamine intolerance, you should not eat histamine-rich foods such as wine. Otherwise, food intolerance causes symptoms such as stomach problems or skin rash.
