Everything you need to know about food intolerance: symptoms, tests and treatment

Food intolerance is a reaction to certain foods that can cause unpleasant symptoms such as stomach ache, nausea and diarrhea. This is different from food allergies where the body reacts with an immune response to certain foods and can be potentially life-threatening.

Do you suspect food intolerance?

If you suspect that you have a food intolerance, it may be a good idea to undergo a food intolerance test. There are several types of food intolerance tests, but the most common are blood tests and elimination diets.

Analysis of antibodies and identification

Blood tests can show reactions to specific foods by measuring antibody levels in the blood after eating the food in question. There are two types of antibodies that can be measured in the blood during a food intolerance test: IgE and IgG. IgE antibodies cause allergic reactions and are not usually involved in food intolerances. IgG antibodies, on the other hand, can cause unpleasant symptoms in food intolerances and are usually measured in food intolerance tests.

Elimination diets involve completely removing certain foods from your diet for a period of time and then gradually reintroducing them to see if symptoms return. This can help identify foods that cause problems.

Common food intolerances

The most common forms of food intolerance are lactose intolerance and gluten intolerance. Lactose intolerance occurs when the body cannot break down lactose, the sugar found naturally in milk products, which can cause symptoms such as gas, bloating and diarrhea. Gluten intolerance, also known as celiac disease, is an autoimmune disease in which the body reacts to gluten protein found in grains such as wheat, rye and barley, which can cause symptoms such as abdominal pain, fatigue and weight loss.

It is important to note that it is not always necessary to carry out food intolerance tests and that symptoms can be improved by simply avoiding the foods that cause unpleasant reactions. It is always best to consult a doctor or dietitian before undertaking an elimination diet or any type of food intolerance test.

Identifying foods that cause unpleasant symptoms can be an important part of maintaining a healthy and balanced diet. If you suspect that you suffer from a food intolerance, a food intolerance test can be a good way to get answers. Always consult a professional before taking any steps to find out which foods cause unpleasant symptoms can be an important part of maintaining a healthy and balanced diet.
