What is non-specific food intolerance?

Non-specific food intolerance is a complex bodily reaction to certain foods that differs significantly from a classic food allergy.

The main feature of this condition is that the reaction is neither immune-mediated nor enzymatic in nature. This means the body's defense system does not produce antibodies as it does with allergies, and the body simply struggles to process certain chemicals found in food.

Symptoms of intolerance are extremely diverse and often unpredictable; they can manifest in the gastrointestinal tract, skin, or nervous system. The severity of symptoms is often directly related to the amount eaten: a small portion of a product may go unnoticed, while a large one will trigger an acute reaction.

Due to the lack of standard markers in blood tests or skin tests, this pathology is extremely difficult to diagnose using traditional methods. In practice, keeping a detailed food diary is the best method for identifying trigger foods and assessing your individual tolerance.
