Adverse reactions to food affect approximately one third of the population. They are based on very different mechanisms and are divided into food intolerances, which manifest mainly in the gastrointestinal tract, and food allergies, which can also cause extraintestinal symptoms and have an immunological genesis. The most common food allergies in adults are pollen-associated allergies to cereals or pome and stone fruits, while allergies to peanut, milk and egg are particularly common in children. The diagnostics of food allergies are complex and therapy is primarily based on targeted elimination diets. This advanced education article focuses on food allergies with gastrointestinal symptoms. © 2022. The Author(s).
