Tingling mouth?

Tingling mouth after eating a certain food can be caused by a true food allergy or by oral allergy syndrome (OAS). Food allergies can manifest themselves in a range of symptoms: A tingling mouth is one of the milder symptoms, but some patients also experience swelling of the lips, tongue or throat, leading to more severe symptoms such as breathing difficulties and sometimes even anaphylaxis. Especially in the case of these severe reactions, prior clarification by means of a scientific test including the clarification of cross-reactions can provide safety.

Technically, any food can trigger allergy symptoms. However, statistics show that a group of 8 allergens (sometimes 9 if sesame is included), also known as the “Big 8“, are responsible for most allergic reactions to food. The Big 8 include cow’s milk, hen’s egg, wheat, peanuts, tree nuts, fish, shellfish and soya.

Cow’s milk is responsible for most food allergies in infants. Like cow’s milk, egg is also a very common trigger of food allergies in childhood. Wheat allergy is another common food allergy in children. Fish allergies are more common in adults than in children. Like fish allergies, shellfish allergies are more common in adults than in children. Tree nut allergies tend to persist throughout life and are the most common cause of food-related anaphylaxis, along with shellfish and peanut allergies. Peanuts are one of the most common causes of food allergies in children and adults. Allergies caused by soy products are another common allergy in children, but can also occur in adults.
