Where the tingling comes from
A tingling mouth or an itchy feeling inside of your mouth after eating a certain food can be caused by a true food allergy, or a phenomenon called the Oral Allergy Syndrome. Food allergies can manifest in a range of symptoms: the slight tingle and itch inside of the mouth is on the milder side of symptoms, but some patients also experience a swelling of the lips, tongue, or throat, which gives way to more severe symptoms like breathing difficulties and sometimes even anaphylaxis.
Food allergies and the Big 8
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 soy.
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 anaphylaxisA severe, potentially life-threatening allergic reaction that can lead to a potentially fatal condition known as anaphylactic shock. It can occur within minutes or several hours after coming into contact with an allergen and is often caused by reactions to medication, food allergens or insect venom., 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.

The oral allergy syndrome explained
Oral allergy syndromeOccurs when proteins of certain foods are similar in structure to allergenic proteins in certain types of pollen. Patients with a pollen allergy experience symptoms of oral allergy syndrome (OAS) in response to eating certain fresh fruits, vegetables and nuts. Symptoms usually include mild swelling and itching of the lips, tongue, inside of the mouth, soft palate, throat and ears. is an IgE-mediated allergic reaction that occurs after eating certain foods. It is typically triggered by plant proteins that cross-react with certain inhaled antigens. The syndrome, sometimes called pollen-fruit syndrome, is caused by a cross-reactionCross-reactions can occur between inhaled pollen and ingested food allergens. A primary sensitization to a pollen allergen, e.g. Birch pollen can sometimes lead to oral allergy symptoms when eating apples, due to the structural similarity of the apple allergen Mal d 1 to the Birch pollen Bet v 1. of allergens found in pollen as well as in raw fruits, vegetables and some tree nuts.
Here is an example: It is possible for patients who are allergic to birch pollen to develop oral allergy syndrome when eating apples. This is a so-called cross-reaction caused by the structural similarity of birch and apple allergens and leads to a tingling, itchy feeling in the mouth. Typically, the symptoms described above occur immediately after eating the food or within 5 minutes at the latest.
Cross-reactions between pollen and foods
Certain pollen are known to frequently cross-react with certain fruits, vegetables, and nuts. Patients allergic to Birch pollen often experience reactions when eating apples, almonds, carrots, celery, cherries, hazelnuts, kiwis, peaches, pears, and plums. Patients allergic to grass pollen often react to celery, melons, oranges, peaches, and tomatoes. Likewise, ragweed pollen can cross-react with bananas, cucumbers, melons, sunflower seeds, and zucchini. Additionally, similarities in dust mite and cockroach allergens and seafood allergens cause similar cross-reactions.
