You're likely experiencing Oral Allergy Syndrome (OAS), also known as Pollen-Food Syndrome, where your immune system mistakes similar proteins in raw fruits for pollen you're already allergic to (like hay fever), causing sudden itching/swelling in your mouth/throat, often triggered by birch or grass pollen allergies. It can develop at any age, even to foods you've eaten for years, and heating the fruit usually breaks down these proteins, making cooked fruit safe.
Overview. Pollen Food Allergy Syndrome (PFAS), also known as oral allergy syndrome, is caused by cross-reacting allergens found in both pollen and raw fruits, vegetables, or some tree nuts. The immune system recognizes the pollen and similar proteins in the food and directs an allergic response to it.
Symptoms include hives, itching, trouble breathing, congestion, swelling face, throat, tongue, lips, or another part of the body, abdominal pain, nausea, and dizziness.
While there is currently no known cure for any allergy, there are numerous ways for patients to manage their condition and eliminate many, if not all, symptoms. Avoiding the triggering fruit or vegetable is the best strategy. Antihistamines can also help with symptom relief.
Anaphylaxis causes the immune system to release a flood of chemicals that can cause you to go into shock — blood pressure drops suddenly and the airways narrow, blocking breathing. Signs and symptoms include a rapid, weak pulse; a skin rash; and nausea and vomiting.
Symptoms of a food allergy

The "3-day rule" for allergens means introducing one new allergenic food at a time and waiting 3 to 5 days before introducing another, allowing parents to easily pinpoint which food caused a reaction, though some experts suggest a shorter wait (2-3 days) or even daily introduction for non-high-risk infants, while emphasizing introducing common allergens like peanut, egg, dairy, soy, wheat, tree nuts, and fish early (around 6 months) and regularly (2-3 times a week) to build tolerance and prevent allergies, always starting with tiny amounts and monitoring for signs like hives, swelling, or breathing issues.
There are different types of allergies to fruits, and they can sometimes be serious. Visit your GP if you have symptoms after eating any fruits so that you can understand what is happening, learn how to prevent these reactions, and how to manage your diet or any symptoms.
There is no cure for food allergy. If you have a food allergy, you need to be prepared to treat a severe allergic reaction should one occur. The treatment for a severe allergic reaction, or anaphylaxis, is epinephrine. Your allergist may recommend food allergy oral immunotherapy (OIT).
The eight foods responsible for about 90% of food allergies are milk, eggs, peanuts, tree nuts, fish, shellfish, soy, and wheat. A ninth allergen, sesame, was recently added to this list in the U.S., making it the "Big 9" due to its prevalence and the severe reactions it causes.
Do not eat any foods from the food allergen groups for 6 weeks. Eggs, milk, wheat, seafood (fish and shellfish), soy, peanuts, tree nuts, or any foods or drinks that have traces of these foods. Add 1 food from an allergen group back into your diet at a time. Your dietitian can guide you.
6 Foods That May Trigger Vertigo, Note and Avoid!
Stage one: Mild anaphylaxis is the first stage and can cause symptoms like skin rash or redness, itching or hives. Stage two: Moderate anaphylaxis happens when a person has more widespread and extensive symptoms like skin rash and hives that are spreading or mild swelling in their lips or tongue.
Taylor Swift has severe food allergies to peanuts, tree nuts, dairy, eggs, and peas, requiring extreme caution with food preparation and dining out, even leading to cross-contamination issues like a blender incident with almond milk that contaminated her juice, highlighting the seriousness for anyone with multiple food allergies. Her experiences, including a childhood tree nut allergy (where her dog saved her life) and managing allergies at her own events, underscore her commitment to allergy awareness and safety protocols, says Allergic Living, The International Business Ethics Case Competition, Allergic Living.

The nine leading causes of food allergies identified in the US are milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, and sesame.
Probiotics have also been shown to alleviate the allergic reactions caused by such food allergens.
Even a tiny amount of the allergy-causing food can trigger symptoms such as hives, swollen airways and digestive problems. In some people, a food allergy can cause severe symptoms or even a life-threatening reaction known as anaphylaxis.
Pollen. Pollen allergies are one of the most common allergies in the world. Tens of millions of Americans suffer from Pollen allergies. Pollen is a fine yellow powder that is transported from plant to plant by the wind, birds, insects, and other animals to help fertilize plants.
