What Foods Should You Avoid if You Have Pollen Allergies?
People suffering from allergies to pollen and other forms of weeds have to be concerned about more than just the air they’re breathing. People with pollen allergies must also be mindful of the foods they’re eating if they wish to keep their symptoms at bay. The problem lies in the pollen–not the food itself.
These people are not actually suffering from food allergies but are experiencing what is referred to as Oral Allergy Syndrome (OAS). This cross-reactivity occurs when your body mistakes certain proteins found in fresh fruits and vegetables for the allergens in pollen, triggering an allergic reaction even if you’re not specifically allergic to that food. The symptoms of OAS are typically mild for most people–slight swelling around the mouth and in the throat. Understanding cross-reactivity between different types of pollen and foods can help you manage your allergies more effectively.
Pollen-Food Allergy Syndrome (PFAS) is a condition that occurs when individuals are allergic to certain foods and also have an allergy to pollen. Symptoms from PFAS can range from mild, such as an itchy throat and sneezing, to more severe reactions such as difficulty breathing or anaphylaxis.

What are Pollen Allergies?
Pollen allergies, also known as hay fever, are caused by an immune system response to airborne particles from trees, grasses, and weeds. Symptoms of pollen allergies include sneezing, runny nose, itchy eyes, nasal congestion, and wheezing. People with pollen allergies should avoid foods that share common proteins with their allergen. These cross-reactive proteins can cause an allergic reaction and the symptoms of pollen allergy to worsen. Common foods to avoid include apples, carrots, celery, kiwi, peaches, and tomatoes. In addition to avoiding these foods, individuals with pollen allergies should stay indoors on days when the pollen count is high to reduce their exposure to allergens.
Types of Food to Avoid with Pollen Allergies
If you suffer from pollen allergies, it’s important to know which foods can worsen your symptoms. There are several types of food that should be avoided if you have a pollen allergy. Foods like apples, carrots, celery, kiwi, peaches, and tomatoes contain proteins that are cross-reactive with the allergens–causing your hay fever symptoms. This means that eating these foods may cause an allergic reaction and make your symptoms worse. It’s best to avoid these foods altogether if you have a pollen allergy. By following this advice, you can help keep your pollen allergy symptoms under control.
Allergic Rhinitis
Allergic rhinitis, commonly known as hay fever, is an allergic reaction that affects the nose and eyes. It is caused by an allergic reaction to pollen or other allergens such as dust and pet dander. Symptoms of allergic rhinitis may include sneezing, runny nose, itchy eyes and throat, congestion, coughing, and watery eyes. Treatment for allergic rhinitis usually involves avoiding the allergen that triggers the reaction and taking medications such as antihistamines or nasal sprays to reduce symptoms. In some cases, immunotherapy (allergy shots) can be used to help reduce sensitivity to the substances causing the allergies. Taking steps to reduce exposure to allergens by keeping windows closed when pollen levels are high and using air filters can also be beneficial in managing allergic rhinitis.
Foods that Can Trigger Allergic Rhinitis
Certain foods can trigger allergic rhinitis, even if you don’t have a food allergy. Eating certain fruits and vegetables that contain allergens like pollen can cause an allergic reaction in people who are sensitive to these allergens. These include apples, bananas, carrots, celery, cherries, kiwi fruit, and tomatoes. Additionally, eating raw honey or bee pollen can also trigger an allergic response. Foods with added sulfites such as processed meats and canned vegetables may also worsen symptoms of allergic rhinitis.
To reduce the risk of experiencing an allergic reaction from food triggers, it is important to avoid the foods listed above when possible. If you do eat them, try to consume them cooked or peeled and limit your intake. Additionally, talk to your doctor about medications such as antihistamines or nasal sprays that may help manage your symptoms if you experience an allergic reaction after consuming a trigger food.
Pollen-Food Allergy Syndrome (PFAS) Symptoms from PFAS Foods to Avoid with PFAS Conclusion
There are certain foods that should be avoided if you have PFAS. These include fruits and vegetables that contain high amounts of pollen, such as oranges, apples, peaches, tomatoes, peppers, and squash. Additionally, beans and peanuts should be avoided in their raw form.
It is important for those with PFAS to speak with their doctor about what foods they should avoid to reduce the risk of a reaction due to cross-reactivity between allergens present in both food and pollen sources. Eating cooked versions of these foods or opting for frozen or canned options can also help reduce your risk of experiencing symptoms.
Cross-Reactivity and Cross-Reactivity Reactions
Cross-reactivity occurs when the body’s immune system mistakes a harmless substance (such as a food) for an allergen, such as pollen. A cross-reactivity reaction can occur when the proteins found in certain foods are similar to those found in pollen, triggering an allergic response. Cross-reactivity reactions can range from mild to severe and may include itching, hives, swelling, and difficulty breathing. If you have pollen allergies and experience any of these symptoms after eating certain foods, it is important to speak with your doctor for proper diagnosis and treatment. Keeping a food diary can also help identify which foods cause your
Foods to Avoid with Cross-Reactivity Reactions
If you have pollen allergies, there are certain foods that you should avoid to prevent cross-reactivity reactions. Fruits and vegetables should be eaten cooked rather than raw, as the cooking process can help reduce the risk of a reaction. Additionally, processed and reheated foods can also cause reactions and should be avoided when possible. Some common allergens that may trigger a reaction include celery, apples, cherries, carrots, hazelnuts, peanuts, and wheat products. Eating these foods can cause symptoms such as itching, hives, swelling, and difficulty breathing. Taking an antihistamine before eating may help reduce your symptoms if you do consume any of these items. It is important to speak with your doctor if you suspect that a certain food is causing a reaction so they can properly diagnose and treat your condition.

Pollen allergy sufferers should stay away from certain nuts and seeds like peanuts or sunflower seeds.
What Foods Trigger Pollen Allergies?
Fruits and vegetables like melons, bananas, and cucumbers may induce a reaction if you have pollen allergies due to similar protein structures. Other foods that may cause an allergic reaction include apples, carrots, celery, and potatoes. People with a birch pollen allergy may be sensitive to almonds or hazelnuts.
