Alcohol, peanuts, sugar, processed foods, wheat, chocolate, and even the morning cup of coffee are known to act as catalysts for hay fever. People also find relief by limiting foods that cause mucus production, such as conventional dairy products and gluten. PFAS doesn't usually appear in young children. The arrival is more common in older children, adolescents and young adults who have been eating the fruits or vegetables in question for years without any problem.
Toddlers younger than 3 years old don't usually develop allergic rhinitis (hay fever) until they are young children. Hay fever is associated with pollen reactions that cross-react with food. People with PFAS are often allergic to pollen from birch, ragweed, or grass. The diagnosis of PFAS is made after analyzing the patient's medical history and, in some cases, performing skin tests with skin puncture and tests with oral food with raw fruits or vegetables.
It usually only affects the lips, mouth, and throat, and occurs when a person with a pollen allergy eats certain foods, usually raw fruits, vegetables, and nuts. In spring and fall, when airborne allergens are more common, eating certain fruits, vegetables, nuts and seeds can cause the body to mistake a protein in the food for pollen, which can cause or exacerbate spring and fall allergies. People affected by PFAS usually eat the same cooked fruits or vegetables because the proteins are distorted during the heating process and the immune system no longer recognizes the food. If you experience significant throat discomfort or difficulty swallowing, or you have systemic symptoms, reactions to cooked forms of food, or symptoms of high-risk foods, such as peanuts or nuts, your allergist may prescribe an epinephrine autoinjector.
In the case of pollen allergies, many people don't know that allergic reactions can occur because of pollen in food, not just because of substances that float in the air. If you have hay fever and your mouth or throat itches after eating certain raw fruits or vegetables and some nuts, you may have symptoms of food pollen allergy syndrome, also called oral allergy syndrome. In addition, a person may have symptoms with some foods in a group and be okay with other foods in the same group. Keeping a food diary to keep track of the raw fruits and vegetables you eat can help you determine which foods are causing the reaction, so you can eliminate them from your diet or eat them only when they're cooked.
If you or your child experience a reaction beyond the mouth area after eating a fresh fruit or raw vegetable, that food could be considered a risk of anaphylaxis, a serious reaction that occurs quickly and can cause death. Food pollen allergy syndrome (PFAS), also known as oral allergy syndrome, is caused by the cross-reaction of allergens found both in pollen and in fruits, vegetables, or some raw nuts. Oral allergy syndrome (also known as food pollen allergy syndrome) can be seen in patients with pollen allergies who experience itchy mouth and throat, usually when eating fresh fruits and vegetables, such as apples, melons, celery and carrots, but also with peanuts and nuts, such as hazelnuts. The types of pollen a person is allergic to (such as tree pollen, grass pollen, or weed pollen) determine which foods can cause symptoms.
The immune system recognizes pollen and similar proteins in the food and directs an allergic response to the food. In food pollen allergy syndrome (PFAS), a person's immune system thinks that the proteins in some foods are like the proteins in pollen.
