Triggers that can cause allergy symptoms 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 food for pollen, which can cause or aggravate spring and fall allergies. If you have hay fever and have experienced an itchy mouth or throat after eating certain raw fruits or vegetables and some nuts, you may have symptoms of pollen food allergy syndrome, also called oral allergy syndrome. Symptoms of PFAS include an itchy mouth, itchy throat, or swelling of the lips, mouth, tongue, and throat. Occasionally, itchy ears and hives in the mouth are reported.
Symptoms are usually confined to one area and usually do not progress beyond the mouth. It is rare for a patient to have symptoms outside the mouth or anaphylaxis because of it, although it has been described in a very small percentage of patients. Because symptoms usually go away quickly once fresh fruit or raw vegetables are eaten or removed from the mouth, no treatment is usually necessary. If you or your child experiences 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 comes quickly and can lead to death.
In one study, researchers found that PFAS progressed to systemic symptoms in nearly 9 percent of patients and to anaphylactic shock in 1.7 percent of patients. Consult your allergist for more information and to determine if you should carry an epinephrine auto-injector with you to treat possible serious reactions. Avoiding raw foods is the most common way to control this situation. If a food cannot be eaten cooked, for example, if you have significant throat discomfort or difficulty swallowing, or you have systemic symptoms, reactions to cooked foods, or symptoms to high-risk foods, such as peanuts or nuts, your allergist may prescribe an epinephrine autoinjector.
I am sensitive to everything in the list above. It's really hard to find nutritious foods to eat. No corn, soybeans, nuts, grains, lots of vegetables and some meats. Fortunately, there are simple and natural ways, such as changing eating habits, that help treat and alleviate the pain caused by seasonal allergies.
As a result, it is not always easy to identify the disease and link the causative foods to the symptoms they cause. To determine which allergies cause each symptom in each patient, Tobin and several colleagues, including a gastroenterologist, pathologist, and dietitian, track and experiment with patients' diets, in addition to performing the necessary tests. It depends on the pollen allergy, but most foods that cause a pollen-like allergic reaction are usually eaten fresh or raw. A spoonful full of local honey can help relieve watery eyes, congestion and most allergy symptoms, as it contains the same pollen that seasonal allergies come from.
Food pollen allergy syndrome (PFAS), also known as oral allergy syndrome, is caused by cross-reactive allergens found both in pollen and in raw fruits, vegetables, or some nuts. People often consume these foods in combination with others, of course, and the reactions they cause can vary widely and mimic the symptoms of other conditions. In addition, these relationships may mean that you have symptoms similar to those of an allergy when you eat some foods, but you don't test positive on the skin. People also find relief by limiting foods that cause mucus production, such as conventional dairy products and gluten.
