Although having an allergic reaction after eating a peach is relatively common, the majority of these reactions are not due to the fruit itself. Instead, peaches often carry pollen allergens such as those found in birch trees and ragweed. Known as oral allergy syndrome, the physical effects of an allergic reaction to peaches are typically mild. Despite the low risk of serious, life-threatening allergic reactions, you should avoid peaches if you suffer from OAS.
Oral Allergy Syndrome
Despite the prevalence of peaches in North American food, OAS due to peaches can be difficult to detect. Symptoms typically arise only from the raw fruit, so you may not suffer from any symptoms when eating cooked, canned, processed, baked or microwaved peaches. When eating raw peaches, however, OAS may lead to tingling, itching and swelling in your tongue, lips, throat and palate; watery or itchy eyes; sneezing and a runny nose.
Other Symptoms
While you may not suffer from OAS, peaches can lead to other allergic reactions. Handling or peeling raw peaches, for example, may cause rashes, itching or swelling wherever the fruit comes into contact with your skin. If you are truly allergic to the fruit, you may experience vomiting, cramps, nausea and diarrhea after eating peaches. Due to the rarity of pure peach allergies, it is unlikely that you will experience more severe symptoms. In extreme cases, however, peach allergies can make it difficult for you to breathe and swallow and may lead to the full-body, life-threatening allergic reaction known as anaphylaxis.
Associated Allergies
According to the Internet Symposium on Food Allergens, pure peach allergies are extremely rare. Instead, peach allergies typically accompany allergies to other fruits, pollen and trees. While you are most likely to also suffer from allergies to apples, pears, plums, cherries, nectarines, apricots and birch pollen, an allergic reaction to peaches may be linked to other allergies. As these include ragweed, nut, legume, vegetable and seed allergies, you should consult your doctor for allergy testing before eating raw peaches if you suffer from any of these associated conditions.
Treatment
For very mild allergies, you may not have reactions to peaches that are less than ripe, peeled or fresh-picked. Due to the association between peach and pollen allergies, antihistamines or allergy shots for allergic rhinitis, or hay fever, can be used to treat peach allergies. As OAS typically occurs when eating raw fruit, even brief microwaving or cooking can help you to avoid an allergic reaction. If your reactions continue or you have experienced severe reactions in the past, you should avoid peaches altogether. As you may be at risk of suffering a life-threatening reaction to other foods, you should always carry an emergency medication injection kit (i.e., epinephrine) if you suffer from a severe peach allergy.
