Allergic To Peaches: Symptoms, Causes, And Treatment

Peaches are a sweet and delicious fruit enjoyed by many people. However, some people have frustrating allergic reactions when they eat peaches. Peach allergies are not uncommon and can manifest in a variety of ways, including symptoms that range from mild to severe. When someone with a peach allergy eats the fruit, they may experience symptoms within a few minutes and up to 2 hours after eating the fruit.

Common symptoms of peach allergies include mouth tingling or itching (seen in oral allergy syndrome described more below), hives, itchy skin, and swelling, usually in the face, lips, tongue, or throat. More severe reactions are less common and can involve congestion, wheezing, or trouble breathing. It is important for those who suspect they have a peach allergy to be aware of their symptoms and seek appropriate health care advice.

Peach Allergy Overview

Peach allergy is a common type of fresh-fruit allergy, especially in Europe and the Mediterranean area. The severity of the allergy varies among individuals, and the clinical manifestations can range from mild oral symptoms to anaphylaxis, depending on their individual allergic sensitization profile.

Peach Allergy Symptoms

People with peach allergies generally have symptoms within a few minutes to two hours after consuming the fruit. The most common symptom is throat or mouth itching and tingling of the mouth and this type of reaction is usually related to a cross-sensitization from pollen allergy. Some patients can also get itchy skin and hives as well as swelling in the lips, tongue, face or throat. .Less commonly, patients may experience gastrointestinal symptoms such as abdominal pain, cramping, nausea, diarrhea, or vomiting, as well as respiratory symptoms such as cough, wheezing, and chest tightness not related to a cross-sensitization from pollen allergy.

Causes Of Peach Allergy

Peach allergy is often linked to oral allergy syndrome (OAS), sometimes called pollen food allergy syndrome (PFAS), which occurs when the body’s immune system reacts to proteins that are found both in a certain pollen and in peach. . This means that individuals with this pollen allergy may be more susceptible to developing mild reactions to peach.Another factor associated with peach allergy is hypersensitivity to mugwort. Patients who have a mugwort allergy may experience cross-reactivity with peach and other related fruits and vegetables. Mugwort is a common name for several species of aromatic flowering plants in the genus Artemisia

Oral Allergy Syndrome

Oral allergy syndrome (OAS) is a condition in which individuals have an allergic reaction to proteins found in certain fruits, vegetables, or nuts. People with OAS may experience itchiness, tingling, or swelling in their mouth or throat after consuming raw peaches. This condition is more common in individuals who suffer from pollen allergies, as the proteins found in peaches can cross-react with pollen proteins as mentioned above.  A cooked form of the item usually diminishes or eliminates the symptoms for this type of allergy.  

The Relationship Between Stone Fruits & Birch Tree Pollen

Stone fruits, also known as drupes, are a type of fleshy fruit that have a thin skin and a large seed, or pit, in the center. Some common examples of stone fruits include peaches, plums, cherries, mangoes, and apricots. They are in season starting in early spring and continue through early fall. People with a birch tree pollen allergy may experience oral allergy syndrome (OAS) when they eat these types of fruits. 

Diagnosis Of Peach Allergy

Diagnosing a peach allergy involves various tests to determine the specific allergen responsible for the symptoms. These tests include skin tests, blood tests, and oral food challenges.

Skin Test

The skin test, also known as the prick test, is a common method used in diagnosing food allergies. In this test, a small amount of the suspected allergen is placed on the skin, usually on the forearm or back. The skin is then pricked to allow the allergen to enter the body, and the area is observed for any signs of an allergic reaction. A positive reaction, in the form of swelling or redness, indicates an allergy to the tested substance.

Blood Test

A blood test can also be helpful in diagnosing food allergies. This test measures the level of allergic antibodies, called Immunoglobulin E (IgE), in the bloodstream. Blood samples are taken and analyzed for specific IgE antibodies associated with various food allergens, such as those found in peaches. If the test results show increased levels of these antibodies, it indicates a possible allergy to the tested allergen.

Oral Food Challenge

For a more definitive diagnosis, an oral food challenge can be conducted under strict medical supervision. During this test, the patient is given increasing doses of the suspected allergen, in this case, peach, while being closely monitored for any signs of an allergic reaction. If symptoms occur, the test is stopped, and the patient’s allergic reaction is treated accordingly.

An accurate diagnosis is essential for proper management of peach allergy and avoiding potential triggers. It is crucial to consult a healthcare professional experienced in food allergy diagnosis and management to ensure the most accurate results and appropriate treatment plan.

Unfortunately, for peach lovers, one of the primary treatments for peach allergy is avoidance. This means not eating peaches and being aware of related allergens to steer clear of them. It’s essential to read food labels and be cautious when dining out, asking about potential peach ingredients in dishes.

Being mindful of cross-contamination is crucial for those with severe peach allergies. This is more likely in places like a salad bar where tongs may be used across different salad products. Practicing good food hygiene at home is also essential to prevent exposure to allergens. Finally, working with a doctor or allergist can help you develop a comprehensive plan to manage your peach allergy. This plan may include carrying an epinephrine autoinjector for emergencies or discussing strategies to minimize your risk of exposure to peaches and related allergens.

Cooked Peach Vs Raw Peach

Patients with oral allergy syndrome can have difficulty tolerating raw peaches, but  may be able to consume cooked peaches without showing adverse reactions. This is because the heat from cooking may change the proteins responsible for triggering the allergy, making them less likely to cause an allergic response.

Peach skin can also be more irritating when raw as well. Intolerance to other raw fruit may also be present. 

For patients with oral allergy syndrome (who are usually not at higher risk for severe allergic reactions), eating cooked peaches, removing the skin or drinking water after consuming raw peach can help lessen or eliminate the symptoms.  If you have mild symptoms, you can discuss with an allergist how best to manage symptoms in the event of exposure as an EpiPen is usually not necessary in these cases. 

Allergy Shots

Allergy shots for those with pollen allergies can be offered for severe environmental allergies but may or may not help eliminate the peach allergies caused by the cross-sensitization with birch pollen.  Discussing with a specialist if this may be something that would be helpful would be a good idea.

Emergency Treatment

People with a known or suspected peach allergy should develop an emergency action plan with their allergist or healthcare provider. This plan may include carrying an epinephrine auto-injector for those at risk for anaphylaxis and informing close friends, family, and coworkers about the allergy to ensure prompt assistance during an emergency.

Prevention Strategies

One of the most effective prevention strategies for peach allergies is to simply avoid consuming or coming in contact with peaches or peach-containing products. For those who may be able to tolerate peaches if they are cooked or peeled, practicing these methods can help reduce the risk of a reaction.

Living With A Peach Allergy

Managing a peach allergy requires diligence and awareness, but with the right approach, individuals can live a healthy and fulfilling life free from the risk of allergic reactions. This section will provide guidance on essential aspects of living with a peach allergy, including reading food labels, dining out, and creating a support network.

Label Reading

Being diligent about reading food labels is crucial for individuals with a peach allergy, as peaches can be present in a variety of products. Pay close attention to ingredients lists and allergen warnings.

Eating Out

When dining out, always inform the restaurant staff about your peach allergy and inquire about the ingredients used in dishes. Many restaurants are willing to accommodate guests with allergies and can suggest menu items that are safe to consume. In some cases, they may offer to prepare your meal separately to avoid cross-contamination. Highly allergic individuals need to be very careful when eating out and get detailed information about what foods are used in the cooking process.

Allergy To Peach: Symptoms, Causes, And Treatment: Summary

The birch-pollen allergy is more common than many people think. In most cases patients will get an itchy mouth from eating things like raw peaches or raw apples, but it is not extremely common to have a serious reaction. Allergic symptoms in the pollen-food allergy syndrome are largely oral, have a rapid onset, and sometimes this is called oral allergy syndrome. In rare cases when a patient has several facial swelling or difficulty breathing, immediate medical attention is warranted. Allergy shots which can be helpful for environmental allergies do not help as much with fruit allergies.

Avoiding raw peaches is likely to be the most successful way in managing this type of  allergy to peaches. Another important strategy is to be aware of cross-reactivity with other fruits, as some people may also have reactions to similar fruits such as apples or nectarines. Heating peaches can break down the proteins responsible for allergic reactions in some cases and this can allow some patients to still eat peaches in some capacity.
