Fruits To Avoid During Asthma

Asthma, a chronic respiratory condition characterized by inflammation and narrowing of the airways, affects millions of individuals worldwide. Managing asthma often involves a combination of medications, lifestyle changes, and dietary adjustments. Certain foods, including some fruits, can exacerbate asthma symptoms due to their potential to trigger allergic reactions or other physiological responses. Understanding which fruits to avoid can play a crucial role in minimizing asthma attacks and maintaining respiratory health. This article explores the fruits that should be avoided by people with asthma and why.

Understanding Asthma Triggers

Asthma triggers vary widely among individuals. Common triggers include airborne allergens (like pollen and dust mites), respiratory infections, exercise, cold air, and stress. Dietary triggers, though less commonly discussed, can also significantly impact asthma. Some fruits contain compounds that may provoke asthma symptoms, either directly or through triggering allergic reactions or acid reflux. Identifying and avoiding these triggers is an essential part of asthma management.

Fruits and Asthma: What to Avoid and Why

Citrus Fruits

Citrus fruits, including oranges, lemons, limes, and grapefruits, are often considered healthy due to their high vitamin C content. However, they can pose a problem for individuals with asthma. Citrus fruits are highly acidic and can contribute to acid reflux or gastroesophageal reflux disease (GERD). This acid reflux can worsen asthma symptoms by causing the stomach’s acidic contents to back up into the esophagus, which in turn can irritate the airways. Studies have shown a significant correlation between acid reflux and asthma exacerbations.

People with asthma who also suffer from GERD should be especially cautious about consuming citrus fruits. The acidic nature of these fruits can aggravate the esophageal lining, leading to an increased risk of asthma attacks. While not every asthma sufferer will be sensitive to citrus, it’s wise to monitor consumption if you notice an increase in symptoms.

Dried Fruits

Dried fruits such as raisins, apricots, prunes, and figs are popular snacks due to their long shelf life and concentration of natural sugars. However, they often contain sulfites, preservatives used to maintain freshness and color. Sulfites can trigger asthma symptoms in sensitive individuals, causing wheezing, coughing, and shortness of breath.

The link between sulfites and asthma has been well-documented. Some studies indicate that around 5-10% of asthmatics may be sensitive to sulfites. For these individuals, consuming dried fruits could provoke a significant asthma attack. Reading labels carefully and choosing dried fruits without sulfites or opting for fresh alternatives can help mitigate this risk.


Bananas are another seemingly harmless fruit that may pose issues for some asthma sufferers. This is particularly true for individuals with latex allergies. Latex-fruit syndrome, a cross-reactivity between latex and certain fruits, is a known phenomenon. Bananas contain proteins similar to those found in latex, which can trigger allergic reactions in sensitive individuals.

While not all individuals with latex allergies experience reactions to bananas, those who do might experience itching, hives, or even respiratory issues, including asthma symptoms. If you have a known latex allergy and suffer from asthma, it’s advisable to limit banana consumption.

Apples and Pears

Apples and pears are popular fruits known for their high fiber content and health benefits. However, they can pose problems for people with birch pollen allergies due to a condition known as oral allergy syndrome (OAS). OAS occurs when the immune system mistakes proteins in certain fruits for pollen, causing allergic reactions.

In individuals with OAS, consuming apples or pears can lead to itching or swelling in the mouth and throat. This reaction can be particularly problematic for asthmatics, as it can exacerbate respiratory symptoms. Cooking or peeling the fruits can sometimes reduce the allergenicity, but those with severe allergies should exercise caution.


Melons, such as cantaloupe, honeydew, and watermelon, can trigger allergic reactions in individuals with certain pollen allergies due to cross-reactivity. The proteins in these melons can resemble those found in pollens like ragweed or birch, leading to allergic reactions similar to those experienced with apples and pears.

For asthmatics with pollen allergies, consuming melons can worsen respiratory symptoms. Symptoms of melon allergies can range from mild itching in the mouth to more severe respiratory distress, which can trigger asthma attacks. As with apples and pears, cooking melons may reduce their allergenicity, but caution is advised.


Avocados have gained popularity as a health food due to their healthy fats and nutrient content. However, they can cause allergic reactions in individuals with latex allergies. The cross-reactivity between latex and avocado proteins can lead to symptoms similar to those caused by bananas.

Individuals with latex allergies who also suffer from asthma may find that consuming avocados worsens their respiratory symptoms. While not everyone with asthma will have this sensitivity, it’s important to be aware of the potential risk.


Kiwi is another fruit that may exacerbate asthma symptoms in individuals with birch pollen or latex allergies. Like apples, pears, and melons, kiwi contains proteins that can cross-react with those found in birch pollen. This can lead to oral allergy syndrome, where itching and swelling in the mouth and throat occur after consuming the fruit.

Kiwi allergies can range in severity, with some individuals experiencing mild symptoms and others facing severe allergic reactions. Asthmatics who are sensitive to birch pollen or latex should be cautious when consuming kiwi, as it may trigger or worsen asthma symptoms.


Managing asthma requires a comprehensive approach that includes medication, lifestyle changes, and dietary adjustments. While fruits are generally considered healthy, some can pose risks to individuals with asthma due to their potential to trigger allergic reactions or acid reflux. Avoiding citrus fruits, dried fruits with sulfites, bananas, apples, pears, melons, avocados, and kiwi can help minimize the risk of asthma attacks for those with specific sensitivities.
