Fruits To Avoid During Bronchitis

Bronchitis is a respiratory condition characterized by inflammation of the bronchial tubes, which carry air to the lungs. It manifests in two primary forms: acute bronchitis, which typically resolves within a few weeks, and chronic bronchitis, which persists for longer periods. Common symptoms include persistent coughing, chest discomfort, and difficulty breathing. Diet plays a significant role in managing bronchitis, as certain foods can either alleviate or exacerbate symptoms. In this article, we’ll focus on fruits that should be avoided during bronchitis to prevent worsening the condition.

Why Some Fruits Should Be Avoided During Bronchitis

Diet has a direct impact on inflammation and mucus production, both of which are key factors in bronchitis. Some fruits can irritate the respiratory system or lead to increased mucus production, which can exacerbate coughing and discomfort. Therefore, it’s important to understand which fruits to avoid in order to manage bronchitis symptoms effectively.

Fruits to Avoid During Bronchitis

1. Citrus Fruits

  • Examples: Oranges, lemons, limes, and grapefruits.
  • Reasons to Avoid:
    • Citrus fruits are known for their high acidity, which can irritate the throat and respiratory tract, particularly when they are already inflamed due to bronchitis.
    • The acidic content can trigger excess mucus production, leading to more coughing and discomfort.
    • While they are rich in vitamin C, which boosts the immune system, it’s better to obtain vitamin C from less acidic sources during bronchitis episodes.

2. Bananas

  • Reasons to Avoid:
    • Bananas have a tendency to thicken mucus, which can make it more difficult to expel and can worsen coughing.
    • The soft texture of bananas can stick to the throat, causing additional discomfort when coughing.
    • They can also cause bloating and stomach discomfort in some people, which may further aggravate coughing fits.

3. Pineapples

  • Reasons to Avoid:
    • Pineapples are highly acidic, which can irritate the throat and respiratory lining, particularly in those with bronchitis.
    • While they contain bromelain, an enzyme known for its anti-inflammatory properties, it can also lead to increased mucus production.
    • Consuming pineapple during bronchitis may increase throat irritation and worsen coughing due to its high acidity.

4. Apples

  • Reasons to Avoid:
    • Apples, especially when eaten with the peel, have high fiber content, which can cause bloating and stomach discomfort.
    • The slightly abrasive texture of apple peels can irritate an inflamed throat, leading to more coughing.
    • Although generally healthy, apples can cause more discomfort than relief during bronchitis due to their potential to irritate the throat.

5. Strawberries

  • Reasons to Avoid:
    • Strawberries are high in histamines, which can trigger allergy-like reactions that exacerbate bronchitis symptoms.
    • The acidity of strawberries can increase mucus production, worsening symptoms like coughing and throat discomfort.
    • They are best avoided during bronchitis due to their potential to irritate the respiratory system further.

Alternatives and Considerations

While some fruits can aggravate bronchitis symptoms, there are others that are less likely to cause irritation or mucus production.

Mild Fruits to Consider

  • Pears: Pears have a mild flavor and low acidity, making them less likely to cause throat irritation or excess mucus production.
  • Peaches: Similarly mild and non-acidic, peaches are soft and soothing, making them a suitable choice.
  • Berries (except strawberries): Blueberries and raspberries have lower acidity levels than strawberries and can be consumed safely during bronchitis.

Cooking Methods

  • Steaming or Boiling: Cooking fruits can help break down their fibers, making them easier to digest and less likely to cause discomfort during bronchitis. For example, poaching pears or apples can make them softer and more suitable.

Juicing Caution

  • Concentrated Acidity and Sugars: Juices, particularly from citrus fruits, are highly concentrated in both acidity and sugars, which can lead to increased throat irritation and mucus production. Even less acidic juices should be consumed cautiously, as they can be high in sugars that weaken the immune system.


Managing bronchitis involves understanding the foods that can aggravate its symptoms, especially fruits. Citrus fruits, bananas, pineapples, apples, and strawberries can worsen inflammation, increase mucus production, and irritate the throat. Instead, focus on mild, non-acidic fruits like pears and peaches, and consider cooking methods that make fruits easier to digest. While it’s essential to maintain a healthy diet, being mindful of the fruits to avoid during bronchitis will help you manage the condition more effectively. Consult a healthcare professional for personalized dietary advice, especially if you have chronic bronchitis or other health concerns.
