Foods to Avoid for Asthma Sufferers: Key Triggers to Watch Out For

Foods That Could Trigger Asthma Attacks and How to Protect Yourself

While no diet can fully cure asthma, managing your food intake can help prevent attacks. Certain foods and beverages may provoke symptoms, especially if you're prone to flare-ups. Carrying a rescue inhaler during outings is recommended. Here are common foods that may trigger asthma episodes in some individuals:


Foods Rich in Sulfites: Dried, pickled foods, and alcohol
These items often contain sulfites, which can cause airway constriction in sensitive asthma patients. Beverages like wine, especially white wine, are high in sulfites that may irritate airways. Additionally, some foods like onions and garlic have sulfites and may contribute to symptoms.

Tea, coffee, and spicy dishes
These contain salicylates, which can trigger intolerance in some asthma sufferers, whether from natural ingredients or additives. Eliminating certain foods may help identify personal triggers.
Beans, cabbage, and fried foods
Such foods can cause bloating and increase pressure on the diaphragm, especially for those with acid reflux issues. This can lead to further asthma symptoms like chest tightness. Avoiding these foods may help reduce flare-ups.

Modifying diet is one approach to managing asthma symptoms, but some individuals might also require medication. Below are common medicines prescribed to control asthma:

FASENRA (benralizumab)
An injectable medication for individuals aged 12 and older, used alongside other asthma treatments. It reduces blood eosinophil levels, which contribute to asthma severity.

DUPIXENT (dupilumab)
An injection-based drug to help prevent asthma attacks. It is not effective once an attack has started. During an ongoing episode, inhalers remain the primary treatment. Additional drugs like NUCALA and Tezepelumab are also prescribed by healthcare providers to prevent asthma attacks.
