Understanding Asthma: How Nutrition Can Play a Role in Managing Symptoms

Asthma is a chronic respiratory condition that affects the airways, causing inflammation and narrowing, making it difficult to breathe. It is a widespread condition, with approximately 7-10% of the global population affected. In the UK alone, around 5.4 million people receive treatment for asthma, highlighting the significance of proper management strategies.

Common Symptoms of Asthma:

• Shortness of breath

• Wheezing or whistling sound when breathing

• Chest tightness or pain

• Chronic coughing, especially at night or early morning

• Increased mucous production

• Difficulty breathing during physical activity or exposure to triggers

Root Causes of Asthma

Asthma is often linked to a combination of genetic and environmental factors. A family history of asthma or allergies increases the likelihood of developing the condition. Environmental triggers such as air pollution, allergens (dust mites, pollen, pet dander), respiratory infections, and exposure to cigarette smoke can exacerbate symptoms. Additionally, diet and gut health have been increasingly explored as potential contributors to inflammation and immune system regulation, which may influence asthma severity.

How GPs Support Asthma Management

General practitioners (GPs) play a vital role in asthma care by:

• Diagnosing asthma through lung function tests and symptom assessments

• Prescribing medication such as inhalers (bronchodilators and corticosteroids) to manage symptoms

• Advising on lifestyle modifications to reduce exposure to triggers

• Offering asthma action plans and regular check-ups to monitor and adjust treatment as needed.

  

A Nutritional Approach to Asthma Management

A nutritionist can offer a step-by-step approach to support individuals with asthma through dietary and lifestyle adjustments:

1. Identify Potential Triggers – Assess food intake to identify potential allergens or inflammatory foods, such as dairy, processed foods, or food additives, that may worsen symptoms.

2. Support Gut Health – Introduce probiotic and prebiotic-rich foods (such as yoghurt, kefir, and fibre-rich vegetables) to promote a healthy gut microbiome, which plays a role in immune function.

3. Increase Anti-Inflammatory Foods – Encourage the intake of omega-3 fatty acids (found in oily fish, flaxseeds, and walnuts), turmeric, ginger, and leafy greens to help reduce inflammation in the body.

4. Boost Antioxidant Intake – Include a variety of colourful fruits and vegetables, particularly those rich in vitamin C and E, to support lung function and combat oxidative stress.

5. Monitor Nutrient Deficiencies – Assess levels of vitamin D, magnesium, and zinc, which have been linked to respiratory health and may play a role in asthma management.

6. Encourage Hydration – Ensure adequate water intake to help thin mucus secretions and maintain airway hydration.

7. Create a Personalised Plan – Develop a tailored dietary and lifestyle strategy that aligns with the individual’s needs, preferences, and response to dietary changes.
