Foods that Assist Getting Relief in COPD

BY Rebi September 3, 2025

If you or a loved one is managing COPD (Chronic Obstructive Pulmonary Disease), knowing which foods can help is just as important as knowing which ones to avoid. The right diet supports lung function, reduces inflammation, and provides energy for breathing muscles. In this detailed guide, we’ll explore foods that assist in getting relief in COPD — based on expert nutrition advice — including what to eat, what to limit, and how to make mealtimes easier.

Foods That Assist Getting Relief in COPD

1. Prioritise Lean, High-Quality Proteins

Protein is vital in COPD care: breathing requires energy, which increases your calorie needs, and protein supports your respiratory muscles.

  • Include lean animal proteins: chicken, turkey, and lean red meat help maintain muscle mass.
  • Add fatty fish like salmon, mackerel or sardines. These provide both protein and anti-inflammatory omega-3 fats.
  • Use plant-based proteins: beans, lentils, soy products (tofu, tempeh) are rich in protein and also bring fiber.

Tip: Aim for 3–5 smaller meals per day instead of just two or three large meals. Eating frequently helps prevent your stomach from becoming too full — which could make breathing harder.

2. Choose Complex Carbohydrates Carefully

Carbohydrates are a double-edged sword in COPD: they provide needed energy, but when metabolized, they also produce more carbon dioxide (CO₂) than fats, which may put pressure on breathing.

  • Favor complex carbs with plenty of fiber: such as oats, barley, quinoa, lentils, beans, and whole-wheat grains.
  • These carbohydrates help with sustained energy and better blood sugar control.
  • However, don’t overdo simple or refined carbs (white bread, sugar-rich foods) as these can lead to rapid changes in blood sugar.

3. Load Up on Antioxidant-Rich Fruits & Vegetables

Inflammation and oxidative stress are key issues in COPD. Certain fruits and vegs help combat these.

  • Berries (like blueberries, strawberries) are packed with antioxidants (flavonoids and anthocyanins) that can help protect lung cells.
  • Leafy greens such as spinach, kale, and other dark greens are rich in vitamins and minerals that support immune function.
  • Bell peppers and citrus fruits are high in vitamin C — an important antioxidant for lung health.
  • Beets and beet greens: these contain nitrates that may improve oxygen utilization and reduce shortness of breath.

4. Healthy Fats That Help, Not Harm

Not all fats are bad — for COPD, choosing the right fats can make a big difference.

  • Use unsaturated fats: olive oil, avocado, nuts & seeds, and oily fish provide anti-inflammatory benefits.
  • Omega-3 rich foods, like flaxseeds, chia seeds and walnuts, may help reduce inflammation in the lungs.
  • These healthy fats also provide a calorie-dense source of energy, which is helpful if breathing is increasing your daily energy expenditure.

5. Potassium and Other Vital Micronutrients

Proper micronutrient intake supports lung muscle function, immune resilience, and overall health.

  • Potassium-rich foods such as bananas, potatoes, tomatoes, and dark leafy greens help maintain lung muscle function and fluid balance.
  • For bone health — especially if you are on steroids — include calcium and vitamin D from sources like low-fat dairy, fortified foods, fish, or supplements (if advised).
  • Zinc and vitamin C (from legumes, spinach, bell peppers) support immunity, which is critical to fighting respiratory infections.

6. Stay Hydrated & Manage Mucus

Hydration is more crucial than you may think:

  • Drink plenty of fluids — 6–8 glasses (or more, as advised by your doctor) helps thin mucus, making it easier to cough up.
  • Choose water, herbal teas, low-sodium broths — avoid sugary sodas or drinks with caffeine.
  • When eating, try small, frequent meals rather than large ones, to minimize the risk of stomach fullness interfering with breathing.

7. Foods to Limit or Avoid

Certain foods may worsen breathing, increase inflammation, or cause gas and bloating — all of which can make COPD symptoms more difficult.

  • Limit sodium: Too much salt causes fluid retention and may make breathing harder. Avoid processed foods, salty snacks, canned soups.
  • Reduce or avoid processed meats: Cold cuts, bacon, sausage have high sodium and preservatives.
  • Be cautious with gas-producing vegetables: Cruciferous veggies (like cabbage, broccoli) can cause bloating, which may press on the diaphragm and worsen breathing.
  • Avoid greasy, fried foods: They can be hard to digest and strain the body.
  • Dairy in moderation: Some people report increased phlegm; choose low-fat options and monitor how your body responds.

8. Practical Tips to Make Nutrition Work for COPD

  • Meal timing matters: Eat your main meal earlier in the day, when you have more energy, and opt for 5–6 small meals rather than a few large ones.
  • Use herbs and spices instead of salt to flavor food: garlic, ginger, lemon, herbs can boost taste and reduce sodium.
  • Prepare simple, nutrient-rich snacks: nuts, berries, yogurt, or whole-grain crackers make for energy-boosting bites.
  • If breathing is very difficult, ask for help in meal prep: sit down when cooking, or involve family/friends.
  • Work with a dietitian: A nutrition specialist with experience in lung disease can customize your nutrition plan based on your symptoms, weight, and treatment.

Final Thoughts

While diet alone can’t cure COPD, choosing the right foods truly helps manage symptoms, improve lung function, and boost quality of life. Foods rich in lean protein, healthy fats, antioxidants, and specific micronutrients support the respiratory system, reduce inflammation, and maintain strength. At the same time, avoiding high sodium, processed foods, and gas-producing items can prevent worsening of symptoms.

By making thoughtful food choices — and combining them with your medical treatment — you’re giving your lungs and your body better support every day.
