7 Foods to Avoid with COPD for Better Breathing

What is COPD?

Chronic Obstructive Pulmonary Disease (COPD) is a term that encompasses several progressive lung diseases, primarily including emphysema and chronic bronchitis. JAMA Network Open reports that, globally, the prevalence of COPD in 2020 was estimated at 10.6% for both men and women, equating to approximately 480 million cases. This condition obstructs the airflow, making it difficult for individuals to breathe. 

The obstruction is usually due to long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. According to the NHS, smoking is the leading cause of COPD, accounting for approximately 9 out of 10 cases. However, non-smokers can also develop COPD due to environmental factors or genetic conditions.

Impact on Lung Function and Breathing

COPD significantly affects lung function by causing the airways to become inflamed and narrowed. In emphysema, the air sacs (alveoli) at the end of the smallest air passages (bronchioles) in the lungs are destroyed. This reduces the surface area of the lungs and, in turn, the amount of oxygen that reaches the bloodstream. 

Chronic bronchitis involves inflammation of the lining of the bronchial tubes, which carry air to and from the air sacs. This inflammation leads to the production of large amounts of mucus, causing further blockage of the airways.

Symptoms of COPD include:

• Chronic cough
• Shortness of breath, especially during physical activities
• Wheezing
• Chest tightness
• Frequent respiratory infections
• Fatigue

These symptoms often worsen over time, making daily activities increasingly difficult. For example, simple tasks like walking upstairs or carrying groceries can become exhausting. As the disease progresses, patients may find themselves increasingly dependent on oxygen therapy.

Importance of Managing COPD Through Lifestyle Changes

Managing COPD effectively requires a combination of medical treatment and lifestyle changes. Among these, diet plays a crucial role:

• Healthy Eating: A balanced diet can help maintain overall health and support lung function. Avoiding certain foods can reduce COPD symptoms and improve quality of life.
• Staying Hydrated: Drinking plenty of fluids helps keep mucus thin and easier to cough up.
• Avoiding Triggers: Identifying and avoiding food and environmental triggers can prevent symptom flare-ups.

Incorporating lifestyle changes is essential for managing COPD:

• Regular Exercise: Helps improve overall fitness and lung capacity.
• Quitting Smoking: The most crucial step for anyone with COPD.
• Breathing Exercises: Techniques like pursed-lip breathing can help manage breathlessness.

7 Foods to Avoid with COPD

Managing COPD effectively involves understanding which foods can exacerbate symptoms and which ones can help mitigate them. 

Here are 7 foods that COPD patients should avoid to maintain better lung function and breathing:

1. Fried Foods

Fried foods are a staple in many diets, but for people with COPD, they can cause significant issues. The high fat content in fried foods can lead to bloating and indigestion, making it harder to breathe. Additionally, these foods often contribute to weight gain, which can put extra pressure on the lungs and diaphragm. Here’s what to avoid:

• French fries
• Fried chicken
• Onion rings
• Doughnuts

Recommendations: Opt for baked or grilled alternatives. Instead of frying, try roasting vegetables or grilling lean meats. Use healthy oils, such as olive oil, sparingly.

2. Salty Foods

Excessive salt intake can cause the body to retain water, leading to bloating and fluid buildup, which can exacerbate breathing difficulties in COPD patients. High sodium levels are particularly problematic as they can increase blood pressure and strain the heart and lungs. Here’s what to avoid:

• Chips
• Salted nuts
• Canned soups
• Processed meats

Recommendations: Use herbs and spices to flavor food instead of salt. Look for "low sodium" or "no salt added" labels. Prepare meals at home using fresh ingredients to control sodium levels.

3. Dairy Products

Dairy products can increase mucus production, which is problematic for COPD patients who already struggle with excess phlegm. The presence of casomorphine, a byproduct of milk digestion, can lead to thicker mucus and more frequent coughing. Here’s what to avoid:

• Milk
• Cheese
• Yogurt
• Ice cream
• Butter

Recommendations: Switch to non-dairy alternatives like almond milk, soy milk, or oat milk. Use dairy-free products in cooking and baking to reduce mucus production.

4. Carbonated Beverages

Carbonated drinks can cause gas and bloating, increasing the pressure on the diaphragm and making it harder for COPD patients to breathe. The carbon dioxide in these drinks leads to an uncomfortable buildup of gas in the stomach. Here’s what to avoid:

• Sodas
• Sparkling water
• Energy drinks

Recommendations: Stay hydrated with water, herbal teas, and non-carbonated juices. Avoid drinks with artificial sweeteners and preservatives, which can also be harmful.

5. Processed Meats

Processed meats often contain high levels of nitrates and sodium, both of which can worsen COPD symptoms. Nitrates are used as preservatives but can damage lung tissue and increase inflammation. You should avoid:

• Bacon
• Sausages
• Hot dogs
• Deli meats

Recommendations: Choose fresh meats and prepare them at home. Look for nitrate-free and low-sodium options if processed meats are unavoidable. Plant-based protein sources, such as beans and legumes, are good alternatives.

6. Cruciferous Vegetables

While cruciferous vegetables are healthy and rich in nutrients, they can cause gas and bloating. This can make breathing more difficult for COPD patients, as the bloating adds pressure to the diaphragm. Here’s what to avoid:

• Broccoli
• Cauliflower
• Cabbage
• Brussels sprouts
• Kale

Recommendations: Eat these vegetables in moderation and ensure they are well-cooked, which can reduce their gas-producing properties. Incorporate other vegetables like carrots, spinach, and sweet potatoes into your diet.

7. Coffee, Chocolate, and Other Heartburn Triggers

Many COPD patients also suffer from GERD (gastroesophageal reflux disease), which can worsen COPD symptoms. Foods and drinks that trigger heartburn, such as coffee, chocolate, and acidic foods, can increase the risk of acid reflux. You should avoid:

• Coffee
• Caffeinated tea
• Chocolate
• Mint
• Spicy foods

Recommendations: Limit or avoid foods that trigger heartburn. Opt for decaffeinated teas and avoid late-night snacking to reduce the risk of acid reflux. Elevate your head while sleeping to prevent nighttime symptoms.

Recommended Foods for COPD

In addition to avoiding certain foods, it is essential for COPD patients to incorporate foods that can help manage their symptoms and improve overall health. Here are some recommended foods that can support lung function and general well-being:

• Fruits and Vegetables: Fruits and vegetables are rich in vitamins, minerals, and antioxidants, which can help reduce inflammation and support immune function. Examples are berries (blueberries, strawberries, raspberries), citrus fruits (oranges, lemons, grapefruits), leafy greens (spinach, Swiss chard), carrots, and bell peppers.
• Lean Proteins: Protein is crucial for maintaining muscle strength, including the muscles used in breathing. Opt for lean protein sources to avoid excess fat intake. Foods such as chicken breast, turkey, fish (salmon, trout, mackerel), and legumes (beans, lentils, chickpeas).
• Whole Grains: Whole grains provide essential nutrients and fiber, which can help maintain energy levels and digestive health. Include oats, quinoa, brown rice, whole wheat bread, and barley.
• Healthy Fats: Healthy fats are essential for overall health and can help reduce inflammation. Include sources of omega-3 fatty acids in your diet. Examples to Include can be avocados, nuts and seeds (almonds, chia seeds, flaxseeds), oliv,e oil and fatty fish (salmon, sardines).
