COPD (chronic obstructive pulmonary disease) is a group of severe lung disorders that triggers breathing difficulties. COPD can cause various complications, such as respiratory infections and worsening symptoms that require healthcare intervention. COPD patients must maintain a healthy immune system to keep infections at bay. A healthy nutritional regime can help boost immunity and overall well-being. Some of the most effective foods that help boost immunity and manage COPD symptoms are discussed below.

Immunity-boosting for COPD patients

Berries
These fruits are high in antioxidants, which can help protect cells from free radicals, which are harmful molecules. Berries like strawberries, raspberries, and blueberries are high in vitamin C, which is essential for immune system health.

Citrus fruits
Citrus fruits, such as oranges, grapefruits, and lemons, are rich in vitamin C and help boost the immune system. Vitamin C is also required to synthesize collagen, a protein that helps maintain healthy skin, cartilage, and bones.

Leafy greens
Green vegetables like spinach, kale, and collard greens are abundant in vitamins A, C, and K and antioxidants. These nutrients can help boost the immune system and reduce inflammation, greatly benefiting people with COPD.

Nuts and seeds
Foods like almonds, sunflower seeds, and pumpkin seeds are high in vitamin E, which is responsible for protecting cells from the damage caused by free radicals. Vitamin E also plays a vital role in the immune system by boosting the activity of white blood cells. Furthermore, nuts are healthy sources of protein that help maintain strong respiratory muscles.

Fish
Fatty fish like salmon, tuna, and mackerel are high in omega-3 fatty acids, which help reduce inflammation and boost the immune system. In addition, omega-3 fatty acids can improve lung function in people with COPD by fighting bacterial infections associated with the condition.

Garlic
Garlic contains compounds like allicin, which have been shown to have immune-boosting properties. Garlic can also help reduce inflammation, lower the risk of respiratory infections, and relax the airways.

Yogurt
This dairy product contains probiotics, beneficial bacteria that can help support the immune system. Probiotics have also been shown to reduce inflammation and improve lung function in COPD patients.

People with COPD can benefit from healthy, nutritious foods with immunity-boosting properties. Berries, citrus fruits, leafy greens, nuts and seeds, fish, garlic, and yogurt can help support and reduce inflammation. It is also advised to seek a nutritionist’s advice to develop a comprehensive management plan for COPD that includes food and exercise suggestions.

Food to avoid for COPD
While eating healthy meals is essential for managing COPD, people with the condition should avoid certain foods that can aggravate the symptoms. Some foods to avoid while dealing with COPD are listed below.

Fried foods
Deep-fried foods, such as French fries, chicken nuggets, and fried fish, are high in saturated and trans fats, both of which can cause inflammation in the body. This inflammation can aggravate COPD symptoms and make breathing more difficult.

Processed meats
Processed meats, like sausages and bacon, are high in saturated fats, trans fats, and sodium, which can worsen COPD symptoms by increasing inflammation. These meats may also contain nitrates, which are linked to causing an increased chance of lung cancer.

Dairy products
Milk products like milk, cheese, and butter can be difficult to digest for people with COPD, leading to increased mucus production and breathing difficulties. Some people with COPD may also be lactose intolerant, which can cause more digestive issues.

Carbonated drinks
Aerated drinks like soda and sparkling water can cause bloating and increase lung pressure, making breathing harder. These drinks can also contain high amounts of sugar, leading to weight gain and inflammation.

Packaged foods
Processed foods like chips, crackers, and cookies are often high in sodium, saturated fats, and added sugars, all of which can worsen COPD symptoms. These foods can also contain additives and preservatives, which can trigger inflammation.

Caffeine
Caffeine can cause dehydration and increase heart rate, which worsens COPD symptoms. Additionally, studies indicate that caffeinated drinks interfere with prescription treatments that help manage COPD symptoms. Therefore, it is advised to avoid such items while dealing with the condition.

Eat healthy food whenever possible. With COPD, breathing uses up to ten times as many calories, so maintaining adequate energy levels can be accomplished by following healthy nutritional habits. People who experience exhaustion and fatigue due to respiratory issues may find eating more frequently and in smaller quantities helpful. Opt for four to six smaller meals throughout the day rather than three larger ones.

Tips for managing COPD symptoms
COPD can cause symptoms such as shortness of breath, coughing, and wheezing, significantly impacting a person’s quality of life. However, several tips can help people manage COPD symptoms and improve their general health.

1. Maintain an active lifestyle: Exercise can help improve lung function, decrease shortness of breath, and boost endurance. Low-impact workouts such as walking, swimming, and cycling can significantly benefit people with COPD.
2. Correct use of inhalers: They are a common treatment option suggested for COPD patients and can help reduce symptoms. To get the treatment’s full benefit, it must be used properly. Patients should consult with their healthcare provider to ensure they use their inhalers correctly.
3. Manage stress: Since stress can cause COPD symptoms, it’s critical to keep stress levels under control. Exercises like yoga, meditation, and deep breathing can help to lower stress and anxiety.
4. Avoid triggers: Some environmental triggers, such as allergens, cold air, and contaminated air, can worsen COPD symptoms. Staying away from these trigger factors is crucial to avoid complications.
5. Get vaccinated: Respiratory infections can worsen symptoms in people with COPD or put them at greater risk for developing them. However, getting vaccinated against the flu and pneumonia can decrease the risk of infection.
6. Eat healthy meals: A healthy meal can help manage COPD symptoms by reducing inflammation and enhancing general health. Foods like fruits and vegetables with antioxidants and anti-inflammatory nutrients can be beneficial.
7. Attending pulmonary rehabilitation: Pulmonary rehabilitation is a program for people with COPD that involves exercise, awareness, and support. It can help to improve lung function, COPD symptoms, and overall quality of life.

Managing COPD symptoms requires a comprehensive approach that includes lifestyle changes, therapy, and support.
