People suffering from chronic obstructive pulmonary disease, or COPD, should avoid dairy products, cured meats with nitrates, cruciferous vegetables, carbonated beverages, fried foods and sulfites, according to Lung Institute. These types of foods leads to complications for many patients.
Dairy products contain casomophin, which boosts the production of mucus. People who find the elevation of mucus to be a source of discomfort should limit or eliminate dairy from their diet. Milk, cheese, ice cream and yogurt are the most common culprits. Hot dogs, ham, bacon and cold cuts have also been shown to increase the symptoms of COPD, and nitrates cause other health issues as well, notes Lung Institute.
Cruciferous vegetables include Brussels sprouts, cauliflower, broccoli, bok choy and radishes. While these foods provide a wealth of fiber, they also lead to the production of gas, which causes bloating. The result is more pressure on the lungs, causing additional difficulty with breathing. Fried foods also cause bloating and gas. Fried fish and chicken, onion rings, french fries and jalapeño poppers are common foods to avoid, reports Lung Institute.
Shrimp, beer, wine and potatoes commonly contain sulfites to boost appearance and increase shelf life. Sulfites cause narrowing of the bronchial tubes, so COPD sufferers should avoid them, states Lung Institute.
