Chronic obstructive pulmonary disease (COPD) is caused due to the inflammation of the lungs and obstruction of air that moves to and from the lungs. It is typically caused because of long-time exposure to lung irritants. Here are some foods that can worsen the condition:

1. Bok choy
Bok choy is one of the food items that can trigger COPD. Despite being a fibrous vegetable and an excellent source of nutrients, bok choy can lead to bloating and excessive gas. This can further make it hard for you to breathe. You should, therefore, consult a dietician or healthcare specialist and limit or stop the consumption of bok choy.

2. Cheese and other dairy products
Dairy products like cheese and milk can cause discomfort to patients with COPD. That’s because dairy products can lead to wheezing and coughing, especially in those who are allergic to dairy. These items may also cause flare-ups in the intestine and increase mucus quantity. They should either be taken in limited quantities or their consumption should be stopped altogether.

3. Chocolate
Chocolate is considered one of the foods that can trigger COPD. It is known to trigger acid reflux, which is why it is advisable that you limit its consumption. Plus, some kinds of chocolate also contain a high amount of sugar, which can further make your breathing difficult.

4. Aerated drinks and foods with preservatives
Aerated drinks and certain foods contain carbon dioxide to be preserved. These have zero nutritive value and may affect the way you breathe. It is for the same reason that such foods trigger COPD, and you should avoid these food items as much as possible.

5. Greasy foods
You probably have a love for pizzas, cheeseburgers, onion rings, French fries, and many other greasy foods. But such items are triggers for COPD. Excessive indulgence in these food items can lead to abdominal discomfort, since these are hard to digest and further lead to bloating. When your belly is bloated, your diaphragm will be pushed, restricting your lung expansion.

6. Salt
Excessive amounts of salt in food items can cause your body to retain more fluids than required. This may increase your blood pressure and, subsequently, cause breathing problems. Of course, you don’t have to completely stop consuming salt; rather, you should discuss the ideal salt intake with your doctor and choose salt products that have less than 140 mg of sodium in every serving.
