How Diet Affects Breathing
We’re all aware that diet affects health. But did you know that people with COPD (chronic obstructive pulmonary disease) can help themselves breathe better by making simple changes to their eating habits?
What we eat
The food we eat combines with the oxygen we breathe to create energy and carbon dioxide. Our body needs the energy to function. The carbon dioxide is a waste product we need to dispose of. Too much of it is toxic. But having to exhale a lot can be tiring.
- Limit sugar and sugary foods such as candy, cake, and soft drinks. Carbohydrates (sugars and starch) produce more carbon dioxide than fats or proteins. They make more work for the lungs.
- Fats produce the least carbon dioxide. The best fats are polyunsaturated fats such as vegetable oils and soft margarine (look for those labeled “zero trans fat”).
- Protein is necessary to maintain the respiratory muscles. At least two servings a day is recommended: eggs, dried beans, dairy products, and meats.
- Limit foods that produce gas, such as carbonated beverages, dried beans, cauliflower, and broccoli. They cause the stomach to expand which puts pressure on the diaphragm.
- Limit salt. It can cause the body to retain fluid, making it harder to breathe. See our January 2010 article on reducing salt.
The way we eat
- Consider eating four to six small meals a day and minimizing fluid intake at mealtime. It’s harder to breathe when your stomach is full.
- Eat earlier in the day. If energy is generally low by dinnertime, focus on consuming more of the day’s calories in the morning and afternoon.
As always, check with a doctor or dietitian to determine the diet that is right for your loved one. You can search for a registered dietitian near you at www.eatright.org.
