Fiber may be as good for your lungs as it is for your guts

This article has good information and is fairly short read here, but provides links to studies and what not.

Can’t stop wheezing? Eat some fruit. According to a study published in Nature Medicine (paywall), an increase in dietary fiber could make you less susceptible to allergic asthma attacks.

Found in fruits, vegetables, whole grains and legumes (like beans and lentils), dietary fiber is already an important part of a healthy diet. Fiber is made up of all the plant material a human body can’t absorb, so it isn’t digested. But both kinds of fiber—soluble and insoluble—contribute to a healthy gut. While insoluble fiber passes through the body quickly (which keeps your bowel movements regular), the former attracts water, creating a gel that slows digestion. This makes you feel more full, which contributes to weight loss, and also seems to slow the absorption of “bad” cholesterol.

In the new study, mice who ate more pectin (a soluble fiber) before being exposed to dust mites produced fewer of the immune cells associated with asthmatic inflammation.
