Will Microwave Popcorn Ruin My Lungs?

As a child of the ’90s, I’ll forever be a tiny bit terrified of the radioactive potential of microwaves, and standing too close to them. My natural inclination is to watch my food closely, which meant my mother had to tell me to take my face away from the microwave door as soon as I was tall enough to reach it. When I made instant oatmeal or Swiss Miss or the occasional hot Pop-Tart (very different from the toasted Pop-Tart) I would place them in the microwave, step back, and stand a foot to the side of it, like the microwave had peripheral vision I was trying to avoid. I have no scientific knowledge about the radioactive range of the average microwave, but I treat them like the sun: Don’t…

 Will Microwave Popcorn Ruin My Lungs?

Despite the relatively jocular-sounding name, popcorn lung is the nickname given to bronchiolitis obliterans, a condition which causes coughing and shortness of breath—and a condition which is thought to be caused, at least sometimes, by diacetyl—a chemical sometimes used to flavor microwave popcorn.

Bronchiolitis Obliterans (Obliterative Bronchiolitis, Constrictive Bronchiolitis)

Several risk factors can lead to the development of bronchiolitis obliterans. It is one of the most common noninfectious complications after lung transplant and hematopoietic stem cell transplantation. Outside of transplantation, bronchiolitis obliterans can be seen after exposure to inhaled toxins and gases including sulfur mustard gas, nitrogen oxides, diacetyl (used as popcorn flavoring), fly ash and fiberglass. Bronchiolitis obliterans is also associated with autoimmune disorders, especially rheumatoid arthritis and less commonly with inflammatory bowel disease. It is also known to occur after a respiratory viral infection (adenovirus, respiratory syncytial virus), especially in children.

GARD

Bronchiolitis obliterans is an inflammatory condition that affects the lung's tiniest airways, the bronchioles. In affected people, the bronchioles may become damaged and inflamed leading to extensive scarring that blocks the airways. Signs and symptoms of the condition include a dry cough; shortness of breath; and/or fatigue and wheezing in the absence of a cold or asthma.[1][2][3] Many different chemicals (such as nitrogen oxides, ammonia, welding fumes or food flavoring fumes) and respiratory infections can cause lung injury that leads to bronchiolitis obliterans.
