The pulmonary surfactant in our lungs is composed of approximately 90% lipids and 10% protein (Veldhuizen, Nag, Orgeig and Possmayer (1998) and it vital to lung function (Google more about it). When you read the word “lipids,” it means some form of “fats,” and usually saturated fats. Thus, we need good saturated fats in the diet to keep the lungs working well, because lung surfactant is a complex mixture of phospholipids and proteins. Infections can attack the lung surfactant and weaken it.
Saturated fats are found in butter, cream, cheese, coconut oil, bacon and LARD. So, while you are working from home, be sure to eat all the good foods!

The structure of healthy cell membranes, including the lungs and pulmonary surfactant, need good fats as a source of their fatty acid composition. See https://www.ncbi.nlm.nih.gov/books/NBK9898/figure/A1970/
