@joycecates I don’t think Pulmonologists have time to educate their patients. I may a bit jaded. They are dealing with crowds of people with breathing issues . There are millions of people suffering from COPD. There are millions that will be learning that they are affected . The pulmonologist realizes the problem is usually non reversible damage . I think, if they give a couple hints on what to eat or drink, it is probably what a patient told them was a help for them personally . There are lots of articles on the internet about diet and COPD. Not all of them are relevant to everyone . It’s kind of like mining , lots of material to dig . Some information is helpful , some not so much .
