    The last line of your commentary was, itself, worth the viewing of this excellent video! I loved it! Thanks again Dr. Greger for your videos.

    • Michael Greger M.D.

       Thanks for the kind words–I try to add as much humor as I can to these videos. Sometimes it’s easier than other times–like this was one just handed to me :)

    For some context, please check out my blog post Treating COPD with Diet!

  • Teresa

    I laughed out loud at the end of this – but I am passing the info on to my mother, who has COPD after a lifetime of asthma and a diet sadly low in fruits and veggies.

    Is there any way you would do written versions of videos. thank you

  • Aht117

    I have a lot of trouble viewing your videos.  Most will not load.  Could you publish the script as an alternative to viewing the video?  Thanks

      I just wanted to update everyone that we can now read the transcripts of the videos by clicking on the “Transcript” button beneath each video. Hope that helps! :)

    Do any studies show diet having an impact on idiopathic pulmonary fibrosis (IPF)? Thanks so much for the daily videos! We have your date/sweet cherry ice cream about every week!

    • Joel

      I second the request for light on IPF. I’ve a friend with this diagnosis, now advanced to the degree he is scheduled for a lung transplant! 

    • Grandmaw

      This is just one experience and may not mean a thing.  My husband has pulmonary fibrosis and about a year ago, I started making vegetable plates with no meat for dinner.  He still sometimes eats meat sandwiches for lunch but no meat for breakfast.  The last time he went to his doctor, he was told that his pulmonary fibrosis had not changed a bit from the previous checkup. It’s worth a try.

  • LynnCS

    Made me laugh. Unfortunately I came over here to find a topic on COPD to link to a friend who’s husband is suffering. Hope it triggers her and him to improve their diets and forestall the inevitible. Love your posts, so much. I always know I can get some info here. I appreciate how much work goes into all this research. You make a difference in so many lives.

  • Kathryn Polster

    Do you have information on reducing COPD symptoms with diet. I have a client on a plant based diet, but is there more he can do?

    • Ed

      Kathryn you might try Serrapeptase and NAC or N-acetyl cysteine. both are inexpensive and made a world of diffrence with my mother-en-law and her COPD

    • Tommasina

      Kathryn, have you also checked out Dr. Greger’s associated blog post?
      It’s been a while since you asked your question, so I’m curious if your client improved since being on a plant-based diet. Any updates? :)

  • kate

    Is there any literature about asthma being helped by a gluten free diet?

  • realist

    Is there any scientific data or opinion on vegetarian diet and idiopathic pulmonary fibrosis?

    Dear Dr. Greger,

    I’ve recently recovered from an anxiety disorder by changing my diet and exercising, the last 8 years I’ve been fighting alone since I’ve refused medicine(the more I’ve read the more I’ve seen how that was the right decision). I’m now healthier and fitter than ever, however, my father is sick and I’m putting half my daily time into trying to research what I can do to help him…

    He’s got COPD, I’ve got him on a vegan varied diet and have him eating some acai berries. Managed to get him to start running too and he’s loving it.

    There’s a little background I don’t know if it matters, but here’s my question:

    I’ve been trying to access articles on PubMed that relates to his issues which seem helpful. However, the full articles seem hidden and I have no idea how this works. Isn’t all research available to the public? I thought there was some kind of honor-code when it comes to that? Is the only way to pay? Or is there some kind of library or something for this?

    (One of the many articles in question: )

    If you’ve read this far, thank you so very very much, otherwise I’m in great great gratitude towards what you do for us by sharing all this wonderful information on the site.

    Your a hero and a life-saver!

    Thank you

      Hi Vencenti, of course I am not Dr. G! I can say that PubMed articles are not all free, the article you sent link to – is not. One possible workaround is to check your local library for access to the specific journal – it may be available and may not. I do have access to my library database via computer but it does have limited journals and doesn’t have the article you are trying to see.

      • vincenti

        Hi Jacquie, thank you so very much for your answer. However unfortiunate. Do you happen to know why not all research is free? Wouldn’t that dramatically speed up it’s implementation into practice?

        I’m trying to get it through my library but during the summers… their open hours are… odd.

        Thanks again tho!

        • JacquieRN

          My pleasure. Yes, research sharing would be great. However, journals charge for articles so they can make some money. They sell subscriptions so as to exist. However, we are beginning to see more open-access journals that are free for anybody to read, and have no expensive subscriptions to promote. Examples: and
