@ravenup Interesting video, how did you find it? My main concern is the commercials - is this just a long ad for his paid courses and the books he is selling?

The info is good - we already know from extensive studies about the health benefits of green tea, dietary fiber and dark chocolate. But nothing new or earth shattering, and honestly nothing different for lung health than for our health in general. What I would appreciate a lot more is links to the underlying scientific studies showing that this is any different from a good diet in promoting lung health...

If you look at all the dedicated videos about nutrition from NJH (National Jewish Health) and NTM.org, this is a reinforcement of their good advice.
