    Very surprising result, thanks for sharing! Please don’t tell me you have a study coming up that shows iceberg lettuce is better than kale in any application (although I suspect it would be a superior source of water!).

    I too am surprised that shitake mushrooms didn’t come up higher. I’ve read elsewhere that there is some evidence that they are cancer-fighting (although I appreciate you are looking at aromatase inhibitor activity specifically in this segment)

    This is surprising. How many mushrooms do you therefore recommend eating daily? The actual research article mentions mushroom extract.

    Are most mushrooms grown in manure?
    Should I be concerned about contracting a pathogen from particles of manure that may be on the mushroom?
    What is the best way to clean mushrooms?

    Thanks very much for your videos.

    Are the mushrooms better cooked or raw?

    Were these mushrooms tested cooked or raw? Since we now know we should cook them first to avoid toxins…
