With references cited to YouTube and NPR, I have trouble trusting anything in this article. Maybe send us to some peer-reviewed study?
Perhaps you can find some references to peer-reviewed studies inside the content of the video. Let me know! When I get some time, I'll watch it again myself.
I'm only about 7 minutes in, but I do also see a reference to Arismendi-Morillo "Int J Biochem Cell Biol" 41, 2062-68, 2009.
I'll keep updating here.
