From the video description:
Back in 2011 the Food Babe published a blog post which she has since deleted called ‘Food Babe Travel Essentials – No Reason to Panic on the Plane!’ but as we all know nothing is truly deleted from the internet. The post is by far one of her strangest but it is also incredibly revealing. This is because for the first time we are seeing her true level of knowledge, paranoia, and lack of common sense. This is because she wrote this in a vacuum, isolated from the internet and those who would correct her. You see, she wrote this post as she was flying from Los Angeles to Tokyo and presumably did not have any internet to fact check any of the claims she was making – and boy oh boy does it make for an interesting read. She seems to think that we breath pure oxygen and the airlines pump in “nitrogen, sometimes almost at 50%” because it cost less money.
