Aviation

Hari made numerous factually incorrect claims about aviation and its effects on the human body in an August 23, 2011 blog post entitled "Food Babe Travel Essentials – No Reason to Panic on the Plane!" The post has since been removed both from her blog and from the Google cache of the post.

• "When your body is in the air, at a seriously high altitude, your body under goes some serious pressure. Just think about it – Airplanes thrive in places we don’t. You are traveling in a pressurized cabin, and when your body is pressurized, it gets really compressed!"
  • Airplane cabins are pressurized in order to compensate for the dramatic drop in air pressure outside. The cabin pressure is maintained slightly lower than that which most people are accustomed to experiencing on the ground. Therefore, the body is, if anything, somewhat less "compressed" than normal. If the cabin were not sufficiently pressurized, passengers and crew would succumb to hypoxia and lose consciousness or die.
• "The air you are breathing on an airplane is recycled from directly outside of your window. That means you are breathing everything that the airplanes [sic] gives off and is flying through."
  • Cabin air is a mixture of recirculated air and compressed outside air, both highly purified by High Efficiency Particulate Air (HEPA) filters which are very effective at removing bacteria, virus, and other particles. It is replaced constantly by freshly filtered air.
• "The air that is pumped in isn’t pure oxygen either, it’s mixed with nitrogen, sometimes almost at 50%. To pump a greater amount of oxygen in costs money in terms of fuel and the airlines know this!"
  • Humans are accustomed to breathing the mixture of gases in the Earth's atmosphere, which is over 75% nitrogen and less than 25% oxygen. Very oxygen-rich environments greatly increase the risk of fire, as in the Apollo 1 disaster.
