Uh,oh! Did John Kerry’s Claim of “Signatures” of Sarin Gas Mean Victims Brushed Their Teeth?

Natural News files a report stating that they believe the testing that was used on the alleged victims of Bashar Assad’s sarin gas attack on women and children would also show “signatures” of sarin gas if people drank fluoridated water and/or brushed their teeth. In addition, children’s foods are full of the same “chemical weapons” found in sarin gas.

Is this all a hoax?
