The press release (full PDF here) points out one other finding. You know how everyone thinks Mexican Coca-Cola is so much more delicious than American Coke because it is made with table sugar (sucrose), not HFCS? Oops again. The investigators could not find any sucrose in the Coke, but did find plenty of glucose and fructose. This suggests that Mexican Coke is also made with HFCS (or it could also mean that the sucrose had been split into its constituent glucose and fructose).
