Can anyone even figure out what carbonated beverages were used for this study? Was there caffeine in it, etc? Then they say they started with 16 rats but then elsewhere (when it is mentioned at all) they seem to have 4 groups of triplicates. So it looks like 25% of the data floated away. They also don't mention blinding. Those are the type of basic questions you should ask when you read a paper that will lead you to immediately dismiss something like this in under 20 min.
