One diet soft drink daily may increase diabetes risk by more than a third (monash.edu)

New very solid large scale long term review showing that diabeties risk is increased more with daily artificially sweetened beverage than a sugar beverage

Did they account for people who drink diet soft drinks to compensate for eating tons of sugar in all other parts of their diet?

They really seem to downplay the sugary soda -> obesity -> diabetes link, quoting some studies and saying evidence for it is "mixed".

I thought that was fairly solidly documented and this would be one more study on the pile, but they treat the two findings as much more equivalent than I would have expected.
