What is the most authoritative study of artificial sweeteners?

[Ruken]

Discussion in this thread may interest the OP:

Is this Yale sucralose study legit?

Also the study had equal sweetness and equal or zero carb calories per dose, whereas the proposed sucrose/sucralose does not. Using sucrose instead of glucose does introduce a difference though. I don’t recall seeing any mention of that in the paper. No need for a no-dose control here.
