-You're a referring to a study done on MICE.
-The finding of that study was a LINK to impaired glucose intolerance.
-You said "They [soft drinks] all raise your blood sugar whether or not they're sugar free."
-You're using personal anecdotal (and far from proven) evidence to support your statement.
The findings you mentioned around diet sodas are weak at best, and you're making a blanket statement to a new member with poor supporting evidence. I find that a bit concerning.
We are all here to help each other but it's important to be specific when discussing what works for you and what works for most.
Short answer: For the overwhelmingly vast majority (type 2 and type 1 alike), diet sodas will have no effect on mood sugar levels. That is easily supported by our bodies' inability to convert most common artificial sweeteners into glucose.
