I have to hand it to you for not even trying hard enough to read the parent's point about type 2 vs. type 1, and then linking to an article that mentions type 2 in the very first sentance.
doesn't take long to make google searches.
No amount of diet change is going to reverse the damage to the pancreas in Type 1 - it is not a "disease of affluence"
I give up, and suggest you learn to Google something more than just source to try to confirm (poorly!) your own biases about what diabetes is or isn't.
Maybe I shouldn't care, but it is upsetting to have to explain to people all the time. Even more so when they close their ears to the response.
