How can I test to see if my insulin increases in response to ingesting x?
This is something you can do to test to see if you brain is going to play tricks on you and secrete some insulin when you eat an artificial sweetener. It doesn’t happen to everyone one and the only way to find out is to test.
What you can do is do a glucose curve and see if you are still at baseline at T30 (the sweetener doesn’t produce glucose in your blood), and then your glucose goes below your baseline at T60 then you probably secreted some insulin in response to the sweetener and you will probably have to restrict use of that sweetener.
