Does anybody know what the science says about the impact of stevia on insulin levels? I was listening to a podcast with Fung/Ramos, and one of them claimed "we all now know" that even though stevia doesn't increase glucose, it does raise insulin. But when I look for studies showing this one way or another, I get a lot claims that stevia is great for controlling glucose, and nothing scientific on the effects on insulin levels. So if we all know it, why am I having a hard time finding the science behind it?
