In my personal experience (my dad was diabetic, and mom is too), type 2 diabetes responds well to stevia consumption, but natural, unprocessed stevia. In addition to sweetening foods and reducing cravings for sweets, it also has the ability to control blood glucose levels.

I understand, although I haven't read the scientific studies, that stevia (natural, unprocessed) helps regenerate pancreatic cells.

And yes, diabetics tend to ingest higher than average amounts of sugar because, as a result of the deterioration of the nervous system, they lose their sensitivity to flavors. That's why they like extremely sweet, salty, or acidic foods.
