I have never had insulinissues but a lot of people around here and all over the paleo community swear by eliminating the main dietary cause of diabetes, being carbs and especially fructose. There is more to developing it than just carbs, but the one thing that most agree upon is the importance pf eliminating the large, prolonged glucose-spikes that cause so much damaging to the body.

I think reducing fructose is just as, if not more, important than starch, but it's clear that both are bad guys.
