It appears that Vegan input beats anti-Diabetes standards, at least in the USA.
Vegan is pretty straightforward to do, too: reject anything animal (milk, eggs, and of course anything like meat or animal fat) and get it as close to raw as possible. Mountains of strawberries, mangoes and so on — ooh! sentence me! faster! — which it seems reduces all manner of odd symptoms from additives acting like weird diseases [sorry, I dropped that link].
