I'm afraid that the natural alternative to too high levels of glucose in the bloodstream is to eat fewer carbs, as our problem, as type two diabetics, is the inability to deal with carbohydrate.
To get normal numbers I need to eat under 40 gm of carbs a day. Few need to go as low as that, but I avoid high carb foods and eat salads, stir fries, stews - foods with a low percentage of carbohydrate, and it works very well.
