Recently I met an Indian homoeopathy doctor who organizes workshops on diabetic awareness. He is more interested in treating people with just food rather than homoeopathic medicines.
He advices to replace rice and wheat (mostly all sorts of sugars) with five types of millets which can bring down Hba1c to greater extent (~6). I was surprised to see few reports showing the results.
In Bangalore (Karnataka-India) Millets foods are becoming popular these days.
