The most important thing to realise is that carbs turn to glucose when digested, the colour of the carbs makes no difference. Wholemeal bread, brown rice may take a little longer to digest but the glucose will eventually get into your blood.
Hopefully as you are not yet a full blown T2, cutting back on the main culprits could be all you need to get back to normal levels.
Bread, rice, pasta, obvious thing like pastries and biscuits, and beware of the things mainly considered healthy like oats, cereals and fruit, they contain far too many carbs to be healthy fou us.
