I'd warn people not to pay too much attention to the advice that the american diabetes association provides. The targets it recommends are well known to cause damage to the body (you should be avoiding anything above a BG of 140 at any time) and it's dietary recommendations are contrary to the advice I've ever received from anyone that has had good results maintaining diabetes. Just to pick up on the two points you mention, I would never consume fruit unless accompanied by exercise and a low-carb diet is recommended by any consultant or nutrionist that I've ever spoken to.
