I think the question is how many carbs are you supposed to be eating? 70g per day? 30g per day?
Whatever it is it will need to be made up from the total carbs figure on any nutritional information. The thing to watch out for is that carb split on the packet. Generally high sugars will cause your blood sugar to spike rapidly post eating, where lower sugar and higher complex carbs will take longer for the BS increase.
The other thing about high sugars in a meal is that you will not remain satiated for that long after eating and will quickly be hungry again.
Best to avoid anything with a high total carb content if you are a type 2 trying to lower blood glucose by diet.
