As long as you count your carbs, you should be OK. You will also find that your blood sugar is likely to be more sensitive to certain types of foods regardless of their carb count (e.g., I have trouble eating pears anymore--they spike my blood sugar). Some good high bang for the buck snacks include: watermelon (believe it or not, because of the water content you can eat more watermelon than other kinds of fruit in terms of the volume), cheese sticks/cheese wedges, nuts (peanuts, pistachios, almonds are particularly good), fresh oranges. You also need to consider the fat content of what you are eating. In general, if the carbs are combined with fat and if the carbs are combined with significant amounts of fiber, the effect of the carbs on your body will be lower. For example, if you have to eat candy, carb for carb chocolate will be a better bet than most because of the fat content. In moderation, chocolate does not spike my blood sugar (and that is why if you have low blood sugar they tell you not to try to raise it with chocolate).
Hope this helps.
