As far as your blood sugar is concerned,
carbs are
carbs, whether they come from corn or candy, bread or ice cream, pasta or potato chips. Type-1 diabetics "count" the amount of carbs in a meal or snack and give themselves the appropriate amount of insulin so their bodies can process those carbs. If my daughter wants a snack and doesn't want to give herself a shot, she has some protein or veggies-- a piece of chicken, or some carrots, because their carb count is so low.
