One other thing, OP, string cheese is not a free food. It is a dairy, which means it counts as a carbohydrate. Carbs are the items that must be watched by diabetics. Dill pickles are free foods as are most vegetables with the exception of corn, beans and peas. Bread, rice, pastas, crackers, dairy and fruits are all carbohydrates. That's why he needs the fruit juice when his BG goes low. Carbs are a quick lift to BGs, but too many carbs and you end up with a high.
