Net carbohydrate values are determined by subtracting the number of sugar grams and fiber grams from the total grams of carbohydrates in a food item.
Here is the catch: When it comes to food labeling, in countries like US and Canada,
carbohydrate values also include fiber (i.e. total carbs).
I would test my blood glucose, work out
the carbohydrate value of my meal, inject my insulin accordingly and eat my dinner.
