I read a thread about the meaning of "of which sugars", but I still don't quite understand. Let me just ask a simple question. If a product has 32% carbohydrate, and 47% of which sugars.... what does this mean? Are the sugars an extra category of carbohydrate, or are they just a subset of the overall carbohydrates? If I had 32% carbohydrates and 47% of which sugars, would the total carbohydrates be 32% or would they be (32% + 47%) = 79%?
