How can you be sure that your Danone Go yogurt contains 30% less sugar?

Our Danone Go drinkable yogurt contains 30% less sugar for the same volume as the leading 200mL drinkable yogurt. The leading 200mL drinkable yogurt contains 18g of sugar per 200mL compared to 12g of sugar per 190mL for the Danone Go (or 12.6g per 200mL). Regular checks are done to guarantee this sugar level.
