Thank you for the edit. The NutriScore’s goal is to compare similar products from different brands, it was never intended to compare different products. The idea is that consumers that are not well informed and don’t read the labels would rather grab the cereals with B instead of the cereals with C next to them. This puts pressure on the producers to change their formulas. There are definitely still loopholes for “healthy-washing” but the rules can be and have already been changed.
Edit: Added vitamins do NOT improve the NutriScore btw but your point stands for fiber.
This is straight up misinformation. 95 percent of all foods are in the same category. Only fats, drinks and cheese have slightly different rules. Please edit your comment to stop the spread of misinformation.
