The FDA's goal is to make nutrition labels as useful and understandable as possible, while keeping the information in line with current dietary guidelines. For example, in the past decade or so it has become clear that “total fat” is not a very useful number since some fats are actually good for you while others are definitely not good. Future label changes are likely to emphasize the content of “bad” fats such as saturated fats, trans fats, and cholesterol. And in terms of weight management, total calories need special emphasis.
It’s all part of the plan to keep nutrition labels “fresh” and meaningful.
