aspartame, makes no claims for health benefits, other than to be a virtually calorie free sugar substitute, especailly beneficial for people with diabetes. Its benefits in improving the diets and health of diabetics is proven, despite any of the side effects others may experience (and I happen to be one of those who can not use aspartame). It doesn't make claims to cure any illness, and yet it is subject to FDA approval as well. Proving the point that something that makes health claims had better be able to prove it.

They are consistent, and their role is an important one, even if it seems cumbersome at times
