A lot of people on this thread revealing they can't read "in context" and are upset if every term used doesn't have a footnote.

I guess all the people complaining would prefer lawyer speak:

"FD&C¹ dyes (hearinafter known as DYES)"

¹ FD&C the U.S.² act governing (and defining) the regulation of food, drugs and cosmetics. This act is enforced by the FDA.

² The United States Of America

Addendum: This article is about how the FD&C (as an Act) defines a dye vs a lake.
