This has been years in the making, but the FDA has banned Red #3 food coloring, though the science behind the ban is IMHO a bit shaky.

It'll take several years for products that currently use red #3 (like Peeps) to reformulate their products.

I wonder how people will make Red Velvet Cake in the future? Will they go back to using beet juice, which was the original way it was colored?
