Interesting - I saw this article and thought it'd be talking about red #40, which has been linked to ADHD-like symptoms in children [1]. I've been pleased to see more food items replacing artificial colorings with things like beet juice lately.
Beet juice, annatto, spirulina, carrot juice / beta carotene, and many other options abound. What infuriates me is when I see something white (like vanilla pudding) that contains blue #5... for no good reason.
