Chronic exposure to synthetic food colorant Red 40 promotes colitis in mice

Seems like we should ban food coloring or make the increasingly less useful "organic" label include a ban on food colorings.

"Here, we show chronic exposure of AR at a dose found in commonly consumed dietary products exacerbates experimental models of colitis in mice. While intermittent exposure is more akin to a typical human exposure, intermittent exposure to AR in mice for 12 weeks, does not influence susceptibility to colitis."

The article plainly states that the exposure that's common to humans produced no results in mice.

How about no food coloring? Don't you want to see the actual color of your food, or would you let a factory disguise it? Or let's use natural coloring. It seems like the risk benefit ratio is high for consumers, but mundane considering the increase in revenues.

I have taken prescription pills that have so much dark blue coloring in the coating, it motivated me to call the pharmacy and ask for a different generic brand where the pills are white.

I get that drug manufacturers are trying to distinguish different meds, but putting this much coloring in pill coatings seems like a really bad idea. If long-term use of the medicine doesn't cause problems because of side effects, the deep color in the pill coating might!

I thought that Red 40 was banned in Canada as we tend to see things coloured using alternate dyes, but I'm unable to confirm this and I'm starting to wonder if it isn't actually banned.

EDIT: I did learn today that the "FD&C" label on colours are those colours that have transitioned from being a straight "chemical" mixture to a validated and analyzed pure sample of a potential batch of colour.

Oh, a cousin of Azorubin (E122).

Azorubin cleens the spleen!
