“In Europe, Allura Red AC is not recommended for consumption by children. It is banned in Denmark, Belgium, France and Switzerland, and was also banned in Sweden until the country joined the European Union in 1994. The European Union approves Allura Red AC as a food colorant, but EU countries’ local laws banning food colorants are preserved.”
Add to that Yellow#5 and Yellow#6.
All three of these artifical colorings have been implicated in:
McCann D, Barrett A, Cooper A, et al. (November 2007). “Food additives and hyperactive behaviour in 3-year-old and 8/9-year-old children in the community: a randomised, double-blinded, placebo-controlled trial”. Lancet 370 (9598): 1560–7. doi:10.1016/S0140-6736(07)61306-3. PMID 17825405.
Food coloring, or color additive
My take on this is that, like with lots of different things, some people are fine with it, some people are not so fine, and some are really bad and must avoid completely. For example… here’s a quote I read:
“We cannot do Red 40 at all in our house. When our four year old has even the smallest amount it leads to diarrhea, mood swings, hyper activity, stuttering, night terrors, and it is a trigger for her absence seizures. When our two year old has even the smallest amount it leads to hyper activity, and full body hives. We have had to eliminate it entirely from our home and that includes things like medicine, toothpaste, and lip gloss even. I will never forget when our two year old licked some pink girlie lip gloss and got a rash on her face that made her look like the joker.”
