Comment: Additives in the foods we eat

I was going through this with a friend in the US about a year or so ago because of her son, Half of what is in our foods is banned over there. I really can't remember all the details but I did pull up the american web site with the list of all their food additives, numbers, and I am sure that I also stumbled onto a US website that listed all the dodgy ones to and the possible side effects.
Cheers
