If you live in America and eat or serve your kids "snacks" it is most likely you are being subjected to artificial food dyes. If you are drinking enhanced or flavored water, it is likely you are being subjected to artificial food dyes. If you are eating soft serve ice cream or going to fast food restaurants...well dyes are in many of those foods too.
What are artificial food dyes? Red 40, Yellow 5, Yellow 6, and Blue 1 are the top 4 in the US. These are additives the FDA does not restrict from our nations food supply. Those pretty colors that make the "fruit punch" red, the gelatin green and the oatmeal blue are made from petroleum (crude oil) which is also the source for gasoline.
