If you had told me 10 years ago food dyes could affect children's behavior I would’ve rolled my eyes at you… oh wait I did! The use of artificial dyes has increased an insane amount in the past 50 years. Why should we avoid them as much as possible?
For starters, Red 40, this man made chemical is derived from petroleum (it’s a crude oil product used in gasoline, diesel fuel, asphalt, and tar). Red 40 also contains p-Cresidine, which is “reasonably anticipated to be a human carcinogen”. These dyes can disrupt the immune system.
