How about adding some petroleum into your food? Or into your child’s food? Well, that sounds absolutely gross and an unimaginable thing to do. But that is exactly what you do when you eat processed food loaded with artificial food dyes in addition to preservatives and flavour enhancers. Yes, you read correctly! Most synthetic food colours that are added to processed foods come from coal-tar and petroleum. Look around and you will find these food dyes everywhere from your flavoured yogurts to fruit juices and breakfast cereals and even some supplements.
