I've almost always known that they use coloring in drinks like pepsi and coca cola, but I've never given it that much thought. Luckily I've never liked the taste of either of them. What is discouraging is that very few people read the label, and even the label can be misleading, like with that caramel color. And even if you read the label, google the ingredients and read some researches, you can still feel confused. It's just much better to eat natural foods, so you don't have to ponder whether the foods you're consuming will be carcinogenic or not.

Again, well done @dandays! Really informative post with a lot of effort put into it!
