Coca Cola is......well quite frankly a bit worrying

Coke and Pepsi alter recipe to avoid cancer warning label

Coca-Cola and Pepsi are changing the recipes for their drinks to avoid putting a cancer warning label on the bottle, to comply with California laws. The new recipe for the drinks' caramel colouring will have less 4-methylimidazole, a chemical California has added to its list of carcinogens. The change to the recipe has already been introduced in California.
