5. Regular Soda
There is a lot wrong with soda – it has no redeeming health value at all. Like energy drinks, it contains a ton of sugar, caffeine, and artificial ingredients. One of those chemical additives is a colorant called 4-MeI. It gives cola its brown color, but is also a known carcinogen.
Regulations on the use of 4-Mel differ from place to place, but California at least requires that it be labeled as potentially cancer-causing on all food products that contain it.
