4. Mountain Dew
Long the favorite of caffeine junkies everywhere, Mountain Dew is so chemical laden that you wouldn’t want to drink the dew off of any mountain it came from. That powerful citrus flavor is created with a chemical called brominated vegetable oil or BVO.
And by the way, BVO is also used as a flame retardant. Besides Mountain Dew, it shows up in the sodas Squirt, Fanta Orange, Sunkist Pineapple, Gatorade Thirst Quencher Orange, Powerade Strawberry Lemonade, and Fresca Original Citrus.
BVO has been banned in foods from Europe and Japan, but not the good old USA. Overexposure to BVO had led some people to need medical attention for skin lesions, memory loss, and nerve disorders. Get your caffeine some other way.
