 The FDA has banned a soda additive over health concerns. The additive called BVO is a vegetable oil that stops citrus from separating and floating to the top of your drink. It was found to be a huge health concern and has a particularly nasty effect on your thyroid. The ban goes into effect next month, but don't panic just yet. Most major brands have pretty much already eliminated the ingredient from their product lines. BVO is still being used in lesser-known sodas that are currently on store shelves.
