The Food and Drug Administration on Thursday proposed banning the use of brominated vegetable oil, a food ingredient once widely used in popular drinks like Gatorade and Mountain Dew that has been slowly phased out due to its link to potential health risks, including damage to the liver, heart and brain.
Brominated vegetable oil is a food additive primarily used in fruit-flavored sports drinks and sodas to keep ingredients from separating. It contains bromine, an element found in flame retardants.
Although many large beverage brands, including Coca-Cola and Pepsi, have already stopped using the ingredient in their products, it can still be found in smaller grocery store brands and some popular regional beverages, like Sun Drop citrus-flavored soda.
The European Union and Japan ban the use of the ingredient in food and drinks.

Previous studies have also shown that it could potentially be harmful to the liver, heart and cause neurological problems.
