The U.S. Food and Drug Administration is considering banning brominated vegetable oil, a food additive that was recently deemed unlawful to use in California because of its potentially harmful effects on human health.

The FDA said Thursday it is considering reversing its approval of brominated vegetable oil, or BVO, in beverages following a recent study in rats that found the ingredient could cause damage to the thyroid.

BVO was first used as a food additive in the 1920s. Today, it is used in some sports drinks and sodas to keep citrus flavoring from separating and floating to the top. Major soda makers announced they were dropping BVO several years ago.
