“European countries take a much more precautionary approach to additives in their food, Benesh says. “If there are doubts about whether a chemical is safe or if there’s no data to back up safety, the EU is much more likely to put a restriction on that chemical or just not allow it into the food supply at all.”
In the US, we’re more likely to see action at the state level. California banned four chemicals in 2023: brominated vegetable oil, Red Dye No. 3, propylparaben, and potassium bromate. This year, lawmakers in about a dozen states have introduced legislation banning those same chemicals and, in some states, additional chemicals as well. But federal oversight has been limited, constrained by priorities, authority, and by a lack of resources.”
