Titanium DioxideColorant
Banned in the EU (2022) over concerns that its ultra-fine particles may damage DNA in gut cells. Still allowed in the US. Used only for white coloring — provides no health benefit.
CarmineColorant
Insect-derived (not vegan/vegetarian) and a recognized cause of IgE-mediated allergic reactions, including documented anaphylaxis. The FDA mandated explicit 'carmine'/'cochineal extract' labeling in 2011 specifically because of these reactions. Not toxic to the general population, but a genuine allergen with no health benefit; plant pigments achieve the same color.
