BHTPreservative
Potential carcinogen in animal studies; may affect thyroid function; restricted in some countries
FD&C Red No. 40 LakeColorant
Same petroleum-derived azo dye as Red 40, linked to hyperactivity in children (Southampton study) and carrying an EU warning label; pure cosmetic color with zero benefit.
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.

May trigger sensitivity in some individuals; behavioral concerns in susceptible children
