Flagged additives

• Sodium benzoate — Preservative; can form trace benzene (a carcinogen) when combined with ascorbic acid; implicated in child hyperactivity studies.
• Monosodium glutamate (MSG) — Flavour enhancer; self-reported intolerance ('MSG symptom complex'); EFSA flagged exposure above the group ADI.
• Sucralose — Sweetener; emerging genotoxicity concern around the impurity/metabolite sucralose-6-acetate.
• Annatto / bixin / norbixin — Natural colour; occasional allergic/intolerance reactions.
• Triphosphates — Inorganic phosphate additives are highly bioavailable; high additive-phosphate intake is associated with increased cardiovascular and kidney burden, particularly in chronic kidney disease.
• Polyphosphates — Inorganic phosphate additives are highly bioavailable; high additive-phosphate intake is associated with increased cardiovascular and kidney burden, particularly in chronic kidney disease.
• Disodium 5'-ribonucleotides — Ribonucleotide flavour enhancer typically used together with monosodium glutamate (E621); may contribute to symptoms reported by glutamate-sensitive individuals.
