  2. Potassium benzoate: Benzoates can form small amounts of benzene in drinks that also contain ascorbic acid (vitamin C), especially with heat or light. Strong
  3. Sucralose: In a 2022 randomized study, sucralose and saccharin altered the gut microbiome and impaired glucose responses in some people; a 2023 lab study raised questions about its by-product sucralose-6-acetate. Strong
