Ingredients

  • Sugar
    Strong An added sugar. [1][2][3]
  • Dextrose
    Strong An added sugar. [1][2][3]
  • Cellulose gum (carboxymethylcellulose)
    Strong In a small randomized feeding trial, carboxymethylcellulose modestly increased abdominal discomfort and reduced gut microbiota diversity; in mice it promoted low-grade inflammation. [4][5][6][7]
  • Sucralose
    Strong 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. [8][9][10][11][2]

Processing

  • Ultra-processed (NOVA 4)
    Strong Classified NOVA 4: made with industrial ingredients and additives. [12]
  • 4 kinds of ultra-processing markers
    Emerging Industrial additive classes found: flavoring, industrial sugar or starch hydrolysate, non-nutritive sweetener and thickener, stabilizer or gelling agent. [12]
