  1. Ultra-processed (NOVA 4): Classified NOVA 4: made with industrial ingredients and additives. Strong
  2. 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
  3. 6 kinds of ultra-processing markers: Industrial additive classes found: emulsifier, flavoring, humectant, industrial protein, non-nutritive sweetener and sugar alcohol (polyol). Emerging

  • Collagen
    Info An ingredient typical of ultra-processed foods (NOVA group 4). [6]
  • Maltitol
    Regulatory Large amounts can have a laxative effect; the EU requires a label statement above 10% added polyols and the US for some polyols above set intakes. [7][8]
  • Caseinate
    Info An ingredient typical of ultra-processed foods (NOVA group 4). [6]
  • Glycerin
    Info An additive class typical of ultra-processed foods (NOVA group 4). [6]

    Strong About half saturated fat; WHO recommends keeping saturated fat to 10% of energy or less. [9][10][11]
  • Whey protein concentrate / isolate
    Info An ingredient typical of ultra-processed foods (NOVA group 4). [6]
  • Natural flavors
    Info "Natural flavor" is a legal category (21 CFR 101.22(a)(3)): flavor substances from spices, fruits, vegetables, meat, dairy or fermentation. [12][6]
