Why it scores 51

Quest Chocolate Brownie Protein Bar scores 51 out of 100 (Okay) under GoodSwap’s published rules. What moved the score most:

  1. Ultra-processed (NOVA 4): Classified NOVA 4: made with industrial ingredients and additives. Strong
  2. Erythritol: A 2023 study linked higher blood erythritol to cardiovascular events and found it increased clotting activity; long-term safety studies are warranted. 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
