Why it scores 29

Dr Pepper Zero Sugar scores 29 out of 100 (Poor) under GoodSwap’s published rules. What moved the score most:

  1. Caramel color: The FDA says classes III and IV, which can contain 4-MEI, are the most commonly used food color additives by volume. Regulatory
  2. Aspartame: Labels must warn people with phenylketonuria (PKU) because aspartame contains phenylalanine (US and EU). Regulatory
  3. Ultra-processed (NOVA 4): Classified NOVA 4: made with industrial ingredients and additives. Strong

Every line of the math is on The Receipt below, with its evidence tier and sources.
