Why it scores 52

Gold Peak Zero Sugar Sweet Tea scores 52 out of 100 (Okay) under GoodSwap’s published rules. What moved the score most:

  1. Aspartame: Labels must warn people with phenylketonuria (PKU) because aspartame contains phenylalanine (US and EU). Regulatory
  2. Ultra-processed (NOVA 4): Classified NOVA 4: made with industrial ingredients and additives. Strong
  3. Acesulfame potassium (Ace-K): In the NutriNet-Santé cohort, acesulfame-K intake was associated with higher cancer risk; cause and effect is not established. Strong

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