Why it scores 60

Pure Protein Strawberry Milkshake scores 60 out of 100 (Good) under GoodSwap’s published rules. What moved the score most:

  1. Sugar: An added sugar. Strong
  2. Red 3: The FDA revoked its authorization for food in January 2025 under the Delaney Clause because high doses produced tumors in male rats; the FDA says there is no evidence of this effect in humans. Regulatory
  3. Cellulose gum (carboxymethylcellulose): In a small randomized feeding trial, carboxymethylcellulose modestly increased abdominal discomfort and reduced gut microbiota diversity; in mice it promoted low-grade inflammation. Strong

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

  • Potassium phosphate
    Strong EFSA (2019) set a group ADI for phosphates of 40 mg/kg body weight (as phosphorus) and noted that infants, toddlers and children may exceed it. [20]
