Concern level

Low concern Level 1 of 4 How concern levels work

A minor or very limited concern, such as being an ultra-processing marker only. The concern level sets how many points potassium phosphate costs on a product’s receipt.

What the evidence says

  • Low concernStrong evidence

    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. [1]

Evidence tiers say how sure the evidence is, separately from how much it matters. About evidence tiers.
