ADI (Acceptable Daily Intake)

The estimated amount of a food additive or contaminant that a person can consume daily over a lifetime without appreciable risk to health. Established by JECFA and adopted by national regulatory authorities including EFSA and FDA. Expressed in mg (or mcg) per kg of body weight per day (e.g. sucralose ADI: 15 mg/kg bw/day). An ADI of "not specified" — used for substances like xanthan gum — is the highest safety classification, indicating safety at levels required for functional effect with no numeric limit necessary. Contrast with NRV (nutrient reference value for vitamins/minerals) and UL (tolerable upper intake level for nutrients).
