Sucralose

A sweetener in diet drinks and sugar-free foods.

In the body: The limit comes from a rat study in which the highest doses slowed weight gain, with a safety margin on top.

Not rated by dose: a flag on 2 reviewed foods, among them Whey protein concentrate and Diet cola.

Builds up over time. Agencies set an amount you can take in every week, or every day, for life. A food measured against it shows the grams that reach it.

Grams to the limit

No reviewed food here has a measured level yet, so none has a gram figure. The limit is shown, ready for the first measurement; each line below says what the food is flagged for.

  1. Diet cola

    Not rated yet for a 375 g serving

    No gram figure for this food
    We have no measurement of this in this food, so there is no gram figure.

    EFSA 2026 · grade B

    How it’s rated

    Not rated: the label says some diet colas on the Canadian market contain sucralose but gives no amount, and a label is not a measurement. EFSA's 2026 re-evaluation kept the acceptable daily intake of 15 mg/kg body weight/day, 1,050 mg a day for 70 kg. EFSA's mean exposure runs from 0.1 mg/kg body weight/day to 4.7 in toddlers; at the 95th percentile, from 0.4 to 14.3 in toddlers.

    Intake: one 375 mL reference amount (375.4 g at 1.00101 g/mL) a day, 70 kg adult

    Measured on: Castellanos 2025 could not quantify sucralose (no chromophore; 'neither sucralose nor cyclamate were included in the statistical analyses'); Knezovic 2025 (Croatia) measured four other sweeteners; no measured sucralose content in a diet cola was found within the budget

  2. Whey protein concentrate

    Not rated yet for a 30 g serving

    No gram figure for this food
    We have no measurement of this in this food, so there is no gram figure.

    EFSA 2026

    How it’s rated

    Not rated: EFSA's acceptable daily intake stays at 15 mg/kg body weight/day (1,050 mg a day for 70 kg), but no sucralose level in any whey powder was found, so no grams figure. Only flavoured ones carry it; 12 of 14 whey powders in a Hungarian sample declared it.

    Intake: not applicable (flag)

    Measured on: flavoured whey powders sweetened with it (either variant); no concentration in any whey powder found or measured; labels not read
