Free sugar vs total sugar

Where the sugar comes from: Domino’s The Sizzler Double Decadence pizza

All 53g counts as free sugar. Domino’s does not separate naturally occurring sugar from added sugar, so Boone counts the full figure. Sugars from sauces, glazes, dough and added sugar are free sugars; any from whole vegetables or milk would not be, so this may slightly overstate it. That is 13.3 teaspoons.

NHS daily free sugar limits: 30g for adults and children 11+, 24g age 7 to 10, 19g age 4 to 6.
