Free sugar vs total sugar

Where the sugar comes from: Leon Aji Verde Crispy Chicken Burger with Gluten-Free Bun

PortionTotal sugarFree (added) sugarNaturally occurringFree sugar in teaspoons
Per portion8.6g6g2.6g1.5 tsp

Boone estimates that 6g of the 8.6g total sugar is free sugar, from the syrups, added sugar and fruit juice in the ingredient list. The remaining 2.6g is naturally present in milk and dairy, vegetables and pulses and grains. LEON publishes total sugar only, so this split is Boone's estimate.

NHS daily free sugar limits: 30g for adults and children 11+, 24g age 7 to 10, 19g age 4 to 6. Sugars naturally present in milk and whole fruit are excluded. Sugars in fruit juice, purées, syrups and plant drinks made from hydrolysed grains count as free sugar.

Industrial sugars

Refined sugars made from starch, used for sweetness, browning or bulk.

Protein isolates and concentrates

Proteins extracted from plants to add bulk, bind or replace egg and meat.

Added fibres

Isolated fibres added for texture, bulk or a fibre claim.
