Free sugar vs total sugar

Where the sugar comes from: Leon LOVe Burger with Gluten-Free Bun

Portion	Total sugar	Free (added) sugar	Naturally occurring	Free sugar in teaspoons
Per portion	7.5g	6g	1.5g	1.5 tsp

Boone estimates that 6g of the 7.5g total sugar is free sugar, from the syrups and added sugar in the ingredient list. The remaining 1.5g is naturally present in 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.

Leon LOVe Burger with Gluten-Free Bun is made with a published list of at least 59 distinct ingredients. Reading it closely, it contains flavourings, flavour enhancers, colours, thickeners, gums and gelling agents, humectants, protein isolates and concentrates and added fibres.

Flavour enhancers

Colours

Restore or standardise appearance after processing.

Thickeners, gums and gelling agents

Hold texture and stop sauces, fillings or dairy from separating.

Humectants

Hold moisture so baked goods stay soft for longer.

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.

Boone classifies Leon LOVe Burger with Gluten-Free Bun as NOVA group 4, ultra-processed, based on the published ingredient list.
