Free sugar vs total sugar

Where the sugar comes from: Leon Korean Chicken and Egg Sando

PortionTotal sugarFree (added) sugarNaturally occurringFree sugar in teaspoons
Per portion6.7g5.5g1.2g1.4 tsp

Boone estimates that 5.5g of the 6.7g total sugar is free sugar, from the syrups, added sugar, fruit juice and sauces in the ingredient list. The remaining 1.2g 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.

Ultra-processed food: what is really in it

Processing and additives: Leon Korean Chicken and Egg Sando

Leon Korean Chicken and Egg Sando is made with a published list of at least 51 distinct ingredients. Reading it closely, it contains emulsifiers, colours, industrial sugars, protein isolates and concentrates and baking improvers. These are not there to add nutritional value. They make industrial production and distribution possible.

Emulsifiers

Keep fat and water mixed so the texture stays even and does not separate.

Colours

Restore or standardise appearance after processing.

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.

Baking improvers

Speed up industrial bread making and keep bread soft for longer.

Boone classifies Leon Korean Chicken and Egg Sando as NOVA group 4, ultra-processed, based on the published ingredient list. NOVA groups foods by how far they are from their whole-food form, not by how nutritious they are. A group 4 food is not automatically unhealthy, and a group 1 food is not automatically healthy.
