Free sugar vs total sugar
Where the sugar comes from: Leon Chargrilled Chicken Burger with Gluten-Free Bun
| Portion | Total sugar | Free (added) sugar | Naturally occurring | Free sugar in teaspoons |
|---|
| Per portion | 7g | 5.5g | 1.5g | 1.4 tsp |
Boone estimates that 5.5g of the 7g total sugar is free sugar, from the 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.
