Yoghurt: free sugar versus lactose, by pot

Every yoghurt broken down by pot, separating naturally occurring lactose from added sugar and comparing against NHS daily free sugar limits for children.

Yoghurt is the clearest case where the total sugar figure misleads. Plain yoghurt contains only lactose, which is not free sugar and does not count against the NHS daily limit. Flavoured yoghurts add sugar on top, and that portion does count.

Plain, Greek and high-protein

Natural and Greek-style yoghurts typically carry 4 to 6g of sugar per 100g, essentially all lactose. Their free sugar figure is effectively zero.

High-protein and skyr products are similar, with the protein concentrated by straining. They are among the lowest free sugar options in the chiller.

Flavoured and children's yoghurts

Fruit, corner and dessert-style pots add sugar directly, and a single pot can carry a third or more of a young child's daily free sugar allowance.

Children's multipack pots are small, which helps, but the larger single pots marketed at children are frequently eaten in one sitting regardless of the stated serving.
