Sugar-free vs no added sugar

Two regulated claims that sound identical and are not — one is about total sugars, the other about what was put in.

Why these get confused

They are used as though they were the same claim and they are regulated separately. The gap opens where milk solids are present, because lactose is a sugar that occurs naturally in the ingredient rather than being added — so a no-added-sugar milk chocolate can contain a meaningful quantity of sugar.

Side by side

 Sugar-freeNo added sugarWhy it matters
What the claim meansTotal sugars are below a defined threshold. In the EU this is a regulated nutrition claim with a specified figure.No sugars were added as an ingredient. Naturally occurring sugars in the other ingredients are permitted.Sugar-free constrains the finished product. No added sugar constrains the recipe, and the two can diverge.
Where the divergence bitesConsistent across compositions, because it is measured on the finished product.Milk chocolate. Milk powder brings lactose, so a no-added-sugar milk bar contains sugar it did not add.Reading a no-added-sugar milk chocolate as sugar-free is the specific error this pair produces.
What replaces the sugarUsually a polyol — maltitol, erythritol, xylitol — sometimes with a high-intensity sweetener alongside.Frequently nothing at all. The product is simply less sweet, or the sweetness comes from an ingredient's own sugars.Polyols carry digestive effects at quantity, which is why sugar-free confectionery frequently carries a laxative-effect statement. A no-added-sugar product may carry none.
Energy contentNot reduced by the claim. Fat is the dominant energy source and is unchanged.The same.Neither claim is a claim about calories, and both are routinely read as one.

Choose Sugar-free when

When total sugar is the thing being minimised and a sweet product is still wanted. Read the polyol used and its quantity.

Choose No added sugar when

When the concern is added sugar specifically rather than total sugars, or when you want to avoid polyols.

When the distinction does not matter

High-percentage dark chocolate reaches a low sugar load without either claim and without substitution. A 90 per cent bar is an ordinary product that answers the underlying question directly.
