A Working Checklist for Added Sugar
Added Sugar: what is worth doing, what is worth avoiding, and when to stop and see a doctor.
Sugars added to food during manufacture or cooking, plus those naturally present in honey, syrups and fruit juice. Free sugars contribute energy without nutrients and are the principal dietary cause of tooth decay, and UK intakes run at roughly double the recommendation.
Key takeaways
- UK recommendation, adults: no more than 30g of free sugars a day
- Children aged 7-10: no more than 24g a day
- Most useful single change: Read the first three ingredients, which are ordered by weight.
- Commonest mistake: Reading "no added sugar" as meaning low sugar; fruit concentrates still count.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
Do
- Read the first three ingredients, which are ordered by weight
- Treat drinks as the first target; they are the largest single source for many people
- Swap flavoured yoghurt for plain with your own fruit
- Use the per-100g column to compare products rather than per-portion
Do not
- Reading "no added sugar" as meaning low sugar; fruit concentrates still count
- Replacing sugar with large amounts of refined starch and assuming it is better
- Fruit juice as a free alternative to whole fruit
The numbers behind the list
Here are the figures the checklist is drawn from.
| Measure | Figure |
|---|---|
| UK recommendation, adults | no more than 30g of free sugars a day |
| Children aged 7-10 | no more than 24g a day |
| Children aged 4-6 | no more than 19g a day |
| A 330ml can of regular cola | around 35g |
| High sugar on a label | more than 22.5g per 100g |
| Fruit juice, counted as free sugar | limit to 150ml a day |
If you change one thing
Read the first three ingredients, which are ordered by weight. That one first, and the others when you get to them.

When to speak to a doctor
See a GP if you are unusually thirsty, passing much more urine than normal, or losing weight without trying, which together can indicate diabetes. People with diabetes on insulin should take carbohydrate advice from their own team.

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
