Reducing free sugars and frequent sweet snacks helps protect teeth.

**The number:** No more than 30 g of free sugars daily for adults ([NHS, 2023](https://www.nhs.uk/live-well/eat-well/food-types/how-does-sugar-in-our-diet-affect-our-health/))

## The evidence

- Evidence grade: A. Grade A: meta-analyses of randomised trials, or a major guideline consensus.
- Basis: National free sugar guidance and evidence on dental decay
- Outcome: adult free sugar intake, no more than this amount
- Comparison: NHS adult upper limit, not total sugars
- Impact: 63/100. The impact score is an editorial prioritization heuristic for the general list, not a validated estimate of your personal risk.

## Why it matters

Free sugars include added sugar, honey, syrups and the sugars released into juice. They feed the processes that cause tooth decay, especially with frequent exposure. The NHS adult guideline is no more than 30 g daily, distinct from the sugars naturally present in intact fruit and milk.

## How to do it

1. Remember that unsweetened fruit juice, honey and syrups all count as free sugars.
2. Choose plain yogurt and add whole fruit.
3. Keep sweets and dried fruit to mealtimes rather than frequent snacks.
4. Compare similar products using labels and ingredient lists.

## Putting it into practice

### Start now

- 1 minute: Name your usual sweet topping or added sugar, then choose one change: less sugar in tea, or whole fruit instead of honey.
- 5 minutes: Compare two similar cereals or yogurts using total sugar per 100 g and the ingredient lists; choose a suitable option with less added sugar.
- 15 minutes: Prepare a breakfast of plain yogurt or porridge with whole fruit, using foods you tolerate and no added syrup or honey.
- 30 minutes: Review a typical day's drinks, breakfast, snacks and desserts; choose two free sugar sources to reduce without cutting out whole fruit or plain milk.

### What it looks like

- Top plain yogurt with chopped whole fruit instead of honey.
- Use a little less sugar in your usual tea, then reduce again when ready.
- Have dried fruit with breakfast instead of grazing on it between meals.

### Common mistakes

- Do not treat honey or juice as exempt: both contribute free sugars.
- Do not mistake total sugars for free sugars: check ingredients, since milk and whole fruit contain natural sugars.

### A structured start

**Reduce sweetness at your pace**

1. Week 1: Reduce added sugar in one regular drink or breakfast.
2. Week 2: Try a plain cereal or yogurt with whole fruit.
3. Week 3: Keep sugary foods and dried fruit to meals and review the changes you want to maintain.
