Cut back on free sugars
Reducing free sugars and frequent sweet snacks helps protect teeth.
The number, drawn
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
- Remember that unsweetened fruit juice, honey and syrups all count as free sugars.
- Choose plain yogurt and add whole fruit.
- Keep sweets and dried fruit to mealtimes rather than frequent snacks.
- Compare similar products using labels and ingredient lists.
Do it
Pick the time you have. Anything beats nothing.
Start with the time you have
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.
A plan
Reduce sweetness at your pace
- Week 1: Reduce added sugar in one regular drink or breakfast.
- Week 2: Try a plain cereal or yogurt with whole fruit.
- Week 3: Keep sugary foods and dried fruit to meals and review the changes you want to maintain.
In real life
- 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.
Watch out for
- Common mistakeDo not treat honey or juice as exempt: both contribute free sugars.
- Common mistakeDo not mistake total sugars for free sugars: check ingredients, since milk and whole fruit contain natural sugars.
