Fine in a portion — worth keeping an eye on.
A cup of blueberries lands around 15 g of sugar. That's more than strawberries, but blueberries bring nearly 4 g of fibre and one of the densest antioxidant profiles in the produce aisle, so they earn their place.
For a lower hit, half a cup does most of the flavour work for half the sugar — great stirred through plain yogurt or oatmeal instead of a sugary flavoured version.
Lower-sugar swaps
- Use half a cup to sweeten plain oatmeal instead of sugar or honey
- Mix with strawberries to lower the average sugar per bowl
