An easy fit for a low-sugar day.
A slice of white bread has just 1.4 g of sugar, so on the label it looks innocent. The nuance is that refined white flour is rapidly broken down into glucose, so it affects blood sugar much like sugar itself — even though little 'sugar' is listed.
This is why cutting sugar often means looking at refined carbs too. Wholegrain or seeded bread has more fibre, digests slower, and keeps you fuller — a better everyday choice than the sugar figure alone suggests.

Frequently asked questions
- If white bread is low in sugar, why does it affect blood sugar?
- Refined flour is digested quickly into glucose, so it raises blood sugar fast despite showing little 'sugar' on the label. Wholegrain bread digests more slowly.
