Fine in a portion — worth keeping an eye on.
A whole medium orange has about 12 g of sugar, balanced by roughly 3 g of fibre and more than a day's vitamin C. Eaten in segments it's filling and slow to digest.
The story flips with juice. It takes 3–4 oranges to make one glass, so orange juice concentrates the sugar and loses the fibre — a glass can hit 21 g in seconds.
Lower-sugar swaps
- Eat the whole fruit instead of drinking juice
- Add orange segments to water for flavour without the sugar load
Frequently asked questions
- Is a whole orange better than orange juice?
- Much better. The whole fruit keeps its fibre and fills you up; juice strips the fibre and concentrates the sugar of several oranges into one glass.
