An orange is mostly water (about 87%) and provides 47 kcal (197 kJ) per 100 g, nearly all from natural sugars. The fruit is best known for vitamin C, with 53 mg per 100 g, and it also brings a useful amount of fibre and folate. Fat and protein are negligible, so its energy is almost entirely carbohydrate, slowed down somewhat by the fibre in the segments and pith.

Things worth knowing

• One medium orange (131 g) has about 62 kcal / 258 kJ and around 70 mg of vitamin C, which is close to 77% of the 90 mg Daily Value.
• Orange juice has a similar energy density (45 kcal per 100 g) but only 0.2 g of fibre per 100 g against 2.4 g in the whole fruit, and a glass is easy to drink in seconds.
• A large orange (184 g) is about 86 kcal / 362 kJ, and a small one (96 g) is about 45 kcal / 189 kJ, so size changes the count more than variety does.
• The white pith is edible and holds part of the fibre, so peeling less thoroughly keeps more of it.
