Nutritional content

One orange provides about 10 g of carbohydrate in the form of natural sugar. Oranges also contain some fibre and they have a high vitamin C content. All oranges are a good source of folate and carotene (vitamin A) with particularly high levels of carotene found in red blood oranges. Useful amounts of calcium and magnesium are present in both oranges and orange juice. Although oranges have a low iron content, the high vitamin C level helps the absorption of iron from other non-meat foods, especially eggs.
