Oranges are among the world's most popular fruits.
Also called sweet oranges, they grow on orange trees (Citrus x sinensis) and belong to a large group of fruits known as citrus fruits.
Their true origin is a mystery, but the cultivation of oranges is thought to have started in eastern Asia thousands of years ago.
Today, they are grown in most warm regions of the world and consumed either fresh or as juice.
Oranges are a healthy source of fiber, vitamin C, thiamine, folate, and antioxidants. They have multiple health benefits.
Oranges are mainly composed of carbs and water, with very little protein and fat and few calories.
Simple sugars - such as glucose, fructose, and sucrose - are the dominant form of carbs in oranges. They are responsible for the fruit's sweet taste.
Despite their sugar content, oranges have a low glycemic index (GI) of 31–51 (1).
This is a measure of how quickly sugar enters your bloodstream after a meal.
Low GI values are associated with numerous health benefits (2).
Oranges' low GI is explained by their high polyphenol and fiber content, which moderates the rise in blood sugar (3).
