Where is fructose commonly found?

Fructose is commonly found in fruit, which is why this choice is the correct answer. It is a natural simple sugar (monosaccharide) that is present in many fruits, contributing to their sweetness and providing energy. Fruits such as apples, pears, and berries are particularly high in fructose, making them not only a healthy snack but also a significant source of this sugar.

While fructose can also be found in other food sources, such as some root vegetables, grains, and even in milk in the form of lactose, these are less commonly recognized for their fructose content compared to fruits. The high concentration of fructose in fruits, particularly when eaten fresh, is a key reason why they are often highlighted in discussions about sugars and nutrition. Fruits provide essential vitamins, minerals, and dietary fiber in addition to their natural sugars, emphasizing their role in a balanced diet.
