Fructose is a simple sugar found naturally in many fruits, honey, and root vegetables. It is one of the main components of sucrose, which is table sugar, and is often referred to as "fruit sugar." When consumed, fructose is quickly absorbed by the body and can provide a quick source of energy. While fructose is a natural part of a healthy diet, excessive consumption, especially from processed foods and sugary drinks, can lead to health issues like obesity and diabetes. It's important to enjoy fructose in moderation, primarily through whole fruits, which also provide essential vitamins and fiber.
