Fructose is found naturally in many foods, such as fruits, vegetables, and honey. It is also a component of sucrose, or table sugar, which is extracted from sugar cane or sugar beets. In recent decades, high-fructose corn syrup has become a prevalent ingredient in processed foods and beverages due to its sweetness and low cost. This HFCS typically contains 55% fructose and 45% glucose, making it similar to sucrose in its fructose content.
