Fructose is a simple sugar found in many foods. Common table sugar is made of equal amounts fructose and glucose. Similarly, high-fructose corn syrup, commonly used to sweeten foods, contains a mixture of fructose and glucose. Fructose is sweeter than glucose, and for this reason it has been used in many sweetened foods.
