High-fructose corn syrup (HFCS) is a sweetener made from corn starch. It is produced by converting some of the glucose in corn syrup into fructose, resulting in a syrup that is sweeter than regular corn syrup. HFCS is commonly used in many processed foods and beverages, including soft drinks, candies, and baked goods, due to its low cost and ability to enhance flavor. HFCS is often compared to sucrose, or table sugar, as both are used to sweeten foods. However, some studies suggest that excessive consumption of HFCS may be linked to health issues, such as obesity and diabetes, prompting ongoing debates about its impact on diet and health.
