High fructose corn syrup (HFCS) is a type of sugar made from corn. It is often used as a sweetener in processed foods and drinks. HFCS is cheaper and sweeter than table sugar, so it is used widely in the food industry.
Your body can break down HFCS, but it takes longer than other types of sugar. This means that HFCS can stay in your blood for longer and raise your blood sugar levels more than other sugars.
HFCS has been linked to obesity and other health problems, so it is important to limit your intake of foods and drinks that contain this type of sugar.
