HFCS is generally in the range of 50% to 90% fructose. In other words, it's typically worse than sucrose for you. Fructose does not provoke a satiety response in the human gastroenteric system, unlike glucose. So if you do eat candy, prefer sucrose to HFCS and glucose to sucrose. Sucrose will be listed on packaging as "sugar".
