Fructose is harmful, unfortunately. Sucrose gets split by the body into one fructose and one glucose molecule. And it is the fructose that is harmful because it cannot be properly processed by the liver in large quantities. Sucrose is only harmful in as much as it produces fructose. It is true that fructose appears naturally all over the place. And that is the tricky part. The liver can actually process fructose fine if it gets a little at a time and simultaneously receives fiber. Almost everywhere fructose occurs naturally it occurs with fiber. Thus, the human body is perfectly capable of processing fructose in its natural state, but once you start concentrating it and removing the fiber the problems come about. This is why fruits and veggies are perfectly healthy but refined sugars are bad for you.
