White sugar is effectively the same as HFCS. Sugar is 50/50 glucose/fructose. HFCS has a bit more, depending on the type, but the fact that fructose is bound into a sugar molecule makes little/no difference as we have an enzyme (sucrase) that splits it immediately.

At the top of my 'very worst' list is sugar or HFCS sweetened beverages, then fruit juice. Consuming fructose in liquid form means a sudden onslaught of fructose at the liver. And cold beverages get to the small intestines faster than room temp or warm/hot.

Then come all the 'natural' sweeteners ( honey, maple syrup, agave syrup, etc).

Then dried fruits.

At the very bottom come fruits eaten whole/uncooked. Yes, they have fructose, but not much, and the combined kinds of fiber that they also contain mean slow/gradual absorption - and some even passes to the large intestine where your microbiome can make SCFAs (which are good) for you.
