1. IMO, HFCS (High Fructose Corn Syrup, a synthetic product - about 3 types) may is poisonous to our livers as you stated. According to studies, it must be almost entirely metabolized by the liver.

The fructose in high fructose corn syrup is the same fructose that is in an apple or sugar cane. It's like glucose: glucose is glucose is glucose.

The two most commonly used forms of HFCS are roughly 50/50 fructose/glucose (HFCS42 is 42% fructose, 53% glucose, HFCS55 is 55%fructose, 41% glucose), similar to the fructose/glucose ratio in sucrose. Fructose and glucose are chemical identities. They aren't generalized names for broad classes of chemicals that vary greatly.

Don't be too hasty. Fructose comes in a variety of molecular structures. Hydrolyzed corn starch is used as the raw material for production of HFCS through enzymatic processes. Maybe, the type of fructose produced by enzymes isn't exactly the same fructose structure as that produced by plants in nature (at least in relative quantities)?

I'm not an expert, but I don't think we know enough about the digestive processes, to understand everything that happens when the body processes these different fructose molecules in quantities not normally found in nature.

It makes far more sense from a health stand point, to stick with the sugars our bodies are familiar with, consumed in packages our digestive systems know how to handle due to thousands of years of evolution.

Example of two different fructose molecules:
