(2,751 posts)I used to think "sugar is sugar" and that the exact chemical form didn't matter. Then I read more about biochemistry and came to a different conclusion.
Glucose and fructose are both natural sugars but they are metabolized differently. Almost every cell in the human body can use glucose for fuel, and glucose circulates in the bloodstream to provide energy to these cells. Fructose, in contrast, can pretty much be metabolized only by the liver. The primary way the energy in fructose is transferred to the rest of the body is by the liver first converting the fructose to fat and then that fat being carried as lipoproteins in the bloodstream.
I'm not preaching that "fructose is evil" or anything like that, simply that fructose and glucose are not created equal.
