In rats fed fructose, sucrose, or glucose for one year, blood glucose levels were similar, but blood fructose levels were highest in the pure fructose group.

“you can see here is the water fed group the glucose fed group The sucrose fed group so that's a disaccharide of glucose and fructose and the fructose fed group notably the blood glucose levels for all of the intervention arms of this trial glucose sucrose and fructose are all pretty similar which is going to be important when we're looking at the hemoglobin A1c level and the fructosamine level you can see the blood fructose levels here not surprisingly the glucose fed group has a low level of blood fructose the sucrose fed group has a slightly higher level not 100x or anything like that and the fructose fed group pure fructose fed group has a higher level of fructose in their blood”
