How is high fructose corn syrup metabolized in the body?

Answer 1

Yes it is extremely hard for the body to digest.

"The reason that high fructose corn syrup can be so dangerous to you is that your body is not designed to digest high fructose corn syrup. So while your body can digest sugar in just a day or so, it often takes three or four days to digest high fructose corn syrup."

The body can only digest 25 grams of corn syrup in one sitting, the equivalent to a can of soda. Any amount over 25 grams will turn directly into fat.

Answer 2

HFCS has been the subject of a study in lab rats, the control group was given sugar water, the test group was given water+HFCS. This was in addition to the regular diet of Rat Chow. Both groups were given the exact same amount of calories overall, and the same amount of calories in Rat Chow, the ONLY difference was the substitution of HFCS for sugar. The rats given HFCS gained 48% of their body weight in fat. This is the equivalent of a 200 pound person gaining 96 pounds. This was Princeton even.
