Actually, you can get fatty liver from too much fructose, which may be what happened to Spurlock, since he was consuming tons of soda.
Quote:
Robert Lustig: That's correct. And then the last thing that fructose does in the liver is it initiates an enzyme called Junk one, and Junk one has been shown by investigators at Harvard Medical School basically is the inflammation pathway and when you initiate Junk one what happens is that your insulin receptor in your liver stops working. It's phosphorylated in a way that basically inactivates it, serum phosphorylation it's called and when your insulin receptor doesn't work in your liver that means your insulin levels all over your body have to rise. And when that happens basically you're going to interfere with normal brain metabolism of the insulin signal which is part of this leptin phenomenon I mentioned before. It's also going to increase the amount of insulin at the adipocyte storing more energy. And you put all of this together and basically you've got a feed forward system of increased insulin, increased liver fat, liver deposition of fat, increased inflammation -- you end up with non-alcoholic fatty liver disease. You end up with your inability to see your leptin and so you consume more fructose and you've now got a viscious cycle out of control.
In fact fructose, because of the way it's metabolised, is actually damaging your liver the same way alcohol is. In fact it's the exact same pathway, in fact fructose is alcohol without the buzz.
Norman Swan: So this is the obesity related fatty liver disease that people talk about?
Robert Lustig: Exactly.
