Fructose is pretty bad for your liver, I remember my Organic Chem professor railing against it. There is so much conflicting evidence in food science, it can be VERY difficult to study the longterm effects of the consumption of certain foods. I have a good friend who has her masters in Dietetics, and is a Registered Dietician. She hates how demonized fruits are, and was just telling me how for years RDs have been trying to stop MDs from telling dietetics not to eat fruit. Whole, fresh fruits in moderate quantities are certainly good for you!
