The suggestion that fruit consumption leads to liver disease and / or heart disease (via inflammation) is a hard one to "swallow." Given that a large portion of the human race regarded fruit as a dietary staple (eg, Indians, Central and South American indigenous populations, etc), the concept that the human body is not well adapted to fruit consumption might not pass the intuition test.
There have been some studies which have shown a link between high consumption of HFCS / refined sugars and FLD and inflammation, but I don't think such a link has ever been found between fresh fruit and these ailments. The body reacts very differently to both. For example, if I down a soda laden with HFCS (or the new trend in sweeteners -- sugar), I get all the symptoms of a sugar rush, followed by a crash (the shakes, headache, hunger, etc). However, if I gobble down a 4 pound keitt mango, my body reacts to it in nearly the same way that it would to a regular meal -- which I've confirmed via a blood glucose monitor.
As palmcity pointed out, there are some individuals whose genetics cause them to react adversely to fresh fruit.( Some even have the curse of being allergic to mangoes!) But, I've yet to see any piece of scientific literature suggesting a link between high fruit consumption and disease in otherwise healthy individuals.
