> Excess anything. Excess anything doesn't cause metabolic disorders like fatty liver disease, diabetes, and dyslipidemia. Only fructose does that, and "excess" fructose means that 5 apples, or three prunes will put you over the top. > There's a distinct difference between fruit and sugar. Fruit contains sugar, fructose specifically. It takes very little of some fruits to damage your body. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2673878/ > We have demonstrated that a mechanism by which fructose induces postprandial hypertriglyceridemia is through increased hepatic de novo lipogenesis. It has long been established that in contrast to the metabolism of glucose, fructose metabolism is independent of phosphofructose kinase regulation; thus, its uptake by the liver and its metabolism to de novo lipogenesis substrate is not limited by energy status (cytosolic ATP and citrate levels). In addition, fructose may activate sterol receptor element–binding protein-1c independently of insulin, which activates genes involved in de novo lipogenesis.
