Macro partitioning
High dietary fructose intake promotes non-alcoholic fatty liver disease (NAFLD) and hepatic insulin resistance by stimulating de novo lipogenesis via GLUT2 and GLUT5 transporters.
Limiting high-fructose corn syrup and excessive free fructose in processed foods is more effective for preventing liver fat accumulation than limiting glucose alone, as fructose uniquely drives hepatic lipogenesis.
StrongSupportsHIGH confidence
Enhanced fructose consumption... leads to elevated accumulation of saturated fatty acids and enhanced gluconeogenesis rates in the liver, eventually inducing liver steatosis... The lipogenic features of fructose lead to the development of NAFLD and, as a consequence, to increased hepatic insulin resistance
Why this rating
Supported by multiple studies cited regarding fructose metabolism, NAFLD, and genetic variants.
