To review trends in dietary fructose consumption and delineate the biochemical mechanisms linking hepatic fructose metabolism to de novo lipogenesis, insulin resistance, and metabolic dyslipidemia.
Narrative synthesis of recent biochemical and epidemiological literature investigating dietary fructose, sucrose, and high-fructose corn syrup.
Evaluation of metabolic pathways in human and animal models focusing on hepatic carbohydrate flux, lipid synthesis, and circulating lipoprotein dynamics.
High hepatic fructose flux drives an elevated rate of de novo lipogenesis and triglyceride synthesis by delivering excessive glycerol and acyl precursors.
Perturbations in hepatic glucose metabolism and lipid accumulation induce profound systemic insulin resistance in both human and animal models.
Fructose-induced metabolic shifts stimulate hepatic and intestinal overproduction of atherogenic lipoprotein particles, directly promoting metabolic dyslipidemia.

No takes yet. Share an insight, caveat, or question.

Implication

Narrative review reveals that excessive dietary fructose triggers hepatic lipogenesis and insulin resistance in humans, indicating that widespread fructose sweeteners drive metabolic syndrome.
