The Claim

Fructose consumption increases hepatic de novo lipogenesis (DNL) to a greater extent than glucose or high-fat diets in humans, leading to lipid accumulation in the liver that is associated with insulin resistance.

In plain English

Eating too much fructose—like the sugar in soda and fruit juice—makes your liver create more fat than other sugars or fatty foods do, and that extra fat can mess with how your body responds to insulin.

What the research says

1 study
  1. Study: Fructose and hepatic insulin resistance

    This study says that eating too much fructose (like in sugary drinks) makes your liver create more fat than glucose or fatty foods do, which can lead to insulin resistance — even without gaining weight.
