The Claim

Daily consumption of 80 grams of fructose or sucrose for 7 weeks increases the basal hepatic fractional secretion rate of fatty acids by approximately 2-fold compared to a control group in healthy men, indicating enhanced hepatic de novo lipogenesis, whereas the same amount of glucose does not produce this effect.

Source: Fructose- and sucrose- but not glucose-sweetened beverages promote hepatic de novo lipogenesis: A randomized controlled trial.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Cause and effect
1 study reviewed
In plain English

If healthy men eat 80 grams of fructose or table sugar every day for 7 weeks, their liver starts making and releasing about twice as much fat as before—but eating the same amount of plain glucose doesn’t do that.

See the scientific wording

Daily consumption of 80 grams of fructose or sucrose (a fructose-glucose disaccharide) for 7 weeks increases basal hepatic fractional secretion rate of fatty acids by approximately 2-fold compared to control in healthy men, indicating enhanced hepatic de novo lipogenesis, while the same amount of glucose does not produce this effect.

What the research says

1 study
  1. Study: Fructose- and sucrose- but not glucose-sweetened beverages promote hepatic de novo lipogenesis: A randomized controlled trial.

    This study found that drinking drinks with fructose or table sugar (sucrose) every day for 7 weeks made the liver produce more fat, but drinking drinks with just glucose didn’t — exactly what the claim says.
