The Claim

In mice fed a high-fat diet, supplementation with fructose or glucose increases hepatic expression of the pro-inflammatory markers NLRP3 and TNF-α and the fibrosis-related protein α-SMA.

Cause and effect
1 study reviewed
In plain English

In mice on a high-fat diet, adding fructose or glucose to their diet increases levels of specific proteins in the liver that are linked to inflammation and early scarring.

See the scientific wording

In mice fed a high-fat diet, supplementation with fructose or glucose leads to increased hepatic expression of pro-inflammatory markers (NLRP3, TNF-α) and fibrosis-related proteins (α-SMA), indicating that both sugars promote inflammation and early fibrotic changes in the liver.

Why this might work

Excess fat and sugar in the liver cause toxic fat molecules called ceramides to build up, which damages the energy factories inside liver cells. This damage releases harmful chemicals that turn on an inflammatory alarm system, which then signals scar-forming cells to activate and lay down fibrous tissue, leading to liver scarring and inflammation.

  1. Study: No Difference in Liver Damage Induced by Isocaloric Fructose or Glucose in Mice with a High-Fat Diet

    In mice eating a fatty diet, adding either sugar—fructose or glucose—made their livers more inflamed and scarred, just like the claim says. Both sugars did about the same amount of damage.
