The Claim

Dietary fiber intake is inversely and linearly associated with the risk of metabolic associated steatohepatitis (MASLD), with no threshold below which the association ceases to exist.

Source: Dietary fiber intake, genetic predisposition of gut microbiota, and the risk of metabolic dysfunction-associated steatotic liver disease.

In plain English

Higher dietary fiber intake is consistently linked to lower risk of MASLD, and even small increases in fiber intake are associated with reduced risk without a minimum threshold.

See the scientific wording

The relationship between dietary fiber intake and MASLD risk follows a linear inverse pattern, with no evidence of a threshold below which fiber becomes ineffective, suggesting that even modest increases in fiber consumption may confer benefit.

Why this might work

When fiber is eaten, gut bacteria break it down to make butyrate, which travels to the liver and turns off genes that cause fat buildup and inflammation, leading to less fat in the liver.

    People who ate more fiber had less fat in their liver, and the more fiber they ate, the better it was—there was no minimum amount needed to see a benefit, even a little extra fiber helped.
