The Claim

Higher dietary fiber intake is associated with a 28% lower risk of developing metabolic dysfunction-associated steatotic liver disease (MASLD) over a median follow-up of 10.5 years in a cohort of 190,276 adults, and each additional gram of daily fiber intake is associated with a measurable reduction in liver fat content as quantified by MRI.

In plain English

People who consume more dietary fiber have a 28% lower risk of developing metabolic dysfunction-associated steatotic liver disease over about 10.5 years, and each additional gram of fiber per day is linked to a measurable decrease in liver fat measured by MRI.

See the scientific wording

Higher dietary fiber intake is associated with a 28% lower risk of developing metabolic dysfunction-associated steatotic liver disease (MASLD) over a median follow-up of 10.5 years in a cohort of 190,276 adults, with each additional gram of daily fiber linked to a measurable reduction in liver fat content as quantified by MRI.

Why this might work

When you eat more fiber, bacteria in your gut break it down and make a compound called butyrate. Butyrate travels to the liver and turns off signals that cause inflammation and fat buildup. This lets the liver burn fat instead of storing it, so less fat accumulates in the liver.

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

    People who ate more fiber from foods like whole grains and vegetables were much less likely to develop fatty liver disease, and their livers had less fat — even when scientists checked for other factors like genes or weight.
