The Claim
Higher dietary fiber intake is inversely associated with liver fat content, and this association is stronger in individuals with higher body mass index and higher genetic risk scores for metabolic associated steatohepatitis.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who eat more dietary fiber tend to have less fat in their liver, and this link is stronger in individuals with higher body weight and higher genetic risk for fatty liver disease.
See the scientific wording
The inverse association between dietary fiber intake and liver fat content is stronger in individuals with higher body mass index (BMI) and higher genetic risk scores for MASLD, suggesting fiber may have enhanced protective effects in those most vulnerable to fatty liver disease.
When you eat more fiber, gut bacteria break it down into a compound called butyrate, which travels to the liver and turns off genes that cause inflammation and fat buildup, while turning on genes that burn fat, leading to less fat in the liver.
What the research says
1 studyFor people who are overweight or have a genetic risk for fatty liver, eating more fiber helps reduce liver fat even more than it does for others. The study found that fiber’s protective effect gets stronger the higher your risk factors are.
