The Claim

Among individuals of other racial groups in the U.S., dietary fiber intake above 33.45 grams per day is associated with significantly lower liver fat levels, while dietary fiber intake below this threshold is associated with a non-significant increase in liver fat levels, indicating a nonlinear relationship between dietary fiber intake and liver fat.

In plain English

In U.S. populations of other racial groups, consuming more than 33.45 grams of dietary fiber per day is linked to lower liver fat, while consuming less than this amount is linked to a small, non-significant rise in liver fat.

See the scientific wording

Among individuals of other racial groups in the U.S., dietary fiber intake above 33.45 grams per day is associated with significantly lower liver fat levels, while intake below this threshold is associated with a non-significant increase in liver fat, indicating a complex, nonlinear relationship.

Why this might work

When a person eats a lot of fiber, gut bacteria break it down into molecules that signal the liver to stop making fat and start burning it instead. At the same time, fiber slows down sugar absorption, which lowers insulin levels and prevents the liver from storing excess fat. Both processes work together to reduce fat buildup in the liver.

    For people in racial groups other than White or Black, eating more than about 33 grams of fiber a day is linked to less fat in the liver, but eating less doesn’t help much — this study found that exact number and pattern.
