The Claim

Fiber intake is associated with higher bone mineral density at the total hip and femoral neck in women based on cross-sectional analysis, and with lower femoral neck bone mineral density in men based on longitudinal analysis.

In plain English

In women, higher fiber intake is linked to greater bone mineral density in the hip and femoral neck, while in men, higher fiber intake is linked to lower bone mineral density in the femoral neck.

See the scientific wording

Fiber intake is associated with higher bone mineral density at the total hip and femoral neck in women in cross-sectional analysis, but with lower femoral neck BMD in men in longitudinal analysis, indicating sex-specific and time-dependent relationships between fiber and bone health.

Why this might work

Eating more fiber changes the bacteria in the gut, which produce chemicals that reduce body-wide inflammation and shift hormone levels. In women, this leads to more bone-building activity, but in men, it reduces bone-building signals and increases bone loss over time.

    In women, eating more fiber was linked to stronger hip bones, but in men, eating more fiber over time was linked to weaker hip bones — the study found this exact difference.
