The Claim

Higher dietary plant protein intake is inversely associated with bone mineral density at the lumbar spine and total hip in Chinese adults, independent of animal protein intake, with effect sizes of -0.192 and -0.173, respectively.

Source: Gut microbiota mediated the curvilinear association between dietary animal protein intake and bone mineral density in Chinese adults.

In plain English

In Chinese adults, higher consumption of plant-based proteins is linked to lower bone mineral density at the lumbar spine and total hip, even when accounting for animal protein intake.

See the scientific wording

Dietary plant protein intake is inversely associated with bone mineral density at the lumbar spine and total hip in Chinese adults, independent of animal protein intake, with effect sizes of -0.192 and -0.173, suggesting that plant protein sources may not confer the same bone-supporting benefits as animal protein in this population.

Why this might work

When people eat more plant-based proteins, the bacteria in their gut change in a way that produces fewer compounds that help bones absorb minerals. This leads to less mineral buildup in the spine and hips over time, making bones slightly weaker.

  1. Study: Gut microbiota mediated the curvilinear association between dietary animal protein intake and bone mineral density in Chinese adults.

    In Chinese adults, eating more plant-based proteins like beans and tofu was linked to slightly weaker bones in the spine and hips, even when accounting for how much meat or dairy they ate. This suggests plant proteins might not protect bones as well as animal proteins in this group.
