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.
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.
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.
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.
What the research says
1 studyIn 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.
