The Claim
Higher dietary plant protein intake is associated with lower bone mineral density at the lumbar spine and total hip in Chinese adults aged 18–64, with effect sizes of -0.192 and -0.173, respectively, independent of animal protein intake.
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 aged 18–64, higher consumption of plant protein is linked to lower bone mineral density at the lumbar spine and total hip, with measurable reductions of 0.192 and 0.173 standard deviations, respectively, after accounting for animal protein intake.
See the scientific wording
Higher dietary plant protein intake is associated with lower bone mineral density at the lumbar spine and total hip in Chinese adults aged 18–64, with effect sizes of -0.192 and -0.173, respectively, suggesting a potential negative association independent of animal protein intake.
Eating more plant-based proteins changes the types of bacteria in the gut, which reduces the amount of calcium the body can absorb from food. This causes bones to break down more than they rebuild, leading to lower bone density in the spine and hips.
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 they ate. This suggests plant proteins might not help bones as much as animal proteins in this group.
