The Claim
In adults aged 65 and above, higher intake of plant protein is associated with lower bone mineral density at the spine and total body, with each additional gram per day of plant protein intake linked to a 0.0010 to 0.0019 g/cm² decrease in bone mineral density after adjustment for age, sex, physical activity, smoking, alcohol, calcium, vitamin D, and energy 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 people aged 65 and older, consuming more plant protein is linked to slightly lower bone mineral density in the spine and entire body, with each extra gram of plant protein per day associated with a small reduction in bone density.
See the scientific wording
In older adults aged 65 and above, higher intake of plant protein is associated with lower bone mineral density at the spine and total body, with each additional gram per day linked to a 0.0010 to 0.0019 g/cm² decrease in BMD after adjusting for age, sex, physical activity, smoking, alcohol, calcium, vitamin D, and energy intake.
When more plant protein is eaten, the body breaks it down into acids that lower blood pH. To neutralize this, bones release minerals like calcium into the blood, which weakens bone structure over time.
What the research says
1 studyThis study found that older adults who eat more plant-based proteins like beans and lentils tend to have slightly lower bone density than those who eat less, even when other healthy habits are taken into account. The numbers match what the claim says.
