The Claim
In adults aged 65 and above, higher total dietary protein intake is associated with a slight increase in bone mineral density at the spine and total body, with each additional gram of protein per day corresponding to a 0.0011 to 0.0015 g/cm² increase in BMD 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 dietary protein each day is linked to a small increase in bone mineral density at the spine and whole body, with each extra gram of protein per day associated with a 0.0011 to 0.0015 g/cm² rise in bone density after accounting for other lifestyle and nutritional factors.
See the scientific wording
In older adults aged 65 and above, higher total dietary protein intake is associated with slightly higher bone mineral density (BMD) at the spine and total body, with each additional gram of protein per day linked to a 0.0011 to 0.0015 g/cm² increase in BMD after adjusting for age, sex, physical activity, smoking, alcohol, calcium, vitamin D, and energy intake.
Eating more protein gives the body more building blocks to make bone tissue, and it also triggers a hormone that tells bone cells to lay down more mineral, making bones denser.
What the research says
1 studyOlder adults who eat more protein tend to have slightly denser bones, even when you account for other healthy habits — and this study found exactly that. But just taking protein pills for a few months didn’t make bones denser, which is a different question.
