The Claim
In adults aged 65 and above, higher intake of animal protein is associated with higher bone mineral density at the spine and total body, with each additional gram per day of animal protein intake linked to a 0.0011 to 0.0017 g/cm² increase 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 animal protein is linked to slightly higher bone mineral density in the spine and entire body, with each extra gram of animal protein per day corresponding to a small increase in bone density measurements.

In older adults aged 65 and above, higher intake of animal protein is associated with higher bone mineral density at the spine and total body, with each additional gram per day linked to a 0.0011 to 0.0017 g/cm² increase in BMD after adjusting for age, sex, physical activity, smoking, alcohol, calcium, vitamin D, and energy intake.
Eating more animal protein raises the levels of amino acids in the blood, which signals the body to produce more insulin-like growth factor 1. This hormone tells bone cells to build more bone tissue, making bones denser over time.
What the research says
1 studyOlder adults who ate more meat, dairy, or eggs had slightly denser bones than those who ate less, even when other healthy habits were taken into account. But giving them extra protein pills for a few months didn’t make their bones denser.
