The Claim
Higher dietary protein intake at an increment of 1.0 g/kg/day is associated with a small but statistically significant increase in bone mineral density in middle-aged adults aged 40–69 years, as measured by ultrasound, independent of socio-demographic factors, dietary patterns, and physical activity levels.
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.
Middle-aged adults who consume an additional 1.0 gram of protein per kilogram of body weight per day have slightly higher bone mineral density measured by ultrasound, compared to those who consume less, after accounting for lifestyle and demographic factors.

More protein in the diet breaks down into amino acids that signal bone-building cells to make more bone tissue and harden it with minerals, leading to denser bones.
What the research says
1 studyThis study found that adults who eat more protein—about 1 gram per kilogram of body weight each day—tend to have slightly stronger bones, even when accounting for exercise, diet, and other lifestyle factors. It’s a clear link, not just a coincidence.
