The Claim
Protein intake has no significant effect on hip bone mineral density in elderly women aged 65–77, regardless of calcium intake level.
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 elderly women aged 65–77, the amount of protein consumed does not change the density of bone in the hip, whether calcium intake is high or low.
See the scientific wording
Protein intake has no significant effect on hip bone mineral density in elderly women aged 65–77, regardless of calcium intake level, suggesting the hip may be less responsive to dietary protein than other skeletal sites.
In older women, the hip bone does not respond to more protein in the diet because its bone-building cells do not increase their activity even when amino acids are available. Other bones like the spine and arms do respond, but the hip bone’s cells remain unchanged.
What the research says
1 studyStudy: Protein intake: effects on bone mineral density and the rate of bone loss in elderly women.
In older women, eating more protein helped strengthen bones in the spine and arms, but not in the hip—even when they ate enough calcium. So, protein doesn’t seem to help the hip stay strong.
