The Claim
Higher protein intake is associated with higher bone mineral density in elderly women only when calcium intake exceeds 408 mg per day.
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, bone mineral density is higher with increased protein intake only if daily calcium intake is above 408 mg.
See the scientific wording
The association between higher protein intake and higher bone mineral density in elderly women is dependent on calcium intake exceeding 408 mg per day, indicating that protein’s potential benefit for bone density requires sufficient calcium intake.
When there is enough calcium in the body, protein breaks down into amino acids that signal bone-building cells to add more mineral to bone tissue. Without enough calcium, those signals do not trigger bone growth.
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 only helps bones get stronger if they also get enough calcium—specifically more than 408 mg per day. Without enough calcium, more protein doesn’t help bone density.
