The Claim
In elderly women aged 65–77 with calcium intake exceeding 408 mg per day, higher dietary protein intake (average 72 g/day) is associated with 5–7% higher bone mineral density at the spine, midradius, and total body, but not at the hip.
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.
Among elderly women over 65 who consume more than 408 mg of calcium daily, those who eat about 72 grams of protein per day have 5–7% higher bone mineral density in the spine, midradius, and total body compared to those with lower protein intake, but no difference is observed in the hip.
See the scientific wording
In elderly women aged 65–77 with calcium intake exceeding 408 mg per day, higher dietary protein intake (average 72 g/day) is associated with 5–7% higher bone mineral density at the spine, midradius, and total body, but not at the hip, suggesting protein may support bone density under conditions of adequate calcium intake.
When there is enough calcium in the diet, more protein increases the amount of calcium kept in the bones and helps build stronger bone structure in areas like the spine and forearm, but not in the hip where bone turnover is slower and less responsive.
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 who eat enough calcium, eating more protein is linked to slightly stronger bones in the spine, forearm, and whole body — but not in the hip. The study found this exact pattern.
