The Claim
Older adults with a dietary protein intake of at least 15% of total energy intake have 1.8% to 6.0% higher baseline bone mineral density at the hip, femoral neck, and lumbar spine than older adults consuming less than 13% of total energy as protein.
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.
Older adults who get at least 15% of their daily calories from protein have 1.8% to 6.0% higher bone mineral density in the hip, femoral neck, and lower spine than those who get less than 13% of their calories from protein.
See the scientific wording
Older adults with a dietary protein intake of at least 15% of total energy intake have 1.8% to 6.0% higher baseline bone mineral density at the hip, femoral neck, and lumbar spine compared to those consuming less than 13% of total energy as protein, suggesting that current dietary recommendations may underestimate protein needs for skeletal health in this population.
Eating more protein helps the gut absorb more calcium from food, and it also causes the body to produce more of a hormone called IGF-1. This hormone tells bone-building cells to work harder, making bones denser and stronger by adding more mineral to the bone structure.
What the research says
1 studyOlder adults who got at least 15% of their daily calories from protein had stronger bones at the hip and spine than those who got less than 13%, suggesting current protein guidelines might be too low for keeping bones strong.
