The Claim
Increased protein intake has no clinically meaningful effect on physical performance or bone health in older adults.
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 older adults, eating more protein does not improve physical performance or bone health.
See the scientific wording
Increased protein intake has likely no effect on physical performance or bone health in older adults, as only 2 of 12 studies showed a benefit for physical performance and only 1 of 4 for bone health, with most effect sizes near zero and no clinically meaningful improvements.
When older adults eat more protein, their muscles and bones do not respond with stronger growth or repair because their bodies no longer use extra protein to build more muscle or bone tissue. The cells that make muscle and bone stop reacting to higher protein levels, so strength and bone density stay the same.
What the research says
1 studyEating more protein doesn’t seem to help older adults walk faster, balance better, or strengthen their bones — even if they also exercise. The studies mostly found no real benefit for these things.
