The Claim
Higher dietary protein intake (≥15% of total energy) is associated with a 64% lower risk of clinical vertebral fracture over five years in older adults, independent of age, sex, race, calcium intake, physical activity, and osteoporosis medication use.
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 consume at least 15% of their daily calories from protein have a 64% lower rate of spinal bone fractures over five years compared to those with lower protein intake, even when accounting for age, sex, race, calcium intake, physical activity, and osteoporosis medications.
See the scientific wording
Higher dietary protein intake (≥15% of total energy) is associated with a 64% lower risk of clinical vertebral fracture over five years in older adults, independent of age, sex, race, calcium intake, physical activity, and osteoporosis medication use, suggesting a potential protective effect on spinal bone integrity.
Eating more protein helps the gut absorb more calcium from food, and it also increases a hormone called IGF-1 that tells bone-building cells to make more bone tissue. This makes bones denser and stronger, so they are less likely to break in the spine.
