The Claim
Adult vegetarians have slightly lower bone mineral density at the femoral neck, total femur, and lumbar spine compared to nonvegetarians, but these differences become statistically nonsignificant after adjusting for body mass index and waist circumference, indicating that anthropometric factors account for the observed variation in bone mineral density rather than dietary composition alone.
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.
Adults who follow a vegetarian diet have slightly lower bone mineral density in the hip and spine than nonvegetarians, but this difference disappears when accounting for body weight and waist size, meaning body measurements explain the variation more than diet type.
See the scientific wording
Adult vegetarians have slightly lower bone mineral density at the femoral neck, total femur, and lumbar spine compared to nonvegetarians, but these differences become statistically nonsignificant after adjusting for body mass index and waist circumference, suggesting anthropometric factors largely explain the observed variation rather than dietary composition alone.
People with smaller body size exert less force on their bones during daily movement, so their bones do not build as much density. This happens because bones respond to physical stress by growing stronger, and less stress means less growth.
What the research says
1 studyVegetarians have slightly lower bone density than meat-eaters, but that’s mostly because they tend to be thinner — once you account for body size, the difference mostly goes away.
