The Claim
Vegans exhibit a 3.7% lower broadband ultrasound attenuation (BUA) compared to omnivores, indicating reduced heel bone strength, despite lower urinary acid load, suggesting that non-acid-base dietary factors contribute to lower bone health in vegans.
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.
Vegans in the study had 3.7% lower heel bone strength as measured by broadband ultrasound attenuation than omnivores, even though their urine showed less acidity, indicating that factors other than dietary acidity affect bone strength in vegans.
See the scientific wording
Vegans in this study had significantly lower broadband ultrasound attenuation (BUA) by 3.7% compared to omnivores, indicating slightly reduced heel bone strength, despite having lower urinary acid load, suggesting that factors other than dietary acid-base balance may contribute to lower bone health in vegans.
Vegans consume less calcium and protein than omnivores, which reduces the raw materials needed to build and maintain strong bones. This causes bones to become less dense and more fragile over time, even when the body's acid levels are low.
What the research says
1 studyVegans in the study had slightly weaker heel bones than meat-eaters, even though their urine was less acidic — so something else about their diet or lifestyle, not acid levels, is likely affecting their bones.
