Diets
dairy is not required for bone health
In plain terms: Can you build strong bones without dairy?
Probably yes — dairy isn't strictly needed. Large studies find no clear link between more dairy and fewer hip or total fractures. But no trial has compared dairy-free and dairy-containing diets, and vegan diets have been linked to higher fracture risk, though that link is confounded.
🧭 Read this score with how it was built in mindWe re-read the papers behind these claims and corrected how each one is counted
A meta-analysis of calcium-plus-vitamin-D supplements had been counted as though it tested a dairy-free diet. Removed, the page holds observational studies in which high dairy intake shows no clear protection against most fractures. That is support by absence of benefit, and no trial has compared a dairy-free diet with a dairy-containing one on bone.

What the evidence shows
Leans support, but only by the absence of a clear benefit: no trial has compared a dairy-free diet with a dairy-containing one on bone outcomes. What counts is observational — meta-analyses in which the highest dairy intake showed no clear reduction in total or hip fracture (only vertebral), yogurt showed no association with hip fracture (HR 1.

We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
