The Claim
When body mass index and waist circumference are statistically controlled, the association between vegetarian diet and hip bone mineral density is no longer significant.
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.
People who follow a vegetarian diet have similar hip bone mineral density as nonvegetarians when their body mass index and waist circumference are taken into account.
See the scientific wording
Body mass index and waist circumference are strong modifiers of the association between vegetarian diet and bone mineral density, such that when these anthropometric factors are accounted for, differences in hip bone density between vegetarians and nonvegetarians become negligible.
People with lower body weight and smaller waistlines put less physical pressure on their bones, especially in the hips. This reduced pressure signals the bones to slow down the process of building new bone tissue, leading to lower bone density. Vegetarians often have lower body weight and smaller waists, which explains why their hip bone density appears lower — once body size is accounted for, the diet itself does not further reduce bone density.
What the research says
1 studyVegetarians tend to have slightly lower hip bone density, but this is mostly because they tend to be thinner and have smaller waists — once you account for body size, the difference in bone density almost disappears.
