The Claim
In healthy 5–6-year-old children, a lacto-ovo-vegetarian diet is associated with significantly higher bone alkaline phosphatase and C-terminal telopeptide of type I collagen levels and a lower osteocalcin-to-CTX-I ratio compared to an omnivorous diet, despite no difference in bone mineral density.
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.
Children aged 5–6 who eat a lacto-ovo-vegetarian diet have higher levels of bone alkaline phosphatase and CTX-I, and a lower osteocalcin-to-CTX-I ratio than children who eat an omnivorous diet, even though their bone mineral density is the same.
See the scientific wording
In healthy 5–6-year-old children, a lacto-ovo-vegetarian diet is associated with significantly higher bone turnover markers—bone alkaline phosphatase (BALP) and C-terminal telopeptide of type I collagen (CTX-I)—and a lower osteocalcin-to-CTX-I ratio compared to omnivorous children, despite no difference in bone mineral density, suggesting altered bone remodeling dynamics that may reflect adaptive metabolic regulation rather than bone loss.
Children who eat a lacto-ovo-vegetarian diet have similar muscle mass as children who eat meat, and their muscles pull on their bones during movement. This pulling activates bone cells that build new bone and break down old bone at the same time, raising signals of both processes. At the same time, their bones produce a form of osteocalcin that does not bind well to minerals, which changes how bone hardens without weakening it.
What the research says
1 studyKids who eat vegetarian food with dairy and eggs have higher levels of certain body signals that show their bones are breaking down and rebuilding more than in kids who eat meat — but their bones are just as strong. This means their bodies might be adjusting how they keep bones healthy without making them weaker.
