The Claim

In 5–6-year-old children, a lacto-ovo-vegetarian diet is associated with higher levels of carboxylated osteocalcin (Gla-OC) and a higher Gla-OC/Glu-OC ratio compared to an omnivorous diet, indicating altered vitamin K-dependent osteocalcin metabolism.

In plain English

Children aged 5–6 who eat a lacto-ovo-vegetarian diet have higher levels of carboxylated osteocalcin and a higher ratio of carboxylated to uncarboxylated osteocalcin than children who eat an omnivorous diet, suggesting differences in how vitamin K is used in bone metabolism.

See the scientific wording

In 5–6-year-old children, a lacto-ovo-vegetarian diet is associated with higher levels of carboxylated osteocalcin (Gla-OC) and a higher Gla-OC/Glu-OC ratio compared to omnivorous children, suggesting altered vitamin K-dependent osteocalcin metabolism, though the clinical relevance remains uncertain due to unmeasured vitamin K intake.

Why this might work

Children who eat plant-based foods, dairy, and eggs but no meat have more of a bone protein that is fully activated by vitamin K, which makes it bind better to bone minerals. This happens because their diet may provide less vitamin K or less of it that the body can use, so the bone cells make more of the activated form to compensate, even though their bones are just as strong.

  1. Study: Assessing Bone and Adipose Tissue Biomarkers in 5–6-Year-Old Polish Children Adhering to Vegetarian and Traditional Diets

    Kids who eat vegetables, dairy, and eggs but no meat had more of a special bone protein that needs vitamin K to work properly, compared to kids who eat meat — even though their bones were just as strong.
