Summary:
A University of Helsinki study (MIRA2) examined bone health in children aged 2–7 on vegan, vegetarian, and omnivorous diets. Key findings show vegan children had higher vitamin D intake due to fortified foods and supplements, but plant-based diets were linked to elevated bone metabolism markers. While calcium and vitamin D levels were adequate in Finnish vegans, protein intake was lower, raising questions about long-term bone health. The study underscores the importance of careful dietary planning for vegan families.
What This Means for You:
- Prioritize fortified foods: Choose plant-based dairy alternatives fortified with calcium and vitamin D to meet nutritional needs.
- Supplement wisely: Vegan children should take daily vitamin D supplements, especially in regions with limited sunlight.
- Consult a dietitian: Professional guidance ensures balanced amino acid and protein intake for growing children on plant-based diets.
- Monitor bone markers: Elevated parathyroid hormone levels in vegan children may warrant long-term bone health assessments.
Expert Opinion:
“While vegan diets can support bone health with proper fortification, the accelerated bone turnover observed in plant-based groups warrants further research—especially regarding protein quality and long-term skeletal outcomes,” says Dr. Suvi Itkonen, lead researcher on the MIRA2 study.

People Also Ask About:
- Can vegan children get enough calcium without dairy? Yes, through fortified plant milks, leafy greens, and supplements.
- How does vegan protein quality affect bones? Plant proteins may lack certain amino acids critical for bone formation.
- Is vitamin D deficiency common in vegan diets? Not in Finland due to widespread fortification, but risk exists elsewhere.
- What are signs of poor bone health in vegan kids? Elevated PTH levels or delayed growth may indicate issues.
