A major meta-analysis found that a well-planned and adequately supplemented vegetarian or vegan diet can meet nutritional needs and promote healthy growth in children.[3] The authors reviewed evidence from multiple studies and reported that children on a plant-based diet often showed a more favorable cardiovascular profile, including lower total cholesterol and LDL cholesterol.[1][3] Children on a plant-based diet also consumed more fiber and some vitamins compared to children on an omnivorous diet.[1] The study identified common nutritional gaps in children without supplements or fortified foods, particularly low levels of vitamin B12 and calcium.[1][2] Some study findings also mentioned differences in bone mineral density and lower growth in vegan children (e.g. ~3 cm shorter height on average in one analysis) and a higher incidence of vitamin B12 deficiency in vegans compared to omnivores.[2] The authors emphasized that a plant-based diet for children is feasible only with careful planning and adequate nutrient supplementation.[3]
