Summary

Vegetarian children consumed less calories, protein, fat, zinc, and vitamin B12.
Vegan children were especially low in bone-strengthening calcium.
Plant-based diets offered heart health benefits and higher fiber intake.

Study: Plant Diets May Shortchange Kids' Nutrients

A large-scale study involving 48,000 children and adolescents has raised concerns about potential nutrient deficiencies in young vegans and vegetarians. Researchers found that children following plant-based diets often consumed lower amounts of essential nutrients like calories, protein, fat, zinc, and vitamin B12 compared to their omnivore peers.

Vegan children were particularly noted to have inadequate intake of calcium, vital for bone strength. While vitamin B12 often requires supplementation or fortified foods, calcium, iodine, and zinc also frequently fell at the lower end of recommended levels. This underscores the need for careful nutritional planning for children on these diets.

However, the study also acknowledged significant benefits of plant-based eating, including improved cardiovascular health, lower cholesterol, and higher intake of fiber, iron, folate, and vitamin C. Children on these diets also tended to be shorter with a lower body mass index, reducing risks of obesity and diabetes.
