Plant-based diets are gaining traction for kids, but are they healthy? A comprehensive analysis of over 48,000 children suggests they can be, but careful planning is key to avoiding nutritional gaps.
Growing Up Vegetarian or Vegan: What Parents Need to Know
A new study sheds light on the benefits and risks of plant-based eating for children.
- Vegetarian and vegan diets can offer health advantages for children, including higher fiber intake and improved cardiovascular health indicators.
- These diets require careful monitoring to prevent deficiencies in essential nutrients like vitamin B12, iron, calcium, and vitamin D.
- Supplementation and strategic food combinations are often necessary to ensure adequate nutrient intake.
- Overall growth and weight appear comparable between children on plant-based and omnivorous diets when the former are well-planned.
More and more families are choosing vegetarian and vegan diets for their children, sparking a common question: can kids truly thrive without animal products? The answer, according to recent research, is a qualified yes. A large-scale review published in the journal Critical Reviews in Food Science and Nutrition analyzed data from 60 studies involving more than 48,000 children following various dietary patterns. The findings indicate that well-planned plant-based diets can be appropriate for children, offering certain benefits, but also carrying specific risks if not carefully managed.
Researchers found that children adhering to vegetarian or vegan diets generally consume more complex carbohydrates, fiber, and micronutrients from fruits, vegetables, and legumes. This dietary pattern is also associated with lower intake of animal fats, potentially contributing to better cardiovascular health and lower cholesterol levels. But it’s not all sunshine and spinach.

Nutrient Deficiencies: The Biggest Concern
The study flagged a heightened risk of deficiencies in several key nutrients, particularly calcium, vitamin D, iodine, iron, zinc, and vitamin B12, especially in strict vegan diets. Vitamin B12, almost exclusively found in animal products, is crucial for nerve function and red blood cell formation. Its deficiency can lead to anemia, fatigue, weakness, and even neurological problems affecting memory, concentration, and mood.
Iron is another critical area. While plant-based foods contain iron, children on vegetarian and vegan diets often exhibit lower ferritin levels – a measure of the body’s iron stores. This increases the risk of anemia, which can negatively impact growth and cognitive development. Similarly, lower calcium intake was observed in vegan children, potentially compromising bone development and increasing fracture risk later in life.

Growth and Overall Health
What about a child’s growth and weight? The evidence suggests that, generally, there are no significant clinical differences between children on plant-based diets and those who eat meat. Specialists note that vegetarian and vegan children may consume less energy, fat, and protein, resulting in a slightly leaner build. However, most remain within a normal weight and height range for their age, provided their diet is carefully planned and supplemented.
The consensus among researchers is clear: children following vegetarian or vegan diets should receive professional nutritional guidance and, in many cases, supplements or fortified foods. Combining plant-based iron sources with vitamin C, for example, can improve absorption, though it may not always be enough.
Plant-based diets can offer benefits, including increased consumption of plant foods and potential cardiovascular protection. However, without careful planning and appropriate supplementation, the risk of nutritional deficiencies increases. The key, experts emphasize, isn’t the diet itself, but how it’s designed and monitored during the crucial stage of childhood.
