The Youngest Vegetarians

Abstract

As the popularity of vegetarian diets increases, practitioners are likely to encounter vegetarian infants and toddlers. Vegetarian and vegan diets can be developed to meet nutrient needs and support growth of infants and toddlers. Key nutrients whose adequacy should be monitored in vegetarian/vegan diets include vitamin B12, calcium, vitamin D, iron, omega-3 fatty acids, and zinc. As for all infants, for the first 4 to 6 months, vegetarian infants should solely receive breast milk or a commercial infant formula. Fortified infant cereal or firm tofu is an appropriate first complementary food. Either of these, along with breast milk or formula, can meet needs for protein, iron, and zinc. Additional foods are introduced with timing similar to that for nonvegetarians. A variety of nutrient-dense foods should be introduced by 1 year of age. Fortified soy or cow’s milk should be the primary beverage postweaning. Growth should be monitored, and toddlers should be served a diet that includes high-calorie, low-fiber foods if growth appears to be faltering. Practitioners can play important roles in assessing the growth of vegetarian infants and toddlers, helping families make appropriate feeding choices, evaluating the need for supplements, and assisting with planning meals that will meet the needs of infants and toddlers.
