A lacto-ovo vegetarian diet that includes milk and eggs can meet a child's needs for growth and development. For strict vegetarians, care must be taken in meal planning because the diet does not include animal products. Alternative food sources of some nutrients like protein, iron, calcium and vitamin B-12 must be used in this case. Also, the diet may consist of mainly low-calorie, high-fibre foods such as fruits, vegetables and grains. These foods are healthy but can fill up the stomach before the child has eaten enough protein-rich foods. A registered dietician can provide helpful information about vitamin and mineral supplements, meal planning and the number of calories and protein needed for growth and development
