If a child always has to eat vegetarian meals, problems can develop. Vitamin B12, for example, is just found in foods of animal origin. This means: meat, liver, kidneys, most cheeses and fish and shellfish. If one parent insists on a vegetarian diet and other parent becomes concerned, I would suggest a two week diet history is kept and the results discussed with a dietitian. These trained individuals can generally be found in children's hospitals and general hospitals. A daily multivitamin is important for children, but that alone is not the answer. According to the physician, Dr. Henry Legere " a child would need to eat anywhere from three to seven times as much non-meat protein to get the amount of protein found in a single serving of meat or cheese." Most little children can not eat that amount of food at a meal.
One of the things I always did as part of my general routine physical examination was to take a diet history. I have been told by many medical students and residents that I am the only doctor they ever heard do that. I have been amazed at the meals some children eat each day. I believe I was able to cure a lot of irritability and other problems by asking about diets. I often had to suggest ways that children could be given better meals by outlining how meal plans could be made on weekends and the shopping done to get all the necessary items. "I agree with the old statement, "We are what we eat." Fast foods can be easy, but can also be harmful if that is all kids eat. School lunches should be nutritious but I am not sure they always are. Budgets can play a large part in what children receive, so as a parent I would want to find out what the children are given if they eat lunch at school.
