Vegetarian diets are healthy for kids, as long as they get key nutrients needed to grow healthy and strong. It’s important your child understands that a "vegetarian" diet means a vegetable-based diet. Excellent vegetarian sources of iron include soy, lentils, chickpeas, black-eyed peas, beans and seeds like sesame and hemp. Sampling vegetarian eating one day a week lets them test it out and see if it is something they would like to continue. Be sure to use recipes from a vegetarian eating plan, rather than just leaving out the meat.
