There's no such thing as a bad vegetable. But some have more vitamins and minerals. When packing your child's lunch, pick bright-colored veggies such as peppers, cherry tomatoes, broccoli, and carrots; they have more nutrients than cucumbers and celery. A healthy lunch is in the bag if you also add a protein, a fruit, and a whole grain. Send the whole fruit -- an apple rather than apple sauce -- so your child gets the extra vitamins from the peel. If your child buys lunch or snacks at school, teach him to make healthier choices. School lunches now have less salt and fat and more vegetables, fruits, and whole grains.
