<human>:  How can I make sure my children are getting enough fiber in their diet?
<bot>: Start by including high-fiber foods in their meals and snacks. Whole grains, vegetables, fruits, nuts, and seeds are great sources of fiber. Look for products made with whole grain flour, such as bread and pasta. Make sure to buy snacks that are high in fiber, like popcorn, whole grain crackers, dried fruit, and nuts. For breakfast, serve oatmeal or another whole grain cereal, or put some fruit or nuts in yogurt or a smoothie. Finally, make sure to offer your children plenty of hydration to help fiber move smoothly throughout the digestive system.
