Nutrition for Chronic Kidney Disease in Children

Diet plays an important role in preventing a worsening of chronic kidney disease and other health problems in children. Registered dietitians at Hassenfeld Children’s Hospital at NYU Langone offer guidance on how to limit nutrients that your child’s kidneys can no longer eliminate as needed.

Sodium

Excess amounts of sodium, or salt, can cause the body to retain water, which can lead to swelling and hypertension, or high blood pressure. Avoiding processed foods, including salty snacks and high-sodium frozen and fast foods, can help keep blood pressure under control.

Potassium

Your doctor may recommend limiting your child’s consumption of potassium. Although potassium is found in many nutritious foods, including a variety of fruits, vegetables, and beans, it can be difficult for the kidneys to eliminate. High levels can lead to heart rhythm disturbances, called arrhythmias.

Phosphorous

Children with chronic kidney disease cannot eliminate phosphorus adequately, leading to a buildup of this mineral. Excess phosphorous can pull calcium out of bones, making them weak. The doctor may discourage your child from eating foods that contain high levels of phosphorous, such as egg whites, popcorn, and many sodas.
