Potassium requirements for children with renal failure
Potassium is very important to the body, but too much potassium in the blood can be harmful. When your child's kidneys do not work well, too much potassium can build up in the blood. Your child's body receives potassium from the foods he or she eats. If your child is having trouble maintaining a normal potassium level, it may be necessary to limit or avoid foods with high amounts of potassium.
What foods are high in potassium?
Most foods contain some amount of potassium. It is important to avoid or limit foods that are high in potassium if your child is on a low-potassium diet, or if your child's blood level of potassium is too high.
Some foods that are high in potassium include:
