Potassium Restriction Diet for Children

Potassium requirements for children with kidney failure

Potassium is very important to the body. But too much potassium in the blood can be harmful. When your child's kidneys don’t work well, too much potassium can build up in the blood. Your child's body receives potassium from the foods they eat. Some children may have trouble staying at a normal potassium level. They may need to limit or not eat foods with high amounts of potassium.

What foods are high in potassium?

Most foods contain some amount of potassium. It is important to stay away from 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:

Bananas
Prunes
Oranges
Potatoes
Orange juice
Sweet potatoes
Grapefruit juice
Tomato sauce
Cantaloupe

Use the following list as a guide in your child's food choices. Your child's healthcare provider or dietitian will let you know how much potassium your child can have each day.
