Potassium is a mineral in most foods. It helps the nervous system, the heart, and keeps muscles moving. Potassium also helps balance the water in the body.
Sometimes the potassium in your child’s diet needs to be watched. Your care team may ask you to increase or decrease the potassium your child eats by encouraging or limiting certain foods. The foods highest in potassium are fruits, nuts, milk, and vegetables. Larger serving sizes will increase the amount of potassium in the food. Read food labels and watch serving sizes to help control the amount of potassium in your child’s diet. Find more information on food sources of potassium.
