Low potassium diet for babies and toddlers (1968)

Key points below

For babies and toddlers

Why does my baby need a low potassium diet?

Potassium is a nutrient found in food. It helps the body keep a regular heartbeat, contract muscles and control blood pressure. It also helps to control the body’s water balance.    
In kidney disease, and some other health conditions, potassium levels build up in the blood.  High levels may cause heart and muscle problems. A low potassium diet may help avoid these problems.

How do I choose foods with low potassium?

Many baby foods do have potassium information on the nutrition labels.  For those that do, use these numbers as guidelines to help you choose lower potassium infant foods:
Less than 150 mg per 4 ounce serving = low potassium
More than 150 mg per 4 ounce serving = high potassium
