Potassium: In patients with CRF, the ability to eliminate excessive amounts of potassium is decreased. If the potassium level in the blood is elevated, it causes complications. Potassium is found naturally in almost all foods of both plant and animal origin. Salt substitutes in the market may contain potassium and labels should be checked. Two methods of reducing potassium (leaching) in the foods are given below:

• Method 1: Wash, peel and cut vegetables into small pieces. Soak in warm water for 2-3 hours. Discard water. Add large volume of fresh water and cook vegetables. Discard water.
• Method 2:Peel vegetables and cut into small pieces. Bring to a boil in a large quantity of water. Discard water and cook in a large volume of fresh water. Discard excess water.
