Potassium is a mineral found in many of the foods you eat. It plays a role in keeping your heartbeat regular and your muscles working right. It is the job of healthy kidneys to keep the right amount of potassium in your body. However, when your kidneys are not healthy, you often need to limit certain foods that can increase the potassium in your blood to a dangerous level. You may feel some weakness, numbness and tingling if your potassium is at a high level. If your potassium becomes too high, it can cause an irregular heartbeat or a heart attack.
Ask your doctor or dietitian about your monthly blood potassium level and enter it here:
If it is 3.5-5.0………………………You are in the SAFE zone
If it is 5.1-6.0………………………You are in the CAUTION zone
If it is higher than 6.0……………..You are in the DANGER zone

The process of leaching will help pull potassium out of some high-potassium vegetables. It is important to remember that leaching will not pull all of the potassium out of the vegetable. You must still limit the amount of leached high-potassium vegetables you eat. Ask your dietitian about the amount of leached vegetables that you can safely have in your diet.
