Potassium can be found in many foods. Abnormal blood levels of potassium can be very dangerous as they may lead to serious heart
arrhythmias. Kidneys regulate the metabolism of potassium, making sure that its levels are appropriate. However, when your kidneys are not working properly, you often need to limit certain foods that can increase the potassium in your system.
If you need to limit your potassium, your doctor or dietitian will tell you how many milligrams (mg) you can have each day. They will also help you design a
low potassium diet.
Potassium is found in many foods, especially fruits and vegetables. If your doctor wants you to limit your potassium intake, you may want to consume less of the following foods that contain higher levels of potassium: Sweet potatoTomato juice, sauce, paste, and pureeBeet greensPotatoesWhite beansYogurtCanned clamsPrune juiceCarrot juiceSoybeans and lima beansBlackstrap molassesCertain fish such as halibut, yellowfin tuna, Pacific cod, rainbow troutWinter squashBananasCooked spinachPrunesDried peaches or apricotsMilk
