A person with chronic kidney disease may have to follow a low-potassium diet, according to the National Kidney Foundation. Healthy kidneys regulate the amount of potassium in the body, but when disease compromises the kidneys, potassium levels may reach dangerous levels in the body unless the individual limits intake of certain foods that can raise blood potassium levels.Continue Reading
Potassium is an essential mineral that helps regulate the heartbeat and keep muscles working correctly, explains the National Kidney Foundation. A person with normal kidney function can consume 3,500 to 4,500 milligrams of potassium per day, but a person with CKD must restrict his potassium intake to 2,000 milligrams per day or the level recommended by his physician.
While almost all foods contain some potassium, many foods contain high levels of the mineral, advises the National Kidney Foundation. Dried fruits and fruits such as bananas, mangoes, oranges and prunes contain high levels of potassium, while vegetables that are high in potassium include greens, acorn and butternut squash, legumes, mushrooms, and potatoes. In addition, nuts, dairy products, chocolate and bran products are high in potassium.
Portion size is key when it comes to limiting potassium in the diet, warns the National Kidney Foundation. Foods that are low in potassium can raise blood potassium levels if an individual consumes them in large quantities.Learn more about Nutrition & Diets
