Such Foods Are Seen as Kidney 'Killers’ by DoctorsSome foods are seen as kidney killers by doctors. Without attention, they may cause further kidney damage. In this article, let’s see about foods high in potassium.

Potassium has important physiological functions in human body, such as participating in cell metabolism, maintaining osmotic pressure and acid and alkali balance, and regulating humoral balance. The normal blood potassium concentration is 3.5-5.5mmol/L, and when the blood potassium content is higher than 5.5mmol/L, it is called hyperkalemia.

Under normal circumstances, 80-90% of potassium is excreted by the kidneys. For people with normal kidney function, hyperkalemia does not appear. When kidney function is abnormal, you should always pay attention to the concentration of blood potassium.

Symptoms of hyperkalemia

The main clinical manifestations of hyperkalemia are cardiovascular and neuromuscular symptoms. The severity of hyperkalemia depends on the degree and speed of blood potassium elevation, the presence of plasma electrolyte and water metabolic disorders.

With the increase of blood potassium concentration in the body, some symptoms will appear, such as finger paralysis, limb weakness, chest tightness, blood pressure drop, extreme tiredness, lethargy, arrhythmia, serious cardiac arrest, or even death.

Precautions on diet

The intake of potassium mainly comes from food. Because kidney failure patients have no or little urine, potassium intake cannot be excreted in the urine so that it accumulates in the blood. Therefore, in order to control the blood potassium, in addition to adequate dialysis, the diet should also be paid more attention, especially to eat less foods high in potassium.

Most of the food contains potassium. Beans, vegetables and fruits are higher, rice noodles are second, eggs are less.

Common food of high potassium:

Vegetable: spinach, rape, leek, celery, green pepper, eggplant;

Fruit: banana, longan, pomegranate, orange, cantaloupe;

Homonemeae: mushroom, mushroom, laver, seaweed.

Tips for potassium removal from foods

When choosing food, avoid foods high in potassium. Besides, there are some tips to help remove potassium from foods.

Potassium ions are soluble in water. For leafy vegetables with high potassium content, you can clean the vegetables first, cut them and soak them in water for 30 minutes, change the water several times, or blanch them first, discard the juice and cook them, reducing the potassium by 1/2.

And for potatoes, cut them into small pieces or shreds, soak in water and change the water constantly, reducing the potassium by 1/2 to 2/3.

Vegetable soup is high in potassium. Don't mix rice with vegetable soup or drink it. Also, freezing foods high in potassium can remove some of the potassium.
