Potassium performs important functions in the body. It is involved in muscle contraction, transmission of nerve impulses and regulation of blood pressure. While consuming it is important, if you suffer from certain medical conditions such as hyperkalemia, you may need to avoid or limit foods high in this mineral.

This is usually not an easy task since micronutrients are found in a wide variety of fruits, meats and vegetables. To prevent dietary changes from causing more problems than solutions, must be developed, recommended and supervised by a medical professional. Restricting foods may come with side effects that need to be prevented and counteracted.

What is hyperkalemia and why does it occur?

This is an excess of potassium levels in the blood. For diagnosis, it is necessary to conduct a laboratory test and confirm the presence of more than 5 millimoles per liter (mmol/L) of the trace element.

The normal range is 3.5 to 5 mmol/L.

Mild cases of hyperkalemia may go undetected because they do not always present with obvious symptoms and are only rarely detected by blood tests. However, in more serious circumstances, the following signs may appear:

  • Nausea
  • Vomit
  • Insomnia
  • Tremor
  • tingling
  • Chest pain
  • Muscle weakness
  • Decreased cardiac activity

Although the causes vary, it is most often associated with kidney disease. When the kidneys do not function properly, potassium is not excreted properly in the urine and accumulates in the blood..

This can occur, among other things, due to conditions such as chronic kidney disease, the use of certain medications (such as diuretics), and conditions that cause rapid cell destruction, such as cancer. This can also occur in cases of adrenal insufficiency and heart failure.

Excessive potassium intake is rare, but if it occurs, it can lead to elevated potassium levels in the blood. Especially if you suffer from a disease that makes it difficult to eliminate.

In addition to the recommendations that a nutritionist develops for us, we will need to know which foods are richest in potassium so as not to make mistakes. According to the National Kidney Foundation criteria, a product contains too much of this mineral when contains more than 200 milligrams of nutrients per 100-gram serving.

Let’s see the list in detail. For reference values, data from the US Department of Agriculture was taken, which indicates the number of milligrams of the mineral per 100 grams of the food product mentioned (this is the number we will consider in parentheses).

  • Fruits: pear, apricot, peeled apple, juice or puree, red fruits (blueberries, blackberries, strawberries and raspberries), grapefruit, pineapple and watermelon.
  • Raw vegetables: onions, cauliflower, celery, corn, cucumbers, peppers and lettuce.

Dietary restrictions are not the only treatment

One of the first measures to reduce potassium levels in the blood is to limit it in food. And although it may slow the progression of kidney disease, This is not a curative treatment.

The work, published in the official journal of the European Kidney Association, suggests other potential clinical factors beyond diet should be taken into account. In turn, other studies suggest that plant foods may have certain qualities that are beneficial for patients with kidney disease, so eliminating them from the diet is more of a problem than a help.

According to the condition, Your doctor may recommend different approaches for hyperkalemia. Sometimes diuretics are prescribed to increase the excretion of the mineral in the urine. There are also resins, such as polystyrene sulfonate, that bind to nutrients in the digestive tract and excrete them in the stool.

In more severe cases, a combination of insulin and glucose is used intravenously. If kidney disease is very advanced, dialysis will be indicated.

Finally, It is extremely important to consult a medical professional determine the causes of high potassium in the blood. The nutritionist will then develop a diet, but we will have to apply other measures and perhaps even take medications.
