Best Kind of Foods for People with Kidney Disease

About 10% of the world is suffering from kidney disease. Thus it is not a new phenomenon or illness. It is common and can happen to anybody. As small as the kidneys seem, they play very important roles in the human body’s metabolism. They sift out waste products from the body and are also known to be the brain behind the release of hormones that regulate blood pressure. The kidneys also carry out an important function in the production of urine and balancing other body fluids, among other essential tasks.

Some of the risk factors of kidney diseases include;

  • High blood pressure and diabetes
  • Obesity
  • Smoking
  • Sometimes, age
  • Gender
  • Genetics

When blood pressure shoots up and becomes too high, and when the blood sugar gets dangerously high, the blood vessels in the kidneys can be exposed to the risks of getting damaged, thereby reducing the blood vessels’ ability to function properly.

It becomes a problem when the kidneys begin to malfunction or develop certain problems, as waste products that are supposed to leave the body begin to build up or get accumulated within the body.

Thus, it is usually the case that people with kidney diseases stick to a particular pattern of feeding and also to certain kinds of special foods.

Kidney Disease and Its Special Diet

The degree of restrictions you get on what to and what not to eat depends on the degree of the damage to your kidneys. For instance, people who are in their early stages of kidney disease tend to get lesser dietary restrictions compared to those who have acute kidney failure, which is also known as end-stage renal disease.

If you happen to have any form of kidney disease, your Doctor can determine or suggest the best diet for your condition, depending on the stage or degree of your kidney damage.

However, for those who are suffering from advanced-stage kidney damages, it is advisable to follow a diet that would beat down the amount and production of waste in the body. In the medical field, it is called a renal diet.

The renal diet is famous for its ability to prevent the kidney from more damage and also boost the functions of the kidney.

As much as dietary restriction for kidney damage vary, it is important to note that people who have been diagnosed with kidney condition should monitor or restrict their consumption of foods that contain the following nutrients;

  • Sodium; Sodium is common in salt. A damaged kidney no longer has the ability to filter excess sodium in the body. When sodium contents get accumulated in the blood, the blood pressure begins to rise, leading to more health complications.
  • Potassium; As much as potassium plays a vital role in the body generally, its intake should be restricted in people with kidney damage.
  • Phosphorus; Phosphorus is an indispensable mineral in the body that is required for the proper functioning of the body organs. However, since a damaged kidney cannot get rid of excess phosphorus from the blood, it is important to eat foods that contain phosphorus with caution, as it can cause more harm to the body.
  • Protein; Another thing people with kidney disease may want to restrict their consumption is protein, as the wastes accumulated from protein metabolism cannot be filtered out by a damaged kidney. Nevertheless, on the other hand, those who are diagnosed with advanced-stage kidney disease and are undergoing dialysis may need more protein. This is why it is important to speak to your medical health provider about the diet that suits your condition, as there are varying diet requirements for varying stages of kidney disease.
