Here's a list of the most important foods suitable for kidney diseases

Kidney disease is common and affects about 10% of the world's population. Kidneys are small organs but do many important jobs. They clean waste from the blood, release hormones that help control blood pressure, balance body fluids, and produce urine.

There are various causes of kidney disease. Diabetes and high blood pressure are key risk factors for kidney problems. Other factors include obesity, smoking, genetics, and age which increase the risk of kidney disease.

When kidneys don’t work right, waste builds up in the blood, including food waste. So, people with kidney disease need to follow a special diet.

• Diet and kidney disease :-

Diet limits for people with kidney disease vary depending on how much the kidneys are damaged. For example, early stage kidney patients have different diet restrictions than those in advanced stages.

Despite these differences, it’s generally advised that all kidney patients limit the following nutrients :-

• Sodium :-

Sodium is found in many foods and is a main component of table salt. Damaged kidneys can't get rid of extra sodium, which leads to high blood pressure. So, sodium should be limited to less than 2000 mg per day.

• Potassium :-

Even though potassium is very important, those with kidney disease need to limit it to avoid dangerously high levels in the blood. It's usually recommended to keep potassium under 2000 mg per day.

• Phosphorus :-

Phosphorus is a mineral found in lots of foods. Damaged kidneys can’t clear extra phosphorus, which can cause many problems for the body. So it’s advised to limit phosphorus to 800 to 1000 mg per day.

Protein is another nutrient that kidney patients may need to limit, because damaged kidneys can’t get rid of wastes from protein metabolism.

If you have any kind of kidney disease, you should talk to your healthcare provider about your diet and how to meet your nutritional needs in a way your kidneys can handle.
