Did you know that a low-salt diet is good for your kidneys?

1. Reduce the burden on kidneys

Excessive salt intake can lead to water and sodium retention in the body, increase blood volume, and require the kidneys to work harder to excrete excess salt and water.

Salt restriction can reduce the filtration and reabsorption burden on the kidneys and help maintain normal kidney function.

2. Lowers blood pressure

A high-salt diet is one of the important factors leading to high blood pressure. High blood pressure can damage the small blood vessels in the kidneys, affecting the blood supply and function of the kidneys.

Limiting salt intake helps control blood pressure, thereby reducing damage to the kidneys caused by high blood pressure and lowering the risk of kidney disease.

3. Reduce proteinuria

For patients who already have kidney disease, salt restriction can reduce proteinuria, one of the key signs of kidney damage.

Reducing salt intake can reduce glomerular pressure, improve glomerular filtration function, and thus reduce protein leakage.

4. Delay the progression of kidney disease

During the development of chronic kidney disease, salt restriction can slow the rate of renal fibrosis and sclerosis.

It helps protect the remaining nephrons, prolong the compensatory function of the kidneys, and delay the progression of kidney disease to renal failure.

5. Prevent kidney stones

A high-salt diet can increase urinary calcium excretion and make kidney stones more likely to form.

Salt restriction can lower urinary calcium concentration, reduce the risk of kidney stones, and protect the kidney's excretion channels.

In summary, salt restriction has many important benefits for kidney health and is one of the important measures to protect the kidneys and prevent and treat kidney disease.
