Kidneys are organs heavily affected by daily diet. Some familiar foods, if used regularly, can increase the burden on the kidneys and accelerate the decline in function of this organ.
The first food group to note is preserved foods with high salt content such as pickled mustard greens, pickled eggplant, fermented tofu or smoked meat. Excessive sodium levels cause the body to retain water, increase kidney excretion pressure and affect the ability to regulate water - electrolytes.
In addition, purine-rich foods such as animal organs, concentrated meat broth and some seafood can increase uric acid production. When high uric acid levels in the blood last for a long time, these crystals easily deposit in the kidneys, causing damage to the kidney tube and increasing the risk of gout-induced kidney disease.
In addition, sugary and refined foods such as confectionery, milk tea, and sugary soft drinks are also not beneficial for kidney health. Consuming too much sugar for a long time can lead to metabolic disorders, insulin resistance, and damage the blood vessel system that nourishes the kidneys. Processed meats such as sausages, ham, bacon, or pre-packaged stews also contain many preservatives and additives, forcing the kidneys to work harder to metabolize and excrete.
Experts warn that kidney damage often occurs silently and accumulates. Frequent use of the above foods can gradually reduce kidney function over time. A diet that is too salty can easily cause a water-sodium imbalance, increasing the risk of chronic nephritis and renal artery cirrhosis. Meanwhile, prolonged high uric acid levels can lead to kidney stones, urinary tract obstruction, and even kidney failure.
For sugary foods, prolonged consumption also increases the risk of glomerular fibrosis and proteinuria - one of the early signs of kidney damage. Therefore, maintaining a balanced diet, limiting salt, sugar, processed foods and foods that are too rich in purines is an important solution to help protect kidney function and reduce the risk of chronic kidney diseases.
