Fatty fish such as salmon, mackerel, sardines and herring are foods rich in omega-3 fatty acids. This is an unsaturated fat that has anti-inflammatory and improved circulatory function effects. Many medical studies have shown that scientific consumption of fatty fish helps improve the blood filtration function of the kidneys and prevent the progression of chronic kidney diseases.
According to the World Health Organization, a diet rich in omega-3 fatty acids can reduce inflammation throughout the body - a factor that contributes to kidney tissue damage. A study by the National Institute of Diabetes and digestive and kidney Diseases (NIDDK) shows that supplementing fatty fish twice a week helps reduce the urinary protein index - an index that indicates the extent of damage to the renal plateau. This means that the kidney's blood filtration function has improved significantly.
Research also shows that replacing red meat with fatty fish in the diet reduces the risk of developing chronic kidney disease by up to 35%. Thanks to their ability to lower blood pressure and regulate blood fat, fatty fish indirectly help the kidneys reduce the pressure during the blood filtration process.
However, to achieve optimal results, fish should be processed with healthy methods such as steaming, boiling or baking instead of frying. At the same time, you should choose fish caught naturally instead of fish raised to limit the risk of infection with heavy metals such as mercury - a factor that causes kidney poisoning.
Eating fatty fish properly not only supports the cardiovascular system but also helps improve the filtering function of the kidneys through anti-inflammatory mechanisms, stabilizing blood pressure and reducing urinary protein. This is a reliable nutritional strategy and has been internationally recognized by science.
