The kidneys have many functions, such as secreting hormones or regulating blood pressure. The most important function is to filter the blood and convert it into urine to remove old wastes, salts, and excess water from the body. When blood pooling in the body is about to enter the kidneys, it is filtered through the nephrons. Nephrons are composed of "glomeruli" (filament spheres) in which microvessels are intertwined like balls of yarn, and "renal tubules" through which filtered urine (original urine) flows.
In addition to old waste, the raw urine filtered by the glomerulus also contains electrolytes such as amino acids, sugars, salts, potassium, phosphorus, and magnesium. Therefore, 99% of the original urine will be industry email list reabsorbed into the body when it passes through the renal tubules, and finally only the old waste and excess water will be excreted in the urine. Even if you eat too much protein, the unused protein is usually filtered by the kidneys as old waste and eventually excreted. However, if you continue to consume too much protein, it will gradually put a heavy burden on the kidneys.
Animal experiments have shown that excessive protein intake can burden the filtration function of the glomerulus, which can lead to kidney damage. A condition in which the filtering function of the glomerulus is weakened and old waste cannot be adequately excreted from the body is called "renal failure". If you continue to eat a lot of protein, it will make the condition worse. Therefore, in the treatment of renal failure, considerable attention is paid to dietary regimens that limit the intake of protein. Based on these animal experime
