Protein needs to be processed by the liver and converted into human substances. At the same time, protein produces nitrogen-containing substances such as ammonia, urea and inosine during metabolism in the body, which need to be excreted through the kidney. If you take too much, it will increase the burden of liver and kidney and have a negative impact on the human body. Especially in patients with diabetes, nephritis, renal insufficiency and other diseases, the degree of kidney damage is more serious, and proteinuria is a symptom.
