Membranous nephropathy large amount of urinary protein is not recommended to eat protein powder. Low salt and low fat high quality protein diet is recommended. Protein powder is mainly composed of soy protein, while patients with kidney disease are recommended to eat low quality animal protein in moderation, such as eggs, lean beef, fish and so on. Although a large amount of proteinuria in membranous nephropathy will lead to hypoproteinemia and protein should be supplemented. But eating nutrient-rich protein powder will instead further aggravate the burden on the kidneys, leading to more protein loss from the kidneys. The kidneys are already damaged, and when more protein is ingested, more protein passes through the glomeruli of the kidneys, and more protein leaks out of the glomerular filtration membrane, which also increases the damage to the glomerular filtration membrane. Therefore, it is recommended that patients with membranous nephropathy should go to the hospital in time. When there is a large amount of proteinuria, it is not recommended to eat protein powder to supplement protein. You can eat a small amount of egg white, milk, lean meat and other supplemental protein. However, it is not advisable to consume too much, otherwise it will aggravate the damage of the kidney instead.
