The kidney is in charge of filtering the waste products and toxins as well as extra water in the blood. Protein will break down into waste product, which should be discharged by kidneys. High-protein foods will produce more waste products and this will increase the burden of kidney. So you should avoid high-protein foods. Meanwhile, high-quality protein foods should be consumed to keep normal nutritions. They will produce less waste products. Such foods includes egg white, milk, lean meat.

You should avoid high-sodium foods.

Sodium is an electrolyte that our body needs. But too much sodium is not good for the health of the kidney, especially the damaged kidney. The damaged kidney cannot well discharge the electrolyte and fluids. Too much sodium will cause sodium-fluids retention, which will increase swelling. Some patients with lupus nephritis may have high blood pressure. High-sodium is also a contributor of high blood pressure. So you should avoid high-sodium foods like processed foods, fast foods, restaurant foods and so on.

You should avoid high-potassium foods.
