Lupus nephritis is a kind of autoimmune disease. The immune complex will deposit on glomerular, causing kidney damage. In order to reduce kidney damage, the doctor will always suggest patients a proper diet. There are some foods that you have to avoid when you have lupus nephritis.
You should avoid high-protein foods.
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.
Some patients with lupus nephritis may be tested with high serum potassium. So this kind of patients should avoid high-potassium foods for not to increase potassium in blood. Such foods you should avoid includes bananas, apples, watermelons, spinach, potato, eggplant, corn, bens and so on.
You should avoid high-phosphorus foods.
Kidneys also plays an important role in keeping electrolyte balance. Because of damage caused by the deposition of immune complex, the kidney fails to keep electrolyte balance. So patients should avoid high-phosphorus foods like cheese, chocolate, ice cream, legumes, nuts and seeds.
