Vegetable protein itself will not harm the kidney, but if the patient has kidney disease, too much vegetable protein intake will lead to the aggravation of kidney disease.
If kidney function is normal and there is no underlying kidney disease, plant protein intake is not harmful to the kidney. However, if the kidneys are diseased, then a vegetable protein diet will aggravate the increase of urinary protein.
Vegetable protein harms the kidneys because the bioavailability of vegetable protein is much lower than that of animal protein, thus consuming too much vegetable protein will increase the metabolic burden on the kidneys, cause the elevation of urea nitrogen and other toxins, and further increase the amount of protein leakage, which promotes the development of kidney disease.
For patients with kidney problems must pay attention to reduce the intake of plant protein, common plant protein of the main foods are peas, red beans and other legumes, except soybeans and soy products, and corn, wheat, rice and other grains.
If there are patients with kidney disease should be in the regular hospital to receive professional physician treatment advice and dietary guidance.
