Kidney insufficiency eat soy products, but should be moderate. Renal insufficiency refers to the decline in glomerular filtration rate due to various reasons, causing metabolite retention, manifested by water, electrolyte and acid-base balance disorders and systemic symptoms. Soy products form protein metabolites after human intake, and when renal function is impaired, the main manifestation is elevated urea nitrogen. Patients with renal insufficiency require a low-salt, low-fat, high-quality protein diet (protein intake ≤ 0.8 g/kg/d); reduce protein intake so as not to burden the kidneys and further damage renal function; therefore, soy products can be consumed in moderation. When patients find renal insufficiency, they should consult the hospital in time, find out the cause of the disease under the guidance of specialists, treat it in time, add or stop medication according to the doctor’s instructions, as well as guide the diet, and review it regularly.
