Chronic nephritis is a group of glomerular diseases caused by a variety of etiologies, with clinical manifestations such as proteinuria, hematuria, edema, hypertension, etc. The urinalysis is dominated by proteinuria, tubular, red blood cells, and generally has a long duration of disease. The purpose of dietary therapy is to supply reasonable nutrition to enhance body resistance, reduce attack triggers, and prevent infection and deterioration of the disease. In general, patients with chronic nephritis without significant renal impairment, with normal blood pressure, only need to control the sodium intake in the diet throughout the day within 2000 mg (equivalent to about 5 grams of salt), other dietary content does not need to be too strictly controlled, in order to avoid long-term restriction of the diet brought about by physical weakness, reduced resistance and other adverse consequences. The daily protein supply of such patients is about 1.0g/(kg-d) and energy supply is about 30-35kcal/(kg-d) as standard, and fresh vegetables and fruits rich in vitamins should be consumed. In addition, a salt-free (less than 1000 mg sodium/day) or low-sodium diet (less than 500 mg sodium/day) is required depending on the patient’s degree of edema. In the course of chronic nephritis, if the kidney function deteriorates rapidly, the diet should be adjusted in time with the degree of kidney function impairment (to be done under the guidance of a dietitian). So how exactly should chronic nephritis patients choose the right food to reasonably match their three meals a day? The food we eat everyday is divided into five categories, namely cereals and potatoes, vegetables and fruits, livestock, fish, eggs and milk, soybeans and nuts, and fats and oils.

Only a diet consisting of a variety of foods can meet the body’s needs for energy and various nutrients. Cereals and potatoes are rich in carbohydrates and are the most economical source of energy for the body, as well as an important source of B vitamins, minerals, protein and dietary fiber. It is recommended that patients with chronic nephritis consume 250-300g of cereals, 50-100g of potatoes and mixed beans every day. Fresh vegetables and fruits are an important source of vitamins, minerals and dietary fiber. Meals with vegetables and fruits every day, daily intake of vegetables 300-500g, fruits 200-350g, variety is not limited. Fish, poultry, eggs and lean meat are rich in high-quality protein, lipids, fat-soluble vitamins, B vitamins and minerals.
