Patients with chronic renal failure should eat a low-protein diet, generally controlled at 0.6 grams of protein per kilogram of body weight per day, and 60% of this protein should come from high-quality protein. The so-called high-quality protein mainly refers to animal protein, because animal protein can supplement the body’s essential amino acids. Many patients with poor kidney function think they cannot eat soy products such as tofu and soy milk, which is actually a misleading. Patients eat 60% of high quality protein, the other 40% can come from other proteins, and soy products also contain a certain amount of essential amino acids. According to the measurement, animal protein contains 45% of essential amino acids, cereals such as rice and noodles contain 35% of essential amino acids, while the essential amino acid content of soy products is about 40%. Therefore, while ensuring adequate intake of animal protein, you can eat a certain amount of soy products, and some studies have shown that soy products contain phytohormones and other ingredients, which are protective of the kidneys.
