found in the ward that many patients with renal insufficiency (abnormally elevated creatinine, urea nitrogen, etc.) are eating sea cucumber, because many people think that sea cucumber can nourish the kidney. This is a very wrong approach. Patients with renal insufficiency have an impaired ability to excrete metabolic waste products such as creatinine and urea nitrogen (these nitrogen-containing metabolic waste products all come from protein metabolism), so they should limit protein intake (low-protein diet). Sea cucumber contains a lot of protein, mainly collagen. Collagen has low nutritional value and poor human utilization, so it will produce more creatinine, urea nitrogen and other metabolites, so it is harmful to renal insufficiency.

　　Patients with renal insufficiency should reduce the amount of protein (30 to 40 grams per day), while ensuring the quality of protein (mostly high-quality protein from meat, eggs, and milk), that is, renal insufficiency Patients should consume foods rich in high-quality protein such as milk (250 ml per day), eggs (one per day) and meat (about 50 grams per day). At the same time, to reduce food intake (the quality of the protein in the food is not good), lotus root flour, wheat starch, clarified flour (also known as clarified noodles) is a gluten-free flour composed of wheat. It can be used to make a variety of Snacks such as shrimp dumplings, powdered fruit, intestines, etc.) metabolize all or part of the food.
