Introduction
For patients with 3+ proteinuria, dietary management should primarily focus on controlling sodium intake, limiting fat consumption, and moderately consuming high-quality protein. After kidney damage, kidney function is also impaired. Excessive intake of foods high in sodium, fat, or protein, although digestible and absorbable by the body, may easily increase the burden on the kidneys and adversely affect health.
For individuals with 3+ proteinuria, dietary management mainly involves controlling sodium intake, limiting fat consumption, and moderately consuming high-quality protein. Specific recommendations are as follows:
1. Control sodium intake
A urine protein level of 3+ indicates a significant amount of protein in the urine, which may be caused by kidney damage. It is recommended to restrict sodium intake because kidney function is often impaired when kidneys are damaged. Excessive sodium from sources such as table salt and soy sauce can accumulate in the body, increasing blood osmotic pressure and blood volume, thereby worsening the condition.
2. Control fat intake
When kidney function is impaired, it is important to avoid foods high in fat, such as cakes and fatty meats. Due to slowed kidney metabolism, excessive fat intake may increase the burden on the kidneys and hinder recovery.
3. Moderately consume high-quality protein
Foods high in protein are not easily digested and absorbed by the body, especially when kidney function is severely impaired. Excessive intake of protein-rich foods such as milk, eggs, and lean meat may further increase the workload on the kidneys. Therefore, protein intake should be carefully controlled to provide necessary energy without overburdening the kidneys.
In addition, it is beneficial to consume more foods rich in vitamins. However, diet alone can only help alleviate symptoms and cannot cure the disease. Therefore, it is essential to seek prompt medical evaluation to determine the underlying cause and receive appropriate treatment under a doctor’s guidance.
