Calory

Calory supply should be at least 30~35kcal/kg/d(Icar=4.1868J), because only with enough calory supply, can excessive decomposition of protein be prevented. In addition, it ensures enough energy for synthetic protein.

The combination of low protein diet and essential amino-acid or α-keto acid (a-KA)

Protein intake ranges according to the remaining kidney function. In principle, protein intake for patients without dialysis is 0.6-0.8g/kg.d. It is better to supplement essential amino-acid or α-keto acid. It has been proved that α-keto acid. Improves synthesis and storage of protein. Meanwhile, during the transforming process into essential amino-acid, α-keto acid can increase the use of urea nitrogen, which contributes to nutritional state and delay the process of kidney function degeneration.

Control salt consumption

Salt consumption is closely related to condition changes. If there is hypertension or severe edema, low salt diet is required. Low salt intake refers to 2g/d of salt or 10mL/d of soybean sauce. If there is frequent urination, measure sodium content in urine every day. And supplement it according to the lost amount.

Accordingly, there is no need to overemphasize protein intake. Otherwise, it may aggravate the condition of malnutrition. For them, changes the bad eating habits is important.
