Applications of mixed starch as staple food in nutritional management in patients with chronic kidney diseases

Objective To discuss the application of mixed starch as staple food innutritional management in patients with chronic kidney diseases (CKD). Methods A total of 80 CKD patients diagnosed with CKD phase 1~4 in Yibin No. 2 People's hospital and Yibin No. 2 TCM Hospital from January 2017 to June 2018 were selected and divided into the control group and the mixed starch group randomly. Those patients in the control group received traditional health education according to low protein diet, while the patients in the mixed starch group were fed with the mixed starch as staple food made up of sweet potato starch, potato starch and wheat starch on the basis of low protein diet. Finally, the indexes of nutritional status, renal function and subjective feelings of patients were observed after 3 months of intervention. Results After intervention,body weight, body mass index, hemoglobin, albumin, nutritional status, serum creatinine, creatinine clearance rate and urea nitrogen level in the mixed starch group were all superior to those in the control group(P<0.05). There were no significant differences of subjective experience including taste acceptance, satiety, nausea and vomiting between 2 groups (P>0.05). Conclusions Mixed starch as staple food may reduce intake of non-high-quality protein, improve nutritional status and renal functions of patients, and can be used as a preferential option for staple food in out-hospital nutrition management of CKD patients.
