Objective To investigate the effect of nutrition intervention based on low glycemic index (GI) foods on blood glucose in patients soon after renal transplantion. Methods 100 renal transplantion patients were enrolled, whose incidence of glycometabolism disorder was analyzed. Patients with glycometabolism disorder were randomly divided into two equal groups. One group was given low glycemic index foods while the other was given free foods as control. The duration of treatment for both groups was 30 days. Changes in fasting blood glucose and 2 h plasma glucose in patients were observed. Results The incidence of glycometabolism disorder was 54%，and the disorder occurred 15 days to 180 days after renal transplantion. After low glycemic index food intervention, fasting blood glucose and 2 h plasma glucose in the treatment group decreased significantly ( P ＜0.01), much unlike control group ( P ＜0.01). Conclusions Nutrition intervention based on low GI foods helps alleviate glycometabolism disorder soon after renal transplantion．
