Abstract
OBJECTIVE: Extrusion is a widely used food processing technology. The aim of this study was to investigate the effects of extruded adzuki bean convenient food (EABCF) on glycemic and inflammation control in type 2 diabetes mellitus (T2DM) patients. PATIENTS AND METHODS: In a randomized controlled trial, 120 T2DM patients were randomly assigned to a control diet group (the low glycemic index [LGI] group, assigned the traditional diabetic low glycemic index diet) or an intervention group (the EABCF group, assigned daily consumption of EABCF). Diet information and blood samples were collected at baseline and after a 4-week intervention. After excluding exogenous insulin users, a subgroup analysis based on baseline fasting insulin (FINS) levels was conducted, and Homeostasis Model Assessment (HOMA) was the target indicator. RESULTS: A total of 106 patients completed the trial, and 89 participants were included in the subgroup analysis. After the intervention, glycemic control improved in both groups compared to baseline, but the difference was not statistically significant (p>0.05). However, the EABCF group showed decreased inflammation with significantly lower tumor necrosis factor alpha (TNF-α) level compared to the control group (adjusted p<0.01). There was also a slight increase in the interleukin-6 (IL-6) level in the EABCF group (adjusted p=0.004). Moreover, the subgroup analysis found that, after 4 weeks, a diet consisting of EABCF increased insulin secretion to normal levels in the group with hypoinsulinism (baseline FINS<5.2 mU/L). However, the difference only showed a trend toward statistical significance (0.05
