The effects of hot air-dried white button mushroom powder on glycemic indices, lipid profile, inflammatory biomarkers and total antioxidant capacity in patients with type-2 diabetes mellitus: A randomized controlled trial.

BACKGROUND

The inflammatory and metabolic responses to mushroom in type 2 diabetes mellitus (T2DM) are unknown. The study aimed to evaluate the effect of Hot Air-dried White Button Mushroom (HAD-WBM) powder on glycemic status, lipid profile, inflammatory markers, and total antioxidant capacity (TAC) in T2DM patients.

MATERIALS AND METHODS

This randomized controlled trial was conducted at Golestan Hospital, Ahvaz, Iran. Eligible patients were adults aged 20-50 with Type 2 diabetes. Patients were assigned to each group using a randomized block design with block randomization ( = 22, in each group). Randomization was performed by an assistant and group allocation was blinded for the investigator and participants. The intervention and control groups received 16 g/day HAD-WBM or cornstarch powder for 8 weeks. The primary outcomes of interest were fructosamine, fasting blood sugar (FBS), insulin, homeostatic model assessment for insulin resistance, and secondary outcomes were triglyceride, low-density lipoprotein (LDL), high-density lipoprotein, very-LDL, cholesterol, high-sensitivity C-reactive protein (hs-CRP), interleukin 6 (IL-6), and TAC.

RESULTS

After 8 weeks, a significant decrease was observed in fructosamine (-0.228 ± 0.36 vs. 0.03 ± 0.38; = 0.02) and LDL (-13.05 ± 20.67 vs. 0.81 ± 21.79; = 0.04) in the HAD-WBM group compared to the control group. No significant changes were observed in fasting insulin and FBS between the two groups. However, a significant within-group reduction (-28.00 ± 42.46; = 0.006) was observed for FBS in the HAD-WBM group. In the HAD-WBM group, insulin resistance reduced significantly at the end of the study (From 4.92 to 3.81; = 0.016), but it was not significantly different between the two groups. There was no significant difference in TAC, hs-CRP, and IL-6 between the two groups.

CONCLUSION

Considering the results of this study about the beneficial effects of HAD-WBM on the improvement of glycemic indices and LDL in T2DM patients, it is recommended that HAD-WBM could be used to control T2DM.
