| Aims: This trial aims to determine the effects of resistant
starch (RS) subtype 2 (RS2) on glycemic status, metabolic endotoxemia
and markers of oxidative stress. Methods: A randomized,
controlled, parallel-group clinical trial group of 56
females with type 2 diabetes mellitus (T2DM) was divided to
2 groups. The intervention group (n = 28) and control group
(n = 28) received 10 g/day RS2 or placebo for 8 weeks, respectively.
Fasting blood samples were taken to determine
glycemic status, endotoxin, high sensitivity C-reactive protein
(hs-CRP), malondialdehyde (MDA), total antioxidant capacity
(TAC), antioxidant enzymes concentrations as well as
uric acid at baseline and after the intervention. Results: After
8 weeks, RS2 caused a significant decrease in the levels ofMDA (–34.10%), glycosylated hemoglobin (–9.40%), insulin
(–29.36%), homeostasis model of insulin resistance (–32.85%)
and endotoxin (–25.00%), a significant increase in TAC
(18.10%) and glutathione peroxidase (11.60%) as compared
with control. No significant changes were observed in fasting
plasma glucose, quantitative insulin sensitivity check index,
hs-CRP, superoxide dismutase, catalase and uric acid in
the RS2 group as compared with the control group. Conclusion:
Supplementation with RS2 may be improved glycemic
status, endotoxemia and markers of oxidative stress in patients
with T2DM. |
