Background: This research aimed to study the effect of coriander seed supplementation on serum glycemic indices, lipid profile and oxidative stress parameters in patients with type 2 diabetes mellitus (T2DM).
Methods: In this randomized double-blinded, placebo-controlled trial, eligible 40 T2DM patients aged 30-60 years were recruited from Sina Hospital (Tabriz, Iran) and randomly assigned into two groups to receive either coriander seed powder (1000 mg/day, n=20) or placebo (1000 mg/day, n=20) for 6 weeks. Anthropometric measurements, dietary intake, and biochemical parameters including fasting blood sugar (FBS), serum insulin, Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), total cholesterol (TC), triglyceride (TG), high- and low-density lipoprotein cholesterols (HDL-C and LDL-C), malondialdehyde (MDA), and total antioxidant capacity (TAC) were assessed before and after supplementation.
Results: Anthropometric measurements were not significantly different between intervention and placebo groups. Coriander seed supplementation led to significant within-group reductions in FBS (156.15±23.19 to 130.30±21.15), serum insulin (17.72±0.47 to 17.12±0.76), HOMA-IR (6.82±0.95 to 5.52±0.99), TC (183.85±55.68 to 145.20±31.36), TG (152.50±37.59 to 130.40 ±27.96), LDL-C (127.35±23.45 to 111.40±25.71), and MDA (1.65±0.15 to 1.49±0.15), whereas there were significant increases observed in serum TAC (1.93±0.12 to 1.97±0.09) (P<0.05). Post-dose comparisons showed significant between-group differences for FBS, serum insulin, HOMA-IR, TC, TG, LDL-C, MDA, and TAC levels after adjusting for baseline values (P<0.05).
Conclusions: Coriander seed supplementation was able to improve glycemic indices, lipid profile and oxidative stress status in T2DM and it may be useful complementary treatment in management of these patients.
Trial registration: The study protocol was registered on the Iranian Registry of Clinical Trials website (IRCT20190224042821N2) on 2019/Oct/11.
