Abstract
This study aims to determine the effects of fenugreek seed dry extract (FDE) on the glycemic indices, lipid profile, and prooxidant-antioxidant balance (PAB) in patients with type 2 diabetes (T2D). A double-blind randomized clinical trial was carried out on 54 individuals with T2D. Participants were randomly assigned to a FDE group (received 3 tablets containing 335 mg of FDE daily for 8 weeks) or a placebo group (received tablets containing microcrystalline cellulose). Anthropometric indices, physical activity, diet, fasting blood sugar (FBS), serum insulin, Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), triglyceride (TG), total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein (HDL-C), and PAB were assessed. An eight-week intake of 3 tablets containing 335 mg of FDE decreased serum insulin (P=0.016, P<0.001), HOMA-IR (P=0.009, P<0.001), TG (P<0.001, P=0.001), and PAB (P<0.001, P<0.001) compared to the baseline, in both placebo and intervention groups respectively. TC decreased significantly compared to the baseline in the placebo group (P=0.028), while HDL-C increased in the FDE group compared to the baseline (P<0.001) and placebo group (P=0.014). In the present study even though changes of parameters were more in intervention group compared to the control group, we did not observe any significant differences between studied groups except for HDL-C. However, the effects might become apparent with a higher dosage, longer study duration, or a larger sample size compared to the placebo group. Further clinical trials are needed in this regard.
