Aim: This study aimed to evaluate the effect of supplementation with ground flaxseed (GF) on the concentrations of adiponectin, resistin, and visfatin in patients with ulcerative colitis (UC). Background: Inflammatory bowel disease (IBD) is one of the most common gastrointestinal diseases affecting people of all ages. Adipokines secreted from adipose tissue have been shown to play an essential role in the pathogenesis of UC. Methods: This trial is an open-labeled randomized controlled trial conducted on 70 patients with UC. The patients were randomly divided into two groups: flaxseed and control. The patients in the intervention received 30 g/day flaxseed powder for 12 weeks. Patients' anthropometric, nutritional, and biochemical factors were evaluated at the beginning and end of the intervention period. Results: Totally, 64 patients (36 men and 28 women) with a mean age of 31.12±9.67 were included in the final analysis. There was no significant difference between the two groups regarding baseline weight and height (P>0.05). After the 12-week intervention, flaxseed supplementation led to a significant reduction in the resistin (-4.85±1.89 vs. -1.10±2.25, P<0.001) and visfatin concentration (-1.33±1.14 vs. -0.53±1.63, P=0.018). Further, we found a significant increase in the adiponectin levels after the GF supplementation (3.49±1.29 vs. -0.35±0.96, P<0.001). Conclusion: Flaxseed supplementation could exert beneficial effects on adipokine levels in patients with UC.
