Objective: To determine the effects of ω-3 polyunsaturated fatty acids from different sources on glucolipid metabolism in type 2 diabetic patients with dyslipidemia. Methods: We recruited participants from the diabetes specialist clinic at the Guanlin hospital in Yixing city, Jiangsu Province from February 2017 to March 2017. A total of 180 subjects were randomly assigned to 3 g/day fish oil (FO), perilla oil (PO), or fish oil mixed with linseed oil (FLO) for 6 months. The basic conditions and fasting venous blood sample were obtained from each study subject at baseline, after 6 months of intervention. Serum glucose and lipid metabolism were investigated. Results: A total of 156 subjects aged (62.6±8.6) years completed the final follow-up after 6 months (FO,54 subjects; PO,52 subjects; FLO,50 subjects). Among them,59 patients (37.8%) were male. Serum glucose, glycated hemoglobin, C peptide, insulin and homeostasis model assessment-insulin resistance were not significantly different among the three groups after 6 months. Serum triglyceride decreased, whereas high-density lipoprotein cholesterol increased in FO [1.33 (1.05,1.93) mmol/L, (1.36±0.29) mmol/L, respectively] compared with PO [1.71 (1.23, 2.17) mmol/L, (1.23±0.22) mmol/L, respectively] and FLO [1.51 (1.12, 2.22) mmol/L, (1.29±0.30) mmol/L, respectively] (P<0.05). Serum low-density lipoprotein cholesterol and apolipoprotein B decreased in PO [(2.60±0.57) mmol/L,(0.96±0.23) g/L, respectively] compared with FO [(2.89±0.76) mmol/L, (1.07±0.30) g/L, respectively] (P<0.05). Serum lipoprotein(a) decreased in FLO [130.7 (63.3,270.6) mg/L] compared with FO [137.4 (58.7,333.2) mg/L] (P<0.05). Serum free fatty acid decreased in FLO [(0.43±0.15) mmol/L] compared with PO [(0.53±0.22) mmol/L] (P<0.05). Conclusion: The effects of ω-3 PUFA from different sources on glucose metabolism in type 2 diabetic patients with dyslipidemia are similar. Each of them has a good application prospect in improving lipid metabolism.
