To our knowledge, no reports are available indicating the effects of synbiotic food consumption on blood lipid profiles and biomarkers of oxidative stress among pregnant women. This study was conducted to evaluate the effects of daily consumption of a synbiotic food on blood lipid profiles and biomarkers of oxidative stress in pregnant women. This randomized, double-blind, controlled clinical trial was performed among 52 primigravida pregnant women, aged 18 to 35-year-old at their third trimester. After a 2-week run-in period, subjects were randomly assigned to consume either a synbiotic (n = 26) or control food (n = 26) for 9 weeks. The synbiotic food consisted of a probiotic viable and heat-resistant Lactobacillus sporogenes (1 × 10⁷ CFU) and 0.04 g inulin (HPX)/g as the prebiotic. Patients were asked to consume the synbiotic and control foods two times a day. Biochemical measurements including blood lipid profiles, plasma total antioxidant capacity (TAC) and total glutathione (GSH) were conducted before and after 9 weeks of intervention. Consumption of a synbiotic food for 9 weeks resulted in a significant reduction in serum TAG (P = 0.04), VLDL (P = 0.04) and a significant rise in plasma GSH levels (P = 0.004) compared to the control food. No significant effects of the synbiotic food consumption on serum TC, LDL, HDL and plasma TAC levels (P > 0.05) were observed. Trial registry code: http://www.irct.ir . IRCT201212105623N3.

Background:This research was to examine the effects of synbiotic intake on minerals, liver enzymes, and blood pressure in patients with type 2 diabetes (T2D).Methods:This randomized, cross-over clinical trial was performed among 62 diabetic patients. Persons were randomly assigned to intake either a synbiotic (n = 62) or a control food (n = 62) for 6 weeks. A 3-week washout period was applied following which persons were crossed over to the alternate intervention arm for an additional 6 weeks. The synbiotic was consisted of Lactobacillus sporogenes (1 × 107 CFU), 0.04 g inulin (HPX) as prebiotic. Persons were asked to consume the synbiotic and control foods 27 g a day. Blood pressure was measured, and blood samples were taken at baseline and after 6-week intervention to assess calcium, magnesium, iron, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, and total bilirubin.Results:The consumption of a synbiotic food, compared to the control food, resulted in a significant rise of calcium (0.66 vs. −0.14 mg/dL, P = 0.03) and iron (5.06 vs. −9.98 mg/dL, P = 0.03). The decrease of total bilirubin (0.08 vs. −0.04 mg/dL; P = 0.009) was also seen in the synbiotic group compared with the control group.Conclusions:Overall, synbiotic in T2D patients had beneficial effects on calcium, iron, and total bilirubin concentrations.
