The additional effects of a probiotic mix on abdominal adiposity and antioxidant Status: A double-blind, randomized trial.

To investigate whether a probiotic mix has additional effects when compared with an isolated dietary intervention on the body composition, lipid profile, endotoxemia, inflammation, and antioxidant profile. Women who had excess weight or obesity were recruited to a randomized, double-blind trial and received a probiotic mix (Lactobacillus acidophilus and casei; Lactococcus lactis; Bifidobacterium bifidum and lactis; 2 × 10 In comparison with the dietary intervention group, the dietary intervention + probiotic mix group showed a greater reduction in the waist circumference (-3.40% vs. -5.48%, P = 0.03), waist-height ratio (-3.27% vs. -5.00%, P = 0.02), conicity index (-2.43% vs. -4.09% P = 0.03), and plasma polyunsaturated fatty acids (5.65% vs. -18.63%, P = 0.04) and an increase in the activity of glutathione peroxidase (-16.67% vs. 15.62%, P < 0.01). Supplementation of a probiotic mix reduced abdominal adiposity and increased antioxidant enzyme activity in a more effective way than an isolated dietary intervention.
