The Effects of TwoLactobacillus plantarumStrains on Rat Lipid Metabolism Receiving a High Fat Diet
The aim of our study was to evaluate the effects of the different probiotic strains,Lactobacillus plantarumLS/07 andLactobacillus plantarumBiocenol LP96, on lipid metabolism and body weight in rats fed a high fat diet. Compared with the high fat diet group, the results showed thatLactobacillus plantarumLS/07 reduced serum cholesterol and LDL cholesterol, butLactobacillus plantarumBiocenol LP96 decreased triglycerides and VLDL, while there was no change in the serum HDL level and liver lipids. Both probiotic strains lowered total bile acids in serum. Our strains have no significant change in body weight, gain weight, and body fat. These findings indicate that the effect of lactobacilli on lipid metabolism may differ among strains and that theLactobacillus plantarumLS/07 andLactobacillus plantarumBiocenol LP96 can be used to improve lipid profile and can contribute to a healthier bowel microbial balance.
