Abstract
The aim of this study was to determine the effect of fermented and non fermented skim milk on blood lipid profile and blood sugar in Sprague-Dawley rats as a model. Rats fed on 1% cholesterol diet, two probiotics were used (L. acidophilus and B. bifidum). Results showed a significant increase in diet conversion efficiency for groups fed on fermented milk with B. bifidum and those fed on B. bifidum and L. acidophilus compared with control group. A slight decrease in total cholesterol (TC) was noticed in most groups, the best treatment was fermented L. acidophilus mixed with B. bifidum. In addition a significant decrease) P<0.05) was found in triglycerides (TG) in the same group. A significant increase in high density lipoprotein (HDL) in L. acidophilus with fermentation and B. bifidum with fermentation. Liver glycogen showed a significant increase in rats fed on fermented B. bifidum and L. acidophilus. Muscle glycogen showed a significant increase in all groups except for L. acidophilus with out fermentation. It is concluded that the mentioned diets play a positive role to improve lipid profile of rats and increase muscle glycogen. Non significant changes were found in blood glucose in all groups.
