Abstract
Probiotic products highly affect the health of consumers by reducing the risk of heart
attacks and improving the desirable microflora in the intestinal tract. In this study the
effect of yogurt (500g/d for 3 wk) enriched with either Bifidobacterium bifidum or
Lactobacillus acidophilus on the level of cholesterol, Low Density Lipoprotein (LDL) and
High Density Lipoprotein (HDL) of serum and as well on the intestinal microflora were
investigated in 24 healthy volunteers. Statistical analysis indicated that lower levels of
cholesterol and HDL were found after consumption of either one of bio-yogurts as
compared to the control states (P<0.05), whereas changes of LDL were not significant.
Also, in comparison with control periods the results of microbial counts indicated that the
number of fecal coliforms excreted during the consumption of either one of the yogurt
types were not noticeable, while the number of Bifidobacterium bifidum and Lactobacillus
acidophilus increased significantly (P<0.05).
