Don't expect probiotic benefit from yogurt

Probiotic yogurt increases the presence of certain probiotic strains, but does not change the overall microbiota makeup, according to research in the journal PharmaNutrition. Volunteers were told to eat either commercial probiotic yogurts or a placebo daily for four weeks. Fecal sample analysis showed no difference in profile variation between the placebo and probiotic yogurt consumption. The finding supports earlier research which found that probiotic yogurt did not modify the composition of gut microbial communities.
