With the antimicrobial properties of honey being further established, I fielded an interesting question the other day about whether or not nature's gold would inhibit probiotics.  It turns out that honey actually seems to work as a pre-biotic, a food-source for both lactobacillus and bifidobacterium.  Both of these natural flora in the GI tract are found in the guts of vaginally born, breast fed infants and have the best correlation with a healthy immune system.  Here are three articles I was sent for further reading:
