It's just another reason to value the wisdom passed down to us from the classical Greeks, who recognized honey as a medicinal food over 2,000 years ago.

Bifidobacterium and Lactobacillus, two genera of microorganisms that are present in fermented milk products like yogurt, form one of the foundational parts of a healthy gut microbiome. Both kinds have been found to improve bowel function in all stages of digestion from breakdown to absorption to defecation.

It's never been more important to disseminate this information, since the honey-yogurt study reports that between 10 and 25% of the American population report unsatisfactory bowel function. In other words, for as many as one in every four people in the room, trips to the bathroom are miserable.

"As yogurt with honey is a common food pairing, and honey supports probiotic survival in vitro, we aimed to determine if this functional food combination would enhance probiotic abundance and improve functional outcomes in vivo," the authors write.

The study had a randomized, controlled, single-blind, crossover design with two 2-week intervention periods. Yogurt beverages were consumed twice daily during each intervention period, with one group consuming theirs with sugar, and the other with clover honey. There was nothing special about the yogurt, and it was in fact a pasteurized, name-brand product with natural vanilla flavoring.

While almost none of their study outcomes were met, it was clear from the results that the in vitro effect reported above carried over in vivo as there was a greater abundance of Bifidobacterium animalis in the stools of those who consumed yogurt with honey rather than just yogurt or yogurt with sugar.

The study also failed to produce evidence that yogurt with honey improved any digestive function, but the authors noted that most of the participants had predominantly normal bowel functions during the trial period, and they suggest that those with dysfunctional activity arising from constipation, IBS, or other complications should be included in future studies on the topic.
