Have you ever heard the saying, “You are who you surround yourself with?” Well, it turns out there might be more truth to that than you thought! A recent study took a deep dive into the world of microbiomes and discovered something pretty amazing – your gut and oral bacteria (AKA your microbiome) can be heavily influenced by the people you live and interact with.

Think about it, have you ever shared a drink with a friend or shared a kiss with a partner? It turns out that these little interactions can actually transfer bacteria between people, changing the makeup of their microbiomes. In fact, the study found that mothers and infants had the highest rate of microbiome sharing, but as we grow older, other relationships can have an impact too.

So, next time you’re considering who to spend your time with, think about the impact it could have on your health! Your gut bacteria could be the key to staying healthy, and it all starts with who you surround yourself with. Let’s spread the love – and the bacteria! – to our friends and family and keep each other healthy.
