You and Your Microbiome


The pursuit of happiness is a fundamental human goal. Today – the international day of happiness – is celebrated throughout the world. But should we only celibate human happiness? What about all our micro-organism? Most of the cells in the human body aren’t even human. In fact, bacterial cells outnumber human cells 10 to 1. One hundred trillion bacteria cram inside you. Scoop them up and they would weigh about a kilogram. Linked end-to-end, they would circle the globe two and a half times. If aliens were to look at us from outer space, liquified some humans, in order to define what species we where, they would think we were bacteria. Just to give you an idea.

Not all bad guys

Although we normally talk about all the bad microbes, the ones we carry around are not all evil. In fact, humans would not exist without the help of our microbial inhabitants. Bacteria are crucial facilitators of many of our basic bodily functions: from digesting food and producing vitamins to fending off harmful infection and recovering from illness. When it comes to getting and staying healthy, balancing our intestinal microflora should be a top priority.

So today, while celebrating international happynessday – pay some attention to your own and your families microbiome. (not a bad idea for other days either)
