One of the most important advances in our knowledge of human health is the discovery and understanding of the microbiome. The microbiome is a community of healthy bacteria, viruses, archaea, and eukaryotic microbes that live on our skin and inside our body. Given its role in our immune and nervous systems, our skin, and every other major bodily system, you should expect this body of research to continue to balloon in the coming years.
However, one thing has already become apparent: Our lifestyle is a big contributor to the health of our microbiome. And everything we do—from the food we eat to the amount of sleep we get—affects the health of the microbiome almost immediately. Sadly, many of our diets are suboptimal, and we are exposed to an increasing amount of stress in our daily lives.
