Scientists and medical professionals are now spending more time than ever studying our bodies’ microbiome: a delicate balance of the approximately 100 trillion fungi and bacteria that live in our gut. The body’s microbiome affects nearly every single system in our bodies, playing a role in metabolism, immunity, and even neurobiology. In fact, the microbiome is considered so important to understand that the multi-million dollar Human Microbiome Project was developed in order to study the correlation between various strands of bacteria and the diseases that they may affect.
