In this episode, I break down what is meant by prebiotics, probiotics and postbiotics. We are an ecosystem. The microbiome reveals a more connected biology and it is evolving our approach to medicine, hygiene, diet and lifestyle. Our bacteria are our gatekeepers to the outside world. When we ingest food, it's still actually in an external environment. The bacteria that reside within the colon are sitting on the epithelial surface in a mucous membrane and they digest our food, regulate inflammation, synthesize key vitamins, metabolites and neurotransmitters.
