All humans host a community of at least 38,000,000,000,000 microorganisms that lives on us and in us. This community, the microbiome, performs very critical functions like digesting food, managing inflammation, boost immune system and produce important vitamins, neurotransmitters and metabolites. Modern life style, poor diet, antibiotics, tobacco, sugar, stress, decreased breastfeeding, alcohol and many other environmental factors, have depleted the diversity and richness of most people’s microbiome.
