The human intestinal tract is home to a diverse and complex microbial community that is increasingly being recognized for its importance in overall human health. This community is commonly referred to as a hidden metabolic 'organ' due to its pivotal impact on a vast array of functions including metabolism, physiology, nutrition and immunity. Thus, alterations of the microbiome can significantly impact health and thus contribute to multiple chronic disease states. In this presentation, Dr. Robert Rountree in this video discusses the role of the microbiome in health and disease - including practical ways to restore and maintain a healthy microbiome.
