The Effects of Mediterranean Diet on the Human Gut Microbiota; a Brief Discussion of Evidence in Humans
The Mediterranean diet (MD) is considered one of the healthiest dietary patterns due to its rich provision of phytochemicals, antioxidants, vitamins, fiber, polyunsaturated, omega-3, and short-chain fatty acids through a variety of foods. The supply of such nutrients and bioactive components can support gut health and reduce systemic inflammation, with accumulating evidence from several human studies demonstrating the utility of the Mediterranean diet in the prevention of chronic and metabolic diseases. Further studies are needed to explore the role of the Mediterranean diet protecting against such diseases and the related mechanisms, including the interplay between components of the MD and gut microbiota. This brief systematic review specifically explores the recent evidence in humans investigating the link between MD and the human microbiota. Herein, over 50 articles were revised and referenced, after a careful vetting process, to produce this manuscript. Articles were ultimately selected based upon the detail and novelty of their content and contribution to the field.
