Food Biome to Human Biome: Beyond Nutrients

A collaboration with the ASN Nutritional Microbiology Research Interest Section


Gut microbiota is intertwined with host metabolism, immune function, and psychological state. Foods we consume are one of the main drivers to shift microbiota profile and functionalities. Thus, data in the literature have been mainly focusing on elucidating complex relationships between host, gut microbiota, and unabsorbed nutrients. Nevertheless, microbes residing on or in foods are anticipated to have an impact on the gut microbiota profile and functionalities. For example, the health benefits of bacteria and related metabolites in fermented foods, e.g. yogurt, cheese or kimchi have been reported. Fresh produce can present another source of direct human exposure to microbes. Thus, microbes of non-fermented foods should be included in the paradigm of gut microbiota, foods, and host health. In this symposium, experts will discuss the microbes of food sources, gut microbiota, and health implications. The goal of understanding the food biome is to help define healthy, functional gut microbiota.
