American Society for Nutrition Annual Meeting
Virtual, USA
June 4, 2020
10:30 am – 12:00 pm

This meeting has been shifted to virtual by the ASN Board of Directors due to the COVID-19 pandemic.

The session below “Food Biome to Human Biome: Beyond Nutrients” will be shifted to Nutrition 2021, to be held in Boston, MA. 

The below sessions are organized by ILSI North America’s Gut Microbiome Committee in collaboration with the American Society for Nutrition’s Microbiology Research Interest Group.

Toward Best Practices for Nutrition and Human Gut Microbiome Research: Moving the Field Forward

This session examines best practices across critical steps in nutrition and human gut microbiome research. As noted in McBurney et al. 2019, study of the human gut microbiome “requires proper sample acquisition, handling, storage and analysis.” Accurate characterization of diet and minimization of technical variation are critical for establishing links between diet and the gut microbiome and health. Achieving an understanding of the effect of diet requires that gut microbiome studies include detailed dietary data to elucidate the impact of the amount and types of dietary non-digestible carbohydrates, polyphenols, alcohol use, and water quality on the microbiome. In addition to characterization of diet, harmonizing research methodologies will be required if the body of research on the human gut microbiome is to be examined collectively to answer critical public health and nutrition questions.

Co-Chairs and Moderators: Cindy Davis, National Institutes of Health and Chris Cifelli, National Dairy Council

Food Biome to Human Biome: Beyond Nutrients — Due to changes in the Nutrition 2020 platform, this session will be shifted to Nutrition 2021, to be held in Boston, MA.

Gut microbiota is intertwined with host metabolism, immune function, and psychological state. Foods we consume are one of the main drivers in shifting microbiota profile and functionalities. Thus, data in the literature have been primarily focused 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 source, gut microbiota and health implications. The goal of understanding the food biome is to help define healthy, functional gut microbiota.
