“Nutrition and the gut microbiome” at the Microbes and Social Equity virtual symposium, June 15, 2021

The Microbes and Social Equity working group and The University of Maine Institute of Medicine present an inaugural symposium on:

“Microbes, Social Equity, and Rural Health”

June 14 – 18th, 2021

Format: virtual meeting, Zoom platform.

Day 1 of the Microbes and Social Equity virtual symposium

Session 2: “Nutrition and the gut microbiome”

Tuesday, June 15th, 13:00 ~ 16:00 EST.  Registration for this session is closed.

Session leader: Laura Grieneisen

Access to fresh foods, and especially fruits, vegetables, and other products high in fiber, is well demonstrated to be affected by social inequity.  The lack of fiber and nutritious food can dramatically hamper a functional gut microbiome.  With the effects of COVID-19 being felt, the loss of income/loss of SNAP benefits and disruption to our food and transport systems will make it more difficult for many individuals to obtain a nutritious diet and reap the benefit of a healthy gut microbiome. This effect will be disproportionately felt by lower-income individuals. This session explores the effects of diet on the gut microbiome and health, food insecurity, policy to support food access, and how to use existing resources to create community-based food systems.

Program and Registration

A full speaker list and program, and details of each day can be found here.

Registration will occur for each (day) section individually, so participants can select which topics to participate in, or all of them. 

Registration is free and open to the public.


Microorganisms are critical to many aspects of biological life, including human health.  The human body is a veritable universe for microorganisms: some pass through but once, some are frequent tourists, and some spend their entire existence in the confines of our body tissues.  The collective microbial community, our microbiome, can be impacted by the details of our lifestyle, including diet, hygiene, health status, and more, but many are driven by social, economic, medical, or political constraints that restrict available choices that may impact our health.   

Many human clinical conditions or diseases have been established as being related  to the state of the human microbiome.  It is known that collective social inequity can drive the prevalence, morbidity, and mortality of some of these diseases or conditions. When access to a nutritious  diet and healthcare are impeded by social inequity, these disparities can also affect the human microbiome; this can further contribute to reduced or poorly functioning microbiomes. 

Access to resources is the basis for creating and resolving social equity—access to healthcare, healthy foods, a suitable living environment, and to beneficial microorganisms, but also access to personal and occupational protection to avoid exposure to infectious disease. The emergence of the SARS-CoV2 (COVID-19) pandemic has dramatically altered our daily lives and the availability and ability to access essential resources, which has been worsened by pre-existing social inequity. Yet, the pandemic has also highlighted the inherent social disparity among those more likely to be exposed to infectious diseases.  

This meeting highlights recent investigations into beneficial and detrimental instances of microbial exposure, in the context of how social policy may mediate or deepen disparities between and within populations. In addition to invited presentations on thematic sections, each section will involve a discussion session using smaller breakout groups, to facilitate conversations and brainstorming between attendees.  These groups will be arranged around smaller themes or research questions, and group members will identify knowledge gaps for future research, as well as list actionable steps that can be taken using existing research to promote equitable social policy.  Ideally, meeting attendees will gain knowledge, collaborators and connections, and a path forward for turning their research into evidence-based policy to support public health.

Meeting dynamics

Unlike traditional symposium formats, this meeting will present some plenary-style talks by experts in the field, including biological scientists, social scientists, practitioners or policy makers, as well as facilitate discussion among participants. Each thematic section will feature 90 minutes of talks, which will be recorded and made publicly available after the live session.  After each plenary session, there will be 90 minutes of discussion in groups led by speakers and MSE group members, and assisted by notetakers, with ~10 participants per breakout room. Participants will be encouraged to “problem solve” a suggested topic or one of their own choosing.  The goal is to create action items that are meaningful for group participants, such as ideas for curricula development, identifying research needs or best practices, suggestions for engaging research in policy, and more.
