​​​​Gut Microbiome​​

Each new year we read about commitments to health and wellness, with both personal messages and media reporting on improving health outcomes. In keeping with this New Year tradition, our newest Food for Thought topic is the Gut Microbiome.

The gut microbiome consists of trillions of microorganisms that live in human and animal digestive tracts. These organisms are essential to the health of their hosts, with research showing they can affect everything from body weight to mental wellbeing.

The Cereals & Grains Association has collected years of research that explores the science behind the impact of cereals and grains on digestive health, and the role they play in this dense and varied microbial system. We have curated these resources that display impactful research related to the gut microbiome.
