Soil and gut are distinct ecosystems with striking functional parallels: both depend on diverse communities that transform nutrients, regulate boundaries and support resilience.
Parallel microbial worlds
Healthy soils and healthy intestines host complex communities of bacteria, fungi, viruses and other organisms. In both, diversity and functional cooperation help cycle nutrients and resist disruption.
Pathways of contact
Microbes and microbial products reach us through food, direct contact, animals, water and air. The significance of each pathway varies, and simplistic claims that eating soil will repair the gut should be avoided.
Rebuilding diversity
Fibre-rich diverse foods, fermented foods where suitable, appropriate outdoor contact and careful antibiotic stewardship may support microbial resilience. Regenerative farming can also improve soil biological function.
