Can the dirt under our feet shape the bacteria in our gut?

This pilot study asks whether the diversity of microbes in soil can influence the bacteria living in the human gut. Ten healthy adults will drink vegetable smoothies made from crops grown in either low- or high-microbial diversity soil for one week each. Researchers will check if live bacteria from the smoothies appear in stool samples and whether the gut microbiome changes. The main goal is to test whether the study procedures work smoothly before a larger investigation.
