How Differences in the Composition of Microorganisms in the Soil Affect the Microorganisms in the Human Gut, Through the Vegetables That Grow in it: a Process Pilot Study With Healthy Participants

Sponsor: Leiden University Medical Center

Summary

There are two objectives for this clinical trial. The first is to test whether, with the current logistics and study setup it is possible to perform the study well and see where there might be bottlenecks we couldn't predict. The second objective is to investigate the relation between the composition of the microorganisms in the soil, the crops that grow in that soil, and the human gut. During the study participants will drink three vegetable smoothies a day, for two periods of one week. The only difference between the two periods is whether the vegetables come from a farm with a low diversity of microorganisms in the soil or a high diversity. Participants will be asked to give blood samples and turn in fecal samples before and after each period.
