Summary

Children were exposed to biodiverse material or non-diverse material in sand pits. The two arms were compared. Immune response and bacterial markers were followed.

Detailed description

Children of age 3-5 were randomly divided into two groups (arms). One received guidance and biodiverse material for 20 minutes each day for two weeks. The other received the a similar material and guidance but the microbial community in the material was poor in diversity. Bacterial community changes and immune system markers were analyzed and compared between the two arms. Potential changes in Interleukin 10 was the primary outcome.
