This module ready for piloting.

Bacteria are everywhere -- even on the food we eat. Sometimes, we want to avoid microbes to prevent illness, and even take medication to kill them. Other times, these microbial communities can actually work to boost human health. For thousands of years, people intentionally added microbes to their food for a variety of reasons, such as for flavor and preservation. Morerecently it has been discovered that ingesting certain strains of bacteria can help alleviate symptoms of certain diseases. By studying the microbiomes of different types of food, we can see what we are consuming in a whole new light.
