Why would people eat poo Brooke?
Your digestive system has about 10,000 different types of bacteria in it, and the distribution of these species has a major impact on the functioning of your body. This distribution is now thought to play a role in obesity, crohn's disease, colitis, diabetes, allergies, and various other autoimmune diseases. There is even evidence that it plays a role in autism. This is the burgeoning scientific field of the microbiome.
There are some medical conditions where a person's distribution of bacteria gets out of whack (c. difficile infection is a current well-known example, but this will likely expand to more things), and a solution is to recolonize the digestive tract with a more-usual mix of bacteria by a technique called a "fecal transplant", which is basically eating poo.
It is quite interesting. I suspect that it will become a gigantically larger field in biotech and health care in the very near future.
