Actually Ty, consuming even your own feces is dangerous. About 1/3 of our poop is made of water, about 1/3 of it is made up of dead bacteria- an assortment of microcorpses that come from the microorganisms that assist us in the digestion of food. The final third of our crap consists of undigestable foods (corn kernels, cellulose, etc)- known as fiber.
In fact, diseases such as food poisoning, chlorea, and typhus among others are spread from fecal contamination. Parasites such as tapeworm are also spread through the consuption of shit.
"There are some parasites, such as pinworms, who depend on people eating their own poop to keep the population up. Pinworms are small nematodes that live in the colon. The females emerge from the anus at night to lay their eggs. Their activity makes the anal area itch. The person scratches the itch (often doing so in his sleep), procuring a small amount of fecal matter and eggs under his fingernails, and then puts his fingers in his mouth. Once the eggs are consumed, the person is infected with a new generation of pinworms." - ??
