Is human feces brown in colour?
Feces are fascinating. Our body is a world of energy efficiency and unparalleled waste management. If machines and industries ran as well as our intestines and colon, we could say goodbye to landfills. The complex digestion process ensures that almost no useful energy goes unused. The average bowel movement is three parts water to one part solid matter. Bacteria make up 30% of the solid stuff. The same goes for indigestible foods like cellulose and fibre.
The remaining 40% contains various inorganic wastes, fats and used-up body substances like red blood cells, which are released from the liver in an orange-brown compound called bilirubin. Bilirubin mixes with another liver product, yellowish bile, to give poop its distinctive hue. TNN
