Do you investigate your stool before you flush? If not, you should start! Your poo is a printout of your current health. The stool is made up of different kinds of secretions; the color of it generally depends on what food we eat. The transverse colon contains only waste products and no more nutrient absorption occurs beyond this point. The amount of debris, composition, color and odor of feces depends on whether the frequency of the food and water taken in is low or high, meaning dead or alive.
