Do you think the microorganisms in the large intestine have any other role other than producing odour in the faeces ? If yes, then what role do they have?
• Break down undigested food.
• Neutralise some of the harmful by-products of food breakdown.
• Aid the absorption of nutrients.
• Produce certain vitamins such as Vitamin K, needed for blood clotting.
• Make life uncomfortable for harmful bacteria by competing for food and controlling levels of oxygen and acidity in the gut so that the living conditions favour beneficial species.
• Because the majority of the immune system is located in your gut, beneficial bacteria also help support the body’s natural defences.
