Understand your inner workings
Digestion is the process which breaks down the all the food and liquids we eat into nutrients. It happens in our digestive tract – although most nutrient absorption occurs in the small intestine.
The food which isn’t digested or absorbed during digestion becomes waste. This waste includes fibre – it escapes the digestive enzymes in the small intestine andand moves into the large intestine. This is where water is absorbed and fibre and resistant starches are broken down by bacteria, producing fatty acids and gas.
Increasing your fibre intake doesn’t necessarily increase your wind – simply boost your fibre intake slowly and be sure to drink more fluids.
How long it takes to digest a meal
The digestive tract (or alimentary canal) tends to be 9-10 metres long. It takes around 12-48 hours for food to be digested and the waste material (stools or faeces) to be expelled from the body.
