The digestive system processes foods taken into the body and breaks it down to its useable components – carbohydrates, proteins, fats, vitamins and minerals. It also expels waste from the body. A diet with plenty of dietary fibre and water is essential to keep the digestive system functioning well. Running a poor digestive system for extended periods of time reduces overall nutritional intake leading to a multitude of other problems and can also cause cancers of the digestive system.
Fibre is found in whole grains, vegetables and fruit – essential to healthy gastrointestinal function. Leading health organisations recommend adults to consume 30-40 grams of dietary fibre per day, which is about 5-9 portions of fruits and vegetables. For urban populations, this is often not feasible and this is where supplements can assist.
Applied nutrition
It is often necessary to explore whether it is the intake of food or lack thereof that is the source of the problem. If the diet and lifestyle is changed for a particular condition but problems persist, then it may be useful to direct attention to the digestive system.
Chew food properly. Eat slower if you are a fast eater. Turn off all distractions when eating – this includes the TV, the phone and speaking too much. Avoid cold liquids and excess liquids when eating meals. Heat improves digestion generally.
Like a pipeline, you’ll need water. 8 glasses (250ml) is a good guideline, to be sipped throughout the day from morning to 7pm and not in large gulps.
