It is important what types of food you eat. Fibre rich foods such as fresh vegetables or fresh fruit can help prevent us from conditions such as constipation or from having bowel problems, and that is because these types of foods will break down quicker in your digestive system and let your body eliminate the waste that it does not need.
It can usually take anywhere up to 72 hours for the remains of foods to pass through your system. It is much easier to pass through your system if you eat foods such as whole grain bread, cereal, all types of fresh fruit or green vegetables such as beans or peas.
If you tend to eat low fiber foods such as sugary foods or white flour, these can stay in your intestines longer because they take longer to digest.
It is always best to eat food regularly. It is not good for you to keep eating small amounts of food at short intervals. Try to eat larger amounts at regular intervals, and it is recommended that about three to four hours between meals is probably about the right amount of time.
This would be dependent on what type of food you eat and obviously how much you eat.
The human body also needs to rest before and after meals, probably a ten minute rest before food and thirty minutes after a meal is considered to be all that is needed.
It is normally recommended that you have one main meal per day; this would normally be around 12 o clock.
