The elderly generally require around 20-35 grams of fiber per day. However, in those suffering from constipation, the fiber intake should be increased to between 25-60 grams a day. A diet high in fiber will help add waste and weight to feces, while fiber also absorbs water which can make the fecal matter softer. This allows it to move through the digestive system more simply, making bowel movements easier.
The elderly often suffer from weak teeth, or a lack of teeth altogether. This can make chewing food quite difficult, thus causing indigestion. Moreover, fibrous foods usually come in the form of green vegetables and fruits which tend to be sticky and difficult to chew properly. Preparing food so it is softer and also easier to chew, digest and swallow, is therefore of huge importance to the elderly. This type of food preparation may take many forms, such as cutting, mincing or blending food, so that it is in small pieces before it is steamed, stewed or boiled to make it even softer.
