There is strong evidence that eating food that is high in fiber (commonly referred to as roughage) is associated with a lower risk of heart disease, stroke, type 2 diabetes, and bowel cancer.
The fiber found in foods (dietary fiber) is a form of carbohydrate that cannot be digested or broken down into sugars. The fiber in foods can either be water-soluble or insoluble. Examples of water-soluble fiber are pectins, beta-glucans, resistant starches, and gums. Examples of insoluble fiber are cellulose, hemicellulose, and lignin.
Water-soluble fiber has benefits in reducing blood lipid levels (total cholesterol and LDL-C). It also reduces insulin resistance. Insoluble fiber aids digestion and encourages bowel movement.
Fiber is found in foods such as fruits and vegetables, whole grains, seeds, and nuts.
There are two main types of fiber found in foods. These are soluble and insoluble fibers.
Choosing foods with a high fiber content also makes us feel fuller. This is very helpful for losing or managing weight.
The recommended daily allowances (RDAs) for total fiber for people aged 19-50 years is 38 grams/day for men and 25gram/day for women. Very few people eat up to this amount.
