Definition & Types
Fiber is defined differently throughout the world. Definitions can be made depending on the analytical methods for isolating the fiber. However, there is a move to define fiber on a physiological basis. In the past, dietary fiber was classified based on its solubility into two categories, soluble and insoluble fiber. Soluble fibers were considered to have benefits on serum lipids, while insoluble fibers were known for their laxative benefits. The scientific evidence supporting this classification is inconsistent as there are some fibers (e.g. resistant starch and inulin) which do not follow the same rule. Currently, the use is relying on the analytical approach to classify fibers. With this approach the fiber is classified into; dietary fiber, which is non-digestible carbohydrates and lignin that are intrinsic and intact in plants, and functional fiber, which consists of the isolated, non-digestible carbohydrates that have beneficial physiological effects in humans.
How much fiber do we need?
According to the Institute of Medicine, women and men need 25g and 38g of fiber, respectively, per day. However, the average adult only eats around 15g of fiber per day.(6) So, how can we fill the gap?
One way of doing so, is by eating more vegetables, fruits, beans, whole grains and nuts. In general, the intake of whole foods is the best way to get fiber because they also provide the body with the required nutrients.(6)
However, the intake of the required amount of fiber per day needs good planning and careful selection of foods. Since our products (Prebio-Tayebt & Prebio-Manna) contain over 85% of the soluble indigestible dietary fiber (prebiotic), they can be taken as a part of your everyday diet. Adding these products to your diet will help you reach the amount of fiber you need to eat per day and hence, obtain the health benefits that we all need.
