Future work should address the mechanisms by which ingestion
of nondigestible carbohydrates improves mineral absorption.
Another group
of nondigestible carbohydrates that may affect mineral absorption are native resistant and retrograded resistant starches.
Based on the panelâ $ ™ s deliberations, consideration of public comments, and subsequent modifications, the following definitions have been developed: Dietary Fiber consists
of nondigestible carbohydrates and lignin that are intrinsic and intact in plants.
The women consumed 0 grams, 10 grams or 20 grams
of this nondigestible carbohydrate each day for 50 days.
The relative importance of the mechanisms may vary with the type and amount
of nondigestible carbohydrate and of the mineral in the diet.
Says Perea, «FOS is a type
of nondigestible carbohydrate, and it produces fatty acids that provide energy to the large intestinal mucosal (dog mucous membrane).
Not exact matches
Dietary fiber is a
nondigestible form
of carbohydrate that has no effect on blood sugar levels when it is consumed.
TABLE 7 - 1 Characteristics
of Dietary Fiber Characteristic Dietary Fiber

carbohydrate No
Carbohydrates not recovered by alcohol precipitationa Yes
Nondigestible mono - and disaccharides and polyols No Lignin Yes Resistant starch Some Intact, naturally occurring food source only Yes Resistant to human enzymes Yes Specifies physiological effect No a Includes inulin, oligosaccharides (3â $ «10 degrees
of polymerization), fructans, poly - dextrose, methylcellulose, resistant maltodextrins, and other related compounds.
Functional Fiber consists
of isolated,
nondigestible carbohydrates that have beneficial physiological effects in humans.
This two - pronged approach to define edible,
nondigestible carbohydrates recognizes the diversity
of carbohydrates in the human food supply that are not digested: plant cell wall and storage
carbohydrates that predomi - nate in foods,
carbohydrates contributed by animal foods, and isolated and low molecular weight
carbohydrates that occur naturally or have been synthesized or otherwise manufactured.
Distinguishing Features
of Dietary Fiber Compared with Functional Fiber Dietary Fiber consists
of nondigestible food plant
carbohydrates and lignin in which the plant matrix is largely intact.
Rationale for Definitions
Nondigestible carbohydrates are frequently isolated to concentrate a desirable attribute
of the mixture from which it was extracted.
Nondigestible plant
carbohydrates in foods are usually a mixture
of polysaccharides that are integral components
of the plant cell wall or intercellular structure.
