Cereal brans and other ingredients added for health benefits such as fecal bulk and colonic fermentation typically impair expansion and mouthfeel of puffed cereal products. Resistant starches can be used in the manufacture of snacks and breakfast cereals without compromising product appearance, texture or palatability.135 Such resistant starches, offered for use in expanded cereals and snacks, use high-amylose... 

The digestibility of starch depends on source, physical condition, and food preparation. With the exception of lignin, dietary fibers may be partially or fully hydrolyzed by enzymes of the microflora present In the colon, iJome products arc absorbed into the bloodstream, but most serve as energy sources for the colono-cy tes. Specific dietary fibers can influence fecal bulk, the rate of passage of material through the intestines, and certain maladies such as constipation. 

Bulk-Forming Bulk-forming laxatives have natural fiber that absorbs water into the intestine, increasing fecal bulk and peristalsis, which results in large soft stools between 8 hours and 3 days. 

Bulk-forming laxatives are natural fibrous substances that promote large, soft stools by absorbing water into the intestines and increasing fecal bulk and peristalsis. Bulk-forming laxatives are non-absorbable. Defecation usually occurs within 8 to 24 hours but can take up to 3 days after the start of therapy for the stool to become soft and formed. 

Several mechanisms have been proposed for the protective action of the dietary hber found in whole grains. Increased fecal bulk and decreased transit time allow less opportunity for fecal mutagens to interact with the intestinal epithelium. Secondary bile acids are thought to promote cell proliferation, thus allowing increased opportunity for mutations to occur and abnormal cells to multiply. The effect of fiber on the actions of bile adds may be attributable to the binding or diluting of bile adds.

Considerable investigation has been reported on the effects of increasing dietary fiber on utilization of various minerals. Fiber supplementation may dilute the concentration of minerals by increasing fecal bulk, may lessen the absorption by decreasing fecal transit time, may encourage absorption of minerals upon fiber residues or trap minerals within residues, and/or may complex with phytate and other Inhibitors of mineral utilization. However, results of studies investigating utilization of different minerals under conditions of additions of different levels and sources of fiber have in no way been conclusive (26-29). 

The spectrum of the constituent sugars is characteristic for various types of plant NSP and may indicate the origin of the NSP measured. The values for wholemeal wheat products are characterized by high levels of insoluble NSP in the form of cellulose (measured as insoluble NSP glucose) and arab-inoxylans. Wholemeal wheat NSP are fermented slowly and incompletely, and exert a considerable effect on fecal bulk. White bread contains only 30% as much NSP as wholemeal bread, and this NSP is...

Fecal characteristics like a low bulk, high pH and a high concentration of (secondary) bile acids observed in correlation studies, are also related to a high incidence of colonic cancer[4-7] For this reason we studied the effects on fecal bulk, defecation frequency, fecal pH and fecal bile acids of diets with different amounts and types of animal protein. The diets were chosen not only on account of differences in origin of protein, but also in order to provide customary diets containing meat, plant foods and milk-based products (lactovegetarian) or plant foods only (vegan).

The beneficial effects of dietary fiber on the alimentary tract were emphasized by another of the founders of the dietary fiber hypothesis, Denis Bur-kitt, who based his arguments largely on the concept of fecal bulk, developed as a result of field...
