A preponderance of carcinogenesis studies in rodents and epidemiologic studies in humans suggests a potential role of dietary fiber in the prevention of colorectal cancer. Recently, wheat bran fiber used as a dietary supplement has been shown to decrease the growth of rectal adenomatous polyps in patients with familial polyposis; however, few studies of high-risk human populations have been att...

Fermentation of polysaccharides in the colon seems likely to regulate tumorigenesis but the mechanisms are unclear. A possible mechanism may be through facilitation of the acute apoptotic response to genotoxin-induced DNA damage. This study evaluated the effects of selected dietary polysaccharides, resistant starch (supplied as Hi-maize) and nonstarch polysaccharides (supplied as wheat bran and...

Grains of the wheat variety Tajan were milled into straight-run flour and bran. Proximate analysis, farinograph experiments and rheological characteristics were conducted. Two types of bran (hydrothermal treated and untreated) at three levels (0%, 5%, 10%) were added to the parent flour. Proximate analysis and farinograph experiments of these flours were conducted. The effects of adding treated...

HIGHLIGHTS The dephytinized wheat bran reduced the specific volume of bread samples compared with bran. hardness and chewiness values were increased, springiness cohesiveness decreased raise in rate storage. Sensory analysis revealed that addition or up to 5% was acceptable.

INTRODUCTION wheat bran has been known for many health benefits, but its glucose- and lipid-lowering activity still remains unresolved. OBJECTIVE to investigate effects of varying amounts of wheat bran and feeding period on serum glucose and lipids in sucrose-fed rats. METHODS eighty male Sprague-Dawley rats were assigned into 4 sucrose-based diets containing either 0, 5, 10 or 20% wheat br...

BACKGROUND Pretreatments are a prerequisite for enzymatic hydrolysis of biomass and production of ethanol. They are considered to open up the plant cell wall structure by altering, moving or solubilizing lignin and hydrolyzing a proportion of hemicellulosic moieties. However, there is little information concerning pretreatment-induced changes on wheat bran cell wall polymers and indeed on chang...

Bulk in the distal colon provides protection against a range of large bowel disorders, but a simple standardized measure of the relative bulking efficacy of foods, for use in dietary management of distal colonic bulk, has not been available. This paper describes a faecal bulking index (FBI) for standardized measurement of the relative colonic bulking efficacy of foods relative to a reference ma...

Effects of the use of 200 g of either wheat bran, sugar beet pulp, soya bean hulls or alfalfa meal per kilogram diet on the digestive process of the weaned piglet were studied on 24 Duroc Landrace male piglets, weaned at 28 days of age. Piglets had an initial mean live weight of 7.92( 1.1) kg and were randomly distributed in six successive blocks of four animals. The total tract apparent digest...

1. Four groups of adult male Sprague-Dawley rats were fed for 6 weeks on a diet with a low-fat content (50 g/kg) and another four groups were given a diet rich in fat (250 g/kg) and cholesterol (12 g/kg). In both cases, the basal diets were either fibre-depleted or supplemented with cellulose (60 g/kg), wheat bran (100 g/kg) or low-methoxyl pectin (100 g/kg). 2. Low-methoxyl pectin displayed th...
