There are many beneficial effects of increased dietary fibre consumption on human health and body function (Dreher, 2001). Dietary fibre can belong to the following categories: (i) edible carbohydrate polymers naturally occurring in the food as consumed; (ii) carbohydrate polymers, which have been obtained from food raw material by physical, enzymic or chemical means and which have been PI3K inhibitor shown to have a physiological effect of benefit to health as demonstrated by generally accepted scientific evidence to competent authorities; and (iii) synthetic carbohydrate
polymers which have been shown to have a physiological effect of benefit to health as demonstrated by generally accepted scientific evidence to competent authorities (Phillips & Cui, 2011). Traditionally, consumers have chosen foods such as whole grains, fruits and vegetables as sources of dietary fibre. Recently, food manufacturers have responded to consumer demands for foods with higher fibre content by developing products in which high-fibre ingredients are used (Nelson, 2001). Focus on the development of
tasty, health-promoting food options that are rich in cereal grains and fibres are needed to adequately offer the benefits of fibre to consumers (McCleary, 2011). Wheat is the most important cereal crop in the world and wheat bran (WB) is the major by-product selleck chemicals llc of the wheat industry
(Manisseri & Gudipati, 2010). The bran amounts to approximately 12–15% of the grain. Many benefits are associated to the consumption of WB, such Histone demethylase as reducing the risk of certain types of cancer; promoting positive health effects on the gastrointestinal tract, decreasing intestinal transit time and increasing fecal bulk and stool number; preventing and treating constipation; treating diverticulosis and irritable bowel syndrome; reducing the risk for obesity and assisting in weight maintenance; protecting against gallstone formation; and affording significant benefits to diabetics, by improving glycemic control and reducing the requirements for insulin and/or oral hypoglycemic agents (Cho & Clark, 2001). The portion of starch and starch products that resists digestion in the small intestine has been described as resistant starch (RS). Starch may become resistant to digestion due to several reasons, as it may be physically inaccessible (RS1), compact granular structure (RS2), retrograded or crystalline non-granular (RS3), chemically modified or re-polymerized (RS4) or amylose-lipid complexed (RS5) starches. RS may be categorized as a functional dietary fibre, as defined by the American Association of Cereal Chemists and Food and Nutrition Board of the Institute of Medicine of the National Academics (Fuentes-Zaragoza et al., 2011; Sharma, Yadav, & Ritika, 2008).
