Physiological implications of wheat and oat dietary fiber.

摘要: The physiological implications of various types dietary fiber (DF) are highly correlated to the chemical and structural composition cell wall materials (CWM) (e.g. Anderson Chen, 1979; Eastwood Kay, Cummings Branch 1982; Selvendran, 1984; Wisker et al. 1985). These factors in turn determine physical physicochemical properties DF which water holding capacity, viscosity cationic exchange capacity have attracted most interest (Van Soest Robertson, 1976; 1979). Wheat bran has a high proportion insoluble lignified CWM (Selvendran, 1984) behaves more or less like inert marker gastrointestinal (GI) tract. little no effect on digestion absorption nutrients small intestine is resistant microbial degradation large monogastrics including man (Stephen Cummings, 1980). Consequently wheat bran, due its presence, one efficient sources increasing fecal bulk decreasing mouth-to-anus transit time (Cummings 1978; Spiller 1986).
