Abstract
The increase in stool weight after feeding 20 g (dry weight) of bran daily was measured when this was of large particle size and after milling to small particle size. Twenty-eight investigations were carried out in 21 normal subjects. With coarse bran, stool weight was significantly greater than with the fine bran (mean 219.4 g/d coarse bran, 199-0 g/d fine bran: difference 20.4 g SE +/-6.4, P less than 00.1). The coarse bran also had a greater water-holding capacity (7.3 g water/g coarse bran, 3.9 water/g fine bran). Coarse bran was 2 1/2 times the volume of fine gran for a given weight and more fine bran will, therefore, be taken when bran is prescribed by the spoonful.
摘要
每天喂食20克（干重）麸皮后，分别测量大颗粒麸皮和磨成小颗粒麸皮后的粪便重量增加情况。对21名正常受试者进行了28项研究。食用粗麸皮时的粪便重量显著高于细麸皮（粗麸皮平均每天219.4克，细麸皮每天199.0克：差值20.4克，标准误±6.4，P<0.01）。粗麸皮的持水能力也更强（粗麸皮每克含7.3克水，细麸皮每克含3.9克水）。对于给定重量，粗麸皮的体积是细颗粒麸皮的2.5倍，因此，当按勺服用麸皮时，会摄入更多的细麸皮。
