Wheat fiber is a laxative and wheat protein may affect blood lipids.
We therefore tested the effects on laxation and serum lipid metabolism of a novel source of wheat fiber and protein produced by the amylolytic digestion of starch from wheat.
Twenty-four healthy men and women consumed 3 different test cereals in random order, each for 2 wk. The test supplement and the positive control, American Association of Cereal Chemists wheat bran supplement, both provided the same amount of fiber (21 g/d) and the negative control supplement provided 1.7 g fiber/d.
The test supplement and the positive control supplement increased fecal bulk similarly (239.5+/-19 and 216.7+/-19 g/d, respectively) and significantly more than did the negative control supplement (165.6+/-16 g/d, P < 0.010). Compared with the negative and positive control supplements, the week 2 value of the test supplement for the ratio of total to HDL cholesterol was significantly reduced (P = 0.046).
We conclude that the product of amylolytic digestion of starch from wheat flakes, which is high in wheat fiber and protein, has a fecal bulking effect similar to that of wheat bran and may have a beneficial effect on serum lipids.
小麦纤维是一种泻药，小麦蛋白可能会影响血脂。
因此，我们测试了一种由小麦淀粉经淀粉酶消化产生的新型小麦纤维和蛋白质来源对通便和血清脂质代谢的影响。
24名健康男性和女性随机食用3种不同的测试谷物，每种食用2周。测试补充剂和阳性对照（美国谷物化学家协会小麦麸皮补充剂）提供相同量的纤维（21克/天），阴性对照补充剂提供1.7克纤维/天。
测试补充剂和阳性对照补充剂使粪便量增加的情况相似（分别为239.5±19和216.7±19克/天），且显著高于阴性对照补充剂（165.6±16克/天，P<0.010）。与阴性和阳性对照补充剂相比，测试补充剂在第2周时总胆固醇与高密度脂蛋白胆固醇的比值显著降低（P = 0.046）。
我们得出结论，由小麦片淀粉经淀粉酶消化产生的产品富含小麦纤维和蛋白质，其粪便膨松效果与麦麸相似，可能对血清脂质有有益影响。
