The effect of resistant starch RS4 on apparent absorption of magnesium and iron was studied in Wistar rats. The rats (4 groups male n=12 and 4 groups female n=12) were fed for 4 weeks diets: control with wheat starch (K) and 3 diets with modified resistant starches (S1, S2, S3). After an adaptation period (14 d), rats were transferred to metabolic cages. Dietary intake and faeces were monitored for 3 days. Mg and Fe levels were assessed in diets and feces by atomic absorption spectrometry. Apparent absorption of minerals was calculated as mineral intake minus fecal excretion and expressed as persentage of intake. Our results confirmed that Mg apparent absorption in female rats fed diet with resistant starch S2 was significantly increased (+37%) compared with the control group.
在Wistar大鼠中研究了抗性淀粉RS4对镁和铁表观吸收的影响。将大鼠(4组雄性,每组n = 12;4组雌性,每组n = 12)喂食4周不同饮食:含小麦淀粉的对照组(K)和3种含改性抗性淀粉的饮食(S1、S2、S3)。在适应期(14天)后,将大鼠转移到代谢笼中。监测3天的饮食摄入量和粪便量。通过原子吸收光谱法评估饮食和粪便中的镁和铁水平。矿物质的表观吸收量通过矿物质摄入量减去粪便排泄量计算得出,并以摄入量的百分比表示。我们的结果证实,与对照组相比,喂食含抗性淀粉S2饮食的雌性大鼠的镁表观吸收量显著增加(+37%)。
