The effect of micronized corn fiber on body weight, glycemia, and lipid metabolism in rats fed cafeteria diet

Abstract During corn industrial dry milling, a residue rich in dietary fibers is generated. This study aimed to evaluate the effects of micronized corn fiber (MCF) as part of a cafeteria diet in the macronutrient metabolism and body weight. Wistar male rats, with initial body weight of 249 ± 14 g (n = 13), received AIN-93M diet (Group 1) or cafeteria diet (Groups 2, 3 and 4), composed of commercial ration, cookies, fried potato sticks, milk chocolate, bacon and chicken liver pâté. Groups 3 and 4 received MCF to replace 100 and 50% of the cellulose from the AIN-93M diet, respectively. After 35 days, blood, tissues and feces were collected. Data were analyzed by ANOVA followed by Tukey test (p

摘要
玉米工业干法研磨过程中，会产生富含膳食纤维的加工残渣。本研究旨在探究微细化玉米纤维（micronized corn fiber, MCF）作为自助日粮（cafeteria diet）组成部分，对宏营养素代谢与体重的影响。选取初始体重为249±14g的雄性Wistar大鼠共13只，分为4组：第1组饲喂AIN-93M日粮，第2、3、4组饲喂由商业配合饲料、曲奇、炸土豆条、牛奶巧克力、培根及鸡肝酱构成的自助日粮。第3组与第4组分别以MCF替代AIN-93M日粮中100%与50%的纤维素。饲养35天后，采集血液、组织及粪便样本。数据采用单因素方差分析（ANOVA）结合Tukey检验进行分析，以p
