This study aimed to compare the nutritive value and obesity prevention of ordinary (CM) and selenium-enriched CM (SeCM). The results indicated that Se enrichment significantly increased the total carbohydrate and soluble dietary fiber content, while the protein and insoluble dietary fiber content decreased. Although the fat content was not affected, the medium and long-chain fatty acids content significantly changed. Moreover, Se enrichment significantly elevated the secondary metabolites belonging to terpenoids and alkaloids, which are linked with the enhanced biosynthesis of secondary metabolites. Both CM and SeCM reduced body weight, adipose accumulation, impaired glucose tolerance, and lipid levels in high-fat diet (HFD)-fed mice, and there was no significant difference between them. Network pharmacological analysis revealed that dietary CM and SeCM prevented HFD-induced obesity and associated metabolic diseases with multi-ingredients acting on multi-targets. Overall, Se enrichment improved the nutritive value of CM without altering its role in preventing obesity.
本研究旨在比较普通玉米(CM)和富硒玉米(SeCM)的营养价值及预防肥胖的效果。结果表明,富硒显著增加了总碳水化合物和可溶性膳食纤维含量,而蛋白质和不溶性膳食纤维含量降低。虽然脂肪含量未受影响,但中长链脂肪酸含量显著变化。此外,富硒显著提高了属于萜类和生物碱类的次生代谢产物含量,这与次生代谢产物生物合成增强有关。CM和SeCM均能降低高脂饮食(HFD)喂养小鼠的体重、脂肪堆积、葡萄糖耐量受损及血脂水平,二者之间无显著差异。网络药理学分析表明,食用CM和SeCM可通过多种成分作用于多个靶点来预防HFD诱导的肥胖及相关代谢疾病。总体而言,富硒提高了CM的营养价值,同时未改变其预防肥胖的作用。
