Abstract：
Red palm oil, a natural repository abundant in tocotrienols, tocopherols and carotenoids, is frequently employed as a pigment and nutritional enhancer in food products. The principal aim of this study is to explore the disparities in vitamin A levels, fatty acid profiles and gut microbiota among healthy adults who consume carotenoid-enriched eggs compared to those who consume normal eggs. A total of 200 hens were randomly assigned to either the red palm oil group or the soybean oil group, with the objective of producing carotenoid-enriched eggs and normal eggs. Throughout a six-month, double-blinded, randomized controlled trial, participants were instructed to consume one carotenoid-enriched or normal egg daily at a fixed time. Fecal and blood samples were collected from the participants at the start and conclusion of the six-month intervention period for further analysis. Our findings indicated that there was no significant change in the vitamin A level for daily supplementation with one carotenoid-enriched egg, but there were significant changes in some indicators of fatty acid profiles and gut microbiota compared to the control group of the population. Nonetheless, the consumption of eggs, regardless of carotenoid-enriched eggs or normal eggs, positively influenced dietary habits by reducing the intake of saturated fatty acids and enhancing the intake of monounsaturated and polyunsaturated fatty acids of the population.
摘要：
红棕榈油,一个富含生育三烯酚的天然储存库，生育酚和类胡萝卜素，经常用作食品中的色素和营养增强剂。这项研究的主要目的是探索维生素A水平的差异，与食用正常鸡蛋的人相比，食用富含类胡萝卜素的鸡蛋的健康成年人的脂肪酸谱和肠道微生物群。共有200只母鸡被随机分配到红棕榈油组或大豆油组，目的是生产富含类胡萝卜素的鸡蛋和正常鸡蛋。在六个月的时间里，双盲,随机对照试验,参与者被指示在固定的时间每天食用一个富含类胡萝卜素的鸡蛋或正常的鸡蛋.在6个月干预期的开始和结束时从参与者收集粪便和血液样本用于进一步分析。我们的发现表明，每天补充一个富含类胡萝卜素的鸡蛋的维生素A水平没有显着变化，但与人群对照组相比，脂肪酸谱和肠道菌群的一些指标有显著变化。尽管如此，鸡蛋的消费，无论富含类胡萝卜素的鸡蛋还是普通鸡蛋，通过减少饱和脂肪酸的摄入量和增加人群单不饱和脂肪酸和多不饱和脂肪酸的摄入量，对饮食习惯产生积极影响。
