Nutrient deficiencies and excess are involved in many aspects of human health. As a source of essential nutrients, eggs have been used worldwide to support the nutritional needs of human societies. On the other hand, eggs also contain a significant amount of cholesterol, a lipid molecule that has been associated with the development of cardiovascular diseases. Whether the increase of egg consumption will lead to elevated cholesterol absorption and disruption of cholesterol homeostasis has been a concern of debate for a while. Cholesterol homeostasis is regulated through its dietary intake, endogenous biosynthesis, utilization, and excretion. Recently, some research interests have been paid to the effects of egg consumption on cholesterol homeostasis through the intestinal cholesterol absorption. Nutrient components in eggs such as phospholipids may contribute to this process. The goals of this review are to summarize the recent progress in this area and to discuss some potential benefits of egg consumption.
营养缺乏和过剩涉及人类健康的许多方面。作为必需营养素的来源，鸡蛋在全球范围内被用于满足人类社会的营养需求。另一方面，鸡蛋也含有大量胆固醇，这种脂质分子与心血管疾病的发展有关。鸡蛋摄入量的增加是否会导致胆固醇吸收增加和胆固醇稳态的破坏，一段时间以来一直是争论的焦点。胆固醇稳态通过其饮食摄入、内源性生物合成、利用和排泄来调节。最近，一些研究关注了通过肠道胆固醇吸收，食用鸡蛋对胆固醇稳态的影响。鸡蛋中的营养成分如磷脂可能有助于这一过程。本综述的目的是总结该领域的最新进展，并讨论食用鸡蛋的一些潜在益处。
