Zinc (Zn) is an essential trace element required for human beings and animals. This divalent cation is involved in many physiological functions, including immune and antioxidant function, growth, and reproduction. Deficiency of Zn produces several pathological disorders and abnormalities in its metabolism, such as anorexia, weight loss, poor efficiency, and growth retardation. Although it has been known for more than 50 yr that Zn deficiency regularly and consistently causes anorexia in many animal species, the mechanism that causes this phenomenon still remains an enigma. The present review describes recent research investigating the relationship between Zn deficiency and the regulation of food intake, as well as macronutrient selection.
锌（Zn）是人类和动物必需的微量元素。这种二价阳离子参与许多生理功能，包括免疫和抗氧化功能、生长和繁殖。锌缺乏会导致多种病理紊乱及其代谢异常，如厌食、体重减轻、效率低下和生长发育迟缓。尽管50多年来人们已经知道锌缺乏在许多动物物种中经常且持续地导致厌食，但导致这种现象的机制仍然是个谜。本综述描述了最近关于锌缺乏与食物摄入调节以及常量营养素选择之间关系的研究。
