Eels are divided into freshwater and seawater. There are about 19 species of freshwater eels in the world. They are similar in appearance. They grow up in rivers or freshwater and migrate to the sea only when they lay eggs. Academically speaking, eels refer to creatures within the Muraenesocidae family, but because the public often interprets them as "eels in the sea", the eels in our population have expanded from eels to fish that swim in the sea as long as they look long. But in fact, the eel family is not a narrowly recognized eel in academia.
Eel is rich in vitamin A and E, which are 60 and 9 times higher than that of common fish, respectively. Vitamin A is 100 times as much as beef and 300 times as much as pork. Rich vitamin A, vitamin E, for the prevention of visual deterioration, protection of the liver, restore energy has great benefits. Other vitamins such as vitamin B1 and vitamin B2 are also abundant. Eel meat is rich in high-quality protein and various essential amino acids for human body.
鳗鱼分为淡水和海水。世界上大约有19种淡水鳗鱼。它们的外观相似。它们生长在河流或淡水中，只有产卵后才移居大海。从学术上讲，鳗鱼是指Muraneocidae家族中的生物，但由于公众经常把它们解释为“海洋中的鳗鱼”，所以我们人类中的鳗鱼从鳗鱼扩展到了在海洋中游泳的鱼，只要它们看起来很长。但事实上，在学术界，鳗鱼家族并不是一个狭隘的认可鳗鱼。

鳗鱼富含维生素A和E，分别是普通鱼类的60和9倍。维生素A是牛肉的100倍，是猪肉的300倍。丰富的维生素A、维生素E，对预防视力恶化、保护肝脏、恢复精力有很大的好处。其他维生素如维生素b1和维生素b2也很丰富。鳗鱼肉富含优质蛋白质和人体必需的各种氨基酸。

人体摄入过量的维生素A可引起中毒综合征，称维生素A中毒症（Vitamin A toxicity）。最早报千于十六世纪九十年代，北极探险者食北极熊肝后数小时发生头痛、呕吐、嗜睡等症，因人及动物体内的维生素A90～95％贮于肝脏。近年国内由于滥用维生素A浓缩剂，产生中毒症状者不断增多，主要系因家长缺乏合理应用维生素A的知识，认为用量越多越好，医务人员亦缺乏警惕性，值得引起重视。据研究，婴幼儿服用维生素A，如一次剂量超过30万国际单位时(每克普通鱼肝油含维生素A850国际单位;每克浓鱼肝油含维生素A5-6.5万国际单位)，会引起急性中毒。如每天服用5万-10万国际单位，连续服用6个月左右，即可发生慢性中毒。此外，孩子对维生素A的敏感性和耐受程度可有较大的个体差异，有些孩子在服用鱼肝油未超出上述范围时，亦可出现轻度的中毒症状。
