The chemical element arsenic exists in eels. Generally, the content is very small, but the increasingly serious environmental pollution may make the arsenic content in these animals reach a higher level. Generally speaking, pentavalent arsenic is harmless to human body.
Theoretically, high dose of vitamin C (taking vitamin (vitamin food) C more than 500 mg at a time) and pentavalent arsenic will be converted into toxic trivalent arsenic (commonly known as "arsenic") through complex chemical reactions, and trivalent arsenic can cause human poisoning when it reaches a certain dose.
If you eat a lot of eels and drink beer at the same time, it will accelerate the formation of uric acid in the body.

Eel has the most balanced nutrition, and various nutrients are widely distributed, especially the nutrients necessary for human body and lacking in ordinary food, which are the most abundant in eel. The vitamins A, B, B and B of eel are 9 times, 30 times, 3 times and 38 times that of milk, respectively. Zinc is five times as much as milk. People compare eels to "ginseng in water, a treasure house of vitamins", which makes sense.
Eel skin and meat contain a lot of collagen, and the beauty beauty effect of taking eel collagen is unmatched by any cosmetics. Eels can really be called edible cosmetics. This is also one of the reasons why eels are "in power" in Japanese and Korean cuisine.
