Eel is a kind of edible fish, and their nutritional value is relatively high, which contains more protein, but also contains a lot of trace elements, minerals and various vitamins and so on. However, when eating, we should pay attention to the fact that eels are poisonous and belong to a kind of blood poison. That is to say, their flesh and blood can not be eaten raw, because their flesh and blood are poisonous at this time. They, as long as they are cooked, they will be fine and can be safely eaten.
In addition, it should be noted that if the eel died of illness, it is best not to eat it. The main reason is not that they are poisonous, but that their bodies may have been invaded by pathogens, which may be harmful to human body if eaten. Generally speaking, within a few hours after the eel died, the bacteria had multiplied. Moreover, after a period of time after death, histidine in eels may decompose to produce histamine, which is toxic. Therefore, if you encounter eels that die for unknown reasons, you can't eat them easily.
As mentioned above, eels are poisonous. However, their toxicity belongs to blood toxicity, but can not be eaten raw, after cooking, it will be fine. In fact, the nutritional value of eel is still very high, suitable for eating, can play a role in enriching the blood. It is also important to note that the toxic substance histamine, which has been mentioned above, is produced after a period of time after the death of eels, and this toxin may cause dizziness, headache or a drop in blood pressure.
