Food should benefit your body, it is its essence and the main task. Unfortunately, this is not always the case. Often even the most useful products are in the stop-list. This also applies to fish, which has always been considered useful, and not vice versa.

Fish refers to one of the healthiest and proper foods that people should eat. However, some fish contain plenty of mercury, which is not healthy for humans to consume. The fact is, the human body is not able to get rid of this metal, and this can lead to bad consequences. Below you will find a list of 9 types of fish that are better to avoid. So, read and take notes!

This type of fish has a high level of mercury contamination. As we all know mercury is not healthy for humans to consume. So, it is not recommended to eat tilefish.

#8. Oilfish

Oilfish (white tuna) has gempylotoxin, a substance that is similar to wax and gives the meat an oily taste. The fact is, this substance is not digested by the human body, so it can lead to bad digestion. However, this type of fish isn't very toxic, so you should fry or grill to reduce the amount of gempylotoxin.
