Is eating fish raw harmful to your health?

it's best not to eat raw fish. Because there are often parasites in fish, if you eat raw fish often, it is inevitable that you will not be infected with these parasites. Some places have the custom of eating raw fish gall, which is said to cure some diseases. They don't know that fish bile contains a toxic substance-"bile toxin". Whether eaten raw, cooked or served with wine, it may cause toxic effects on human body. Traditional Chinese medicine uses fish bile to treat diseases, and the dosage is very small, generally only 1.5 ~ 4 grams, so you can't take too much. Coastal people also have a habit of eating shark liver, but eating too much can also cause poisoning. This is because shark liver is rich in vitamin A. Excessive intake of vitamin A in the human body can also cause poisoning. Some people dare to take risks to eat puffer fish, which is highly toxic. If it is not treated seriously, it will really kill you after eating it.
