In China, although many people don't eat animal offal, it doesn't rule them out of the food culture. Moreover, many famous dishes and home-cooked dishes are made of animal viscera, such as spicy fried pork intestines and hairy blood curd. However, in some countries, people don't eat animal offal since childhood. I have worked in Singapore for six years, and Singaporeans almost reject the internal organs of animals. Not only internal organs, such as duck's head and pigskin, are rarely eaten. Almost all these things are consumed by China people.

In China, the internal organs of animals are commonly called "entering the water", which sounds derogatory. There are three reasons: 1. Most internal organs of animals have unpleasant smells, which is why many people hate them. 2. Animal liver is an important metabolic organ in the body and an important detoxification organ. The metabolism of various nutrients in the human body should be carried out in the liver, including toxic substances and pollutants in food should be detoxified in the liver. It is inevitable that some poisons or pollutants will remain in the internal organs. 3. High cholesterol. It is true that animal visceral cholesterol is high. The cholesterol content of the liver of the same animal is 3-4 times that of the muscle. In addition, the content of saturated fatty acids in animal viscera is also high, and saturated fatty acids have been identified as the killer of cardiovascular diseases. These three reasons should also be the main reasons why many people don't like to eat animal offal.

People have always had two opinions about eating "animal offal". The positive opinion is that animal viscera is rich in nutrition, which can not only supplement iron, zinc and protein, but also improve eyesight and has medicinal value, so it should be eaten more; Counterview: I think it is unhealthy to feed industrial raw materials and ripen them with hormones. So, should animal viscera be eaten?

It is necessary to eat the internal organs of animals. Because the internal organs are indeed rich in trace elements such as iron and zinc, vitamin A, vitamin B 12, vitamin D and so on. People can effectively make up for the human body's demand for these substances after eating. For example, chicken gizzards and duck gizzards are very suitable, because they are rich in protein and chickens and ducks, but their fat is only one fifth of that of chickens and ducks. It can be said to be healthy food. Especially when the child is developing, it is more beneficial. For people who use their eyes too much, eating animal offal can also improve their eyesight, and the most common one is sheep liver.

Animal viscera is not only delicious food, but also helpful to treat some diseases. For example, eating pig heart often has a certain therapeutic effect on palpitation and insomnia patients; Niu Xin has therapeutic effect on belching and fright; Pig stomach can cure fatigue, strengthen spleen and stomach, tonify kidney and so on. And because these are all complementary foods, the side effects are minimal. Come on, center it

However, everything has two sides. Although the function of animal viscera is not small, it can't be eaten unscrupulously. Because of the existence of uncertain factors such as industrial feed feeding, hormone application and pesticide residues, normal people should not exceed 50 grams twice a week. The cholesterol content in animal viscera is also high. People with hyperlipidemia had better not eat it, and people with obesity had better not eat pig large intestine because of its high fat content.

I would like to remind all friends that the internal organs of fish are easy to be polluted and deteriorated, and are rich in harmful microorganisms. Don't eat them.
