In the world of wild animals, all eating is to save strength for the next meal. It is better to eat the softest part than to work hard on the muscles and tendons. It is not shameful for the tiger, leopard and jackal to eat soft rice. After all, eating soft rice is the easiest way to eat more food, and animals will evolve when there are other carnivores beside it. In the process of continuous hunting, animals will gradually develop the habit of eating perishable places, that is, internal organs, and then eating slow-decaying places and body parts, so that they can eat for a longer period of time. This is also a reasonable food distribution model.
Animal liver is the main organ for animals to metabolize and store nutrients. It is rich in protein, vitamins (such as vitamin A, vitamin D and vitamin B) and trace elements (such as iron and zinc). Regular consumption of animal liver can also supplement vitamin B2, which plays an important role in supplementing the important coenzyme of the body and completing the detoxification of some toxic components. The liver also contains vitamin C and trace element selenium, which are not contained in common meat food, which can enhance the immune response of human body, resist oxidation, prevent aging and inhibit the generation of tumor cells.
Viscera is rich in iron, which is the most common food in blood-enriching foods, especially pig liver, whose nutritional content is more than ten times that of pork, which can adjust and improve the physiological function of hematopoietic system of anemia patients, and the vitamin content is also relatively high. The vitamin A content in animal liver is much higher than that in eggs, milk, fish, shrimp and lean meat. One of the most important functions of vitamin A is to maintain eye health, which can effectively prevent and treat eye diseases such as night blindness and dry eye.
