From a nutritional point of view, internal organs have many benefits to the human body.
The internal organs are rich in iron.
Excluding the pale white belly and intestine of animals, most of the internal organs are crimson in color, especially the liver, kidney, heart and spleen.
Anyone who knows a little nutrition knows that eating crimson animal viscera, such as liver, can help people with iron deficiency anemia to supplement iron. Because the purplish red color of viscera is brought by [heme].
[Heme] It is the reason why the viscera, muscles and blood are red. Its molecules contain iron. The viscera is dark and thick because it contains more heme than the iron content in meat, and the absorption and utilization rate of iron in it is very high.
For example, when adding supplementary foods to older infants, As long as you add a spoonful of liver mud, you can effectively supply iron and prevent the common iron deficiency anemia in infants. In addition to pig liver, chicken liver, duck liver, foie liver and sheep liver are also as good, duck gizzard, chicken heart and pig kidney (kidney) are also good, as long as it is crimson internal organs, all have the effect of helping to supplement iron, but liver is easier to make mud.
The viscera is rich in vitamins.
People also know that the liver can help some people improve their eye health, because the vitamin A content in animal liver is extremely high, far exceeding other foods such as milk, eggs, meat and fish, which can effectively prevent and treat eye diseases such as night blindness, dry eye and keratomalacia.
In fact, the nutritional value of the liver does not stop there. In animals, the liver is the base camp of nutrient reserves. It contains all 13 vitamins needed by the human body, of which vitamin A, vitamin D, vitamin B2 and vitamin B12 are especially high.
The protein content of liver exceeds that of lean pork. Iron, zinc, copper, manganese and other trace elements are very rich, which is almost the most complete and abundant food in nature. Wild carnivores never give up this important source of nutrition and always eat the liver together after predation.
In addition to the liver, the kidney of animals also contains a lot of vitamin A and vitamin D, while the content of vitamin D in ordinary meat is very low. In terms of the content of various B vitamins and trace elements, the kidney, heart and gizzard of poultry are significantly higher than that in ordinary meat. In other words, they are [red meat] with higher nutrient content.
