Let's first look at the advantages and disadvantages of intestines. The intestines of most animals contain more nutrients than muscles, especially the liver, but at the same time, most intestines contain more fat and almost always more cholesterol than muscles. When it comes to toxic substances, it depends largely on where you buy food. If you buy meat from a bad vendor, whether it is viscera or not, it is rich in artificial hormones and heavy metals. Eating a small amount of food, 25-50g each time, half a piece or two, that is, 2-3 mouthfuls, can greatly avoid the health problems caused by excessive accumulation of heavy metals and other nutrients.
Liver is rich in vitamin A, vitamin D and vitamin B, as well as trace elements such as iron and zinc, which is a good source of nutritional supplement for patients with iron deficiency anemia and blindness. The heart is also rich in vitamin B, especially vitamin B 1, which has a good neurotrophic effect. Stomach, commonly known as stomach, such as pork belly, tripe, tripe, etc. Although there are not many outstanding nutritional advantages, the taste is excellent, and the fat and cholesterol content in the viscera is the lowest, so you can choose.
Kidney, usually called kidney, contains extremely high selenium, vitamin b2 and iron, and is a good source of dietary supplements for malnourished people. Although the visceral fat and cholesterol of these animals are lower than those in the intestine and brain, they should not be eaten in large quantities for a long time, otherwise it may lead to hyperlipidemia. For people who lack the above nutrition, it is no problem to eat it twice a month, only once or twice each time.
