Nutritional components of pig lung:
Pig lung contains a lot of essential nutrients, including protein, fat, calcium, phosphorus, iron, nicotinic acid, vitamin B 1, vitamin B2, etc.
Nutritional value of lean meat:
All kinds of lean meat have similar nutrients and are easier to digest than fat meat. It contains about 20% protein, 1- 15% fat, 1% inorganic salt and the rest water. Generally speaking, pork, beef and mutton all contain high saturated fat, while poultry, chicken and rabbit meat contain less saturated fat. At the same time, it is rich in inorganic salts, especially iron (red lean meat), phosphorus, potassium and sodium, but less calcium.
Lean meat is also a good source of vitamins B 1, B2, B 12 and PP. The content of vitamin B 1 in lean meat is quite high, but it contains almost no vitamin A and almost no vitamin C. ..
There is a folk saying that "the meat tube is three days, and the soup tube is seven days", that is, the nutrition in the broth is higher than the meat in the soup, which needs to be corrected. Broth contains some water-soluble substances in lean meat, such as inorganic salts and water-soluble vitamins. There are also a small amount of water-soluble protein and hydrolysis products, such as peptides and some amino acids;
There are also some nitrogen-containing extracts, such as creatinine, creatine, carnosine and purine. These amino acids and nitrogen-containing substances can make soup delicious. The more they are dissolved, the stronger the soup taste, which can stimulate the secretion of gastric juice and stimulate appetite. However, most of the nutrients contained in lean meat remain in the meat, and the nutritional value of meat is definitely higher than that of soup. Therefore, we can't let the elderly and patients just eat broth and abandon the meat in the soup. ?
