Bone soup is a clear soup drink that people like to drink, not only because it is nutritious, but also because it has a good therapeutic effect. Bone soup can play an anti-aging role. This is because bone marrow is the most important thing in human bones, and both red blood cells and white blood cells in blood are formed in bone marrow. With the growth of age and the aging of the body, the function of bone marrow to produce red blood cells and white blood cells gradually declines, which directly affects the ability of human metabolism. The collagen contained in bone soup can just enhance the body's ability to make blood cells. Therefore, for middle-aged and elderly people, drinking bone soup can slow down bone aging; Similarly, bone soup can also be beneficial to the bone growth of teenagers. However, how to cook and eat bone soup is very particular, otherwise it will not only lose nutrients, but sometimes it will be counterproductive. Therefore, we should pay attention to the following two points: 1. Matters needing attention when stewing bone soup 1. Stew bone soup (or fish soup), preferably with cold water. Because there is always a little meat on the bone, if hot water or boiled water is poured into the pot at the beginning, the surface of the meat is suddenly exposed to high temperature, and the outer layer of the meat protein will solidify immediately, so that the inner layer of protein cannot be fully dissolved into the soup. Only by adding enough cold water and heating slowly can protein be fully dissolved in the soup, and the soup is more delicious. 2. Add a little vinegar after the water is boiled, so that the phosphorus and calcium in the bones are dissolved in the soup, so that the stewed soup tastes delicious and is easily absorbed by the stomach. At the same time, don't put salt in the stew too early. Because salt can make the water contained in meat quickly lose, it will accelerate the solidification of protein and affect the umami taste of soup. Let's talk about the steps of boiling bone soup first: 1. Put the bones in warm water and wash them one by one with a rag, especially the blood foam and impurities at the joints of the bones. 2. Chop the straight bone, split it into two halves, put it in a pot, add onions and ginger, and then add cold water, preferably at one time. 3. Cook with high fire and skim off the floating foam. 4. After skimming the floating foam (depending on the meat quality, it may take 1-2 times), turn to low heat and simmer, and then pour in about 50 K. 5 wine. From the point of view of nutrition acquisition, vinegar can be added appropriately after water is boiled, because vinegar can dissolve phosphorus and calcium in bones into soup; At the same time, don't put salt too early, because salt will quickly lose the water contained in the meat, accelerate the solidification of protein and affect the delicious soup. 6, stew for 2-3 hours before the soup, that is, complete the soup! How's it going? Generally, pig bone soup can be used continuously. Cook at home for about 1-3 hours, which can be used twice until the vermicelli is crisp, the bone color is gray, the soup is delicious and the fat nutrition is exhausted. Second, don't drink bone soup in the early stage of fracture. In life, people often have the habit of drinking bone soup after fracture in order to supplement calcium and make the fracture heal as soon as possible. This habit is extremely wrong. In fact, the more you drink bone soup in the early stage of fracture, the slower the fracture healing. Of course, in the middle and late stage of fracture healing, that is, the original callus formation stage and callus transformation molding stage, because the osteoid tissue of organic fiber gradually calcifies to form new bone, and the transformation is strengthened to form normal bone, the ossification of osteoid tissue needs enough calcium and phosphorus, so it is still very beneficial to supplement bone soup at this time.
