The Chinese people often say: what to eat to make up for what. Therefore, many people believe that drinking bone broth can replenish calcium, can promote fracture healing, and can prevent and treat osteoporosis. In fact, this is a misconception. According to current scientific experiments, the calcium extracted from the bones is less than one percent of the milk, so boiling bone broth for calcium can not play a calcium role, but only to comfort themselves. Moreover, the bone marrow in the bones is a large fat bank, boiled bone soup not only contains little calcium, but also contains a lot of fat, especially the middle-aged and elderly patients with fractures, reduced activity, often drink such bone soup will cause hyperlipidemia, which is very harmful. In addition, some people believe that the fat droplets in bone soup, and diet (of course, including bone soup) in the calcium, combined into large molecules, can not penetrate the semi-permeable membrane of the small intestine mucosa, can not be absorbed by the body, but with the feces out of the body. In fact, if we can do without partiality, the diet in three meals a day, can provide 400-500 mg of calcium, if added to a variety of dairy products, soy products and other foods, generally can meet the amount of calcium needed.
