Whether bone broth is good or not is related to the cooking method, but bone broth contains very little calcium and cannot be a good food source of calcium supplementation. Bone broth is mainly made from cow or pig bones, which contain a lot of calcium, but this kind of calcium is a calcium salt, which is not easily soluble in water, and ordinary cooking usually can’t make it into a free state. Therefore, no matter how to boil bone broth in the free calcium content is very small, and can not effectively supplement calcium. For people who need to supplement calcium, daily intake of calcium-rich foods, such as river shrimp, dried tofu, seaweed, black fungus, soybeans, tofu flower, milk, etc.; if necessary, follow the doctor’s advice to use calcium supplements, vitamin D preparations, etc. to increase the body’s calcium content, as well as to promote the absorption of calcium.
