Myth: Bone soup supplements calcium.
A study on bone soup shows that in160g of bone soup, only 0.5% of protein, minerals and trace sugar, while the rest 99.5% is water. Therefore, there is no scientific basis for the statement that bone soup supplements calcium.
It is true that 99% of calcium in human and animals is stored in bones, but the calcium in bones will not dissolve into soup after simple boiling. Calcium is insoluble in water, and there is little calcium in bone soup.
The first choice for calcium supplementation should be milk, as well as green leafy vegetables, beans and nuts. In addition, although shrimp skin and sesame paste contain high calcium, they can't be used as part of people's daily diet in terms of eating frequency and quantity. And 300ml milk a day can basically meet the physiological needs of China people for calcium.
The content of soluble nutrients in soup is not high, only about 10- 15% at most. Most of the nutrients in the ingredients are still in the meat, especially the high-quality protein, iron and calcium. Therefore, drinking soup without eating meat will lead to nutritional deficiency, which is a great waste.

The second is bean products, such as tofu, dried tofu, yuba and so on.
Third, dark green leafy vegetables. Spinach, cabbage, rape, etc.
