Some people say that pigs themselves lack calcium, so is it true that drinking pig bone soup does not supplement calcium?

Cooking soup with 1 kg of meat and bones for two hours, the calcium content in the soup is only about 1.9 mg, which has nothing to do with whether pigs are calcium deficient or not. Even according to folklore, cooking bone soup with vinegar, although the overflow of minerals increases, will be converted into inorganic ions, which will not be absorbed by the human body.

The calcium supplement of bone soup is only 4% of that of milk. If you drink bone soup to supplement calcium, you need to drink about 400 bowls every day. This is an experiment. So it is still unrealistic. Although bone soup is not the first choice for calcium supplementation, it is nutritious and can still be drunk frequently.
