Some people say that pork rib soup is not that nutritious, but some people say that it is very nutritious. Is pork rib soup nutritious?

Drinking bone soup to supplement calcium is quite popular, but in fact, drinking bone soup is not a good way to supplement calcium. We all know that bones contain a lot of calcium, but very little calcium is actually dissolved into the soup. This is because the calcium in bones exists in a more stable form and has very low solubility in water.

A study measured the calcium content in pork bone soup cooked using common cooking methods (including household pressure cookers and clay pots) and found that it was only 1-1.2 mg/100 ml. And when we drink 100 grams of milk, we already have about 100 mg of calcium. If you want to reach the target value of 800 or 1000 mg per day (the recommended daily intake of calcium for ordinary adults), it cannot be easily achieved by just drinking a bowl or two of pork bone soup. Theoretically, vinegar can dissolve the stubborn calcium salts in pork bones, thereby significantly increasing the calcium content in bone broth.
