Is it true that egg shells can supplement calcium?

Eggshells do have a certain calcium supplement effect, because the main component of eggshells is calcium carbonate, which can form calcium acetate after reacting with acetic acid, which has a certain calcium supplement effect. Of course, pure eggshells are not conducive to calcium supplementation, because this large molecular calcification is not easily absorbed by the body. You can use the method of soaking eggs in vinegar, which can achieve a certain calcium supplement effect and is also effective in preventing osteoporosis.

Is it true that egg shells can supplement calcium? 1. Is it true that egg shells can supplement calcium?

First, let's analyze the structure of the eggshell. There are about 10,000 absorption pores on the surface of the eggshell, so it is definitely not an exaggeration to call it "loose and porous". Therefore, it is more conducive to being dissolved by stomach acid than compacted powdered calcium tablets, and it is also easier to react with acetic acid to form calcium acetate. Secondly, active calcium is made from animal food. In today's polluted environment, there must be a lot of heavy metal accumulation, and eggs are relatively safe.

2. Why is eggshell calcium not conducive to absorption?

Absorption, absorption, the prerequisite is that it has to be dissolved before it can be absorbed. The reason why eggshell calcium is not easy to absorb is mainly because eggshell calcium is mostly calcium carbonate, which is difficult to dissolve in water. It must be dissolved in an acidic solution and then become ionized calcium before it can be absorbed. Therefore, people who lack gastric acid have insufficient acidity in the upper intestine and will definitely be unable to absorb calcium tablets made from calcium carbonate. It is better to choose calcium tablets made from calcium acetate, calcium lactate, or calcium gluconate.

3. There is medical evidence that eating egg shells can supplement calcium

There is medical evidence that eating egg shells can supplement calcium. According to the records in the "National Compilation of Chinese Herbal Medicines", eggshells can "cure rickets in children. Eggshells contain more than 90% calcium carbonate and a small amount of sodium carbonate, hydrogen phosphate and other substances. Grinding them into powder and taking them orally can cure rickets in children." It is not necessarily rickets and children need calcium supplements. Everyone can use appropriate methods to supplement calcium according to their physical condition.

4. How to supplement calcium with egg shells

Wash the eggshells, roast them over low heat until crispy, grind them into powder, and then mix them into rice to make calcium rice. A small bowl of calcium rice plus a small dish of vegetable and egg salad can not only supplement the nutrients needed by the human body but also help lose weight and beautify.
