The effect of eating egg shells

1. Eggshells can relieve stomach pain

The main component of eggshell is calcium carbonate, which has a clear acid-inhibiting effect. When they enter the human stomach, they will cover the surface of ulcers and inflammations, thereby effectively protecting the gastric mucosa. In addition, the inner membrane of the eggshell has a good therapeutic effect on ulcerative diseases. It was once called "Phoenix Clothes" by traditional Chinese medicine practitioners. It is used as a medicine in prescriptions for treating stomach diseases. Therefore, it can help the eggshell protect the gastric mucosa. Wash and break the eggshells, put them into an iron pan and fry them over low heat until they turn yellow (do not burn them), then grind them into powder, the finer the better. Take one eggshell a day, divided into 2 to 3 times with water before or after meals. It has analgesic and acid-reducing effects on patients with duodenal ulcers, stomach pain, and excessive stomach acid.

2. Can eating egg shells supplement calcium?

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

According to the National Collection of Chinese Herbal Medicine, 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 only patients with rickets and children who need calcium supplementation. Everyone can take appropriate calcium supplementation according to their own physical condition and using appropriate methods.

Precautions for eating egg shells

1. Eggshells are made of calcium carbonate. After calcium carbonate enters the human body, it can react with stomach acid to generate free calcium ions that can be absorbed by the human body. You should know that some health products also contain eggshell ingredients. If the intake is too much, it will form calcium-related insoluble substances and may cause stones.

2. Therefore, the statement that eggshells can be eaten and that eating eggshells can supplement calcium is correct. When people eat it, they must sterilize it at high temperature to kill bacteria. But not everyone is suitable for eating eggshells to supplement calcium.
