Can You Eat Eggshells? Things to Know Before Eating Them

Eggshells cannot be eaten. Many people crush the eggshells and mix them with water to drink as a calcium supplement, but this is wrong. Because the calcium in eggshells cannot be digested and absorbed by the human body, so if you really eat them this way, you will get kidney stones.

Eggshells are often an overlooked treasure trove of nutrition. Eggshells are formed naturally. Testing by various modern scientific methods has shown that eggshells contain 83—85% calcium carbonate, 15—17% protein, and a variety of trace elements (zinc, copper, manganese, iron, selenium, etc.). Each eggshell contains 2-2.5 grams of calcium. However, the calcium in eggshells cannot be directly absorbed by the human body. If this large amount of calcium could be converted into active calcium that the human body can absorb, it could effectively supplement calcium and help the human body prevent bone aging and osteoporosis.

The Many Uses of Eggs

1. As Fertilizer

Crush eggshells and put them in flower pots. They not only retain moisture but also provide fertilizer for plants, because eggshells contain calcium and phosphorus, which can speed up plant growth.

2. Treating Burns

Sometimes when we are cooking or boiling water we get burned. Peel off the outer shell of the egg and keep the inner membrane, then place it on the burned area to reduce inflammation and relieve pain.
