Don’t throw them away anymore. Boil eggshells and say goodbye to… See more

Eggshells are one of those kitchen waste items that we usually throw away without even thinking about it.

 

However, many people do not know that these “leftovers” are actually a valuable source of nutrients, both for human health and for plants.

 

Reusing it not only reduces the amount of waste, but also offers a natural and economical way to derive real benefit.

Health benefits

Eggshells contain approximately 90% calcium carbonate, a mineral essential for strong bones and teeth. After proper disinfection and grinding, they can be consumed in small quantities as a natural supplement. To do this, the shells are boiled for about 5 minutes, dried in the sun or oven, and then ground into a fine powder.

 

The resulting powder can be added to juices, smoothies, or soups to provide the body with a calcium supplement. Some studies show that the calcium from eggshells is absorbed as well as that from dietary supplements, making it a natural way to prevent osteoporosis and strengthen bones.

 

In addition to calcium, the shells also contain traces of magnesium, phosphorus and zinc, minerals which also contribute to the proper functioning of the body. 

To help the garden

Eggshells are also widely used in gardening. One of their most common uses is as a natural fertilizer. Crushed and mixed into the soil, they enrich it with calcium and help balance the pH. This is particularly beneficial for crops like tomatoes, peppers, and eggplants, which require extra calcium.

Larger pieces of shell can be placed around plants to form a natural barrier against snails and slugs. Their sharp edges keep these pests away without the need for pesticides.

 

Another option is to add the shells to the compost: they accelerate decomposition and enrich the compost with minerals.
