Don't throw them away again. Boil eggshells and say goodbye to... See more

 

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

However, many people are unaware 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 get real benefit from it.

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 in the oven, then ground into a fine powder.

The resulting powder can be added to juices, smoothies or soups to provide additional calcium to the body. Some studies show that 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 that 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 with the earth, they enrich it with calcium and help balance the pH. This is especially useful for crops like tomatoes, peppers, and eggplants that need more calcium.

Larger pieces of shell can be placed around plants to form a natural barrier against snails and slugs. Their sharp edges repel these pests without requiring pesticides

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

For a more sustainable daily life

Reusing eggshells is an easy step towards a more eco-friendly and sustainable lifestyle. Whether you use them to strengthen your bones or nourish your plants, you are reusing a resource that would otherwise be wasted.

So the next time you break an egg, remember: don't throw the shell away so quickly, give it a second life!
