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.
For a more sustainable everyday 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’re reusing a resource that would otherwise be wasted.
So next time you crack an egg, remember: don’t throw away the shell so quickly, give it a second life!
