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

However, many people don’t 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 obtain real benefits.

Health benefits

Eggshells contain approximately 90% calcium carbonate, an essential mineral for strong bones and teeth. After proper disinfection and crushing, they can be consumed in small quantities as a natural supplement. To do this, boil them for about 5 minutes, dry them in the sun or in the oven, and finally grind them 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 in 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, 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 soil, they enrich it with calcium and help balance the pH. This is especially 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 peels to the compost: they accelerate decomposition and enrich the compost with minerals. For a more sustainable everyday life

Reusing eggshells is a simple step towards a greener, more sustainable lifestyle. Whether you use them to strengthen your bones or nourish your plants, you’re repurposing a resource that would otherwise go to waste.

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