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.
