Help supplement calcium

According to a study published in the Brazilian Journal of Poultry Science in 2005, eggshells contain up to 97% calcium. You can use this calcium content to maintain bone health and prevent bone-related disorders instead of taking calcium supplements.

A study published in the International Journal of Clinical and Experimental Pharmacology in 2003 also found that eggshell powder not only contains a lot of calcium but also contains fluorine and strontium. These are two substances that can improve bone and cartilage health, thereby preventing and treating osteoporosis.

Calcium in eggshells also reduces bone weakness and pain and increases bone density in patients with age-related osteoporosis. In addition, calcium in eggshells can reduce symptoms of premenstrual syndrome.

To do this, first, put the eggshells in an oven at 180 degrees Celsius for about 10 minutes. Then, let the eggshells cool and grind them into a fine powder. Add a spoonful of eggshell powder to your soup or smoothie to use once a day, to provide additional calcium to your body.

You can also follow the following specific steps:

– Boil the shells of 12 eggs over high heat to completely remove bacteria. When placing the eggshells in the pot, be sure to separate the shell fragments to prevent the eggshells from sticking together.

– Press the shells down completely into the water.

– After 5 – 6 minutes, you will see the foam accumulating in the pot. After the foam settles, continue boiling the eggshells for another 3 minutes.

– Remove the pot from the heat, drain the water, and remove the eggshells.

– Place the eggshells on a baking sheet and put them in the oven at 200 degrees F (about 93 degrees C) for 10 – 15 minutes to completely dry the shells. Alternatively, you can dry the eggshells in the microwave for a few minutes.

– Crush the eggshells with your hand and put them into a food processor for a minute.

Every day, you can use about 5g of calcium supplement functional food from eggshells. You can also mix the above powder with filtered water or fresh fruit juice to drink.

Protect your teeth

Tooth enamel contains minerals that protect teeth from weakening and cavities. However, the enamel layer is vulnerable to damage if you regularly consume sugary and caffeinated drinks or snacks. A study published in the Journal of Clinical and Diagnostic Research in 2015 found that eggshell powder can help regenerate tooth enamel in this case.

Toothpaste made from eggshells is rich in calcium and minerals, so it will strengthen and regenerate your teeth. You can make toothpaste from eggshells following these instructions:

– Boil and dry 12 eggshells to completely clean the shells. Twelve eggshells will usually be enough to fertilize about 2 – 4 plants.

– Grind the eggshells into powder by using a food processor or crushing them by hand.

– Mix the ground eggshell powder with a tablespoon of baking soda and 1 – 3 tablespoons of coconut oil to obtain a smooth and consistent mixture. You can also add 10 drops of peppermint essential oil if desired.

– Pour the mixture into a small jar and use the mixture to brush your teeth every morning.

Caring for plants

Gardeners may have bought fertilizers to sprinkle on plant roots to enrich the soil. However, eggshells, an inexpensive and readily available type of fertilizer, can also be used and can help protect plants from damage. Eggshells contain 97% calcium carbonate and also contain other minerals such as phosphorus, magnesium, sodium, and potassium. These minerals not only nourish the plants but also prevent them from becoming diseased.

You can make your own fertilizer for the garden from eggshells by following the steps below:

– Boil and dry the shells of 12 eggs to clean the eggshells. Twelve eggshells are usually enough to fertilize about 2 – 4 plants.

– Grind the eggshells into powder by using a food processor or crushing them by hand.

– Sprinkle the eggshell powder onto the soil around the plants.

– Use a claw to mix the powder into the soil. You can also wear gloves to mix the soil by hand.

– Water to help the eggshells penetrate the soil and provide nutrients to the plants.

Fertilizer made from eggshells can protect plants that are prone to calcium deficiency, such as tomatoes, eggplants, and peppers. This type of fertilizer also helps improve the growth of underdeveloped seedlings.

Remove stains

Cups used to drink coffee or tea often get stained after a while. However, replacing a stained cup with a new one is wasteful and unnecessary. To continue using your familiar cup, you can whiten it with eggshells by following these instructions:

– Boil, dry, and grind 12 crushed eggshells.

– Mix the eggshell powder with warm water and pour this mixture into the stained cup.

– Let the cup sit overnight. The stains will fade or disappear completely after one night.

The effects of eggshells help children be more creative
Eggshells can be very convenient if you have to play with children and need to keep them sitting quietly instead of running around. Children will have fun, explore, and play happily with eggshells if you know how to entertain them. A fun and educational game with eggshells is to teach children to plant in eggshells. You can play with children following these steps:

– Boil and dry the eggshells thoroughly.

– Decorate the eggshells according to your creativity and imagination with paint, markers, stickers, etc.

– Wait for the paint on the eggshells to dry.

– Add a little soil to plant seeds or grass seeds on the soil.

– Add some soil to cover the seeds and then water them.

There are also some other uses of eggshells, such as:

– Shine flower vase: Grind eggshells and put them into a vase with lemon water, then leave for a few days, shaking occasionally. The acid in the lemon water will attack the grease, while the crushed eggshells will scrape off the dirt from the glass or porcelain. The last step is to pour out all the eggshells and lemon water in the vase, rinse it with hot soapy water, and let it dry.

– Clean white clothes: Grinding eggshells and putting them in a small cloth bag made of muslin fabric and then placing it in the washing machine with white clothes can help prevent the clothes from discoloring.

– Soothe insect bites: Soaking eggshells in apple cider vinegar for a few days and then applying this mixture to insect bites or itchy bumps can be effective in soothing them. This method is effective because when soaked in apple cider vinegar, the eggshells begin to decompose, allowing the calcium carbonate in them to react with the vinegar to form calcium acetate. This is a soothing substance, similar to creams made from zinc oxide and iron oxide, that can help soothe, harden, and protect delicate skin. The eggshell and apple cider vinegar mixture has a shelf life of about 1 month if stored in the refrigerator.

– Increase tomato yield: Place a handful of crushed eggshells in the hole before planting tomato plants. They will provide the necessary calcium for plant growth and development. The lack of this nutrient can lead to blossom end rot, causing tomatoes to turn brown and water-soaked.

– Help hens lay more eggs: Adding a small amount of crushed eggshell powder to the hen’s feed can help hens lay more eggs. First, dry the eggshells and use a blender or mortar to grind them into powder. Mix a small amount of eggshell powder into the chicken’s feed. This will be a great alternative, cost-free way to provide calcium supplements from oyster shells, which are usually sold in farm supply stores. You can also use this eggshell powder for birds to eat.

– Clean used cooking oil: Used cooking oil turns black after frying food. You can use a piece of eggshell to place in the oil pan. The eggshell will absorb the carbon particles and make the oil cleaner.

– Sweeten coffee: Using eggshells in coffee may sound strange, but it is actually a good way to sweeten coffee. The calcium carbonate content in eggshells can reduce the acidity of coffee, making it less bitter. In addition, reducing the acidity in coffee also makes the beverage healthier.

Add a teaspoon of finely ground eggshell (a spoon with a capacity of 5ml) to your pure coffee powder before using the filter. The calcium carbonate in the eggshell will neutralize some of the acidity in the coffee, which can make the coffee less bitter.

– Heal wounds: The inner layer of eggshells can help heal skin wounds quickly and without leaving scars due to the compound hyaluronan. Simply apply this layer of shell membrane to the scraped area instead of medical adhesive tape, and the skin will heal quickly without the need for medication or ointments.

– Make skin smoother: One or two crushed eggshells, mixed with one egg white, will create an ideal skin treatment mixture. The eggshell powder will exfoliate dead skin cells while promoting cell regeneration, resulting in a brighter and smoother complexion. There is no better face mask than this unexpected ingredient.
