Egg’s shell is natural source of minerals and contains 90% calcium. Calcium is easily absorbed by our body because its chemical composition is almost identical to human’s teeth and bones.
If consumed in larger amounts, calcium will not only get rid of lack of calcium-symptoms, but it will also prevent osteoporosis’ development, stimulate the bone narrow in producing blood cells and help when it comes to treating high cholesterol levels and high blood pressure.
Egg shell also contains iron, zinc, copper, manganese, fluorine, phosphorus, chromium and molybdenum. Therefore, many experts recommend shell eggs as a natural and very effective calcium supplement.
It is recommended to enter 1.5 to 3 grams of crushed shells a day.
Here are several ideas on how to use egg shell and what to use them for:
1. Make Your Coffee More Drinkable
Do you hate how bitter your morning cup of coffee is? Here are two pieces of advice: read our coffee primer, and add crushed up eggshells to the grounds when you brew your cuppa.
I know, I know: it sounds weird and gross. But the eggshells serve to clarify the coffee, which helps reduce the bitter taste (and they add no taste of their own). However, make sure that you’re using eggshells that have been washed (note: in America, all eggs are washed before being sold).
2. Feed Your Compost Pile
If you have a compost pile, you should be sending almost all of your rogue eggshells that way. The shells will decompose quickly and naturally, and when they do they’ll add lots of calcium to your pile. It’s a common misconception that you can’t put eggshells in compost piles because the shell is too hard, but this is far from the truth.
It’s also a common misconception that unwashed eggshells will contaminate a compost pile with salmonella, or that they won’t degrade because of the egg proteins. In actuality, there’s not enough egg left on the inside of the shells to impact your compost pile, and the heat from the compost will kill any potential salmonella bacteria.
