Here’s a detailed look at eggshells:
Description
- The hard outer covering of a chicken egg.
- Mainly composed of calcium carbonate (about 95%), with small amounts of protein and other minerals.
- Typically discarded after using the egg, but can be repurposed.
Uses
1. Calcium supplement
- Eggshells can be cleaned, boiled, baked, and ground into a fine powder.
- 1 teaspoon of powdered eggshell contains roughly 2,000 mg of calcium.
- Can be added to smoothies, yogurt, or baked goods.
- Tip: Ensure it’s finely ground to avoid sharp edges that can harm the digestive tract.
2. Gardening
- Crushed eggshells can be sprinkled in soil to:
- Add calcium to plants
- Repel pests like slugs and snails
3. Household uses
- Polishing metals or cleaning cookware
- Natural abrasive for scrubbing
Safety
- Must boil or bake before consuming to kill bacteria like Salmonella.
- Grind very finely to prevent choking or mouth/throat injury.
- Not a substitute for a balanced diet but a supplemental source of calcium.
💡 Fun fact: Some people mix eggshell powder into smoothies or oatmeal as a natural calcium boost, which can support bone health and, indirectly, heart health too.
