Eggshells are more than just kitchen waste—they have nutritional and practical uses. Here’s a detailed overview:
1. Nutritional Value
- Calcium-rich: Eggshells are about 95% calcium carbonate, which can help support bone health if properly prepared.
- Other minerals: Small amounts of magnesium, phosphorus, and strontium.
How to Use for Nutrition
- Clean and bake: Boil or bake shells at 200°F (90°C) for 10 minutes to kill bacteria.
- Grind to powder: Use a coffee grinder or mortar to make a fine powder.
- Add to food: Mix a tiny amount (1/2 teaspoon) into smoothies or baked goods.
⚠ Important: Never consume large amounts directly—too much calcium can be harmful.
2. Garden Uses
- Natural fertilizer: Eggshell powder can enrich soil with calcium.
- Pest deterrent: Crushed eggshells around plants may discourage slugs and snails.
3. Household Uses
- Cleaning scrub: Crushed eggshells with soap can scrub stubborn pots or stains.
- Seed starters: Eggshell halves can be filled with soil to start seedlings.
4. Tips & Safety
- Always wash eggshells thoroughly to remove any bacteria (like Salmonella).
- Dry completely before grinding or storing.
- Use sparingly in food or garden to avoid overdoing calcium.
💡 Fun Fact: Eggshells take hundreds of years to decompose naturally, so reusing them in food, garden, or cleaning is eco-friendly.
