Unveiling the Truth: The Safety of Consuming Eggshells

Is it safe to eat eggshells?

When it comes to eggshells, you may be surprised to learn that they are not only edible, but also offer several potential health benefits. While rogue shell fragments in your food may not be the most pleasant experience, consuming eggshells in a controlled and prepared manner can provide you with an additional source of calcium and other essential minerals.

The nutritional value of eggshells

An eggshell is primarily composed of calcium carbonate, with calcium making up approximately 95% of its structure. It also contains smaller amounts of phosphorus, magnesium, manganese, potassium, sodium, zinc, iron, and copper. In fact, a good quality egg from the grocery store can provide about 2.2 grams of calcium, which is significant considering that the National Institutes of Health recommends that adults between the ages of 19 and 50 consume about one gram of calcium daily.
Calcium is essential for maintaining strong bones and teeth, and it also plays a critical role in several bodily functions, including muscle contraction and nerve transmission. Incorporating eggshells into your diet can help supplement your calcium intake and potentially improve bone strength and joint health.

Preparing eggshells for consumption

While eggshells are edible, it is important to prepare them safely to avoid potential risks. Raw eggshells, like raw eggs, can harbor bacteria such as salmonella, which can cause illness. Therefore, it is important to take the necessary precautions before consuming eggshells.
One recommended method is to boil the eggshells before use to kill any bacteria present. Once boiled, the shells can be dried and baked in an oven to further ensure their safety. The shells can then be ground into a smooth powder in a blender or food processor.

How to incorporate eggshells into your diet

Once you have the eggshells in powdered form, there are several ways to incorporate them into your diet:
1. Smoothies: Add a scoop of powdered eggshell to your favorite smoothie recipe. This will not only provide a calcium boost, but will also add a subtle texture to your drink.
2. Baking: Add eggshell powder to your baking recipes, such as bread, muffins, or cookies. The eggshells can increase the nutritional value of your baked goods while adding a unique flavor.
3. Coffee: Mix a small amount of powdered eggshell with coffee grounds before brewing. This can create a calcium-fortified cup of coffee, providing an alternative way to incorporate the benefits of eggshell into your daily routine.
4. Pizza topping: Sprinkle a pinch of powdered eggshell on your homemade or store-bought pizza before baking. Not only will it add a subtle crunch, but it will also provide a calcium boost to your meal.

Bottom line

Eggshells can be a safe and beneficial addition to your diet when prepared and consumed properly. They provide an important source of calcium and other essential minerals that can improve bone strength and joint health. Remember to always boil and dry the eggshells before grinding them into a powder and incorporating them into your favorite recipes. This way, you can enjoy the potential health benefits of eggshells while adding a unique twist to your culinary creations.
