Hello, fellow food safety enthusiasts! It’s your friendly neighborhood Food Safety Dad here to crack into another egg-citing topic. Today, let’s shell out some truth on a question you might have pondered while preparing your morning omelet: Can you eat eggshells?
We know eggs are a fantastic source of protein and nutrients, but what about their sturdy little homes? Eggshells are typically discarded without a second thought, but could we be tossing out a hidden treasure of nutrients? Let’s whisk through the facts and shell out some knowledge!
Eggshells are primarily made of calcium carbonate, which is a form of calcium that’s actually a common dietary supplement for those needing a boost in this essential mineral. Calcium is vital for maintaining strong bones and teeth, as well as supporting muscle function and nerve signaling in our bodies.
But, before you start crunching down on eggshells, there are a few things we need to consider. The shells are also composed of a protein matrix and contain other minerals like magnesium, phosphorus, silicon, sodium, and potassium. However, the bioavailability of these nutrients – meaning how well our bodies can absorb them – is not as straightforward as the nutrients found in the egg itself.
When it comes to food safety, we cannot ignore the potential risks associated with consuming eggshells. One of the primary concerns is the possibility of bacterial contamination, especially from bacteria like Salmonella. The Centers for Disease Control and Prevention (CDC) estimates that Salmonella causes about 1.35 million infections, 26,500 hospitalizations, and 420 deaths in the United States every year, with a significant number of these cases linked to eggs and egg products.
Contamination can occur if eggshells come into contact with the egg’s interior or with other foods and surfaces in your kitchen. This is why it’s crucial to handle eggs with care, ensuring they are properly cooked and stored.
If you’re still curious about incorporating eggshells into your diet, there is a safe way to go about it. The key is to prepare them properly to minimize the risk of bacterial contamination and to ensure they are in a form that’s more digestible.
Here’s how you can safely prepare eggshells for consumption:
Eggshell powder can be added to your diet in tiny amounts. Some people sprinkle it into their smoothies or on top of their food as a calcium supplement. However, the FDA has not provided a recommended daily intake for eggshell powder, so you should consult with a healthcare provider before adding it to your diet, especially considering potential allergies or dietary restrictions.
While we’ve established that eggshells contain calcium and other minerals, is there any research to back up their nutritional benefit? Some studies suggest that eggshell powder may have a positive effect on bone density, which could be beneficial for individuals at risk of osteoporosis. However, these studies are limited, and more research is needed to fully understand the potential health benefits and risks of consuming eggshell powder.
If you’re not quite ready to eat your eggshells, there are plenty of other ways to use them:
