What Happens If You Eat Egg Shells

Eating eggshells can potentially scrape or puncture your throat, and there is a risk of bacteria, like salmonella, if the eggshells are raw. However, eggshells can also be a good source of calcium and can be consumed in powdered form for added health benefits like strengthening bones and reducing the risk of certain diseases.

In addition, the hydrochloric acid in the stomach can dissolve eggshells made from calcium. While rough patches or bumps on eggshells are usually harmless and can be brushed off, it is important to ensure proper nutrition and proper handling of eggs to avoid any potential risks.

The Nutritional Value Of Egg Shells

Eating egg shells may actually have hidden benefits. The shells are completely edible and may even be more nutritious than the yolk, as they are made of calcium. However, be cautious of consuming sharp pieces that could potentially scrape or puncture your throat, and ensure the shells are from cooked eggs to avoid bacteria risks.

Egg shells are often overlooked and discarded without realizing their potential nutritional benefits. Contrary to popular belief, egg shells are not only edible but also rich in various essential nutrients. So, what exactly is the nutritional value of egg shells?

Let’s explore:

Calcium Content In Egg Shells

  • Egg shells are a fantastic source of calcium, with nearly 90% of their composition consisting of this vital mineral.
  • Just one gram of eggshell can provide approximately 800-1000 mg of calcium, which is equivalent to the daily recommended intake for adults.
  • Calcium is crucial for the development and maintenance of strong bones and teeth.
  • Adequate consumption of calcium may also help prevent osteoporosis and other bone-related conditions.

Other Nutrients Found In Egg Shells

  • In addition to calcium, egg shells contain small amounts of other minerals, including magnesium, potassium, and phosphorus.
  • These minerals contribute to proper muscle function, nerve transmission, and cellular energy metabolism.
  • Egg shells also contain trace amounts of iron, copper, zinc, and selenium, which play vital roles in numerous bodily functions.

How To Consume Egg Shells

  • To reap the nutritional benefits of egg shells, they must be properly prepared before consumption.
  • It is crucial to ensure that the egg shells are thoroughly cleaned and free from any residue or bacteria.
  • One common practice is to boil the egg shells for around 10 minutes to sanitize them and make them easier to handle.
  • Once boiled, the shells can be crushed into fine powder form using a blender or mortar and pestle.
  • The powdered egg shells can then be added to various dishes, such as smoothies, soups, or baked goods, in small quantities.

Precautions To Consider

  • While egg shells can provide valuable nutrients, caution should be exercised when consuming them.
  • Ensure that the egg shells are free from any contaminants or pesticides, preferably through the use of organic or free-range eggs.
  • It is advisable to consult with a healthcare professional before incorporating egg shells into your diet, especially if you have any underlying health conditions or allergies.
  • Remember that moderation is key; excessive calcium intake can have adverse effects on health.

Egg shells are not just waste but a potential source of valuable nutrients. With their high calcium content and other essential minerals, egg shells can be a beneficial addition to a balanced diet. However, it is essential to take necessary precautions and ensure proper preparation before consuming them.

Potential Risks Of Eating Egg Shells

Consuming egg shells may pose potential risks, as the sharp edges could scrape the throat and there is a risk of bacteria like salmonella if the shells are from a raw egg. It is advisable to avoid eating egg shells and instead consider other calcium-rich sources for a safer and healthier alternative.

Eating egg shells may not be as harmless as it seems. While they contain calcium and other minerals that could offer health benefits, there are some potential risks to be aware of. Let’s take a look at the possible dangers associated with consuming egg shells:

Choking Hazards And Risks:

  • Sharp edges: Egg shells can have sharp edges, especially when crushed or broken into small pieces. These sharp edges pose a choking hazard, as they can scratch or puncture the throat if not chewed properly.
  • Size of shell fragments: Even if the egg shells are finely crushed, there is still a risk of inhaling or swallowing larger shell fragments, which can cause choking or blockage in the airways or digestive system.

Bacterial Contamination Concerns:

  • Salmonella risk: The outer shell of eggs can potentially be contaminated with bacteria, such as Salmonella. Consuming egg shells increases the risk of ingesting harmful bacteria, leading to food poisoning and gastrointestinal issues.
  • Improper cleaning: If the eggshells are not properly cleaned before consumption, they may retain bacteria from the chicken’s feces or other contaminants, further increasing the risk of bacterial infection.

Digestive System Implications:

  • Irritation and damage: The sharp edges of egg shells can cause irritation and damage to the delicate lining of the digestive system, including the esophagus, stomach, and intestines. This can lead to discomfort, inflammation, and potential bleeding.
  • Difficulty in digestion: Egg shells are primarily composed of calcium carbonate, a compound that is not easily digested by the human body. The digestive system may struggle to break down the shells, resulting in digestive issues such as bloating, gas, and constipation.

It’s important to note that while egg shells can present potential risks, these risks can be minimized or avoided altogether by following proper food safety measures. Always ensure that eggs are thoroughly cooked, and consider discarding the shells to reduce the chances of encountering these potential dangers.

How To Safely Consume Egg Shells

Eating egg shells is generally safe and can even offer some nutritional benefits. The shells are edible and may contain more nutrients than the yolk, making them a potential source of calcium. However, it’s important to avoid sharp pieces and ensure that the shells come from properly cooked eggs to minimize the risk of bacteria.


Egg shells are often overlooked and thrown away as waste, but did you know that they can actually be consumed? Yes, that’s right! Egg shells are not only edible but can also provide some nutritional benefits. However, it is important to follow proper preparation and cooking methods to ensure their safe consumption.

In this section, we will discuss how to prepare and clean egg shells, cooking methods to reduce risks, and incorporating egg shells into recipes.

Preparing And Cleaning Egg Shells:

To safely consume egg shells, it is crucial to properly prepare and clean them. Here are the steps you should follow:

  • Start by collecting eggshells from organic, free-range eggs. Make sure to avoid shells from conventionally farmed eggs, as they might contain harmful chemicals or antibiotics.
  • Rinse the shells thoroughly under running water to remove any dirt or debris.
  • Place the shells in a pot of boiling water and let them simmer for 5-10 minutes. This will help kill any bacteria present on the shells.
  • Allow the shells to cool completely before handling them further.
  • Once cooled, gently remove the thin membrane inside the shell. This can be done by carefully peeling it off with your fingers or using a small knife.

Remember, proper preparation and cleaning are essential to eliminate any potential contaminants present on the shell.

Cooking Methods To Reduce Risks:

While consuming egg shells can be safe, it is important to reduce any potential risks associated with eating them. Here are some cooking methods that can help minimize these risks:

  • Crushing the egg shells into a fine powder: Grinding the shells into a powder form can make them easier to incorporate into various recipes. It also reduces the chances of swallowing large, sharp pieces of shells.
  • Baking the shells: Another method to reduce the risk of consuming harmful bacteria is to bake the shells before using them. Simply spread the shells on a baking sheet and bake them at a low temperature (around 250°F) for 10-15 minutes. This helps kill any remaining bacteria.
