I love eggs. Like, seriously, totally one of my favorite foods. They’re so versatile and, in paleo, are used in just about everything. So, we buy them often. And we fly through them. And I always toss the eggshells. I mean, I cannot begin to count the dozens of eggshells that have seen the inside of my garbage can. Because that’s where they go. I mean, eggshells really don’t have a purpose. Right? I’ll put it this way, if you’re throwing your eggshells away, you’re doing it wrong.
At least half of Americans are deficient in calcium which is interesting, considering each person, on average, consumes approximately 20 gallons of milk annually. Eggshells are loaded with calcium, and the numbers don’t lie. 1 cup of whole milk gives your body a nice infusion of about 276 mg calcium. Compare that with powdered eggshells where 1 tsp contains a whopping 800+ mg calcium. In fact, eggshells are so beneficial that the NIH has praised them for preventing and treating osteoporosis.
One main reason so many people suffer from cavities and dental decay is because of chronic calcium deficiency. Proper calcium intake promotes nervous system health, bone and joint health, and even helps women in particular. Researchers have discovered that a woman’s calcium levels during her cycle tend to fluctuate significantly. Right before her period, a woman’s body tends to be the lowest in calcium levels. Not by coincidence, this is when many women experience the worst of PMS symptoms: cramps, moodiness, bloating, and food cravings. In 1998, one study compared the PMS symptoms of women before and after adding a regimen of at least 1200 mg/day of calcium. Results were shocking: by the third cycle, women reported significant reduction, and even complete disappearance of PMS symptoms.
Eggshells are especially beneficial in toddlers and young children. Because of their rapid growth and development, children require an uninterrupted flow of calcium. One of the first signs of calcium deficiency is dental decay, and this is especially concerning, with approximately 42% of children displaying some degree of dental disease.
Not only are eggshells loaded with calcium, but they actually contain 27 different elements including: magnesium, phosphorus, and essential amino acids. The eggshell membranes have also been discovered to treat joint and connective tissue disorders.
Now, enough with the talky talky. Let’s get into the real reason you’re reading this post: the eggshells.
You’re going to want to save your eggshells until you have about a dozen, that way you can make a nice little batch of calcium powder. For your family’s personal ingestion, it really is best to use only organic eggshells, but any conventional eggshells can always be used for pets!
Once you’ve gathered your eggshells, you want to give them a good rinse to get rid of any egg residue. Make sure to leave the membranes intact, remember, this is a very important property of the shell.
- Rinse all eggshells, being sure to keep membranes intact
- Cover eggshells with about 6 cups water, and bring to a boil
- Allow to boil gently for about 10 minutes. This step is very important to kill all bacteria and salmonella.
- Strain eggshells, and allow to air dry, before laying out on a baking sheet lined with parchment paper.
- Bake at 200F for approximately 45 minutes.
- Powder the dried eggshells with a blender. For a finer powder, a coffee grinder results in an unnoticeable texture.
- Mix into smoothies or yogurt 1 tsp at a time.
Enjoy, and stay healthy.
Until next time,
