Eggshells are known to be added to coffee to avoid waste, and it probably made the coffee better because it’s made up mainly of calcium. This easily leaches into warm, acidic liquids such as coffee which has a pH between 4. and 5.

The eggshells likely raised the pH and made the coffee taste milder, similar to a low amount of lime. The eggshells probably added dietary calcium to the coffee, which Grandma Ruth would love if she knew about it.

Recent research shows that eggshell powder can be used as a dietary supplement to increase the formation of cartilage and bone in osteoporosis patients. It also strengthens bones in postmenopausal women.

Hello, I’m Pete and I’m currently based in the west of Scotland, in a small place called Rosneath, where I’m exploring my garden adventures. I personally started gardening around 6 years ago and initially, I started out by growing my favorite fruits and berries, such as strawberries, Raspberries & Gooseberries. Since then I’ve added a lot of vegetables and working closely with my neighbor, it’s been a lot of fun.
