Using Eggshells in Coffee to Reduce Acidity


Many people enjoy having a cup of coffee in the morning or any time of the day. Coffee can be both refreshing and wake you up, but it can also have a few downsides. One downside that many people hear about is acidity in coffee; this refers to an excess amount of acidity in your stomach after consuming too much coffee. This article will reduce the acidity of eggshells which are often thrown away when making eggs for breakfast.

What Is Acidity?

When we drink carbonated drinks, what we are drinking is cold water with dissolved gas bubbles. Carbon dioxide gas is dissolved in water when the drinks are fermented in bottles at high pressure, and the gas will be released when we open the bottle. When our stomach digests food, gastric juices containing hydrochloric acid and other enzymes will digest food. The digestion of food produces gastric juice, and the strong acidity can dissolve our teeth’ enamel if not buffered by a base that can neutralize it. There is acidity in coffee, too, whether it’s Decaf or regular.

How Do Eggshells Reduce Acidity in Coffee?

Eggshells are made from the outer layers of the egg, and these layers contain calcium carbonate. The calcite in eggshells will help neutralize the acidity that arises when our stomach digests food. Once dissolved in water, it will mimic the gastric juice produced by our stomach, and it will dissolve the enamel on teeth. When the acidity has dissolved enamel on teeth, our teeth not only get uncomfortable but can also make you more sensitive to food immediately after eating. Eggshells can reduce a large amount of acid in coffee, and it has many benefits.
