If you love your morning coffee but it doesn’t seem to love you back, it could be the result of the acidity in the java. Sometimes the acid found in coffee can cause an upset in the form of heartburn, acid reflux, or even a stomach ache.

What is Baking Soda?

Also referred to as sodium bicarbonate, baking soda is a salt composed of sodium cation (Na) and a bicarbonate anion (HCO3). That’s the technical explanation, if you really wanted to know. It is also referred to as bread soda, cooking soda, and bicarbonate of soda.

What does baking soda do for us on a day-to-day basis? This white, fine powder is used in baking as a leavening agent. It reacts with acid, and carbon dioxide is released. That is what causes expansion of the batter and results in that characteristic texture that we’re looking for.

Baking soda also reacts spontaneously with acids, releasing CO2 gas. So, it can be mixed with water and used as an antacid. Similarly, a small amount of baking soda added to coffee before or after brewing can help reduce the acidity, and the effects of it, when we drink the coffee.

Baking Soda in Coffee: Why Does It Help? How Much to Use?

Coffee is acidic. The acidity occurs during the roasting process, with the shorter, lighter roasts resulting in higher acidity levels than longer roasts. Finely ground coffee beans can lead to more acid being extracted during the brewing process.

Some of us react negatively to that acidity, but we still want to enjoy our java. So we look for ways to reduce the acid and its effect on us when we drink coffee. 

Baking soda is an alkaline, so adding just a 1/4 to 1/2 teaspoon to a pot of coffee can improve the taste by making it a bit smoother, and making it a little easier to digest.

You can also add just a pinch to your brewed coffee before you drink it. 

3 reasons why baking soda in coffee is a good idea

 1 | Baking Soda Can Help Prevent Heartburn

If drinking a cup of your favorite coffee results in occasional heartburn, adding a small amount of baking soda can help neutralize the excess stomach acid that causes the symptoms. That’s because baking soda has an alkaline PH. When it mixes with an acid, it alters the pH level.

Baking soda, or sodium bicarbonate, is a natural antacid that can help neutralize stomach acid and alleviate heartburn. Heartburn, a common symptom of acid reflux and gastroesophageal reflux disease (GERD), occurs when stomach acid backs up into the tube that carries food from your mouth to your stomach.

Here’s how baking soda helps: When you ingest baking soda, it reacts with your stomach acid to produce carbon dioxide gas. This reaction can result in burping and temporary relief from heartburn symptoms because it neutralizes the acid that causes uncomfortable burning sensations.

However, it’s important to note that while baking soda can provide quick relief, it’s not a long-term solution for recurrent heartburn. Overuse of baking soda can also lead to side effects like nausea and diarrhea. It’s also high in sodium, which isn’t good for those on a salt-restricted diet.

Always consult your healthcare provider before starting any new treatment regimen, especially if you have other health conditions, are pregnant or nursing, or if symptoms persist.

Remember that if you regularly suffer from heartburn and the discomfort it causes, medical treatment might be a wise decision. 

2 | Baking Soda can help reduce Acid Reflux

Acid reflux, which can be another name for heartburn, occurs then acid from the stomach backs up into the food pipe. Sometimes a sour taste in the mouth occurs.

Baking soda, also known as sodium bicarbonate, can help manage acid reflux by neutralizing excess stomach acid. Acid reflux, also known as gastroesophageal reflux disease (GERD), is a condition where stomach acid frequently flows back into the esophagus, causing irritation and discomfort.

When baking soda is ingested, it reacts with stomach acid to produce carbon dioxide gas, water, and salt. This reaction neutralizes the stomach acid, thereby reducing the burning sensation associated with acid reflux and providing temporary relief.

However, using baking soda as a routine treatment for acid reflux isn’t recommended. While it can provide short-term relief, it doesn’t address the underlying issue causing acid reflux. Also, excessive use of baking soda can lead to side effects such as bloating, gas, and nausea. It’s also high in sodium, which can be harmful for people on a salt-restricted diet or with high blood pressure.

It’s always best to consult with a healthcare provider before starting any new treatment regimen, especially for chronic conditions such as acid reflux. Lifestyle changes, dietary modifications, and prescribed medications are often more effective long-term strategies for managing acid reflux.

If this is something that comes and goes, and doesn’t last more than a couple of weeks, our friend baking soda in coffee can help reduce the effects.

3 | Baking Soda Can Help Prevent Stomach Aches

Because baking soda is an alkaline substance it alters the pH level when it mixes with an acid. So your stomach ache can be soothed quickly. 

Baking soda, also known as sodium bicarbonate, can sometimes help soothe stomach aches by neutralizing excess stomach acid.

Stomach aches can often be caused by conditions like acid reflux or gastritis, both of which are characterized by an excess of stomach acid. When baking soda is consumed, it reacts with this acid in the stomach to produce salt, water, and carbon dioxide. This reaction helps to neutralize the acid, thereby reducing the burning sensation and discomfort associated with these conditions.

Additionally, baking soda can also help alleviate symptoms of indigestion. Indigestion, also known as dyspepsia, can cause symptoms like bloating, gas, and stomach pain. By reducing the acid level in the stomach, baking soda can help to relieve these symptoms.

However, while baking soda can provide temporary relief, it should not be used as a long-term solution for stomach aches. Regular consumption can lead to side effects such as increased thirst, nausea, and high sodium levels. Moreover, it does not address the underlying cause of the stomach ache.

If you have frequent stomach aches, it’s important to consult a healthcare provider to identify the root cause and develop an appropriate treatment plan.

Adding a small amount of baking soda to your coffee – just a pinch to a cup – can help reduce the chance of the stomach upset occurring.
