Baking soda, also known as sodium bicarbonate, is a white crystalline powder that is commonly used in baking as a leavening agent. It’s a versatile ingredient that reacts with acidic components in batters, releasing carbon dioxide which helps the dough rise and results in a light and fluffy texture.

Beyond its use in baking, it is also widely utilized in household cleaning due to its mild abrasive and natural deodorizing properties. From freshening up your refrigerator to scrubbing your kitchen sink, baking soda has proven to be a safe and effective cleaning agent.

However, the uses of baking soda extend beyond the realm of baking and cleaning. It has been lauded for its potential health benefits and has been used as a home remedy for various conditions for centuries. This leads to an interesting question: Can you eat baking soda? This article aims to explore this topic in detail, delving into the potential benefits and risks of consuming baking soda.

What is Baking Soda?


Baking soda, known scientifically as sodium bicarbonate, is a chemical compound with the formula NaHCO3. It appears as a fine powder and is naturally alkaline, or basic (source).

As an alkaline compound, baking soda has the ability to react with acids to produce carbon dioxide gas. This reaction results in the production of small bubbles of carbon dioxide gas, a key feature that makes it an essential ingredient in baking (source).

When combined with acidic ingredients like lemon juice, vinegar, or buttermilk in a batter or dough, the reaction creates gas bubbles that cause the mixture to rise, resulting in light, fluffy baked goods like cakes and bread.

Baking soda is also referred to differently depending on the region. In Australia, New Zealand, and the UK, for instance, it’s commonly known as bicarb soda, while in the US, it’s often called baking soda (source).

How is Baking Soda Made?

Baking soda is typically produced through a process known as the Solvay process, named after its inventor, Ernest Solvay. This method involves the reaction of carbon dioxide and ammonia in a concentrated solution of sodium chloride (table salt). The result of this reaction is the formation of sodium bicarbonate crystals, which are then filtered out, washed, and heated to form baking soda.

In summary, while baking soda might seem like a simple ingredient, it’s actually a complex chemical compound with a wide range of uses, from baking to cleaning, and even health applications.

Health Benefits of Baking Soda

Baking soda, or sodium bicarbonate, is not only a key ingredient in many baking recipes and a popular household cleaner, but it also has several health benefits, particularly for oral health.

  1. Improves Oral Health: A significant body of research supports the use of baking soda for improving oral health. According to a review published in the Journal of the American Dental Association, baking soda dentifrices can have various benefits for oral health^1^. Similarly, another study found that brushing with baking soda dentifrices was more effective at plaque removal^2^.
  2. Enhances Plaque Removal: Clinical studies have shown that toothpastes containing baking soda enhance the efficacy of plaque removal compared to those without^9^. This enhanced plaque removal can lead to improved overall gingival health^6^.
  3. Neutralizes Acid in Biofilm: The acid present in dental biofilms can lead to tooth decay. Research suggests that baking soda has the ability to neutralize these acids, thereby preventing decay and promoting oral health^8^.
  4. Improves Gingival Health: A 3-month randomized clinical study indicated that fluoride toothpaste with 20% baking soda could significantly improve gingival health^6^.

Can You Eat Baking Soda?

Baking soda, or sodium bicarbonate, is a common ingredient in many recipes, particularly baked goods, and can also be consumed as an antacid. However, the question of whether it’s safe to ingest baking soda directly requires a nuanced answer.

While baking soda has been reported to offer certain health benefits, there are potential risks involved with its consumption, especially when taken in large amounts. According to WebMD, baking soda should not be taken within 2 hours of other medications as it can lower stomach acid and slow the rate at which your body absorbs some medicines.

Healthline warns that consuming large amounts of baking soda can lead to metabolic acidosis, a life-threatening condition that occurs when your body produces too much acid or when the kidneys aren’t removing enough acid from the body.

Mount Sinai further explains that overdosing on baking soda can lead to serious side effects and impair athletic performance[^3^].

However, it’s important to note that these risks are generally associated with excessive consumption. Consuming baking soda in moderate and appropriate servings can be safe[^4^]. But those who consume it on a full stomach risk experiencing serious side effects[^5^].

As a general rule, it’s always best to consult with a healthcare professional before starting any new dietary routine, including the consumption of baking soda. They can provide guidance based on individual health circumstances and needs.

Risks and Side Effects of Eating Baking Soda

While baking soda is commonly used in cooking and cleaning, consuming it directly can lead to several health issues. It’s crucial to understand the potential risks and side effects associated with eating baking soda.

  1. Overdose Risks: Consuming too much baking soda can lead to an overdose, which can cause symptoms like constipation, convulsions, diarrhea, a feeling of fullness, frequent urination, irritability, muscle spasms, and muscle weakness[^1^].
  2. Sodium Bicarbonate Toxicity: Both sodium and bicarbonate, which make up baking soda, can cause serious toxicity if swallowed in large amounts[^2^].
  3. Other Side Effects: Serious side effects of consuming baking soda can include a frequent urge to urinate, continuing headache, continuing loss of appetite, and mood or mental changes[^3^].
  4. Risk When Consumed on Full Stomach: Drinking baking soda, especially on a full stomach, can lead to serious side effects[^4^].

It’s important to consult with a healthcare professional before consuming baking soda for any health-related purposes. While it may have some benefits, the potential risks and side effects make it essential to use caution.

Expert Opinions and Advice

Many experts advise against the consumption of baking soda due to the potential risks mentioned above. However, some research suggests that baking soda consumption may boost your workout[^5^]. It’s critical to seek professional advice before incorporating baking soda into your diet or workout routine to ensure safety.

Safe Ways to Consume Baking Soda

Baking soda can be safely consumed in moderate amounts and under certain conditions. It’s important to understand that while baking soda has many potential benefits, it should not be used as a long-term treatment or cure for any medical condition without first consulting with a healthcare professional.

Here are some tips on how to safely consume baking soda:

  1. Calming Indigestion: A common use of baking soda is to calm indigestion by neutralizing stomach acid. You can add about 1/4 teaspoon of baking soda to a glass of water and drink it. This can help alleviate symptoms like heartburn and acid reflux (source).
  2. Regulating Body’s pH Level: Some suggest that a daily cup of water mixed with a teaspoon of baking soda can help regulate your body’s pH level and improve hormone balance. However, this should be done under the guidance of a healthcare professional (source).
  3. As an Antacid: Sodium bicarbonate or baking soda can be consumed as an antacid. Adults and teenagers may take one teaspoonful in a glass of water every four hours. However, the dose may need to be adjusted based on the individual’s needs and only under the supervision of a doctor (source).

Recipes or Methods that Incorporate Baking Soda

Baking soda is commonly used in baking recipes, especially those that require the dough to rise such as bread and cakes. Here, it acts as a leavening agent when combined with an acid like vinegar, buttermilk, or lemon juice.

It’s also used as a tenderizer in some cooking applications. For example, it’s often added to beans during the soaking process to soften them and reduce cooking time.
