Baking soda, scientifically known as sodium bicarbonate, is a versatile compound found in nearly every household. It’s a staple in baking, cleaning, and even personal care. But beyond its common uses, the question arises: does eating baking soda offer any health benefits? While some proponents claim it can alleviate various ailments, it’s crucial to examine the science behind these claims and understand the potential risks involved.
Understanding Baking Soda: Its Properties and Uses
Sodium bicarbonate is a white, crystalline powder that is naturally alkaline. This means it has a pH greater than 7. Its primary function in baking is to act as a leavening agent, releasing carbon dioxide gas that causes dough to rise. This reaction occurs when baking soda is combined with an acidic ingredient like vinegar, lemon juice, or buttermilk.
Beyond baking, its mild abrasive properties make it an effective cleaning agent for scrubbing surfaces and deodorizing unpleasant smells. It’s also found in some toothpastes and mouthwashes due to its ability to neutralize acids and freshen breath. Some even use it in homemade beauty remedies.
The Purported Health Benefits of Consuming Baking Soda
The potential health benefits of ingesting baking soda largely stem from its ability to neutralize acids. The human body strives to maintain a delicate pH balance, and proponents suggest that baking soda can help restore this balance when the body becomes overly acidic.
Alkalizing the Body: The Theory Behind the Claim
The “alkaline diet” has gained popularity in recent years, with proponents claiming that an acidic environment in the body can contribute to various health problems, including inflammation, fatigue, and even cancer. Eating alkaline foods and beverages, like those supposedly enhanced with baking soda, is said to counteract this acidity and promote better health. However, it’s important to note that the human body has its own sophisticated mechanisms for regulating pH levels, primarily through the kidneys and lungs. Simply consuming alkaline substances doesn’t drastically alter the body’s overall pH in healthy individuals.
Potential Relief from Heartburn and Indigestion
One of the most commonly cited benefits of consuming baking soda is its ability to relieve heartburn and indigestion. Heartburn occurs when stomach acid flows back into the esophagus, causing a burning sensation. Baking soda can neutralize this acid, providing temporary relief. This is because baking soda is a base (alkaline) and stomach acid is, well, an acid. The reaction is simple acid-base neutralization.
However, it’s important to note that this is a short-term solution and should not be used as a regular treatment for heartburn. Frequent use of baking soda can have side effects, which we’ll discuss later. Furthermore, it’s crucial to consult a doctor to determine the underlying cause of heartburn and receive appropriate treatment.
Potential Benefits for Exercise Performance
Some athletes use baking soda as an ergogenic aid, meaning a substance that enhances athletic performance. Research suggests that baking soda may improve performance in high-intensity exercises lasting between one and seven minutes. This is because during intense exercise, lactic acid builds up in the muscles, causing fatigue. Baking soda can help buffer this lactic acid, delaying fatigue and allowing athletes to push themselves harder for longer.
However, the benefits are typically seen in very specific scenarios and may not be applicable to all types of exercise or individuals. Additionally, the effective dose for athletic performance is relatively high, which can increase the risk of side effects.
Kidney Health: A Cautious Consideration
In some specific medical contexts, doctors may prescribe sodium bicarbonate to patients with kidney disease. This is because kidney disease can lead to a buildup of acid in the body (metabolic acidosis). Sodium bicarbonate can help neutralize this acid and protect kidney function.
However, this is a medical treatment administered under strict medical supervision. It is absolutely crucial to never self-treat kidney problems with baking soda. Doing so can have serious and even life-threatening consequences.
The Risks and Side Effects of Consuming Baking Soda
While baking soda may offer some potential benefits, it’s important to be aware of the risks and side effects associated with its consumption.
Electrolyte Imbalance
Baking soda is high in sodium. Consuming too much baking soda can lead to an electrolyte imbalance, particularly an increase in sodium levels (hypernatremia) and a decrease in potassium levels (hypokalemia). This imbalance can cause symptoms such as muscle weakness, cramps, irregular heartbeat, and even seizures. People on low-sodium diets, or with kidney or heart conditions, should be especially cautious.
Metabolic Alkalosis
While baking soda is sometimes used to treat metabolic acidosis, excessive consumption can lead to the opposite problem: metabolic alkalosis. This condition occurs when the body becomes too alkaline. Symptoms of metabolic alkalosis can include confusion, muscle spasms, nausea, vomiting, and slow breathing.
Gastrointestinal Issues
Baking soda can cause gastrointestinal problems, such as nausea, vomiting, diarrhea, and stomach pain. The release of carbon dioxide in the stomach can also lead to bloating and gas.
Interactions with Medications
Baking soda can interact with certain medications, affecting their absorption and effectiveness. For example, it can reduce the absorption of aspirin and certain antibiotics. It’s crucial to talk to a doctor or pharmacist before consuming baking soda, especially if you’re taking any medications.
Pregnancy and Breastfeeding
Pregnant and breastfeeding women should avoid consuming large amounts of baking soda. It can disrupt electrolyte balance and potentially harm the fetus or infant.
Safe Usage Guidelines: If You Choose to Consume Baking Soda
If you choose to consume baking soda for its potential health benefits, it’s crucial to do so safely and responsibly. Here are some guidelines:
- Consult your doctor: Before consuming baking soda, especially if you have any underlying health conditions or are taking medications, consult your doctor. They can assess your individual risks and advise you on whether it’s safe for you to consume baking soda.
- Use sparingly: Use baking soda sparingly and only when necessary. Avoid consuming it regularly or in large quantities.
- Dilute properly: Always dilute baking soda in water before consuming it. This helps minimize its irritating effects on the digestive system. A common recommendation is to mix ½ teaspoon of baking soda in 4 ounces of water.
- Monitor for side effects: Pay attention to any side effects you experience after consuming baking soda. If you experience any concerning symptoms, such as nausea, vomiting, or muscle weakness, stop consuming it and consult your doctor.
- Avoid long-term use: Baking soda is not intended for long-term use. If you’re using it to treat heartburn or indigestion, consult your doctor for alternative treatments that are safe for long-term use.
The Verdict: Is Eating Baking Soda Beneficial?
While baking soda can provide temporary relief from certain conditions like heartburn and may have limited benefits for athletic performance, the potential risks and side effects associated with its consumption should not be ignored. The purported benefits of “alkalizing the body” are largely unsupported by scientific evidence. For most individuals, the risks of consuming baking soda outweigh the potential benefits.
It’s always best to focus on a balanced diet, regular exercise, and other healthy lifestyle habits to maintain optimal health. If you’re experiencing any health problems, consult a doctor for appropriate diagnosis and treatment.
Consuming baking soda is not a substitute for medical care. Never self-treat serious health conditions with baking soda. Always seek professional medical advice.
Here’s a summary table of the risks and benefits discussed:
| Potential Benefits | Potential Risks |

Ultimately, the decision of whether or not to consume baking soda is a personal one. However, it’s essential to make an informed decision based on scientific evidence and professional medical advice.
Can baking soda help with heartburn?
Baking soda, also known as sodium bicarbonate, can act as an antacid, temporarily neutralizing stomach acid. This can provide quick, short-term relief from heartburn or acid indigestion. However, it’s important to use it sparingly and as directed, as overuse can lead to side effects.
When using baking soda for heartburn, dissolve a small amount (typically ½ teaspoon) in a glass of water and drink it slowly. Avoid using it regularly or in large doses, as it can disrupt the body’s natural acid balance and potentially cause metabolic alkalosis, a condition where the blood becomes too alkaline.
Is baking soda a good way to treat a urinary tract infection (UTI)?
While some anecdotal evidence suggests that baking soda might help alleviate UTI symptoms by making urine less acidic, it is not a substitute for proper medical treatment. UTIs require antibiotics to effectively eliminate the bacteria causing the infection. Relying solely on baking soda can worsen the infection and lead to complications.
If you suspect you have a UTI, consult a doctor for diagnosis and appropriate antibiotic treatment. Baking soda may offer temporary relief from discomfort, but it’s crucial to address the underlying bacterial infection with prescribed medication. Delaying proper treatment can lead to kidney infections and other serious health issues.
Does baking soda whiten teeth?
Baking soda is a mild abrasive that can help remove surface stains from teeth, potentially leading to a perceived whitening effect. Many toothpastes contain baking soda as an ingredient for this reason. However, it’s important to use it cautiously, as excessive use can erode tooth enamel.
While baking soda can remove some surface stains, it doesn’t bleach the teeth like professional whitening treatments. It’s best to use baking soda sparingly and in conjunction with regular brushing and dental hygiene. If you have sensitive teeth, consult your dentist before using baking soda as a teeth whitening method.
Can baking soda help with skin conditions like eczema?
Baking soda baths can sometimes provide temporary relief from itching associated with eczema. The alkaline nature of baking soda may help neutralize the acidity of the skin’s surface and reduce inflammation. However, baking soda can also be drying, so it’s essential to moisturize the skin well afterward.
When using baking soda for eczema, add a small amount (about ¼ cup) to a lukewarm bath and soak for 10-15 minutes. Avoid using hot water, as it can further irritate the skin. If you experience any adverse reactions, such as increased dryness or irritation, discontinue use and consult a dermatologist.
Is it safe to drink baking soda daily?
Drinking baking soda daily is generally not recommended and can be harmful. While it may offer temporary relief from certain conditions, regular consumption can disrupt the body’s electrolyte balance, leading to metabolic alkalosis, heart problems, and muscle weakness. It can also interact with certain medications.
Occasional use of baking soda for specific purposes, such as heartburn relief, may be acceptable in small doses. However, it should not be a daily habit. If you have concerns about your health, consult a doctor to discuss safer and more effective treatment options. They can provide personalized advice based on your individual needs and medical history.
Does baking soda help with kidney disease?
In certain cases, under strict medical supervision, baking soda might be prescribed to patients with chronic kidney disease to help manage metabolic acidosis, a condition where the body produces too much acid. However, this is a highly specific and controlled medical treatment, not a home remedy.
It’s crucial to emphasize that individuals with kidney disease should never self-treat with baking soda. Improper use can lead to dangerous electrolyte imbalances and worsen kidney function. Always consult a nephrologist or other qualified healthcare professional for guidance on managing kidney disease and its associated complications.
Can baking soda improve athletic performance?
Some athletes use baking soda as an ergogenic aid, believing it can buffer lactic acid buildup in muscles during intense exercise and delay fatigue. This is known as sodium bicarbonate loading. While some studies suggest potential benefits for short-duration, high-intensity activities, the effects are not consistent and vary depending on the individual.
Sodium bicarbonate loading can cause gastrointestinal distress in some individuals, including nausea, vomiting, and diarrhea. It’s important to carefully consider the potential risks and benefits before using baking soda for athletic performance. Consulting with a sports medicine professional or registered dietitian is recommended to determine if it’s appropriate for your specific needs and goals.
