Can we drink soda to reduce acidity? The surprising truth about carbonated beverages and heartburn

3 min read

Over 60 million Americans experience heartburn at least once a month, leading many to seek quick relief from remedies they hear about. The popular misconception suggests that drinking soda can help calm an upset stomach, but this common habit can actually make the problem much worse. So, can we drink soda to reduce acidity?

Quick Summary

Soda's high acidity and carbonation can aggravate acid reflux by increasing stomach pressure and irritating the esophagus. Understand why avoiding carbonated drinks is key for managing heartburn and discover effective alternatives for true relief.

Key Points

  • Soda Worsens Acidity: Carbonated soft drinks are acidic and increase stomach pressure, which can force stomach acid into the esophagus and trigger heartburn.

  • Carbonation is the Culprit: The bubbles in soda add gas to the stomach, causing the lower esophageal sphincter (LES) to relax and allowing reflux to occur more easily.

  • Caffeine and Sugar Aggravate Symptoms: Many sodas contain caffeine and high amounts of sugar, which are known acid reflux triggers that can further relax the LES and contribute to inflammation.

  • Opt for Safer Hydration: Plain water, ginger tea, and low-fat milk alternatives are recommended drinks for neutralizing acid and soothing the digestive tract.

  • Lifestyle Changes are Key: Managing acidity effectively involves more than just drinking; strategies like eating smaller meals, avoiding trigger foods, and elevating your head while sleeping are crucial.

  • Seek Medical Advice for Chronic Symptoms: For persistent or severe acid reflux, consulting a doctor is important to prevent serious long-term complications like Barrett's esophagus.

Why soda is the wrong solution for acidity

When you experience acidity, or acid reflux, the burning sensation is caused by stomach acid flowing back up into your esophagus. Contrary to what some believe, drinking soda will not neutralize this excess acid. In fact, most soft drinks are highly acidic themselves, often having a pH similar to or even lower than stomach acid. Introducing more acid into your digestive system is counterproductive and can exacerbate the problem.

The double-edged sword of carbonation and acid

The negative effects of soda on acid reflux stem from two key factors: its carbonation and its high acid content. The fizz in carbonated beverages adds gas to your stomach. This increase in pressure can force the lower esophageal sphincter (LES)—the muscle that separates your stomach from your esophagus—to relax or open. When this happens, stomach acid has an easier path to travel up the esophagus, causing or worsening heartburn symptoms.

Furthermore, many sodas contain caffeine and high levels of sugar, both of which are known to be acid reflux triggers. Caffeine can relax the LES muscle, while high sugar intake can contribute to inflammation and digestive issues. Combining these factors makes soda one of the worst choices for someone seeking relief from acidity.

Comparing soda to safer alternatives

To understand why soda is so harmful, compare its properties with beverages that are recommended for managing acid reflux.

Feature Carbonated Soda (e.g., Cola) Safer Alternatives (e.g., Water, Ginger Tea)
pH Level Highly acidic (e.g., pH 2.5-3.5) Alkaline or neutral (e.g., water at pH 7)
Carbonation Increases stomach pressure, relaxes LES No carbonation, no added pressure on the LES
Caffeine Often contains high levels, relaxes LES Caffeine-free (for herbal teas) or none
Sugar Very high sugar content, can disrupt digestion No added sugar (unless specified)
Electrolytes Low levels, can contribute to dehydration Some alternatives like coconut water are rich in electrolytes

Safer drinks and lifestyle changes

Instead of turning to soda, there are several effective and natural ways to combat acidity. Incorporating these healthier habits can provide lasting relief.

  • Stay hydrated with plain water: Frequently sipping water can help flush acid from the esophagus back into the stomach, neutralizing it in the process. For even better results, consider alkaline water.
  • Drink herbal teas: Options like ginger, chamomile, or licorice tea can be soothing and have anti-inflammatory properties that help reduce irritation. However, avoid peppermint tea, which can sometimes relax the LES.
  • Try low-fat milk alternatives: While full-fat dairy can worsen symptoms, skim or plant-based milks may offer some temporary relief by coating the esophageal lining.
  • Elevate your head during sleep: Gravity is your friend. Elevating the head of your bed by 6 to 8 inches can help prevent nighttime acid reflux.
  • Eat smaller, more frequent meals: Large meals can put excessive pressure on your stomach, increasing the likelihood of acid reflux. Opt for smaller portions throughout the day.
  • Avoid trigger foods: Beyond soda, other common triggers include spicy or fatty foods, citrus fruits, and tomatoes. Keeping a food diary can help you identify your specific triggers.

Medical and long-term considerations

While home remedies can be effective for occasional heartburn, frequent or severe symptoms warrant a discussion with a healthcare professional. Chronic, untreated acid reflux can lead to more serious conditions, such as esophagitis, esophageal strictures, or Barrett's esophagus. Your doctor may recommend over-the-counter medications like antacids or proton pump inhibitors, or further diagnostic tests if symptoms persist. Proper long-term management often involves a combination of dietary adjustments and lifestyle changes. For more in-depth information, you can consult resources like the Mayo Clinic's guide on Gastroesophageal Reflux Disease (GERD).

Conclusion: Choose healthier hydration for relief

In conclusion, the idea that you can drink soda to reduce acidity is a dangerous myth. The combination of carbonation and high acidity in most sodas actively works against your body’s efforts to manage acid reflux, increasing pressure on the stomach and irritating the esophagus. Instead of seeking temporary, and ultimately harmful, relief from a can of soda, focus on proven strategies like drinking water, enjoying herbal teas, and making smart dietary changes. These healthier hydration and lifestyle choices are the best path forward for real, lasting relief from heartburn and acidity.

Frequently Asked Questions

This is a widespread but incorrect belief, perhaps because the act of burping after drinking a fizzy beverage can provide a temporary feeling of relief from bloating. However, this is not a solution for acid reflux and actually increases the risk of stomach acid entering the esophagus.

No. While they lack caffeine, diet and caffeine-free sodas are still highly carbonated and acidic. The carbonation alone is enough to increase stomach pressure and trigger acid reflux.

Small sips of plain, cool water can help wash stomach acid back down into the stomach. For slightly more potent, though still temporary, relief, a mixture of baking soda and water can neutralize acid, but it should be used cautiously.

Baking soda (sodium bicarbonate) is an alkaline substance that can temporarily neutralize stomach acid, providing quick relief. However, it is not a long-term solution and should not be used excessively, as it can cause a rebound effect or other side effects, especially for those on low-sodium diets.

Most commercial ginger ales contain very little real ginger and are highly carbonated and sugary. While ginger itself is an anti-inflammatory that can help some digestive issues, the carbonation and sugar in ginger ale make it an unhelpful choice for acidity.

Yes, incorporating alkaline and non-acidic foods can help. Bananas are a natural antacid, and oatmeal can absorb stomach acid. Other good choices include ginger, leafy greens, and lean proteins.

Chronic acid reflux can lead to a number of serious complications, including esophagitis (inflammation of the esophagus), esophageal strictures (narrowing of the esophagus), and Barrett's esophagus, which is a precursor to esophageal cancer.
