10 Acidic Foods To Avoid For Preventing Acidity And Heart Burn

You must have come across the topic of acidic foods to avoid and prevent any stomach issues. While acidic foods are a norm in a balanced diet with advantages for digestive health, a balanced pH level is essential for proper bodily function. Excessive intake of acidic foods can lead to various health issues like acid reflux, heartburn, indigestion, and even long-term conditions like osteoporosis in women and kidney stones.

Citrus fruits, tomatoes, and vinegar-based goods are common offenders. Although nutrient-dense, these foods can upset the body's normal pH balance if ingested excessively. Recognising and reducing these acidic meals may enhance overall vitality by promoting improved digestive health, reducing discomfort, and supporting a more alkaline environment. 

This article will highlight some common acidic foods to avoid and provide a list of non-acidic foods that can help balance gut pH. So, without further ado, let’s get into the topic!

What Are Acidic Foods?

Foods are classified as acidic, neutral, or alkaline based on their pH levels. The pH scale spans from 0 to 14, with foods below 7 classified as acidic and those above 7 as alkaline. Even though the body is naturally capable of maintaining its pH balance, consuming a lot of acidic foods regularly can strain the system and cause disruptions in balance.

Acidic foods can contribute to acid build-up in the stomach, triggering acid reflux and other poor digestion symptoms. They can also have broader health implications, like bone density and dental health.

What Are The 10 Most Acidic Foods?

The following list elucidates the most common acidic foods to avoid: 

1. Citrus Fruits

Citrus fruits like lemons, limes, oranges, and grapefruits are highly acidic due to their high citric acid content. The pH of these fruits typically ranges between 2 and 3, which makes them significantly acidic. While they are the highest sources of vitamin C and antioxidants, their acidity can irritate the stomach lining and worsen acid reflux or heartburn.

Limiting citrus intake or diluting the juice with water can help reduce symptoms for people sensitive to acidity. Even though they are acidic, they still provide health benefits such as enhancing immunity and stimulating collagen production for healthy skin.

2. Tomatoes

Tomatoes contain malic and citric acids, making them an acidic food with a pH between 4.3 and 4.9. Though tomatoes are packed with nutrients like vitamins A, C, and lycopene, their acidity can trigger acid reflux in sensitive individuals. Tomato-based products like sauces, ketchup, and soups can increase the acidic content further, causing digestive discomfort.

To minimise their impact on acidity, pairing tomatoes with alkaline foods like leafy greens can help neutralise the effects. Despite their acidity, tomatoes remain heart-healthy due to their antioxidant properties.

3. Vinegar

Vinegar, mainly white and apple cider vinegar, has an acidic pH of around 2 to 3. It contains acetic acid, which can stimulate acid production in the stomach, leading to discomfort for those prone to acid reflux or indigestion. Although small amounts of vinegar, especially apple cider vinegar, are sometimes used to aid digestion, excessive consumption can worsen acid-related symptoms.

It is commonly found in salad dressings, pickled foods, and marinades. Moderation is key to balancing the benefits of vinegar, such as improved blood sugar control, while avoiding its acidic side effects.

4. Coffee

Coffee is considered slightly acidic, with a pH of 4.85 to 5.10. The acidity in coffee comes from various organic acids like chlorogenic acid. This can stimulate the production of stomach acid, leading to heartburn or acid reflux, mainly when consumed on an empty stomach.

Despite its acidity, coffee is a food high in antioxidants and provides many health benefits, such as improved mental alertness and a reduced risk of certain chronic diseases. However, for those sensitive to acidity, switching to low-acid coffee blends or adding a splash of milk can reduce its acidic impact.

5. Carbonated Beverages

Carbonated beverages like soda and sparkling water are acidic due to carbonic acid, which forms when carbon dioxide is dissolved in water. These drinks typically have a pH between 3 and 4. The acidity can erode tooth enamel and contribute to acid reflux. 

Additionally, sodas are often loaded with sugar or artificial sweeteners, increasing their negative impact on digestion and overall health. Drinking these drinks on a regular basis might cause gastrointestinal problems like gas, bloating, and increased acid production. Opting for still water or herbal teas can reduce acidity and improve hydration.

6. Chocolate

Chocolate, incredibly dark chocolate, contains acidic compounds like theobromine and caffeine, with a pH between 5.5 and 6. While chocolate has antioxidant properties and offers mood-boosting benefits, it can relax the lower oesophagal sphincter (LES), allowing stomach acid to flow back into the oesophagus. This can trigger acid reflux or heartburn.

People prone to acid reflux should limit their chocolate intake to avoid digestive discomfort. Opting for less acidic, milk-based chocolate or consuming it in small amounts can minimise its acidic effects while still enjoying its flavour.

7. Alcohol

Alcoholic beverages like wine, beer, and spirits are acidic, with pH levels between 3 and 4 for wine and around 4 for beer. Alcohol causes the lower LES to relax, leading to an increased likelihood of stomach acid flowing into the oesophagus, resulting in acid reflux and heartburn.

Additionally, alcohol irritates the stomach lining, increasing acid production and the risk of gastritis and other common gut problems over time. To reduce the impact of alcohol on acidity, it’s advisable to limit intake, avoid mixing it with acidic beverages like citrus juice, and drink plenty of water between alcoholic drinks.

8. Fried Foods

Fried foods like French fries, fried chicken, and onion rings are acidic and high in unhealthy fats. These lipids increase the formation of stomach acid and slow down digestion, allowing food to remain in the stomach for longer. The frying process also produces trans fats, which can worsen heartburn and cause inflammation in the digestive tract. Limiting fried food consumption can improve digestive health and reduce acid-related symptoms. Instead, use baking, grilling, or steaming foods to lower acidity.

9. Processed Meats

Processed meats like sausages and hot dogs are acidic due to preservatives like nitrates and sodium. These meats have a pH ranging between 5 and 6. Regular consumption can lead to an acidic environment in the stomach, triggering acid reflux and heartburn.

Additionally, processed meats are high in unhealthy fats and salt, which can slow digestion and increase stomach acid production. Replacing processed meats with lean proteins like chicken, turkey, or plant-based options can reduce acidity and improve overall health, as processed meats have also been linked to increased risks of chronic diseases.

10. Spicy Foods

Spicy foods, especially those made with chilli peppers, contain capsaicin, which can irritate the stomach lining and increase stomach acid production. This often leads to heartburn and acid reflux, particularly in people with sensitive digestive systems. Spices like black pepper, cayenne, and paprika have a low pH, adding to the acidity of meals.

While spices can have health benefits like boosting metabolism, it’s best to consume them in moderation if prone to acid reflux. Choosing milder alternatives or balancing spicy dishes with alkaline foods can help neutralise their acidic effects.

What Foods Reduce Acidity Quickly?

Some foods can neutralise stomach acid and alleviate symptoms such as heartburn and acid reflux.

 

• Bananas: A great option, as they have a low acid content and act as a natural antacid by coating the stomach lining. Bananas are also a great constipation-relief foods. 

• Oatmeal: An excellent choice because it absorbs excess acid in the stomach and provides a slow release of energy, preventing further acid production.

• Ginger: Due to its inherent anti-inflammatory qualities, ginger helps calm the stomach and lessen discomfort caused by acid reflux. You can drink it as ginger tea or include it in food. ToneOp Care’s Turmeric, Ginger & Garlic Oil Capsules help boost immunity, maintain blood cholesterol and improve digestion.

• Almonds: They are alkaline-forming nuts that help neutralise stomach acid, while leafy greens like spinach and kale are low in acid and packed with essential nutrients that promote digestive health.

• Yoghurt: Its probiotics can also reduce acidity. These support healthy digestion and balance stomach acid levels. Moreover, eating watermelon and cucumbers with high water content can assist in diluting stomach acid and offering rapid relief from discomfort.

Which Foods Are Non-Acidic?

Non-acidic foods have a neutral or alkaline pH and do not contribute to acid buildup in the stomach. These foods provide a balanced pH and are easy on the digestive tract. Some of the best non-acidic foods include:

• Vegetables: Leafy greens like spinach, kale, and broccoli are low in acid and provide essential nutrients. Other non-acidic veggies include cucumbers, bell peppers, and zucchini. You can blend all the veggies together with Moringa Leaf Powder or Wheat Grass Powder to neutralise stomach acidity too. 

• Fruits: While citrus fruits are acidic, many fruits, such as bananas, melons, apples, papayas and avocados, are non-acidic and support digestion without causing reflux.

• Whole Grains: Because they generate an alkaline state, whole wheat, brown rice, and oats are great for lowering acidity.

• Lean Proteins: Chicken, turkey, and tofu are non-acidic protein options that won’t trigger acid reflux.

Dietitian’s Recommendation

As a dietitian, I suggest limiting acidic foods such as citrus fruits, tomatoes, vinegar, coffee, and carbonated beverages if you experience acid reflux or digestive issues. Instead, concentrate on foods with high alkaline content, like leafy greens, bananas, and whole grains. 

Consume a lot of water to reduce stomach acid concentration and opt for smaller, frequent meals to avoid overeating, which can exacerbate acidity.

Choose healthy proteins such as chicken or fish instead of processed meats. Refrain from eating close to bedtime since reclining right after eating can boost acid production, causing heartburn. 

Ensure your digestion is at its best by incorporating fibre and probiotics into your diet equally. Go for ToneOp Care’s Digest 360 tablets, a powerful blend of 12 enzymes that restore the balance of your digestive system. They aid food absorption and digestion and help get rid of acidity and bloating.
