What are low acid fruit juices?

January 9, 2026 •

According to Everyday Health, a pH below 7 is considered acidic, meaning all fruit juice falls somewhere on the acidic spectrum. What are low acid fruit juices are those made from fruits with a higher-than-average pH, making them gentler on sensitive digestive systems and teeth.

Quick Summary

Low acid fruit juices are made from fruits with higher pH levels, offering a gentler alternative for individuals with sensitive stomachs or acid reflux. Specific fruits, like melon and pear, are excellent choices for their lower acidity. Understanding the pH scale helps in selecting the best juices for digestive comfort.

Key Points

Acidity and pH Scale: Low acid fruit juices are made from fruits with a higher pH value, typically above 3.5, making them less irritating to sensitive digestive systems.
Gentle on the Stomach: These juices can help alleviate symptoms of acid reflux, GERD, and general indigestion by being less irritating to the stomach lining and esophagus.
Recommended Juices: Excellent low acid choices include melon (watermelon, cantaloupe), pear, and ripe banana juice or smoothies.
Smoothie Alternative: For added fiber and to further reduce acidity, making smoothies with low acid fruits and an alkaline base like almond milk is recommended.
DIY Juicing: Preparing low acid juices at home allows for control over ingredients, avoiding added sugars and preservatives that can worsen gastric issues.
High vs. Low Acidity: High acid juices (e.g., citrus) are more tart and can cause dental enamel erosion, whereas low acid options are milder and kinder to teeth.

Understanding Acidity in Juices

To understand what are low acid fruit juices, you must first grasp the concept of the pH scale. This scale measures acidity and alkalinity from 0 to 14, with 7 being neutral. Anything below 7 is acidic, and anything above is alkaline. While all fruit juices are acidic to some degree, those derived from fruits with a higher pH value are considered 'low acid' because they are less likely to trigger symptoms like heartburn or acid reflux. The acidity is caused by naturally occurring acids like citric and malic acid. For instance, highly acidic orange juice has a pH of 3.3-4.2, whereas a pear's pH ranges from 3.5-4.6, making it a better low-acid option.

The Health Benefits of Opting for Low Acid Options

Choosing low acid fruit juices offers several benefits, especially for those with digestive sensitivities. These benefits include:

Relief from Acid Reflux and GERD: Highly acidic beverages can irritate the esophagus and stomach lining, worsening symptoms of GERD. Low acid juices bypass this irritation, providing a soothing alternative.
Support for Sensitive Teeth: The high acid content in many fruit juices can erode tooth enamel over time. Juices with a lower pH are less corrosive and therefore kinder to sensitive teeth.
Improved Digestion: Some low acid fruits, like bananas, contain alkaline properties and natural enzymes that can aid in digestion and help balance stomach acid.
Rich in Nutrients: Juicing low acid fruits does not mean sacrificing vitamins and minerals. Options like melon juice are excellent sources of hydration and essential nutrients.

Popular Low Acid Fruit Juice Choices

Melon Juice

Melon juices, such as watermelon, cantaloupe, and honeydew, are known for their alkaline properties and high water content. This makes them an excellent, refreshing choice for those needing to reduce acidity. For a simple recipe, blend cubed melon with a splash of water until smooth.

Pear Juice

Pears generally have one of the highest pH levels among common fruits, making pear juice a superb low acid option. It has a gentle sweetness and is beneficial for digestive health. For best results, use ripe, peeled pears when juicing.

Apple Juice (With Caution)

While apples are generally lower in acid than citrus, their pH can still be moderately low. Ripe, sweet varieties are preferable to tart ones. Some sources suggest apples contain alkaline minerals that can help neutralize stomach acid. Always opt for natural, unsweetened apple juice and monitor your body's reaction.

Smoothies Instead of Juices

For maximum fiber and a further reduction in acidity, smoothies are often recommended. Combining low acid fruits like banana and melon with an alkaline base such as almond milk or low-fat plain yogurt creates a creamy, gut-friendly beverage that is easy to digest.

How to Prepare Low Acid Fruit Juices at Home

Making your own low acid juice ensures you control the ingredients, avoiding added sugars and preservatives that can exacerbate gastric issues. Here's how to create a simple melon blend:

Select ripe fruit: Choose a ripe melon (cantaloupe or honeydew) for the highest pH and sweetest flavor.
Chop and combine: Cube the melon and place it into a blender. Add a small amount of water to help it blend, if necessary.
Blend until smooth: Process until the mixture is a smooth liquid.
Strain if desired: For a pulp-free juice, strain the liquid through a fine-mesh sieve or nut milk bag.
Serve immediately: Pour into a glass and enjoy. Can be stored in the refrigerator for a short period.

Low Acid vs. High Acid Juices: A Comparison


Feature	Low Acid Juices (e.g., Melon, Pear)	High Acid Juices (e.g., Orange, Grapefruit)
pH Level	Generally higher (closer to 7), ranging from 3.5 to over 4.5.	Generally lower (more acidic), ranging from 2.0 to 4.2.
Taste Profile	Milder, sweeter, and less tangy.	More tart, sour, and sharp.
Digestive Impact	Less likely to trigger heartburn, acid reflux, or other gastric issues. Soothes the digestive tract.	Can irritate the esophagus and stomach lining, potentially worsening reflux symptoms.
Dental Health	Gentler on tooth enamel, reducing the risk of erosion.	Higher risk of causing enamel erosion over time.
Preparation	Often made from softer, pulpier fruits, sometimes better as smoothies.	Typically juiced easily, but can be too intense for sensitive individuals.

Conclusion

For those who experience digestive issues or have sensitive teeth, choosing what are low acid fruit juices can significantly improve comfort and overall health. By opting for juices from fruits like melons, pears, and ripe apples, you can enjoy a refreshing and nutritious beverage without the unwanted side effects associated with high acidity. Combining these juices with other alkaline ingredients in a smoothie can further enhance their benefits. Always listen to your body and introduce new juices gradually to see how you respond. By being mindful of your choices, you can enjoy the delicious benefits of fruit juice in a way that is kind to your digestive system.

Cautions and Considerations

When to Consult a Professional

While low acid fruit juices can help manage mild symptoms, they are not a substitute for medical advice. If you experience chronic or severe heartburn, GERD, or other digestive problems, it's essential to consult with a healthcare professional or a registered dietitian. They can provide a personalized plan tailored to your specific needs.

The Importance of Ripeness

The ripeness of a fruit is a significant factor in its acidity. Unripe fruits generally contain higher levels of acid and may cause discomfort, even in naturally low acid varieties. Always choose fruits that are fully ripe and soft, as this indicates a higher pH and better digestibility.
