The Main Culprits: Highly Acidic Fruits
For many individuals with acid reflux, fruits with high acidity are the primary cause of discomfort. The low pH of these fruits can irritate the esophagus and trigger heartburn. Consuming them, especially on an empty stomach, can lead to a flare-up of symptoms.
Citrus Fruits
This category is perhaps the most well-known trigger for acid reflux due to its high citric acid content. The acid can weaken the lower esophageal sphincter (LES), the valve that separates the stomach from the esophagus, allowing stomach acid to flow upward.
The most problematic citrus fruits include:
- Lemons and limes
- Grapefruits
- Oranges
- Tangerines
Pineapple
With a pH ranging from 3.2 to 4.0, pineapple is a highly acidic fruit that can cause discomfort for many reflux sufferers. Its natural enzymes and high acid content can be particularly irritating to a sensitive esophagus.
Tomatoes
Although often used as a vegetable in cooking, tomatoes are botanically a fruit and are notoriously high in both citric and malic acids. This makes them a frequent trigger for heartburn, whether consumed fresh, in sauces, or in juice. Avoiding tomato-based products like marinara sauce, ketchup, and salsa is often recommended for managing acid reflux.
Beyond Citrus: Other Potential Fruit Triggers
While citrus fruits are the most common offenders, other fruits can also cause issues depending on an individual's sensitivity. The level of ripeness and how the fruit is prepared can also play a role.
Plums and Grapes
Certain varieties of plums and grapes are more acidic than others. For example, blue plums have a pH between 2.80 and 3.40, and grapes can range from 2.90 to 3.82. For some, even moderately acidic fruits like these can cause problems.
Blueberries
Despite their many health benefits, blueberries have a pH between 3.12 and 3.33, placing them in the acidic range. Some individuals with sensitive stomachs may find that blueberries or blueberry juice trigger their symptoms.
Green Apples vs. Red Apples
Interestingly, not all apples are created equal when it comes to acid reflux. Red apples, particularly sweeter varieties, tend to have a lower acid content and are often well-tolerated. Green apples, such as Granny Smiths, are significantly more acidic and can worsen symptoms for many people.
Fruit Juices and Dried Fruit
Fruit juices are often more concentrated and acidic than the whole fruit, which is why experts recommend avoiding citrus juices, such as orange and grapefruit juice, entirely if you have reflux. Similarly, dried fruits, like raisins, are concentrated in sugars and can be a reflux trigger for some.
A Comparison of Fruits for Acid Reflux
This table provides a quick reference for which fruits to approach with caution and which are generally safer for those with acid reflux.
| Fruit | Acidity Level (pH) | Reflux Effect |
|---|---|---|
| Lemons/Limes | Very High (2.0-2.8) | Trigger |
| Grapefruits | Very High (3.0-3.75) | Trigger |
| Pineapple | High (3.2-4.0) | Trigger |
| Tomatoes | High (4.3-4.9) | Trigger |
| Oranges | High (3.69-4.34) | Trigger |
| Green Apples | Moderate to High (3.3-4.0) | Potential Trigger |
| Strawberries | Moderate (3.0-3.9) | Potential Trigger |
| Bananas | Low/Alkaline (>5.0) | Soothing/Beneficial |
| Melons (e.g., Cantaloupe) | Low/Alkaline (>6.0) | Soothing/Beneficial |
| Red Apples | Low/Alkaline (>4.0) | Soothing/Beneficial |
Tips for Enjoying Fruit with Acid Reflux
Eliminating all fruit from your diet is unnecessary and can deprive you of essential vitamins and fiber. The key is to make smart choices and listen to your body.
A list of strategies includes:
- Choose Low-Acid Varieties: Opt for alkaline and low-acid fruits like bananas, melons, pears, and avocados.
- Eat in Moderation: If a moderately acidic fruit, like a sweet red apple, doesn't bother you, enjoy it in small portions.
- Avoid Fruit Juices: Consume whole fruit instead of juice, as juice is more concentrated and acidic. Using a straw can also help limit direct contact with your teeth and esophagus.
- Pair with Alkaline Foods: Eating fruit with other alkaline foods, like yogurt or oatmeal, can help buffer the acidity.
- Time Your Intake: Avoid eating fruit close to bedtime, as lying down can worsen reflux symptoms.
- Keep a Food Diary: Tracking your food intake can help you identify your specific triggers, as individual sensitivities vary.

Conclusion
Understanding what fruits are bad for acid reflux is a key part of managing your symptoms through diet. While highly acidic fruits like citrus, pineapple, and tomatoes are frequent triggers, not all fruits are off-limits. By opting for lower-acid alternatives like bananas, melons, and red apples, and paying attention to your body's reactions, you can enjoy the nutritional benefits of fruit without experiencing painful heartburn. Experiment with portion sizes and timing, and don't hesitate to consult a healthcare professional if symptoms persist.
Recommended Fruits to Eat
- Melons: Cantaloupe, honeydew, and watermelon are all low-acid and safe choices for many reflux sufferers.
- Bananas: Naturally alkaline, bananas can help neutralize stomach acid and provide a protective coating for the esophagus.
- Pears: Sweet pears have a very low acid content and are generally well-tolerated.
- Avocados: This creamy fruit is low in acidity and offers healthy fats.
- Apples: Choose sweet, ripe red apples over more acidic green varieties.
Remember, your body's tolerance can change, so a food diary is a valuable tool for monitoring your unique triggers.
