Non-citrus fruits are any fruits that don’t belong to the citrus genus, which includes oranges, lemons, limes, grapefruits, and tangerines. That leaves a huge range of fruits, from apples and bananas to mangoes, kiwis, and melons. If you’re avoiding citrus because of acid reflux, an allergy, or simply want to know what else is out there, most of the fruit aisle qualifies.
What Makes a Fruit “Citrus”
Citrus fruits all belong to the genus Citrus in the family Rutaceae. They share a few traits: a thick rind, segmented flesh, and high levels of citric acid. Oranges, lemons, limes, grapefruits, tangerines, kumquats, and pomelos are the main members of this family. Everything outside that botanical group is non-citrus, even if it tastes tart or contains vitamin C.
Pome Fruits: Apples, Pears, and Quince
Pome fruits have a fleshy outer layer surrounding a central core with seeds. Apples and pears are the most common examples, but quince, loquat, and medlar also belong to this group. All pome fruits are members of the Rosaceae (rose) family, placing them far from citrus botanically.
Apples and pears store well at cool temperatures and are available year-round in most grocery stores. Their pH ranges from about 3.3 to 4.6, making them mildly acidic but generally gentler on the stomach than citrus. Pears in particular are a go-to for people with sensitive digestion because of their soluble fiber content.
Stone Fruits
Stone fruits, also called drupes, have soft flesh surrounding a hard pit. This category includes peaches, plums, cherries, apricots, mangoes, and lychees. Most stone fruits peak in summer, though mangoes and lychees follow tropical growing seasons.
Peaches are loaded with plant pigments called carotenoids that give them their color and act as antioxidants. The skin of a peach can contain up to 27 times more antioxidants than the flesh, so eating the peel is worth it. Cherries may help improve sleep, regulate blood sugar, and reduce post-exercise muscle soreness. Plums, especially in their dried form as prunes, support bone density and digestive regularity. Apricots are particularly rich in beta carotene, which your body converts into vitamin A.
Mangoes deserve a special mention as a tropical stone fruit packed with fiber that supports digestion, along with vitamins C and E. Lychees are another tropical drupe, notably high in vitamin C and antioxidant compounds.
Berries
Strawberries, blueberries, raspberries, blackberries, and cranberries are all non-citrus. Strawberries are one of the best non-citrus sources of vitamin C: a half cup of sliced fresh strawberries provides about 49 mg, covering 54% of your daily needs. For comparison, a medium kiwi delivers 64 mg (71% of the daily value), rivaling most citrus fruits.
Blueberries tend to be more acidic than you might expect, with a pH between 3.1 and 3.3. Raspberries and blackberries fall in a similar range. If you’re avoiding acidic foods specifically, berries aren’t always the mildest option, but they’re nutritionally dense and rich in fiber.
Tropical Fruits
The tropics produce some of the most flavorful non-citrus fruits. Bananas are high in carbohydrates and potassium, making them a quick energy source. Pineapple contains a natural enzyme called bromelain that aids protein digestion. Papaya has a similar enzyme called papain. Guava is a powerhouse of vitamins A, B, and C. Barbados cherry, a lesser-known tropical fruit, is exceptionally high in vitamin C.
Pomegranates, which belong to the family Punicaceae, are botanically unrelated to citrus despite their tangy flavor and jewel-like seeds. They are quite acidic, with a pH between 2.93 and 3.20, actually more acidic than many citrus fruits. Dates stand out as one of the most calorie-dense fruits, with about 54% sugar and 7% protein.
Melons
Watermelon, cantaloupe, and honeydew are among the least acidic fruits you can eat. Cantaloupe and honeydew both have a pH between 6.0 and 6.7, making them nearly neutral. Watermelon falls around 5.2 to 5.6. This makes melons a particularly good choice if you’re dealing with acid reflux. University Hospitals specifically lists watermelon, cantaloupe, and honeydew as some of the best fruits for people managing GERD.
Melons are also extremely hydrating because of their high water content. They tend to be lower in fiber than most other fruits but make up for it with volume and refreshment.
Non-Citrus Vitamin C Sources
One reason people search for non-citrus fruits is to find alternative sources of vitamin C. Citrus has a reputation as the top source, but several non-citrus fruits match or exceed it. A single medium kiwi provides 64 mg of vitamin C. Guava is even higher. A half cup of strawberries gets you more than halfway to your daily requirement. Lychees, mangoes, and pineapple all contribute meaningful amounts as well.
If your goal is to hit your vitamin C intake without citrus, combining kiwis, strawberries, and guava throughout the week will more than cover it.
Acidity Levels Compared to Citrus
Many people avoid citrus because of its acidity, so it helps to know where non-citrus fruits fall on the pH scale. Lower numbers mean more acid.
- Most acidic non-citrus fruits (pH 2.7 to 3.4): Concord grapes, plums, pomegranates, blueberries, and rhubarb. These are comparable to or even more acidic than some citrus.
- Moderately acidic (pH 3.3 to 4.5): Apples, peaches, pears, cherries, strawberries, mangoes, and pineapple. Most common fruits land in this range.
- Low acid (pH 4.5 and above): Bananas (4.5 to 5.2), watermelon (5.2 to 5.6), papaya (5.2 to 6.0), cantaloupe (6.1 to 6.6), honeydew (6.0 to 6.7), and avocados (6.3 to 6.6).
If you’re specifically looking for low-acid alternatives to citrus, melons, bananas, papaya, and avocados are your best bets. Switching from oranges to pomegranates or grapes won’t reduce the acidity in your diet.
