Best Dried Fruits for Constipation, Ranked by Real Data
2026-09-05 · By the Diet for Constipation data editorial team · 1,272 words
The best dried fruits for constipation are the ones that keep their fiber after the water leaves — and our database shows that is not all of them. Drying concentrates everything: fiber, sugar, calories. Rank ten common dried fruits on fiber per 100 grams and the spread runs from 9.8 g down to 4.5 g — a two-fold gap that most shoppers never see, because the packages all show the same sunny orchard imagery. This ranking uses our own rated database (USDA source data), with the per-serving math and the traps called out honestly.
The ranking, by fiber per 100 grams
| Rank · Fruit | Fiber / 100 g | Typical serving | Fiber per serving |
|---|---|---|---|
| 1. Dried figs | 9.8 g | ≈ 3 figs | ≈ 2.9 g — the class leader |
| 2. Dried apples | 8.7 g | 86 g pack | ≈ 7.5 g |
| 3. Dried peaches | 8.2 g | 160 g cup | ≈ 13.1 g |
| 4. Deglet noor dates | 8.0 g | 1 date | ≈ 0.8 g — doses like pills |
| 5. Dried blueberries (sweetened) | 7.5 g | 40 g box | ≈ 3.0 g — plus 27 g sugar |
| 6. Dried apricots | 7.3 g | 130 g cup | ≈ 9.5 g |
| 7. Medjool dates | 6.7 g | 1 date (24 g) | ≈ 1.6 g per date |
| 8. Dried jujube | 6.0 g | 100 g | ≈ 6.0 g |
| 9. Dried cranberries (sweetened) | 5.3 g | 40 g box | ≈ 2.1 g — plus 29 g sugar |
| 10. Dark raisins | 4.5 g | 145 g cup | ≈ 6.5 g |

Why figs and dates lead the practical ranking
Dried figs win on every axis at once: the highest fiber density in the class (9.8 g per 100 g), a built-in portion control problem solved by the fruit itself — three figs are three figs — and a chew that makes people slow down. Deglet noor dates dose like pills: 0.8 g of fiber per date, easy to count, easy to build a habit around. Two medjool dates give 3.2 g alongside a caramel-like sweetness that makes them the easiest sell at a breakfast table.
Dried apples and peaches rank high per 100 grams but their real-world servings are heavier — a full cup of dried peach halves delivers around 13 g of fiber, more than half of most adults' daily target in one sitting. That is a feature if you spread it across the day and a problem if you eat the whole cup between meals without water.
Prunes: not the top of the raw table, and it does not matter
Sharp-eyed readers will notice prunes are absent from the raw fiber ranking — their database entry carries a data gap in our library. Our dedicated prunes verdict covers the full picture: 7.1 g of fiber per 100 g, plus roughly 14.7 g of sorbitol, a sugar alcohol that holds water into the stool. That combination is why prunes, not figs, carry the clinical crown: in a randomized crossover trial, 40 adults ate 100 g of prunes a day (6 g of fiber) or psyllium at the identical fiber dose for three weeks each (PMID 21323688). Complete spontaneous bowel movements rose from about 1.7 to 3.5 per week on prunes, against 1.6 to 2.8 on psyllium, and stool consistency improved significantly more. Same fiber dose, different outcome — the credit goes to the sorbitol and roughly 184 mg of polyphenols per 100 g that ride along with the fiber.
The ranking above is a fiber-density ranking. Prunes are a whole-mechanism ranking — fiber plus osmotic payload — and that is why they keep the crown despite finishing mid-table on raw fiber.
The sugar trap in the berry aisle
Two entries in the table deserve their own warning. Dried blueberries and dried cranberries almost never reach the shelf unsweetened — cranberries are too tart to sell raw. The sweetened versions carry 67.5 g and 72.6 g of sugar per 100 g respectively. A 40-gram box that feels like a healthy handful delivers around 3 g of fiber and 27–29 g of sugar — the sugar load of a candy bar wearing a fruit costume. Our granola bar verdict covers the same mechanism from the snack side: concentrated sweetness that rides along with a modest fiber number.
The same logic disqualifies the juice shelf. Prune juice delivers 1.0 g of fiber per 32 g serving — the fiber stayed in the press. Juice belongs to the sorbitol story, not the fiber story; if fiber is the goal, the whole dried fruit is the object.
How to actually use dried fruit for the fiber target
Count per serving, not per package. The difference between the best and worst entry in this ranking is two-fold per 100 grams, but the practical gap per handful is wider still, because serving sizes vary from 24 g (one medjool date) to 160 g (a cup of dried peaches). One honest handful of figs or apricots adds 3–5 g toward the 25–30 g daily target; the same handful of sweetened cranberries adds 2 g of fiber and a dessert's worth of sugar.
Pair them with water. Dried fruit works partly by absorbing water downstream; eaten dry and in bulk, concentrated fiber can firm up before it softens. A glass of water alongside is not optional etiquette — it is part of the mechanism.
Spread the dose. Two or three dates at breakfast, figs at lunch, apricots in the afternoon beats one large dried-fruit session, for comfort as much as effect. And for the full board beyond dried fruit, the Best Foods for Constipation master list ranks every green-rated food in the library.

FAQ — quick answers
Which dried fruit has the most fiber?
Dried figs lead our ranking at 9.8 g of fiber per 100 g, followed by dried apples (8.7 g), dried peaches (8.2 g) and deglet noor dates (8.0 g). Per typical serving, a cup of dried peaches delivers the most — about 13 g.
Are dried fruits as good as fresh fruit for constipation?
Per 100 grams, dried fruit carries roughly three to four times the fiber of the fresh original — but also the sugar and calories. Per real-world serving the totals even out. Dried fruit is the denser, more portable option; fresh fruit brings water volume. Both count toward the daily fiber target.
How many prunes should I eat per day?
The clinical trial behind our prunes verdict used 100 g per day — roughly 9 to 10 prunes, or 6 g of fiber. Many people do well on less. Start with 3 or 4 and adjust; the sorbitol payload means the effect arrives ahead of the fiber math.
Are dried cranberries and blueberries good for constipation?
Weaker than they look. The shelf versions are almost always sweetened — 67.5 g of sugar per 100 g for blueberries and 72.6 g for cranberries in our database. A 40 g box adds around 2–3 g of fiber alongside 27–29 g of sugar. Unsweetened forms are rare; raisins, figs and apricots do the same job with less sugar.
