It’s easy to assume the fruits with the most total fiber, like raspberries and blackberries, must also carry the most soluble fiber. They don’t. According to the National Heart, Lung, and Blood Institute, citrus fruits and pears lead, at about 2 grams of soluble fiber per medium fruit.
Prunes come next at 1.5 grams per quarter cup. Most other soluble fiber fruits, including apples, bananas, peaches and blackberries, land at about 1 gram per serving.
Soluble fiber in a sentence or two
Cleveland Clinic describes soluble fiber as fiber that dissolves in water and other body fluids, forming a gel like substance in your digestive tract. That gel slows fat absorption, helps lower cholesterol and blood sugar, and feeds helpful gut bacteria.
In fruit, much of that soluble fiber is pectin, the same substance that makes jam set. Harvard Health names apples, grapes, strawberries and citrus fruits as sources of pectin that help lower LDL cholesterol.
Soluble fiber fruits, ranked by serving
The NHLBI’s cholesterol guide is one of the few public sources that splits fruit fiber into soluble and total. Here’s its list, sorted by soluble fiber.
| Fruit | Serving | Soluble fiber | Total fiber | Soluble share |
|---|---|---|---|---|
| Orange or grapefruit | 1 medium | 2 g | 2 to 3 g | about 70 to 100% |
| Pear | 1 medium | 2 g | 4 g | 50% |
| Prunes | 1/4 cup | 1.5 g | 3 g | 50% |
| Nectarine | 1 medium | 1 g | 2 g | 50% |
| Peach | 1 medium | 1 g | 2 g | 50% |
| Plum | 1 medium | 1 g | 1.5 g | about 67% |
| Banana | 1 medium | 1 g | 3 g | about 33% |
| Apple | 1 medium | 1 g | 4 g | 25% |
| Blackberries | 1/2 cup | 1 g | 4 g | 25% |
Citrus comes out on top by share. By these figures, most to nearly all of an orange’s or grapefruit’s fiber is the soluble kind.
Pears match citrus on grams and add more total fiber on top. Prunes give the same 50% split in a small, easy portion.
Apples and blackberries are the surprise. Both carry plenty of total fiber, but only about a quarter of it is soluble.
Citrus, pears and prunes up close
Citrus fruits
Oranges and grapefruit pair a high soluble share with very few calories. The Dietary Guidelines list a medium orange at 73 calories and a whole grapefruit at 130, and Cleveland Clinic names citrus among its go to soluble fiber foods.
Eat the segments rather than drinking the juice, since the fiber sits in the fruit itself. A cup of mandarin sections adds about 3.5 grams of total fiber.
Pears
A medium pear gives 2 grams of soluble fiber by NHLBI’s count and 5.5 grams of total fiber by the Dietary Guidelines. That combination is hard to beat for one piece of fruit.
Prunes
Prunes pack 1.5 grams of soluble fiber into a quarter cup, which makes them one of the most compact options. They’re also easy to keep in a desk drawer or bag for days at a time.
Why berries don’t top the soluble list
The Dietary Guidelines for Americans rank raspberries and blackberries among the highest fiber fruits, at 8.0 and 7.6 grams per cup. That’s double what a medium orange provides.
Most of that berry fiber is insoluble, though. Cleveland Clinic lists berries among sources of insoluble fiber, the kind that adds bulk to stool, and NHLBI’s figures put blackberries at just 1 gram soluble out of 4 per half cup.
A West Suffolk NHS patient guide also groups berry fruits, along with cherries, grapes and kiwi, with the tougher insoluble fibers.
So berries are still excellent for total fiber and regularity. For soluble fiber specifically, citrus and pears do more per serving.
How total fiber compares
Soluble fiber is only one part of the picture. These are total fiber figures from the Dietary Guidelines for Americans, for the same fruits.
| Fruit | Serving | Total fiber | Calories |
|---|---|---|---|
| Raspberries | 1 cup | 8.0 g | 64 |
| Blackberries | 1 cup | 7.6 g | 62 |
| Pear | 1 medium | 5.5 g | 103 |
| Grapefruit | 1 fruit | 5.0 g | 130 |
| Apple, with skin | 1 medium | 4.8 g | 104 |
| Orange | 1 medium | 3.7 g | 73 |
| Banana | 1 medium | 3.2 g | 112 |
| Prunes | 1/4 cup | 3.1 g | 105 |
These totals run a little higher than NHLBI’s, since the two sources use different fruit sizes and methods. The ranking of soluble share stays useful either way.
Pears are the all rounder here. They sit near the top for total fiber and tie for the top spot on soluble fiber per fruit.

Skins, ripeness and cooking
Where the fiber sits in a fruit matters too. The West Suffolk NHS guide lists apples and pears without skins, ripe bananas and peeled stone fruit among soft, soluble fiber foods.
The guide treats the skin as the tougher part of these fruits, which is why it suggests peeling them when you want softer, soluble fiber. Leave the skin on when you want the most total fiber, since the Dietary Guidelines figure of 4.8 grams for an apple counts the skin.
The same guide notes that cooking fruit and choosing ripe produce raises the soluble content. Stewed apples, baked pears and ripe bananas are all gentle, soluble fiber options, and the guide lists green bananas with the insoluble foods.
What soluble fiber fruits do for gut health
Cleveland Clinic notes that soluble fiber feeds the beneficial bacteria in your gut. That’s one reason soluble fiber fruits pair so well with oats, beans and other soluble fiber foods.
Insoluble fiber has its own job. Cleveland Clinic explains that it absorbs fluid and binds with other material to form softer, bulkier stool, which helps prevent constipation and may lower the risk of hemorrhoids and diverticulitis.
Most whole fruits give you some of each. A mix of citrus and pears for soluble fiber, plus berries and apples with skins for insoluble fiber, covers both needs without much planning.
Canned, stewed and baked fruit
Fresh fruit isn’t the only route. The West Suffolk NHS guide lists tinned fruit, other than citrus, among its soluble fiber foods, along with stewed and baked apples.
That makes canned peaches, pears and plums a practical backup when fresh fruit runs low. Choose fruit packed in juice or water if you’re watching added sugar.
Cooked fruit also works well in breakfast. Stir stewed apples or chopped prunes into oatmeal and you’ve combined two soluble fiber sources in one bowl.
Soluble fiber fruits and cholesterol
Harvard Health explains that soluble fiber binds cholesterol and its building blocks in the digestive system, so they leave the body before reaching the bloodstream. It recommends at least 5 to 10 grams of soluble fiber a day within a total of 20 to 35 grams.
The NHLBI guide adds that raising soluble fiber by 5 to 10 grams a day has been linked with about a 5% drop in LDL cholesterol. UCSF Health notes that many experts suggest about a quarter of total fiber come from soluble sources, roughly 6 to 8 grams a day.
Fruit alone won’t get most people there, but it can cover a big share. Two or three soluble fiber fruits a day can supply 4 to 6 grams.
A day of fruit, counted for soluble fiber
Here’s how a fairly ordinary day could look if you lean on the top soluble fiber fruits, using NHLBI’s figures.
| When | Food | Soluble fiber |
|---|---|---|
| Breakfast | 1/2 cup cooked oatmeal with a sliced banana | 2 g |
| Lunch | 1 medium orange | 2 g |
| Afternoon | 1 medium pear | 2 g |
| Evening | 1/4 cup prunes | 1.5 g |
| Total | 7.5 g |
That adds up to about 7.5 grams of soluble fiber, comfortably inside the 5 to 10 gram range, with fruit doing most of the work.

A soluble fiber fruit checklist
- Keep oranges, grapefruit or mandarins on hand for an easy 2 gram snack.
- Choose pears often, since they score high on both soluble and total fiber.
- Add prunes to oatmeal, yogurt or a trail mix for 1.5 grams per quarter cup.
- Pick ripe bananas over green ones if soluble fiber is your goal.
- Try stewed apples or baked pears when you want something gentle on the gut.
- Keep berries in the mix for total fiber, even though their soluble share is lower.
Cleveland Clinic advises adding fiber gradually to avoid gas, pain and bloating, so build up one extra fruit at a time. If your gut likes a slow, steady approach, our guides walk you through it step by step.
A quick rule for choosing
If your main goal is lowering cholesterol, reach for citrus, pears and prunes first, since they give the most soluble fiber per serving. If your goal is regularity, add berries and apples with their skins for the extra insoluble fiber.
If you want both, a pear is the safest single pick. It ties for the most soluble fiber of any fruit on NHLBI’s list and carries some of the highest total fiber too.
Questions about soluble fiber fruits
Which fruit has the most soluble fiber?
Oranges, grapefruit and pears lead, with about 2 grams of soluble fiber per medium fruit, according to the NHLBI. Prunes follow at 1.5 grams per quarter cup.
Are apples high in soluble fiber?
Moderately. A medium apple has about 1 gram of soluble fiber out of roughly 4 grams total, and apples are a known source of pectin.
Do berries have soluble fiber?
Yes, but not much compared with their total. Half a cup of blackberries has about 1 gram soluble out of 4 grams total, since most berry fiber is insoluble.
Are bananas soluble or insoluble fiber?
Bananas have both. A medium banana has about 1 gram of soluble fiber out of 3 grams total, and ripe bananas lean more toward the soluble kind.
What fruit is best for lowering cholesterol?
Citrus fruits, pears, apples and other pectin rich fruits help most. Harvard Health names apples, grapes, strawberries and citrus as sources of pectin that lowers LDL.
Do prunes have soluble fiber?
Yes. A quarter cup of prunes has about 1.5 grams of soluble fiber, half of its 3 grams of total fiber.
Does peeling fruit change the fiber?
Yes. Peeling removes the skin, which NHS guidance treats as the tougher, less soluble part, so you keep a softer fiber but lose some total fiber.
