Many people file passion fruit under drinks: something that flavors juice, cocktails and sorbet. That picture misses the best part, because the whole pulp is one of the most fiber dense fruits in USDA’s database.
Passion fruit fiber comes to 10.4 grams per 100 grams of pulp, and a quarter cup gives about 6.1 grams for just 57 calories. Strain out the seeds for juice and almost all of it disappears.
Passion fruit fiber, scoop by scoop
These values come from USDA FoodData Central’s record for purple passion fruit, also sold as granadilla or maracuya. The edible part is the jelly-coated seeds scooped from inside the wrinkled shell.
| Amount of pulp | Calories | Fiber | % Daily Value | Total sugars |
|---|---|---|---|---|
| 2 tablespoons (about 30 g) | 29 | 3.1 g | 11% | 3.3 g |
| 1/4 cup (59 g) | 57 | 6.1 g | 22% | 6.6 g |
| 100 grams | 97 | 10.4 g | 37% | 11.2 g |
| 1 cup (236 g) | 229 | 24.5 g | 88% | 26.4 g |
The FDA sets the fiber Daily Value at 28 grams, and a food with 20% or more per serving counts as high in fiber. A quarter cup of pulp clears that bar on its own.
A full cup would hand you almost a day’s worth. Few people eat that much in one sitting, which is why the quarter cup listed in the Dietary Guidelines tables is the more useful number.
Sugar is the other surprise. Passion fruit pulp carries roughly one gram of fiber for every gram of sugar. On the FDA’s fruit list, a banana manages about 0.16 and a large apple 0.2.
Why juice and strained pulp lose the fiber
Juice, frozen seedless pulp and nectar are common ways to buy passion fruit. The numbers below show what happens once the seeds are strained out:
| Form | Serving | Calories | Fiber | Total sugars |
|---|---|---|---|---|
| Whole pulp with seeds | 1 cup (236 g) | 229 | 24.5 g | 26.4 g |
| Purple passion fruit juice | 1 cup (247 g) | 126 | 0.5 g | 33.1 g |
| Yellow passion fruit juice | 1 cup (247 g) | 148 | 0.5 g | 35.2 g |
| Frozen strained pulp (Mama Lycha, as submitted to USDA) | 80 ml | 50 | 0 g | 12 g |
Cup for cup, the juice keeps about 2% of the fiber while its sugar actually rises. With nothing left to slow it down, a glass of passion fruit juice behaves much more like any other fruit juice than like the fruit.
Harvard’s Nutrition Source makes the same general point for all fruit: eat whole fruits instead of drinking fruit juices. With passion fruit the gap is unusually wide, because the part that gets strained away is where the fiber lives.
The frozen pulp packs sold in many grocery freezers deserve a closer look too. The one in USDA’s branded database is labeled as pulp but lists 0 grams of fiber, so check whether a package says seedless, strained or with seeds before counting on it.
Purple or yellow: does the color matter?
Grocery stores sell two main types: smaller purple passion fruit and larger yellow ones. USDA’s whole pulp record covers the purple kind, so that’s where the fiber figures above come from.
USDA does list juice for both. A cup of yellow juice has about 148 calories and 45 mg of vitamin C, while purple juice has about 126 calories and 74 mg of vitamin C. Both keep the same half gram of fiber, so for fiber the real choice is pulp or juice, not purple or yellow.
Passion fruit next to other tropical picks
If you lean on tropical fruit, passion fruit is the standout for fiber per calorie. This comparison uses USDA, FDA and Dietary Guidelines values:
| Fruit and serving | Calories | Fiber | Fiber per 100 calories |
|---|---|---|---|
| Passion fruit pulp, 1/4 cup | 57 | 6.1 g | 10.7 g |
| Guava, 1 cup | 112 | 8.9 g | 7.9 g |
| Kiwifruit, 2 medium (148 g) | 90 | 4 g | 4.4 g |
| Papaya, 1 cup cubes (145 g) | 62 | 2.5 g | 4.0 g |
| Banana, 1 medium (126 g) | 110 | 3 g | 2.7 g |
| Dragon fruit, 1 cup (180 g) | 122 | 3.2 g | 2.6 g |
| Pineapple, 2 slices (112 g) | 50 | 1 g | 2.0 g |
Passion fruit gives about four times the fiber of a banana for the same calories, and five times that of pineapple. Raspberries do edge past it, at about 12.5 grams per 100 calories in the Dietary Guidelines table.
Guava gives more fiber per serving, mainly because people eat a full cup of it. Passion fruit wins when you’re working with a small spoonful.

The seeds, bowel health and regularity
The crunchy black seeds are what make passion fruit such a dense fiber rich fruit. They’re edible, and eating them is the whole point if fiber is your goal.
Cleveland Clinic recommends 18 to 30 grams of fiber a day to help prevent constipation, along with 2 to 4 extra glasses of water. A quarter cup of passion fruit pulp covers about a fifth to a third of that range.
Because the fiber is so concentrated, that water advice applies even to a small scoop. Pair your passion fruit with a drink rather than eating it on its own.
Go slowly if your current diet is low in fiber. Harvard advises raising intake gradually and drinking plenty of fluids, and a fruit that delivers 6 grams in a few spoonfuls is an easy place to overshoot.

Passionfruit nutrition beyond fiber
Per cup of pulp (236 grams), USDA lists more than just fiber. The numbers are big because a cup is a generous amount:
- Vitamin C: about 71 mg, roughly 79% of the 90 mg Daily Value.
- Iron: about 3.8 mg, roughly 21% of the 18 mg Daily Value.
- Potassium: about 821 mg, roughly 17% of the Daily Value.
- Magnesium: about 68 mg, roughly 16% of the Daily Value.
- Vitamin A: about 151 micrograms RAE, roughly 17% of the Daily Value.
- Protein: about 5.2 grams.
Scale those down by four for a realistic quarter cup. That portion still gives about 18 mg of vitamin C and nearly 1 mg of iron, a decent bonus for 57 calories.
Fiber in a tropical fruit bowl
Say you build a weekend breakfast bowl around a tropical diet theme: a cup of papaya cubes and two slices of pineapple. Based on USDA and FDA data, that comes to about 3.5 grams of fiber and 112 calories.
Spoon a quarter cup of passion fruit pulp over the top and the bowl jumps to about 9.6 grams, or 34% of the Daily Value. The smallest ingredient in the bowl now supplies almost two thirds of its fiber.
Add a spoonful of plain yogurt or a sprinkle of nuts and you have a breakfast with staying power. The pulp also works as a sauce, so you don’t need a sweetened dressing.

Scooping and serving the pulp
Passion fruit is ready to eat when the shell feels heavy for its size and starts to wrinkle. Cut it in half across the middle and scoop the pulp out with a teaspoon.
The flavor is tart and fragrant, so a little goes a long way. Spoon it over plain yogurt, overnight oats or chia pudding, or stir it into sparkling water for a drink that keeps its seeds.
If you have more fruit than you can eat, scoop the pulp into an ice cube tray and freeze it, seeds and all, for ready portions of about 2 tablespoons each.
A quick passion fruit fiber checklist
Use these points when shopping and serving:
- Buy whole fruit or pulp that keeps its seeds. Seedless and strained products lose nearly all the fiber.
- Read the fiber line on frozen pulp. A pack that shows 0 grams is basically juice in a block.
- Treat juice and nectar as treats, not fruit servings. A cup of juice has under half a gram of fiber and more than 30 grams of sugar.
- Start with 2 tablespoons if you’re new to fiber dense foods, then build toward a quarter cup.
- Drink a glass of water alongside, especially on days you eat several high fiber foods.
How to choose: pulp, juice or both
If fiber is the reason you’re buying passion fruit, eat the pulp with its seeds and count on about 6 grams per quarter cup. That small scoop does more for your fiber total than most whole fruits.
If you only want the flavor in a drink or dessert, juice or strained pulp is fine. Just count it as a sweet extra rather than fruit. And if you want both, stir a spoonful of seedy pulp into sparkling water or yogurt so the tart flavor and the fiber arrive together.
Passion fruit fiber: what people ask
Is passion fruit high in fiber?
Yes. A quarter cup of pulp has about 6.1 grams of fiber, or 22% of the Daily Value, which makes it a high fiber food by FDA standards.
Should you eat passion fruit seeds?
Yes, if you want the fiber. The seeds are edible, and USDA data shows strained juice keeps only about half a gram of fiber per cup compared with 24.5 grams in the whole pulp.
Does passion fruit juice have fiber?
Very little. A cup of purple or yellow passion fruit juice has about 0.5 grams of fiber and 33 to 35 grams of sugar.
Is passion fruit good for constipation?
It can help as part of your daily fiber. Cleveland Clinic suggests 18 to 30 grams of fiber a day plus extra water, and a quarter cup of pulp supplies about 6 grams of that.
How much passion fruit can you eat in a day?
There’s no set limit, but a quarter cup of pulp is a practical serving. If you eat little fiber now, start with about 2 tablespoons and increase gradually.
Which has more fiber, passion fruit or guava?
Per serving, guava, at 8.9 grams per cup. Per calorie, passion fruit wins with about 10.7 grams per 100 calories against 7.9 for guava.
Does frozen passion fruit pulp have fiber?
Only if it keeps the seeds. One frozen strained pulp in USDA’s branded database lists 0 grams of fiber, so check the label.
