Tropical fruit tends to get filed under sweet treats, the kind you eat for flavor rather than nutrition. Guava breaks that rule: one cup of fresh guava gives you 8.9 grams of fiber for 112 calories, more than a cup of raspberries.
That guava fiber content covers about 32% of the 28 gram Daily Value. The Dietary Guidelines for Americans rank guava third among all fruits by fiber per standard portion, behind only sapote and durian.
Guava fiber content by the numbers
USDA FoodData Central lab data for common raw guava shows how dense this fruit is:
| Amount | Calories | Fiber | % Daily Value | Total sugars |
|---|---|---|---|---|
| 100 grams | 68 | 5.4 g | 19% | 8.9 g |
| 1 cup (165 g) | 112 | 8.9 g | 32% | 14.7 g |
| 1/2 cup (about 83 g) | 56 | 4.5 g | 16% | 7.4 g |
Even half a cup lands at 4.5 grams, more than a medium banana. A full cup comes within a whisker of the 10 gram mark.
The FDA considers a food high in a nutrient when one serving provides 20% of the Daily Value or more. A cup of guava clears that bar by a wide margin, and 100 grams falls just short at 19%.
What makes guava so fibrous
Three features of the fruit work together to push its fiber number up.
You eat the peel
Guava skin is thin and edible, so when you eat the fruit whole, that outer layer counts toward your fiber. Research on guava processing shows how fiber dense that layer is: a 2021 study found flour made from guava peel contained 72 grams of fiber per 100 grams.
When the researchers stirred just 5% of a guava by-product flour of pulp and peel into guava juice, the juice’s fiber rose from about 1.0 to 4.9 grams per 100 grams. Their lab results showed a roughly two- to five-fold increase across the blends they tested.
Fiber outweighs much of the sugar
Per cup, guava has 8.9 grams of fiber against 14.7 grams of sugar. That’s about 0.6 grams of fiber for every gram of sugar, a far higher ratio than most everyday fruit.
For comparison, the FDA’s label values give a medium banana 3 grams of fiber with 19 grams of sugar, a ratio of about 0.16. A large apple sits near 0.2, and a medium pear near 0.38.
A modest calorie count
Guava delivers 7.9 grams of fiber per 100 calories. That’s roughly double an apple or an orange, so you get a lot of fiber before the calories add up.

How guava ranks against the highest fiber fruits
The Dietary Guidelines’ food source tables list fiber per standard portion. Here are the top fruits, with guava near the very top:
| Fruit (1 cup unless noted) | Fiber |
|---|---|
| Sapote or sapodilla | 9.5 g |
| Durian | 9.2 g |
| Guava | 8.9 g |
| Nance | 8.4 g |
| Raspberries | 8.0 g |
| Loganberries | 7.8 g |
| Blackberries | 7.6 g |
| Soursop | 7.4 g |
| Boysenberries | 7.0 g |
| Gooseberries | 6.5 g |
| Asian pear (1 medium) | 6.5 g |
Durian edges guava by 0.3 grams, but the same table lists it at 357 calories per cup, more than three times guava’s 112. Sapote, durian and nance can also be hard to find, which leaves guava and raspberries as the practical leaders for many shoppers.
Guava versus everyday fruit
Set beside the fruits most people eat every week, the gap gets wider. The FDA’s raw fruit label values give these servings:
- Medium pear: 6 grams for 100 calories
- Large apple: 5 grams for 130 calories
- Two kiwifruit: 4 grams for 90 calories
- Medium banana: 3 grams for 110 calories
- Medium orange: 3 grams for 80 calories
A cup of guava beats every one of them, and the pear, its closest rival here, still trails by about 3 grams.
Guava versus other tropical fruit
Within the tropical aisle, guava’s lead is even clearer. A cup of fresh papaya cubes gives about 2.5 grams of fiber for 62 calories in USDA data, and two slices of pineapple give 1 gram for 50 calories on the FDA’s label list.
Passion fruit is the one tropical fruit that competes per calorie, with 6.1 grams in a quarter cup for 57 calories. Pair the two, a cup of guava and a quarter cup of passion fruit pulp, and you reach 15 grams, more than half the Daily Value in one bowl.
Fresh guava versus nectar and paste
Guava often shows up in processed form, especially as nectar or the sweet paste used in pastries. Those versions keep very little of the fresh fruit’s fiber.
| Per 100 grams | Calories | Fiber | Total sugars | Vitamin C |
|---|---|---|---|---|
| Fresh guava | 68 | 5.4 g | 8.9 g | 228 mg |
| Guava nectar | 48 | 1.2 g | 10.2 g | 21.3 mg |
| Guava paste | 292 | 1.1 g | 71.6 g | 43.9 mg |
Nectar holds less than a quarter of the fresh fruit’s fiber and about a tenth of its vitamin C. Paste is mostly sugar: a 32 gram medium piece carries roughly 23 grams of sugar and only about 0.4 grams of fiber.
So the fiber story belongs to the whole fruit. If a recipe calls for paste, enjoy it as a sweet rather than counting it toward your fiber.
Guava nutrition beyond the fiber
The vitamin C number in guava is startling. One cup supplies 376 milligrams, about 418% of the 90 mg Daily Value.
- Potassium: 688 mg per cup, about 15% of the Daily Value.
- Folate: 81 micrograms, about 20% of the Daily Value.
- Copper: 0.38 mg, about 42% of the Daily Value.
- Protein: 4.2 grams.
- Lycopene: about 8,600 micrograms, a red carotenoid pigment.
That’s a lot of nutrition packed into 112 calories. The fiber is the headline, but the vitamin C may be the bigger surprise.
Guava inside a full day of fiber
One cup of guava does a lot of the heavy lifting, but a 28 gram day still needs a few more fiber sources. Here is one way to build it using the Dietary Guidelines numbers:
- Breakfast: oatmeal with 1/2 cup of sliced guava stirred in at the end: guava adds 4.5 grams.
- Lunch: a salad with 1/2 cup of chickpeas: 6.3 grams.
- Afternoon: the other 1/2 cup of guava as a snack: 4.5 grams.
- Dinner: 1/2 cup of black beans with cooked vegetables: 7.5 grams plus whatever the vegetables bring.
Without counting the oatmeal or vegetables, that’s 22.8 grams, about 81% of the Daily Value. Splitting the guava into two half cup servings also gives you a sweet, vitamin C rich bite at two points in the day.
Getting guava ready to eat
Ripe guava gives slightly when you press it and smells sweet and floral at the stem end. Rinse it, trim the ends and slice it into wedges or rounds, peel left on.
The center holds many small, hard seeds. Some people eat them along with the flesh, while others scoop the seedy core out and eat the firmer outer flesh; either way, keeping the peel holds onto the most fiber dense layer.
Sliced guava is good with a squeeze of lime and a pinch of chili or salt. It also works chopped into salsa, blended into smoothie bowls or tossed into a fruit salad with pineapple and mango.
Guava, gut health and adding fiber comfortably
A cup of guava is a big fiber jump if your current diet is light on fruit, vegetables and whole grains. Harvard’s Nutrition Source advises increasing fiber gradually and drinking plenty of fluids as you do.
A practical way to follow that advice is to start with half a cup, which gives about 4.5 grams. Move to a full cup once your body has adjusted over a week or two.

One snack swap, worked through
Picture your usual 3 p.m. snack: a medium banana, 3 grams of fiber and 110 calories. Swap it for a cup of sliced guava and you get 8.9 grams for 112 calories.
That single change adds almost 6 grams of fiber a day for 2 extra calories. Across a week it adds up to about 41 extra grams, close to a day and a half of the Daily Value.

Choosing the right guava for you
If you want the most fiber per bite, buy whole fresh guava and eat the peel. If fresh guava is hard to find, check the frozen aisle, and compare the fiber and added sugar lines on the label before you buy.
If the only guava on the shelf is nectar or paste, file it under treats and get your fiber from raspberries or a pear instead. And if you’re new to high fiber eating, start with half a cup and work up.
