All fruits contain fructose. It’s one of the primary natural sugars in every piece of fruit you eat, alongside glucose and sucrose. But the amount varies dramatically, from about 1 gram in a cup of cranberries to over 12 grams in a medium apple. Understanding which fruits are highest and lowest in fructose matters if you’re managing fructose malabsorption, watching your sugar intake, or simply curious about what’s in your food.
How Fructose Works in Fruit
Fruits contain three main sugars: fructose, glucose, and sucrose (which is itself a combination of fructose and glucose bound together). Fructose is the sweetest of the three, which is why fruits with higher fructose-to-glucose ratios often taste sweeter. Your body processes fructose differently from glucose. While glucose can be used by virtually every cell in your body, fructose is processed almost entirely by the liver.
The ratio of fructose to glucose in a fruit matters more than many people realize. When fructose and glucose are present in roughly equal amounts, glucose helps your intestines absorb fructose more efficiently. Fruits where fructose significantly exceeds glucose, like apples and pears, are more likely to cause digestive discomfort in people who are sensitive to fructose. In apples, fructose is by far the dominant sugar. Peaches show enormous variety depending on the specific cultivar, with fructose-to-glucose ratios ranging from 0.4 to 2.5.
Fruits Highest in Fructose
These fruits pack the most fructose per typical serving:
- Mangoes: About 16 grams of fructose in one whole fruit. Mangoes also contain substantial sucrose, making them one of the sweetest fruits overall.
- Apples: Around 12 to 13 grams per medium apple. Apples have a high fructose-to-glucose ratio, meaning fructose dominates their sugar profile.
- Pears: Roughly 11 to 12 grams per medium pear. Like apples, pears have significantly more fructose than glucose, which is why they’re one of the most common triggers for people with fructose sensitivity.
- Grapes: About 12 grams per cup. Despite tasting very sweet, grapes actually have a more balanced fructose-to-glucose ratio than apples.
- Watermelon: Around 11 grams per two-cup serving. A single wedge can contain even more because people tend to eat watermelon in large portions.
- Cherries: About 8 grams per cup. Cherries also contain sorbitol, a sugar alcohol that can compound digestive issues for fructose-sensitive individuals.
- Bananas: Around 5 to 7 grams per medium banana, depending on ripeness. As bananas ripen, their starch converts to sugar, increasing fructose content.
Dried fruits deserve special mention. Because the water has been removed, fructose becomes concentrated. A quarter cup of raisins contains about 12 grams of fructose, roughly the same as an entire cup of fresh grapes. Dried figs, dates, and dried mangoes are similarly concentrated.
Fruits Lower in Fructose
If you’re looking to limit fructose while still eating fruit, several options keep you well under 5 grams per serving:
- Strawberries: About 3.5 grams per cup. They also have a nearly equal fructose-to-glucose ratio, which aids absorption.
- Blueberries: Around 3.5 grams per half cup.
- Raspberries: Roughly 3 grams per cup, with the added benefit of high fiber content.
- Kiwi: About 3 grams per fruit.
- Oranges: Around 3 to 4 grams per medium orange. Citrus fruits in general tend to be moderate in fructose.
- Cantaloupe: About 3 grams per cup of cubed melon.
- Cranberries: Roughly 1 gram per cup (fresh, unsweetened). They’re among the lowest-fructose fruits available, though few people eat them without added sugar.
Berries as a category tend to be your best bet for low-fructose fruit. They’re generally lower in total sugar, higher in fiber, and have balanced fructose-to-glucose ratios.
Why Whole Fruit Handles Differently Than Juice
A glass of apple juice contains roughly the same fructose as two or three whole apples, but your body responds to them very differently. Whole fruit contains fiber, which slows the rate at which sugar enters your system. The physical structure of fruit cells also takes time to break down during digestion, spreading fructose absorption over a longer period. When you drink juice, that fructose hits your liver in a concentrated rush.
This is why most dietary guidance draws a sharp line between whole fruit and fruit juice. The fructose in a whole apple, delivered alongside 4 grams of fiber and consumed over several minutes of chewing, presents a fundamentally different metabolic challenge than the same fructose dissolved in a glass of juice you can drink in 30 seconds.
Fructose in Fruit vs. Other Foods
Compared to fruit, most vegetables contain very little fructose. A medium tomato has about 1.7 grams of total fructose. A cup of sliced cucumber has just 1.1 grams. A cup of sliced green peppers contains 2.2 grams. Even concentrated forms like canned tomato paste only reach about 3.8 grams per quarter cup. Vegetables are rarely a concern for people watching their fructose intake.
The bigger source of fructose in most diets isn’t fruit at all. It’s added sugars, particularly high-fructose corn syrup, found in soft drinks, flavored yogurts, cereals, condiments, and packaged snacks. A single 12-ounce can of soda typically contains 20 to 25 grams of fructose. Table sugar (sucrose) is 50% fructose by weight, so anything sweetened with it contributes meaningful amounts as well. For most people, reducing added sugars will lower fructose intake far more than cutting back on fruit.
Who Needs to Track Fructose Intake
For the average person, the fructose in whole fruit is not a health concern. The fiber, vitamins, and other beneficial compounds in fruit more than offset the sugar content, and population studies consistently link higher fruit consumption with better health outcomes.
Fructose tracking becomes important in two situations. The first is fructose malabsorption, a condition where your small intestine can’t efficiently absorb fructose. This affects an estimated 30 to 40% of people to some degree, though most never notice symptoms. For those who do, eating high-fructose fruits (especially those with excess fructose over glucose, like apples and pears) can cause bloating, gas, abdominal pain, and diarrhea. People following a low-FODMAP diet for irritable bowel syndrome also limit high-fructose fruits for the same reason.
The second situation is hereditary fructose intolerance, a rare genetic condition diagnosed in infancy that requires strict fructose avoidance. This is managed under medical supervision and is entirely different from the more common malabsorption issue.
If fructose bothers you, start with the lower-fructose fruits listed above, pay attention to portion size, and favor fruits where fructose and glucose are present in roughly equal amounts. Berries, citrus, and kiwi are typically the best tolerated.
