Most fruits contain zero fat. According to FDA nutritional data, common fruits like apples, bananas, oranges, grapes, strawberries, and watermelon all register 0 grams of fat per serving. But a small group of fruits break this rule dramatically, with some packing more fat per serving than a tablespoon of butter.
Avocado: The Fattiest Fruit
A whole medium avocado contains about 22 grams of fat and 240 calories. That’s more fat than you’d find in many cuts of meat. About 15 of those grams come from monounsaturated fat, the same heart-healthy type found in olive oil. Even a small one-fifth of a medium avocado (roughly a thin slice) delivers 4.5 grams of fat.
The fat in avocados serves a practical purpose beyond calories. Vitamins A, D, E, and K only dissolve in fat, which means your body needs dietary fat to absorb them. Eating avocado alongside vegetables like spinach, carrots, or tomatoes helps your body pull more of those nutrients into your bloodstream. This is why a drizzle of olive oil or a few slices of avocado on a salad isn’t just for flavor.
Coconut: High in Saturated Fat
A small piece of raw coconut meat (roughly a 2-by-2-inch chunk) contains about 15 grams of fat. What sets coconut apart from avocado is the type: nearly 13.4 of those grams are saturated fat. That makes coconut one of the most saturated fat-dense whole foods in any category, not just among fruits.
Coconut’s fat profile is closer to butter than to other plant foods. The remaining fat is split between tiny amounts of monounsaturated and polyunsaturated fats, both under 1 gram per piece. Whether you’re eating fresh coconut, dried flakes, or coconut cream, the saturated fat content stays proportionally high.
Olives: Small but Fatty
Olives are botanically a fruit, and even a small serving carries measurable fat. Three canned ripe olives (about 12 grams total) contain 1.3 grams of fat. That sounds modest, but most people eat far more than three at a time. A handful of 10 olives approaches 4 to 5 grams.
The fat in olives is predominantly monounsaturated, specifically oleic acid, the same fatty acid that gives olive oil its nutritional reputation. In a three-olive serving, nearly 0.9 grams of the 1.3 total grams come from oleic acid. Green and black olives have similar fat profiles, though brine-cured varieties may differ slightly in water content.
Durian: A Tropical Outlier
Durian, the notoriously pungent Southeast Asian fruit, contains 3 to 5 grams of fat per 100-gram serving. That’s modest compared to avocado or coconut, but it’s still far more than virtually any other tropical fruit. A 100-gram portion also delivers 130 to 180 calories, with most of the energy coming from carbohydrates rather than fat.
Like avocado, durian’s fat is primarily monounsaturated. It’s calorie-dense for a fruit, though, so the fat adds up quickly if you eat a full segment or two. Durian is commonly eaten fresh across Thailand, Malaysia, and Indonesia, and its creamy, custard-like texture comes partly from that fat content.
Ackee: Jamaica’s Fatty Fruit
Ackee is less well known outside the Caribbean, but it’s one of the fattiest fruits in existence. The edible flesh is between 51% and 58% fat by dry weight, and a 100-gram serving of canned, drained ackee contains 15.2 grams of fat. That puts it in the same range as avocado.
The fat profile is unusual for a fruit. The dominant fatty acid is linoleic acid (a polyunsaturated omega-6 fat), which accounts for over 55% of the total fat. The rest is a mix of palmitic and stearic acids. Ackee is a staple in Jamaican cuisine, typically cooked with saltfish, and its rich, buttery texture reflects its high lipid content.
Palm Fruit
The fruit of the oil palm is rarely eaten whole, but it deserves mention because it’s one of the fattiest fruits on earth. The fleshy outer layer of a mature palm fruit is about 50% oil by weight. Two different oils come from it: palm oil from the flesh and palm kernel oil from the seed inside, each with a distinct fat profile.
Palm oil from the flesh is roughly half saturated fat and half unsaturated fat, with significant amounts of oleic and linoleic acids. Palm kernel oil is far more saturated, above 80%, and rich in shorter-chain fatty acids used in confectionery products. You won’t find whole palm fruit at a grocery store, but palm oil derived from it is one of the most widely consumed fats in the world, found in everything from peanut butter to frozen pizza.
How Fatty Fruits Compare to the Rest
The gap between fatty fruits and ordinary fruits is stark. FDA data lists the fat content of 20 common fruits, and the majority register exactly 0 grams. A large apple: 0 grams. A medium banana: 0 grams. A cup of grapes: 0 grams. Two cups of diced watermelon: 0 grams. The only common fruits that show even a trace are kiwifruit (1 gram for two medium), nectarines (0.5 grams), and peaches (0.5 grams).
Compare that to avocado, where a single fifth of the fruit already has 4.5 grams, or coconut, where a small piece delivers 15 grams. The reason most fruits are fat-free is that they store energy as sugars rather than lipids. Avocado, coconut, olives, and ackee are evolutionary outliers, fruits that developed oily flesh likely to attract specific animals for seed dispersal.
If you’re looking to add healthy fats through whole fruits, avocado and olives are the most accessible and best studied for cardiovascular benefits. Coconut provides fat too, but its heavily saturated profile makes it a different nutritional choice. For most people, the practical takeaway is simple: the overwhelming majority of fruits are essentially fat-free, and the handful that aren’t tend to be the ones with a creamy or oily texture rather than a sweet, juicy one.
