A breadfruit tree can produce 160–500 kg (350–1100 lb) of fruit per year with very little effort on the part of the grower.
Breadfruit produces abundant, nutritious fruit (i.e., high in carbohydrates and a good source of fiber, vitamins, and minerals) that is typically cooked and consumed as a starchy staple when firm and mature. Ripe fruit can be eaten raw or cooked, processed into chips and other snacks, dried into flour or starch, and minimally processed or frozen. Breadfruit flour can be partially substituted for wheat flour in many bread, pastry, and snack products. Seeds, cooked in the fruit and eaten throughout the Pacific islands—but rarely in Polynesia—are high in protein, relatively low in fat and a good source of vitamins and minerals. Breadnut seeds tend to be larger and sweeter than breadfruit seeds and can be roasted or boiled. In Ghana, breadfruit and breadnut seeds have been made into nutritious baby food. In the Philippines, immature fruit is sliced, cooked, and eaten as a vegetable.
