Breadfruit

Breadfruit (Artocarpus altilis) is a large, starchy fruit native to the Pacific islands and now cultivated across tropical regions including the Caribbean, West Africa, and Southeast Asia. It is typically harvested when immature and green, then boiled, fried, roasted, or mashed as a carbohydrate staple in place of grains or potatoes. When ripe, it becomes sweeter and is sometimes eaten as a dessert. The flesh is mild, slightly nutty, and has a texture similar to potato or cassava when cooked.

Breadfruit contains approximately 27 grams of carbohydrate per 100 grams of cooked fruit, with roughly 2–5 grams of fiber depending on ripeness and preparation. It is low in fat and protein and provides moderate amounts of vitamin C (around 15% of the daily value per 100 grams), potassium, and smaller amounts of manganese and B vitamins. The carbohydrate composition shifts from complex starch when unripe to simpler sugars as the fruit ripens. Unripe breadfruit contains resistant starch, a type of starch that resists digestion in the small intestine and reaches the colon largely intact, where it functions similarly to dietary fiber and may support colonic bacterial fermentation.

Blood Sugar and Glycemic Response

Breadfruit has a moderate to high glycemic index depending on ripeness and preparation method. The glycemic load is moderate because portions are typically modest. Unripe breadfruit, which contains more resistant starch, produces a lower postprandial glucose response than ripe breadfruit. Individuals managing blood sugar or living with diabetes should account for breadfruit as a starchy carbohydrate and pair it with protein or fat to moderate glucose absorption.

Tolerance and Consumption Guidance

Breadfruit is not commonly associated with food allergies, though individuals with latex-fruit syndrome may experience cross-reactivity given breadfruit's membership in the Artocarpus genus; sensitized individuals should exercise caution. It is low in common allergens and contains negligible amounts of antinutrients of concern for most people. A typical serving is 100–150 grams of cooked fruit. No special cautions apply to most healthy adults; those with kidney disease should monitor potassium intake if consuming large quantities, as breadfruit is relatively high in potassium compared to many other starchy vegetables.
