What is Ulu (Breadfruit)?
Ulu, or breadfruit, is a staple food in many tropical regions, particularly across the Pacific Islands. It comes from the Artocarpus altilis tree and has been a central part of Polynesian diets for centuries. Depending on its maturity, ulu can be prepared and eaten in various ways, behaving like a starchy potato when young and savory, or becoming soft and sweet as it ripens, similar to a banana. Its recent rise in popularity in Western health food circles is due to its impressive nutritional profile and versatility.
The Nutritional Profile of Ulu
Ulu is much more than just a source of complex carbohydrates. A 100-gram serving of raw breadfruit contains around 103 calories and negligible fat. However, its true value lies in its high concentration of other beneficial nutrients:
- Carbohydrates: The main component of ulu, these complex carbs provide sustained energy without the sharp spikes associated with simple sugars.
- Dietary Fiber: Ulu is exceptionally high in fiber. A single serving can provide a significant portion of the recommended daily intake. The high amylose content, a type of insoluble fiber, is particularly beneficial for gut health.
- Complete Protein: Uniquely for a fruit, ulu contains a high-quality, complete protein with all the essential amino acids necessary for human health. The Ma'afala variety, for instance, has a higher percentage of essential amino acids than soybeans.
- Rich in Minerals: It is an excellent source of minerals vital for overall health, including potassium, magnesium, and copper.
- Vitamins: Ulu is packed with vitamins, including a significant amount of vitamin C, which is a powerful antioxidant, and B vitamins like thiamin (B1) and niacin (B3).
- Antioxidants: Beyond vitamin C, ulu contains other antioxidants like carotenoids, specifically lutein and beta-carotene, which are beneficial for vision and reducing inflammation.
