Meet Hawaiian ‘Ulu, the Protein-Rich Tropical Superfruit

By Elisabeth Almekinder, Health Journalist, Registered Nurse, and Diabetes Educator for the Manos Unidas North Carolina Farmworker Health Program

“’ULU.” The word rolls off the tongue but may be unfamiliar to mainland folks. Also known as breadfruit, ‘ulu is a local produce found on the Hawaiian Islands and in the Caribbean, South Asia, and Polynesia that is nutritious, delicious, underutilized, and extremely versatile—it can be enjoyed and prepared as a fruit or a vegetable. When roasted, it resembles baked bread.  When ripe, you can eat the soft, pudding-like texture like a custard.

A sustainable fruit

An ancient example of modern-day sustainable agriculture, the life of an ‘ulu tree spans decades. As legend has it, the god Ku transformed himself into an ‘ulu tree to feed his human family and spread the fruit trees throughout the Hawaiian Islands.


The islands are rich with folklore related to the plant. One of the highest yielding food trees on earth, one tree can produce over 100 to 200 fruits in a year’s time with little effort, and they grow well in backyards as well as on farms among other varieties of trees. The trees are fast-growing and require very little labor, fertilizer, or pesticides compared to other crops. Scientists also believe that ‘ulu could be a way to combat hunger and malnourishment in subtropical climates like Haiti and Jamaica where the tree could easily flourish.

What are the health benefits of ‘ulu?

It’s considered a superfood not only because one fruit feeds an entire family and there’s enough fruit on the islands to feed the whole population, but due to its nutritional value. It’s sometimes called the tree potato for how versatile it is in cooked dishes and for how it tastes when it’s mature. But it higher in protein, fiber, vitamins, and minerals than white potatoes.

There are many nutrients packed into one fruit. ‘Ulu is loaded with:

  • Antioxidants
  • Carotenoids
  • Fiber
  • Iron
  • Magnesium
  • Niacin
  • Omega 3 fatty acids
  • Omega 6 fatty acids
  • Calcium
  • Copper
  • Phosphorus
  • Potassium
  • Thiamine
  • Protein
  • Vitamin A
  • Vitamin C

What does it taste like?

You can eat and enjoy ‘ulu at any stage. When it’s green and hard, it tastes like an artichoke. When it’s mature, it tastes and cooks like a potato or other root vegetable. When very ripe, it’s sweet and is enjoyed like fruit or dessert.

How do you eat it?

It can be eaten in the raw state or steamed and pounded into poi or added to desserts and drinks. It can be fried, baked, or made into a gluten-free flour. (1) In Hawaii, the traditional method of cooking is by roasting the fruit. It is also cooked in deep fire pits, called “imu.”

In its immature state before ripeness occurs, it’s cooked much like a green vegetable and tastes like artichokes. You can use it as a healthier substitute for potatoes in your homemade dishes. (2)

“My wife mashes it like potatoes and makes it into baked french fries and chips,” said Randy Malfalfa, musician and resident of Big Island. “It helps me to keep my Type 2 Diabetes in control because it raises my blood sugars less than potatoes.”

At the size of a small basketball, this green-colored fruit can be made into pancakes, stews, soups, salads, casseroles, bread, and dips. It can be formed into vegetarian burgers. It can be marinated or pickled or used in curries.

From making it into a dough and rolling it out for pizzas, pasta, and tamales to peeling and eating the raw fruit, ‘ulu is a versatile superfood. It’s used for other purposes, such as an insect repellant, in waterproof caulking, chewing gum, to make clothing, and as a nutritious option for animal feeds. (3)

I don’t live in Hawaii, so where can I get breadfruit?

If shopping local specialty grocery stores, you may not find breadfruit. It is available for shipment from the Hawaiian Islands through several distributors and Amazon.

Ho’oulu Ka ‘Ulu Project

On the Big Island of Hawaii, 16 different organizations have banded together for the sustainability “Ulu Project.” Together, they are promoting breadfruit in areas of research, culture, history, and environmental forums to address food insecurity on the island.

Efforts to globalize ‘ulu are underway, with gluten-free flours sold in the U.S. and Asian countries and to propagate ‘ulu throughout the Pacific Islands where it best grows. (4)
