Macadamia Nuts Posted on May 20, 2023

If macadamia nuts are your favorite, you’ve come to the right place. Let’s explore the health benefits of this delicacy, nutritional profile, and more interesting facts about them, including how to roast them at home. Keep reading to learn more about macadamia nuts!

Are macadamia nuts tree nuts?

Not many nuts are true nuts. Does that sound confusing? The problem is that botanists use the term differently than most people. By definition, we tend to think of any type of oily seed with a large kernel hidden within a hard shell as a nut. But if this shell reveals a seed that is not fused to it, then it’s not a nut at all. That’s the case with walnuts, pecans, peanuts… And yes, also macadamia nuts, which are actually a type of seed.

Where are macadamia nuts grown?

Macadamia trees were first discovered in Australia in 1828.

Aboriginal peoples called it “Kindal Kindal”, “Bauple” or “Jindil”. The nuts were considered a real delicacy, often enjoyed on special ceremonial occasions.

Today, most of the world’s cultivated macadamias are grown in Hawaii, but curiously enough, most of them (if not all) appear to stem from a small group of trees, or even just a single tree, in Queensland.

Are they healthy?

Here are some nutritional facts about macadamias and some of their (many) health benefits:


The nuts are a great source of mono-unsaturated healthy fats like oleic acid and palmitoleic acids. Studies prove that these fats can help lower LDL (bad) cholesterol and increase HDL (good) cholesterol levels in the blood.

They may improve bone health. Macadamias  contain calcium, magnesium, and potassium, three minerals that are known to boost bone health.


Macadamias are rich in calcium, iron, magnesium, manganese and zinc. For reference, 100g contains 3.6 µg of selenium, a cardio-protective micro-mineral that also acts as an important antioxidant cofactor for glutathione peroxidase enzyme.

100 g of macadamia nuts provides 23% of the daily-recommended levels of dietary fiber.


The nuts are also full of B-complex vitamins that are vital for metabolic functions. These vitamins help a series of enzymes do their jobs, which includes releasing energy from carbohydrates and fat, breaking down amino acids and transporting oxygen and energy-containing nutrients around the body.

How to roast them

Roasting macadamia nuts is easy! Just remember to keep an eye on them at all times. Since they’re so fatty, the high oil content means they will burn quickly!

Preheat your oven to 225F and arrange the nuts on a shallow roasting tray in a single layer. Roast until the nuts develop a lightly golden, tan color, about 10 minutes. Gently shake the pan about halfway through the process to ensure even roasting and prevent burning spots. Remove from the oven and place them in a cool place.
