6 Proven Health Benefits of Macadamia Nuts, According to Nutrition Experts

When it comes to health, you really can’t go wrong with any variety of nut. Virtually all nuts are healthy—whether that be almonds, cashews, walnuts, pecans, pistachios, or otherwise. However, one of the most overlooked nuts is the macadamia nut.

While indigenous to Australia, macadamia nuts are commonly associated with Hawaii, as it’s one of the few places that can grow this unique tree nut. And aside from its rich history, macadamias are known for their delicate nutty flavor, crunchy texture, and culinary adaptability—perfect for both sweet and savory recipes.

But macadamia nuts have plenty to offer in the way of health benefits, too, thanks to their robust nutrition profile. Read on to discover all the impressive ways macadamia nuts can positively impact your overall health!

Are Macadamia Nuts Healthy?

To get a better understanding of just how nutritious macadamia nuts are, let’s take a look at its nutritional breakdown, according to the United States Department of Agriculture (USDA) database:

Raw Macadamia Nuts (1 ounce, 10-12 nuts)

Macronutrients
Calories: 204 calories
Protein: 2 grams (g)
Fiber: 3 g
Fat: 22 g
Saturated Fat: 3 g
Polyunsaturated Fat: 0.4 g
Monounsaturated Fat: 17 g

Micronutrients
Thiamin: 0.34 milligrams (mg), 28 percent of Daily Value (DV)*
Manganese: 1.2 mg, 52% DV
Copper: 0.2 mg, 22% DV
Magnesium: 37 mg, 9% DV
Iron: 1 mg, 6% DV

Based on this breakdown, we can see that macadamia nuts are a notable source of fiber, thiamin, manganese, and copper. The nuts also have modest amounts of protein, magnesium, and iron. 

However, the unsaturated fat content of the macadamia nut is what really sets it apart from other foods. In fact, macadamias have the highest percentage of monounsaturated fat per ounce of any popular nut.

Macadamia Nut Health Benefits

With this impressive nutrition profile, macadamia nuts can be linked to several health benefits. Here are six of the most noteworthy:

Gut Health

The fiber content of macadamia nuts bodes well for gut and digestive health. Fiber—when consumed with enough water—naturally promotes digestive regularity while soluble fiber acts as a prebiotic, or food for our health gut bacteria. Every fiber-containing food (macadamia nuts included) contains a mix of both soluble and insoluble fiber. The soluble fiber in this nut boosts the health of the gut microbiome by feeding the microbes it contains, helping the entire system thrive. The health of our microbiome is directly correlated to better digestion by aiding in nutrient digestion, helping us feel more comfortable throughout the process.

Metabolic Health

Speaking of fiber, this complex carbohydrate, when combined with the protein found in macadamia nuts, is also ideal for those with metabolic health concerns like type 2 diabetes. “This duo of nutrients helps support blood sugar balance and satiety,” says Roxana Ehsani, MS, RD, CSSD, sports dietitian. This is because fiber and protein slow digestion, resulting in less extreme blood sugar spikes and dips, more stable energy levels, and reduced cravings later in the day. “Plus, macadamia nuts are naturally low in carbohydrates,” Ehsani adds, further illustrating their blood sugar-regulating power.

Heart Health

If you’re worried about heart health—or just trying to stay ahead of it—the monounsaturated fat content of macadamia nuts is worth paying attention to. “Macadamia nuts are a rich source of heart-healthy monounsaturated fats which can help lower inflammation and support healthy cholesterol levels,” shares Ehsani, highlighting two major elements of cardiovascular disease development. Studies have even linked this fat to reduced hypertension (or high blood pressure)—another key risk factor for heart disease.

Immune Health

The inflammation reduction associated with the monounsaturated fats in macadamias also encourages better overall immune health, given that inflammation is a significant driver of both acute and chronic illness. In fact, monounsaturated fats have even been linked to reduced cancer risk. Additionally, the gut microbiome support of these nuts, thanks to their fiber content, further boosts immunity due to the close ties between the microbiome and immune response. 

Brain Health

When brain health is top priority, macadamia nuts are also a smart grab, as their fat content has been shown to champion brain health. One 2021 study found monounsaturated fat to be linked to brain health and better cognition, as these fats support neurotransmitter production and nerve cell health. The gut microbiome just so happens to be linked to better brain health as well.

Nutrient Absorption

And as if we haven’t raved about the fat content of macadamias enough, this nutritional facet also aids in nutrient absorption. “The fats found in macadamia nuts aid in absorption of fat-soluble vitamins,” explains Ehsani. The fat-soluble vitamins include vitamins A, D, E, and K, and (as their name implies) they require a fat source to be absorbed in the body. Macadamia nuts, macadamia nut butter, or macadamia oil can all support this process.

Ways to Enjoy Macadamia Nuts 

With these alluring health benefits, you may be wondering how to best enjoy macadamia nuts at home. Well, thanks to the neutral flavor of these nuts, the possibilities are nearly endless. “Macadamia nuts are slightly sweet, and buttery tasting. They taste great in savory or sweet meals or snacks,” Ehsani agrees.

If not enjoyed raw or toasted by the handful, macadamias can be seamlessly added to a variety of recipes. “Sprinkle chopped or whole macadamia nuts on a salad, grain bowl, oats, or slice of avocado toast for crunch,” Ehsani offers.

They can also be added to smoothies, breading for proteins, baked goods, or homemade granola. “Plus, you can make your own macadamia nut butter by processing [macadamia nuts] in a food processor until smooth and creamy. Spread on a slice of bread, or enjoy with fruit,” explains Ehsani. 

Though harder to find, macadamia nut oil is another delicious macadamia nut-based product that can be used in salad dressings, sauces, or simply for cooking and baking. Ultimately, macadamia nuts can be enjoyed just like any other nut (or nut butter or nut-based oil) you can think of. “However, keep in mind that nuts are high in total calories, so keep portion sizes in check—about a handful, or 10 to 12 macadamia nuts,” Ehsani reminds us.
