Macadamia nuts are kernels produced by the macadamia nut tree, originally from Australia but now found in many parts of the world, including Hawaii. The nuts have a hard outer shell that is removed before the nuts are processed. Often the nuts are roasted or fried in oil, and nutrition values will vary depending on how the merchandiser processes the nuts. Macadamia nuts are sold as a snack food, widely used in baking, and are used to flavor products like ice cream.

The nutrition data provided by the USDA FoodData Central is for dry-roasted unsalted macadamia nuts. If the nuts are processed or cooked with oil or if other ingredients are added, the nutrition data will change.

Health Benefits 

Macadamia nuts are high in fat, but they also provide a boost of monounsaturated fat, considered a "good" fat. Monounsaturated fat (or MUFAs) come from plant sources and may be helpful in lowering your LDL or "bad" cholesterol. For this reason, the Academy of Nutrition and Dietetics recommends that you choose foods with monounsaturated fats instead of saturated fat.

Macadamia nuts also provide fiber. Eating foods with fiber can help you to feel fuller and more satisfied. Weight loss experts generally recommend that dieters consume foods with fiber to help them eat less and create the calorie deficit needed for weight loss.

Macadamia nuts are also a good source of thiamin and a very good source of manganese.

Common Questions About Incorporating Nuts in a Healthy Diet

Here are answers to a few common questions about eating nuts as part of a healthy diet.

What's the Best Way to Avoid Overeating Nuts?

Even though nuts provide health benefits, they are one of the most common foods to overeat. A single serving of macadamia nuts is just 10-12 kernels. But we usually don't count nuts before we eat them. To avoid overdoing it, use your hand to control portions. A small handful of nuts is a single serving.

Are Flavored Nuts or Nut Mixes Just as Healthy as Regular Nuts? 

Macadamia nuts are found in some, but not all nut mixes. When you buy nut blends or nut mixes, the nuts may be roasted in oil or seasoned with high sodium products. The result is that you may consume far more fat or sodium than you expect.

Can Nuts Be Part of a Weight Loss Diet?​

Nuts can make a smart snack if you are trying to lose weight. The protein and fiber in nuts may help you feel full and satisfied so you don't eat again soon after your meal.

How to Properly Store Macadamia Nuts

The best way to store nuts is to keep them in an airtight container at room temperature. They should stay fresh for about three months.

If you keep them in the refrigerator they should stay fresh for up to six months and if you freeze them you can use them for about one year.
