How many calories are in macadamia nuts?

1 oz (10-12 kernels) of macadamia nuts supplies 204 calories, which scales to 718 per 100 g. Each serving listed underneath was weighed by USDA rather than estimated.

Macadamia nuts and its protein content

1 oz (10-12 kernels) of macadamia nuts provides 2.2 g of protein. Set beside the 50 g reference intake, that is 4 percent. Only 4 percent of its calories come from protein, so treat macadamia nuts as something you eat for other reasons and count the protein as a bonus.

Its energy is 89 percent fat, 7 percent carbohydrate and 4 percent protein, meaning it behaves as mostly a fat in a meal.

What cooking does to macadamia nuts

Same macadamia nuts, same 28 g, different treatment:

Macadamia nuts in the kitchen

These spherical, pale Australian nuts are sold shelled, either raw or dry-roasted. Because of their exceptionally hard shells, cracking them at home is impractical. Choose plump, cream-coloured kernels that look dry rather than oily in the packet. Avoid any with a yellowish tint or a dusty surface, which indicates age and rancidity.

Their high oil content means these kernels scorch quickly. Toast them gently in a dry pan, shaking constantly, until they turn pale golden. The common mistake is using high heat, which burns the exterior while leaving the inside raw. Once toasted, transfer them to a cold plate immediately to stop the cooking.

These waxy nuts pair well with white chocolate and coconut in Western baking. In savoury cooking, crush them to coat white fish or toss them through Cantonese stir-fries. Their buttery texture also suits rich pestos, where they replace pine nuts, or they can be ground into a smooth, dairy-free butter.

Micronutrients in macadamia nuts

The figures worth noticing in 1 oz (10-12 kernels) of macadamia nuts are 28 percent of a day’s thiamin. The full list follows and tracks your selected portion.

Macadamia nuts packs 8.6 g of fibre into 100 g, covering 31 percent of what the label rules call a day’s worth.

How far macadamia nuts goes in a day

If you eat 2,000 calories a day, 1 oz (10-12 kernels) of macadamia nuts accounts for 10 percent of them, and for 4 percent of the 50 g protein benchmark. To replace 2,000 with your real number, use the TDEE calculator; to turn that into targets, the macro calculator.

How should macadamia nuts be stored?

Keep them in an airtight container in the fridge or freezer. Their high fat content makes them spoil rapidly at room temperature. Cold temperatures keep the oils stable, preserving their mild, buttery flavour for much longer.

Bitterness indicates that the delicate oils have oxidised and gone rancid. This happens when the kernels are exposed to light, warmth and air. Throw away any bitter nuts, as this off-flavour cannot be cooked out.
