Macadamia integrifolia

Also known as Queensland nut, Bush nut

Potential health benefits

Best supported: Limited

Ordered by how well the human research supports them — strongest first. A rating describes the state of the evidence, not how impressive the food is. How we rate evidence.

Blood lipid profile

Heart Health
Limited evidence

Evidence is limited. A small number of controlled feeding trials report lower total and LDL cholesterol when macadamias replace saturated fat in the diet, consistent with the general effect of that substitution rather than anything specific to this nut.

Limited evidence. Early human work, or mostly lab and animal research.

Satiety and appetite

Weight Management
Limited evidence

Evidence is limited to a few short trials suggesting nuts in general increase fullness; macadamia-specific appetite research is minimal.

Nutrient values are per 100 g of the USDA reference entry named on this page and vary with variety, growing conditions, storage and preparation.

Source record: Nuts, macadamia nuts, raw (USDA FoodData Central, FDC ID 170178).

% DV uses the FDA Daily Values for adults and children aged 4 and over. A dash means no Daily Value has been established for that nutrient.

Bioactive compounds

Compounds present in meaningful amounts. Presence is banded rather than quantified, because whole-food levels vary enormously with variety, growing conditions, storage and preparation.

How preparation changes things

Only effects with real support are listed. If a preparation method is missing, it is because nothing dependable is documented — not because it makes no difference.

Nothing dependable is recorded about how preparation changes this food’s nutritional properties. Rather than guess, this section stays empty.

Things to know

Allergies, interactions and intake concerns. Every food gets this section — a reference where everything is uniformly good is not a reference.

  • Allergy

    Tree nut allergy

    Macadamia is a regulated tree nut allergen. Reported reactions are less common than to cashew or walnut but can be severe.

  • Worth knowing

    Very high energy density

    Macadamias carry more fat and more calories per gram than any other common nut, so the gap between a handful and a portion is wider than usual.

  • Worth knowing

    Toxic to dogs

    Macadamia nuts cause weakness, tremors and hyperthermia in dogs at small doses through a mechanism that is still unexplained. This is a real veterinary emergency and is worth knowing in a household with pets.
