Overview
Macadamia nuts (Macadamia integrifolia and Macadamia tetraphylla) are native to Australia and now widely cultivated in Hawaii, prized for their rich, buttery flavor and creamy texture. These premium nuts are exceptionally high in heart-healthy monounsaturated fats, particularly the rare omega-7 palmitoleic acid.

Key nutrition highlights
- Omega-7 palmitoleic acid: one of the richest dietary sources of this beneficial monounsaturated fat.
- Very high monounsaturated fats: 59g per 100g, supports heart health.
- Low omega-6 ratio: beneficial fatty acid balance compared to most nuts.
- Thiamin (B1): supports energy metabolism and nervous system function.
- Manganese: important for bone health and antioxidant defense.
- Copper: essential for iron metabolism and collagen formation.
Tip: Raw macadamias have a milder, creamier flavor than roasted. Both are nutritious choices.
Typical origins & sourcing
Macadamia nuts are primarily grown in Australia, Hawaii, South Africa, and Kenya. Prioritize:
- Health food stores: widely available in bulk bins and packages.
- Online retailers: many specialty suppliers offer raw and roasted options.
- Hawaiian sources: premium quality, often with unique flavor profiles.
- Australian sources: original native cultivation with heritage varieties.
