This September 4 food holiday celebrates a genus of trees native to Australia that produces a deliciously edible nut. Often used in baked goods and desserts, this versatile nut has a creamy, buttery taste.

High in healthy fats, macadamias are considered a good source of antioxidants that may boost heart health and lower the risk of heart disease.

Primarily observed in Australia and Hawaii, where macadamia nuts are a significant agricultural product, this food holiday celebrates its buttery taste, velvety texture, and nutritional benefits.
