The Brazil nut is the edible kernel from the nut of the Brazil nut tree. It is a native of the Amazon rainforest.
Brazil nuts are 18% protein, 13% carbohydrates, and 69% fat. The fat breakdown is roughly 25% saturated, 41% monounsaturated, and 34% polyunsaturated. They are somewhat earthy in flavour. The saturated fat content of Brazil nuts is among the highest of all nuts, surpassing even macadamia nuts. Because of the resulting rich taste, Brazil nuts can often substitute for macadamia nuts or even coconuts in recipes. Shelled Brazil nuts soon become rancid. The nuts are also pressed for oil. Brazil nuts are very large in size compared to some other nuts.
