These nuts are RAW, not cooked or roasted.

Nutritionally, Brazil nuts are a good source of some vitamins (thiamin and vitamin E) and minerals (calcium, magnesium, phosphorus, copper and manganese) and are perhaps the richest dietary source of selenium. The saturated fat content of Brazil nuts is among the highest of all nuts, surpassing macadamia nuts, which are primarily monounsaturated fat, and the nuts are pressed for their oil. Because of the resulting rich taste, Brazil nuts can often substitute for macadamia nuts or even coconut in recipes. Due to their high polyunsaturated fat content, primarily omega-6, shelled Brazil nuts soon become rancid so it is best to keep them in the refrigerator.
