Technically speaking, Brazil Nuts are a type of seed, since they are shelled in a thick cone. They are called "Brazil Nuts" because of their nut-like taste and flavor. They are slightly worse than Macadamia nuts in their fat profile (100 grams of brazil nuts has 15g SFAs, 25g MUFAs, and 19g PUFAs), but you won't be eating Brazil nuts solely for their fat profile. Why you need Brazil nuts is because of their epic selenium levels - 100 grams of Brazil nuts contain 1917 mcg of selenium. That is a whopping 2739% of your total daily requirement.
