What Are Brazil Nuts?

Brazil nuts come from the Bertholletia excelsa tree, an impressive species native to the Amazon rainforest that can reach heights of up to 160 feet and live for 500-800 years. Unlike many commercial nuts that grow on farms, Brazil nuts are primarily harvested from wild trees in the pristine forests of Bolivia, Brazil, Peru, Colombia, and Venezuela.

What makes these nuts truly special is their unique growing process. Brazil nuts develop inside coconut-sized seed pods called “pixidium,” with each pod containing 10-24 nuts arranged like segments of an orange. These heavy pods (weighing up to 5 pounds) fall to the forest floor when mature, where they’re collected by local harvesters.

Brazil nuts have been an important food source for indigenous Amazonian people for thousands of years. Nutritionally speaking, they stand out among all nuts and seeds for their extraordinarily high selenium content – just one nut can provide more than the daily recommended intake of this essential mineral.
