BRAZIL NUTS: Origin
The Brazil nut (Bertholletia excelsa) tree is enormous; frequently reach of 40 to 50 meters height or more, and it can reach ages of 500-800 years old. This tree is native in many northern parts of the South American continent, like Guiana, Bolivia, Venezuela, Brazil, Peru, Colombia and Ecuador. Madre de Dios is the only area in Peru where this kind of tree grows.
Between December and March , the coconuts fall from the tres , and the collector of the nuts ( known as Castañeros ) move to the middle of the amazonian forest in order to recollect the Brazil Nuts. The fruit is a large, round woody capsule or pod, about the size of a large grapefruit and weighing up to 2.2 kg. The fruit pods grow at the ends of thick branches, then ripen and fall from the tree from January to June, usually with a loud crashing sound as they fall 50 meters through the canopy like cannon balls. Inside each fruit pod, wedged in like orange segments, are 12 to 25 Brazil nuts, each within its own individual shell. Mature Brazil nut trees can produce approximately 300 or more of these fruit pods annually.
The Brazil nut is, in fact, a seed rather than a nut, but popular usage continues to prevail. Nutritionally, Brazil nuts are an excellent source of selenium and a good source of magnesium and thiamine. They are 14% protein, 11% carbohydrates, and 67% fat3 . The fat breakdown is roughly 25% saturated, 41% monounsaturated, and 34% polyunsaturated. The absolute saturated fat content of Brazil nuts is among the highest of all nuts, surpassing even macadamia nuts. The proteins found in Brazil nuts are very high in sulfur-containing amino acids like cysteine (8%) and methionine (18%) and are also extremely rich in glutamine, glutamic acid, and arginine. The presence of these amino acids (chiefly methionine) enhances the absorption of selenium and other minerals in the nut.

Traditional use of Brazil nuts
The Brazil nut is a three-sided nut with white meat or flesh that consists of 70% fat and 17% protein. For centuries the indigenous tribes of the rainforest have relied on Brazil nuts as an important and significant staple in their diet - so important, that the nuts have even been used as a trade commodity, much like money. Indigenous tribes eat the nuts raw or grate them and mix them into gruels. In the Brazilian Amazon, the nuts are grated with the thorny stilt roots of Socratea palms into a white mush known as leite de castanha and then stirred into manioc flour. This food is a valuable source of calories, fat, and protein for much of the Amazon's rural and tribal peoples. With such a high oil content, fresh Brazil nuts will even burn like miniature candles when lit. The oil is extracted from the nuts and used by indigenous and rural people for cooking oil, lamps, soap, and livestock feed. The empty seed pods, often called "monkey's pots," are used to carry around small smoky fires to discourage attacks of black flies, as cups to collect rubber latex from tapped trees, and as drinking cups. The husks of these seed pods have also been used in Brazilian folk medicine to brew into tea to treat stomachaches, and the tree bark is brewed into tea to treat liver ailments.
