Brazil Nuts Facts

Brazil nuts scientifically known as Bertholletia excelsa belongs within the family of Lecythidaceae, in the genus Bertholletia. The genus is named after the French chemist Claude Louis Berthollet. Its lifespan is about 500 to 700 years. Brazil nut tree bears a large capsule 10–15 cm (3.9–5.9 in) in diameter, resembling a coconut endocarp in size and weighing up to 2 kg (4.4 lb.). Internally, each fruit pod features 10-25 seeds (kernels), arranged in segments. Each kernel in turn is covered within its own thick dark-brown thin shell. Brazil nuts are eaten in whole form or their essential oil can be extracted and used for more direct remedies. It is important to consume shelled Brazil nuts fast, as the high content of fat makes these nut varieties go badly quite quickly.
