Everything you need to know about Brazil nuts

Whether you have enjoyed Brazil nuts for years or are considering trying them for the first time, Brazil nuts can be a flavor packed and healthy addition to your diet. Here is everything you need to know about Brazil nuts. 

Let’s take a little look into the background of this protein packed and nutritious nut from South America. Brazil nuts are very unique in the way that they are grown and harvested. Here’s some information on the Brazil nut, how they can help your health and well being, as well as how you can easily add them to your daily diet. 

What are Brazil nuts?


Actually a seed, rather than a nut, Brazil nuts are known for their smooth texture, and creamy nutty taste. Grown in South America in non-flooded rainforest regions, Brazil nuts are an important part of daily diet in the Amazon region. One of the most valuable products from the Amazon, Brazil nuts have also been enjoyed and exported for hundreds of years and are particularly popular in Europe and North America. The Brazil nut industry plays an important role in protecting the rainforest, since the fruit are harvested from the forest floor and not by disturbing the trees. So it’s not just your body that will thank you for munching on these nutritious nuts, the Amazon rainforest will too!

If you’ve never googled a photograph of a Brazil nut tree before, I suggest you do so now, because they are awesome! Brazil nut trees, also known as Bertholletia excelsa are one of the tallest and longest living trees in the Amazon rainforest. They grow up to 50 meters in height and often live to be 800 to 1000 years old. When properly pollinated, the fruit of the Brazil nut takes about 14 months to mature and is similar in appearance to a wooden coconut, weighing up to 5 pounds. Inside the hard shell of the Brazil nut fruit are between 8 and 24 triangular seeds that are packed in together similar to orange segments. The seeds that are found inside are what is valued for dietary and nutritional purposes.

Check this out; in addition to being used as a food source, the oil extracted from Brazil nuts is used in the production of many health and beauty products as well as clock oil. (Who knew?) Brazil nut tree wood is also highly valued and used for a variety of purposes including flooring, furniture and instruments. Whether it’s used to make your kitchen table or your favourite vegan cheese, there’s no denying how versatile the Brazil nut really is!

Where do Brazil nuts come from?


Despite the name, Bolivia is actually the world’s larger producer of Brazil nuts. Grown in Bolivia, Peru, Colombia, Venezuela, Ecuador and Brazil, these naturally harvested nuts come from trees native to the Amazon rainforest. Brazil nut trees grow best in the lowland rainforest and are often found in groups of 50 or more trees which are also known as stands.

How are Brazil nuts grown?

While a small amount of Brazil nuts are grown on plantations, most Brazil nuts are harvested directly from the rainforest because of the unique jungle ecosystem of pollination and regrowth.

To bear fruit, Brazil nut trees require that their flowers be pollinated by a specific species of bee. The orchid bee lives in the forest where the trees are found, and also requires the fragrance from a certain Amazon orchid in order to mate. If the orchid is not available, neither are the bees. With no bees to pollinate the flowers, Brazil nut trees fail to produce fruit, which is why they are usually only successful in forest areas instead of developed plantations.

Believe it or not, Brazil nuts trees rely on the help of a rodent to help with planting of new trees! The South American agouti is a small (super cute) animal that is able to break apart the hard and woody Brazil nut shells. After they eat their fill, the agouti buries the remaining seeds, allowing the Brazil nut trees to reproduce. Because the agouti often bury the seeds in shady areas due to the heavy canopy of the rainforest, many seeds will not start to germinate for many years, staying dormant until light is made available by a fallen tree. Once the Brazil nut tree starts to grow, it can take 15 to 30 years to start producing fruit.

How are Brazil nuts harvested?

Because the majority of Brazil nuts are found in the forest, the industry relies on migrant workers to collect the fruit. Known as castaneros, these brave farmers collect the Brazil nut fruit and help transport it to processing facilities. Below you’ll find out why these castaneros are so brave.

Brazil nuts start to fall between December and March. During this time, the castaneros move to the forest where they build camps and start their search for Brazil nuts. Using machetes, the castaneros open the fruit and place the nuts in bags until they can be taken out of the forest. They are then transported, usually via river, to the processing plants where they are peeled, dried, packaged and exported.

Here’s what shocked us- The tall height of Brazil nut trees and the large size of the Brazil nut fruit can make collection a dangerous job. When the nuts fall from the trees, the five pound shells fall at nearly 50 miles per hour and have been known to damage vehicles or even cause death when falling on individuals. Brazil nut harvesters keep this danger in mind while working, and often wear wide wooden hats for protection and do not collect fruit on windy days. The pods of fruit fall to the forest floor where they are collected. An established Brazil nut tree can produce as many as 300 fruits, which can harvest up to 6000 nuts per tree. Crazy right?

Brazil nut collection and the related business around it,is an important source of income for many forest communities. The Brazil nut business also encourages communities to conserve the existing forest. As long as Brazil nuts are in demand, there is an incentive to keep the forest preserved. It’s a win-win!
