Brazil nut, also known as Brazil nut, Amazon nut or mountain chestnut, is one of the most appreciated nuts for its exceptional nutritional profile and its ability to provide important health benefits. Native to the Amazon rainforest and abundant in various South American countries, its consumption invites you to discover a natural, energetic food that is highly rich in selenium, magnesium, essential fats and antioxidant compounds.
What is Brazil nut?

The Brazil nut comes from the tree Bertholletia excelsa, a true wonder of nature, capable of reaching 50 or even 60 meters in height and living for centuries. This tree grows wild in the tropical rainforests of Brazil, Bolivia, Peru, Ecuador, Colombia, and Venezuela, with Bolivia being the world's largest exporter. Its fruit is a woody capsule resembling a coconut, but inside it contains between 10 and 24 seeds with the elongated shape so characteristic of the Brazil nut.
For centuries, Amazonian populations have consumed this fruit and incorporated it into their regular diet, taking advantage of both its nutritional and energy value. Sustainable harvesting of Brazil nuts is also a way to protect the Amazon rainforest from deforestation and to economically support local communities.

Recommended quantity and precautions for consumption
Because of his extremely high concentration of selenium, it is essential to consume Brazil nuts in moderation to avoid the toxic effects of excess selenium (selenosis). The ideal amount ranges from 1 to 4 Brazil nuts a day, which guarantees benefits without risk. For specific conditions such as selenium deficiency, some specialists suggest up to 4 units.
Excessive consumption (more than 10-12 nuts daily on a continuous basis) can induce symptoms of selenosis: hair loss, brittle nails, digestive discomfort, fatigue, altered taste, and kidney or liver problems.
Brazil nuts should be stored in a cool, dry place, protected from light. Being an oleaginous fruit, they tend to go rancid quickly if not properly stored. Furthermore, their shells can develop toxic mold, so they should never be eaten if they have a rancid smell or taste.
Contraindications and possible side effects

- Risk of lecithin or mold toxicity: If nuts are consumed in poor condition or in excessive quantities.
Therefore, if you have any special health conditions or are taking ongoing medication, it is advisable to consult a healthcare professional first.
