Brazil nut- This is a delicious delicacy. During the research, it turned out that the product is incredibly useful. So, how does a Brazil nut grow, and what useful qualities has?

What is this exotic product? Of course, this is a nut that grows in distant Brazil. Thanks to trade relations, the product appeared in Russia, but relatively recently. Few people know, but these nuts are very healthy and nutritious.

ABOUT beneficial properties ah, contraindications and how much of the product should be consumed per day, we will find out below in the article.

How does the exotic Brazil nut grow?

Tree on which Brazil nut grows

This product grows on the Bertoletia tree. It was named after the great French chemist Claude Louis Berthollet. The tree grows in the Amazon rainforest. This is quite an impressive plant, reaching a height of about 50 meters, with a trunk diameter of 2 meters. The tree has smooth bark and large leaves that are collected in clusters.

Interesting fact: the leaves, together with the fruits, are located almost at the very top of the plant.

The tree grows for about 500 years, but begins to bear fruit at the age of 12. Sometimes there are specimens that live up to 1000 years. It is not easy to collect fruits from such a height, but this is not necessary, because they themselves fall to the ground.

The shell of the product is thin, but extremely durable. If it doesn’t break during the fall, you will have to try hard to get the most delicious thing. The inhabitants of these places, namely capuchin monkeys, have greatly succeeded in this matter. Animals split fruits on stones.

Interesting fact: the rich wildlife of these places contributes to the natural spread of the plant. For example, relatives of guinea pigs are agoutis. They, like capuchin monkeys, are capable of splitting this fruit with their sharp teeth. These animals store a huge amount of nuts from this plant “for a rainy day” and bury them in the ground, and then forget this place. Over time, a new tree grows in place of the buried Brazil nuts.

By the way, nuts themselves do not grow on a tree, they are collected in a so-called cauldron, which is called a fruit. Its size is equal to the size of a coconut. It is inside such a “cauldron” that the nuts grow, which are nicknamed in Brazil as chestnuts-from-the-Pair.

In winter, all the leaves fall from the tree, and in spring, flowering occurs all at once in one day. After which the fruits begin to ripen. Their maturation lasts about a year. Such a long period is associated with a dense shell. Towards the end of winter, the “kettles” begin to fall to the ground.

This fruit with nuts inside weighs about 2 kilograms. The shell is similar in composition to wood. Its thickness is 1 cm. Inside each “pot” there can be from 8-24 nuts. The size of the nut can be compared to an orange slice, i.e. relatively small.

An interesting fact: such trees cannot be found in every tropical forest, but they grow only in forests untouched by man, where they feel free and at ease. Bertoletia does not grow in swampy areas, only on solid soil. Sometimes trees populate a certain area too densely, and often there can be one tree per several hectares.

In order to get tasty treat, you first need to cut off the top of the “kettle”. After which, they begin to peel the nuts themselves, and their shells are similar in hardness to. So, this process generally takes quite a lot of time.

In addition, this plant does not grow throughout Brazil, but only in a few states. And in order for nuts to be available in all stores in Brazil, they also need to be diluted. This accounts for its high cost, and this is only in this country, let alone Russia.

It began to appear in our country recently, but is still inferior in popularity to walnuts and hazelnuts, due to the high markup. On average, the price per kilogram of this delicacy in different regions varies from 1,750 to 2,500 rubles.

In addition to this state, nuts grow in Rondonia, Amapá, Maranhão, etc.
Today, these trees are listed in the Red Book, because every year there are fewer and fewer of them due to deforestation.

It is long-lived (500 years or more) and reaches a height of 30-45 m. The trunk with a diameter of up to 1-2 m, is even and straight, branches at approximately ¾ of the height and forms an even spherical crown.

Pollination and fruiting

Abundant fruiting is possible only in the untouched virgin forests of the Amazon, where bumblebees and large bees of certain genera - pollinators - live in sufficient numbers. This is due to the structure of the plant’s flower and the characteristics of the nectar. Only large insects with long proboscis can reach it. Moreover, Bertoletia’s eternal companions are orchids, attracting bees and bumblebees with their aroma.

What is it?

Brazil nut, or Bertoletia talla ( Bertholletia excelsa) is one of the largest trees in the Amazon rainforest. You can see what it looks like and how it grows in the photo.

The trunk of such a giant can reach 45 meters in height and up to 2 meters in diameter.

Bertholetia fruits are not nuts, from a botanical point of view, but huge boxes containing grains inside, which we call nuts.


Compound

100 grams contain:

  • 647 kcal;
  • 15 g protein;
  • 65.8 g of fat (most of all monounsaturated fatty acids palmitoleic and oleic);
  • 7.35 g vegetable fiber;
  • 2709% of the daily dose of selenium;
  • 94.5% magnesium;
  • 87.5% copper;
  • 70% phosphorus;
  • 59.5% manganese;
  • 42% thiamine (vitamin B1);
  • 28% vitamin E and zinc each;
  • 17.5% calcium and potassium each;
  • 14% iron.

The most important component in the composition of Bertoletia is selenium. This is what determines the benefits of Brazil nuts.

We talk a lot about how important it is to get antioxidants from food. But in fact, one of the strongest antioxidants is synthesized in the body. This is glutathione. The antioxidant activity of glutathione is so high that it is even called the “mother of all antioxidants.”

But with a lack of selenium, the synthesis of this compound is suspended.

That is why products containing this microelement, and above all, Brazil nuts, significantly increase overall resistance to the negative effects of free radicals. They saturate the body with selenium. And this makes it possible to enhance the biosynthesis of glutathione.

Useful properties

Anti-inflammatory and antioxidant activity

The most striking beneficial property of Brazil nuts is its ability to fight inflammatory reactions. Bertoletia contains ellagic acid, which has strong anti-inflammatory properties, including the ability to suppress inflammation in the central nervous system.

Selenium is even more important, as it ensures the synthesis of glutathione, which regulates the functioning of T cells. immune system and the production of leukotrienes, as well as having antioxidant properties.

The next component of the nut that is responsible for reducing the level of chronic inflammation is oleic acid. The same fat that predominates in olive oil and the abundance of diet which is largely explained.

Due to its high anti-inflammatory and antioxidant activity, Brazil nuts are useful for:

  • prevention of cardiovascular diseases;
  • protection against cancer;
  • improvements appearance skin (treating pimples and acne), prolonging the youth of the skin;
  • strengthening immunity.

Maintaining Thyroid Health

Most people know that iodine is necessary to maintain normal functioning of the thyroid gland. This is why consumption plays such a prominent role in the body's hormonal health.

But not everyone knows that selenium is no less important for the thyroid gland than iodine. Meanwhile, without this microelement, the production of active thyroid hormones is impossible. Selenium deficiency is one of the causes of hypothyroidism.

The use of Bertoletia reliably protects against a deficiency of this substance. And that's the point special benefit Brazil nuts for women, since thyroid diseases affect the fair half of humanity more often than men.

Other healing properties
