Brazil nuts are considered healthy and are often part of nut mixes such as trail mix. But there is always uncertainty, because Brazil nuts are radioactive.

Ingredients of the Brazil nut: Healthy and radioactive

Brazil nuts have it all: With a fat content of 60 to 70 percent, they are particularly high in calories. However, because these are mainly monounsaturated and polyunsaturated fatty acids, nuts are actually very healthy in moderation. They also contain the minerals calcium, magnesium and phosphorus and thus promote the growth of bones and muscles. The zinc content of the Brazil nut is also not to be scoffed at.

The Brazil nut is particularly valued because of the high amount of selenium: The nut is the largest natural supplier of the trace element and just one nut covers the daily requirement. Selenium helps to strengthen the immune system and detoxifies the body. Selenium is only found in comparable amounts in fish, meat and eggs. In addition, the Brazil nut contains a lot of vegetable protein. It is therefore particularly suitable for a vegetarian and vegan diet.

Brazil nuts are naturally radioactive. Their radium content is 1000 times higher than that of other foods. Nevertheless, it is harmless if you only eat Brazil nuts every now and then.

Brazil nuts: Toxic or not?

Despite its many healthy ingredients, the Brazil nut also has a reputation for being harmful to health. Elevated levels of the mold toxin aflatoxin, which can be carcinogenic even in small amounts, have been found in Brazil nuts from Brazil. As a result, restrictions on the import of Brazil nuts were imposed by the EU. Because many countries of origin cannot meet the high requirements contained therein, the trade in Brazil nuts has declined sharply.

Aflatoxins are found in many dry products, such as grains, legumes, nuts and tea leaves, and can form quickly if stored incorrectly. They are also heat-resistant, so they can withstand cooking and baking processes. It is best to keep peeled Brazil nuts cool and dry and consume them quickly. If they have a musty, rancid taste, stop eating them. You can store unpeeled Brazil nuts for about two to three months.

The Brazil nuts that are available from us in Germany are carefully checked. In a recent report by the Federal Office for Consumer Protection, low aflatoxin levels were found almost exclusively in Brazil nuts – the green light for Brazil nuts.

Brazil nuts: Healthy, but not sustainable

All Brazil nuts available from us are imported from the tropical regions of South America or the Ivory Coast, so they have long transport routes behind them. This is problematic because a lot of environmentally harmful CO2 is emitted with the import.

Brazil nut trees are not cultivated, so the nuts are collected from wild trees. There are no monocultures with the use of pesticides, but collecting the nuts prevents the tree from spreading naturally – and that in the already endangered rainforest. When shopping, you shouldn’t always just grab Brazil nuts, but also try out local nut varieties?
