Coconuts can be dangerous, especially when falling from a palm and striking you on the head. But it has to be considered an urban legend, that a considerable number of people per year die because of this fruit. In Vila do Abraão on Ilha Grande they can say: You have been warned.
The typical German doesn’t have too much contact with coconuts. One or two times in a lifetime we get a ripe coconut and use a drilling machine to get to its content. Or maybe when we are are into cooking Asian meals, we might get a can of coconut milk from the supermarket. But that’s all nothing against a green coconut.
In Brazil you can get coco verde at many different places, typically stored in ice water to keep the nut and the coconut water chilled. Afterwards the well-trained coconut salesman prepares the coco verde with his blade and five to six strikes. There is nothing as refreshing as drinking cool coconut water with a straw directly from the coconut.
And it is even healthy: Coconut water contains lots of magnesium and is therefore a really good prevention for cramps. While travelling Brazil I got that much addicted to coconut water, that I had to order some of it over the Internet afterwards. But it is not as good as drunken directly from this dangerous fruit.
