CAVOLETTI DI BRUXELLES
Inizio subito dicendo che non mi piacciono i cavoletti o cavolini di Bruxelles comperati al supermercato, ma quelli coltivati nel mio orto sono tutta un'altra cosa: davvero buoni. Insieme a spinaci, pomodori e zucchine è l'ortaggio che vale la pena avere nel proprio orto.
I cavolini sono varietà coltivate nei paesi del nord Europa, in Belgio appunto. Prediligono perciò estati non molto calde ma inverni poco rigidi. In Italia vengono bene nelle regioni settentrionali. La zona di più larga coltivazione è l'Inghilterra.
I cavolini sono grumoli ascellari sferici, che crescono sul fusto, alla base delle foglie. Ogni pianta produce 30/40 cavolini, che maturano quasi contemporaneamente. I cavolini si raccolgono quando hanno un diametro di circa 3 cm.
Coltivazione
Il ciclo di produzione dei cavolini di Bruxelles è di circa 4 mesi. Si raccolgono a partire da settembre e a seconda delle specie si può arrivare a raccogliere cavoletti fino a primavera.
In pianura padana: se trapiantate le piantine questa operazione deve essere fatta tra luglio e al massimo i primi di agosto. Si raccolgono da agosto a dicembre.
Se invece volete partire dai semi, bisogna iniziare un po' prima di maggio perché le piantine germogliano quando la temperatura è intorno ai 20°.
È possibile anche coltivarli in vaso, scegliendo varietà nane, che arrivano ad altezze massime di 60/70 cm. In questo caso, è necessario procurarsi vasi profondi almeno 40 cm.
Hanno bisogno di azoto e potassio nel terreno, che si può facilmente fornire con stallatico o concimi appositi.
Bisogna prestare attenzione ai ristagni d'acqua per non fare marcire le radici: bisogna annaffiare tutti i giorni appena trapiantate le piantine e diradare poi quando si sono ben radicate.
Per farli crescere meglio, si possono cimare le piante. La cima della pianta si può mangiare come fosse un cavolo.
Proprietà nutrizionali
I cavolini sono indicati contro le anemie, avendo buone quantità di ferro (se volete informazione su come assumere correttamente ferro dagli alimenti guardate qui un articolo con la consulenza del professor Giorgio Lambertenghi Delilieris, già direttore del Dipartimento di Ematologia della Fondazione IRCCS Ospedale Maggiore di Milano).
Hanno proprietà disintossicanti.
Stimolano la concentrazione e l'attività cerebrali grazie alla presenza di tiamina e acido folico.
Sono utili alla protezione delle ossa grazie alla vitamina K.
Sono ricchi di antiossidanti, prevengono cioè l'ossidazione cellulare, in particolare del DNA, causata dai radicali liberi che si formano in processi indispensabili per il nostro organismo, come la trasformazione degli zuccheri ( approfondimento qui).
Sono tra i cibi più ricchi di fibre e quindi sono molto utili per l'intestino.
Contengono anche carboidrati, zuccheri, sodio e proteine ma non contengono colesterolo.

I'll start right away by saying that I don't like sprouts or Brussels sprouts bought at the supermarket, but those grown in my garden are quite different: they are really good. Along with spinach, tomatoes and zucchini Brussels are worth being grown in your home garden.
Sprouts are varieties grown in the countries of northern Europe, in Belgium more precisely. So they don't like hot summers and they prefer mild winters. In Italy they are grown in the northern regions. The area of greatest cultivation is England however.

Sprouts are spherical axillary granules, which grow on the stem, at the base of the leaves. Each plant produces 30/40 sprouts, which ripen almost simultaneously. The sprouts are collected when they have a diameter of about 3 cm.
Cultivation
The production cycle of Brussels sprouts is about 4 months. They are harvested from September and depending on the species you can get to pick up sprouts until spring.
In the Po Valley the transplantinf of the seedlings must be done between July and August. They are collected from August to December.
If you want to start from the seeds, you have to start a little before May because the seedlings sprout when the temperature is around 20 °.
It is also possible to grow them in pots, but in this case you have to choose dwarf varieties, which reach a maximum height of 60/70 cm. In this case, it is necessary to obtain deep vessels at least 40 cm.
They need nitrogen and potassium in the soil, which can be easily supplied with manure or special fertilizers.
We must pay attention to the stagnation of water so as the roots don't get rotten: we must water the plants every day as soon as we transplant the seedlings and then thin out when they are firmly rooted.
To make them grow better, plants can be clipped. The top of the plant can be eaten as if it were a cabbage.
Nutritional properties
The sprouts are indicated against anemia, having good amounts of iron (if you want more information on how to properly take iron from foods look here an article with the advice of Professor Giorgio Lambertenghi Delilieris, former director of the Department of Hematology of the IRCCS Ospedale Maggiore Foundation in Milan ).
They have detoxifying properties.
They stimulate the concentration and activity of the brain thanks to the presence of thiamine and folic acid.
They are useful for bone protection thanks to vitamin K.
They are rich in antioxidants, that is, they prevent cellular oxidation, in particular of DNA, caused by free radicals that are formed in processes essential for our body, such as the transformation of sugars (study here).
They are among the foods rich in fiber and therefore are very useful for the intestine.
They also contain carbohydrates, sugars, sodium and proteins but do not contain cholesterol.
