Onion
A truly nutritious ingredient
It is one of the few ingredients that are actually consumed on all continents, from east to west and from north to south. From a botanical point of view, it is a bulb with a two-year life cycle. It is very versatile but prefers soils rich in water. The plant is able to resist the cold, although it does not tolerate temperature variations. Whether used as a condiment or as a main ingredient, onion always provides a certain amount of nourishment.
It contains a lot of fibre; therefore, it is able to support digestive processes, normalising the intestinal flora. It is rich in mineral salts such as sulphur, iron, potassium, magnesium, fluorine, calcium, and manganese. Onion also contains some antioxidants, such as flavonoids (which, among other things, have a diuretic action) and glucoquinin, which has an anti-diabetic function.
The most common types of onions
There are many types of onions, each of which is distinguished by colour, size, shape, and flavour. Here are some of the most popular varieties in Italy:
- Tropean red. It is the queen of onions, the one richest in antioxidants. It is characterised by an aromatic flavour tending towards sweetness, to the point of being consumed raw.
- It is a large variety, very tender, and has a tasty but not very intense flavour. It is used in pastries rather than baked in the oven.
- White onions from Barletta. It can be eaten raw or, more accurately, dipped in oil due to its extremely mild flavour.
- Golden Parm. It is one of the most consumed onions ever; it has a pungent flavour and is usually used for sautéing.
- It is a typically Umbrian variety. Externally, it resembles the Tropean Red; however, it is mainly used in the preparation of soups, given its delicate flavour.
- Ramata of Milan. It is characterised by an intense and medium-pungent flavour. It’s mostly used to make the traditional fried onion rings.
- Roscoff Rose. This is a very unique variety belonging to the Allium Cepa family. It is not so famous in Italy, and it is quite expensive. It is a traditional product from the Brittany town of Roscoff, which is situated on Finistère’s northern shore.
- Living Water. It is a very sweet product and has a peculiarly flattened shape. The living water onion is very rich in flavonoids, which are powerful antioxidants that fight the harmful actions of free radicals.
- Castrofilippo Paglina. It is a sweet variety with notable dimensions ranging from 500 g to over 2 kg, with rounded or heart-shaped bulbs of a brownish-white colour.

Who shouldn’t eat onions? Here are the contraindications
Onion is quite digestible but still requires the help of the digestive system, especially if there are some pathologies or conditions capable of weakening the digestive system. The reference is to those suffering from stomach acidity, gastritis, ulcers, and irritable bowel syndrome.
It is rumoured that onions can only be digested when cooked. They contain digestive enzymes, which could undergo a degradation process if cooked.
