ONIONS AND THEIR PROPERTIES

The onion is the bulb of a plant belonging to the Liliaceae family and is characterised by large and cylindrical leaves.
Depending on the amount of sun it receives, the taste of the onion will be strong and sharp or mild. The sweetest onions come from the sunniest climates. By contrast, those grown in climates with little sun are the sharpest.

The bulb does not have a high calorific content, providing some 20 calories per 100 grams to the diet. Onions contain vitamin A, niacin (nicotinic acid) and vitamin B2.

ORIGIN AND PROPERTIES: The primary origin of the onion is in Central Asia. A secondary centre is the Mediterranean as it is one of the oldest vegetables used for consumption. The first references date back to 3,200 BCE as they were cultivated by the Egyptians, Greeks and Romans. During the Middle Ages, cultivation was developed in Mediterranean countries where large bulb varieties were selected that gave rise to modern varieties.

The onion is a very important food because of its contribution to a healthy and balanced diet. The high concentration of vitamins, mineral salts and energetic properties in the Spanish onion are mainly due to two factors: the MEDITERRANEAN CLIMATE and the SOIL QUALITY in Spain

The onion is scientifically recognised to be beneficial against many diseases such as: diabetes, sciatica, rheumatism, bronchitis, colds, etc.. It also has anti-anaemia properties and because of its iron, phosphorous and mineral content helps to restore blood loss and red blood cells, protecting against infections and regulating the digestive system. It is an essential component in a healthy diet.

Diuretic: Encourages the elimination of body liquids, very effective in cases of rheumatism, gout, dropsy, oedema, and blisters.

Bactericide: Owing to its content of sulphur-rich compounds, together with garlic it is one of the best natural remedies against infectious processes of the respiratory tract (influenza, bronchitis, pharyngitis, etc.) and digestive intestinal putrefaction, diarrhoea, etc.. Onion mixed with honey in equal parts clears the voice and resolves the problem of snoring.

Digestive: Encourages digestion by stimulating the liver, gallbladder and pancreas, although it should be avoided in cases of hyperchlorhydria (heartburn) as well as sensitive stomachs.

Allergies: Its flavonoid content is very useful for reducing allergic reactions to pollen.
