Onions are a very good source of vitamin C, B6, biotin, chromium, calcium and dietary fibre. In addition, they contain good amounts of folic acid and vitamin B1 and K.
A 100 gram serving provides 44 calories, mostly as complex carbohydrate, with 1.4 grams of fibre.
Like garlic, onions also have the enzyme alliinase, which is released when an onion is cut or crushed and it causes your eyes to water.
They also contain flavonoids, which are pigments that give vegetables their colour. These compounds act as antioxidants, have a direct antitumor effect and have immune-enhancing properties.
Onions contain a large amount of sulfur and are especially good for the liver. As a sulfur food, they mix best with proteins, as they stimulate the action of the amino acids to the brain and nervous system.
The onion is the richest dietary source of quercitin, a potent antioxidant flavonoid (also in shallots, yellow and red onions only but not in white onions), which is found on and near the skin and is particularly linked to the health benefits of onions.
Quercitin has been shown to thin the blood, lower cholesterol, raise good-type HDL cholesterol, ward off blood clots, fight asthma, chronic bronchitis, hay fever, diabetes, atherosclerosis and infections and is specifically linked to inhibiting human stomach cancer.
It's also an anti-inflammatory, antibiotic, antiviral, thought to have diverse anti-cancer powers. Quercitin is also a sedative. So far, there is no better food source of quercitin than onion skins.
