14 Ways How Onions Add Punch To Your Food And Health.
The onion, known scientifically as Allium cepa, derives its name from the Latin word unio, which means “single,” or “one”—reflecting of the onion plant producing a single bulb, unlike its cousin, the garlic, that produces many small bulbs. The name also describes the onion bulb when cut down the middle; it is a union (also from unio) of many separate, concentrically arranged layers.
Varieties of Onion:
Onions come in a variety of shapes, sizes, colors, and tastes but can be categorized into generally two types of large, globe-shaped onions, classified as spring/summer or storage onions. In addition to these large onions, there are also smaller varieties such as the green onion, or scallion, and the pearl onion.
- White onion: medium to large in shape, with a white papery skin and evenly white flesh. They have a strong flavour and are good for stuffing or baking; only use raw in salads if you want an assertive onion flavour.
- Yellow/Brown onion: a good all-purpose onion, with a light golden skin and yellow flesh.
- Spanish onion: has a similarly coloured skin to a yellow/brown onion, but is usually bigger, as well as sweeter and milder – good for omelettes, salsas and stir-fries.
- Red onion: varies in size, but has a distinctive red/purple skin, and the edge of each of its white rings is tinged with red. The flavour is mild and quite sweet. Good for salads, marinades, salsas and roasts.
Onions are a major source of polyphenols in general, and also of flavonoids (a very important subdivision of polyphenols). In general, red onions are higher in total flavonoids than white onions, with yellow onions falling somewhere in between.
Why Onions Make your Eyes Water:
When chopped, onions produce a volatile, sulphur-rich oil that makes eyes water. Many ways to prevent this have been tried- freezing the onion; wearing goggles or holding your breath – but they are rarely completely effective. The best way is to not cut through the root of the onion, as this is where most of the oil resides.
History of Onions:
Onions are native to Asia and the Middle East and have been cultivated for over five thousand years. Onions were highly regarded by the Egyptians as currency and also placed in tombs of kings. Onions were an indispensable vegetable in the cuisines of many European countries during the Middle Ages. It was Christopher Columbus who brought onions to the West Indies; their cultivation spread from there throughout the Western Hemisphere.
14 HEALTH SECRETS OF ONION TO CRY FOR:

- Cardio Care: Vitamin B3, a potent antioxidant flavonoid – quercitin, and organosulfur compounds in onions, significantly help to correct thrombosis, thin the blood, retard blood clotting, increase HDL (good cholesterol) levels while decreasing the bad cholesterol (LDL), prevents atherosclerosis, the hardening and thickening of the arteries due to plaque, and prevent heart attacks.
- Improves Immunity: Along with flavonoids, onions have some superior micro minerals, such as selenium and fluorine that have antibiotic and antioxidant properties to boost immunity. The pungency of onions increases blood circulation, causes sweating, and wards off infections from colds and flu.
