Description

Onions are known to be rich in biotin. Most of the
flavonoids which are known as anti-oxidants are
concentrated more in the outer layers, so when you peel
off the layers, you should remove as little as possible.
Onions, like garlic, are also rich in sulphur compounds.
Onions are known to contain manganese, copper, Vitamin
B6, Vitamin C and dietary fibers along with phosphorus,
folate and copper.
