Some of the healthiest parts of vegetables and fruits get thrown away, such as the onion skin, melon rind and orange peel.

The skin is not edible, but its benefits can be extracted by adding them in soups and stews, and removing them at the end.
The next time you are preparing a soup, add a whole onion or two, along with the scales into the pot. This way you will extract quercetin and other beneficial compounds that are included in onions. Also, you can keep the onion scales in a paper bag. In a cut-off leg of a pantyhose or a thin sock put a handful of onion skins and tie it up loosely. When the soup is cooked, throw away the skins.
