Leeks are in the same family (Allium) as onions and garlic. They contain many of the same beneficial phytonutrients as other members of this family, although there have not been many studies of the health benefits of leeks in particular. We don't eat the tough dark green leaves - just the white and lighter-green parts.

Health Benefits of Leeks

Leeks are a very good source of vitamin K (the more of the green part eaten, the more the vitamin K), vitamin A, and manganese, and a good sources of vitamin C and folate. They are also good sources of phytonutrients such as flavonoids and polyphenols, which can protect cells from damage, lower risk of cardiovascular disease, and provide other health benefits.

  Leeks are especially high in a phytochemical called kaempferol, which has been shown to be protective of the linings of our blood vessels.

How to Cook with Leeks

Leeks are used a lot in Europe, but people in North America are less familiar with them.  They have a flavor similar to onions, but somewhat milder.

  They can be used in most recipes where onions would be used, and are wonderful in soups and stews. 

To prepare leeks, cut off the toughest green parts, and then slice them lengthwise to clean, as sand is often caught between the layers down near the bulb.  Then slice and cook as you would an onion.
