Nutritional Properties of Leeks

Leeks are a member of the onion family, and have been cultivated since the time of the Ancient Egyptians. Asian and European cultures have been growing and cooking leeks for more than 3,000 years. Leeks have a sweet flavor, and can be eaten raw or cooked.

A cup of leeks is low in sodium and has almost no saturated fat or cholesterol. Leeks are a good source of dietary fiber, vitamin B6, iron and magnesium, and a very good source of folate as well as vitamins A, C, and K.

Health Benefits of Leeks

  • Contain many flavonoid antioxidants (including diallyl disulfide, diallyl trisulfide, allyl propyl disulfide).
  • Have antioxidants, antimicrobial properties, and liver-protecting properties.
  • Reduce level of liver enzymes.
  • Reduce fatty liver (liver triglyceride accumulation) caused by high-fat diets.
  • Improve lipid profile by decreasing total cholesterol and triglyceride levels while raising good cholesterol levels.
  • Improve high blood pressure by increasing production of nitric oxide, a naturally occurring gas that helps dilate and relax blood vessels.
  • Decrease production of asymmetric dimenthylarginine (a substance that blocks production of nitric oxide).

Tips for Using and Storing Leeks

  • Leeks are a great addition to many dishes including soups, salads and casseroles.
  • To wash leeks, cut them in half lengthwise, keeping the root intact. Run water over the whole leek, rifling through the layers to give them a good rinse. If needed, do this a few times to make sure all of the fine sand is removed.
  • Store fresh leeks unwashed and untrimmed in the refrigerator, where they will keep fresh for 1 to 2 weeks. Wrapping them loosely in a plastic bag will help retain moisture.
  • Leeks should have firm, crisp stalks with as much white and light green regions as possible. Do not eat leeks with yellow or withered tops.
  • Cooked leeks are highly perishable, and even when kept in the refrigerator will only stay fresh for about 2 days. 
  • Leeks can be frozen, pickled, canned or dehydrated. To freeze leeks, trim and then blanch them for 2 to 3 minutes in boiling water. Cool rapidly, towel dry, and place in freezer bags.
