What are the benefits of Leek?

Leeks are a member of the Alliaceae family and are scientifically known as Allium porrum. The main edible portion of the vegetable is the stem or the stalk which is nothing but a bundle of leaf sheaths and also the white onion base. They have a mild onion like taste and are quite crunchy and firm in their raw forms. Different varieties of the vegetable are available and are broadly categorized as the summer varieties and the overwintering leeks. Two of the most popular and commonly cultivated varieties are the Tadorna Blue and King Richard. Physically, they resemble scallions but are much bigger and are usually around 12 inches in length and around 2 inches in diameter. They have a small bulb like structure and a cylindrical stalk of superimposed leaves. Being a high source of vitamins and minerals, the vegetable plays an important role in providing defense against a number of ailments and diseases. It also helps to promote optimal health and strengthens the immune system of the body. Some of the major health benefits of consuming leeks are given below.

A flavonoid called kaempferol is present in significant amounts in leeks. Kaempferol provides protection to the linings of the blood vessels, particularly against free radicals or reactive oxygen species. Kaempferol could also induce the increased production of nitric oxide, a substance that acts as a natural dilator and relaxant of the blood vessels. Therefore, it allows your blood vessels to rest and decreases your risk for hypertension.
