leeks health benefitsLeeks (Allium porrum) are a vegetable that belongs to the same botanical family as chives, garlic, onions, scallions and shallots, in the genus Allium. However, unlike its fellow members, leeks do not form bulbs. The edible part of the leek plant is the white onion base and light green stalk (or stem), while the dark green leaf sheaths are usually discarded.

Leeks are believed to be originated in the Mediterranean and Middle East. They have been grown and used for cooking for more than 3,000 years in Asia and Europe regions.

Just like onions, leeks can be served either cooked or raw, but make sure to just use the whitest part of the plant. Leeks have a mild onion-like flavor that works well in soups and a variety of other dishes. Apart from that, Leeks also have several health benefits that are similar to those of garlic and onion.

Leeks are available all year long, and peak in the fall and winter. When buying leeks, look for those with fresh, bright green leaves, and avoid any with blemishes, wilting or yellowing leaves. Choose smaller leeks as they tend to be more tender.
