What it is

Leeks are a member of the allium (onion) family, related to onions and garlic. They have a mild, onion-like flavor and a long, white stalk with green leaves. Leeks are grown in soil and harvested for their edible stalk and leaves.

Why it's used

International bodies like JECFA have evaluated leeks, but no specific health concerns are associated with their typical consumption in food. Evidence does not suggest significant health risks from leeks when consumed as part of a balanced diet.
