Leeks are a typical winter vegetable that have a light green color and are a milder and sweeter version of an onion. They contain vitamins B1 and C, and are abundant in iron, magnesium, calcium and phosphorus. Leeks are good for digestion, help stimulate the liver and gall bladder, and have been shown to lower blood sugar. Along with being very healthy, leeks are also an extremely versatile ingredient that can be used in many different dishes.
