Leeks
Leeks have all of the healthy properties of the Allium family as described above. However leeks also contain these nutrients:

• Vitamin B6
• Vitamin C
• Folate
• Manganese
• Iron
• Fiber

This particular combination of nutrients makes leeks particularly helpful in stabilizing blood sugar, since they not only slow the absorption of sugars from the intestinal tract, but help ensure that they are properly metabolized in the body. Remember, the stabilization of blood sugar is one of the most important goals of the Perricone Promise. Spikes in blood sugar accelerate aging, wrinkles and a host of degenerative diseases.

We all know that onions and garlic are important for imparting delicious flavor to a meal. However, when we include leeks, we raise the flavor of the meal from delicious to "sublime." They are particularly delicious with fish such as halibut, chicken and fish and chicken soups.
