A close relative of onions and garlic, leeks have a mild onion-like flavor that works well in soups and a variety of other dishes. Leeks have been documented in ancient Egypt and Mesopotamia. They are also a very hardy plant and easy to cultivate.
Leeks Are Good for Your Eyes
Leeks contain a considerable amount of vitamin A. A serving of leeks contains roughly 65% for women and 50% for men of the daily recommended allowance of vitamin A. Vitamin A is necessary for healthy blood cell development. Vitamin A also aids in the growth of new red blood cells and white blood cells and is known to help your retinas function under low light conditions.
Leeks Are Good for Your Bones
If you want to keep your bones healthy, add leeks to your diet. Leeks contain a high amount of vitamin K, which is known to help in regulating blood flow. Low levels of vitamin K are associated with poor circulation. Vitamin K in leeks helps activate the protein osteocalcin, essential for bone health. One serving of leeks contains nearly 50% for women and almost 40% for men of the daily recommended allowance of vitamin K.
Leeks Are Good for Your Heart
Leeks belong to the allium family, and recent studies have shown that this family has a blood pressure-lowering effect. Studies are currently being done on leeks, and promising results have found that leeks can help prevent platelets from clotting, which could help protect you against a heart attack. Leeks can help rid your body of homocysteine, a molecule that can be detrimental to cardiovascular health. Plus, leeks have been found to help lower the bad cholesterol (LDL) while raising the good cholesterol (HDL).
Leeks Help to Protect the Lining of Blood Vessels
Research has found that leeks contain substantial levels of flavonoid kaempferol. Kaempferol helps protect blood vessels’ lining, especially against free radicals or reactive oxygen species. The flavonoid may also increase nitric oxide production, a substance that acts as a natural dilator and relaxant of blood vessels in the body. This action allows blood vessels to rest and begin to lower the risk of hypertension.
Leeks May Help to Prevent Some Cancers
As mentioned earlier, leeks belong to the allium family and are known to contain compounds that have been known to fight stomach and colorectal cancer. Researchers have found that allyl factors which are in leeks can inhibit these cancers. Studies are currently being done, and promising results have shown that allyl factors may help to prevent breast, colon, lung, and esophageal cancer.
