Leeks are full of compounds known as allyl sulfides, which have been proven to modify specific pathways that are associated with tumor development. By eating more leeks, you'll be able to reduce the likelihood of a tumor developing.
2. They protect against heart disease
Research has shown that leeks are able to slightly lower your blood pressure, which can help stop platelets in your blood from clotting, thereby reducing your chances of having a heart attack. Leeks are also able to flush out homocysteine from your body, which is a chemical that can damage your cardiovascular health.
Leeks are a good source of the flavonoid kaempferol, which is used by your body to protect the linings of blood vessels, especially against reactive oxygen species and free radicals. It can also increase nitric oxide production, which is a chemical that relaxes your blood vessels and decreases your risk of experiencing hypertension.
4. They lower the risk of chronic inflammatory diseases
Leeks are able to combat low-level inflammatory states like obesity, rheumatoid arthritis, and even diabetes, thanks to the large amounts of kaempferol and polyphenol they contain.
If you're trying to shed some pounds, then you'd better start reaching for the leeks. This is because, in addition to their low calorific value, they also contain a considerable amount of fiber, which will help to boost your metabolism and keep you feeling full for longer.
6. They contain plenty of antioxidants
Leeks contain powerful antioxidants known as polyphenols. These will help your body to fight against free radicals, thereby slowing down aging and reducing your chances of contracting a chronic illness.
Leeks should be on every pregnant woman's shopping list since they contain a bioactive form of folate that's known as 5-methyltetrahydrofolate. It is highly important for pregnant women to consume folate since it is key to preventing birth defects.
8. They are packed with minerals and vitamins
Leeks are an incredible source of many potent vitamins and minerals, including magnesium, manganese, iron, vitamin C, K, A, and B-6.
