This method of protecting blood vessels also produces a naturally occurring gas called nitric oxide or NO. Nitric oxide helps dilate and relax blood vessels.

Another advantage of the leek is its concentration of folate, which is in its bioactive form and is in fact present in all parts of the plant.

Folate promotes heart health and ensures homocysteine levels are in proper balance. Even moderate amounts of homocysteine can bring harm to the cardiovascular system.

Folate breaks down homocysteine into beneficial amino acids.

Leeks also contain high amounts of polyphenols.

Polyphenols are antioxidants that play a crucial part in protecting both blood vessels and blood cells from oxidative damage.

Lastly, it contains a substantial amount of dietary fiber

Dietary fibre is important in improving cardiovascular health and prevents heart attacks, strokes, and other cardiovascular disorders.

Fibre helps in the elimination bad cholesterol and prevents plaque formation within the arteries.

Leeks can also assist in lowering Blood Pressure

Potassium serves as a vasodilator which minimises the tension from the blood vessels to provide smooth flow of blood through the arteries.

Leeks are abundant in this nutrient. Potassium also helps maintain homeostatic balance between sodium and plays an important role in overall heart muscle contractility.
