Wheatgrass is rich in magnesium since this is the core mineral found in every chlorophyll molecule. Magnesium has a relaxing and dilating effect on the blood vessels. It can relax constricted blood vessels and make them larger so that blood can flow freely and pressure on the walls of the blood vessels will be lessened.
The antioxidants in wheatgrass prevent oxidation of cholesterol in the blood, or when the cholesterol sticks to the walls of the blood vessels. Antioxidants prevent cholesterol plaque formation or atherosclerosis.
The fiber in wheatgrass also prevents absorption of cholesterol from the food, thus regulating cholesterol level in the blood.
