4Walnut
Walnut is beyond a snack, really. It is a robust combination of numerous healthy elements. Its l-arginine content is necessary for the production of nitric oxide in the endothelium of blood vessels. Now, nitric oxide is a potent vasodilator, and plays a vital role in increasing blood flow in cases of constriction or lack of nutrients in tissues. Walnut is rich in alpha- linolenic acid, an essential fatty acid which maintains the elasticity of blood vessels. A study revealed that people who consume walnut on a regular basis for up to 8 weeks would have reduced blood pressure and improved blood flow. [4]
